Abstract: A circuit for driving a gas-discharge device wherein discharge cells (120) each have a column electrode (28) and a segment electrode (26), includes a transformer (80) whose secondary winding (86) provides operating voltages for application to the electrodes. In operation, the secondary winding (86) is arranged during first time intervals to supply to the column electrodes (28) a first potential while a reference potential is applied to the segment electrodes (26). During second time intervals, the secondary winding (86) is arranged to supply to selected segment electrodes (26) a second potential, the reference potential being applied to selected column electrodes (28). Cells including selected column and segment electrodes are repeatedly ignited. A voltage regulator circuit (196) is coupled to the secondary winding (86).

Abstract: Increasing the speed and hit ratio for data fetches in data processing systems is essential. Increased data fetch speed normally results from using a fast cache memory with a slower main memory. The hit ratio for such fetches can be increased by using cache memory (26') which incorporates data buffer (34') that stores blocks of data that are varied in size and a set associative memory as index (32') which stores block addresses for main memory (14), which addresses are associated with the data blocks stored in buffer (34'). The block sizes are varied by selectively inhibiting address bits provided to an input (40') of the index (32') by address inhibit circuit (54) in response to information stored in block size register (54). Such block size information is also provided to a fetch generate counter (60') and a fetch return counter (62') for controlling the number of words transferred as a block from main memory (14) to cache memory (26').

Abstract: A system for loading a DC multiline plasma charge transfer device (26) and for holding charges applied thereto. Each line of the device includes input (1) and transfer electrodes (20) positioned on opposing walls which define a channel (16) confining an ionizable medium. The transfer electrodes (20) comprise adjacent groups of four electrodes (A, B, C, D, ) with two (20B, 20D) driven in common with like electrodes of all other lines, and with timing of pulses applied by common drivers being regular and constant. A common driver (56) is also utilized for the input electrodes (1) of each line while logic control is applied to the input driver and to the other transfer electrodes (20A, 20C) for each line. With this system and with a minimum of drive electronics, the charges may be shifted to a desired location and in desired patterns along the length of the device. The charges may be held at the desired location by circulating the charges between a set of electrodes at the desired holding location including two commonly driven electrodes (20B, 20D). Additional input can be achieved on any line while maintaining prior input.

Abstract: In order to compensate for drift of the null point of a measuring device (12), particularly a signature verification device, an analog measurement signal on line (16) is compared in an operational amplifier (18) with a compensating signal from a digital to analog converter (32) to provide a comparison output signal on line (22), which represents a signal compensated for drift. The comparison output signal is fed via an analog to digital converter (24) to a microcomputer (28) for further processing. The microcomputer is arranged to compute a value of compensating signal which accurately compensates for drift of the null point of the measuring device, and to this end stores a prior value of the comparison output signal with the measuring device in a null point condition and compares this with the current value of the comparison output signal with the measuring device in a null point condition. Depending on the result of such comparison, the stored value is modified. This operation is repeated until the comparison output signal attains a zero value, the stored value then representing a compensating value which is applied to the digital to analog converter (32) for providing a compensating signal for subsequent use of the measuring device (12).

Abstract: An apparatus for generating pulses for both character and individual "dot" strobing, as for example, in matrix printers. The apparatus includes a first stationary synchronization track (32) and a co-operating first movable synchronization track (40), to move with the matrix printer, for generating the start of character pulses and a second stationary synchronization track (54) and a second co-operating second movable synchronization track (56) to move with the matrix printer, for generating individual "dot" pulses of a character to produce vertically aligned characters in a bi-directional printer. The first synchronization tracks (32, 40) are designed to produce pulses having narrow rise and fall slopes for accurate character location and the second synchronization tracks (54, 56) are designed to produce pulses having gradual rise and fall slopes to provide for adjustment of the individual "dot" pulses for bi-directional printing.

Abstract: A two piece hand-manipulated variable fit fastener comprises an elongated fastener member (20) having a reduced axially extending portion permitting the fastener member to be folded on itself prior to being inserted through or withdrawn from aligned apertures (28) located in a pair of mating work pieces (30, 32) and a retainer element (26) having a plurality of locking surfaces, the retainer element being slidably mounted on the fastener member. After insertion through the aligned apertures in the work pieces, the fastener member (20) is unfolded to a position engaging one of the locking surfaces in the retainer element to lock the fastener member in a selected unfolded position depending on the diameter of the apertures (28). The positioning of the fastener member in the unfolded position also allows pairs of end shoulder portions (22) to engage one of the work pieces and the retainer element (26) to fasten the work pieces together.
