Title: Bearing assembly
IPC: D21F1/00
Filed: 1974-09-13
Abstract: 1503150 Bearings; rollers JOHN D HOTCHKISS Ltd 15 Sept 1975 [13 Sept 1974] 40017/74 Headings F2A and F2U [Also in Division D2] A bearing assembly comprises a cylindrical sleeve 6 attached to a roll 7 and having first and second end portions spaced by a midportion, the internal diameter of the first, inner end portion being smaller than the internal diameter of the second, outer end portion, a cylindrical housing 4 received within the sleeve and having end portions which are a tight fit in the corresponding end portions of the sleeve, a bearing 8, 8<SP>1</SP> fitted within each of the first and second end portions of the housing, and a stub shaft 15 received in said bearings and extending beyond the bearing 8<SP>1</SP>, the arrangement being such that the housing, containing the bearings and the stub shaft, can be extracted by hand after axially displacing the housing from the sleeve so that the first and second end portions thereof are no longer in contact. The axial displacement is effected by removing screws 5 together with a cover 3 and inserting the screws into tapped holes 19, thereby forcing the housing and sleeve apart by the required amount. The inner end of the assembly is enclosed by a cover 3<SP>1</SP> provided with a pressure release valve 18. The stub shaft 15 is mounted in a bracket 21. Where the stub shaft and roll are each hollow, a tube may be coaxially located in the stub shaft to supply heated air or steam to the interior of the roll. The roll has a perforated surface to allow the heated air or steam to escape. Circular disc-shape baffles are attached to the inner ends of the tube so as to direct the heated air or steam to different sections of the roll. The tube is axially slidable, either manually or automatically in accordance with a moisture profile measured across a web carried by the roll.

Abstract: 943,461. Vehicle independent suspensions. FORD MOTOR CO. Ltd. Oct. 23, 1962 [Dec. 4, 1961], No. 40031/62. Heading B7D. In a vehicle with spring suspension permitting " recession " of wheel 30, one of the fore and aft pivotal connections of a suspension arm to the spring vehicle parts includes a metal spring 42. The suspension arm, Fig. 1, comprises a transverse member 20 pivoted at 22 to the frame on a rubber bush and an oblique rod 36 connected to member 20 by pin 38 and to frame 10 by L-shaped metal spring 42. The rod 36 passes through a hole in the lower limb of spring 42 (Fig. 3) axial movement of the rod being resisted by a pair of annular rubber members 46 mounted adjustably on the rod. When the wheel is subjected to longitudinal shock loads, spring 42 flexes and member 20 rotates the rubber bush at 22 allowing the wheel 30 to move backwards. In a second embodiment (Fig. 5), the front limb 78 of a suspension wishbone 60 is connected to frame 10 by L-shaped spring 66, rubber bush 72 and pivot pin 74. The other connection between wishbone 60 and frame 10 is a rubber bush and pin coaxial with pin 74.

Abstract: 931,499. Reducing iron ores. ESSO RESEARCH & ENGINEERING CO. Nov. 21, 1961, No. 41599/61. Class 72. A process for the direct reduction of iron oxides in a fluidized bed comprises reducing higher oxides to FeO in an initial stage and reducing FeO to Fe in a final stage, an intermediate exhaust gas containing CO and H 2  and small amounts of C0 2  and H 2 O being removed from the final stage, a minor amount of the intermediate gas being passed to the initial stage and a major proportion being regenerated, added to the gas from a generator zone and fed to the final stage reducing zone. As shown, finelydivided iron oxides in a fluidized bed in vessel 2 are reduced to FeO and removed by a tube 7 for transfer to a final reducing vessel 9 through a line 8. Hot reducing gas is fed to the vessel 9 from a gas generator 10 and a minor part of the exhaust gas is used to reduce the higher oxides in vessel 2. The major part of the exhaust gas is recycled through a line 18 to the gas generator 10. The exhaust gas from vessel 2 may be burned to supply heat to the generator and the products of combustion used to dry or preheat the ore. Any sulphur in the recycled gas may be removed by passing over iron.

Abstract: 1,152,534. Preparation of alkyl-substituted chlorophosphines. KNAPSACK A.G. 12 Sept., 1967 [17 Sept., 1966], No. 41601/67. Heading C2C. Alkyl-substituted chlorophosphines of general formula R n P(Cl) 3-n , in which R is a C 1 -C 3  alkyl radical and n is 1 or 2, are prepared by reacting phosphorus in gas or vapour form with an alkyl chloride (RCl) in gas or vapour form in the presence of an active carbon catalyst. The phosphorus gas or vapour may be mixed with one or more carrier gases, e.g. an excess of the alkyl chloride reactant in gas form, an inert gas (e.g. H 2  or N 2 ) and hydrogen chloride. Specified alkyl chlorides are methyl, ethyl and propyl chlorides. The reaction is preferably carried out inside a graphite-lined shaft furnace supplied continuously with a charge formed of active carbon and reaction components which may be passed either in the same direction or in opposite directions through the furnace. After reaction, the products and the inactivated active carbon catalyst are continuously removed from the furnace.

Abstract: 1,075,792. Aircraft windscreen shields. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. May 1, 1964 [Oct. 23, 1963], No. 41840/63. Heading B7W. An aircraft windscreen shield movable downwardly from a position in front of the windscreen completing a streamlined shape, to a position at least partly within the aircraft nose, exposing the windscreen 11, comprises a rear part 16 adjacent the windscreen and movable forwardly and downwardly, and a front part 15 pivoted to the nose about a lateral axis 18 at its front so that it can be swung downwards into the nose. In addition, the nose may be drooped to improve forward vision for landing and take-off. In the Figure, the parts 15, 16 are shown in the cruise position in full lines. Part 16 may have small windows in its sides to give limited forward visibility. To retract the shield, a jack 26 is retracted, pulling on a beam 30 pivoted to part 15 at 23 and connected by link 22 to part 16. A strut 31 extends between pivot 23 and a pivot 32 fixed relative to part 16, so that as part 16 slides down a guide 37, part 15 swings down to overlie part 16 (chain-dot line positions). Extension of jack 41 droops the nose about pivot 13, and further lowers the screen. The shield may alternatively be retracted by an electric motor drawing part 16 down guide 37 through a rack- and-pinion. A lost motion mechanism may ensure that part 15 does not swing down until part 15 is retracted. An emergency manual control may be connected to the cockpit.
