Abstract: 1458879 Fluid dispensing apparatus PAN-NOVA Inc 24 Dec 1974 [26 Dec 1973] 55842/74 Heading A4T [Also in Division G4] A fluid dispensing apparatus comprises a first compartment 10 with a fluid inlet line 14, a flowmeter 15 and an outlet line 19 to a nozzle 20, and a second compartment 11 isolated from the first compartment with a light source 35 feeding along a pair of fibre optic paths 37, 39. The first path 37 can be interrupted by a lever 27 which is moved out of the path when the nozzle 20 is removed from a holder 26. The second fibre optic path 39 includes a disc 24 provided with alternate opaque and transparent segments. The disc is rotated by an outputshaft23ofthe flowmeter 15 to provide pulses to a light sensor unit 40. The disc 24 may cause four hundred segments to pass through the light path per gallon. A token acceptor 46 has a light sensor 47 so that the light path is interrupted each time a valid token or coin is accepted. The price and logic system of the dispensing apparatus enables the price per gallon 51, the gallonage 52, the deposited coin value 53, the amount of sale 54 and the amount of change due 55 to be displayed. The apparatus may be stopped before the full gallonage has been dispensed and the necessary change returned. Also the apparatus is stopped if the vehicle tank becomes full before the gallonage has been dispensed and change given. The apparatus has four lamps on its front panel to indicate "insert nozzle", "deposit tokens", "push START", and "fill tank". The apparatus can accept coins, tokens or paper money or be actuated by a push button to produce the required electric signal. Specification 1458880 has identical description but the claims relate to the logic control circuits.

Title: Surge voltage diverters

Filed: 1971-12-06
Abstract: 1319924 Cold cathode discharge tubes SIEMENS AG 6 Dec 1971 [8 Dec 1970] 56470/71 Heading H1D A surge diverter comprises two main electrodes 1 each of which defines a main discharge gap 5 with respect to an earth electrode 2, the two main electrodes also defining a secondary gap 6 having a lower breakdown voltage than the main gaps 5. The lower breakdown voltage may result from the shape and spacing of the electrodes and/or the activation of their discharge surfaces. The intended use of the diverter is with each of a pair of lines connected to a respective main electrode so that an overvoltage on one line will be discharged to earth and any consequent cross voltages on the pair will discharge across the secondary gap. Alternative constructions are with coaxial cylindrical main electrodes surrounded by a coaxial hollow cylindrical earth electrode, Fig. 1 (not shown); and a pair of flat electrodes with a partially intervening flat earth electrode, the main electrodes being brought closer together at one portion to form the secondary gap, Fig. 2 (not shown).

Title: Production of expanded olefin polymer moldings
IPC: C08J9/236
Filed: 1967-12-15
Abstract: 1,201,800. Moulding expanded polyolefin. BADISCHE ANILIN- & SODA-FABRIK A.G. 15 Dec., 1967 [16 Dec., 1966], No. 57042/67. Heading B5A. [Also in Divisions B2 and C3] Expanded olefin polymers, preferably having an X-ray crystallinity greater than 25% at 25 C., are moulded by the compression of expanded particles thereof, either before being introduced into, or within, a mould, by a gas, e.g. air or nitrogen or chlorofluoro carbon compounds, whereafter the gas pressure is released so that the particles expand to fill the cavity. If compressed in a mould, the volume of the cavity of the mould is then decreased to 90 to 40% of the original bulk volume of the particles and the pressure in the mould is then decreased, e.g. to atmospheric or below to permit the particles to expand and bond together, either by fusion or by an adhesive coating applied to the particles; in the former case the particles may be heated either prior to introduction, or in the mould. In a first example, the mould cavity 5 is preheated to 100 C. by a hot air line 1, expanded particles of ethylene polymer containing polymerized units of tertiary-butyl acrylate are conveyed, via line 3, whilst being heated to 95 C., into the cavity 5. Air at 80 C. is introduced via valve 6 to a pressure of 2À5 atmospheres, a plunger 8 is lowered to decrease the cavity volume, whereupon valve 6 is opened to decrease the cavity pressure to atmospheric. An ethylene/isobutylene polymer mixed with polyisobutylene may similarly he moulded at a temperature of 125 C. and 5 atmospheres. In a second example, Fig. 2 (not shown), low density polyethylene particles are coated with epoxy binder in a vessel (9) from which they are admitted to a cavity (5) into which air at 70 C. and 3 atmospheres is then introduced. After releasing the internal cavity pressure, air at 70 C. is circulated through the cavity to cure the binder. In a third example, Fig. 3 (not shown), particles of ethylene copolymer containing polymerized butyl acrylate and acrylic acid units are pressurized in a container (12) to 105 C. and 6 atmospheres before admission to a mould wherein pressure is then restored to atmospheric. Details are also given of the method of the second example as applied respectively to polypropylene, high density polyethylene, and a mixture of an ethylene/isobutylene with polyisobutylene employing respectively, as binders, bitumen, a mixture of diethylene glycol and toluylene di-isocyanate, a dispersion of polyisobutylene in water. Details of other suitable polymers are given (see Division C3). The expanded particles are preferably of 3-40 mm. diameter and may be produced by extrusion/cutting of a composition containing expanding agent, or merely by heating thereof. The particles may also contain flame-proofing agents, dyes, fillers or lubricants and wood or thermoplastics fibres. Fabrics or netting reinforcements, e.g. of thermoplastics, may also be incorporated in the mouldings. The expanded particles may contain cross-linked constituents.

A tippler for tippling a barge 64 and discharging it on to endless conveyer 50 and thence on to endless discharge conveyer 62, is formed of two part-circular floats 10 joined by rails 12, 14, 16 and driven from motors 44 and the gearing shown via curved racks 42 formed on tanks 10. The tippler turns about shafts 18 carried by beams 22, 24 mounted pivotally on fixture 30. Operation.-The barge 64 is floated on to rails 12 and the tippler then is swung anticlockwise so that the barge is pressed upwards by the rails 12 whilst leaning against the rails 14 and 16 and discharges the material on to the endless conveyer 50. The discharge is assisted by the fact that as the tippler rotates anticlockwise the proportion of the two tanks 10 which is positioned beneath the level of the water shows increases, so that the downward movement of the beams 22, 24 under weight is minimized.

Abstract: 1,148,630. Winding coils; wrapping terminals. GENERAL MOTORS CORP. 22 Dec., 1966 [27 Dec., 1965], No. 57454/66. Headings B3A and 53E. A method of automatically winding a wire coil on to a bobbin and electrically connecting the coil to terminals carried by the bobbin comprises mounting the bobbin on a displaceable support for movement through a series of work stations, moving the bobbin to a first work station adjacent a supply of said wire, guiding a first portion of said wire about a first terminal of the bobbin, winding the wire about said bobbin, guiding a second portion of the wire about a second terminal and advancing the bobbin to a second station and cutting and wrapping said wire about the terminals at said second station. Coil bobbins 24 to be wound each comprise a flat central part 25, which may house a rotatable magnetic armature, and four corner parts of which two, 27, 29, are provided with metallic terminals 30, 32. The wound bobbins may be used in electrical gauges. The bobbins 24 to be wound are held in arms 12-22 on a table 10 and are carried thereby through six working stations. At one station a coil of enamelled wire 38 is wound about the bobbin 24 by a rotatable flyer 34. Prior to such winding a guide 40 is moved down to the terminal 32 so that the wire is guided behind it and after winding a guide 42 moves the wire extending to the flyer 34 to the terminal 30 so the wire is guided around this terminal when the bobbin is moved to the next station. Insulation is burned from those portions of the wire to be engaged by the terminals by gas torches 44, 46. Two stations further on the wire is cut off and wrapped around the terminals 30, 32 by rotated tools 48, 50 lowered by air cylinder means and co-operating with a lower cut-off die 52 raised by air cylinder means. At the next station the wound bobbin is removed to be replaced by an empty bobbin.
