Abstract: 1,058,063. Making bearings; jointing. W. SCHMIDT. Aug. 19, 1963 [Aug. 27, 1962; July 3, 1963], No. 32749/63. Headings B3A and B3V. [Also in Division F2] 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: Process for the manufacture of isoprene from 4.4-dimethylmetadioxane
Inventor: HELLIN MICHEL
IPC: C07C1/247
Filed: 1959-09-25
Abstract: Isoprene and formaldehyde together with small amounts of isobutene are formed from 4,4-dimethylmetadioxane in the vapour phase at elevated temperature in the presence of an inert diluent and phosphoric acid on silicon carbide.  The catalyst may contain 5-60% by weight of acid using a fixed bed and 0.5-5% using a moving or fluidised bed after drying at about 280 DEG C.  The catalyst is preferably continuously agitated either by a stirring device or by using a moving or fluidised bed, and may be regenerated by reimpregnation from time to time and, usually at less frequent intervals, heating in air to remove deposits prior to the reimpregnation.  The two regenerating operations may be performed in the same apparatus (see Group III).  Temperatures of 200-300 DEG C. are used at pressures up to 5 kg./cm.2, preferably atmospheric. Space velocities of 0.1-1 litre/hour/litre of catalyst are used.  The diluent may be nitrogen, water vapour or vapours of paraffinic or naphthenic hydrocarbons forming 35-95% of the total charge.  Heat is preferably supplied to the catalyst bed, e.g. by submerged heating coils rather than to the reactants.  Unconverted dioxane may be recycled and where the dioxane is obtained from isobutene as in Specification 825,034 the total effluent from which processes may be passed to the present process, formaldehyde and any isobutene formed may be recycled to the first operation.  The effluent is preferably cooled quickly to 80-20 DEG C. by intimate contact, e.g. in a countercurrent scrubber or an ejector, with the aqueous phase of the condensed product after it has been cooled.ALSO:<PICT:0874569/III/1> The cracking of 4,4-dimethyl-metadioxane to isoprene is effected in the presence of phosphoric acid on silicon carbide.  The catalyst may contain 5-60% by weight of acid when used in a fixed bed and 0.5-5% in a moving or fluidized bed.  The catalyst is regenerated by reimpregnation and, usually less frequently, by burning in air to remove deposits prior to reimpregnation.  The two operations may be effected in the same apparatus as the reaction, using a fluidized catalyst, as shown.  A mixture of 4,4-dimethylmetadioxane and steam enters by line 82 to contact the bed of catalyst 79.  The reactants leave by cyclone 85 and line 84.  The catalyst overflows into stripping zone 93 where it is stripped with steam from line 86, which also leaves by cyclone 85. Air is injected by line 89 to carry catalyst up into the burning zone 80, which is supplied with more air by line 91.  Water vapour and phosphoric acid are injected by line 95 to carry catalyst to the reimpregnation zone 81 into which catalyst also overflows from the burning zone 80.  The reimpregnation zone is fluidized by steam from line 98.  Regenerating gases and vapours leave by cyclone 101 and regenerated catalyst returns to the reactor by line 100.

Stroke, varying.-The supply of liquid to an evaporator is determined by the proportions of water and steam flowing through an aperture which is also dependent on the liquid level in the evaporator. The regulator shown in Fig. 1 is connected at 1 to the steam space and at 1<1> to the water space of the boiler to be controlled. A triangular opening (Fig. 1<a>) in a position wall 25 and apertures 27 provide the inlet to a nozzle 3 communicating with a worm 4 leading to a chamber 28 which has an outlet nozzle 21, and is connected by a pipe 9 via the valve 10 to a chamber 11 under a membrane 12. A container 30 is provided in shunt with the worm 4 so that the head of liquid is equalized therein. The membrane 12 actuates the valve spindle 14 and valve 13 against the action of a spring 15. The valve 13 controls the passage of feed water entering at 6 and passing through the chamber 5 to the boiler, through the valve 13. When water reaches the level A-A a mixture of water and steam flows to the worm 4. The quantity of water passing depends on the speed at which steam flows through the diaphragm which increases as the opening # becomes smaller. The pressure in ther worm 4 and under the membrane 12 is lower or higher as # becomes larger or smaller. Consequently by adjusting the tension of the spring 15 a condition of equilibrium can be established and a constant water level maintained. In a modification tho mixture of steam and water actuates a pump the stroke of which is dependent on the quantity of liquid carried along.
