Title: Improvements relating to internal shoe drum brakes
Inventor: WELLS KENNETH JOHN
IPC: F16D65/56
Filed: 1964-04-06
Abstract: 1,095,043. Internal shoe-drum brakes. GIRLING Ltd. March 18, 1965 [April 6, 1964], No. 5072/64. Heading F2E. In an internal shoe-drum brake the brake shoes 10, 11 are applied by a lever 24 pivotally mounted by a pin 25 on one shoe 11 and acting on the other shoe 10 through a strut, formed by a screw-threaded portion 31 and a sleeve portion 28, of which the effective length is adjustable and which is adjusted automatically when the angular movement of the lever 24 is actuated by a flexible cable 26 and exceeds a predetermined value owing to wear of the shoe linings. The lever 24 carries a resilient finger 35 which cooperates with ratchet teeth on a nut 33 in screw-threaded engagement with a screwthreaded portion 31 of the strut such that if the finger 35 engages the radial face of a ratchet tooth before it reaches the end of its travel the nut 33 would be rotated angularly to adjust the effective length of the struts sufficient to take up the wear of the linings. When the brake is released the finger will ride over the ratchet teeth. In an alternative embodiment (not shown) the adjustment may be effected on the return movement of the lever, the finger riding over the ratchet teeth on the applying movement. In a further arrangement (not shown) the ratchet teeth may be formed on the periphery of an internally screw-threaded sleeve receiving the inner ends of two aligned, oppositely screw-threaded rods forming the strut.

Title: Improvements relating to thermo-electric generators
Inventor: BUCKLAND IVOR
IPC: H01L35/00
Filed: 1966-02-04
Abstract: 1,113,396. Thermo-electric devices. INTERNATIONAL NICKEL Ltd. 27 Jan., 1967 [4 Feb., 1966], No. 5078/66. Heading H1K. The hot junction between the two elements of a thermoelectric generator is provided with a coating which includes a catalyst capable of supporting catalytic combustion. When the coating is exposed to a fuel stream, e.g. in gaseous form, the junction is heated by the catalytic combustion. The elements may be P and N doped semi-conductors such as iron disilicide, alternative materials being lead telluride, lead tin telluride, bismuth antimony telluride, bismuth tellurium selenide, germanium telluride or germanium silicide. The elements may be joined directly or connected by a metallic bridge carrying the catalyst, which may be supported by an intermediate layer, e.g. of insulating material. Platinum is suggested as a suitable catalyst, being applied in liquid form as a solution of an organo-metallic compound in oils, and then being fired to decompose the compound and to leave a metallic film bonded to the surface. The junction surface may be complex in form, providing high thermal efficiency when coated with the catalyst.

Abstract: 234,423. PathÚ CinÚma, Anciens Etablissements PathÚ FrÞres. Nov. 5, 1924, [Convention date]. Kinematograph picture films.- The driving perforations 5 situated at the part 4 of the film which comes in front of the driving claw or claws when the film is inserted in the gate of the kinematograph apparatus have a length greater than that of the standard perforations 3 in the remainder of the film, but less than the stroke of the claw or claws, in order to increase the probability of the direct engagement of the claw or claws in these perforations, and thereby avoid damage to the film by the sliding of the claw or claws thereon until engagement occurs. The lower edges of the perforations are at a uniform distance apart throughout the film, and the length of the perforations 5 is the maximum compatible with the retention of strength in the film.

A caul plate for use in a laminating press comprises a core of sheet material, e.g. paper, impregnated with thermosetting resin and provided with a surface sheet of polypropylene (preferably biaxially oriented) polytetrafluoroethylene, polyvinyl fluoride or pigmented P.V.C. which is preferably, but not necessarily, bonded to the core sheet, e.g. whilst the thermosetting resin is being cured under heat and pressure. The impregnating resin may be a phenol, cresol, or melamine formaldehyde or an epoxy resin. The surface sheet may be embossed, e.g. to simulate woodgraining using wood as a master caul and may be treated by corona discharge to improve adhesion to the core. It may, however, be strippable from the core so that alternative finishes may be obtained. The Specification states that the films tend to shrink when heated and are thereby stretched across the core surface.

Abstract: 1447112 Moulding POST OFFICE 21 Jan 1974 [6 Feb 1973] 5792/73 Heading B5A [Also in Divisions F2 and H1] Apparatus for manufacturing a waveguide in the form of a tube (see Divisions F2 and H1) includes an elongate mandrel, drive means for moving the mandrel along its axis, means for applying an electrically conductive layer to the mandrel and further means for feeding fibres to the mandrel at fixed circumferential positions around the axis of the mandrel, at least one die through which passes the mandrel, &c., and means for feeding a bonding agent to the die to embed the fibres in the bonding agent. As shown, the apparatus comprises a mandrel 5 in sections connected by spigots and sockets 6 and previously covered with a conductive layer or helix wound from an electrically conducting wire of strip. The mandrel 5 is advanced to the right by driving devices 7 through guides 10 which cover housings 9 of glass fibres. The fibres 9 are laid lengthwise of the mandrel 5 in a layer 11 as it enters a layering apparatus 8. The mandrel 5 passes through a first chamber 13 evacuated via a pipe 14, through die 15, into a chamber 16 to which bonding agent is supplied through a pipe 17. After passing through another die 19, the mandrel 5 with its impregnated layer enters a rotary armature 23 carrying supply reels 21 which wind a helical layer 20 of fibres on top of the layer 11 of longitudinal fibres. Alternatively, the mandrel 5, &c. may pass through two oppositely-rotating armatures which wind two opposite-hand helical layers on top of the longitudinal layer 11, or through a plaiting machine. Subsequently, the mandrel 5, &c. passes through a further chamber 28 to which bonding agent is supplied under pressure, and through a final die 27. While the resin is still wet the waveguide is cut into sections and left on the sections of the mandrel 5 to dry, the mandrel sections subsequently being withdrawn. Alternatively the dies, &c. can be heated to effect cure of the resin while in the apparatus.

Abstract: 388,933. Feeling and coring fruit. BURNS, J. E., 1208, East Water Street, Syracuse, New York, U.S.A. Feb. 27, 1932, No. 5947. [Class 28 (ii).] A device for peeling or coring citrous fruit comprises a serrated strip 1 bent into circular form and secured to a framework 9, 28 to which the handle 6 is attached. The skeleton framework 9, 28 preferably outlines a spherical surface, or, in a modification, the teeth 4, 5 are actually cut on the edge of a hemispherical or half-hemispherical shell which is secured to the handle. As shown in Fig. 3, the strip 1 is of a diameter to effect the peeling of the fruit, but if coring is to be effected, another tool having a strip 1 of much smaller diameter is used, this strip being preferably secured at its abutting ends, by riveting, spot-welding or otherwise, to a strip which is bent at two points to connect to a handle arranged coaxially with the strip 1. The serrations are preferably arranged in sets 4, 5 having different or opposite inclinations. In a further modification, Fig. 10, the strip 1 is adjustable in diameter by securing one end to a member 20 and the other to a member 29, the members 20, 29 being relatively adjustable. Locking of the members 20, 29 in the adjusted position is effected by clamping the pivot connection 21 with an internally screwed operating handle. The overlapping portions of the members 20, 29 may be roughened to increase the locking action.
