Title: Plain bearings and methods for manufacturing the same
IPC: F16C17/10
Filed: 1963-08-10
Abstract: A plain bearing has an outer annular member and an inner annular member which are relatively rotatable and are mounted coaxially one within the other, one annular member having a circumferential and substantially radially extending projection engaging in a correspondingly shaped circumferential groove in the other annular member, the projection and groove having a prescribed clearance therebetween, and a circumferential channel being provided in one or both of the members to form an annular space for lubricant at the radially inner end of the projection. To facilitate assembly of the two members either the outer or inner member is formed by two complementary portions which are adhered together while the members are in the assembled position or one of the members is deformed into position by pressure. In an embodiment, an outer annular member (3) is mounted in an inner annular member (2) which comprises portions (1) and (4), Fig. 1 (not shown), the portions being attached together by a synthetic resin material which is forced through an aperture (6) into an annular recess (5). An annular space (9) is provided in the members (2, 3) to which lubricant is supplied through radial ducts (8, 10). The lubricant, which may be circulated simply by centrifugal action or may be supplied to the ducts (8, 10) under pressure, also serves to cool the bearing. In another embodiment, a self-aligning bearing comprises the bearing in Fig. 1 (not shown) which is mounted in housing comprising portions (12, 15), Fig. 2 (not shown), which are attached together by synthetic resin being forced into an annular recess (16) therebetween. In a further embodiment, an inner annular member (2) has a groove (17), Fig. 3 (not shown), therein and an annular member is formed from a cylindrical sleeve (18), shown in broken lines, having a circumferential recess (21) on its inner surface, the sleeve (18) being deformed into position about the inner annular member (2) by a rotating roller (19), having a projecting surface (20) thereon. The housing in Fig. 2 (not shown) may be formed into position on the outer annular member (3) by rolling. The bearing surfaces may be formed with a number of recesses which act as passages for lubricant. This is effected in the case of an outer annular member (25), Fig. 4 (not shown), by machining flats (26) on its external periphery, forcing a sleeve (27) thereover so as to provide flats (7) on the inner periphery of the member (25).

Title: Method and apparatus for the automatic cleansing of the filter for a solvent,particularly in dry-cleaning plants
IPC: D06F43/08
Filed: 1967-07-26
Abstract: A filter used in the solvent circuit of a coin-freed dry-cleaning machine comprises a plurality of filter elements D, made of wire wound on flat frames of moulded plastics, having lozenge-shaped cross-sections and being radially arranged about and supported by two or three rotatable hollow shafts F. After a washing cycle, during which solvent passes continually through the filter and back to the washing tub, the solvent flow is stopped and the shafts are rotated or arcuately reciprocated by a common motor (64), creating turbulence in the dirty solvent around the elements and thereby washing the used, absorbent, filter aid and solids therefrom. Periodically a sludge outlet (72) in the housing floor is opened. In Fig. 2 and Fig. 3 (not shown) the elements D intermesh and turbulence is concentrated in zone H. In Fig. 4 (not shown) the elements of the different assemblies do not intermesh and there is less turbulence. Within the limits of the filter housing, additional filter elements may be added to each ring of elements, and further complete rings of elements may be mounted axially above the first on each rotatable assembly. The ends of elements open into hollow radial arms of plastics spiders between which elements are clamped, the spiders (G) open into the interiors of shafts F and these discharge filtrate by outlets (70). Sludge discharged by outlet (72) passes to a distillation plant which recovers the filter aid.

Patent ES-420084-A1 (ES)
Title: Reduction of pollutants in gaseous hydrocarbon combustion products
IPC: F23C6/00
Filed: 1973-10-30
Abstract: Fuel and less than the amount of air for stoichiometric combustion are injected into a combustion chamber so that the fuel rich mixture burns as a core in the combustion chamber. The balance of the air for substantially stoichiometric combustion is injected coaxially and rotationally as a sheath or vortex which surrounds the core. Where the core is hot and rich, there is little mixing of the sheath air and core gases and the available oxygen combines preferentially with fuel components other than nitrogen so that little nitrogen oxides are produced. After some heat is extracted from the gases in the core, more complete mixing of the sheath air and core gases occurs. Under these lean and cool combustion conditions, production of nitrogen oxides is also unsubstantial. Means for mixing the gas streams may be disposed adjacent the exit end of the combustion chamber when necessary to promote turbulence and further mixing of the air and hot gases for bringing about complete combustion of any residual combustibles. In the larger combustion systems within long furnaces means of promoting turbulence may not be required to complete combustion.
