Patent GB-879242-A (GB)
Title: Improvements in and relating to the production of alcohols
Inventor: MARSHALL DENNIS
Filed: 1958-05-12
Abstract: Alcohols are produced by reacting a boron hydride with an olefine to give an alkyl borane, oxidising the alkyl borane with an oxygen-containing gas to form an oxidation product containing about 3 atoms of oxygen per atom of boron, and treating the oxidation product with a hydrolysing agent or an alcohol to produce an alcohol in which an alkyl group of the alkyl borane is linked with a hydroxyl group. The preferred olefines for use as starting materials are normally liquid mono-olefines containing 7-20 carbon atoms.  The reaction between the boron hydride and an olefine is preferably carried out in the presence of a solvent, which is preferably a hydrocarbon, at a temperature in the range -40 DEG  to 200 DEG C.  The oxidation step is preferably carried out in the presence of a solvent, e.g. a hydrocarbon or an ether, at 0 DEG -150 DEG C. and the oxidation may be catalysed by metals of variable valency such as iron, cobalt and manganese and compounds of these metals such as the acetates and naphthenates.  When the oxidation product is treated with an alcohol a catalyst such as an acid, an alkali metal hydroxide or an alkali metal may be used.  The product is the desired alcohol and an alkyl borate derived from the added alcohol.  The alkyl borate may be treated with an alkali metal hydride to give an alkali metal borohydride which may then be converted into diborane, for example, by treatment with acid, which may be recycled to the first step.  If the oxidation product in the second step is hydrolysed, the preferred hydrolysing agent is water or an alkali.  Examples are given of the conversion of (a) 2-methylpentene-1 to 2 methylpentanol-1; (b) C6-C8 a -olefines to the corresponding C6-C8 primary alcohols; (c) heptenes to heptanols; (d) propylene trimer to nonanols; and (e) propylene tetramer to dodecanol.  Specification 879,241 is referred to.

Title: Improvements relating to vessels for containing liquids
Inventor: HAMILTON ALBERT FREDERICK WILL
IPC: F02K9/56
Filed: 1948-06-07
Abstract: 662,436. Liquid fuel supply. MINISTER OF SUPPLY. July 29, 1949 [June 7, 1948]. No. 15366/48. Class 110(iii) Liquid fuel for rockets is stored in a vessel having a wall which is rupturable at a certain predetermined pressure, premature rupturing due to undesired surges in the liquid being prevented by a stout wall around the rup turable wall on the liquid side and separating the rupturable wall from the main body of liquid. In the stout wall is provided a passageway through which the liquid can have access to the rupturable wall, the passageway having associated therewith a movable valve member which by its inertia obstructs the flow of liquid when undesired surges occur but allows passage of the liquid to the rupturable wall when a predetermined pressure is applied to the liquid. The cylindrical vessel 1 has its bottom end closed by a thin rupturable aluminium disc 2 which is surrounded by a stout wall 3 on the liquid side of the vessel. In the short leg 4" of the inverted U-tube 4 is a valve 5 made of dense material and of sufficient weight to absorb surges of liquid. Liquid can flow through the openings 7 and 6, application of the predetermined pressure causing the valve 5 to lift so that the disc 2 is ruptured by liquid flowing through the opening 6. A catch or other device can be provided to retain the valve 5 in a raised position.

Patent GB-398297-A (GB)
Title: Improvements relating to clutch control mechanism for automobiles
IPC: B60K23/02
Filed: 1932-05-31
Abstract: 398,297. Controlling motor-vehicle clutches. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. May 31, 1932, No. 15417. Convention date, June 1, 1931. [Class 79 (v).] A fluid-pressure motor controlling the clutch of a motor vehicle is adapted to be put into communication with a source of super-atmospheric pressure to supplement the pressure of the ordinary clutch spring. The motor may also be connected to a partial vacuum so as to overcome, or tend to overcome, the clutch spring and disengage the clutch. In the construction shown in Fig. 2 a servo-motor 22, connected by a rod 26 to the clutch pedal 20, is controlled by a valve 33 whereby it can be connected either to the induction pipe 12 of the vehicle engine or to a pipe 44 leading from a supercharger 18 to the carburetter. The valve 33 is operated by a pedal 35 controlled by a spring 40 which holds the valve in the position in which the servo-motor is connected to the supercharger. The clutch spring 48 is only sufficiently strong for part of the full power to be transmitted. As the accelerator pedal 16 is depressed and the throttle is opened, the power transmitted increases, but as the supercharger pressure rises the piston of the servo-motor is pressed outwards to supplement the clutch spring pressure. When the clutch is to be disengaged the pedal 35 is depressed and the valve 33 connects the servo-motor to the induction pipe 12 in which, the throttle having been closed, there is a partial vacuum so that the piston of the servo-motor is drawn inwards to disengage the clutch. Alternatively, the servomotor may be arranged so as to be able only to tend to disengage the clutch, a light pressure on the clutch pedal 20 being then necessary to effect disengagement. In the construction shown in Fig. 1 the control valve 33 is dispensed with, and the servo-motor is permanently connected to the induction pipe 12. In this case when the accelerator pedal (not shown) is released there is a partial vacuum in the induction pipe and the servo-motor disengages, or tends to disengage, the clutch. When the accelerator pedal is depressed to open the throttle, as the engine speed rises the supercharger 18 increases the pressure in the induction pipe until it is greater than atmospheric and the servo-motor piston is then pressed outwards to supplement the clutch spring pressure. The Specification as open to inspection under Sect. 91 comprises also a construction similar to that of Fig. 1 except that a supercharger is not used, the servo-motor being used merely to disengage the clutch against the pressure of a strong clutch spring. This subject-matter does not appear in the Specification as accepted.

The outer surface of the upper shoe 33 is screwed on to a retaining ring 55 which has an inturned flange 56 the upper flat face of which abuts the lower flat face of a peripheral flange 52 of the lower shoe 34.  The outer diameter of said peripheral flange 52 being less than the inner diameter of the retaining ring 55.  The ram 23 is slidably mounted in a cylinder on a crosshead 24.  Extending downwardly from said crosshead are hollow struts 26 within which are slidably mounted supporting rods 26a. These latter support a ring pressure plate 27 which engages with the top surface 20 of mould 3 before the plunger 14 enters the mould 3 through the ring 27 which is held against the mould by springs 28. The apparatus is particularly for use when a series of such hollow moulds are equispaced around a table which has means for rotating it and presenting the moulds in turn under the plunger.  The apparatus may also be used for the manufacture of lenses.
