Title: Improvements in or relating to steering gear for motor vehicles
IPC: B62D5/08
Filed: 1954-10-12
Abstract: 753,821. Vehicle power steering. SOC. ANON. A. CITROEN. Oct. 12, 1954 [May 10, 1954], No. 29389/54. Class 79 (5). In a hydraulic servo steering mechanism, the housing 3 for the control valves 19, 20 turns with the rotary part of the usual steering gear, and, when the steering column 2 is turned in order to actuate the valves, the fluid pressure applied to the servo cylinder is also applied to a chamber 191 or 201 to press on one of the valves and so react back on to the steering column to oppose the turning movement made by the driver. The column 2 carries a bridge piece 35 which connects with the valves through preset screws 36 and rounded tappet rods 37. Each valve controls one end of the servocylinder so that the valves are actuated differentially. The passages in the block 3 for the hydraulic fluid comprise pressure inlet 23, exhaust 26, and passages 29, 29<SP>1</SP> connecting with the respective ends of the servo cylinder. A distribution block is unitary with the housing 3 and is also coaxial with, and situated between, the column 2 and the usual steering gear. The servo-piston acts on the output lever of the steering gear.

A parachute hook comprises a hook 11 having an anvil 16, and a hook 12, having an extension 17, pivotally connected to the lip of the hook 11 at 13. Hook 11 has a shoulder below the anvil 16 against which a spring- loaded catch 18 on the hook 12 abuts, in the closed position, and is mounted on a crosshead between two harness straps 25. Release of the catch 18 by a pull-cord 22 allows hook 12 to pivot about 13, and a further pull ejects the link 23 of the parachute from the loops of the hooks. The link may be crank-shaped to allow connection to two parachutes.

Title: Improvements in or relating to crystal valves
IPC: H01L23/29
Filed: 1953-10-29
Abstract: 732,642. Semiconductor devices. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 29, 1953 [Oct. 30, 1952], No. 29867/53. Class. 37. [Also in Group V] In a method of making crystal valves to which a protective layer of a thermosetting material is applied the layer is hardened uniformly by subjecting it to a high-frequency electrostatic field. In the described embodiment a semiconductor body 3 with its contacting electrodes in position is placed in the cavity 2 in a block 1 of dielectric between condenser plates 4 and 5 which are connected to a high frequency source. The fluid thermosetting material in the cavity is heated by dielectric loss and the block 1 is cooled to ensure that the surface layer is the last part to harden. To reduce energy loss block 1 has a low power factor but must permit a strong field in the cavity. Suitable resins for both the block 1 and the protective layer are unsaturated polyesters and resins based on phenol and urea. Such resins are less lossy in the hardened than in the liquid state so that over-exposure to the field does no harm. By using the crystal as a plug in a cylindrical hole in such a mould the casing may be restricted to a layer on the upper surface to fix the electrodes.

Title: Improvements in or relating to an anhydrous grain-free grease and preparation of same
IPC: C07C51/41
Filed: 1954-10-20
Abstract: An anhydrous lubricating grease comprises an oleaginous liquid and 5-20 per cent by weight, based on the total composition, of an alkaline earth metal salt of a hydroxy fatty acid, this salt having been prepared from a hydroxy fatty acid containing at least 3 per cent by weight of an estolide of the fatty acid, i.e. an intermolecular polyester of the fatty acid.  In the case of a monohydroxy fatty acid containing 12-24 carbon atoms, the estolide has the formula: <FORM:0771797/III/1> wherein R is an aliphatic hydrogen radicle containing 1-21 carbon atoms, x is an integer having the value 1-21, the sum of x and the number of carbon atoms in R equalling 10-22, and n is an integer usually having a value of 2-5. The oleaginous liquid may be mineral lubricating oil or a synthetic lubricating oil, particularly an ester of an aliphatic dicarboxylic acid such as 2 - ethyl hexyl sebacate. Alternatively, a blend of mineral oil and synthetic oil may be employed.  Hydroxy fatty acids mentioned are 9-, 10- and 12 - hydroxy stearic acids, 9, 10 - dihydroxy stearic acid and 8 - hydroxy palmitic acid.  Alkaline earth salts of hydroxy fatty acids mentioned are calcium, barium and strontium 12 - hydroxy stearates, barium 9 - hydroxy stearate and strontium 10 - hydroxy stearate.  Mixtures of salts of hydroxy fatty acids may be employed, and mixed calcium-barium, calcium-sodium and calcium-lithium 12 - hydroxy stearates are mentioned.  The lubricating grease may contain additional ingredients such as oxidation inhibitors (e.g. diphenylamine, other amines or dialkylated phenols), extreme pressure agents, corrosion inhibitors, pour depressants and dyes.  A process of preparing the lubricating grease is described in which a minor proportion of the oleaginous liquid employed in the finished grease, water, the estolide-containing hydroxy fatty acid and alkaline earth metal hydroxide are mixed together at room temperature, the mixture is heated to effect saponification and is then dehydrated at a temperature below 285 DEG F., the dehydrated mixture is cooled and the remainder of the oleaginous liquid added during cooling.  The oleaginous liquid added during cooling of the dehydrated mixture may differ from that added initially.  Thus, mineral lubricating oil may be employed initially, while synthetic lubricating oil is added during the cooling. Alternatively, a paraffinic distillate mineral lubricating oil may be employed initially and a blend of the distillate oil and a residual mineral lubricating oil or petroleum cylinder stock added during the cooling.  In the examples, the preparation of lubricating greases from mineral lubricating oil and the calcium salt of an estolide-containing 12-hydroxy stearic acid, with or without the corresponding sodium salt, is described.  In some instances, the finished greases are alkaline.  For comparison purposes, the preparation of a lubricating grease from mineral lubricating oil and the calcium salt of estolide-free 12 - hydroxy stearic acid is also described.
