Abstract: 1350995 Toothed gearing; differential gear SKF INDUSTRIAL TRADING & DEVELOPMENT CO NV 29 June 1971 [30 June 1970] 30447/71 Headings F2Q and F2D In a motor-vehicle conventional type bevel differential gear 4 driven by the usual crown wheel 3 and pinion 6 from the usual propeller shaft (not shown), the pinion 6, pinion shaft 7, propeller shaft connecting flange 9 and roller bearings 15, 17 form a unit which after its assembly cannot be taken apart. As shown, when the parts are assembled together, finally putting the cylindrical sleeve 8 of flange 9 over the end of pinion shaft 7, the bearings 15, 17 are preloaded by compressing the flange 9 and pinion 6 towards each other such that when the correct preload is achieved the sleeve 8 and shaft 7 are permanently connected by electrobeam or spin welding. Fig. 2 (not shown) illustrates a similar but more compact version in which the flange (22) is formed with a sleeve (21) and is spigoted on the pinion shaft (20), the ball bearing races being directly formed in the surfaces of the pinion shaft and sleeve and in an outer housing (25, 26) shimmed and bolted to the main housing (27), the bearings being correctly pre-loaded when the shaft and sleeve are abutted and welded together. Figs. 3 to 5 (not shown) show various alternative arrangements in which the pinion and connecting flange are forged as one piece, the pre-loading of the bearings being effected by the insertion of the balls during assembly. Fig. 4 illustrates an arrangement in which the ball bearings are arranged at each end of the pinion teeth in a supporting housing having an opening through which the crown wheel engages the pinion. In Fig. 5 the pinion flange is formed as a yoke end for the propeller shaft universal joint.

Title: Sewage treatment plant - using sloping archimedean screw for segregation of suspended particles of different specific gravities
IPC: B01D21/00
Filed: 1972-09-13
Abstract: Raw sewage after passing through initial sand filter beds is fed from a trough into a tank from which an Archimedean screw rises gently upwards within a semicircular floored gutter, the profile of the worm having a defined clearance from that floor to form a bed of sand and heavy particles forwarded along the gutter to discharge, after drainage in a section of the gutter above the water level, into collector vessels. The shaft of the worm is in bearings at both ends to maintain a constant spacing as above, and is driven at adjustable speed. The tank has an adjustable weir for effluent into a collector tank at the lower end of the gutter section. A washing water spray is fitted above the upper part of the worm and there is a compressed air feed into the lower part of the gutter for breaking up caked sand deposits. The lighter org. material in suspension in the filtered raw sewage is carried over with the effluent for subsequent treatment.

Title: Polycarbonate prodn. - by phosgenating crystal hydrates of alkali salts of aromatic dihydroxy cpds in org suspension and polycondensing
IPC: C08G64/06
Filed: 1975-01-28
Abstract: Polycarbonates are made by interphase polycondensn. by phosgenation of alkali salts of aromatic dioxy cpds. (I) in the presence of a catalyst (II) and a chain stopper (III), whereby the (I) has the formula where R = -C(CH3)2- or cyclohexyl, R' = Cl or Br, M = Na or K, n = number of mols. of water in the crystal hydrate, m = 2, and the phosgenation is carried out with a suspension of one or two of the cpds. (I) in org. solvents such as methylene chloride or a mixt. of methylene chloride with high boiling chlorinated hydrocarbons at 5-40 degrees C to form oligocarbonates, and the oligocarbonates are subsequently subjected to polycondensation in the presence of a 5 to 20% aq. soln. of caustic alkali used in amts. of 0.3-0.7 mol per mol. (I) to form the polycarbonate. The phosgenation is carried out in the absence of water and free alkali, which prevents oxidative discolouration of the prod. compared to prior art processes, so that an inert atmosphere is not required for the process; second stage of the reaction is conducted with small amts. of water, thus reducing the water usage in the process and reducing the hydrolytic loss of phosgene.

Abstract: 1473263 Production of ethers TEXACO DEVELOPMENT CORP 4 Nov 1975 [2 Dec 1974] 45718/75 Heading C2C An ether is prepared by (a) reacting a watersoluble alcohol as first reactant with an olefin or a water-insoluble alcohol as second reactant in an inert hydrocarbon solvent having 3 or 4 carbon atoms and in the presence of a solid etherification catalyst, thereby forming a reaction mixture including unreacted first reactant and product ether containing moieties from the first reactant and the second reactant, (b) contacting the reaction mixture with an aqueous extractant in the presence of the inert hydrocarbon, thereby forming an aqueous extract containing the first reactant and a raffinate containing rhe inert hydrocarbon and product ether, and (c) recovering the raffinate. The ether may be recovered from the raffinate, e.g. by fractionation. The first reactant may be a monohydric alcohol (e.g. a C 1 -C 6  aliphatic alcohol or benzyl alcohol) or a polyhydroxy alcohol, a number of which are listed; in the examples, methanol is used. The second reactant is for example a monoolefin i.butene, i.pentene, i.hexene, styrene or phenylpropene) or a di- or tri-olefin; alternatively it may be for example a C 5 -C 10  alcohol; the use of isobutene, is exemplified. The inert hydrocarbon is for example n.butane or isobutane. When the first reactant is isobutene, it may be admitted to the reaction as part of a refinery stream containing butanes; n.butenes present may also be classed as inert hydrocarbons in this case. The catalyst is for example a sulphonated coal or a sulphonated synthetic resin, e.g. a divinylbenzene-crosslinked polystyrene. A flow diagram of a suitable apparatus is given.

Title: Motor vehicle infinitely variable transmission - has adjustment system which supplies pressure to control chamber at or above set value
IPC: F16H61/662
Filed: 1977-08-02
Abstract: The system adjusts the ratio of an infinitely-variable transmission used in a motor vehicle, this being determined by the gas pressure in the engine inlet manifold, which pressure is transmitted to a control chamber. With pressure in the manifold above a set value, the pressure signal transmitted to the chamber is at the same level as that in the manifold. With it below this value, the pressure signal is the same as the set value. The set value can be roughly 0.7 atmospheres, and the gas flowing to and from the chamber can be throttled to different degrees. Atmospheric pressure can be supplied to the chamber whenever the accelerator is pressed right down.
