Title: Air cushioning ball support bearing
IPC: B62D35/00
Filed: 1961-07-03
Abstract: 925,268. Bearings. A. P. PEDRICK. July 3, 1961, No. 23930/61. Class 12 (1). [Also in Group XXXI] A fluid bearing for a vehicle &c. has a spherical member A, of hard rubber or of synthetic plastics material, which is freely received by a spherical-shaped socket in a housing B of the vehicle and is in contact with the ground. When the vehicle is stationary, the housing B is supported by the spherical member A and when the vehicle is moving, pressurized air is supplied from a pipe C to provide a clearance between the member A and the housing B. The pressure of the air is adjusted according to the load carried by the vehicle so as to give the required clearance between the member A and the housing B. The vehicle may be tilted by pressurized air which enters a chamber D and expands a bellows E to raise a floor K. In an embodiment, two or more bearings are positioned at each side of a vehicle to support the main load. A single steering wheel is provided at the front end of the vehicle and closely-spaced driving wheels are at the rear which may form part of a disconnectable engine unit. The fluid bearings facilitate turning of the vehicle and air storage reservoirs are charged by an air compressor driven by the engine. When pressurized air is cut off the spherical members A are braked by making contact with the housing.

Abstract: 1,203,221. Drying coated strips; continuous strip heating furnaces. B. & K. MACHINERY INTERNATIONAL Ltd. 25 Aug., 1967 [27 May, 1966 (3)], Nos. 23976/66, 23977/66 and 23978/66. Headings F4B and F4G. In an apparatus for drying a coated strip, the strip is passed through an oven chamber where it is heated to evaporate solvent in the coating, by burners which are controlled by means sensing the temperature of the strip, and by a heated air stream passing through the chamber, the solvent vapours are carried by the air stream to a solvent burning means where the vapours are oxidized and the resultant oxdized mixture is passed through heat exchange means to heat air entering the chamber. In the embodiment shown in Fig. 1 a painted continuous metal strip is dried and cured by being passed through solvent removing oven chambers 11, 12 and curing oven chamber 13. The evaporated solvent is conveyed by air which has been preheated in heat exchangers 26, 30, being pumped through the oven chambers 11, 12 to burner unit 24 in which the solvent is oxidized. The oxidized effluent is used as the heating medium in heat exchanger 26 and then exhausted to the atmosphere. The supply of fuel to the gas fired infra-red burners 32, 33, which are pivotally mounted such that they can be activated to be directed towards or away from the strip, is controlled by means 58 sensing the temperature of the strip and means (not shown) for sensing the temperature of the ambient air in the oven chambers. The oven chambers have adjustable vents 63. The effluent burner unit 24 may comprise two porous plates 64 (e.g. silicone carbide or aluminium oxide) adjustable gas burners 68 and adjustable inlet 82. The unit 24 may comprise one porous plate (Fig. 7 not shown) or a porous barrier 77 (Fig. 8). When the strip is stopped, burners 36, 37 are moved away therefrom by hydraulic motors 34, 35 actuating linkage 38, 39 under control of a valve (54, Fig. 4) and a switch (56).

[Also in Division G1] In an arrangement for examining the ground edge facets of a razor blade a beam of coherent light is used to illuminate the edge and the reflected beams are used to determine the angles and widths of the facets by means of photodetectors. Beam 20 of coherent light is made to traverse path (a) and (b) alternately by means of split prism SP rotating about an axis normal to the paper. Beam (a) illuminates the whole width of the facets 13, 13a and reflects a beam 21 to detector P. Since the angle of the incident beam changes linearly with time; joints 24, 24<SP>1</SP> being conjugate with request to lens L2, the output beam rotates about the edge of the blade at substantially constant rate so that the angle of the facets can be determined. Beam (a) is produced by total internal reflection occurring in the prism. When the prism rotates further the beam passes through and is reflected by mirror M onto the edge of the blade. This beam travels at substantially constant rate across the facet and is detected at P1, P2 so that the facet width can be determined.
