Title: Improvements in or relating to timing devices
Inventor: PHILLIPS KENNETH RICHMOND
IPC: G04F3/02
Filed: 1962-10-22
Abstract: 985,182. Time alarm signals. S. SMITH & SONS (ENGLAND) Ltd. Jan. 3,1964 [Oct. 22, 1962], Heading G3T. [Also in Division H2] A timing device for operating an alarm or an electric switch, and of the kind in which a spindle 1 is rotatable by hand from a datum position to a desired angular position to wind up a spring 3 attached to the spindle and on release is returned by the spring under the control of a timekeeping escapement 19,37, is characterized by cam and co-operating cam follower means driven by the device and arranged to disconnect the escapement over predetermined ranges of angular positions of the spindle,whereby during the return movement periods of rotation at the speed set by the escapement alternate with periods of more rapid rotation. The alarm or switch (not shown) is intended to be actuated by the spindle during the periods of rapid rotation. A first gear wheel 6 frictionally mounted on spindle 1 drives the escapement through the train shown. The balance 37 with pallet pins 21, 22 has one end journalled in one arm 39 of a lever 12 pivoted at 29,this lever being biased by a spring 27 so that the pellet pins normally engage the escape wheel 19. Another arm 40 of the lever is engaged by lobes 10, 11 of a cam 9 carried by an intermediate spindle 36 of the train so as to disconnect the escapement at intervals. The device may be made so that the pellets are moved to engage through the cam and are moved to disengage through the spring. Instead of frictionally mounting the wheel 6, the pinion 13 engaging this wheel may be of the "kick-out" type to allow the winding movement. Specification 968,587 is referred to.

Abstract: 932,219. Magnetic storage apparatus. GENERAL ELECTRIC CO. Ltd. Feb. 21, 1962 [Nov. 25, 1960], No. 40635/60. Class 40 (9). In a storage matrix in which magnetic thin film areas 1, Fig. 1, supported by a glass or aluminium substrate 2 are associated with coordinate sets of drive conductors (not shown), looped pickup conductors 4, 5 are arranged parallel to the respective drive conductors of one co-ordinate set in such manner that each pickup conductor portion 4 overlies a different row of thin film areas, and the other conductor portion 5 is intermediate adjacent rows of thin film areas, the looped pickup conductors being positioned wholly on one face of the substrate and film areas. In one arrangement, Fig. 2, the pickup conductors 4, 5 are deposited on an insulating layer previously formed on the substrate and film areas, and are perpendicular to the magnetic easy axis 3. One set of co-ordinate drive conductors 6 is photo-etched on a thin sheet 7 of polyethylene terephthalate which is folded over the substrate to provide drive conductors on both sides. A similar unfolded sheet may be used for the pick-up conductors as an alternative. The other set of co-ordinate drive conductors 10 is printed on boards 8, 9 which are located on opposite faces of the substate assembly, the printed strips being connected at one end to form parallel loops. A three coordinate matrix using inhibiting windings is shown in Fig. 3. Four partially wound planes 12a-12d are shown. To register a binary word in a particular vertical location, a selected pair of drive conductors 6, 10 which extend through each plane are pulsed simultaneously by sources 18, 19. Those planes in which a binary zero is to be written are inhibited by a coincident pulse from selected sources 20a-20d, the inhibit winding as shown in plane 12c being printed in two boards 16, 17 connected so as to form a flattened helical winding surrounding all the storage areas. Writing is completed by termining one driving pulse before the other so that the correct directions of magnetisation along the easy axis are taken up. An appropriate pair of drive conductors 6, 10 are pulsed to read a stored word, gates 15a-15d in the pickup conductor circuits 13 being opened momentarily. A single storage element for a two-core-per-bit store is shown in Fig. 4 in which the co-ordinate drive conductors comprise a strip 27 and a loop 26, each portion 24, 25 of the loop being associated with a different film area 22, 23. The pickup conductor 30 forms a double loop and has one portion 28 of the conductor portions 28, 29 in operative association with the magnetic thin films. Alternatively a single film area may be used as a two-core-per-bit store, the film area being positioned below portions 29 only of the pickup conductor. Specifications 905,340 and 928,847 are referred to.

Abstract: 1,171,131. Coating. DYNAMIT NOBEL A.G. 13 Sept., 1966 [14 Sept., 1965], No. 40950/66. Heading B2E. [Also in Divisions B5, B6 and E1] A surfacing material for applying to a substrate comprises a first layer of a synthetic plastics material and a second layer of a thermoplastic polyurethane whereby the surfacing material can be adhered to a substrate, the first layer having applied thereto a granular material to provide a rough wear-resistant surface. The surfacing material can be adhered to a substrate, such as asphalt, bitumen, concrete, wood or metal, e.g. steel, optionally using suitable adhesives such as an epoxide resin. The material may be in strip form. Suitable thermoplastic polyurethanes are disclosed. The granular materials may be sand, quartz, corundum, silicon carbide. The first layer may also comprise glass beads as reflectors, dyestuffs and pigments such as titanium dioxide. The synthetic resin may be a cold setting or thermosetting epoxide resin optionally containing a flexibility imparting agent, or polyvinyl chloride or a polyurethane to which conventional plasticisers have been added. A foil of thermoplastic polyurethane may be coated by pouring on or trowelling a composition consisting of a curable epoxide resin, a flexibility agent, a hardener, a filler. Granular material is then scattered on to a layer of the epoxide resin hardener mixture and rolled in. The epoxide resins preferred are those which are liquid at ambient temperatures, and suitable compounds are listed. Examples of flexibility imparting agents and hardeners for the epoxide resin binders including hardening agents having a curing action on the binder are also given. Accelerators for the hardening of the binder may be used and examples are given. A solution of the thermoplastic polyurethane may be applied to a foil of polyvinyl chloride containing a filler incorporated during the formation of the foil by extrusion or calendering and material of desired grain fraction may be incorporated by rolling into the surface of the foil. That surface not so provided with granular material may be treated with the polyurethane solution. Alternatively, the foil may be coated by immersion in the solution; the surfaces sanded and coated again with the polyurethane solution. A foil of thermoplastic polyurethane may be coated on one side with a pigmented polyurethane solution and granular material scattered thereon, the process then being repeated. The amount and grain size of the granular material can be varied, and a mixture of grain sizes of up to 1 mm is preferred. The first layer may have zones of different degrees of surface-roughness by using different granular materials or materials of different granulation, and may have different areas comprising a different pigment or dyestuff. The surfacing material can be used for producing "zebra crossings" surfacings for boat decks, landing stages, jetties, roadways and road markings.

Abstract: 1320820 Thermocouples FORD MOTOR CO Ltd 7 Sept 1971 [12 Nov 1970] 41600/71 Heading H1K In order to prevent stressing of thermocouple wires embedded within a housing, spaces are provided round the wires by covering them near to, but not at, the junction with a sheath of thermally degradable material, placing the thermocouple in the housing, filling with an encapsulating material, and then heating to degrade the sheaths. The sheaths are of a material which reduce in solid volume when heated either by decomposing or by shrinking. In a first embodiment, Fig. 1 (not shown) and Fig. 2, the ends of two thermocouple wires 12, 14 are joined to form a junction 16 and are covered with degradable sheaths (18). The sheathed wires are loosely twisted and placed in a metal housing 10 and encapsulating material 20 is packed into the housing and cured. The tip of the housing is swaged to reduce its size and the assembly is heated to degrade the sheath material and form channels 24 round the thermocouple wires 12, 14 so that they can expand and contract during thermal cycling. Further encapsulating material 25 is applied to the open end of the housing to seal the wire entry. In a modification, Fig. 3 (not shown) only the lower parts of the wires are sheathed with degradable material, the upper parts being sheathed with thermally stable material so that the encapsulating material can seal directly to the stable sheaths. If the degradable material emits gases the casing is only partially filled with encapsulating material before heating so that the gases can escape. In another modification, Fig. 4 (not shown), the whole of the lengths of the wires are sheathed with thermally stable material and the lower parts are then provided with an outer sheath of degradable material. Suitable materials for the stable and degradable sheaths and for the encapsulating material are mentioned. The thermocouple wires may be of Ni-Cr and Ni-Al alloys and the junction may be in contact with the end of the sheath.
