(Cl. 235-ol) 'lhe present invention relates to a number transmitting arrangement, and more particularly to an arrangement for transmitting information representing a multi-order number to a remote station.

Gne object of the present invention is to provide an arrangement permitting simultaneous transmission of a plurality of electric impulses respectively representing digits of a plurality of orders.

Another object of the present invention is to provide a transmitting arrangement capable of simultaneous transmission of several impulses with a minimum of electric connections.

Another object of the present invention is to provide a compact transmitting arrangement which can be built into a conventional calculator.

Another object of the present invention is to provide a reliably and rapidly operating transmitting arrangement for connecting at least two calculators so that a number introduced into one of the calculators is transmitted to the other calculator, and stored in the counter mechanism of the same.

With these objects in View, a transmitting arrangement according to one embodiment of the present invention comprises a set of first conductors; a set of second conductors which preferably cross the first conductors to form with the same crossing points; a set of electric actuators, which are respectively connected to the first conductors; a set of voltage sources respectively connected to the second conductors and to the actuators; and means for connecting selected first conductors to selected second conductors, preferably by switches or connectors disposed at the crossing points of the first and second conductors.

The conductors of one set represent the orders of a number, and the conductors of the other set represent digits. Consequently, the crossing points between the conductors represent digits in their respective orders. When the first and second conductors are connected at selected crossing points, a digit and an order are thus selected, and an impulse passes from the respective voltage source to the respective correlated electromagnetic actuator independently or" the other voltage sources. In this manner, all impulses can be simultaneously transmitted to electromagnetic actuators which are l cated at a remote station to actuate the input means of a calculator simultaneously in several orders.

In the preferred embodiment of the invention, the voltage sources are constituted by a set of secondary windings of a transformer, each secondary winding being connected through a rectifier to a conductor which represents an order, and to a line connected to a group of electro-magnetic actuators, each of which is also connected. to a digitreprescnting conductor.

The novel feat-u es which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 is a perspective view illustrating a full-key calculator provided with means for transmitting and receiv- Patented Felts. 2'3, i953 log information in accordance with the present invention; and

2 is a diagram illustrating the electric circuit of an arrangement according to the present invention.

Referring now to the drawings, and more particularly to FIG. 1, a conventional full-key calculator has a keyboard q, each key of which is shown to be provided with an electro-magnetic actuator 0 having a movable actuating member r. Part of the casing of the machine is omitted to show the interior of the machine which contains a counter gear It meshing with a transfer gear i which is in meshing engagement with a rack bar It. The rack bar It is pivotally mounted in the machine, and is operated by a cam nso that a rotation of cam 11 will effect movement of the projection m on bar k to and from a lower operative position.

A matrix is mounted on an insulating plate 2, and comprises a set of first parallel conductor bars b, and a set of parallel second conductor bars a which cross conductors b at right angles. Conductors a and b are provided with bores at the crossing points, and switch pins 1 are located in these bores and are shiftable between an inoperative circuit-breaking position, and a circuit closing position in which they make contact with both conductors at the crossing point, and consequently connect the re spective crossing conductors to each other.

Bar k extends in the direction of the conductor bars a, and when the counter gear 12 is operated to represent a digit, the projection m will move along the respective conductor a until located above a switch pin 7 on the crossing point with a digit-representing conductor b. When cam It moves projection in to its operative position, the T63331- tive switch pin is shifted to its circuit-closing position, and a connection is established between the respective conductor a representing an order, and the respective conductor 1) representing a selected digit.

This operation is carried out in all orders of a number introduced into the storage means of the calculator, so that the respective number is represented in the matrix a, I), j.

A transformer having a primary winding e and a set of secondary windings d is disposed in the casing of the calculator, and the primary winding is connected to a source of alternating voltage. As also shown in PEG. 2, each secondary winding :5 is connected by a wire 3 to a rectifier 0 whose other terminal is connected by a Wire 4 to a correlated conductor a. Since the conductors a are respectively associated with different orders, each secondary winding, which constitutes an independent source of voltage, is also associated with an order.

T he other ends of the secondary windings are respec tively connected by electric connections 2 to a groups G of electromagnetic actuators g, as best seen in FIG. 2, only one actuator being shown in PEG. 1, but as shown in PBS. 2, a set of groups G of actuators g is provided, only three group G of the set being shown for the sake of simplicity. The electro-magnetic actuators g are located at a remote station, for example at a second calculator. The keys of the second calculator at the remote station may be operated by the electromagnetic actuators g in the same manner as the keys of the calculator shown in FIG. 1 are operated by an electro-magnetic actuator 0.

The transmitting arrangement of the present invention operates in the following manner: A numerical value introduced into the counter mechanism of the calculator is transmitted by gear 1' to the rack bar k so that the projection m assumes a position located over the switch pin 1 at the crossing point with the conductor b associated with the respective digit. When cam n actuates rack bar 1:, switch pin is shifted to its circuit-closing position connecting the respective two conductors a and b at the crossing point. In this manner, a circuit is closed, and an impulse passes from the respective secondary winding d, rectifier c, connection 4, "the respective conductor a of the respective order, switch pin 7, the respective conductor b associated with the introduced digit, the-electromagnetic actuator g connected to the respective conductor :5, and through line 2 back to the secondary winding (1.

In accordance with the preferred embodiment of the invention, several second windings provide independently of each other the voltages for the group of actuators. Since a group digit-representing actuators is connected to each independent voltage source (I, a circuit can be completed in each order, so that impulses representing numbers can be transmitted in all orders simultaneously, resulting in a very rapid transmission of a multi-order number between two calculators.

The transmitting calculator may also receive impulses from a remote station, and be actuated by electr c-magnetic actuators 0, only one of which is shown in FIG. 1

It will be understood that each of the elements described above, or two or more together, may also find a useful application in oter types of number transmitting arrangements differing from the types described above.

While the invention has been illustrated and described as embodied in a transmitting arrangement providing an independent voltage source for each order of a calculator, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any 'way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specfic aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
