Abstract: 1294854 Casting composition pistons; forging; making pistons ASSOCIATED ENG Ltd 21 Jan 1970 [31 Oct 1968] 51755/68 Headings B3A B3F and B3H A method of making a piston, consisting of a reinforcing member having at least a surface portion formed of a metal or metal alloy and a contiguous cast metal part joined to said surface portion, includes the steps of coating the surface portion with a low-melting-point alloy, and casting a melt of a metal or alloy of the same alloy system as the surface portion, i.e. having the same metal as its major constituent, on to the coated surface. When aluminium or its alloys are being cast suitable low-melting- point alloys are tin-zinc eutectic or aluminiumsilicon eutectic alloys, and when ferrous or copper alloys are cast, the low melting point alloy may be a ferrous or copper alloy respectively. The reinforcing member is reinforced with wires, fibres or whiskers and in an embodiment is prepared by plasma spraying aluminium on to an array of stainless steel wires wound on a mandrel 1; a further layer of wire is then wound on and the process repeated until a metal member of the required size has been built up. It is then slit along each side and cut into pieces which are hot-pressed at a temperature of 500‹ C. and under a load of 25 tons for one hour. The pieces are then dipped into a tin-zinc alloy at 300‹ C., abraded with steel wool, the process repeated several times and the pieces given a final immersion in the alloy. They are then located on a sand core in a die and an aluminium-silicon alloy poured in. Before pouring, the die is heated to about 375‹ C. and sprayed with a suspension of talc in sodium silicate and water so as to give a rough surface coating. A ferrous reinforcing member may be reinforced with tungsten or molybdenum wire or carbon fibre.

Abstract: 1335094 Rotary drum filters VOGELBUSCH GmbH 19 April 1971 [13 Feb 1970 13 Jan 1971] 21515/71 Heading BID In the operation of a rotating filter drum 1, the interior of which is not subdivided, the transfer of suspension-to-be-filtered to the drum from trough 7 is interrupted, during one or more revolutions of the drum, by the automatic lowering of the trough by the action of pneumatic cylinder 9. The suspension is supplied to trough 7 via conduit 30. The perforated drum is covered with filter cloth 2, e.g. of stainless steel, and this has a coating of filter aid 3, e.g. powdered starch. The thickness of the layer 5 of suspension on filter cake 4 is controlled by blade 25. The filtrate, sucked into the drum, is withdrawn therefrom through suction conduit 6. The trough 7 is lowered after the filter cake has reached a predetermined thickness. After trough 7 has been lowered, blade 22 is actuated by pneumatic cylinder 24 so as to wipe excess suspension from the filter cake. After the cake has been sucked dry, washing liquid (e.g. water) is sprayed onto it from nozzles 27; the cake is then sucked dry again. The cake is now removed from the drum by knife 10 which is actuated by pneumatic cylinder 12. Knife 10 is then moved a minute amount, by rotation of latch wheel 16 actuated by pneumatic cylinder 18, so that a thin layer of filter aid 3 is removed from the drum. The trough 7 is then raised, and the cycle of stages is repeated. The time intervals of the various stages may be controlled according to the nature of the suspension being filtered. Hydraulic cylinders may be used instead of pneumatic cylinders. The knife 10 is automatically sharpened by a scraper 43 (Figs. 8, 9, 10, not shown). The filtration of brewery and wine-fermentation sediments is referred to; also the filtration of autolysed cream of yeast.

Filed: 1999-10-12
Abstract: A novel and improved method for performing paging is described. In one embodiment of the invention a searcher is used to detect spread spectrum signals. Samples received RF signals are stored in a sample buffer. During standby mode, the samples are gathered during paging slots assigned to the mobile. A set of searches are performed on the samples, and if pilot signals are detected additional demodulation is performed to detect paging messages. The resulting set of demodulation data may be combined to increase detection. After a page message has been detected, additional demodulation resources may be activated to processes more complete page messages, or other information channels. In one embodiment of the invention, the searcher includes a demodulator to perform quick page detection without the use of finger elements to reduce idle mode power consumption.

Title: Method of brazing metal surfaces
IPC: B23K35/22
Filed: 1992-01-24
Abstract: A novel method is described for joining aluminum to metal surfaces by brazing. The method comprises (a) applying as a coating to at least one of the metal surfaces to be joined a mixture of a metal (e.g. Si, Cu or Ge) and a brazing flux, the metal of the mixture being adapted to form a brazable eutectic with one or both of the surface metals, (b) heating the surfaces and the coating in juxtaposed relation to a temperature above the brazing alloy melting point to thereby dissolve oxide film on the surfaces to be joined, cause the metal of the coating to dissolve into the oxide-free aluminum surface and form therewith a brazing alloy layer and form a brazed assembly and (c) cooling the brazed assembly to form a solidified joint between the surfaces. This has the advantage of providing for the joining of metal surfaces, such as aluminum, to aluminium, cooper, brass or steel surfaces, by brazing without the prior formation of a brazing alloy cladding on the surfaces to be brazed.
