Abstract: 583,041. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and KNIGHT, H. DE B. Nov. 10, 1943, Nos. 18654/43 and 445/44. [Class 39 (i)] The envelope consists of a ceramic cup 2, Fig. 4, sealed by a header 1 preferably also ceramic but optionally of metal. The electrode 4 is provided with a flange 9 engaging a shoulder on the rim of the cup 2 or on the header 1, so that the operation of sealing on the header at the same time positions the electrode 4 relatively to the envelope. In the spark gap shown the other electrode 10 is held against an internal shoulder 11 by lead 12, but a similar header and shoulder construction may be used to position this electrode also. The same arrangement may be applied to a diode, with directly or indirectly heated cathode. In a triode, the grid may be so positioned, the cathode leads being sealed through the header by conventional beads, but Fig. 7 shows an arrangement in which both grid and cathode are positioned by the same sealing operation. Grid 15 has a flanged extension pressed against shoulder 9 by a cylindrical spacer 21, while cathode 17 has leads 22 spread out between spacer 21 and the header 1. Leads 23 are taken out through channels in the ceramic bodies 1, 21. A continuous shoulder may be replaced by a series of discrete projections.

Patent GB-726489-A (GB)
Title: Improved method of heating reaction apparatus for carrying out exothermic gas reactions
IPC: B01J12/00
Filed: 1953-07-08
Abstract: A continuous catalytic process for the production of formaldehyde by oxidation of methanol or methane with air is initiated in a non-inflammable mixture of the reactant gases in which one gas is present in stoichiometric excess of the second gas, by passing the main stream of gas mixture through the cold reaction apparatus and introducing and igniting regulated quantities of the second gas through a separate gas inlet into the main gas stream in front of the actual reaction zone; the two gas streams react with the formation of flame, thus heating the reaction apparatus.  In an example, a mixture of air and excess methanol vapour is passed through a catalytic reaction zone and air is introduced and ignited at a number of points in front of the reaction zone, flames being formed which do not reach to the catalyst.  When the reaction temperature is attained the stream of air is shut off and the reaction continues automatically. Alternatively the main feed gas may contain excess air, in which case methanol vapour is introduced as the secondary stream.ALSO:A continuous exothermic catalyst reaction is initiated in a non-inflammable mixture of at least two gases in which a first gas is present in stoichiometric excess of a second gas, by passing the main stream of gas mixture through the cold reaction apparatus and introducing and igniting regulated quantities of the second gas through a separate gas inlet into the main gas stream in front of the actual reaction zone; the two gas streams react with the formation of flame, thus heating the reaction apparatus.  Ignition may be effected by a spark gap or an incandescent wire.  The secondary gas stream may be introduced perpendicular to the main stream in a tangential or radial direction.  In modifications (1) the second gas is fed gradually into the main gas stream which contains initially only the first gas, and simultaneously the secondary gas stream is gradually reduced.  (2) the main gas stream contains only the first gas, and when the required temperature is reached, the secondary gas stream is stopped to extinguish the flame, and then restarted.  In an example, formaldehyde is formed from a mixture of methanol vapour and air (see Group IX (b)).  The process is also applicable in the oxidation of ammonia to nitric acid and the production of hydrocyanic acid from methane and ammonia in the presence of air or oxygen.

Title: Improvements in and relating to temperature or pressure responsive electric switches
IPC: H01H37/36
Filed: 1952-07-29
Abstract: 738,497. Thermal switches; fluid actuation of switches. GENERAL ELECTRIC CO. July 29, 1952 [July 30, 1951], No. 19152/52. Class 38 (5). A switch comprises a pivoted operating lever movable between two positions, a flexible contact-carrying member operable by the lever which is acted on by two springs, one being stronger than the other and urging the lever to one position, and pressure or temperature responsive means for counter-acting the stronger spring so that the lever is moved to the other position to operate the switch. In one form applied to refrigerator control, the operating lever 41 is pivoted at 42, 44 and is biased clockwise by a spring 31 connected to the lever by a rod 25 resting on the top of a bellows 22. The lower end of spring 31 engages a cup 26 resting on shoulders on rod 25 and the upper end engages a part 29 of a bracket 27 having a screw 34 engaging an adjusting cam 35. The right-hand end of lever 41 has a knifeedge 66 engaging a U-spring 65 the other limb of which engages a spring arm 68 which is adjustable by a screw 70 to alter the switch differential. The lever 41 also has an extension 48 engaging between the arms of a spring 59 (Fig. 6), the upper arm of which carries a movable contact 58 co-operating with fixed contact 53. Spring 65 always biases the lever 41 counter-clockwise since it does not go overcentre but it is overpowered normally by spring 31 which holds the lever in the position shown in Fig. 1 with a stop 49 on part 48 engaging a fixed stop 50. When the temperature increases the bellows expands and forces rod 25 upwards, allowing spring 65 to move lever 41 counter-clockwise, the contacts 53, 58 being closed rapidly by a hammer blow from part 48. On decrease of temperature, the spring 31 overpowers springs 65 and the contacts re-open. The cam 35 has an extension 38 which can be moved to engage a part 73 of lever 41 to hold the contacts open irrespective of the state of the bellows. Defrosting is allowed in one position of cam 35 in which spring 31 is compressed to its greatest extent.

Filed: 1967-04-26
Abstract: 1,146,817. Brake failure alarms. MIDLANDROSS CORP. 26 April, 1967 [19 May, 1966], No. 19181/67. Heading F2E. [Also in Division H1] A device for giving a warning indication of failure in either of two mutually isolated fluidpressure systems, such as front and rear braking systems of a motor vehicle, comprises two change-over switches connected in parallel and respectively operated by increase in pressure in the two systems. Contact discs 45 and 46 secured to flexible diaphragms (see Division H1), respectively coupled to the two fluid pressure systems, are spring-urged to the positions shown. Upon application of the brakes the contact discs normally move to interconnect fixed contacts 53, 54 and 55, 56, respectively, thereby energizing the usual warning lights 60. However, should one system fail the contact disc associated therewith remains in the position shown when the brakes are applied and movement of the other contact disc not only energizes the normal warning lights 60 but also energizes the circuit 61a to a brake failure indicator light 61 on the driver's console. In a modification (not illustrated) the contact discs 45 and 46 are maintained midway between their associated fixed contacts by residual pressures in the systems, and failure of residual pressure results in actuation of an alarm light.

Filed: 1949-07-22
Abstract: 668,570. Rotary pumps. MONO PUMPS, Ltd., and ALCOCK, E. Oct. 23, 1950. [July 22, 1949] No. 19361/49. Class 110(ii). Regulating means 9 for a pump having a helical rotor cooperating with a stator of helical form, such as described in Specifications 400,508 and 633,583, [Group XXII], comprises a byepass 8, 8<SP>1</SP> from the pump lines including a valve which closes, or partly closes, the byepass when the fluid flow in it exceeds a pre-determined figure. Fig. 2 shows one means. When the flow, from the pump delivery, which enters a chamber 12 from a pipe 8, exceeds a pre-determined figure, a ball valve 13 is lifted to close the chamber outlet 14, this, preferably, being chamfered. One or more grooves may be cut across the chamfered seat to allow a small flow around the byepass circuit at high pump discharge pressures. When the pump discharge pressure falls, the ball drops through gravity, or may be forced downwards by a rod 18 controlled by a piston in a chamber 15. The piston is lifted, against light spring pressure, by the partial vacuum in a pipe 11 which is connected to the suction side of the pump. The above arrangement ensures a large flow through the byepass 8, 8<SP>1</SP> when the pump discharge pressure is low. In an alternative arrangement the means to close the outlet 14 comprises an aerofoil-shaped flap, pivotally mounted near its trailing edge. When the velocity of the in-coming liquid exceeds a certain figure, the flap is raised and closes the port 14. A further arrangement includes a venturi in the byepass circuit, pressure variation due to changes in velocity in the venturi being applied to a piston-cylinder assembly, the piston acting on the valve in the byepass.

Title: Improvement in or relating to remote controlled electrical reversing switches
IPC: H01H50/32
Filed: 1935-07-08
Abstract: 463,722. Electromagnetic switches. ELLIS, L. S. E. (Schorch-Werke Akt.-Ges.) July 8, 1935, No. 19471. [Class 38 (v)] A remote-control arrangement for a reversing switch in which the switch is moved into predetermined positions by operation of a corresponding control switch to energize a magnet coil has, for those movements of the reversing switch which are opposed by an energized magnet coil, in addition to " holding " contacts which complete a maintaining circuit, so-called " locking " contacts which are opened when another control switch is operated to energize another magnet coil in order to move the reversing switch to another position. As shown in the Figure the reversing switch comprises a bar g having three operative positions O, V, R, corresponding to forward, reverse and " off " motor circuits. On operation of the " forward " push-button q the electromagnet a is energized, the core b pulling the arm g upwardly by means of a spring n. A maintaining circuit for the electromagnet a is completed at " holding " contacts c and " locking " contacts f so that the reversing switch is maintained in this position. If now it is desired to move the reversing switch directly to the " reverse " position the push-button r is depressed and electromagnet d is energized. The core e can now move upwards by virtue of the lost motion m, l between it and the switch arm g and the maintaining circuit of the electromagnet a is broken during this movement by the separation of the " locking " contacts. Further movement of the core e then moves the switch bar g to the operative position R this movement being permitted by the elastic connection n between the core b and the arm. In a modified arrangement Fig. 2 (not shown), the reverse electromagnet completes a maintaining circuit through " holding " and " locking " contacts in the manner previously described in which arrangement both cores have lost-motion connections with the switching bar g. Other alternative arrangements are indicated in which a common core may be provided for the electromagnets and in which more than two electromagnets with a correspondingly increased number of switching positions may be employed. A " stop " push-button s is provided for breaking the electromagnet maintaining circuit or circuits and a handle p permits alternative manual operation.
