Title: Methods of manufacturing semiconductor devices
IPC: H01L27/06
Filed: 1967-10-02
Abstract: 1,208,578. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 2 Oct., 1967 [5 Oct., 1966], No. 27517/70. Divided out of 1,208,574. Heading H1K. A method of manufacturing a semi-conductor device having a substantially flat silicon oxide surface layer comprises subjecting a semiconductor silicon body to an oxidizing treatment whilst a selected portion of its surface is masked against oxidation by means of a masking layer and causing an oxide of silicon to grow into the silicon at the unmasked portions until the grown oxide forms a layer which is sunk over at least part of its thickness in the body. The surface masking during the formation of the silicon oxide layer is provided by a layer of silicon nitride, and this mask is further used, after its removal over selected areas, for masking the exposed silicon surface during diffusion of impurities into that surface to form PN junctions in the body. For the production of a transistor, a second surface oxidizing treatment is performed to convert this selected surface portion, into which impurity has been diffused, into a second silicon oxide layer thinner than the previously grown oxide layer. The remainder of the surface mask is then removed and a further impurity diffused into the silicon surface. Specifications 1,208,574, 1,208,575, 1,208,576 and 1,208,577 are referred to.

Patent GB-705724-A (GB)
Title: Improvements in or relating to preparation of carbon bisulphide and active carbon
IPC: C01B31/08
Filed: 1951-11-26
Abstract: Carbon bisulphide and active carbon are prepared by reacting sulphur and acid sludge coke containing at least 5 per cent. volatile material at an elevated temperature.  The acid sludge is thermally decomposed to coke in two kilns; in the first kiln, acid sludge coke is introduced and heated either by combustion of part of the coke or by a flame, and the resulting hot coke is fed to the second kiln, where acid sludge is pumped on to it, and the resulting mixture is decomposed, as it passes through the kiln, with recovery of sulphur dioxide and coke at 250-300 DEG C., some of which may be returned to the first kiln.  The coke from the first kiln having 5-10 per cent. volatile content or that from the second with 10-15 per cent. volatile may be used for carbon bisulphide production.  The acid sludge coke may be mixed with sulphur and charged to a retort, which may have multiple hearths equipped with rabble arms, or sulphur vapours may be passed through or over the acid sludge coke in a retort or through a pipe containing a layer of the coke enclosed in two layers of pebbles, and in either case the acid sludge coke may be briquetted with a binder, e.g. acid sludge or starch.  Alternatively the acid sludge coke which has been ground may be reacted in a fluidized state in a conventional reactor with a mixture of sulphur vapour and fixed gas containing mainly hydrogen sulphide recycled from the carbon bisulphide recovery.  The carbon bisulphide is recovered in the usual way by passing the gases through a water-spray cooler, where most of the product is recovered by settling and decantation, and then through an oil absorbtion to remove the remainder.  The reaction temperature is 650-1000 DEG C. and there is preferably a 25-75 per cent. stoichiometric deficiency of sulphur. The fraction obtained overhead on air separation of the residual carbon consists of a hard, dense, active carbon containing 1-35 per cent. ash and/or 7.5 to 10 per cent. sulphur, and having a size 8-120 microns, and an iodine adsorption of more than 650 mg. per gm. and its activity may be further increased by activation in the presence of air or steam and/or carbon dioxide.

Title: Television system
IPC: H04N7/06
Filed: 1959-08-17
Abstract: 916,147. Multiplex radio signalling. RADIO CORPORATION OF AMERICA. Aug. 17, 1959 [Aug. 28, 1958], No. 28095/59. Class 40 (5). In a system for transmitting television picture and sound signals over a path having a frequency pass-band which is no wider than the bandwidth of the picture signal alone, the sound signal is translated to a single-sideband (preferably carrier-suppressed) signal having frequency components lying within the picture signal band and lying midway between two adjacent harmonics of the line-scanning frequency of the picture signal. A programme source 10 supplies the sound signal to a sound signal translator 13 over line 14, translator 13 supplying the translated signals to line 11 carrying the picture signals. Line 11 is connected, possibly over a micro-wave link, to a remote transmitting station at which a receiver 17 separates the translated sound signal and applies the original sound signal over switch 20 to the appropriate part of transmitter 12. The system may be used as a standby link in the event of failure of line 186 which normally carries the sound signal. In this case, with normal operation of line 186, the gain of generator 13 is reduced and the gain of receiver 17 is increased so that transmission of the translated sound signal over line 11 is at a reduced level. If line 186 fails, switch 20 is moved to the position shown and the gains of generator 13 and receiver 17 suitably adjusted so that sound transmission is effected over line 11. The necessary switching operations may be performed automatically. The maximum level of the translated sound signal in line 11 is about 5% of the total signal amplitude.

Title: Improvements in hose connections
IPC: F16L33/16
Filed: 1922-10-17
Abstract: 205,994. Andrews, G. T. Oct. 17, 1922. Joints with yielding inner part expanded; couplings, disconnectible.-A joint between a hose pipe carrying fluid under pressure and a rigid socket is made solely between the exterior surface of the hose and the substantially cylindrical surface of the socket, provision being made to prevent the hose being displaced by fluid pressure. In the form shown in Fig. II. mechanical means, namely the locking ring 6, which is pivoted at 7, is used to prevent displacement; the bore of the socket is also slightly tapered. In Fig. IV. to prevent displacement of the hose and to aid the fluid pressure to make a fluidtight joint, a groove 9 communicating with an orifice 10 is made in the socket, thereby ensuring that the pressure between the hose and the socket is not more than atmospheric. In the latter modification the ring 6 is retained but it is normally vertical and only comes into operation when the hose is accidentally displaced.
