Title: Enhancement semi-conductor amplifier
Inventor: JUN JOHN CLARK SIMS
IPC: H03K3/33
Filed: 1957-03-14
Abstract: 826,556. Electric digital-data-storage apparatus. SPERRY RAND CORPORATION. March 14, 1957, No. 8424/57. Class 106 (1). [Also in Group XL (c)] In a circuit comprising first and second diodes 18, 12, Fig. 1, of which at least one diode 12 exhibits carrier storage,. similar electrodes of the two diodes are connected together and to a source of input signals 16 with a clock pulse source 19 feeding the diode 18 and transformer T 1  coupled to the other electrode of the diode 12. The transformer core is biased to a saturated state by a current supplied to winding 24. During the negative-going waveform of the clock pulse A, diode 18 is reversely biased and no current flows in the winding 14. During the succeeding positive-going wave a small current C passes through the back resistance of diode 12 and the winding 14 but since this is insufficient to drive the core from its saturated state, no output appears across the winding 22. If, during the next negativegoing clock pulse an input pulse B is applied to the junction of the diodes 12, 18 forward current flows in diode 12, driving the core of the transformer T 1  further into the saturated region. When the input pulse ceases and the clock pulses reverse, considerable current flows in the reverse sense of diode 12 driving the core from one saturated condition to the other, Fig. 3 (not shown), to produce an output pulse D on windings 22. This output pulse is terminated by the next negative-going clock pulse which allows the bias source 25 to restore the core to its original condition. The input signal is applied over a transformer and blocking pulses E are applied to the secondary to prevent reaction on the input due to the clock pulses. A number of circuits may be connected in cascade, Fig. 4, to operate as a delay element or as a shifting register or ring counter, the clock pulse source providing two pulses C, D, operating out of phase, with blocking pulses A, B. The input pulse E produces an output F as in the first embodiment. This process is continued through the second and third stages to provide the final output pulse H. In order to allow the bias source 53 to reset the cores T 2 , T 3  and T 4  the blocking pulses A, B are arranged to have a slightly greater width than the clock or power pulses C, D so that the output pulses F, G and H are somewhat shorter than in the first embodiment. Specification 826,555, [Group XXXIX], is referred to.

Abstract: 342,584. Amusement cars. PHILLIPS, H. G. O., 2, Pattison Street, St. Kilda, Victoria, Australia. March 18, 1930, No. 8704. [Class 132 (i).] Bumpers; cars moving freely.-In an amusement car the bumper or fender ring 12 is supported at a suitable distance from the floor 2, Fig. 1, by means of a number of strong volute springs 13, each of which encloses a stem 14 that extends from the ring 12, through a guide member 15, Fig. 4, in the outer rim 11 of the floor 2, and into a recess 14a under the floor, where an additional spring 16 is anchored between the rear end of the stem and a pin 15a on the guide 15. The pin 15a projects into a longitudinal slot 15b in the stem 14, while the guide 15 and recess 14a are made of sufficient width to accommodate the lateral displacement of the stem 15 about the pin 15a as pivot, these arrangements permitting the fender 12 and stem 14 to yield both to normal and to obliquely directed impacts. Interposed between the strong springs 13 are a number of weaker springs 13a located entirely in the annular space between the fender 12 and rim 11. Motor forecarriages ; deflectable axle-ends and the like for steering.-A casing 1 is revolubly mounted on the floor 2 and carries at its lower end the axle 9, Fig. 5, of the driving wheel 4, which has two treads 4a, 4b with an intermediate gear-wheel 10 adapted to be driven from the motor shaft 3a, Fig. 1, through chain 7, shaft 5, and second chain 10b. In order to position the axle 9 to suit the length of the chains 7, 10b the bearings 9a thereof are supported in vertically adjustable blocks 24 slidable in grooves in the casing 1. The casing has a surrounding external toothed ring forming part of a gearing 29 associated with a pinion 27 at the foot of the steering column 26b, so that the driving wheel 4 is steered simultaneously with and remains substantially parallel to the front wheels 26, which are steered through gearing 28. The motor circuit is completed by depression of a foot pedal 22 against the action of a return spring 22c, contact being made between fixed and movable strips 20, 21 and the circuit including the trolley pole 17, conductor 19, strips 20, 21, conductor 23 and a collector ring 24d on the motor support.

Abstract: 1433665 Gas discharge display panels MITSUBISHI DENKI KK 27 Feb 1974 [27 Feb 1973] 8965/74 Heading H1D A plasma display panel apparatus comprises a first laminar array of substantially parallel elongate main strip electrodes 12, a second laminar array of substantially parallel elongate main strip electrodes 18, the said arrays being disposed face to face with a gas-containing discharge gap 24 therebetween and with the electrodes of one array crossed with respect to those of the other array, at least one said array being provided with auxiliary elongate strip electrodes 50 or 52 respectively adjacent to and parallel to main electrodes of the array, circuitry 36, 40 for applying to all the auxiliary electrodes a sustaining voltage for producing across the discharge gap voltage pulses of alternating polarity, electrical insulation between one array and the gas, light-transmitting electrical insulation between the other array and the gas, and circuitry for applying selectively to main electrodes of both arrays discharge-initiating or discharge-quenching voltage pulses Px, Py or Qx, Qy. The sustaining voltages are of insufficient amplitude to initiate a discharge but simultaneous application of initiating pulses Px and Py to selected main electrodes 12 and 18 results in a discharge at the cross-point 56 of the selected electrodes, together with the establishment of a region of wall charges 58. Subsequent sustaining pulses in conjunction with the reversing wall charges produce and extinguish discharges in turn at cross-points 62, 60, 64 and back to 56. This continues until extinguishing pulses Qx and Qy applied to the selected main electrodes reduce the wall charges to zero so that subsequent sustaining pulses are unable to produce a discharge. In an alternative embodiment (Figs. 7 and 9, not shown) one array of auxiliary electrodes is omitted, the operations being then effected by applying a train of bipolar pulses to the remaining auxiliary electrode array. The gas filling may be neon plus a small amount of argon or nitrogen.
