Title: Vehicle wheel brake cooling system
IPC: F16D65/78
Filed: 1970-05-21
Abstract: 1301035 Cooling vehicle brakes; indicating brake over-heating GENERAL MOTORS CORP 21 May 1970 [2 June 1969] 24589/70 Heading F2E A vehicle front wheel brake cooling system comprises the brakes of the two wheels, one of these having a wheel-driven cooling-fluid pump, a cooling-fluid container in at least two parts, a cooling-fluid heat-exchanger, and conduit connections permanently connecting these structures in a loop in uninterrupted continuous series fluid flow, as shown and to be described. A wheel-driven pump 12, in brake 10 only, forces coolant (e.g. an oil) through a ballast tank 22, another brake 14, a heat exchanger 18 and a coolant reservoir 16 back to brake 10 in series flow. Preferably the heat exchanger 18 is associated with the vehicle radiator 20. Preferably the wheel associated with brake 10 is on offside wheel because such a wheel is less likely to skid, or likely to skid for shorter periods, than a nearside wheel. The pump is geared to be driven at a speed higher than that of the wheel. The ballast tank 22 provides a sufficient volume to ensure that during a high speed stop coolant will not be circulated more than once. Overheating of the brakes due, e.g, to extreme braking or to loss of coolant causes overheating of the liquid in the vehicle radiator 20, so the radiator-temperature warning-indicator, (not illustrated), indirectly indicates such brake overheating. When the vehicle is being driven without the brakes being applied, the brake cooling system adds a substantial cooling capacity to the vehicle cooling system, and in cold weather the vehicle radiator water keeps the brake coolant warmer then is usual.

Abstract: 1,135,746. Feeding sheets. RANK XEROX Ltd. 14 Dec., 1965 [31 Dec., 1964], No. 24630/67. Divided out of 1,135,742 Heading B6B. In apparatus for separating sheets from the top of a stack, double separation is prevented by mounting at each side of the front of the stack a sheet-restraining element comprising a tubular bracket, such as 356, secured to an adjustable side-plate confining the stack, and housing a vertically movable plunger 354. The plunger has a radial slot 360 within which is fitted one leg 361 of a bent element 362 which faces the top front edge of the sheet stack, and has a tongue or snubber element 358 thereon which is adapted to rest, under gravity, on the corner of the top sheet of the stack. The parts 358, 361, 362 can be a unitary structure stamped from sheet material. When the top sheet of the stack is moved forward by friction rollers (367, Figs. 1 and 2), the leading corners of the sheet engage the elements 358, and the sheet will buckle upwardly and inwardly before final separation from the stack. The lower ends (364) of the two plungers are rounded and made of polytetrafluoroethylene, and the plungers are automatically raised by the engagement of these ends with inclined plates (365) when the tray (20) for the sheet stack is withdrawn. As described in Specification 1,135,742, the apparatus is used in xerographic reproducing apparatus, and the sheet stack is supported in a tray (20) having upright sides (292, 293, Fig. 2) which can be moved toward and away from each other symmetrically about the centre of the tray by a linkage system. Further, the tray (20) is moved upwardly automatically, to maintain the top of the sheet stack at a substantially constant height, by a motor drive and switching arrangement.

Title: Process for the production of esters
Inventor: CROCKER HENRY PETER
IPC: C07C69/80
Filed: 1960-07-16
Abstract: Esters of dicarboxylic acids are produced by hydrobrominating a terminal olefin to produce a terminal bromide, contacting the terminal bromide with an inorganic salt of a dicarboxylic acid in the presence of an organic base, preferably under an inert atmosphere, to produce an ester, reacting the inorganic bromide also produced with sulphuric acid to form HBr, and recycling recovered HBr to the hydrobromination stage.  The terminal olefin preferably contains 6 to 20 carbon atoms and may be, for example, hexene, 2-ethylhexene, octene, decene, hexadecene or styrene. Dicarboxylic acids specified are phthalic, isophthalic, terephthalic, sebacic, maleic and isosebacic acids.  The hydrobromination may be carried out by reacting the terminal olefin with HBr in the presence of a free radical initiator, e.g. oxygen, ozonised air, ozonised oxygen, a peroxide or ultra-violet light.  The organic base present during the reaction between the terminal bromide and the dicarboxylic acid salt, a tertiary base, e.g. trimethylamine or triethylamine, or a quaternary ammonium salt, e.g. the product of triethylamine or triethylamine with the terminal bromide, although N-methyl morpholine, N-ethyl piperidine, piperidine, dimethyl formamide, N : N-dimethylcyclohexylamine are also used in the examples.  The proportion of catalyst may vary from 0.01% to 10% by weight of the total weight of the reactants.
