Title: Improvements in Automatic Signalling Devices for Attachment upon Vehicles.
Inventor: JOECK THOMAS DUDLEY
IPC: B60Q1/44
Filed: 1917-12-07
Abstract: 121,989. Joeck, T. D. Dec. 7, 1917. Road traffic signals on vehicles.-When a vehicle slows up, the circuit of a signal lamp is automatically closed by means operated by the inertia of a pendulum or other body carried by the vehicle. In the form shown in Fig. 1, a pendulum 12 is connected to a trailer weight 25 supported by a contact roller 27. While the vehicle is at rest or travelling at a uniform speed, the roller 27 rests on insulation 15, but when the vehicle slows up, the pendulum 12 and weight 25, owing to their inertia, move into the position shown in dotted lines, the roller 27 closing the circuit of a lamp 8 by engaging contact 16, which is preferably inclined so as to help return the pendulum and weight to their normal positions. In a modification, the weight 25 is supported by a system of links and is retained in its normal position by a spring. In a further modification, a brush carried by the pendulum rod engages a fixed contact when the pendulum moves relatively to its casing.

Filed: 1936-02-21
Abstract: 472,388. Wrapping-machines. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Feb. 21, 1936, No. 18248/37. Divided out of 472,314. [Class 94 (i)] The machine produces wrappers provided with tearing strips, e.g. of the kind described in Specification 437,207. According to the invention, a continuous narrow strip is fed into predetermined adherent engagement with the web of wrapping material, and a series of loops is formed in the tearing strip, so that on severance along a line coinciding with one end of each loop, a series of wrappers is formed and the extra material provided by the loop enables the strip to project from the edge of the wrapper. A web 10 is fed around a roller 35a to a pressure roll 13 which applies it to a drum 14 rotated as described in Specification 472,314. A thin line of adhesive is applied to the web by the periphery of a gumming wheel 32. The tearing strip is fed round a roll 44 on to the drum, and is formed into loops by a roller 45 having a projection 46 forcing the material into recesses 47 in the drum. The loops are retained by fingers 48, Fig. 3, which are moved into the recesses by cam action in a direction parallel to the axis of the roller 45. The recesses are arranged between slots 42 which accommodate knives 40 on a roll 26 for forming the cuts 41, Fig. 5, on each side of the strip. A heating device 36 ensures adhesion of the strip to the web. Knives 27 sever the web along the line 54 in separate wrappers, the line of severance coinciding with the ends of the cuts 41 and one end of the loops 52. When the loops are flattened they project beyond the ends of the wrappers.

Title: Improvements in the manufacture and production of oxygenated products from hydrocarbons or oxidisable derivatives of hydrocarbons
IPC: C07D307/60
Filed: 1925-11-11
Abstract: 263,201. Caspari, W. A. Nov. 11, 1925. Aldehydes, ketones, carboxylic acids and anhydrides.-Hydrocarbons or their derivatives are oxidized by heat treatment in the vapour phase with air, using certain catalysts in the form of a smoke or aerosol. The catalysts comprise the oxides of metals of the fifth and higher groups, e.g. the oxides of vanadium, molybdenum, tungsten, chromium and uranium. A colloidal suspension of the catalyst in the liquid or molten starting material is first prepared by the use of a colloid mill or by forming an are in the liquid between electrodes of the catalytic material, and the suspension is then sprayed with air into a heated oxidizing chamber in which more of the catalyst may be present in a fixed condition. The production of the aerosol may, if desired, take place in a preheating chamber at a temperature below the reaction temperature. The products are condensed from the issuing gases and the catalyst recovered. Examples are given of the production of benzaldehyde and benzoic acid from toluene, of maleic anhydride from benzene, and of phthalic anhydride with naphthoquinone from naphthalene, using vanadium oxide as the catalyst in each case.

IPC: B60R25/042
Filed: 1961-05-23
Abstract: 967,497. Preventing unauthorised use. D. BOYELL, and E. P. BROWN. Aug. 3, 1962 [May 23, 1961], No. 18510/61. Heading F1B. In an anti-theft device comprising a fuel cut-off valve movable by a control device 20 from a fuel cut-off position, in which it can be locked by e.g. a combination lock 18, to a normal open position, movement of the valve operating member 24 beyond the normal open position operates a second fuel cut-off device 40 which cannot be released by operation of the control device 20. The valve 36 is controlled by a sliding plunger 24 operated from the knob 20 by a Borden cable 22, the valve device 12 being mounted in the inlet pipe 13 of the fuel pump 15. The Borden cable runs with clearance inside a tube 26 sealed at both ends. When the vehicle is parked, the knob 20 is pushed in to move valve 36 on to its seat 35 and the lock 18 is set. To reopen the fuel supply, the lock 18 is released and knob 20 pulled out to move the member 24 and valve 36 to the position of Fig. 2. If an unauthorised person attempts to operate the device 12 by cutting through the tube 26 and pulling cable 22, the member 24 will be moved beyond its normal open position to the position of Fig. 3 in which a ball 40 loosely fitted in bore 41 drops out into a valve seat 39 and cuts off the fuel flow. In this position the ball cannot be released by the member 24. A normally compressed spring 44 may be provided to force the ball 40 towards seat 39. Cutting of the tube 26 also admits air therethrough into the pump inlet and thereby assists in cutting off the fuel delivery. In a modification a single ball valve performs the function of the two valves 36, 40. In Fig. 5 the cut-off valve unit 12 is situated at the fuel tank 48 and the fuel is delivered to the pump 15 through part of the tube 26 surrounding the Bowden cable connected to the control knob 20.

Abstract: 1386472 Hydrostatic transmission control ROBERT BOSCH GmbH 21 April 1972 [22 April 1971] 18652/72 Addition to 1376829 Headings F2D and F2W [Also in Division GW3] In a hydrostatic transmission 11, 27 (Fig. 2) driving a hoist 28, the displacement of pump 11 is controlled by a servovalve 15 responsive to the output of an amplifier 13 receiving a control signal A and a displacement feedback signal from transducer 12. Signal A is transmitted through a limiter 17 receiving a demandlimiting signal B from amplifier 23 which receives a signal from amplifier 20 whenever a power output (P x Q, i.e. output pressure x flow rate) signal or computed at 18 exceeds set point signal C. The amplifier 23 also receives a signal E from unit 24 whenever the pump exceeds a given discharge pressure D during those periods when the pump is operating in either of the pumping quadrants of its P x Q characteristic. When the pump is operating in either of the motoring quadrants, i.e. when it is being driven by motor 27, unit E supplies instead a signal E<1> to a limiter 14 to limit the rate of pump adjustment. Unit 24 (Fig. 2) includes a selector 28 which admits the higher line pressure in the transmission to amplifier 33 which, when the pressure exceeds set point D, provides a signal on line F to spool 37 which transmits it to 39 or 40 according whether line 29 or 30 is at the higher pressure. Spool 38 transmits the signal F to 41 or 42 according to whether a signal on G from the displacement control loop is positive or negative. Signal F will thus appear on line 41 when the pump is pumping and on line 42 when the pump is motoring. Signals A, C, D may derive from electro-fluidic converters 16, 21, 25 respectively.

Abstract: 630,591. Reinforced concrete. MACERATA, S. July 15, 1947, No. 18803. Convention date, Aug. 12, 1946. [Class 20(iv)]  A method of constructing hollow prestressed concrete structures such as tanks, chimneys &c. comprises arranging a reinforcing wire to form, in plan, a polygonal figure, the direction of the wire being reversed at each corner thereof to form a loop projecting beyond the cross-section of the intended hollow structure, tensioning the wire at its free ends and possibly at one or more of said loops, casting or moulding the concrete to embed the straight sides of the figure, allowing the structure to harden and cutting off the projecting loops. Generally the wire will form one or more polygonal section spirals extending the whole or part of the height of the structure. A hollow structure as in Fig. 1 is constructed by erecting temporary scaffolding 16 at the corners of the intended struc-. ture and looping wires 2, 3 around sheaves 10 attached thereto, the free ends of the wires being secured to a stationary sheave 12 and a movable sheave 13. The wire is tensioned by a hydraulic jack 15 which forces sheaves 12 and 13 apart. Shuttering is then erected and concrete sprayed or cast to embed the straight parts of the wires within the walls 4. After hardening the loops 17 are cut off leaving the shell of the completed structure under compression. In forming cylindrical structures (Fig. 2 not shown) the wires lie tangentially within the walls.

Filed: 1937-07-07
Abstract: 502,171. Motor fuels. LEO CORPORATION. July 7, 1937, No. 18918. Convention date, July 13, 1936. [Class 91] Motor fuel contains a total of up to 0À085 per cent by weight of one or more #-diketone derivatives of the following metals, whereby no immediate anti-knock effect is produced but a deposit is gradually formed in the engine by continued use which deposit is effectively anti-knock. The metal may be cobalt, nickel, iron, manganese, copper, uranium, molybdenum, vanadium, zirconium, beryllium, platinum, palladium, thorium, chromium, aluminium, and cerium or other rare earth metal. The engine may first be run with fuel containing the higher percentages, e.g. 0À04-0À75 of dikotone derivative to build up the deposit, then on fuel containing only sufficient derivative e.g. 0À001-0À04 per cent to maintain the deposit and/or even for some. time on fuel containing no diketone derivative. Lead alkyl compounds, e.g. 0À1-5À0 cc. of lead tetraethyl per gallon, and non-corrosive organic sulphur compounds, e.g. 0À01-2À0 per cent of methyl, ethyl, or butyl sulphides or disulphides, carbon disulphide, or cyclic sulphur compounds may also be present. The preferred diketone compounds are the acetylacetonates, propionyl-acetonates, and formylacetonates; they may be halogenated. Fuels specified are gasolene, benzene, kerosene, fuel oils, alcohols, and mixtures thereof. For example, 0À04 per cent of a mixture of the propionyl-acetates of nickel, cobalt, and cerium with the acetyl-acetonates of thorium, zirconium, uranium, and chromium, with or without 2 cc. of tetraethyl lead or 7À5 cc. per callon of CS2, is used with gasolene. Specification 287,192, [Class 91], is referred to. The Specification as open to inspection under Sect. 91 describes the invention broadly as the use of fuel containing so small a concentration of organo-metallic compound that it has no effect on the combustion of the fuel but during continued operation of the engine forms therein a catalytic deposit improving the combustion. Reference is made to the use of proportions higher than 0À085 per cent ; and specified metallic compounds include amyl amine nickel chloride, manganese naphthenate, and palladium diethyl sulphide. This subject-matter does not appear in the Specification as accepted.
