Title: Improvements in or relating to automatic gear changing mechanism
Filed: 1932-12-22
Abstract: 415,395. Automatic gear - changing mechanism. RUSSELL, H., 152, Cross Road, Coventry. Dec. 22, 1932, No. 36270. [Class 80 (ii).] In an automatic gear-changing mechanism a selecting member is displaced by fluid pressure proportional to the speed of the engine, which displacement varies the resistance to the flow of the said fluid so that given positions of the selecting member correspond to given engine speeds, whilst fluid-operated detent means are also provided for temporarily arresting the selecting member at these given positions. A selecting piston 14 moves against a spring 16 and has a normally stationary core member 15 which is stepped in different diameters to vary the flow of the fluid from the supply pipe 1, and causes the piston to move to the right in a series of steps. A fluid operated detent 22 further controls this step-by-step movement. The selector piston operates, through the cam 13, a valve 3 for a reverse gear, valve 4 for a vehicle brake, valves 5, 6 and 7 for different forward speeds, and a valve 8 for the clutch, these valves supplying fluid to suitable operating mechanisms. The operation of the clutch and forward speed valves is automatic but for the reverse and brake valves the core member 15 and the selector piston is moved manually to the left. The mechanism may operate a sliding pinion type of gear box or an epicyclic box of the Wilson type in which case the selector piston carries a rack which rotates a cam shaft to cause selection or operation of the brake bands.

[Also in Division E1 and E2]  An anchorage device for a plurality of substantially parallelly arranged prestressing elements in the form of individual wires, rods or wire-ropes, comprises a female part 1 having a tapered aperture la through which the elements are adapted to extend from each end thereof and a plug 2 having a tapered external surface adapted to wedge in the aperture 1a of the female part, there being provided in the plug a coaxial passage adapted for reception therethrough of the elements and there being further provided at least one non- annular division member 4 insertable in the passage in the plug, the plug and division member or members being independently movable axially of the aperture in the female part and the arrangement being such that after tensioning the elements by means acting to draw the same through the aperture in the female part in one direction, the plug is movable jointly with the division member or members into the aperture in the female part in the other direction thereby to clamp and hold the tensioned elements in the aperture of the female part so that each element is engaged at least by a surface of the plug or of the, or one of the, division members. In the construction shown in Fig. 1 which is for use with wires or rods, two division members are used each of which is serrated on both sides and the plug which is in two parts is also internally serrated so that each wire or rod is engaged by two serrated surfaces. Two forms of serration are described, one in which the surfaces of the serration are symmetrical and the other in which they are asymmetrical. Each division member has two lugs 4a so that the member bears on the female part 1 and remains fixed in position while the plug is driven into place. In a modification of this construction the division members bear on the plug so that they move with the plug; this construction is used both with wires or rods and with wire ropes. Constructions are described for gripping numerous different numbers of elements from three up to twenty-seven and using from one to six division members and with the plug having from two to six parts. In the majority of the constructions the tapering cavity in the female part is frusto-conical in shape but in one construction this is modified so that the cavity has flat portions joined by curved portions and the plug is similarly modified.

Title: Process for the production of phenylglycols
Filed: 1955-12-29
Abstract: Phenylglycol and its nuclear alkyl substituted derivatives are prepared by reacting styrene oxide (or the corresponding derivative thereof) in the liquid phase with at least the stoichiometric amount of water in the presence of an acid catalyst, preferably at a temperature below 100 DEG  C.  Specified catalysts are sulphuric, oxalic, phosphoric, perchloric and organic sulphonic acids, nickel sulphate, zinc sulphate, potassium bisulphate and finely divided silica.  The process can be operated intermittently, or continuously, in which case the dilute glycol solution obtained is constantly removed from the reaction vessel and concentrated, e.g. by azeotropic distillation with an organic solvent, particularly benzene.  In examples: (1) styrene oxide is added dropwise with stirring to water containing a little H2SO4, maintaining temperature at 40-45 DEG  C., the excess acid is then precipitated as the calcium or barium salt and phenylglycol isolated from the remaining solution by concentration in vacuo and distillation or recrystallization; (2) as in (1) but effecting the reaction at 70-75 DEG  C., neutralizing with sodium bicarbonate and cooling to 10 DEG  C. when phenylglycol crystallizes, the mother liquid being recycled; (3) a mixture of m- and p-methyl styrene is treated as in (2) to yield a mixture of m- and p-methylphenylglycols.
