Title: Improvements in or relating to shift register circuits employing transistors
Inventor: WILLIAMS FREDERICK CALLAND
IPC: G11C19/28
Filed: 1953-05-15
Abstract: 760,919. Electric digital-data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 14, 1964 [May 15, 1953], No. 13655/53. Class 106 (1). In an electronic shift register in which each stage comprises a transistor, means connected between the collector electrode of the transistor of a first stage and the emitter electrode of the transistor of the succeeding stage determine whether the latter transistor is switched " on " in response to a shift signal applied to the emitter electrodes of the transistors, control signals being applied to the base electrodes. In the shift register shown, each stage comprises a transistor circuit as described in Specification 747,606, predetermined currents being supplied to the collector and base electrodes. The collector electrode of transistor T<SP>1</SP> is connected to the emitter of the succeeding transistor T<SP>2</SP> through a memory circuit comprising crystal. or other diodes D<SP>1</SP>/<SP>2</SP>, D<SP>2</SP>/<SP>2</SP>, resistor R<SP>2</SP>/<SP>2</SP> and con. denser C<SP>1</SP>/<SP>2</SP> (the suffix " 2 " denoting the number of the stage). Positive 0.25 Ás. shift pulses applied from terminal I to condensers, such as C<SP>1</SP>/<SP>1</SP>, C<SP>1</SP>/<SP>2</SP>, for all stages, coincide at leading edges with negative 0.5 Ás. clock pulses applied, e.g., from associated computer control circuits, to diodes D<SP>4</SP>/<SP>1</SP>, D<SP>4</SP>/<SP>2</SP>, &c. in the base electrode circuits of the transistors. In operation, a binary " 1 " is stored between shift pulses by a charge on a condenser in the corresponding memory circuit. If, e.g., condenser C<SP>1</SP>/<SP>2</SP> is charged, the next shift pulse will raise the potential of point A and thus of the emitter of T<SP>2</SP> above the resting level of Ov, while, simultaneously, the base electrode potential is allowed to fall to - 2v by the clock pulse; T<SP>2</SP> is therefore switched " on " and the raised collector potential charges the condenser in the succeeding memory circuit (not shown). At the end of the clock pulse, T<SP>2</SP> is switched " off." In another form, the transistors remain switched " on " between shifts to register " 1 ", positive 3 Ás. clock pulses applied to the diodes D<SP>4</SP>/<SP>1</SP>, D<SP>4</SP>/<SP>2</SP> switch all the transistors off, and shift pulses applied immediately after the clock pulses switch " on " the succeeding transistors. A binary number may be entered serially or in parallel into the register.

Filed: 1962-04-10
Abstract: 934,026. Extruding; forging. TRANS ENERGY CORPORATION. April 10, 1962 [Sept. 13, 1961], No. 13796/62. Class 83 (4). An impact press has a frame 20, Fig. 1, carrying a support 24 for a workpiece 60 to be deformed, and a reciprocating ram 46 which is driven on its working stroke by gas compressed in a sealed chamber 36 during the return stroke which is effected by a piston and cylinder mechanism 72, 88, the ram being held in its raised position between strokes and then released by a latch 108. In this embodiment the frame 20 is of one-piece construction and includes a bed 24 supporting a die 56 and a cylinder 28 which co-operates with a tubular extension 50 of the ram 46 to form the compression chamber which has a filling and check valve 44. The ram head 48 is of square shape in plan, Fig. 3 (not shown), and its corners slide along vertical guides 66, 68. The ram is raised by hydraulic cylinders 88, 90 reciprocable over stationary pistons 72, 74 and carrying latches 108, 110 which engage beneath the ram. During the upstroke the gas in chamber 36 is compressed to 2000 p.s.i. and the latches retain the ram in its upper position until they are released by fluid, preferably hydraulic, cylinders 126, 128, containing spring-loaded pistons, Fig. 4 (not shown). After release of the ram, the cylinders 88, 90 are moved downwardly by hydraulic fluid supplied through ducts 96, 104 until the latches 108, 110 snap over the ram. The impact on bed 24 is cushioned by a rubber pad 34. Workpiece 60 is deformed by backward extrusion into a dish shape 62, Fig. 15 (not shown). An electrically controlled hydraulic circuit is described, Fig. 8 (not shown), including limit switches which cause the ram to be raised automatically. In a modification, Fig. 16 (not shown), the compression chamber of cylinder 28 is enlarged whereby the gas pressure remains substantially constant. In another embodiment, Fig. 9, the latches 108a, 110a are elongated and their operating cylinders 126a, 128a are mounted on the stationary frame 20 which is of multiple part construction. Shock absorbers 34a are provided for the bed. The ram 46a slides over an extension 236 of the head 28a and has a fluid seal 52a and annular grooves 238 which tend to retain pressure gas so as to centre the ram and minimise friction. In another embodiment, Fig. 12, the ram 46b is raised by plungers 268 in the bed 24b which are biased downwardly by gas pressure admitted through ports 276 and are raised by hydraulic pressure admitted through ports 270. The latches 108b, 110b are pivoted at 112b, 114b to the stationary frame and are operated by a common fluid cylinder 260.
