Title: Improvements in electrical tumbler switches
IPC: H01H23/20
Filed: 1922-04-27
Abstract: 194,968. Wynne, A. C. April 27, 1922. Switches, quick-action.-In tumbler switches, the quick-action spring mechanism is in two interconnected parts, the main part of which locks the switch arm " on " and " off," while the secondary part locates one of the abutments of the main part in a position that enables it to exert its locking thrust. The dolly a carries the secondary spring b which actuates a plunger c to which is pivoted at f<3> the link f carrying the main spring g. The link f is guided by a rocking piece c pivoted to the switch arm d which is itself pivoted at d<1>. In both positions, the spring b depresses the plunger c to enable effective locking leverage to be exerted by the spring g, while it can be seen from Fig. 2 that both springs are compressed to give a quick action. For positive actuation of the arm d, studs on the dolly a may engage projections on the arm d to move it.

Abstract: 506,633. Aircraft alighting - gear. GENERAL AIRCRAFT. Ltd., WILLIAMS, D. L. H., and CROCOMBE, F. F. Nov. 29, 1937, No. 11794/39. Divided out of 506,527. [Class 4] In an aircraft which includes alighting-gear having nose and main elements disposed respectively, for wardly and rear wardly of the centre of gravity of the air craft so that when resting on the elements, the tai of the aircraft is maintained clear of the ground, the nose element may be retracted wholly or partly into the fuselage by mechanism causing the mounting for the element to swing about an axis substantially parallel to the longitudinal axis of the aircraft. In one form, the wheel 14 is carried by a shock-absorber 16, 17 carried by a shaft 32 mounted in bearings in the aircraft structure. The wheel is retracted, on rotation of the shaft 32, by an electric motor 36 connected to the shaft through a reduction and worm gearing. The aperture in the fuselage through which the wheel passes may be closed by a sliding door. In a modification, two laterally-spaced wheels are simultaneously retracted on operation of an electric motor disposed between them.

Abstract: 647,890. Aerials. PHILCO CORPORATION. May 2, 1947, No. 11859. Convention date, June 7, 1946. [Class 40 (vii)] The directivity produced by a hollow wavedirective structure having a mouth and a principal axis of propagation, such as a spherical reflector, or a horn, as shown at 4 in Fig. 1, is modified by the addition of a plurality of waverefractive elements 9, 10 mounted in front of the mouth and spaced along the principal axis of propagation. Each element comprises a dielectric disc 9 and may include in addition a smaller metal disc 10. The discs are supported on a dielectric rod 13 and may be slidably mounted to facilitate adjustment of the radiation pattern. The spacing between elements approximates to a multiple of a quarterwavelength. The disc diameters may decrease with increasing distance from the structure. A modification, Figs. 3 and 4 (not shown), employs dielectric discs alone of varying thickness and spacing. The entire assembly may be enclosed in a protective dielectric cover.

Abstract: 1357681 Sensitized photoreactions; coated tubes CIBA-GEIGY AG 15 March 1972 [16 March 1971] 11950/72 Headings B1X and B2E [Also in Divisions C2 C3 and C5] Sensitized photoreactions are carried out by a process comprising irradiating the reactant in liquid or dissolved form in the presence of an insoluble sensitizer, the liquid phase being moved relative to the sensitizer, for example by repeatedly passing the liquid phase through a tube the inner wall of which carries a layer of photosensitizer material in the form of a film or embedded in a carrier film or by passing the liquid phase through a layer of powder or granules of photosensitizer material. Examples relate to conversion of cis 1,3-pentadiene to trans-1,3-pentadiene; conversion of 9,10 - dihydro - 9,10 - ethenoanthracene - 11 - carboxylic acid methyl ester to 8b, 8c-dihydro dibenzo (a,f) cyclopropa (c,d) pentalene-8d (4bH) - carboxylic acid methyl ester, cqnversion of maleic anhydride to 3,4 dimethyl cyclobut - 3 - ene - 1,2 - dicarboxylic acid anhydride, conversion of + limonene to 1,2,2 - trifluorotrichloroethane, by irradiation with a mercury lamp or lamps in the presence of specified sensitizer materials. In preparing the sensitizer, a reactor tube of glass may be coated with a copolymer of 95% acrylophenone, 5% divinylbenzene by a process comprising introducing an acetone solution of the copolymer into a rotating horizontal tube and evaporating off the solvent by means of infra red lamps. The coated tube is then dried. Similarly, reactor tubes may be coated with a copolymer of 90% vinyl phenyl ketone, 10% methacrylic acid methyl ester; with a polychalcone of 4,4'- diacetyldiphenyl ester and terephthaldialdehyde; with a polyimide of pyromellitic anhydride and 4,4'-diaminodiphenyl ether.

[Class 110 (ii)] The invention comprises an improved or modified meter of the type described in Specification 240,262, [Class 110 (ii)]. A vane wheel a is rotated by fluid passing an inlet 1 to an outlet 2. The shaft c may revolve with the rotor and drive a second shaft d by means of a coupling j, or the rotor may revolve on a fixed shaft. Ball thrust bearings p, q, are provided. A coloured disc is attached to the spindle d to indicate when the spindle is rotating. An alarm device comprises a plate y and metal balls x. When the spindle revolutions per minute fall below a predetermined figure, the balls contact with the plate and ring a bell z. The speed of revolution may be indicated by the flickering of a lamp aa. The plate may be adjusted by screws dd. Adjusting screws are also used to vary the positions of the guide plates n<1>, n<2>, which are located on opposite sides of a partition oo. The plate n<2> regulates the fluid stream which passes under the vane wheel without making contact with it. Sealing washers m, n, are pressed upwards by a spring k. Springs cc may be fitted to the arms supporting balls x. The plates n<1>, n<2> may be dispensed with and replaced by a fixed diverging circular nozzle.
