Description

Automatic valve position measuring apparatus for each room heating system

The present invention relates to a method for automatically controlling the valve opening amount in each room heating system. More particularly, the heating imbalance problem caused by the pipe length or the external environment in each room heating system is supplied to each room after measuring the return temperature of each room. By controlling the amount of heat to be proportionately controlled, and distributing and supplying the required amount of heat in the heating pipes of different rooms with different heating areas, the heating temperature of each room can reach the equilibrium state. By inventing it, the efficiency and energy of heating can be greatly reduced.

Generally, a boiler is used to heat water by using combustion heat and heat generated by burning it using fuel, coal or gas as fuel, or supplying electricity to a heater, and supplying hot water to various heating facilities In the case of a domestic boiler, hot water is supplied to the piping installed on the floor of the room or the like, and is used for supplying hot water through a water pipe or the like.

On the other hand, in buildings with several rooms, such as inns, test houses, and studios, each room is equipped with a separate room temperature controller, an energy-saving automatic heating system that separately controls the room temperature. Each room is equipped with a heating system.

Looking at the configuration of each room heating system, such as a heating source or individual boiler, each room controller and several room cones installed in each room, the living room installed in each room to monitor the status of hot water use, including the heating conditions of each room A central room cone for heating control of a room (for example, a living room) in which the room cone is installed, a valve for controlling the number of heating in each room (ie, a heating water supply control valve) and a valve driver for controlling opening and closing of the valve Doing.

By the way, when the conventional valve heating system adopts a simple on / off control method, the floor temperature is different depending on the size (pipe length) of the room to be heated. The method of controlling the flow rate of the pipe by installing the sensor has a lot of problems of durability and reliability of the sensor.

In addition, even in the case of controlling the return temperature of each pipe (room) by measuring the return temperature in each conventional heating system, the user must set the length of the pipe (room) in advance or set a target return temperature for each room. There is a problem that it takes a lot of time to follow the inconvenience, and to proportionally supply the heat amount of each pipe, and to correct the frequent trajectory of the valve driver to reach the equilibrium point where the heat amount required for each pipe is supplied Not only is this being done, there is a disadvantage that the equilibrium temperature may not be reached even if the opening amount of the valve is modified through frequent frequent corrections.

On the other hand, in the heating system control method of Korean Patent Publication No. 10-092417, in the heating system control method for controlling the flow rate of the heating water supplied to each room by adjusting the opening degree of each of the plurality of valves installed on the heating water pipe, the heating The return temperature of the water is measured, and the return temperature information is an arrival time for the return temperature to reach a preset set temperature, and the opening amount ratio of each valve is determined according to the ratio of the arrival time. .

In addition, in each room indoor temperature control device and its control method, which adapt to the heating environment of Korean Patent Publication No. 10-0924466, the indoor set temperature set in the room controller of each room is converted into the required heat amount and collected in the valve controller to obtain the required heat amount. The room controller of each room adopts the method of controlling the valve on / off by judging the change of heating environment by comparing the amount of heat supplied by the boiler from the valve controller with the required amount of heat from each valve. have.

In addition, the valve system and the fine flow control method of the domestic Patent Publication No. 10-0809490 and the fine flow control method thereof is provided with a supply pipe for supplying the heating water and a return pipe for returning the heating water and the boiler for supplying and returning the heating water and And a drive motor unit connected to the boiler and configured to automatically adjust a flow rate of the heating water supplied and returned to each of the rooms to control the distributor and the boiler to distribute the heating water supplied and returned to each of the rooms. It has a form consisting of a central controller to finely control the flow rate of the heating water flowing into a plurality of rooms when hot water heating.

However, in the heating system adopting this method, the return temperature information is set to the time required to reach the set temperature and the opening amount ratio is determined according to the ratio of the arrival time of the set temperature. It does not reach the preset return temperature or takes a long time, and also takes a long time to set or reach the return temperature in advance, it may be difficult to calculate the ratio of each valve, and also the length for the heating pipe If you need to receive information, there is an inconvenience that the installer or the consumer must enter the information manually.

In addition, in the case of a flow regulating distributor which is used separately for the same purpose of such a system, the flow regulating distributor and the boiler are not only interlocked, but also vulnerable to environmental fluidity. When heating the boiler, there is a problem that frequent overheating occurs in the boiler, as well as frequent on / off occurs to give the boiler excessive noise.

In addition, the flow rate setting itself is to be done manually during the initial installation of the boiler, so different heating installations are required depending on site conditions, and there is a limitation in flow control because it is vulnerable to field fluidity such as veranda expansion.

The present invention has been devised to solve such a conventional problem, the heating imbalance problem caused by the length of the piping or the external environment in each room heating system after measuring the return temperature of each room, their average value and tapping temperature correction constant Calculate the tapping temperature by using and then calculate the opening amount of the valves by using them to proportionally control the amount of heat supplied to each room, regardless of the size of each room and other environmental conditions. The heating temperature of each heating "on" room is kept uniform and the heating temperature of each room can be reached quickly by equilibrating and supplying the heat required by each heating pipe. Valve opening in each heating system for significant efficiency and energy savings There is provided a method for controlling the same.

In order to achieve the above object, the present invention provides a heat source or a boiler, such as a district heating system, a room controller, a room temperature sensor, several room cones installed in each room, and several valves for controlling the number of heating in each room. Valve opening amount control in each heating system including a plurality of heating return temperature detection sensors for detecting the heating return temperature passing through each valve and several valve actuators controlling the opening and closing of the valves under the control of the controller A method comprising the steps of: detecting, in the controller, a return temperature of each room in which a valve is open for heating among all rooms where a room cone is installed, and storing them in a predetermined place (A); Then operating a first timer embedded in the controller and continuing the count until a first time defined by the first timer has elapsed; When the first time has elapsed, detecting each return water temperature in a state where the valve is open and storing the water at a predetermined place (B); The difference in the return temperature of each room detected after the first time has elapsed and stored in the designated place (B) is calculated for each room after the first time has elapsed. Determining whether the difference in return temperature of the room is within a predetermined saturation judgment temperature range (± X ° C.); As a result of the above determination, if the return temperature difference of all rooms is within the predetermined saturation judgment temperature range (± X ℃), the return temperature of the room representing the maximum value minus the return temperature of the room representing the minimum value Determining whether the temperature is within the predetermined first target temperature (Y1 ° C.) and returning to the initial stage if the temperature is within the predetermined first target temperature; As a result of the above determination, if the return temperature difference of all the rooms is above the determined saturation judgment temperature range (± X ° C), the heating "off" or the heating "on" at any one of the room cones which were previously in the heating "on" or heating "off" state. Determining whether a signal is input and returning to starting the initial first time count if the change signal of the previous state (that is, the heating “off” or “on” signal) has not been input; do.

In addition, if the value is within the predetermined first target temperature (Y1 ° C) as a result of subtracting the minimum value from the maximum value among the return temperatures of each room stored in the predetermined place (B), is the value within the predetermined second target temperature (Y2 ° C) again? Determining; As a result of the above determination, if the result of subtracting the minimum value from the maximum value among the return temperatures of each room is within the predetermined second target temperature (Y2 ° C), the previous tapping temperature correction constant stored in the controller for outflow of the tapping temperature of the heat source or the boiler (K ) Subtracts the first random value (Z1), and subtracts the second random value (Z2) from the previous tapping temperature correction constant (K), unless it is within the second target temperature (Y2 ° C). Storing the new tapping water temperature correction constant (K) as a value; Then determining whether the stored tapping water temperature correction constant K is smaller than a minimum value; Judging whether the valve opening degree adjustment frequency (M) is greater than or equal to the target recovery value if the stored tapping water temperature correction constant (K) is not smaller than the minimum value as a result of the determination; Determining whether the value is "1" when the valve opening degree adjustment frequency (M) is not greater than or equal to the target recovery value; If the valve opening adjustment number (M) is "1", the average value of the return temperatures of each room stored in the predetermined place (B) is obtained, and the new tapping water temperature correction constant (K) is subtracted from the average value. Calculating a tapping temperature (Tout) of the heat source or the boiler through and adjusting the valve opening amount of each room to a value converted through a predetermined first valve opening adjustment type; If the valve opening adjustment number (M) is not "1", the average value of the return temperatures of each room stored in the designated place (B) is obtained, and the new tapping water temperature correction constant (K) is subtracted from the average value. Calculating a tapping temperature (Tout) of the heat source or the boiler through and then adjusting the valve opening amount of each room to a value converted through a predetermined second valve opening adjustment type; When the valve opening amount of each room is adjusted as described above, the valve opening adjustment number (M) is incremented by "1", and the value is stored as a new valve opening adjustment number (M), and then the process returns to the first step; Characterized in that.

On the other hand, as a result of determining whether the heating "off" or the heating "on" signal is input to any of the room cones that were previously in the heating "on" or heating "off" state, there is a change signal input of the previous state, or It is determined whether the tapping water temperature correction constant (K) is smaller than the minimum value. If it is smaller than the minimum value or the valve opening adjustment number (M) is greater than or equal to the target recovery value, the result is greater than or equal to the current heating "on" condition. Opening the valves in all rooms 100%; Then starting a count of a second time; Determining whether the second time has elapsed, and if the second time has elapsed, returning to the first step; As a result of the above determination, if the second time has not elapsed, it is determined whether the heating “off” or heating “on” signal is input to any of the room cones that were previously in the heating “on” or heating “off” state, and the previous state. If no change signal (i.e., heating "off" or "on" signal) is inputted, return to the previous step of determining whether the second time has elapsed, and if a change signal of the previous state is inputted, the current heating "on" condition The method further comprises the step of returning to the step of opening 100% of the valves in all rooms.

At this time, the heating "on" signal is transmitted from the room cone, the room temperature is lower than the user's heating set temperature, or when the user presses the heating "on" switch or the heating valve "on" set in each room "When the time is characterized by any of the states.

In addition, the 1st time t1 set by the 1st timer not shown is set to 1-3 minutes which is sufficient time for all the return water temperature difference of each room which has a heating "on" state to reach a predetermined saturation temperature, respectively. It features.

In addition, the predetermined saturation judgment temperature range (± X ℃) is the difference in the return temperature of each room stored in the predetermined place (B) after the first time from the return temperature of each room stored in the predetermined place (A) before the first time coefficient It is characterized by setting so that the absolute value of may become +/- 1 degreeC to +/- 3 degreeC.

In addition, the first target temperature Y1 ° C determined above is set to 5-7 ° C, and the second target temperature Y2 ° C specified is set to 10-12 ° C.

The tapping temperature correction constant K stored in the controller is set to 15-20, but the tapping temperature correction constant K is set to 20.

In addition, the second target temperature (Y2 ° C.) in which the result of subtracting the minimum value from the maximum value among the return temperatures of each room is determined, and then the first predetermined random value Z1 subtracted from the previous tapping temperature correction constant K is 1 or 2. The predetermined second random value Z2 which is not within the second target temperature (Y2 ° C.) and subtracted from the previous tapping temperature correction constant K is 3 or 4.

And, the target recovery value for the valve opening control number (M) is enough to reach the equilibrium temperature of each return temperature for all rooms when heating by repeatedly regulating the valve of each room having the heating "on" state. It is characterized in that 4 to 6 circuits to be set.

On the other hand, the first valve opening degree adjustment = {(heat source or boiler tapping temperature (Tout)-the return temperature of the room to set) / (heat source or boiler tapping temperature (Tout)-the return temperature of the room with the lowest saturated return temperature)} X 100 (However, the tapping temperature (Tout) of the boiler is a result obtained by subtracting the new tapping temperature correction constant (K) value from the average value of the return temperature of each room stored in the predetermined place (B)).

Also, the second valve opening degree can be adjusted = {(heat source or boiler tapping temperature (Tout)-the return temperature of the room to be set) / (heat source or boiler tapping temperature (Tout)-the return temperature of the room with the lowest saturated return temperature)} X set It is characterized in that the valve opening amount (%) in the previous valve opening control amount (M) of the room (where, the tapping temperature (Tout) of the boiler is the average value of the return temperature of each room stored in the predetermined place (B)) Minus the new tapping temperature correction constant (K).

Further, the second time t2 set by the second timer, not shown above, is sufficient for all the return temperatures of each room having the heating " on " state to reach the saturation temperature (for example, 4-7 ° C). The time is set to 3-7 minutes.

As described above, according to the method of the present invention, the heating imbalance problem caused by the pipe length or the external environmental conditions in each heating system is measured by measuring the return temperature of each room and calculating the tapping temperature by using their average value and tapping temperature correction constant. Then, by using them, the opening amounts of the valves are calculated to proportionally control the amount of heat supplied to each room. By maintaining the floor temperature uniformly and rapidly distributing and supplying the heat required by each heating pipe, the heating temperature of each room can be reached at the equilibrium state quickly, which can greatly reduce heating efficiency and energy. Flow to various installation environments without setting separate return temperature or other operation It is a very useful invention such that the length of pipe can be inferred and the amount of heat supplied to each room can be proportionally controlled, thereby greatly increasing the convenience of installing a heat source or a boiler including a district heating system.

1 is a schematic overall block diagram of a room heating system to which the method of the present invention is applied.
2 is a flowchart for explaining the method of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a schematic overall block diagram of a room heating system to which the present invention is applied, and FIG. 2 shows a flowchart for explaining the present invention.

First, each room heating system to which the method of the present invention is applied includes a room controller 2 including a heat source or a boiler 1 including a district heating system, a storage device such as first and second timers and an EEPROM, and the like. Each room is equipped with an indoor temperature detection sensor 31 and detects the heating return temperature passing through several room cones 3 installed in each room, several valves 4 for controlling the heating water in each room, and valves 4 in each room. Several heating return temperature detection sensors 6 and several valve drivers 5 for controlling the opening and closing of the valves 4 under the control of the controller 2.

In the controller 2 of each heating system having such a configuration, when a heating " on " signal is transmitted from any one of all rooms in which the room cones 3 are normally installed, the valve connected to the piping of the room ( 4) Opening and heating, detecting the return temperature of each room in which the valve 4 is opened, and not shown, but a specific place in a storage device such as an EEPROM installed in the controller 2, i.e., a predetermined place It is stored in (A) (S1).

Subsequently, the controller 2 operates a first timer (not shown) embedded in the controller 2 and then continues counting until the first time t1 determined by the first timer elapses (S2).

At this time, the first time (t1) in the present invention was set to 1-3 minutes obtained through the test in a time sufficient to reach the saturation temperature of each of the return temperature of each room having a heating "on" state.

As a result of counting the first time t1 as described above, when the first time elapses, the return temperature of each room having the valve open state is detected and stored in a predetermined place B of the storage device such as EEPROM as described above. It is stored (S3).

Thereafter, the controller 2 detects the first time t1 before the counting time and detects it after the first time t1 with respect to the return temperature of each room stored in the predetermined place A. The difference in the return temperature of each room is calculated for each room to determine whether the difference in return temperature of all rooms is within a predetermined saturation judgment temperature range (± X ° C.) (S4).

At this time, the predetermined saturation determination temperature range (± X ℃) is a predetermined place (B) after the first time (t1) has elapsed at the return temperature of each room stored in the predetermined place (A) before the first time (t1) coefficient ) Was set to a value obtained through the test so that the absolute value of the difference in return temperature stored in each room is ± 1 ℃ to ± 3 ℃.

In addition, if the difference in return temperature of all rooms is within the determined saturation judgment temperature range (± X ° C), the minimum value (Tmin) at the return temperature of the room indicating the maximum value (Tmax) among the return temperatures of each room stored in the designated place (B). It is determined whether the value obtained by subtracting the return temperature of the room indicating the temperature is within the predetermined first target temperature (Y1 ° C.) or less, and if so, the user returns to the initial stage because the target heating is desired (S5).

However, if it is determined in step S4 that the difference in return temperature of all rooms is equal to or higher than the determined saturation judgment temperature range (± X ° C.), heating at any of the room cones that were previously in the heating “on” or heating “off” state It is determined whether the "off" or heating "on" signal is input (S6), and if the change signal of the previous state (that is, the heating "off" or "on" signal) is not input, the coefficient of the initial first time t1 is determined. The process returns to the starting step S2 and repeats the subsequent steps.

At this time, the first target temperature (Y1 ℃) determined above can be set to any value according to the capacity of the heat source or the boiler or the user's taste, etc., in the present invention it was set to 5-7 ℃.

On the other hand, if the value is not within the first target temperature (Y1 ℃) as a result of subtracting the minimum value from the maximum value of the return temperature of each room stored in the place (B) determined in the step (S5) again the second target temperature (Y2) ℃) is determined within (S7), the first target temperature (Y1 ℃) is also set to any value according to the capacity of the heat source or boiler or the user's preference, etc., in the present invention 10-12 ℃ Set to.

As a result of determining whether the value obtained by subtracting the minimum value from the maximum value among the return temperatures of each room stored in the predetermined place B is within the predetermined second target temperature (Y2 ° C.), if the temperature is within the temperature (ie Y2 ° C.), the heat source or the boiler The first arbitrary value Z1 is subtracted from the previous tapping temperature correction constant K stored in the controller 2 for the tapping temperature Tout of (1) (S8), and the second target temperature Y2 ° C. If not within (i.e., higher), the new tapping value stored in the EEPROM in the controller 2 after each result value is subtracted from the previous tapping temperature correction constant K by subtracting the second random value Z2 (S9). The temperature correction constant (K) value is stored (S10).

At this time, the tapping temperature correction constant (K) value stored in the EEPROM, etc. in the controller 2 is a value obtained through an experiment, and in the present invention, the most preferable value is set to 15-20, but the first tapping temperature correction constant ( K) value was set to 20.

In addition, the second target temperature (Y2 ° C.) in which the result of subtracting the minimum value from the maximum value among the return temperatures of each room is determined, and then the first predetermined random value Z1 subtracted from the previous tapping temperature correction constant (K) is 1 or 2. Set, and the predetermined second random value Z2 subtracted from the previous tapping temperature correction constant K is not within the second target temperature (Y2 ° C) (ie, higher than the second target temperature (Y2 ° C)). Or set to 4.

In this way, when the new tapping temperature correction constant K is obtained, the controller 2 has the lowest value among 15-20 which is the tapping temperature correction constant K stored in the EEPROM or the like. (I.e., less than 15) is determined (S11).

As a result of the above determination, if the stored tapping temperature correction constant K is not smaller than the minimum value (that is, larger than 15), the valve opening adjustment time M set by the user and stored in the EEPROM in the controller 2 is the target. It is determined whether the value is greater than or equal to the recovery value (S12).

At this time, the target recovery value for the valve opening control amount (M) is to go through the control of the valve of each room having a heating "on" state repeatedly when heating the return temperature of each room to the equilibrium temperature Sufficient value was set to 4-6 times in the present invention to the value obtained through the test.

As a result of the determination in the step S12, if the valve opening adjustment number M is not greater than or equal to the target recovery value (i.e., less than 4-6), the value is " 1 " Recognition) (S13).

As a result of the above judgment, when the valve opening adjustment number M is "1", that is, when the valve opening adjustment is first performed, the average value of the return temperatures of the respective rooms stored in the predetermined place B is obtained and the new value is obtained from the average value. Calculate the tapping temperature (Tout) of the heat source or boiler (1) by subtracting the tapping temperature correction constant (K) value (i.e., average value of return temperature of all heated "on" rooms) (%) Is adjusted to the value converted through the predetermined first valve opening degree adjustment type (S14).

At this time, in the present invention, the first valve opening degree adjustment type applied when the valve opening degree adjustment number (M) = "1" is {(heat source or boiler tapping temperature (Tout)-return temperature of the room to be set) / (heat source or Boiler tapping temperature (Tout)-the return temperature of the room with the lowest saturated return temperature)} X 100%.

For example, the tapping temperature (Tout) of the heat source or boiler (1) was calculated by subtracting the tapping temperature correction constant (K) from the average return temperature of all the heated “on” rooms, whereas the tapping temperature (Tout) of the heat source or boiler 1 was 70 ° C. Assuming the return temperature in the room where the return temperature is 50 ° C and the lowest saturated return temperature is 30 ° C, in contrast to the first valve opening adjustment, {(70-50) / (70-30)} X 100% = 50 It becomes%.

That is, the opening amount (%) for the valve of the room having a return temperature of 50 ℃ is the longest pipe length is adjusted to 50% compared to the valve opening amount of the room having the lowest return temperature having an opening amount of up to 100%.

On the other hand, if the valve opening degree adjustment frequency (M) is not "1" (that is, larger than 1 but smaller than the maximum value) as determined in the step S13, as described above, the position B previously determined before opening the valve amount is cut. ), And calculate the tapping temperature (Tout) of the heat source or the boiler by subtracting the new tapping temperature correction constant (K) from the average value, and then the valve opening amount (% ) Is adjusted to a value converted through the predetermined second valve opening degree adjustment (S15).

As described above, in the present invention, the second valve opening degree adjustment type which is activated when the valve opening degree adjustment number (M) ≠ "1" is {(heat source or boiler tapping temperature (Tout)-return temperature of the room to be set) / (heat source or boiler Tout-the return temperature of the room with the lowest saturated return temperature)} X Designed as the valve opening amount (%) at the previous valve opening control number (M) of the room to be set.

As shown in the above example, when the valve opening degree adjustment frequency (M) ≠ "0", tapping of the heat source or the boiler (1) is performed by deducting the tapping temperature correction constant (K) from the average return temperature of all rooms that are also heated "on". As a result of calculating the temperature (Tout), it is 70 ℃, whereas it is assumed that the return temperature of the room to be set is 50 ° C and the return temperature of the room with the lowest saturated return temperature is 30 ° C. Looking at {(70-50) / (70-30)} X 50% = 25%.

That is, the opening amount (%) for the valve of the room having a return temperature of 50 ° C. in the valve opening control number (M) ≠ 0 is the lowest return temperature having a maximum opening amount of 100% due to the longest pipe length. The valve opening of the room with the valve is adjusted to 25%.

In the controller 2 which automatically adjusts the valve opening amount of each room to the value obtained through the first and second valve opening adjustments, the valve opening adjustment number M is incremented by " 1 " (S16). The value is stored as a new valve opening adjustment number M (S17), and then the flow returns to the initial step S1.

On the other hand, as a result of determining whether the heating "off" or the heating "on" signal is input to any one of the room cones that were in the heating "on" or heating "off" state, the change signal input of the previous state is present. (I.e. Yes in S6), or judging whether the tapping temperature correction constant (K) is smaller than the minimum value, or smaller than the minimum value (ie, Yes in S11), or the valve opening adjustment frequency (M) is greater than the target recovery value. If the result of the determination is equal to or greater than (i.e., Yes in S12), 100% of the valves of all rooms in the current heating " on " condition are opened (S18).

Subsequently, in the controller 2, although not illustrated, the controller 2 operates a second timer embedded therein to start counting the predetermined second time t2 (S19), and then determine whether the second time t2 has elapsed (S20). If the second time t2 has elapsed, the process returns to the first step S1.

However, as a result of the above judgment, if the second time t2 is not in the elapsed state (ie, the state before the second time has elapsed), the room cone 3 which was in the heating "on" or heating "off" state before It is determined whether any one of the heating " off " or heating " on " signals is input, so that if the change signal of the previous state (that is, the heating " off " or " on " signal) is not input, the second time t2 Return to the previous step (S20) of judging whether this has elapsed, and if the change signal of the previous state is inputted, returns to the step (S18) of opening 100% of the valves in all the rooms in the current heating "on" condition and then proceeds to the subsequent step. Will be repeated.

At this time, the second time (t2) in the present invention 1- 1 obtained through the test in a time sufficient for all the return temperature of each room having a heating "on" state to reach the saturation temperature (for example, 4-7 ℃) Set to 3 minutes.

As described above, the present invention measures the return temperature of each room before and after the first predetermined time, and when the difference is within a predetermined temperature, obtains an average value for the return temperature of each room and uses the set tapping temperature correction constant to determine the heat source or boiler. Calculate (outflow) the temperature of tapping and then prepare it for the first and second valve opening adjustments (ie, the heat source or boiler tapping temperature (Tout), the return temperature of the room with the lowest return temperature and the saturated return temperature). And multiply the magnification by the predetermined magnification to calculate the opening amount adjustment value for the valves in the rooms, and to adjust the opening amount for each valve in response to the value several times (ie, 4-6 times) This provides a proportional amount of heat regardless of the size of the room and other environmental conditions, so that the floor temperature of each heated "on" room is kept even. By rapidly distributing and supplying the required heat from each heating pipe, the heating temperature of each room can be reached at equilibrium quickly, which can greatly reduce the efficiency and energy of heating. By inferring the length of the pipe fluidly in various installation environments without manipulation and controlling the amount of heat supplied to each room proportionately, the convenience of installing a heat source or a boiler including a district heating system can be greatly increased.

It should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
