Abstract: 1,156,320. Reciprocating pumps. SKYHI Ltd. Jan. 6, 1967 [Dec. 1, 1965], No.50960/65. Heading F1A. A bucket pump can deliver relatively large and relatively small volumes of liquid to an outlet 36 on alternate piston strokes from a chamber 30 between the piston head and the inlet valve 32 and an annular chamber 18 between the piston 12 and the cylinder 10, repsectively.

Title: Method for time-divided (time multiplex) transmission of information, and equipment for the execution thereof
Inventor: ACS ERNO
IPC: H04Q11/04
Filed: 1965-12-01
Abstract: 1,134,229. Automatic exchange systems. TAVKOZLESI KUTATO INTEZET. 1 Dec., 1965, No. 51080/65. Addition to 1,069,094. Heading H4K. In a telecommunication system, signals on a number of input lines are amplitude sampled and representations of these samples, each accompanied by a representation of its destination, are time-division multiplexed on to an output channel and transmitted at the maximum traffic rate. The arrangement is generally similar to that of the parent Specification but is located at a concentrator. Each concentrator is connected to 240 lines and can make 24 simultaneous connections. The lines are sampled and the outputs are converted to P.C.M. and together with coded identities of the destination lines are multiplexed as in the parent Specification. Since each connection is actually in use for about 1/4 of the time, the multiplex signals are entered into a queueing register and read out at 1/4 speed to eliminate pauses in transmission. The output is fed to additional circuitry (Fig. 2, not shown), which divides the coded identities (Pk) out and splits them into a concentrator code (Sc) and a line code (Pf) for the wanted line. The two separate codes are inserted in place of the coded identity. The resulting signals are entered into a queueing register. The central exchange scans the queueing registers associated with 100 such concentrators at the maximum possible traffic rate, reading out one sampling code and its associated data, from each register. The codes are repeated to all concentrators but only the concentrator associated with the destination responds. This concentrator converts the sample back to amplitude form and applies it to the line specified in the line code.

Abstract: 1,171,644. Transistor radio receiving circuits. RADIO CORPORATION OF AMERICA. 15 Nov., 1966 [29 Nov., 1965], No. 51238/66. Heading H3T. A circuit responsive to modulated carrier waves comprises a direct coupled amplifier 108, directly coupled to a detector 112, the effect of changes in powersupply voltage being minimized by feeding a compensating voltage to the detector 112. An amplitude modulation radio receiver is described in which the dotted line 100 encloses a monolithic semi-conductor integrated circuit chip size 50 mils square. Transistor oscillator/mixer circuits.-The signals are picked up by a ferrite rod 118 and are coupled to the base of transistor 102 having a tunable local oscillator circuit 122. Directly-coupled IF amplifiers.-IF signals are passed via transformer 136 to a directly coupled IF amplifier 104, 106, 108 having stabilizing DC feedback via resistors 208, 210. Transistor demodulator circuits.-The output of the last IF stage 108 is directly coupled to a Darlington pair demodulator 112 comprising transistors 158, 160. A stabilizing circuit 110 provides a voltage at the emitter of transistor 194 equal to one half of the supply line voltage at terminal 204 and a further voltage at the emitter of transistor 192 equal to one half of the supply line voltage less the normal baseemitter voltage of a transistor. This voltage is coupled via emitter follower 176 and resistor 218 to the output of the demodulator 112 so as to compensate for the effect of changes in supply line voltage 204. Alternatively, the circuit may be stabilized via conductor 226. Automatic gain control circuits.-When the demodulated signal at the emitter of transistor 160 exceeds a predetermined value, transistor 180 becomes conductive, feeding a negativegoing gain control voltage via transformer 136 to the base of transistor 140, increasing the current in transistor 142 and reducing its gain. A further transistor 188 is provided so as to maintain the collector voltage of transistor 142 independent of gain control voltage.

Abstract: 1372592 Making semi-conductor connectors HONEYWELL INFORMATION SYSTEMS ITALIA SpA 5 Nov 1971 [5 Nov 1970] 51630/71 Heading B3A [Also in Division H1] Beam leads for electronic components are made by affixing one face of a metallic foil to one face of a film of photosensitive material, selectively removing portions of the metallic foil to form a set of beam leads on the photosensitive film and selectively exposing and chemically treating the other face of the photosensitive film to produce an aperture over which one end of each beam lead projects. A continuous process embodying the invention starts with aluminium foil 51 on a drum 53, Fig. 7, and a laminate 52 of polyethylene, Riston (Registered Trade Mark) solid photoresist and polyester on a drum 54. The polyethylene layer 55 is stripped from the laminate by roller 56 and the remaining layers are heated at 57 to permit pressure rollers 58, 59 to laminate the aluminium foil to the Riston layer. The aluminium surface is then smeared with photoresist 62 and the strips are passed with an intermittant motion through an exposure station 63 where masks 64 and 65 respectively define the beam leads and the aperture. The photoresist is developed at 68 and the aluminium etched at 69. After stripping of the exposed photoresist at 70, the polyester layer is removed and the Riston developed at 72 to form the aperture 82, Fig. 8, over which the beam leads project. A semi-conductor chip or other circuit is located in the aperture 82 and the contacts thereof are ultrasonically welded to the beam leads. The chips, after being tested at 74 and after duds have been punched out at 75, pass to packing or storage.
