Title: Improvements in or relating to flexible bearings
IPC: B60G11/12
Filed: 1944-09-08
Abstract: 581,541. Resilient mountings. THIRY, L. F. Sept. 8, 1944, No. 17180. Convention date, Aug. 12, 1943. [Class 108 (iii)] In a resilient mounting consisting of inner and outer members connected together by a resilient member placed under axial compression by thrust members at the outer ends of the bearing, the resilient member is formed of a pair of cylindrical bushings each having at one end a number of circumferentially spaced radial projections. In Fig. 1, the resilient member which is mounted between the inner and outer members 10, 11 is made up of two bushings 15, Fig. 4, provided with radial projections 17 to locate the bushings in the outer member 11. The use of radial projections instead of flanges reduces the pressure required to distort the ends of the resilient member when it is placed under axial compression with a consequent increase in the pressure forcing the bushings together at the centre of the mounting. To prevent binding of the bushings on the outer member 11, the whole or part 18, Fig. 4 of the outer surface may be treated so that the coefficient of friction between the metal and rubber is reduced. A number of ways of doing this are described, and among others, the use of a thin film of methocrylate resin or the use of a varnish or drying oil such as tongue oil, perilla oil are mentioned.

Abstract: 745,638. Proofing permeable materials. CIBA Ltd. July 9, 1952 [July 10, 1951; June 4, 1952], No. 17361/52. Class 140. In a process for rendering cellulosic fibrous materials having a low swelling capacity waterresistant and resistant to attack by microorganisms by impregnation with an aqueous solution or emulsion of a hardenable amino plast with or without a curing accelerator, the aminoplast is converted to the water-insoluble state without completely removing the water absorbed from the impregnating bath, the quantity of aminoplast deposited on the fibrous material being from about 3 to 10 per cent of the weight of the fibrous material. The impregnated material may be stored at room temperature or at a temperature of 80‹ C., preferably in a closed vessel or in a drying chamber through which is passed air of predetermined relative humidity. After the resin is fixed the material may be rinsed and dried. Suitable cellulosic materials include natural celluloses such as cotton and bast, and they may be treated as loose material (yarns, sliver) or as finished goods. Other protective agents such as tanning agents, fungicides or bactericides may also be added. In an example cotton twist suitable for fish netting is impregnated with a solution of a 1 : 3 molar melamine/formaldehyde condensation product, formic acid and a non-ionic wetting agent, hydroextracted and stored in a closed vessel for 1-3 days, washed and dried.

Abstract: 731,594. Feeding sheets &c. HALL TELEPHONE ACCESSORIES, Ltd. July 23, 1952 [July 24, 1951], No. 17465/51. Class 100 (1). Flat articles, such as postal letters, are separated from a pile by a suction separator 5 which first lifts the top letter and then moves it transversely so that it rides up a curved and inclined guide plate 6 to be gripped between endless belts 7 and rollers 8. The latter is registered by abutting the plate 6 before it is moved up the surface thereof. It is fed upwardly by the belts and rollers until the trailing edge of the latter engages teeth in rotating serrated wheels 9 which bring the letter into an approximately vertical plane, and it then drops between front and rear guides 11, 12 on to a gate 10 which is opened intermittently to allow letters to fall on to a conveyer belt 13. To prevent more than one letter being removed from the pile by the sucker 5, adjustable stops 1 are arranged to engage and bend each letter as it is lifted from the pile by the sucker. The belts 7 are arranged to project through slots in the guide plate 6, and are depressed by resiliently mounted rollers 8. These rollers are moved away from the belts and plate 6 in accordance with the thickness or stiffness of the letters, and this movement may be arranged, in known manner, to operate a switch to allow for the removal or interception of all letters exceeding prescribed limits of thickness and stiffness. The gate 10 is solenoid-operated and its movements are co-ordinated in known manner with the movements of the sucker 5.

Title: Improvements in electric regulators of the carbon pile type
IPC: H01C10/10
Filed: 1942-12-16
Abstract: 562,191. Compression resistances. STONE & CO., Ltd., J., and CROTCH, W. A. Dec. 16, 1942, No. 17874. [Class 37] In a carbon pile regulator wherein a friction tight pivotal joint is provided between the presser means engaging the pile or piles and the pressure applying system which is operative for compressing the pile or piles, this joint is arranged so that upon transmission of maximum compression forces the frictional tightness is eased or substantially removed but is restored as the compression forces are reduced. The carbon pile of a single-pile regulator consists of superposed carbon rings a with a collector ring b at the top-surmounted by a presser ring c. This is formed with a diametral cross-bar c<1> to which is jointed an axial rod d connected with the magnet-operated system of the regulator, the lower end of the rod d is forked and between the prongs of the fork a small block e is fixed by rivets f. The upper surface of this block is spherical and engages a conical seating on the cross-bar c<1>. Downwardly projecting pins g are fixed to the cross-bar c<1> and carry springs j which exert upward pressure against a yoke h slidably mounted on the pins. This yoke is formed with a projection h<1> which engages the flat lower surface of the block e and forms a pivot. Normally the rod d is depressed by a loading spring and applies maximum compression to the pile by depressing the yoke h and thereby further compressing the springs j, so that extra pressure is applied to the presser ring c. At the same time the spherical surface of the block e is loosened from engagement with the conical seating surface and the presser ring c is free to adjust itself so as to apply pressure equally around the pile rings. When the rod d is lifted by the electromagnet of the regulator to increase the resistance of the pile, the spherical surface of the block e is forced against its seat by the springs j so that the ring c is held in its adjusted position. The springs are preferably initially adjusted so that their combined force is about equal to the maximum compression force applied to the rod d. Modifications are described having two and three piles, in the former case the spherical surface of the block e being replaced by a cylindrical surface.

Abstract: 949,330. Cathode-ray tubes. GENERAL ELECTRIC CO. May 17, 1961 [May 19, 1960], No. 17960/61. Drawings to Specification. Heading H1D. A target for use in a television camera tube comprises a composite storage membrane supported solely at its periphery and having a thickness of between 500 and 1000 A, and consisting of a first layer of a homogeneous polycrystalline semi - conducting oxide having straight-through electron conductivity and high lateral resistance and a second layer of a material having high lateral resistance fused to the first layer. The first layer is preferably of magnesium oxide and the second layer is of aluminium oxide or a noble metal sub-divided into a myriad of discrete islets and constituting 0.5 to 10% of the overall thickness of the membrane which may be 750 A. The target may be manufactured by forming a vaporizable film of nitrocellulose across an annular support, evaporating a layer of aluminium or a noble metal such as gold on to this film and coating this layer with magnesium. Subsequent heating of the target in an oxidizing atmosphere vaporizes the nitrocellulose film, oxidizes the magnesium and either oxidizes the aluminium or coagulates the noble metal. The presence of the second layer causes the membrane to be extremely taut and the magnesium oxide to be fine grained. Also the second layer has a lower secondary sensitivity which is desirable for the electron gun side of the target.
