Title: Bistable multivibrator

Filed: 1972-09-27
Abstract: 1342465 Transistor bi-stable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Sept 1972 [30 Sept 1971] 44606/72 Heading H3T [Also in Division H1] Auxiliary transistors T5, T6, of opposite type to the rest and connected in shunt paths between collector and base of respective control transistors T3, T4 of a bi-stable pair T1, T2, have their bases connected to the trigger imput A together with the steering capacitors C1 C2, in order to improve switching reliability. The auxiliary transistor T5, say, associated with the conductive side of the bi-stable, is held off by the low collector potentials of T1, T3 and the zero level at A; and T6 is on. Thus C2 is charged and Cl is not, so that T4 base is taken more positive by the next positive trigger pulse at A than is T3 base, whereby T4 turns on and changes the bi-stable state. The connection of the auxiliary transistors' (T5, T6) bases to A ensures that T5, T6 go off when a trigger pulse occurs to avoid the disadvantage of a prior art circuit (Fig. 1, not shown), wherein continuing conduction of an auxiliary transistor T5 or T6 partly dissipates the trigger pulse, and also causes leakage of charge stored on C1 or C2 through the collector base junction of T5, T6. A second emitter e<SP>1</SP> 1 , e<SP>1</SP> 2  on T1, T2 is connected to the base of T3, T4 to improve immunity to spurious pulses on the trigger line A. Additional transistors (T5<SP>1</SP>, T6<SP>1</SP>) of the same type as T5, T6 may be connected (Eig. 3, not shown) in series with T5, T6 with their bases controlled by the collector potential of T2, T4 or T3, T1 of the opposite half of the bi-stable.  In integrated circuit form (Fig. 4, not shown) the parallel pairs of transistors T1, T3 and T2, T4 are formed in the lower left and right portions respectively of the layout, the emitter regions being formed in the base regions which are formed in turn in the collector regions, all being identified by the appropriately suffixed letters e, b, c. Transistors T5, T6 connected between collector and base of T3, T4 respectively, are formed as lateral transistors at the top of the layout. A common N-type base region (inside dash-dot line) carries the respective collector and emitter regions; and also carries an extra N + diffusion (inside dashed line) which forms a PN junction with the collector regions (D1, D2), to constitute capacitors Cl, C2 between the respective collectors and the common base.

Filed: 1968-09-24
Abstract: 1,200,530. Automatic weapon. BREVETS AERO-MECANIQUES S.A. 24 Sept., 1968 [6 Oct., 1967], No. 45352/68. Heading F3C. In an automatic firearm in which the breech is unlocked by a member actuated by a recoiling part 6 of the firearm, a primary cylinder 33 in which is disposed a primary piston 34 connected mechanically, 34b, 28, to the recoiling part, communicates with a secondary cylinder 35 in which is disposed a secondary piston 36 actuating the member 23, 22 operating the breech block 2, the cylinders being filled with liquid between the pistons, the effective cross-section of the primary piston being greater than that of the secondary piston to impose on the latter a speed greater than that of the recoiling part, a communicating passage 44 being provided between the two sides of the primary piston, the passage being capable of being blocked off at an adjustable point of the stroke of that piston to permit adjustment of the point at which the speed augmentation, and hence firing rate, occurs. The cylinder 33 is provided with two sets of helical passages 44 and 45 (Figs. 2a and 5) while the primary piston 34 has helical lands 46. The passage group 44 is initially open for a rearward movement "a" of the piston 34 and is subsequently closed for a further movement of "b" + "c", the passage group 45 then re-establishing the communication across the piston. The primary piston is rotatable by a hand lever 49 to vary the distance "a", the effective stroke "b" + "c" remaining constant. Action.-On firing, the barrel 7 and part 6 recoils, driving piston rearwards. Fluid pressure between the pistons moves the smaller piston 36 rearwards at a higher speed carrying with it the unlocking push-piece 23, its projection 22 abutting face 21a of the slidable casing 9. As the latter moves rearward skews 19 engage rollers on a pin 11 carried by breech block 2 to rotate the latter from engagement with locking lugs 5 before opening the breech. After cartridge ejection a spring and a damper device return the breech mechanism, an inclined surface 26 then actuating member 27 to disengage leaf-spring 24 and allow casing 9 to move forward relatively to the block 2 to rotate and lock the latter. The primary piston is provided with passages 54 co-operating with a disc 55 to act as a oneway valve allowing fluid to return to the righthand side of the piston when the weapon recuperates.

Abstract: 1411423 Facsimile reproduction P ZIMMER 4 Oct 1972 [7 Oct 1971] 45645/72 Heading H4F In a process for producing a printing block or member, wherein the scanning of an original at 16 controls the flashing on and off of a light source 9 continuously scanning a photosensitive element 1, to produce a reproduction of the original with a superimposed half tone screen effect, the element 1 comprises a highly photosensitive layer, e.g. of silver halide-gelatine or chrome-gelatine, overlying a relatively insensitive photosensitive layer, e.g. of positive or negative printing lacquer, on a support matrix. Following exposure of the upper layer only, by source 9, that layer is developed and the element exposed to an intense uniform exposure to transfer the pattern to the lower layer. Such exposure may be by uniform illumination, or by scanning over the entire element with a light source. Development of the lower layer may be followed by an etching step or an electrolytic deposition step (metallic matrix) to produce the final block. As particularly described, linearly moving photodetectors 17, 17<1> alternately scan the entire original, which is mounted on a rotating cylinder 16, so that linearly moving source 9 produces a series of reproductions along the length of a rotating cylindrical element 1. A unit 22 produces an odd number of pulses for every two rotations of element 1, such pulses, being gated by a unit 21 controlled by the output of photodetector 17 or 17<1>, and used to activate the light source. A hexagonal screen effect is thereby obtained. The pulses may alternatively be obtained from the drive motor 4, if of the stepping type. Reference is also made to projecting successive recording points at random intervals, to prevent moirÚ patterns, and to the production of flat printing stencils.
