Abstract: Porous green ceramic parts may be prepared by componding 90 to 60 weight percent of a particulate ceramic material with 10 to 40 weight percent, on a dry basis, of a latex of a polymer. The compound is frothed, shaped and set. The green part may then be sintered. The process avoids the expense of preparing solid ceramic compounds containing waxes or sawdust which burn out to create voids. The process is useful to prepare ceramic filters, catalysts, or light weight metal ceramic foams.

Abstract: A composite thrust collar for a rotary shaft formed from a radial bearing in which the rotating shaft may rotate and at least one axial thrust collar preventing axial movement of the shaft, characterized in that the radial bearing or the axial thrust collar or collars has at least one boss and in that the radial bearing is fixed to the axial thrust collar or collars by welding along said at least one boss and in that said at least one boss interconnects with the radial bearing or axial thrust collar in such a manner that should the weld break the bearing and collar can not rotate nor be radially disposed relative to one another.

Abstract: The resistance to heat and light aging of webs of natural or synthetic fibers is improved by using as a binder a composition comprising a latex of a polymer containing a carboxylic acid functional group, which has been neutralized with a fixed alkali, preferably in conjunction with a latent acid.

Abstract: Split journal bearings having crush relief are made by a method using a special plating rack having urethane masks for covering the ends of the split bearings during electroplating. Split thrust bearings having flanges may also be made according to the present invention by providing masking elements between adjacent bearings to prevent overplating at the flange relief areas or at the flange groove. The method eliminates broaching and/or boring operations to form crush relief areas on bearings but instead provides the required relief areas through the exclusion of overplate from said areas by masking. The plating rack features adjustable masks which are adapted to receive bearings within a range of sizes.

Abstract: An engine bearing or bushing having a cylindrical inner bearing surface which is slightly offset relative to the outer surface of the bearing. The amount of offset is very small and the offset is in a direction generally away from the portion of the bearing exposed to the maximum load. The inner bearing surface is offset so that the oil clearance between a journal member and the maximum load portion of the bearing is minimized to reduce oil film pressure and increase oil film thickness in that region. The offset increases the clearance between the journal member and bearing at a low load area of the bearing to increase oil flow and reduce oil temperature. The transition from the high clearance area to minimum clearance area is uniform so that the oil film thickness will also increase uniformly to its maximum potential.

Abstract: A split multipiece flanged journal bearing for use as an engine crankshaft thrust-journal bearing or the like wherein the thrust flanges and journal bearing shells are semi-cylindrical and have interlocking means to prevent rotational motion of the thrust flange relative to the respective bearing shell and with potential replacement interchangeability so that any worn or damaged parts may be replaced without changing the whole bearing and so that any one or all thrust flanges may be replaced without removing the crankshaft from the engine and wherein the notch and interlocking lug at one end of a particular combination of thrust flange and bearing shell is of greater arc length than those at the other end to provide a fail-safe feature to assure correct assembly.
