Title: Improvements in electric circuit breakers of the gas blast type
IPC: H01H33/867
Filed: 1942-04-03
Abstract: 558,559. Gas-blast switches. ENGLISH ELECTRIC CO., Ltd., BLANDFORD, A. R., and ROWLAND, F. G. April 3, 1942, No. 4504. [Class 38 (v)] A gas-blast switch of the kind in which the movable contact is moved directly by the blastgas into an enclosure shut off from the circuitbreaking chamber against the force of a spring, the blast then flowing between the contacts and away from the enclosure, has the current led to the movable contact by fixed rubbing brushes which, together with the biasing spring, are housed within the enclosure. In a doublebreak arrangement, the movable contacts are arranged back-to-back in a common enclosure, and an impedance may be connected in parallel with one of the breaks, and an additional pneumatically-actuated, sleeve-like contact may shunt each of the arcing contacts for extraheavy current working, such additional contacts being operated before the arcing contacts, Fig. 1 (not shown). In the single-break switch of Fig. 2, a fixed nozzle-contact 3 is mounted in a sleeve 12 having an annular recess in which can slide, under the action of the blast-gas and against spring-action 13, an additional flanged garter-spring type of contact 11, 14 which normally is in parallel with the contact 3, and companion contact 6. The latter is formed with apertures 6b, 6c, and is cup-shaped and slidable in a housing 17 against spring-action 10, connection between it and the housing 17 being by means of the garter-spring contact 8. The blastgas flows as shown by the arrows, operating first contact 14 and then contact 6, and it can be seen that the springs 10, 13 and garter-spring contacts 8, 14 are always protected against the archeat. A mechanically-interlocked series-isolator may be provided. Specification 545,953 is referred to.

Abstract: Styrene or a nuclear alkyl or halogen substitution product thereof is copolymerized with an aromatic petroleum residue by heating, e.g. under reflux or pressure.  The residues are unsaturated products obtained by the extraction of mineral lubricating oils or crude kerosene with selective solvents, e.g. by the Edeleanu process, and are sold under the names "Dutrex," "Edmor" and "Iranolin" (Registered Trade Marks). Polymerization may be carried out in solution in xylene or dipentene, if desired in the presence of sulphur, a mono-cyclic a -terpene or a soap-forming acid, e.g. rosin.  Alternatively, the soap-forming acid and also solvents, pigments and fillers may be added to the product.  The reactants may be added continuously or intermittently.  The products vary from viscous oils or balsams to brittle resins and may be partially soluble in petroleum ether. In an example (7), styrene, aromatic petroleum residue and rosin were refluxed for 6 hours.  The product on treatment with aqueous sodium hydroxide or ammonia formed an emulsion, from which the solids deposited on drying.

Abstract: 370,124. Mercury switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Walker, W. R. ; Short Hills, New Jersey, U.S.A.) Feb. 19, 1931, No. 5284. Convention date, Feb. 20, 1930. [Class 38 (v).] In order to provide a sealing-closure for vitreous envelopes such as those of electric switches of the fluid flow type, and more particularly mercury switches, a metal member having an opening therethrough is sealed into the envelope, after which the opening is sealed hermetically. Fig. 1 shows a mercury switch wherein an envelope 1, which may be of fused silica, or one of the materials known under the registered Trade Marks " Pyrex " or " Nonex," or preferably a softer glass such as lead or lime glass, is provided with cup-shaped electrodes 2, 3, the walls of which are fused into the material of the tube 1 and are bevelled to facilitate the sealing. An aperture 4 through the electrode 2 is screw-threaded to receive a tubular conductor or lead 5, for example of nickel, which is screwed therein and preferably soldered or welded to ensure a hermetically sealed joint. The tubular lead 5 provides an opening through which the envelope may be evacuated and mercury 7 admitted. An aresuppressing atmosphere, which may be of several atmospheres, may be admitted through the tubular lead, which is subsequently sealed by welding at a point 6, preferably after the application of a mechanical force to press the walls together. The electrode 3 may be apertured similarly to the electrode 2 or, as shown, may have a screw-threaded recess to receive the threaded end of a lead 5<1>. In a modification the tubular exhausting-stems are formed integrally with the electrodes. For use with heavy currents, and to withstand high temperatures, a glass such as a boro-silicate glass is used which, having a coefficient of expansion materially lower than that of chrome iron, is sealed to the electrodes by a graded seal. The Specification as open to inspection under Sect. 91 (3) (a) describes also modifications of the construction of the electrodes, wherein chrome-iron cup-shaped members without exhausting or sealing apertures are adapted to be secured to the connecting-leads by screwthreaded shanks or by soldering. This subjectmatter does not appear in the Specification as accepted.

Filed: 1931-02-20
Abstract: 384,277. Coin-freed weighing-apparatus. BARNES SCALE CO., 6521, John R. Street, Detroit, Michigan, U.S.A.-(Assignees of Barnes, H. W.; 15805, Baylis Avenue, and Winkler, H. G.; 3502, Sheridan Avenue, both in Detroit, Michigan, U.S.A.) Feb. 20, 1931, No. 5336. Convention date, Feb. 20, 1930. Void [Published under Sect. 91 of the Acts]. [Classes 27 and 143.] A personal weighing-scale is provided with a frusto-conical chart 22 that is read through a cylindrical lens 7 situated in an aperture in the upper plate 5 of the housing, the plate 5 and the upper curved surface of the chart being arranged at about 30‹ to the horizontal and thus approximately normal to the line of vision of the person being weighed. When a person steps up on to the platform, the draw-rod 15 and a member 18 are depressed against the action of springs through a distance proportional to the weight of the person. A weighted rack bar 40, meshing with a pinion on the indicator shaft and normally resting on the member 18, is prevented from following the member by a pawl 42 in engagement with a ratchet wheel 33 on the indicator shaft. Upon the insertion of a coin 47 into a shoot 48, a lever 43 is rocked to disable the pawl and allow the indicator to rotate under the weight of the rack bar. The coin is held in operative position by a weighted pawl 50 that is rocked to release the coin when the person steps off the platform. For this purpose the pawl 50 is provided with a tooth 52 that co-operates with a ratchet 53 pivoted to an arm 55 of the drawrod. The indicator is returned by a suspended weight 31. A blade spring 63, divided into two parts 64, 65, serves to give an initial impetus to the rack-bar and thereafter to brake the movements of the indicator shaft.

Title: Improvements in devices for stabilising the resonant frequency of cavities, as a function of the temperature
IPC: H01P7/06
Filed: 1966-02-07
Abstract: 1,125,894. Resonant cavities. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCH. KISS BRANDT. 7 Feb., 1966 [12 Feb., 1965], No. 5346/66. Heading H1W. A cavity resonator is compensated for changes in resonant frequency due to temperature variations by means of an independent piston supported upon members which are deformable under the influence of the temperature variations. As shown, a cavity 601 of the re-entrant type (part only shown) is tuned by axial movement of the re-entrant portion 602 which, for this purpose, is threaded into a radially compressible collar 609 carrying an internally bevelled lock-nut 616. A coaxial temperature-compensating piston 604 is carried upon a rod 607 screw-threaded into a guiding member 606 which slides axially within the tuning piston 602. The axial position of member 606, and hence of the piston 604, is determined by the length of three tubular temperature-responsive liquid-filled bellows 610 (two only shown) against which the member 606 is pressed by a spring 614. The end of the rod 607 is located by a flexible blade 671. Guiding member 606 is positively connected to the piston 602 by the bellows 610 so that rotation of the piston causes rotation of member 606 and axial movement of rod 607. Hence, the penetration of the piston 604 #e varies with the penetration a of the tuning piston 602. The resulting variation in compensation sensitivity with resonant frequency can be made to follow a given linear or other law by suitably choosing the pitches of screw threads 661, 631. In a modification, the bellows are replaced by stacks of arcuate bi-metallic elements (512, Fig. 5). In another embodiment the two pistons are manually and independently adjustable.
