Filed: 1975-07-09
Abstract: 1509607 Matrix displays FUJITSU Ltd 9 July 1975 [9 July 1974] 28956/75 Heading G5C The display operation of a gas discharge panel with crossed conductors insulated from the gas and X electrodes connected sequentially to buses A, B, C, D; in which charges are initially shifted across the panel to selected sites; comprises applying sustain signals VC, VD to two but not all of the buses whereby discharges are continuously moved from the selected sites to adjacent sites and back again. The method whilst doubling the size of each display element keeps the operating margin during shift and display operations equal since there is always a space of 3 sites between energized sites. In a known method in which two buses are continually driven, the space is reduced to two sites. The shift signals VA. 1 .VD each comprise the same two shift pulses and an erase pulse and are also used during the display period DP. The methods can be used when the X electrodes are connected to only 3 buses and when the Y electrodes are arranged in two groups and each display element comprises 4 sites.

Abstract: 1,155,901. Amplifier circuits; amplitude modulation; dielectric amplifiers. GEORGE A. PHILBRICK RESEARCHES Inc. 30 June, 1966 [30 June, 1965], No. 29536/66. Headings H3B, H3R and H3W. In an amplifier arrangement having a single pair of matched variable capacity semiconductors 30, 32 and a single capacitor 34 connected to form a modulating network, the capacitor 34 has a value substantially twice the nominal capacity of one of the semi-conductors 30, 32, where nominal capacity is the rated value of capacity at zero D.C. bias. An oscillator signal is supplied via transformers 42, 24 together with the D.C. input at 18 to the variable capacity diodes 30, 32 so that the input D.C. modulates the oscillator signal. The output is coupled by a transformer 26 to an A.C. amplifier 16, the output of which is demodulated and may be further amplified by a D.C. amplifier. The characteristics of the diodes which are matched are the absolute capacity, that is the measured value of capacity, at a given temperature, change in capacity with temperature, back resistance, and forward current versus voltage. Residual and unbalanced stray errors in the output signal are cancelled out by an adjustable balancing network 60 which includes four capacitors 66-69 of equal size. The transformers 24, 26, 42 may have a toroidal ferrite core with one turn of a bifilar winding on one side of the core and N turns on the opposite side of the core; this gives a low capacity between the windings.
Patent GB-295678-A (GB)
Abstract: 295,678. Burroughs Adding Machine Co., (Assignees of Pasinski, W. J.). Aug. 17, 1927, [Convention date]. Totalizing-counters; transfer mechanism.-In a machine having a plurality of totalizers movable longitudinally into and out of position for active co-operation with actuated racks and transfer mechanism, the totalizer pinions are modified to deal with non-uniform denominational values, the pinions being associated with a corresponding set of transfer tripping elements movable into operative relation with respect to the transfer mechanism. As shown in Figs. 2 and 5, applied to a machine of the Moon-Hopkins type, the totalizers 10 - - 12 are rotatably mounted on a sleeve 13 slidable on a shaft 14 and are normally urged to the left, Fig. 2, by means of a spring 17, an escapement mechanism, under the control of a manipulative key or of dogs on the typewriter carriage, being provided to adjust the totalizer carriage in position. The transfer mechanism is of known form and comprises a trip pawl 32, Fig. 5, having an off-set engaging the tail of a latch 35 on which is mounted a pin 36 adapted, at the instant of transfer, to raise an arm 37 to clear the shoulder 38 from the abutment 39. The arm 37 is pivoted to the transfer segment 40 which moves to the left when the bail 41 is lowered. In accordance with the present invention the pinions have different numbers of teeth so that it is not possible, as shown in Fig. 3, for all the teeth to be aligned. An aligning bar 43 is provided and is located at the top of the pinions to hold the pinions of those totalizers not in operative position, the bar 43 having a U-shaped offset, Fig. 2, to free the pinions of the active totalizer. To permit the use of pinions having ten, twelve, or other variation in the number of teeth, the trip pawls of the transfer mechanism are movable with the totalizers. These trip pawls of which there are two kinds, viz., 32, 44, are slidably mounted on a shaft 22 between spacing collars 46, Fig. 2, and the end plates 20, 21 of the totalizer frame. Specifications 18058/07, 18320/08, 18321/08, and 18322/08 are referred to.

Filed: 1938-10-12
Abstract: 509,735. Automatic firearms. MANCINI, N. Oct. 12, 1938, No. 29598. Convention date, Oct. 13, 1937. [Class 119] The breech-bolt of an automatic firearm is rotated into locked position by a torsional recoil spring or by a torsional spring 3 coupling the breech-bolt 1, Fig. 1, to a longitudinally guided sleeve 2. The barrel 8, Fig. 11, has longitudinal ribs 8<1> which guide ribs 2<1> on the sleeve 2, and ribs 1<1> on the breech-bolt. When the ribs 1<1> move forwardly clear of the ribs 8<1>, the torsional spring 3 rotates the breech-bolt so that the ribs 1<1> and 8<1> are in alignment, this corresponding to the locked position of the breech-bolt. The breech-bolt is fitted with a firing pin 9, Fig. 4<1>, having a tooth 9<1> guided in a slot 1<11> in the breech-bolt and passing through a. wide slot 2<11>, Fig. 5, in the sleeve 2. The tooth is held by the trigger 10 until the breech-bolt rotates into locked position, this movement carrying the tooth clear of the trigger 10 and allowing the firing pin 9 to move forward under the impulse of the spring 11 to fire the cartridge. The slot 2<11> has a bevelled end 2<111> which arrests forward movement of the firing pin so as to prevent the firing of the cartridge unless the breech-bolt has been rotated into locked position. The bevelled end 2<111> also withdraws the firing pin from the cartridge when the breech-bolt is rotated into unlocked position, this rotation being effected by a gas-operated mechanism (not shown).
