Patent GB-2121120-A (GB)
Title: Rolling bearings
Inventor: WREN FREDERICK JAMES
IPC: F16C33/62
Filed: 1983-04-20
Abstract: The invention relates to rolling bearings, but more specifically to a tapered roller bearing of the type used in applications where, in service, the inner and outer race members rotate together without relative movement for much of the time. Fretting corrosion known as "false brinelling" which can occur in these circumstances is prevented by modifying the surface coefficient of friction of one or more of the inner and outer raceways and the rollers in such a way as to ensure that creep occurs while in service. The surface treatment takes the form of a phosphate coating applied by a chemical treatment process to produce a layer of manganese phosphate or zinc phosphate on the surface of the component concerned. Advantageously a small amount of misalignment between the inner and outer race members may be deliberately introduced to enhance the effect of the surface treatment. <IMAGE>

Title: Article coating process
Inventor: JOHNSON RAYMOND EDWARD
IPC: B05D3/02
Filed: 1983-07-25
Abstract: In a method of coating an elongate article such as a pipe 6, an article is passed through a suspended mass of heat-sensitive coating material and the article is subjected to localised heating by a heating device, e.g. induction coil 9, at a location in which the article is in contact with the material, while relative movement between the article and heating device is effected. The rate of movement and heat applied are controlled so that the material is caused to coat the heated portion of the article upon contact therewith. The pipe or other article may be moved relative to an induction coil or the induction coil may be moved relative to the pipe or other article. <IMAGE>

Title: Forming plastics sheet with lines of weakness, cable joint casing construction, plastics sheet former construction
Inventor: GILBERT MICHAEL
IPC: B29C51/32
Filed: 1983-10-11
Abstract: In a method of making a flanged moulding of plastics sheet material 3, the sheet material is vacuum-drawn onto a former means 10, in such a way that the desired periphery of the flange corresponds to a line of weakness which is provided by a sharp bend 16, in the plastics of material of at least 90 DEG  and in which the desired moulding is subsequently broken out of the remainder of the sheet along the line of weakness. A flanged moulded cable joint casing 1, comprises a pair of flanged members 3, 4, of moulded plastics material secured with their flanges in face-to-face contact, wherein the flanges are sloping towards each other so that when unstressed they contact each other at the outside.   In a former assembly for moulding plastics material sheet into a flanged part of a cable joint casing, the former (not shown) is secured to or integral with a plinth 10, providing a surface for forming the flange. <IMAGE>

Title: Computer Graphics System
Inventor: STOCK RODNEY DENNIS
IPC: G09G5/02
Filed: 1984-04-13
Abstract: In a computer graphics system, video data is loaded into an addressable frame store (50) and is read therefrom by video output processor (42) to form a raster display on colour monitor (38). The frame store (50) is expansible, one 8-bit byte per pixel providing monochrome display or addressing a colour map memory providing 256 shade/intensity levels. Two bytes per pixel provides one byte to define the luminance of each pixel and a second to define the I, Q colour vectors of pairs of pixels, the colour resolution therefore being half that of the intensity. Three bytes per pixel allows separate definition of the intensity of each primary colour red, green, blue. A further frame store holding one bit per pixel may be provided to enforce overlay by a selected colour where required. Stored parameters govern the mode of operation of the system. <IMAGE>

Patent GB-2168770-A (GB)
Title: A system for automatic wear compensation inserted in a hydraulic unit actuating a drum brake
Inventor: BELLOMO DR MATTEO
IPC: F16D65/22
Filed: 1985-12-21
Abstract: A pair of opposing pistons 4, 8, which are connected to the shoes (not shown) to apply braking pressure thereto, are slidingly accommodated in a fixed cylinder 1 connected to a hydraulic braking circuit. A spacer member 17, 18 is connected between the pistons 4, 8, and when the pistons move apart by a distance greater than the spacing between stop rung 21 and spigot 16, due to wear of the linings of the brake shoes, the spacer member will be rotated by the screw threaded engagement between the piston 8 and element 18. If that distance is sufficiently large a spring biassed pawl will move over, and, on brake release, will engage the stop face of, the next one of sawteeth 14, whereas if that distance is not sufficiently large the pawl will ride up the face of the next sawtooth but will return to engage the stop face of the previous tooth on brake release. The compensation mechanism is restored to its original position when the worn linings are replaced by causing one of the two pistons of the hydraulic actuation unit to rotate with respect to the other. <IMAGE>

Title: Process for the enrichment with ???6 fatty acids of a mixture of fatty acids
Inventor: TRAITLER HELMUT
IPC: C07C51/487
Filed: 1986-01-31
Abstract: For the selective enrichment with fatty acids, of which the first double bond is in the 6 position, of a starting material containing fatty acids of which the first double bond is in the 6 or 9 position, the starting material is treated with a saturated solution of urea in methanol with predetermined ratios of fatty acids to urea so as to separate the fatty acids other than the ???6 polyunsaturated in the form of an insoluble inclusion complex. The enriched fractions obtained may be treated by high-performance liquid chromatography to isolate the substantially pure ???-linolenic acid. The enriched fractions, optionally recombined with the glycerol, may be used in medicaments and in nutritive compositions or may serve as starting product in the synthesis of dihomo-???-linolenic acid. <IMAGE>

Title: Releasably mounted potters wheel bat and tumbling mill
Inventor: KIRK TERRY DAVID
IPC: B28B1/02
Filed: 1986-08-22
Abstract: A disc shaped potters bat cam (8) is releasably clamped to a disc shaped bat holder (1) which is securable to the potters wheel. The releasable clamping is effected between opposed tapered surfaces, of three jaws (2) spaced around the holder periphery, and of the cam periphery which is also "egg shaped" to enable the cam and holder to be manually brought into contact, and then clamped upon relative rotation. The cam has manual lifting recesses (10), and a larger bat disc (11) may be secured to the bat cam. The cam or disc may support a jigging cutter for cutting either a plaster plate mould, or a clay plate upon the mould, or may support a tumbling frame (40), for tumbling rotation of a milling or stone polishing cylinder (46), upon relative rotation between the disc and wheels (42) of the frame. Axial movement of container 46 may be prevented by two vertical end plates, one between rollers 44 and 45 and the other at the other end of rollers 44. <IMAGE>

Title: Apparatus for filling and sealing open bags
Inventor: COMBRINK ALOIS
IPC: B65B7/06
Filed: 1987-10-08
Abstract: In apparatus for filling and sealing double-seamed bottom bags having an internal coating there are in addition to impressing elements 10, 11 pivotable about horizontal axes (8, 9), pressing strips (16, 17) which move in a vertically downwards direction after closure of the impressing elements to press the bagwalls against the contents to express air from the bag. Instead of the pressing strips 16, 17, a suction nozzle 20 (Fig. 4) can be provided to extract the air, said nozzle being vertically displaced into the bag, passing between the impressing element 10, 11. So that the top edge of the bag is maintained at the same height, a bag conveyor 2 is vertically movable. By reason of the additional pressing strips 16, 17 or by reason of the suction nozzle, the air present inside the bag is extracted despite the stiffness of the bags. Since no air cushions are able to form, the strain on the interior sealing seam is relieved so that it can reliably be assumed that the bags are sealed in absolutely airtight fashion. <IMAGE>
