Title: Improvements in or relating to releasable fastening devices
Inventor: CHANARYN VICTOR
IPC: E05B65/32
Filed: 1958-10-22
Abstract: 871,895. Latches. WILMOT-BREEDEN Ltd. Oct. 15, 1959 [Oct. 22, 1958], No. 33711/58. Addition to 864,305. Class 44. A releasable fastening device comprises two parts between which relative angular and translatory movements occur in a common plane as the parts move to a relative coupling position, the formation of said parts being such that when in said coupling position surface portions thereof contact each other substantially at the centre of said relative angular movement and so that the reaction force therebetween, as a result of any tendency for relative translatory movement in the reverse direction to that occuring during the fastening operation, is aligned with the direction of said relative translatory movement and is directed substantially through said centre and imposes no turning movement tending to produce relative angular movement in the uncoupling direction. A cam 2 co-acts with a keeper 1 when an automobile door is closed, the cam rotating about an axis 6 as a lobe 4 co-operates with a bulge 8 of the keeper. A lobe 3 passes over a surface 10 and the cam returns to its resting position by the action of a spring 22 which urges a cam plate 19, attached by a spindle 15 to the cam, against a stop. The reaction force between the cam and keeper acts in a line passing through the rotational axis of the cam such that the latch may be released by rotation of the cam. This rotation may.be effected by a push button or by a remote control linkage connected to lever 34, both means causing cam plate 19, and hence the cam, to rotate. The door can be locked by a key from the outside while allowing the inside operating means to function, and also may be locked by a small handle from the inside while allowing the outside operating means to function. A safety lever situated at the edge of the door which is inaccessible when the door is closed prevents releasing movement of the remote control lever 34.

Title: Improvements in and relating to manufacturing processes
Inventor: LEWIS JAMES CYRIL ALEXANDER
IPC: C01B33/029
Filed: 1956-11-05
Abstract: <PICT:0878764/III/1> In the production of a semi-conductor element by thermal decomposition of a gaseous hydride, an elevated temperature, which is at least sufficient to decompose the hydride, is maintained in the decomposition chamber by a heating element consisting of the semiconductor element being produced, which is heated by the passage of an electrical current therethrough, the temperature and pressure in the chamber are such that the thermal decomposition of the hydride is substantially wholly a gas - phase reaction, the semiconductor element produced is swept to, and deposited on, the walls of the chamber, and the temperature at which the major portion of the decomposition occurs is such that the major portion of the semi-conductor element is deposited on the walls in a sintered, readily-removable, form.  Pure mono-silane prepared as described in Specification 878,763 enters at A quartz decomposition chamber B, which is sealed by water-cooled metal endblock J and metal cone R, and contains high purity silicon rods C, D, fixed in slidable clamp E1, and fixed clamp E2, respectively.  Rods C, D are first heated until the conductivity is sufficient, either by directing an infra-red source by elliptical, or parabolic mirrors thereonto, or by creating an arc between the rods, when C, D are firmly contacted, and the current passed through for further heating.  The silane is decomposed and silicon is deposited on the walls of B first as an amorphous layer and then as sintered flakes.  Quartz protecting shield L prevents silicon deposition in the lower part, and hydrogen formed is withdrawn through F by vacuum pump.  The silicon may be doped with an additive element by admitting a gaseous hydride of the additive element, e.g. arsine or diborane, to form AS or B by decomposition under the same conditions.  Specification 878,765 also is referred to.

Title: A process for the production of dialkyl sulphoxides
IPC: C07C317/00
Filed: 1957-11-07
Abstract: Dialkyl sulphoxides are prepared by oxidizing dialkyl sulphides with a solution of nitrogen dioxide.  The solvent is preferably the sulphoxide obtained as reaction product, but other solvents, e.g. chlorinated hydrocarbons, may be used.  Excess dialkyl sulphide is preferably used.  The nitric oxide formed may be converted in a second vessel into nitrogen dioxide with oxygen or a gas containing oxygen and the dioxide separated from the waste gases by washing, preferably with the sulphoxide product, and recycled to the reactor. The oxidation of nitric oxide is preferably effected in a vessel larger in volume than the reactor. Any excess sulphide is separated from the sulphoxide, e.g. by heating and, if desired, by expelling with a gas stream.  Excess oxygen is preferably used for oxidizing the nitric oxide so that the waste gases contain free oxygen, preferably not less than 7 per cent by volume.  Nitric acid may be used as the source of nitrogen oxides.  An apparatus is described for the continuous production of sulphoxides.  Examples describe the oxidation of dimethyl sulphide to dimethyl sulphoxide.
