Granted: 1993-06-19
Abstract: A dry rolling element bearing assembly for rotatably mounting a flight vehicle engine shaft to a housing. Rolling elements (such as ball bearings) are positioned between inner and outer races. Stop devices axial position the inner and outer races. A mounting device positions the inner race radially outward from the shaft so as to create a first annular air space between them. The mount has a flexible portion and has a support ring portion which contacts the outer surface of the inner race with a radial interference fit. A similar mounting device positions the outer race radially inward from the housing. Air directing devices direct cooling air impingingly against bearing surfaces.

Title: Exhaust dyeing of flat textile fabrics - with initial low dye concn. and constant addn. during the process
IPC: D06B21/02
Filed: 1977-05-27
Granted: 1985-05-28
Abstract: Fabrics are piece dried by the exhaust process, the dye is first added to the bath at dyeing temp. and its concn. during the exhaust phase is less than 10% (pref. 0.1-1%) of the usual initial concn. The dye concn. is kept at just over (pref. not more than twice) the respective equilibrium concn. in a fully-exhausted bath, by continuous addn. of a liquid dye concentrate to the circulating dye liquor. Used for dyeing of continuous lengths of fabric, esp. in machines using 'short' dye baths, i.e. ratios of dye liquor to fabric of 10:1 or less. Esp. suitable for dyeing polyester fibres, opt. in blends with staple rayon, cotton or wool, under high temp. conditions. Levelness of shade and depth is greatly improved and coagulation of the dye in the bath prevented. Very 'short' liquor ratios of 3-6:1 can be used and dyes with high affinity and exhaust rates, allowing dyeing times to be further reduced. Since rate of exhaustion is controlled by dye addn. and not by heating rate, very fast heating e.g. with high pressure steam, may be used.

Abstract: 1523047 Cation exchange membranes for brine electrolysis cells ASAHI KASEI KOGYO KK 2 July 1976 [9 July 1975(2) 31 March 1976] 27654/76 Heading C7B [Also in Divisions B5 and C3] Electrolytic cells, especially for brine, have the anode and cathode compartments separated by a cation exchange membrane comprising a fluorocarbon polymer containing pendant carboxylic groups of formula -OCF2COOM, where M is hydrogen, ammonium, quaternary ammonium or metal. The said groups are obtained by reduction of -OCF 2 CF 2 SO 3 X groups (see Division C3), and the membrane may contain residual groups of this type. Preferred membranes contain -OCF 2 COOM groups on one surface, which faces the cathode, and -OCF 2 CF 2 SO 3 M groups on the opposite surface. The membrane may be formed from a single film, or may be a composite of two polymeric films, and in either case it may further include a reinforcing layer, e.g. a fabric formed from PTFE fibres. The 27 specific examples describe a variety of such membranes and their application in the electrolysis of brine, the starting copolymers being of tetrafluoroethylene and perfluoro (3, 6-dioxa- 4-methyl-7-octene sulphonyl fluoride, in some cases with a further monomer which is hexafluoropropene, perfluoropropyl vinyl ether or perfluoro- 3, 6-dioxa-5-methyl-nonene-1.

Abstract: DIFFUSER CONSTRUCTION FOR A CENTRIFUGAL COMPRESSOR Constant flow width through the last stage diffuser of a centrifugal compressor is maintained against widening by the forces of differential pressure via a diffuser defined between oppositely positioned radial faces of a diaphragm and an annular diffuser plate secured spaced from the diaphragm at the desired with. Enabling the diffuser plate to withstand width deflection and/or enlargement is a pressure balance imposed against the rear surface of the plate as compared to the pressure level incurred from the gas flow at the front surface facing the diaphragm. This is achieved by a sealed radial cavity exposed to the rear surface of the plate and in continuous pressure communication with the front surface through a plurality of vent holes extending therebetween.
