A subset incorporating a hybrid transformer is matched to line by means of a capacitive network such that the reactance of the set plus network is a minimum at the high frequency end of the speech band. The normal characteristics of a subset and a line are depicted in Fig. 1 where curves 1, I<SP>1</SP> and 2, 2<SP>1</SP> indicate the characteristics with respect to frequency of the resistive and reactive components of lines using 26 and 22 gauge conductors respectively and Ra, jxa indicate the similar characteristics for a set. A mathematical discussion shows that by capacitively loading the essentially inductive set a good match with an essentially capacitive line can be obtained in respect of both resistive and reactive components. Fig. 2 shows the improved characteristics obtained by using a parallel RC network across the line and the remaining Figures (not shown) indicate the similar improvements obtained by using: a single shunt capacitor; a series RC network in shunt with the line; a parallel RC network in series with a capacitor across the line; a capacitor in shunt with transformer winding I or transformer windings I and III (Figs. 6, 7, not shown); a capacitor or a resistor in shunt with the line and another capacitor in shunt with winding I; and a series RC network across the line with a capacitor in shunt with winding I (Fig. 10, not shown).

Abstract: 1,238,059. Active filters. POST OFFICE. 15 Dec., 1969 [18 Dec., 1968], No. 60203/68. Heading H3U. An impedance converter comprises an amplifier 21 with resistive feedback paths 23, 24 to inverting and non-inverting inputs, and an output resistor 25, whereby the impedance at the input 20 has a resistive component together with an impedance inversely proportional to that of a load impedance 26 connected across the output resistor 25. The resistors are chosen such that R 22  = R 25 , R 23  = R 24 . In order to simulate a "floating" impedance, the resistor 25 may be replaced by a second similarly connected converter, Figs. 8, 9 (not shown). With this cascade arrangement, the feedback to the inputs of the first amplifier may be derived from the output of the second amplifier, Fig. 25 (not shown). Filter circuits using such converters to simulate series and shunt inductors are described. In order to obtain a gyrator, i.e. no resistive component to the simulated impedance, three converters may be connected incascade, Figs. 18, 19 (not shown).

Abstract: 1,251,898. Rotary conveyers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 Feb., 1969 [7 Feb., 1968], No. 5832/69. Heading B8A. Articles Fig. 1 on a feeding device 7 pivoted at its mid point, are fed to turntable 25 by pivoting the device at its mid point and the articles on the turntable are then conveyed in succession from receiving station 8 to a hardening station 10, and they are then discharged at 11. Feeding device 7 Figs. 2a.-The device 7 includes a rod 13 and a guide member 18 secured to a shaft 15 at their mid point, the shaft being held by a disc 17 co-operating with a locking lever 16 and being periodically driven through 180 when released by the lever 16. The articles 12 are fed by hand on to rod 13, the other part of each article engaging the guide member 18 and the article sliding down the rod 13 past a pivoted arrestor 19 and a bell crank lever 22. When the rod is filled, the device 7 is rotated 180 degrees around its shaft 15 so that articles are now ready to be fed on to respective studs 23 carried pivotally by mountings 29 secured on the turntable 25. The discharge arc of each article from the rod 13 is controlled by the arrestor 19 bellcrank lever 22 and a pusher 24 slidingly carried in a pivoted mounting 32 and operated by a cylinder 27.  Operation.-Turntable 25 rotates to bring mounting 29 into position beneath the rod 13, at which position the turntable is displaced upwards to the position shown. The bellcrank lever 22 is displaced clockwise by cylinder 21 to cause the lowermost article to pass the arrestor 19. The article is then displaced on to the studs 23 by the pusher 24 operated by the cylinder 27. When the next mounting 29 moves into the position shown, the next article is discharged from the rod 13. In this way, when all the articles are discharged from the rod 13 the rod and guide member are together rotated through 180 degrees into the receiving position whilst the other part of the rod 13 and guide member 18 is simultaneously brought into the discharge position.

Abstract: 1,251,927. Dynamo-electric machines. SIEMENS A.G. 22 May, 1970 [24 May, 1969], No. 25020/70. Heading H2A. [Also in Division G1] Means for generating a unidirectional voltage related to a speed of rotation comprises a polyphase generator arranged to provide phase voltages having a flat-topped waveform configuration, and means for sequentially switching the flat topped portions of each waveform in turn to a common output. As shown a four-phase generator includes phase windings A, B, C, D and a permanent magnet rotor 2. Mounted on the rotor is a metal strip 3 extending over 180 degrees which serves as an exciting means for two inductive transmitters 4, 5 mounted at 45 degrees on either side of the field axis of the winding A. The transmitters consist of inductive proximity switches in oscillator circuits which become unbalanced and emit a signal when the metal strip is adjacent thereto. Signals x, y (which may be regarded as binary " 1 " signals) from the transmitters 4 and 5 are applied to inverting gates 9, 10. The outputs from these gates x, y will be "0" when the signals x, y are binary " 1 " and will be binary " 1 " when x and y are zero. Consider a clockwise rotation of the rotor. For  revolution the strip 3 will be adjacent transmitter 4 only (signal x); for the next  revolution it will be adjacent 4 and 5 (signal x and signal y); for the next  revolution it will be adjacent 5 only (signal y) and for the last quarter it will be adjacent neither (no signals). The outputs of the inverter gates 9, 10 in corresponding periods are #y, zero, #x, and #x+#y. Four AND gates 11, 12, 13, 14, are arranged to respond to the combinations x+y, x+y, x+y y and x+y respectively and actuate electronic switches 19, 20, 21, 22 to connect phase windings A, B, C, D to a common terminal (23 or 25) for successive quarter cycles. The generator design involves a flux of triangular waveform which provides a phase voltage waveform having a flat portion extending over more than 90 degrees, so that the switching arrangement results in a unidirectional voltage whose amplitude is related to the speed of rotation. A modified switching arrangement is envisaged for a generator where the windings are connected in series opposition (Fig. 3, not shown). A further modification (Fig. 4, not shown) discloses an arrangement of a plurality of conductive strips and transmitters for use with a 16 phase generator.

Abstract: 1,258,801. Data processor. HONEYWELL Inc. 23 Jan., 1969 [3 April, 1968], No. 3973/69. Heading G4A. Synchronizing device in a data processor comprises a first addressable sequencer providing microinstructions for an address generator, a second addressable sequencer providing microinstructions for an arithmetic and logic unit, the microinstruction word addresses being sequentially advanced and means to inhibit the advance of one of the sequencers when a microinstruction word containing an interlock character is obtained and enabling means coupled to the other sequencer to enable the advance of the inhibited sequencer when a microinstruction word containing an interlock character is obtained from the other sequencer. Instructions from Main Memory cause Address Generator 61 to generate an Address and cause the arithmetic unit 62 to accept the A operand produced by the address. A sequence Controller 39 provides a starting address to a Read Only Memory Address Register 32, the address being incremented by INCR 52. Address Generator 33 and local Register 38 under the control of clock 51 access the control signals from an Address Generator Micro- Operation Generator 36. These are applied to Address Generator Element 50 to supply main memory addresses to Register 55. Generator 36 can also generate Branching Micro-Ops fed to an AG Address and Branch logic 53. If a branching instruction depends on the result of an arithmetic operation a signal on an External Conditions line can be supplied to Generator 36. An Operation Code Register provides a starting address for Read Only Memory Address Register 42 feeding arithmetic unit ROM 43 supplying local register with control signals for the Operation Generator 46. Arithmetic and logic Element supplies results of arithmetic operations to the main memory and receives operands on line 63 from the main memory. For the cases when one of the units must wait for a result of an operation occurring in the other unit interlock circuits 40, 41 are provided. Certain selected micro-operation words contain interlock characters in fields 38, 40 of the words in registers 35, 45 which may be single control bits, a "1" indicating an interlock and a "0" indicating no interlock. In the event of an interlock signal from Register 35 with no signal from Register 45 Gate 40 produces a signal preventing operation of clock 51 and prevents accessing of further words from the ROM 33. When an interlock signal appears in Register 45 the clock is freed and accessing continues. If an interlock occurs in the Arithmetic Unit the word containing the interlock includes a repeat address so that the same word is continually accessed. The interlock signal supplied to Gate 41 has no effect until an interlock signal appears in Register 35 when the gate is enabled and supplies a signal to Address Register 42 incrementing the address. Identical interlock gates can be provided.
