Abstract: 1,046,157. Etching. SIEMENS & HALSKE A.G. Feb. 25, 1965 [Feb. 26, 1964], No. 8106/65. Heading B6J. A semi-conductor body or bodies, e.g. silicon or germanium, is or are etched with a gas to form a volatile compound, e.g. silicon monoxide, which evaporates and is removed. In one form, silicon may be treated first with hydrogen to anneal it, and then with a mixture of water vapour and oxygen to form a layer of silicon dioxide. The pressure is then reduced and the silicon dioxide reacts with the silicon underneath it to form silicon monoxide, which then evaporates. The gas may be a mixture of water vapour, oxygen and nitric acid, and may be diluted with hydrogen, nitrogen, a rare gas, a halogen, or a mixture thereof. Alternatively, the process may be carried out in a single step. The apparatus comprises a quartz reaction vessel with inlet and outlet valves, which may contain an electrically heatable table on which the body is placed.

Title: Improvements in or relating to electric snap action switches
IPC: H01H37/60
Filed: 1944-05-03
Abstract: 585,590. Snap-action switches; thermal switches; press-button switches. THERMEGA, Ltd., and SINGLETON, S. A. May 3, 1944, No. 8351. [Class 38 (v)] A snap-action switch comprises a blade spring 5 fixed at one end in an insulating block 4 and carrying at the other end a movable contact 6 co-operating with a fixed contact 2 on a rigid strip 1, which also carries a tension or adjustment screw 7 pressing on the blade 5 through an insulating plate 8. A transversely-curved strip 10, fixed at 9 to the blade spring, is pressed by an adjusting screw 11 which in Fig. 1 is mounted on a bimetallic strip 3 and insulated from the strip 10 by a button 12, against the dimple 13 of the blade spring thus bending it to bring the contacts together. A rise in temperature causes the bimetallic strip to move inwards, thus increasing the curvature of blade 5 until at a preset temperature the spring 10 suddenly collapses about the fulcrum 13 and allows the spring blade 5 to straighten, thus opening the contacts. On cooling, a snap closure is obtained when the strip 10 suddenly straightens, a hook 16 restraining its subsequent opening motion at very low temperatures. The tension and adjusting screws may be interchanged, and greater sensitivity may be obtained by replacing the rigid strip 1 by another bimetallic strip. The block 4 may carry spring lugs 24 to locate the thermostat inside a glass vessel. In a further modification. Fig. 6 (not shown), the bimetallic strip is replaced by a leaf spring or rigid holder carrying a slidable insulating push button. Alternatively the push button and tension screw 7 may be interchanged to produce a switch requiring a heavy pressure but small movement to operate it.

Title: Improved method and apparatus for the manufacture of artificial edible sausage casings
IPC: A22C13/00
Filed: 1955-03-24
Abstract: <FORM:0791402/IV (a)/1> Artificial edible sausage casings not more than 0.016 mm. thick, for use in the production of small thin sausages, are formed by the steps (carried out at not over 25 DEG C.) of soaking pieces of animal hide or skin for a long time in milk of lime, removing and water-washing them, immersing them for some hours in a dilute aqueous solution of hydrochloric acid, washing them with water until the pH of the aqueous extract is 2.8-3.4, coarsely disintegrating them by passing them between fluted rollers, further disintegrating them by passing them through perforated plates having round holes of 1 to 1.5 mm. diameter, adding water to the fibrous mass thereby formed to reduce its dry content to 8-9.5 per cent, kneading the mass until it is homogeneous, passing the mass repeatedly through plates having slots which have a length of 6-10 mm. and a width not exceeding 0.22 mm., and finally extruding the mass through an annular passage, the width of the annular passage, including the annular extrusion nozzle or die, not exceeding 0.22 mm. and the walls of the passage rotating in opposite directions about the nozzle axis.  The length of the annular passage may not exceed 2.5 times the diameter of the outer ring of the annular extrusion orifice and its width may be 0.16-0.22 mm.  The walls of the passage may rotate at not more than about 60-120 R.P.M. for a production rate of 6-8 metres of casing per minute.  As shown in Fig. 2, the finely disintegrated fibrous mass is forced through the tube E, the tubular cavity of the tubular rotating core A and passages G into the annular chamber H between the core A and the tubular sleeve B of the extruder, which sleeve rotates in a direction opposite to that of the core and is supported in a stationary housing C.  From the annular chamber H the fibrous mass is forced into the annular passage D in which, as the result of the contra-rotation of the core A and sleeve B, the fibres of the mass are oriented in two directions crossing each other.  The fibrous mass is extruded from the outlet of the annular passage D to form a tubular casing which is inflated by compressed air supplied through a tube Z which communicates with an annular duct W in the fixed housing.  This duct in turn communicates with the short bent portion V of the tube F which is integral with and rotates with the core A and whose other end is open and flush with the face of the extrusion nozzle.  The end of the core A located at the duct W rotates in an air-tight running gland indicated generally at U and provided with resilient sealing rings T.  The fixed tube E and co-operating end of the rotating core A is provided with a running gland X having a grooved sealing ring Y.  The core A and sleeve B are rotated in opposite directions by means of the duplex bevel gear S.

Title: Improved method of and apparatus for vulcanising
IPC: B29C35/02
Filed: 1928-03-21
Abstract: 311,507. Gibbons Bros., Ltd., (Dressler, C.). March 21, 1928. Tunnel kilns; gases, supplying.-In the continuous vulcanizing of tyres &c. the articles, which may or may not be in moulds, are passed continuously through an elongated chamber in which they are gradually heated up and finally cooled. In the apparatus shown in Figs. 1 and 4, tyres in enclosed moulds are stacked on cars H, a member H<3> working on vertical guides H<2> being placed on top of the stack. The cars are introduced through side doors J and then pushed into the kiln by a hydraulic ram JA. The first portion of the kiln is heated by combustion chambers A<1> with hollow walls, the kiln atmosphere circulating by convection up through these walls and down through the tyre stack and car. The chambers have thermostatically controlled gas burners at each end and are arranged to be hotter at the entrance end. The products of combustion are withdrawn by a fan L. After passing the preliminary heating zone, the cars reach a mould-closing section, in which a hydraulic ram lifts the car and forces the cover member H<3> into contact with a fixed crosshead, and pass thence through a second heated zone similar to the first but shorter, and a third zone heated by sets of steam pipes D<1>. In the final zone the moulds are cooled by spraying them with water which is drained away and used as boiler feed water. In a modification, Figs. 16 and 17, the apparatus just described is provided with fans M which assist the convection currents, replace leakages in the kiln atmosphere and in emergency supply it with large quantities of cool gas. Above each fan is provided a chamber M<2> connected through normally open dampers O<z> with a, pipe 0 connected through a valve O<6> with a container O<4> for nitrogen, air or, as shown, the products of combustion from the chambers A<1>. The valve O<6> is normally almost closed, enough gas leaking past to replace leakage of the kiln atmosphere. In case of overheating, however, a thermostat which also cuts off the main fuel gas supply, opens the valve O<6> to allow large quantities of gas to pass and cool the kiln. The degree of cooling at different parts of the kiln is then controlled by adjusting the dampers O<2>. In a further modification, Figs. 19 and 20, the chambers A<1> are replaced by 6 inch metal pipes A<50> with individual and individually controlled gas burners A<51>. The pipes start in groups at various distances from the entrance and proceed to the end of the zone in question. Hollow baffles S<1> cooled by the circulation of the kiln atmosphere prevent direct radiation from the pipes to the moulds. In cases of abnormal heating, water is fed to the bottom of the kiln through pipes T, the resulting steam escaping through flap valves A<42>. The valves are provided with holes A<41> which allow a permanent leakage of kiln atmosphere.

Abstract: 1,162,349. Refining copper. A.W. SPITZ and M.I. SCHWAB. Feb.23, 1967 [March 23, 1966], No.8723/67. Heading C7D. In a method of refining black copper, copper scrap, copper alloys and copper-bearing mixtures containing impurities, a charge of the molten impure copper is exposed to oxygen in a rotating horizontal furnace. As shown, furnace A is rotated anti-clockwise on rollers 14, 21. Part of molten charge 10 is carried up on refractory lining 16 of the furnace and there reacts with oxygen atmosphere 12 introduced through inlet tube 23. Copper is thereby oxidized and on falling back into the charge exchanges oxygen with the impurities which rise as oxides to form slag 11. If the charge is introduced in solid form it is first melted by introducing a mixture of fuel (such as natural gas or propane) and oxygen through tube 23.
