Abstract: 994,095. Coating articles with liquids. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 13, 1964 [April 22, 1963], No. 15838/63. Heading B2B. Apparatus for coating polyolefinic homopolymer and copolymer articles with lacquer or paint comprises a tank 1 adapted to contain in a lower portion thereof a body of volatile liquid 3, a vertical partition 6 dipping below the liquid level and dividing a portion of the tank which is above the liquid level into two upper compartments A and B, means for heating said liquid, means for condensing vapour from the liquid in compartment A to prevent the accumulation of vapour therein, means for condensing vapour in compartment B spaced away from the liquid level so as to allow the establishment of a zone of concentrated vapour between the liquid level and the condensing means, means for heating the zone of concentrated vapour, and means for conveying articles downwards into the tank through the vapour-free space on one side of the partition, into the liquid, across the tank, up through the heated zone of concentrated vapour on the opposite side of the partition and out of the tank. In the arrangement shown the heating means consists of water jacket 4 with electric heater 5 therein. Compartment A is provided with a water-cooled condensing surface 7 having its lower limit close to the surface of liquid 3 so as to prevent build up of vapour in this compartment, whilst compartment B has a water-cooled condensing surface 8 spaced away from the surface of liquid 3 so that it prevents escape of vapour but allows the establishment of vapour zone 9. As an extra safeguard against escape of vapour openings 11 are provided at the rim of the tank and are connected via pipe 10 to an extractor fan and thence to a recovery system. The articles may be rotated whilst in the vapour zone to assist draining and evening of the coating on the articles. Coating compositions for application to polyolefinic surfaces are formed of resins soluble in trichloroethylene or perchloroethylene, e.g. chlorinated polymers and alkyd/urea resins. Particularly suitable chlorinated polymers are chlorinated rubber, chlorinated polyisoprene and the soluble varieties of chlorinated polypropylene, chlorinated polyethylene, and chlorinated polyvinyl chloride. Other resins that are soluble in chlorinated hydrocarbon solvent employed, for instance, acrylic resins, may be mixed with these chlorinated polymers, and the compositions will usually include plasticizers or extenders such as the chlorinated paraffinic oils and waxes and the chlorinated diphenyls. Such mixtures may be employed as clear lacquers or they may contain opacifiers, pigments, dyestuffs and metallizing powders.

Inventor: DALFSEN JAN VAN
IPC: A21D2/16
Filed: 1962-04-30
Abstract: A confectionery paste (see Division A2) comprises a fat which contains a major proportion of a palm oil fraction obtained, from palm oil, by the substantial removal of the tri-saturated glycerides, with or without subsequent partial hydrogenation of the whole or part of said palm oil fraction.  The tri-saturated glycerides may be removed by fractional crystallization from an organic solvent, such as acetone.  The palm oil fraction may be the residual fraction, namely palmolein, remaining after 15 to 45%, by weight, of the palm oil, in the form of an upper melting fraction, has been removed.  One quarter of said palm oil fraction (palmolein) may be partially hydrogenated, e.g. to attain a slip melting point between 30 DEG  and 40 DEG  C., and an iodine value between 56 and 40, and then mixed with the remaining three-quarters to yield a suitable fat.  The fat may be plasticized by being passed through a cooled, scraped-surfaced, tubular heat-exchanger, or by being passed over chilled drums and then scraped off them.

Title: Improvements relating to starting mechanism for internal combustion engines
IPC: F02N15/02
Filed: 1922-06-14
Abstract: 203,787. Horstmann, S. A., and Rooke, J. W. June 14, 1922. Turning-gear.-In a starting-device for internal-combustion engines, a worm 3 driven by an electric motor 1 is in constant mesh' with a worm wheel 19 connected to the engine shaft 5 by clutch members such. as pawls 10 disengaged by centrifugal action when the engine attains normal speed. A ratchet wheel 6 secured to the worm wheel is engaged by the pawls 10, which are pivoted upon a disc 9 mounted on the engine shaft and are restricted in their movement bv pins 12 entering circular recesses 13 in the disc 9. One of the pawls is normally held by gravity in engagement, with the ratchet wheel, until they are thrown outwards by the rotation of the engine shaft. The worm 3 is slidable on a hexagonal or splined sleeve 2 connected to a coaxial spindle 21 by a cotter 22 fixed in the spindle and entering a slot in the sleeve 2, the spindle 21 being connected to the spindle 25 of the starting-motor by a key 26 and pin 27. The sleeve 2 runs in a ball bearing 14, and a spring 15 is interposed between a thrust bearing 23 and a collar 20 on the spindle 21, to oppose longitudinal movement of the worm on its spindle due to the resistance of the engine to turning. In a modification, the spring 15 is replaced by a spring between the worm and the ball bearing. The Provisional Specification comprises also a form in which the worm is normally out of engagement with the worm wheel and is brought into engagement when the motor is rotated, by means of a pawl in engagement with the threads of the worm or by centrifugal, magnetic or other means.

Title: Improvements in or relating to transmission and/or reproduction of views, scenes or i mages by wires or wirelessly
IPC: H04N5/66
Filed: 1925-09-01
Abstract: 267,378. Baird, J. L. Sept. 1, 1925. Television.-To obtain certain half tone or colour effects the signal impulses produced at the transmitting station are amplified to widely different degrees prior to their utilization at the receiving station. Fig. 1 shows an arrangement employing a single light-sensitive cell 1 in the transmitter and a single light source 6 in the reproducer. The received impulses are delivered to the source 6 through thermionic or other amplifiers 3, 4 of low and high ratio respectively, arranged in parallel, and each provided with a series regulating resistance 8, 9. The amplifier 4 is so biased as to be inoperative for weak signals, whereas both amplifiers may be effective for strong signals. The intensity of the source 6 thus corresponds to half tone or full tone according as weak or strong impulses are received. In another arrangement, Fig. 2, the output currents from the amplifiers 3, 4 are applied to separate light sources 10, 11 respectively of different intensities or differently shaded. The amplifier 3 may be rendered inoperative when the amplifier 4 is operating by providing a light-sensitive cell 13, subjected to the light from the source 11, so arranged that the photo-electric current produces a biasing action on the amplifier 3 or opposes the current through the amplifier, e.g. the cell May constitute coupling resistance between amplifying stages. To obtain colour effects the source 6, Fig. 1, may be a neon lamp giving a red glow discharge at e.g. 200 to 250 volts and a blue arc discharge at e.g. 800 to 850 volts. A neon lamp with mercury electrodes or having, mixed with the neon, mercury vapour or helium or other gas giving a bluish spectrum is suitable. Two light-sensitive cells may in this case be used at the transmitting station, one, covered by an orange-red screen, being in circuit with the amplifier 3, and the other, covered by a green blue screen, being in circuit with the amplifier 4, and if a light-sensitive cell is used as described above for rendering the amplifier 3 inoperative, a green blue screen is placed between the source 6 and this cell. Alternatively two cells responding differently to lights of different colours may be used at the transmitting station. The sources 10, 11, Fig. 2, may also differ in colour instead of differing in intensity.

Title: Improvements in fluid flow control valves
IPC: B64C11/30
Filed: 1942-11-24
Abstract: 563,212. Fluid-pressure servomotor control systems. DE HAVILLAND AIRCRAFT CO., Ltd., and DOVE, E. B. Nov. 24, 1942, No. 16662. [Class 135] A hydraulic control mechanism for variable pitch airscrews controlled by an enginedriven governor to maintain the engine speed constant includes a manually-actuated valve adapted in one position to connect the governor unit to the pitch servo-control piston and the throttle power piston to exhaust, in a second position to connect both power pistons to exhaust and in a third position to connect the governor unit to the throttle power piston and the motive fluid supply directly to the pitch power piston. The pitch servo-piston is provided with a follow-up sleeve and controls the piston of the blades either by means of a hydraulic jack or by means of clutches through which pitch changing gearing is operatively connected to a powerdriven shaft which is constantly rotating or otherwise. The valve member 20 has two flats 24, 26 and a through passage 28 leading from the flat 24 to one of the lands of the piston. In the position shown, a pipe 18 leading to the governor unit is connected to a pipe leading to the servo-control piston while a pipe 14 leading to the throttle jack is coupled to the exhaust pipe 32. By moving the valve member downwards, pipes 16 and 18 are closed and the pipe 12 leading to the servo-control piston and the pipe 14 are connected to the exhaust pipe. This allows a spring associated with the servocontrol piston to move it towards the feathering position. If the valve is moved upwards, pipes 14, 18 are connected to put the throttle jack under the control of the governor unit and to connect the pipe 12 to a pipe 16 supplying motive fluid so supplying pressure fluid to the servo-control piston in the direction to cause the pitch of the blades to become progressively finer and finally assume a negative pitch. According to the Provisional Specification, the valve may be used for other purposes. Specification 581,326 is referred to.

[Class 103 (vi).] The railway &c. vehicle undercarriage described in the parent Specification is modified in that the cylinder e within which the king-bolt a depends is connected to the bogie or axle through the medium of a ball and socket,f, g or other universal joint, and its displacement in the longitudinal and transverse directions is elastically opposed by means which tend to restore it to a vertical or central position. In the construction shown, the ball and socket joint is arranged at the lower end of the cylinder e, the socket g being rigidly connected to longitudinal members h of the bogie frame, while the elastic means comprise rubber pads k, l disposed on four sides of the cylinder near its upper end. The rubber pads are adapted to be compressed between metal plates k<1>, k<2>, 11, l<2>, and additional resistance to movement of the cylinder is provided by friction surfaces i, j on the cylinder coacting with the inner plates k<1>, l<1>. The ball c at the lower end of the king- bolt a is connected to a piston d and, since the distance between the centres c', o of the balls c, f diminishes as the vehicle load increases, the effective leverage of the pads k, l increases. By connecting the socket g directly to the members h, the usual bogie bolster and suspension means therefor may be dispensed with. In place of separate pads k, l a single rubber annulus may be employed, or springs or other equivalent means may be substituted for the rubber. Bellow-like casings p. q are provided to maintain fluid-tightness.
