Filed: 1927-07-29
Abstract: 299,753. Redfern, C. G., (Atkins, C. H.). July 29, 1927. Closure members, rotary disc.-In means for draining rotary steam chambers, a stationary single-ported hollow disc valve 1 successively opens passages 13 in a housing 3 attached to the end of the rotary drum 4, the passages communicating with pipes 16 in the drum through which the condensate is ejected by the steam pressure. The valve is held to its seat by steam pressure admitted from the drum through an opening 20, and the condensate passes through its hollow interior to a waste pipe 11. Fig. 5 shows a modified form of valve, which is pressed on to its seating upon a plate 14 by a spring 23.

Abstract: 1426874 Welding by pressure MULLARD Ltd 4 April 1973 [3 May 1972] 20688/72 Heading B3R [Also in Division H1] In sealing an envelope of an electrical component, a metal cover is pressure bonded to a substantially flat metal surface on a wall portion of a base member of the envelope by inserting an intermediate malleable metal layer between the cover and wall portion and applying to the assembly a pressure of 1 to 5 tons per square inch for a period of not more than 30 seconds while maintaining the assembly at a temperature below the melting point of the intermediate layer and below the temperature at which any liquid phase would form between the components. A press comprising a fixed steel base 3, Fig. 1, heated by an electric element 6, and having a support member 9 in which a thermocouple is carried, and an upper movable head 2 comprising a steel pressure plate 21 heated by an element 24, a rubber shock absorber pad 18 sandwiched between an insert 15 on the press head 2 and a support 20 for the plate 21 is used to carry out the bonding. A protective gas, 10% hydrogen in nitrogen is supplied via an aperture 12 in an asbestos cover 8 about the work and the pressure of the plate 12 is increased gradually over 5-10 sees. until the desired pressure is obtained which is maintained for the desired time. Lead in conductors 32 of Kovar (Registered Trade Mark) extend from an outer frame 31 and through an annular glass wall 33 sealed to a Kovar base 35, a Kovar sealing ring 37 being provided on the glass wall 33. All the exposed Kovar parts are gold plated. A silicon wafer 39, gold coated, is pressure bonded to the gold plated surface with an intermediate foil 40 of gold using the press described above, the pressure applied being 2À8 ton per square inch at 300‹ C. for 30 sees. After connections are made between the lead in conductors 32 and pads on the silicon wafer the envelope is sealed. A gold plated Kovar cover 41 is pressed on the Kovar ring 37 with an intermediate gold foil ring 42 at 3À5 ton per square inch for 10 sees. at 300‹ C. Another envelope comprises an alumina base to which a Kovar ring is brazed and lead-in metal conductors are exposed inside the ring and connected to an integrated circuit body mounted on the alumina base. A cover of gold plated Kovar is pressure bonded to the gold plated surface of the Kovar ring via an intermediate soft solder (lead/silver/tin) foil using a pressure of 3À0 tons per square inch for 5-10 sees. at 280‹ C. It is stated that the applied pressure preferably lies between 2 and 3À5 tons per square inch, the intermediate layer may be a coating rather than a foil and may be of aluminium using a temperature of 250-450‹ C. or soft solder consisting of lead/tin, cadmium/tin, lead/indium or lead/ cadmium/tin using a pressure of 2-3 tons per square inch and a temperature of 100-380‹ C.
