Abstract: 893,717. Dispensing liquids by gaseous pressure. SYNCRO-MIST CONTROLS Inc. Feb. 23, 1960, No. 6307/60. Class 102(2). [Also in Groups XVIII, XXIX and XXXV] Upon depression of an aerosol operating knob 52, Fig. 4, by an electric motor, the lower enlarged part of a valve stem 28 passes into a resilient annular ring 42 and seals off a chamber 62 in a valve housing 20 from the surrounding container whilst concomitantly an orifice 36 in the upper tubular part of the stem 28 passes through a resilient annular seal into the chamber 62 whereby the contents of the latter are discharged via a chamber 56 and a small bore 58. The valve stem 28 is normally loaded to open the chamber 62 to the tube 50 which extends to the bottom of the container. The aerosal need not be of the metering type. The container is held on a stand 66, 64, 70, Fig. 2, by spring arms 82, 84, the stand also supporting a self-starting inductor-type synchronous electric-motor 88, which, through reduction gearing. rotates a metal flap 100 anti-clockwise. As the flap 100 abuts the valve knob 52 it depresses the stem 28 but upon the knob 52 physically contacting the container the motor is stopped; after a delay of one-half of an alternating current cycle the relative polarity of the stator and rotor has reversed so that the motor also reverses and the flap 100 lifts from the knob and rotates clockwise until it is stopped by a part 72 of the stand whereupon it again reverses and approaches the knob for a further operation of the aerosol. This cycle of events continues whilst the motor is energized. (See also Group XXXV).

Title: Improvements in or relating to the production of abrasive tools
IPC: B24D3/08
Filed: 1943-04-29
Abstract: Abrasive tools and slabs are made by incorporating diamond dust or fragments in a bonding agent which functions as a secondary abrasive, consisting of a mixture of boron carbide and silicon carbide together with at least one metallic carbide chosen from the carbides of nickel, aluminium, chromium, tungsten, molybdenum, zirconium and titanium.  In a preferred method, a mixture of silicon carbide, boron carbide and aluminium oxide is heated in a reducing atmosphere to sintering temperature, thus converting the aluminium oxide to carbide.  This mixture is cooled, crushed, graded and then mixed with diamond dust, the bonding agent being present in at least four times the volume of the diamond.  This powder is then placed in the lower part of a mould of circular cross-section and a disc-like carrier of a soft metal such as aluminium is placed thereon, the underside of the carrier being fitted with a plurality of keys as described in Specification 559,785, [Group XXIII].  The whole is heated to 800 DEG C. to melt the metal and then allowed to cool in a press at about 1 ton per sq. inch.  The Provisional Specification describes also the use of a bond comprising the carbides of iron, or the oxides of boron, silicon or aluminium.

Filed: 1943-04-29
Abstract: 563,455. Fastenings. WILMOTBREEDEN, Ltd., STEPHENSON; C. H., and GOUGH, L. April 29, 1943, No. 6785. [Class 44] A spring-loaded bolt b for a vehicle, or other door, fastening is operable by an outside handle being rotated in either direction, but can only be operated by an inside handle when rotated in one direction. When the inside handle, attached to a spindle m, is rotated in the opposite direction it causes a locking plate r to move towards the side of the bolt and plate pegs t, on the plate r, in a position to prevent rotation of a cam f which has a pair of fingers, one of which bears on a shoulder i to withdraw the bolt. The cam f has a central boss h which extends through a slot c in the bolt b, the boss h having a square bore j to engage the spindle of an outside handle. The 'spindle m has a collar n provided with a circular recess o to accommodate a circular portion on the end of the cam' boss h. A lost-motion connection between the cam and the spindle m comprises a pair of projections p on the inner periphery of the recess o which lie in a pair of grooves q in the reduced portion of the cam boss h. A spring-loaded ball or other detent y, carried by the boss h, engages with either of a pair of recesses z in the adjacent part of the spindle m to hold the latter against accidental angular movement relatively to the cam f when the projections p occupy positions at the appropriate ends of the grooves q., The pegs tare slidably mounted in housings u on the locking piece r and loaded by springs v to retain the pegs in their retracted positions. Projections w on the periphery of the hole s in the plate r occupy grooves x formed around the circumference of the collar n. When the spindle m is moved to lock the bolt, the lost-motion connection p, q, between the spindle and cam f, allows such movement without affecting the cam. During this movement the grooves x cause projection w, and thus the plate r, to move laterally and place the pegs t in the plane of the fingers of the cam f.
