Abstract: 1372184 Gas burners BRITISH GAS CORP 30 Nov 1971 [5 Sept 1970] 42640/70 Addition to 1243626 Heading F4T A nozzle mixing tunnel burner (Fig. 1) comprises a refractory body having a bore 19 forming a combustion chamber 20, a nozzle core 22 having a gas supply bore 23 which discharge through radial parts 24, the gas flow being induced by the passage of air through an annular slot 26 formed between an aperture 18 in a plate 21 and a rib 25 on the nozzle core 22, the air expanding into a chamber 27 and mixing thereon with the gas, the mixture burning beyond the end face of the core 22. The part of the bore surrounding the core 22 may be formed by a metal bush lining a counterbore in the refractory body, and this bush may also extend through the plate 21. The position of the slot 26 may be varied between that shown and a position in which the rib 25 is dispensed with and the aperture 18 in the plate 21 is correspondingly' reduced. The nozzle core 22 may be held in place by radial ribs in the slot 26 or upstream thereof or by a separate apertured plate surrounding the core. Alternatively the slot 26 may be replaced by a series of separate apertures arranged in a circle. In Fig. 13 there is shown a linear type of burner producing a flat flame and this comprises a rectangular box 32 having an air manifold 34 and a fuel manifold 35. The air passes through a slot 41 expanding into the chamber 27 and mixing therein with gas drawn through a row of parts 43 leading from the manifold 35, the mixture then passing to the combustion chamber 20. The slot 41 may be replaced by a line of circular apertures.

Title: Improvements in or relating to the production of two or more stencils in mutual register
Inventor: DRAKE CYRIL FRANCIS
IPC: H01L21/00
Filed: 1959-12-24
Abstract: 867,559. Photographic production of two or more stencils in mutual register. STANDARD TELEPHONES & CABLES Ltd. Dec. 24,1959, No. 43887/59. Class 98(2) Two or more masks or stencils with cut-out portions in registered relationship are made by producing an initial photographic film having regions corresponding to the cut-out portions of the respective stencils in different colours, photographing this on to further films or plates each to produce images corresponding to one only of these colours and hence one only of the stencils, and using these films or plates to produce the stencils by a photomechanical technique. As shown Fig. 1(a) is a large scale master drawing intended for the stencils to make a plurality of identical semiconductor devices having groups each with a blue area 2 for the emitter region of one of the devices and red areas 3 corresponding to ohmic contacts, this is photographed on colour reversal film to produce the colours in reduced scale on an opaque background, such constituting the initial photographic film referred to above; and this is photographed with coloured lights on to panchromatic plates to produce the results of Figs. 1(a), 1(b), having, respectively, black areas 5 and 7 corresponding to red areas 3 and blue area 2. The further procedure is to print these plates on to separate molybdenum sheets coated with light sensitive glue or resin, develop away the unexposed parts and etch through the underlying sheet-portions, area 8 of the latter figure dropping out in such etching. The semiconductor devices may then result from evaporating processes effected through the pair of stencils. With Fig. 2. a single master drawing is used to produce multiple images by a step and repeat process. In another alternative masks of similar nature may be made in the form of oxide layers directly on the surface of semiconductor material.

Abstract: 1341976 Coffee brewer VENDO CO 27 Sept 1971 [16 April 1971] 44834/71 Heading A4E A beverage brewing and dispensing apparatus comprises a source of brewing water 132, a source of brewable grounds 138, a brewing receptacle 44 having inlet and outlet openings in the upper and lower portions respectively, a fine mesh steel screen filter 50 across the outlet opening, a pump 126 driven by a motor 128 and connected by a conduit 122 to the outlet opening of the receptacle 44 and to a discharge spout 66 which is movable between a recirculatory position in which liquid is discharged from the spout into the receptacle and a delivery position in which the liquid is discharged into a funnel 62 for delivering the liquid into a cup. The screen filter 50 is contained in a bottom assembly 36 against which the receptacle 44 is normally held in sealing engagement. The receptacle 44 is raised after dispensing the liquid to allow a scraper 114 to move across the screen 50 to remove the spent grounds. The raising of the receptacle 44 and movement of the scraper 114 are controlled by an upper track (100b-107a) Fig.2 (not shown) and lower track (120) Fig.4 (not shown) respectively of a first cam section 86. Movement of the spout is controlled by a follower 102 in a second cam section (88). The two cam-sections (86, 88) and four cams (90-96) are mounted on a shaft (80) driven by a motor (84) and one revolution of the shaft completes the operative cycle of the apparatus. The cams (90-96) control the energization of the power circuit for the motor (84), the operation of a solenoid 136 to dispense the water, the operation of an auger 140 to dispense grounds and the energization of the motor 128 to drive the pump 126. The second cam section (88) may be rotated relative to the first cam section (86) and secured by a screw (121) Fig.6 (not shown) to vary the time allowed for recirculation of the liquid, before movement of the spout to dispense the liquid, and thus vary the strength of the brew.
