 Electronic chess clocks work as follows.

 Switch 1 sets the control clock 2 "white", the control clock 3 "black", the game clock 4 "white" and the game clock 5 "black" in the "initial" position, while on the control clock the readings of indicators 6, counters 7 are "white" and the readings of indicators 8 counters 9 “black”, on the game clock the readings of indicators 10 counters 11 “white” and indicators 12, counters 13 “black” are respectively set to “0”, while at the same time counter 14 controls the number of moves made “black” is given to the standby position and on the indicator 15 of the counter 16 a value is set that is not equal to zero, on the counter 17 controls the number of moves made "white", the indicator 18 of the counter 19 is set to "0".

 The switch 20, having three positions: "Neutral", "Set the control time" "white", "Set the control time" black "at the control clock 2" white "and at the control clock 3" black "using a source of 21 reference pulse signals through the first and second match patterns 22 and 23, through the first and second 24 and 25 match patterns, respectively, the time allotted to the game for each player is set. The time is set in the range from units of seconds to 24 hours inclusive and is controlled by indicators 6 sources 7 control hours 2 "white" and indicators 8 counters 9 control hours 3 "black". Simultaneously with the outputs of the counters 7 control hours 2 "white" and the counters 9 control hours 3 "black" information about a given time in the form of logical codes is fed to the inputs of the first device 26 memory and the second device 27 memory, respectively. The stored information from the outputs of the first memory device and the second memory device 27 in the form of logical codes is supplied to the first inputs of the first comparison device 28 and the second comparison device 29, respectively. After setting the monitoring time, the switch 20 is set to “neutral”.

 The game starts by pressing the button located on the "black" side, switch 30 (having three positions: "Neutral", "Start White", "Start Black") to the "Start White" position, with "Log.1" from the first exit the switch 30 is fed to the input of the counter 16, which is included in the counter 14 of the control of the number of moves made "black", setting it in the "initial" position (indicator 15 displays zeros), and to the input of the third match circuit of the game clock 4 "white". The appearance of the third “Log.1” at the input of the coincidence circuit 31 (before that, its inputs “Log.1” came from the output of the signaling device 32 and the source 21 of the reference pulse signals at the moments of appearance of pulse signals at its output with a period at the moment of appearance on it the output of pulse signals with a period T of 0.01 s) allows the passage of signals from the source 21 of the reference pulse signals to the input of the counters 11, the game clock 4 "white" and the counters 7 of the control clock 2 "white", thereby starting the countdown of the time spent on first-step equipment "And taking the residual count time from a predetermined reference time.

 Having made the first move on the chessboard, playing “white” by pressing a button (located structurally on the side of the “white” clock) sets the switch 30 to the “Start black” position, while “Log.1” from the second output of this switch goes to the input of the counter 19 included in the counter 17 to control the number of moves made "white", setting the number 18 on its indicator 18, and on the input of the fourth coincidence circuit 32, allowing the passage of signals from the source 21 of the reference pulse signals to the input of the counters 13 of the game clock 5 "black" and counters nine control hours of 3 “blacks”, fixing the time spent by “blacks” on thinking over the first move and counting the residual from a given control time. The switch 30 is turned to the “Start Black” position on its first output, “Start White”, the signal value is from “Log. 1” to the value “Log.0”, thereby the third coincidence circuit 31 prohibits the passage of signals from the source 21 of the reference pulse signals to the input counters 11 and 7, thus turning off the game clock 4 and the control clock 2 "white".

 Having made the first move on the chessboard, playing “black” at the touch of a button, sets switch 30 to the “Start white” position, starting the game clock 4 “white”, and the time spent on thinking about the second move starts, simultaneously on the indicator 15 of counter 16, counter 14 controls the number of moves made "black" displays the number one, and the game clock 5 "black" stop counting.

 The chess clock operation process described for the first moves is similarly repeated for subsequent ones, while the elapsed time for thinking about each move is summed up with the subsequent one and is sent to the inputs of the first comparison device 28 as game codes from the game clock 4 and from the game clock 28 5 hours of "black" is fed to the inputs of the second device 29 comparison. When the “white” or “black” time is reached equal to the initial value set on the control clock of “white” or “black” and recorded in the memory devices 26 and 27, the command codes on the first and second inputs of the devices 28 or 29 match and at the moment of coincidence, a signal appears on the output of this device, which is fed to the second input of the anti-coincidence circuits 33 or 34 and then goes to the first or second input of the alarm device 35 from the output. The alarm device 35 is triggered, and a scale will be displayed with the inscription “Your time is up” on the other side of the “white” or “black” watch, which has run out of time, and the sound of intermittent signals will begin. At the time of the appearance of light and sound alarms at the output of the alarm device 35, the signal "Log.1" is changed to a signal "Log. 0", which will close the matching circuits 31 and 32, and thereby stop the game clock 4 "white" and game clock 5 “black”, control clock 2 “white” and control clock 3 “black”, while information is stored on the indicators of the game and control clock “white” and “black”. So on the indicators of the game clock, which has run out of time, the time equal to the set control time set before the start of the game and recorded in the memory of the memory device is displayed, and on the indicators of the control clock, which have run out of time, the value of the remaining time is displayed, which should be equal to to zero.

 At the same time, during the game, until the end of the set control time, the sound and light alarm device 35 is provided for when forty moves, sixty moves, and also when the internal voltage level is reduced at the predetermined time, is not made “white” or “black” power supply to a threshold value at which the operation of the clock becomes impossible and replacement of electronic chess clocks with others is required.

 The control functions for the number of moves made at a predetermined time are performed by the first code signal generator 36 for white and the second code signal generator 37 for black. The first input of the first generator 36 code signals receives pulses from the output of the third match circuit 31 of the game clock 4 "white", the second input signal from the output of the counter 19, which is included in the counter 17 to control the number of moves made "white". The first input of the second generator 37 code signals receives pulses from the output of the fourth circuit 32 matches of the game clock 5 "black", the second input signals from the output of the counter 16, included in the counter 14 control the number of moves made "black". At the outputs of the shapers 36 and 37, the signals will appear only in those cases when, in a given period of time, signals corresponding to the arrival of the fortieth or sixtieth moves are not received at their second inputs. If the fortieth and sixtieth moves are made at the set time, the shapers do not work and the game continues. The appearance of the signal at the output of the driver 36 will trigger the anti-coincidence circuit 33 and from its output the signal is fed to the first input of the sound and light alarm device 35. The signal from the outputs of the generator 37 code signals is supplied to the first input of the fourth anti-coincidence circuit 34, it will trigger its operation, and the signal is fed to the second input of the signaling device 35. With the sound and light signaling turned on, at the same time, a signal in the form of "Log.0" (instead of "Log.1") appears on the output of device 35, which, coming to the inputs of coincidence circuits 31 and 32, causes them to be closed, while on the game and control the white and black watches retain all current information.

 The introduction of the first and second memory devices 26 and 27 into the chess clock structure allowed the use of counters 7 and 9 with indicators 6 and 8 of the control clock 2 “white” and the control clock 3 “black” as devices that perform a dual function, the initial one for installation and display typed control time and after it is recorded in the memory of the first and second memory devices 26 and 27, and then at the beginning of the game use them as counters and indicators of the remaining time. So, for example, when setting the control time allotted to the game for each chess player, two hours are allotted, but after the start of the game, after the "start" of white hours, on the indicators 6 counters 7 of the control clock 2 of the "white" the subtraction of the playing time from the control time begins , i.e. from two hours the time spent thinking by the “white” of the first move is deducted, and this happens until (if the game has ended prematurely), until the indicators 6 seconds, minutes, hours of counters 7 show zeros, the same thing happens on the control clock 3 blacks.

 The introduction into the clock circuit of the device 38 of a fixed setting of the control time allows, with one click of the button included in this device, to set the control hours 2 and 2 of "white" and "black" immediately "5 min", by the second press of the button to set the control time "30 min ", the third press of" 1 h ", etc. up to "3.5 hours" inclusive. From the outputs 1 and 2 of the device 38 for the fixed installation of the control time, signals in the form of logical codes are fed to the second outputs of the first and second anti-coincidence circuits 24 and 25, from the outputs of which the signals are fed to the inputs 2 of the counters 7 and 9 of the control clock 2 and 3 of “white” and blacks respectively.

 The watch uses batteries with a charger 40 and a threshold voltage monitoring device 41 with a light alarm indicator 42 as a source of internal power supply 39. In the case when the voltage level of the internal power source 39 decreases to a threshold value at which the operation of the clock becomes impossible, a signal is generated in the voltage control device 41, which is output from the device 41 to the input of the light alarm indicator 42, as well as to the third inputs of the circuits 33 and 34 anti-coincidences. From the output of the anti-coincidence circuits 33 and 34, the signals are fed to the first and second inputs of the alarm device 35, which triggers and stops the game and control hours of the “white” and “black” ones. At the same time, the light-alarm indicator 42 lights up, indicating that the reason for the stop of the chess clock is the low voltage of the internal power supply 39, and that it needs to be recharged.

 The technical design of electronic chess clocks is traditional, made on the basis of the existing logical and digital elemental base, containing logical elements AND, OR, counters of various constructions, including reversible decoders, memorized devices, indicators, etc. For example, as counters 7 and 9, reversible counters are used, when they are fed to the second input, the signals are summed, and when signals are received at the first input of the counters, information from the higher digits is subtracted. Thus, electronic chess clocks have a wide range of functionality compared to the well-known electronic chess clocks.
