Title: Distributor valve assembly
IPC: B60T15/04
Filed: 1955-06-16
Abstract: 770,835. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. June 16, 1955 [June 17, 1954], No. 17347/55. Class 103 (1). [Also in Group XXIX] In a driver's brake valve for a fluid pressure installation for a lorry or tractor trailer system having two independent fluid pressure circuits, two independent distributer valves operated by a single control member coupled to the distributer valves by means of a transmission, the ratio of which is controllable by the driver, permit the two fluid pressure circuits to be placed in communication with the atmosphere or with a source of fluid under pressure. In the embodiment illustrated, applied to a lorry or a tractor-trailer unit, a double body c of the distributer valve assembly comprises two cylinders 1, 1<SP>1</SP> forming, with the pistons 5, 5<SP>1</SP> two delayed reaction chambers 2, 2<SP>1</SP> connected by two small calibrated passages 32, 32<SP>1</SP> with chambers 3, 3<SP>1</SP> in communication with the circuits to be supplied. Chambers 4, 4<SP>1</SP> receive compressed air from reservoirs and flow of air from chambers 4, 41 to chambers 3, 31 is controlled by double distributer valve members 8, 8<SP>1</SP> and from chambers 3, 3<SP>1</SP> to atmosphere via tubes 6, 6<SP>1</SP> in pistons 5, 5<SP>1</SP>; a cover c<SP>1</SP> enclosing the control mechanism. In operation, when the driver depresses control rod 29, the floating lever 16 which, as a result of eccentricity of rod 29 relative to the mid-point of lever 16 and the more feeble resistance offered by the weaker right hand return spring 10<SP>1</SP> causes the right hand piston to move downwards before the other. This effect is not impeded at the commencement of the operation by the effect of biasing spring 20 since a lost-motion connection is provided between levers 16 and 17. Thus the right hand distributer valve is constantly in advance of that of the left whatever the relationship established for the final pressures of the two circuits. When the compression of the spring 13 is sufficient to bring about the opening of inlet valve on left hand distributer valve, compressed air will be supplied to the corresponding circuits and the pressures will develop in the two circuits depending upon (1) the compression of the two returning springs 10, 101; (2) the eccentricity of controlrod 29; and (3) the position of axle 22 of lever 17 which may be controllable by the driver by means of control member 25. By adjusting the position of axle 22, the driver can, at any time, distribute the braking to two axles on the same vehicle or to a tractor and trailer in accordance with the load it carries.

Title: Improvements in or relating to slabs or strips suitable for use as wall or floor panels
IPC: B32B27/00
Filed: 1964-04-28
Abstract: 1,056,147. Coated thermoplastic sheets. P. E. JOOS. April 28, 1964 No. 17632/64. Heading B2E. [Also in Divisions B5 and B6]. A method of manufacturing slabs or strips suitable for use as wall or floor panels comprises (a) successively depositing two or more gellable synthetic resin compositions on a support, each composition being gelled and cooled before deposition of the next succeeding composition. (b) heating the superposed layers to fuse adjacent layers, (c) cooling the fused layers and (d) stripping the cooled fused layers from the support, the first layer of gellable composition deposited being such that it is transparent when gelled and the final layer of gellable composition deposited being a composition comprising a blowing agent which is activatable during heating such that a foamed structure is finally formed. Advantageously, a coloured synthetic resin composition is deposited on the gelled first composition in any desired pattern e.g. by means of an engraved roller, to form an ornamental layer visible through the transparent outer layer. A plurality of different coloured compositions may also be used to form an ornamental layer of more than one colour. Preferably, a gallable third synthetic resin composition is applied to the ornamental layer to serve as a background thereto. Alternatively, the second composition deposited may be gelled, and part of it may be removed in accordance with a pattern so as to expose parts of the gelled first composition. A coloured third composition is then applied and serves as the ornamental layer. The coloured synthetic resin composition serving as the ornamental layer may be based on a vinyl chloride/vinyl acetate copolymer and it may be in the form of a gellable composition or a fusible powder. The first and final gellable compositions may comprise polyvinyl chloride. As shown, a gellable first synthetic resin composition is cast on to an endless conveyor belt 1 acting as a support, levelled by scraper 2, gelled inside kiln 3, and cooled by air at 4. The first layer is passed under engraved cylinder 5, which has recesses containing a second synthetic resin composition (Fig. 3, not shown). The second synthetic resin composition is deposited, dried, gelled and cooled. A third synthetic resin composition is applied by means of a scraper 8, and it is gelled at 9 and cooled at 10. A final synthetic resin composition is applied by means of scraper 11 and heated at 12. The four superposed layers are then heated in kiln 13 to effect fusion of adjacent layers, passed under roller 14 to obtain the desired thickness and cooled at 15. Reference numerals 19 denote chimneys. In an alternative method, a coloured second synthetic resin composition in a finely divided state may be sprayed over the gelled and cooled first layer. The slab or strip may be glued to any support, e.g. a floor or wall.

Patent GB-689878-A (GB)
Title: Improvements in and relating to the production of unsaturated carbonylic compounds
Filed: 1951-07-27
Abstract: Unsaturable aldehydes and ketones are separated from the products of oxidation of olefins of at least 3 carbon atoms by contacting with liquefied olefins suitable as feedstock to absorb carbonylic compounds and excess olefins which are recovered by fractionation. The process is made continuous by recycling olefins to the oxidation zone.  Water scrubbing may be used to remove other gaseous products. The oxidation may be effected as described in Specification 640,383 to yield acrolein, methacrolein, and methyl vinyl ketone from propene, isobutene and butene-1 or 2, preferably in the presence of added water vapour. On cooling, preferably by quenching with water, and compressing the reaction products, a liquid aqueous phase containing any formaldehyde separates.  Further cooling and compression may separate liquefied hydrocarbon.  The gaseous phase is then subjected to the absorption.  Alternatively, the reaction products may be extracted with water and olefin to give a liquid olefin phase containing the unsaturated, and an aqueous phase the saturated carbonylic products, e.g. acetone, acetaldehyde, propionaldehyde, and isobutyraldehyde.  In examples, propene and isobutene are oxidized with oxygen or air in presence of cuprous oxide, the products being treated by separating a liquid olefin phase and contacting the residual gas phase with liquefied olefin or by separating both liquid aqueous and olefin phases, when steam is added during the oxidation, and contacting the residual gas phase with olefin.  The extraction of carbonylic-containing solutions with both water and liquid olefin, introduced at opposite ends of an extraction column, is also illustrated. Specification 675,544 also is referred to.

Abstract: 816,933. Magnetic recording and reproducing apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 5, 1957 [June 8, 1956], No. 17893/57. Class 40 (2). In a combination of a superheterodyne radio receiver and a magnetic record head, the record signals received by the head from the record are modulated by an alternating current from the superheterodyne local oscillator which is tuned to the same frequency as the intermediate frequency circuit associated with the output from the mixing stage, the resulting modulated signal being fed to a further input of the mixing stage. Fig. 1 shows an embodiment in which the full line positions of the switches indicate block diagrammatically a normal superheterodyne radio set. When switched to the dotted positions of switches S 1  and S 3'  the local oscillator G supplies a carrier frequency to the head via coils a and b on parallel limbs 4 and 5 of the core 2. The coils a and b are wound in such directions as to produce fluxes in aiding relation with respect to each other but in opposing direction around the core, and serve to modulate the audio signal induced in coil c, the output voltage from which is applied to a further input of the mixing stage M of the heterodyne circuit. Fig. 2 shows an alternative design of head in which the ferromagnetic circuit 6 has a tubular portion 7 of a material having a non-linear magnetization curve including a coil 8 receiving the carrier alternating current.
