Abstract: 640,955. Pulleys. WATT, T. Nov. 25. 1947, No. 31225. [Class 80(i)] [Also in Groups XXVI, XXX and XXXIV] A bearing assembly for a pulley or the like comprises a ball or roller bearing having its outer race housed in an annular recess in a split resilient bushing the parts of which are clamped together by rigid clamping members, the bushing preventing direct contact of the clamping members, A rope guiding roller, Fig. 1, comprises two hollow frustro-conical members 1 having flanges 2 between which the two bushing parts 3 are clamped by means of bolts 4. The outer race 8 of the ball bearing is disposed in an annular recess in the bushings 3, and the inner race is located on a shaft 6 by circlips 9. A lubricant reservoir 11 is formed in the hollow shaft 6 and communicates with the bearing through radial ducts 12. Sealing means are provided on each side of the bearing. In a modification. Fig. 2, felt packing 15 is disposed beween bushing parts 3a to form a radial lubricant passage for the lubrication of the rope. Lubricant reservoirs 18 are rotatably mounted on the shaft on each side of the bearings and supply lubricant to the reservoirs 11a in the shaft through holes 23. The reservoirs 18 are divided into plurality of compartments by radial walls. The adjacent faces of the members 3a may be corrugated to prevent excessive outward flow of lubricant. In a conveyer belt roller, Fig. 5, a V-shaped protrusion 34 on the roller casing 35 is frictionally engaged by a V-shaped surface 33 formed by the bushings 30. In a wide pulley, Fig. 7, wherein a bearing is provided at each end, resilient bushings 38 are clamped between walls 41 and end covers 39 screwed on the ends of the cylinders. In an arrangement of conveyer belt rollers, Fig. 10, the rollers are mounted on stub axles 61 which are mounted on a pedestal 62. The end of the bearing chamber is closed by a cover plate 64 for retaining lubricant. In the arrangement shown in Fig. 12, locating elements 75 are disposed in the ends of shafts 65. The elements 75, Fig. 14, each comprise a portion 76 having a lubricant passage containing a spring-pressed ball valve 79 and a flanged head 77 which fits in a support 81. Annular packing 87 is provided. Specifications 640,917 and 640,954, [both in Group XXXIV], are referred to.

Abstract: 1,269,823. Film fibrillation. MONSANTO CHEMICALS Ltd. 5 May, 1970 [23 June, 1969], No. 31655/69. Heading B5B. Fibrous material is produced by passing a film or sheet of thermoplastic material which has been longitudinally orientated through the nip between a pair of rotating rolls, each roll having a series of circumferential ribs, the ribs of one roll intermeshing with those of the other so as to cause transverse stretching resulting in fibrillation. The film or sheet may consist of foamed thermoplastic material. The ribs may be thin plate-like projections which are integral with the rolls. The ribs may have a depth of from # inch to 1 inch and a thickness of from 1/16 to # inch. They may be 3/16 to # inch apart and their outer surfaces may be slightly roughened. The diameter of the rolls may be from 2 to 8 inches and they may be driven at a peripheral speed of from 10 to 1000 feet per minute. The film or sheet preferably comprises. a polymer or copolymer of an ethylenically unsaturated monomer, particularly high density polyethylene. The fibrillated web may be subjected to the. action of a turbulent stream of air to cause further fibrillation. The film or sheet is preferably stretched transversely before being passed through the nip of the' rolls, for example by passing it across a surface such as a spreader bar curved in a direction transverse to the direction of travel of the film or sheet and thereafter over an associated plain idler roller to flatten out the film or sheet before it is passed through the nip of the ribbed rolls.

Abstract: 857,885. Capacitors. PLESSEY CO. Ltd. Oct. 3, 1958 [Oct. 7, 1957], No. 31657/58. Class 37 In an arrangement for manufacturing capacitors by depositing on a support 1, Fig. 1, of ceramic or glass superposed layers 4-8 formed alternatively of an electrically conductive material and of a dielectric material. Supports 1 are mounted on a spindle 19 in lugs 17, 18 projecting from radial arms 15, and the arms are rotated about a central spindle 16 so that the supports pass over apertures 12, 121, 12<SP>11</SP> above sources 14 of vapourised metal and dielectric so that the layers are alternately applied. Aluminium, beryllium and zinc are mentioned as electrodes and a mixture of oxides and metallic salts such as barium titanate or lacquers of high homogeneity, as the dielectric. The spindles 19 are rotated during the rotation of arms 15 about a central spindle 16 by friction rollers 20. The depositions may be controlled by varying the speed of rotation, and measurements of capacity and dielectric strength may be made over rubbing contacts 21, 22. The arrangement shown which is suitable for a two electrode single layer capacitor may be modified by the addition of further screened sources to provide a multiplicity of layers for each electrode. The apertures are staggered radially to form electrodes insulated from one another but in contact with the metallised ends 2, 3, of the base, and their edges are shaped to produce an even deposit.

Abstract: 745,602. Door handles. LILLY & SONS, Ltd., B. Aug. 31, 1954 [Nov. 20, 1953], No. 32200/53. Class 44. Relates to a lever type door handle fitting of the kind comprising a lever handle member 5 carried by a shank 6 which is rotatably mounted in a bearing boss or aperture of an attachment or back-plate 1 adapted to be secured to the face of a door, the shank having in its rear end a square or other non-circular hole 9 adapted to receive a latch operating spindle and being acted upon by a spring 15 which normally retains the door handle member in a horizontal position as determined by stop means.

Title: Improvements in or relating to circuit arrangements employing charge storage tubes
Inventor: MANLEY BRIAN WILLIAM
IPC: H01J31/60
Filed: 1961-09-07
Abstract: 994,066. Cathode-ray storage tubes. MULLARD Ltd. June 28, 1962 [Sept. 7, 1961], No. 32248/61. Heading H1D. A charge storage tube comprises an electron gun, a target having an uninterrupted secondary emissive storage layer T on a conductive backing S, and an electron collector adjacent the target. Writing is effected by deflecting the electron beam in a focused condition over a first path, the form of which is representative of input signals. Reading is effected by scanning the beam, in a constant current focused condition, over a second path of raster form which intersects the first path at a plurality of spaced points, and with potentials such that the secondary emission ratio is greater than one, to obtain an output signal from target backing S, or from the electron collector. The storage layer T may be of mica, writing being effected with a beam energy producing a secondary emission ratio greater than one, or layer T may be of B.I.C. material, e.g. zinc sulphide or magnesium fluoride. As shown in Fig. 5B, the target T is initially stabilized at 0V, and a written oscillograph trace W is charged positively to +5V. After one or more initial reading scans R, all elements in the path of the reading beam are charged to a maximum of say 10V positive with respect to adjacent target elements. Repeated read-outs are possible because during each reading scan, and before the next, secondary electrons are redistributed to some extent, but only go to the most positive target elements, so that the points PI-P4 of intersection of the writing and reading paths drift negatively to say 14V, and so give rise to an output signal during the next read scan when they are again charged to 15V. To effect erasure and to stabilize the target at 0V, switches Sa, Sb, Sc, Fig. 6, are moved to position 2, to produce a beam energy below the first cross-over. The electron collector may be a mesh 3 mm. from the target or may be a peripheral ring. In an alternative method of operation, each reading scan may be followed by a restabilizing scan or flood as described in Specification 994,065.
