Abstract: 1291291 Capacitors BRITISH INSULATED CALLENDER'S CABLES Ltd 28 May 1971 [29 May 1970] 26040/70 Heading H1M Capacitor terminals 4 are connected to the capacitor body 1 in casing 2 by leads 7 extending through resilient seals 12 into sockets 13, corrugations 11 in the casing permitting end portion 3 supporting the terminals to move away in response to increased pressure within the casing and disconnect the sockets 13 from leads 7. The other ends of leads 7 are preferably fixed to body 1 which in turn is fixed with respect to the main part of casing 2 by insulating cap 6 and insulating disc 9 bearing against a shoulder formed by a first corrugation 10. A moulded plug 14 of polyethylene or polypropylene may have a discharge resistor 15 embedded in it. The seals between leads 7 and the casing may be frangible instead of resilient. The other end of leads 7 may alternatively be connected to another external terminal if it is not desirable to open-circuit the capacitor.

Title: Improvements in and relating to thermionic amplifiers
IPC: H01R33/22
Filed: 1933-09-23
Abstract: 425,696. Valve amplifying circuits. DICKER, S. G. S., 20, Holborn, London.- (Naamlooze Vennootschap Philips' Gloeilampenfabrieken; Emmasingel, Eindhoven, Holland) Sept. 23, 1933, Nos. 26294 and 27908. [Class 40 (v)] In a push-pull amplifier the working point on the characteristic is moved towards cut-off as the load increases so that each valve of the amplifier on weak signals amplifies both half waves of the signal but on strong signals each valve amplifies only the positive half waves. Fig. 1 shows an arrangement in which the change is effected by variation of bias produced by the anode current across resistance R. In a modification the change is effected by decrease of anode voltage due to a high impedance source, Fig. 3, (not shown). Fig. 5 shows an arrangement in which both the grid bias and anode voltage are changed. A choke S is provided in the filter for the rectified anode source and is stated to counteract in part the drop in anode voltage due to the ohmic resistance of the supply. The choke S is so designed that the core is near saturation for the average value of the direct current load. Reference has been directed by the Comptroller to Specification 408,269.

Valve gear. A single valve lever 6 opens the valve 5 before the main inlet valve. Combustion chambers. A deflector 26 which may be either cast integrally or pressed-in, shields a spark plug 4 from hot gases in the main combustion chamber 2. Cooling. The valves, nozzle holes, spark plugs and deflectors are cooled by a pump fed water distribution pipe 25. A number of holes connect the cylinder head with the cylinder block which is cooled by gravity flow. Carburation. The carburetter 7 has cylinder and pre-combustion chamber sections 10, 9, which have interconnected butterfly throttle and throttle cock valves 12, 13. The cylinder section 10 is connected through an intake manifold 19 to an inlet passage 20 and the pre-combustion chamber 9 connects through a pipe 24, a well 23 with a feed passage 21 having heat absorbing fins 22. Rich mixture enters the well 23, which is heated by conduction, and drops on to the well bottom where it evaporates whereafter it rises along the annular clearance between the well bore and pipe 24 to mix with the stream of non- condensed carburized fuel and air mixture. With conditions of high inlet vacuum such as during automobile over-run, a valve 30 is arranged to reduce the vacuum by admitting air through the pipe 33 and the orifice 29 which is uncovered by a spring-loaded valve 17 under the influence of the vacuum in the carburetter intake.

Title: Braun tube
IPC: H01J29/50
Filed: 1933-09-29
Abstract: 426,138. Cathode - ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Sept. 29, 1933, Nos. 26800 and 26801. Convention dates, Oct. 1, 1932 and Sept. 8, 1933. [Classes 39 (i) and 40 (iii)] [See also Group XXXVI] Braun tubes for use in television or as oscillographs have two or more cathode rays which are produced by a corresponding number of cathodes, are parallel to the axis of the tube between the cathodes and the deflecting devices, and are predeflected on entry into the deflecting devices so that they produce independent images on different parts of the picture-receiving screen of the tube and cannot be deflected outside these parts. The electrode systems for the separate rays have corresponding parts connected together or structurally united. Two rays may be produced by cathodes 2, 2<1>, Wehnelt cylinders 7, 71, a low-voltage anode 9 with apertures 11, 111 and preferably with concentrating cylinders 10, 10<1> and a high-voltage anode 13 with apertures 19, 19<1>. One plate 20, 201 of the first pair of deflecting plates for each ray is negatively biassed so that the rays are predeflected to scan the separate areas a, b of the screen. The other plates 22, 23 of this first pair are inclined at 20-60 to the axis of the tube. The second pair of plates 26, 27 are common to the rays and curved as shown. Current and potential curves of the same operation may thus be produced simultaneously on the areas a, b. In colour television, separate images in basic colours produced on the different parts of the screen are superimposed on a viewing screen by inclined reflectors, the deflecting systems for the different rays being connected to the same oscillation generators. Mutual repulsion of the rays when they are moving slowly before passing the anode 9 is compensated by the attraction of auxiliary electrodes such as one or more knife-edges 33 on the anode 9. Semi-cylinders 32, 32<1> screen the rays from the high-voltage leads 31. The cathodes may each have an indirectly-heated equipotential surface of hollow reflector form with the emissive area at the centre. Wehnelt cylinders may be arranged between the anodes 9, 13 and maintained slightly negative relatively to the anode 9. The predeflection of the ray avoids the " ion-cross " effect in gas-filled tubes and may be produced before entry into the plates 20, 20<1>, 22, 23. A ring-shaped auxiliary electrode at or above the potential of the anode 13 may be placed above the plates 26, 27 and part of the wall of the tube between the auxiliary electrode and the screen may be metallized and made slightly negative with respect to the auxiliary electrode. A coating on the wall of the tube at constant or earth potential prevents disturbances due to the action on one ray of wall charges produced by the other ray. The Specification as open to inspection under Sect. 91 comprises also a modification in which the rays are screened by cylindrical elements below the anode 9. This subjectmatter does not appear in the Specification as accepted.

An additional treatment with nitric acid or nitrous gases, as described in Specification 485,461, may be adopted; or the fuel after treatment with combustion gases may be mixed with fuel treated with nitric acid &c. A small amount of liquid fuel may be added to the treated extracts. Specification 603,480 also is referred to.

Abstract: 1,096,111. Fluid-pressure servomotor systems. DOWTY TECHNICAL DEVELOPMENTS Ltd. Sept.30, 1964 [July 8, 1963], No.26888/63. Heading G3P. [Also in Division F2] A manually operated fluid servomotor comprises a piston 18 movable in a cylinder 17 under the control of a valve 31. The valve 31 carries stops 32, 33 to limit its movement and controls the connection between passages 39, 41, leading to the ends of the cylinder, and an inlet 42 and an outlet 45. Restrictive passages 46, 47, 48, 49 are provided in the valve 31 to connect grooves 37, 38 to the outlet 45 on movement of the valve. The passages 46, 47 and 48, 49 are axially spaced so that they connect the grooves to the outlet in stages. A manually operated lever 28 is connected to the valve 31 by a link 35 and to the piston rod 7 of piston 18. When the lever is moved, the valve causes movement of the piston to recentre the valve. If the lever is moved past a position corresponding to full movement of the valve as determined by the stops, the piston is moved directly by the lever but the restrictive passages prevent an increase in speed of movement of the piston. The piston may act through a link 9 to adjust the angle of a swash plate pump of a transmission as described in Specification 979,445.
