Title: Improvements in porous metal journal bearings
Inventor: MORGAN VICTOR THOMSON
IPC: B29C49/26
Filed: 1955-04-23
Abstract: A method of providing a porous metal journal bearing 11 with a layer of poly-tetra-fluoroethylene in its bore comprises introducing P.T.F.E. foil 12 into the bore and applying radial pressure to the foil by the axial movement of a tapered tool 16 so that the foil is extruded into the pores of the bore of the bearing and <PICT:0798378/III/1> <PICT:0798378/III/2> <PICT:0798378/III/3> forms a thin layer of P.T.F.E. on the bearing surface, held in place by the extrusion.  During the process the foil is heated to a temperature of between 327 DEG  and 400 DEG  C.  In a modification, the ends of the bore are closed by plates 18, 19, Fig. 2, and hot fluid under pressure is introduced through a pipe 20 to apply the radial pressure to the P.T.F.E. foil 12.  Outlet ducts 21 are provided for the escape of gas expressed from the bearing.  In a further modification, radial pressure is derived from the differential thermal expansion of a cylindrical rod 22, Fig. 3, of a metal having a relatively high coefficient of thermal expansion, disposed in the bearing bore, and a housing member 13 of metal having a relatively low coefficient of thermal expansion. Specifications 657,080 and 657,085, [both in Group XXXIV], are referred to.  Reference has been directed by the Comptroller to Specification 731,348.

[Class 34 (ii).] Air has part of its natural content of moisture removed, and is then circulated through the tea-withering space, being heated without further dehumidification between successive passages through the withering space. Preferably a portion ofthe used air is at the same time replaced by dehumidified air. In the form illustrated, withering lofts 1, 2, 3 are connected to air ducts 10, 11 provided with dampers 12, 13 through fans 4, 5, 6 and 7, 8, 9 adapted to blow the air in either direction. Part of the air escapes through an open damper, and the remainder passes to the transverse shaft 14, in which is situated the condenser 15 of a refrigerating system. If this does not supply sufficient heat, an additional heater may be provided, or outside air may be led in. Air to replace that discharged is drawn in through tubes 19 past the cooling pipes 22 of the refrigerating system, and is supplied to the air circuit by the tube 17 in which a fan 24 may be provided. A passage containing electrical heating elements or humidifying nozzles may be arranged side by side with the shaft 14, from which the circulating air may thus be shunted. Automatic regulators 26, 27 sensitive to dry or wet temperature or the difference between these may be situated in the shafts 10, 11.
