Title: Hydraulic Pressure Producing Systems
IPC: F15B1/02
Filed: 1979-09-06
Abstract: A reciprocating piston 2 operated by a spring 3 and a cam 5 draws hydraulic fluid from a reservoir 24 and delivers pressurised fluid to a hydraulic accumulator 13. When the pressure at the accumulator reaches an upper limit a piston 18 unseats a valve 19 and consequently a valve 16 connects a pressure line 11 to the reservoir and the accumulator to a servo-motor 26, 27 through a pressure-regulator 28. The servo- motor thus separates the piston 2 from the cam 5 and so interrupts the pumping action. In other embodiments, Figs. 2 and 3 (not shown), the servo-motor operates a clutch through which the cam is driven. <IMAGE>

Abstract: 794,685. Unsaturated diols. BADISCHE ANILIN- & SODA-FABRIK AKT.-GES. July 30,1956 [Aug. 2, 1955], No. 23413/56. Class 2 (3). Unsaturated diols of the formulµ: are isomerized or converted into a mixture of I and II or III and IV by treatment with a small quantity of a mercuric salt, e.g. the sulphate, chloride or acetate. A little mineral acid, in particular sulphuric, may be added if desired, in which case mercury oxide may be used to form. a salt in situ. Water and, if necessary, saturated alcohols, alcohol-ethers or cycloethers are added to dissolve the unsaturated diol. In general about 0.1 to 10 per cent by weight of mercury salt, based on diol, is added, and about the same quantity of concentrated sulphuric acid. If little or no water is added, divinyldioxane-(1,4) is formed. The products of the reaction are easily separable by fractional distillation. The process may be carried out continuously. In examples, the isomerization of butene-diols is carried out by boiling under reflux with mercury salt, with or without acid and water, or by standing at 25‹ C. with mercury sulphate, water and sulphuric acid.
