Patent GB-601613-A (GB)
Title: Improvement in electrical control circuits for electronic tubes
IPC: H03K17/54
Filed: 1945-06-14
Abstract: 601,613. Switching systems for space discharge apparatus. WAYGOOD-OTIS, Ltd. June 14, 1945, No. 15143. Convention date, June 24, 1944. [Class 38 (iv)] [Also in Group XL (c)] To prevent a low impedance control circuit from influencing the operation of an electronic tube having a high resistance connected to its control electrode, as for instance in timing circuits used in lift controls, a second electronic tube which has high impedance when extinguished, but which can be rendered conducting to transmit the control currents to the first tube, isolates the control circuit from the high resistance. The first tube may be either of the thyratron or high vacuum type and the second tube is preferably a gas-filled diode, but may be a grid-controlled hard valve. The tubes and high resistance are preferably enclosed as a sealed unit which may be electrostatically and electromagnetically screened. Fig. 1 shows a tube CTB for controlling a device X, the grid of the tube being associated with a high resistance potentiometer PRA and the grid potential being variable by switches A, B for controlling the conductivity of the tube. Erratic operation may result if the leakage resistance across the switch contacts is low compared with the resistance of the potentiometer and to avoid this a gasfilled isolating tube ITA is connected between potentiometer PRA and a further potentiometer PRB of low resistance. In the timing circuit of Fig. 3, closure of button PB energizes coil CPB of a relay TR which closes contacts TRB in the work circuit and prepares a circuit over contacts TRA for the charging of a condenser CN through a high resistance RC. The charging circuit is completed at contacts TSA when the coil TS of an initiating switch is energized. At a certain condenser voltage isolating tube ITC breaks down and the controlled tube CTD conducts, thereby energizing relay coil CPA which neutralizes coil CPB and causes the relay to drop out. In a modified arrangement, contacts TSA and TRA are normally closed and are opened to initiate the timing operation, whilst in a further arrangement the relay controlling the work circuit is operated by flow of grid current in the controlled tube when the isolating tube breaks down. In the circuit of Fig. 6, condenser 2C is normally maintained charged through isolating tube 2IT at a voltage which fluctuates between the ignition and extinction voltages of the tube. The controlled tube 2CT is thus maintained non-conducting. On closure of contacts 2D3, the condenser discharges and tube 2CT eventually becomes conducting. An alternating voltage component is injected into the anode circuit of the controlled tube by a transformer TFR in order that the grid may retain control of the tube. Specification 604,455, [Group XXXVIII], is referred to.

Title: Switching apparatus
Inventor: MCCARTNEY WILLIAM ALAN
IPC: H03K5/15
Filed: 1964-04-13
Abstract: 1,105,322. Switching means. JAMES SCOTT (ELECTRONIC ENGINEERING) Ltd. May 20, 1965 [April 13, 1964], No.15153/64. Heading G4D. When a relay e.g. RL2 Fig.2 of one set of control devices is energized an associated switch RL2/B in the next control device changes state so that a capacitor C3 is charged, discharging, when the relay RL2 is cut out, to energize the next relay RL3. Thereafter the relays are energized in succession, the relay RLN changing the switch RLN/B in the first control device so that the process is repeated. In the form shown the even and odd relays are connected to different outputs of a bi-stable device so that as it changes state the relay which has been energized is cut out. A switch 53A may be positioned for either automatic scanning or manual selection. Lamps L1-LN are illuminated when the associated relay is energized. Successive control devices may be by-passed by a switch S5 which may be used to connect, for example, the input to relay RL3 to relay RL (N-1) as shown. The apparatus may be used for gating various inputs to a single output by providing each relay with a pair of contacts which make when the relay is energized.

Title: A process for preparing interpolymers; and the resulting interpolymers
Inventor: FLETCHER KENNETH LEONARD
IPC: C08F279/04
Filed: 1962-04-24
Abstract: Polymeric materials of high impact strength are made by polymerizing a mixture of a vinylidene aromatic compound and an unsaturated nitrile with a polydiene elastomer, the major proportion of the polydiene consisting of stereospecific polymer and at least 80% of the units thereof have the same structural configuration, e.g. high cis-1,4-polybutadiene and polyisoprene. Vinylidene aromatic monomers specified are styrene, vinyl toluene, alphamethyl styrene, vinyl xylene, vinyl ethylbenzene and vinyl chlorobenzene.  Polymerization may be carried out by bulk, emulsion or bulk/suspension techniques. In a preferred process the polydiene is dissolved in the vinylidene aromatic-unsaturated nitrile mixture, then a small quantity of a copolymer of the monomers is added to salt out the polydiene as a fine dispersion. The examples describe polymerizing mixtures of cis-1,4-polybutadiene, styrene and acrylonitrile in bulk, either thermally or in the presence of a peroxy or azo catalyst.

Abstract: 1418177 Valves SULZER BROS Ltd 2 April 1973 [10 April 1972] 15644/73 Heading F2V [Also in Division G3] A pilot valve controlled relief valve for the steam line of a nuclear reactor comprises a servopiston 12, the lower end 13 of which cooperates with a seat 2, sliding in a cylinder 10 and loaded by a spring 55. The chamber 30 above the piston is in permanent connection with the inlet 3 via restricting passages 31, 32. Pressure in the inlet 3, fed via line 59, operates a pilot valve 53 to connect line 41 to a low pressure region, such as the outlet side 4 of the main valve. This allows steam in the chamber 30, fed via passages 31, 32 when the valve is closed, to leak away rapidly via passages 25, an initially large clearance between the pilot piston 15 and the neck portion 23 between chambers 22 and 24, and a large diameter passage 40. The resulting fall in pressure in chamber 30 causes the piston 12 to move with considerable acceleration thus opening the valve rapidly. However, as the pilot piston 15 moves upwards it enters the neck portion 23, the diameter of which is slightly greater than that of the piston 15 and the rate of fall of pressure in chamber 30 is reduced with consequent reduction in the acceleration of the piston. Finally, the lower end of the piston 15 leaves the neck portion 21 between chambers 22 and 30 to open up a less restricted flow path between the chamber 30 and the line 41 but still sufficiently restricted to cause the piston 12 to be retarded so that when it reaches the top of its travel it is moving very slowly and pressure in the chamber 30 is so low that there is no tendency for the piston to move down again. In Fig. 2 (not shown), an electromagnetic pilot valve (63) is operated by a pressure sensitive switch (61) and a further fluid pressure operated pilot valve (83) is provided to cover the possibility of electric power failure.

[Also in Group VII] A machine for forming or shaping a shoe upper part, such as the heel end, comprises a bottom plate 36 bolted to a table T and carrying a pedestal 38, in the rounded top 40 of which is supported an operating shaft 41 (not shown) which may be coupled, by the operation of a treadle 74, through a clutch collar and dog, to a pulley 57 connected to a driving motor, to cause a crank head 93, upon which one of a pair of complementary die elements is mounted, to be reciprocated. The other die element is supported on a block 51 on the bottom plate 36 and both elements are preferably heated, The arrangement is such that on initial depression of the treadle 74, one end of an arm 100 connected to a pin 95 is moved downwards against springs 94 to cause pressure to be applied to the crank head. In one modification described, the head may be initially lowered to align and heat the work by depression of a second treadle 104, or this operation may, in a second modification described, be performed by a preliminary depression of a single treadle, a further depression of which may actuate the clutch to apply pressure to the work as indicated above. Release of the main treadle in each case relieves the pressure on the work. Specifications 720,136 and 720,137, [both in Group VII], are referred to.

[Class 134] An umbrella frame has telescopic stick and ribs, stretchers 6, Fig. 2, each of which is pivoted to a sleeve 5 which is arranged on the outer rib part 4 and is slidable on the inner rib part 3, and a spring latch 10 which prevents telescoping of the rib parts when the frame is partially opened by a spring 13 and, together with a stop 14 on the inner rib part, locks the ribs when the frame is completely opened. The latch 10 is pressed by the spring 13 to engage a stop 12 formed by a constriction in the rib part 3. The pins 9, 11 are arranged so that the latch cannot engage the stop 12 when the frame is closed ; the rib parts can therefore telescope in this position. In another form, the sleeve 5, Fig. 6, has stamped out portions to form a guide for the rib part 3, the holes 16 thus formed are used for attaching the cover to the frame. The spring 13 engages the inner side of the latch 10, which may, however, be replaced by an extension of the spring 13 adapted to engage in a recess in the rib part 3 for locking purposes.
