IPC: H01H9/10
Filed: 1930-10-09
Abstract: 364,196. Snap - action switches; switch bases and covers. PRESTON, W., Falcon Electrical Works, Redding Lane, Wednesbury, Staffordshire. Oct. 9, 1930, No. 30225. [Class 38 (v).] The contact-carrier 3 of an electric multi-pole switch is in the form of a roller and is rotatably mounted at its ends in semicircular recesses in the base 1 and cover (not shown). The combined contact arms and fuse carriers 8 are pushed through holes in the carrier 3 and held in place by a spring-biased pin 10, and the two contacts of each pole are separated from each other as well as from the contacts of the adjacent pole by co-operating longitudinal and transverse webs formed in the base and cover. The switch is operated by a co-axially mounted rotary handle 18 through an intermediate U-shaped pin 20 controlled by a dead-centre spring 21. The two ends of the pin 20 engage sector-shaped recesses in the handle 18 and carrier 3 respectively so that the necessary lost motion between the parts is provided. The Provisional Specification refers to Specification 363,442.

Title: Improved process for the purification of naphthalene
IPC: C07C7/14
Filed: 1920-11-15
Abstract: Crude naphthalene is purified by agitating in a tank with a non-miscible liquid at a temperature slightly above the melting point of the former and then gradually cooling the whole.  The liquid may be added either before or after melting the naphthalene, and the cooling effected either by radiation or by addition of cold liquid. Crystals are deposited and are separated by centrifuging, filtration, &c.  In an example, water is used as the non-miscible liquid.  The Specification as open to inspection under Sect. 91 (3) (a) includes the purification in a similar manner of fluorene, acenaphthene a-naphthylamine and aromatic compounds generally. This subject-matter does not appear in the Specification as accepted.

Abstract: 174,726. Bush, H. D., and Merton, H. Oct. 30, 1920. Shaft couplings.-In means for indicating or producing, by fluid pressure, a variation in angular relationship between two aligned rotary members, the fluid-pressure device is in the form of a non-rotating annular piston and cylinder in endthrust engagement with the two rotary members, which directly engage one another by screwthreads. When used as a torque-dynamometer, the engine to be tested is coupled, for example by rods sliding in orifices 14, to the rotary member 4 engaging by 45‹ screw-threads 5 a shaft 1, to which is keyed the other member 2, similarly coupled bv sliding rods to a calibrated air-screw or other brake. The parts 2, 4 thrust respectively by antifriction bearings 9, 10 against an annular chamber and piston 7. The chamber 6 is filled through an orifice 12 with fluid, such as thin lubricating-oil, and is fitted with a pressure-gauge 11, which may be graduated to give torque readings directly. The apparatus may be put out of action by screwing up a nut 15. Means may be provided for varying the quantity of fluid in order to change the angular relationship of the parts 2, 4, in which case the piston may be doubleacting, so that motion is positive in both directions.

Abstract: 603,982. Optical-projection apparatus. GILLARD, F. G., WARD, S. A., and FOOT, W. A. Nov. 19, 1945, No. 31102. [Class 97 (i)] A film strip projector has a film-feeding device including a container for a coiled film and means to guide the inner end of the film out from the container in a direction inclined with respect to the axis of the film coil. In the form shown, the front wall 17 of the lamphouse supports a casing 20 rotatably mounted thereon at 21 and supporting the condenser lens elements 18. Attached to the front of the casing 20 by a hinge at one side is a housing 23 having the projection lens 24 at its forward end and a glass plate 42 forming part of the gate at its rear end. A variable masking device has blades 27 which may be relatively adjusted by a cam operated by an external knob. The rear gate member is a glass plate 43 in a holder pivoted at 57. Film is fed by a sprocket 52 and the plate 43 is lifted during feeding by a cam concentric with the sprocket. The sprocket and cam are frictionally connected and may be relatively adjusted to frame the projected image. The axis of the film feed container 31, on base 30, is inclined both to plane of gate and to the vertical plane through the optical axis. The innermost turn of film is twisted and pulled through a slot 33 in the base 30. The take-up film container consists of two circular flanged plates 36, with flanges facing, normally parallel and spaced apart by approximately the film width but hinged to be capable of movement apart to withdraw the film. Slides in vertical guides 40 may be projected when the plate 43 is retracted. For this purpose a carriage 44, on which the sprocket 52 and the pivot 57 are mounted, slides in guides 46 against the action of a spring 144, when actuated by a lever 47, pivoted at 48, and operated from an external knob by a crank 50.

[Class 40 (v)] Sub-modulation systems of the kind described in Specifications 146,988, [Class 40 (v)], and 379,305 are characterized by the feature that the modulating current is applied both to the sub-modulation frequency and to the main carrier-frequency. As shown in Fig. 14, the carrier-wave generator 10 is choke-modulated by a sub-carrier generated by the valve 8, which is also choke-modulated by currents from a microphone 1 after amplification by a valve 6. Simultaneously the amplified microphone currents are applied from the secondary winding 40 of the transformer through a lead 381 direct to a tapping 36 in the grid circuit of the carrier-generator 10, giving rise to the wave-form shown in Fig. 8. The tapping point 45 on the grid of the subcarrier oscillator 8 may also be connected directly to the lead 38<1>, so that that valve is also grid-modulated by the amplified microphone currents, giving rise to the wave-form shown in Fig. 9. The percentage modulation may be adjusted in each case.

Title: Purification of tungsten by recrystallization of normal alkali metal tungstate as the paratungstate
IPC: C01G41/00
Filed: 1955-11-02
Abstract: Alkali metal (including ammonium) tungstates are purified by forming a saturated alkaline solution of a normal alkali metal tungstate containing undissolved normal tungstate, acidifying to pH of 7 to 7.5 to dissolve the normal alkaline metal tungstate crystals and further acidifying the solution to a pH of 6 to 6.9 to crystallize the corresponding alkali metal paratungstate. Acidification is preferably effected at 80-100 DEG  C. with hydrochloric acid; a small amount of sodium nitrite may be added to avoid reduction of the tungstate during acidification.  The alkali metal paratungstate crystals obtained on cooling may be treated with a calcium chloride solution to form calcium tungstate.
