Title: Bistable circuit with negative resistance diode
IPC: H03K3/315
Filed: 1960-12-21
Abstract: 964,898. Cascade counters. RADIO CORPORATION OF AMERICA. Dec. 21,1960 [Jan. 13, 1960], No. 43969/60. Heading G4A. [Also in Division H3] A bi-stable circuit comprises a negative resistance diode coupled to a transitor so as to control its emitter-collector emission. A tunnel diode 12, Fig. 3, is connected in parallel with the baseemitter circuit of a PNP transistor 44,and is connected to bias potentials +V B  and -V A  such that when the tunnel diode is in one stable state the transistor is cut off,and when it is in the other stable state the transistor is heavily conducting. Triggering pulses for switching the diode from one state to the other may be applied from sources 71, 73. Switching may be effected by applying pulses of like polarity from sources 71,73 alternately, or alternatively either source may supply pulses of opposite polarity alternately. The circuit may be modified for a NPN transistor by reversing the polarity of the diode, Fig. 4, (not shown). In a further modification, Fig. 5, a steering circuit is provided to direct triggering pulses alternately to the anode and cathode of the diode. When transistor 44 is cut-off the potential at its collector is -V c , and this negative potential is used to reverse bias a diode 92 so that triggering pulses are prevented from being fed to the anode of tunnel diode 12. In the "on" state of the transistor, both diodes 92, 98 are conductive but the values of the capacitors 94,102 are arranged such that the time constant of capacitor 94 and resistor 62 is greater than that of capacitor 102 and resistor 62 and the signal fed through capacitor 94 is therefore effective for a longer time. Alternatively the two capacitors may have the same value and a further capacitor may be connected across resistor 58, Fig. 6 (not shown). A number of stages may be cascade to form a binary counter Fig. 7, (not shown). Specification 964,897 is referred to.

Title: Magnetic core logic device
IPC: H03K19/166
Filed: 1963-11-12
Abstract: 981,855. Magnetic storage devices. AMP Inc. Nov. 12, 1963 [Nov. 23, 1962], No. 44561/63. Heading H1T. [Also in Division H3] An EXCLUSIVE OR device comprises a rectangular loop core 10 (Fig. 2), having input windings X<SP>1</SP> and Y<SP>1</SP> energizable to switch the remanent flux in different paths, an output aperture 4<SP>1</SP> through which passes an output winding Z<SP>1</SP>, a priming winding 6<SP>1</SP> passing through aperture 4<SP>1</SP> and capable of switching flux about that aperture after flux switching has been produced by one, but not both, of the input windings and a clearing winding 5<SP>1</SP> (which may be separate from the priming winding 6<SP>1</SP>) which when energized reverses the direction of the flux in one of the limbs of the output aperture 4<SP>1</SP> so inducing a substantial output. The core begins in the cleared state with all the remanent flux clockwise (Fig. 3, not shown). A single input in either X or Y then produces flux in opposite directions on both sides of output aperture 4<SP>1</SP> (top arrangement in Fig. 3A or 3B, not shown), due to the action of the Figure eight winding 8<SP>1</SP>, 91. A smaller rectangular priming pulse then switches flux at aperture 4<SP>1</SP> so that it is all anticlockwise in relation to that aperture (see lower part of Fig. 3A, not shown). A clearing pulse in winding 5<SP>1</SP> then reverses the direction of the flux in the outside leg at aperture 41 and a large output is produced. Simultaneous pulses in X and Y produce fluxes in the same direction on both sides of 4<SP>1</SP> and reversal of this on clearing produces equal and opposite voltages in loops 8<SP>1</SP> and 9<SP>1</SP> and hence no output. If the load is not of high impedance a rectifier may be connected in the output circuit or a second core 11 may be employed. An output as shown in Z<SP>1</SP> then reverses the clockwise flux around the major aperture 2<SP>1</SP> of core 11 inside apertures 31 and 4<SP>1</SP>, the flux round 4<SP>1</SP> is then reversed slowly by a small current in 13 and a clearing current IA in 12 then switches the flux in the outer leg of aperture 4<SP>1</SP> thus producing an output in 14 which may be connected to a further storage core. Cores 10 and 11 may be replaced by a single core with suitable flux paths.

Abstract: 1,211,860. Extruding composite pipes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 24 Sept., 1968 [3 Oct., 1967], No. 45026/67. Heading B5A. [Also in Division F2] A continuous process for the production of a laminar pipe having a foamed core and inner and outer surface layers comprises co-axially extruding two pipes of thermoplastic material and extruding a foaming synthetic resin into the cavity between the said two pipes. The laminar pipe may be prepared by dividing a stream of molten thermoplastic material into two annular concentric paths, cooling the material in these paths and extruding a foaming material between the formed pipes which emerge from the extruder, the resulting pipe assembly being drawn through a forming die by moving surfaces which grip the exterior surface of the pipe whilst the foaming material foams and sets. The foamed core acts to strengthen the pipe and acts as a heat insulant. Each pipe layer may be of the same material, the inner and outer layers of the same material and the foam core of a different material, or each of a different material. Suitable materials may be polymers of α-olefines such as polyethylene, polypropylene, polybutene and poly-4-methyl pentene-1 and copolymers of two or more α- olefines such as ethylene, propylene, butene and 4-methypentene-1; polymers and copolymers of vinyl chloride optionally containing a plasticizer; polymers and co-polymers of styrene, polymers and copolymers of methyl methacrylate and acrylonitrile, butadiene, styrene copolymers. The thermoplastic material, especially that of the outer layer, may include a suitable filler such as asbestos fibres, glass fibres, glass plates or mica plates. The blowing agents for the foaming material may comprise liquid agents such as pentane and the halo- and polyhalo-hydrocarbons, e.g. methyl chloride, which may be incorporated by soaking the thermoplastic material in the liquid agent. Alternatively the blowing agent may be injected into the barrel of the extruder. The blowing agent may be a powdered, solid agent dry-blended with the thermoplastic. Suitable solid agents are the nitrogen gas liberating agents, such as azo and hydrazo compounds, and the carbon dioxide gas liberating agents, such as carbonates or bicarbonates.
