Decryption of a plurality of simultaneously received, randomly phased signals is realized by employing a single data encryption standard module in a time shared manner. A plurality of process state counters, each of which is associated with a received signal, are employed to direct operations of the decryptor on a time shared basis. These operations include the generation on a time shared basis of so-called plain text data for each received signal, generation of corresponding encryption requests...

A common electrolyte manifold battery that includes at least one module having a plurality of cells, at least one common electrolyte manifold traversing the cells for transporting a low conductivity electrolyte, an anode and a cathode. The one module includes a collector plate, the collector plate has an end exposed to the common electrolyte manifold, and one of the cells. The one cell comprises a first bipolar plate, positioned in parallel with the collector plate, that has an end proximal to t...

An insulated common strip for selectively coupling electrical components to the circuits of a printed wiring card. A self-tapping screw is used to close an electrical path between first and second pretensioned spring conductors mounted on an insulating block and coupled to the printed circuits.

Methods and apparatus relating to either point-to-point or contouring control of the movable members of a machine tool, wherein two or more of such members are movable along a common axis relative to a base. In order to accept end-point commands numerically expressed in part coordinate along the common axis with reference to an origin in fixed relation to a workpiece or part mounted on the first such member, even though the servo controls or actual positioning operations can only act to bring th...

An arrangement in a communication switching system for providing wideband signal equalization on a common basis to a plurality of communication lines. Upon selecting a path from a communication line through the switching system, a common control retrieves information related to the length of the communication line. This information is utilized to condition a variable attenuator in the selected path to attenuate signals conveyed over the line to a predetermined level. The attenuated signals are t...

A wiring module has a plurality of sockets within an insulating case. A grounding stud suitable for mounting the module on a metal support has an end which extends through the case, a flange that abuts the outside of the case and a screw which clamps some of the socket structure against the inside of the case.

A vending machine includes a plurality of selection switches corresponding to a plurality of items to be sold respectively, and in response to insertion of coins and the subsequent operation of any of selection switches, the item corresponding to the selection switch is vended. A RAM is installed associatedly with a microcomputer, and this RAM contains memory areas for storing the sales quantity and the sales amount on item basis, and these data are renewed at every vending. The RAM further cont...

A common coil device in a dryer control circuit usable as an electromagnetic device for developing functions of both a motor and a relay. The relay function is utilized as a circuit continuity function which is normally provided as a shunt to a momentarily operated starting push button, and the motor function is utilized as a timer for intermittent pulsing of the dryer drive motor during an antiwrinkle cycle.

A common mode detector (10) for producing an output voltage (VA+VB)/2 in response to input voltages VA and VB contains a pair of MOS transistors (MA and MB) connected in series between a pair of input terminals A and B to which the input voltages (VA and VB) are to be applied. A separate feedback path runs from each input terminal (A, B) through a separate load device (LA2, LB2) to a gate control terminal of the respective MOS transistor (MA, MB), and a separate other feedback path runs from eac...

A common controlled facsimile system which has a plurality of simple facsimile terminals commonly controlled by a single control system. Each facsimile terminal has means (21) for converting picture data to electrical signals, and means (22) for reproducing picture images from said electrical signals. The common control system has a disk memory (39) with large capacity. A picture image generated by a first facsimile terminal is first stored in the disk (39) of the common control system, and late...
