IPC: H01F30/08
Filed: 1920-12-15
Abstract: 176,539. British Thomson Houston Co., Ltd., (General Electric Co.). Dec. 15, 1920. Protective arrangements.-In a combined resister and reactor for use as a protective device in systems of electrical distribution, the resister is formed as a separate unit distinct from the reactor and comprises resistance elements of carborundum or other material having a desired electrical characteristic, for instance decreasing resistance with increasing applied power or voltage, connected in shunt with sections of the reactor. The resistance elements may be embedded in a plastic insulating block supported adjacent to the reactor, taps from the elements connecting with'taps from sections of the reactor. In the form shown, the resister comprises carborundum rods 30 embedded in an insulating block 21 and provided with projecting taps 23, 24, while the reactor comprises a conducting coil 13 provided with projecting taps 25 and embedded at intervals in circumferentiallv spaced plastic insulating supports 12 supported on a base 10. The 'block 21 may thus be supported at the centre of the coil 13 with the taps 23, 24 connecting with the taps 25. Specifications 4133/14, 4931/14, and 109,129 are referred to.

The first catalyst may be Pd. Both catalysts are preferably supported, e.g. on Al 2 O 3 . In the Figure the coolant system of reactor 10 comprises a heat exchanger 12, blower 14 and purification loop 16. The gas in the purification loop passes through the two catalysts, in this example contained in a single reactor 17, and is cooled in heat exchanger 20, then the water formed in the oxidation is removed at 22.

Title: Improvements in or relating to the control of iris diaphragms for opitcal objectives
Inventor: CHAPMAN ALAN
IPC: G03B9/08
Filed: 1958-11-06
Abstract: 930,322. Optical apparatus; diaphragm control mechanism. RANK PRECISION INDUSTRIES Ltd., [trading as TAYLOR, TAYLOR & HOBSON]. Aug. 7, 1959 [Nov. 6, 1958], No. 35673/58. Class 97 (1). [Also in Group XXIV] The movement of an iris diaphragm for an optical objective is controlled by connecting its driving ring with the driven member of a set of three coaxial sleeve members, one of which is fixed and forms part of, or is carried by, the objective mount, while the third is a control member, the rotation of which causes a radially. extending pin engaging suitably shaped slots in the three sleeves to traverse a fixed path defined by the slot in the fixed sleeve thereby causing it to bear against the slot sides of the driven member, which is thus caused to rotate at a rate, relative to the rate of rotation of the control member, governed by the shape of the slots. Axial movement of at least one of the two rotatable members is constrained either entirely by abutment means or allowing slight, controlled motion by screw-thread engagement with an adjacent member. Conveniently, the control sleeve E has an axial slot E<SP>1</SP>, and carries a slidable bearing J which holds the pin H in correct radial orientation with respect to the axis G, and the fixed sleeve A<SP>1</SP> is disposed between the control sleeve E and the driven sleeve B<SP>1</SP>. A mechanism comprising three such sleeves may be adapted for fitting over an existing objective mount whose diaphragm control is then connected to the driven sleeve. A number of different objectives mounted on a turret can be simultaneously adjusted for their appropriate diaphragm setting by means of a single rotatable member engaging the control sleeves of the diaphragm control mechanisms separately associated with each objective. In order that there be no further rotation of the driven member of the diaphragm control mechanism associated with a particular objective which is at full aperture whilst the common control wheel engaging its control sleeve may yet be usefully rotated for other objectives, the cam slots of the driven and fixed sleeves have superposable end portions such as A<SP>6</SP> and B<SP>3</SP> in Fig. 4 in which the moving pin causes no rotation.

[Class 87 (ii).] A machine for compressing powder into a coherent mass, and described particularly with reference to filling containers with face powder to form compacts, comprises a table 4 apertured to receive a plunger 6, and provided with a pivot 3 about which swings a plate 2 having a bottomless hopper 1 for the loose powder and a resiliently mounted abutment 32. The plunger 6 is cam-actuated, with provision at 28 for adjusting its stroke and with an adjustable stop 13 for limiting its descent, in order to vary the capacity of the mould cavity. The plate 2 is first swung by a hand-lever 29 to place the hopper in register with the cavity above the plunger 6 in order to fill this cavity with powder and is then swung clear after which an inverted container 5 is placed over the cavity, the plate 2 then being moved to align the resilient abutment 32 with the container. The plunger is then actuated to compress the powder and after retraction, the plate 2 is swung clear and the plunger again actuated to eject the container filled with the compressed powder. The machine may be actuated by hand or power.

Abstract: 1393009 Synchronizing data transfer BUR. ROUGHS CORP 2 Aug 1972 [30 Aug 1971] 36083/72 Heading G4A The transfer of data in binary coded decimal form in an electronic calculator using shift registers R1, R2, R3 (Fig. 1), driven by clock pulses, is synchronized by utilizing an auxiliary 4 bit register R4 connected between the output and the input of one of the registers e.g. R1 and set to a special code character, unused in binary coded decimal, e.g. 1111. To transfer data out from any of the stores R2, R3 initially four clock pulses are fed to the stores R1, R4 so that the least significant decimal digit in register R1 is entered into register R4 and the contents of register R4 are entered into the least significant digit position of register R1. Registers from which data is to be transferred are then clocked in synchronism with the registers R1 and R4, a check being made by a decoder after every four clock pulses to determine whether the special code character has been re-entered into the auxiliary register. When the decoder recognizes the character transfer of data is stopped. The auxiliary register may be connected by switches between the input and output of any one of the registers.

Title: Improvements in or relating to electric communication systems
Inventor: LEY DOUGLAS AUBREY
IPC: H04B3/44
Filed: 1956-11-27
Abstract: 836,037. Automatic volume control. GENERAL ELECTRIC CO. Ltd. Nov. 22, 1957 [Nov. 27, 1956], No. 36287/56. Class 40 (4). [Also in Group XL (c)] A terminal station of a communication system has a receiver the gain of which is controlled by the amplitude of a received signal, discontinuation of the received signal disconnecting power from equipment at the terminal other than that required for listening out and also disconnecting the automatic gain control of the amplifier and substituting a fixed gain. The arrangement avoids spurious operation due to amplification of noise since with no received control signal the fixed gain of the receiver is below maximum. The system envisaged utilizes both-way multichannel carrier working over open-wire lines. Transmission is effected over a converter 4, in which a relay S may be used to interrupt the carrier frequency of a particular channel, a compressor 6, a modulator 7 with channel oscillator 8, amplifier 9, a filter, and a coupling and matching unit 12 to line 11. Reception is made over a filter, amplifier 18, demodulator 19, amplifier 16, and expander 15. Demodulator 19 also provides an input for a receiver 20 which recognises the presence of a carrier signal incoming on the line 11 and controls relays A and R. Relay R repeats interruptions in carrier frequency used for code signalling. Relay A connects power to compressor 6, oscillator 8, amplifier 9, expander 15 and amplifier 16, and connects up the thermistor 21 in the automatic gain control of amplifier 18, in response to the received carrier signal. Power is also connected to the above-mentioned circuits when relay S is operated for transmission. The amplifier 18 may comprise the three-stage transistor amplifier as shown, in which feed-back from winding 51 of the output transformer 36 in the push-pull stage 33, 34, is rectified and applied to resistor 48. A decrease in output will lower the potential across resistor 48 and increase the numerical value of the bias to the base of transistor amplifier 39, thereby increasing its gain. A thermistor 21 acts in opposition to the voltage feed-back and limits the variations in gain control. Contacts A2 disconnect the feed-back loop and connect up a fixed bias of intermediate value in the absence of a received carrier signal.
