Title: Process and Apparatus for Melting Metals While Reducing Losses Due to Oxidation
Inventor: GESING ADAM J
IPC: C25C3/00
Filed: 1992-07-10
Abstract: A process and apparatus for melting metals while reducing losses due to oxidation.  The process involves melting the metal in the presence of a molten metal salt electrolyte while electrolyzing metal oxide contained in the salt electrolyte to convert the oxide to elemental metal.  The process requires an electrolyte which contains at least 25% by weight, and more preferably 100% by weight, of metal fluoride and which, for the metal being melted, has a composition which remains substantially unchanged during the electrolysis process. The fluoride improves oxide solubility in the electrolyte, making it possible to increase current densities without producing anode effects.  The stable composition makes it possible to use the electrolyte for prolonged periods without change.  The apparatus consists of a single vessel having an interior volume divided at least into a melting zone and an electrolysis zone by a heat-resistant partition which allows the electrolyte to be recirculated between those zones.

Abstract: The present invention relates to a novel process for forming thin metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltrating atmosphere are in communication with a filler material or preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the application of any pressure or vacuum. In an embodiment of the present invention, the filler material may be sprayed upon a thin sheet of matrix metal. Alternatively, the filler material may be shaped via tape casing, slip casting, etc.  to provide a thin preform. In another embodiment of the present invention, a body of matrix metal may be coated with a filler material such that upon spontaneous infiltration a metal matrix composite body is produced which inversely replicates the configuration of the original body of matrix metal.

Title: Air separation
Inventor: RATHBONE THOMAS
IPC: F02C6/10
Filed: 1993-04-13
Abstract: ABSTRACT AIR SEPARATION        Air is compressed in a compressor 4.  A minor stream of the compressed air is cooled first in heat exchanger 12 by a pressurised stream of moisturised nitrogen and then in heat exchanger 14 by a stream of pressurised water, the stream of pressurised water thereby being heated. The cooled air is separated into oxygen and nitrogen in an air separation plant 16.  The oxygen product is passed to a blast furnace 22 in which iron ore is reduced to iron and a low grade fuel gas is produced.  The fuel gas flows to a combustion chamber 6 in which it is burnt using the rest of the compressed air to support its combustion.  The resulting combustion gases are expanded in a turbine 8 which is used in the generation of electrical power.  The nitrogen product of air separation is moisturised in gas-liquid contact column 28 with the heated stream of pressurised water.  The resulting moisturised stream of nitrogen is that used in the heat exchanger 12.  It passes out of the heat exchanger 12 and is expanded in expansion turbine 32 which is used in the generation of electrical power.

Abstract: A method and system to immediately connect and reswitch connection configurations through a rearrangeable communications matrix that immediately connects an input gate causing rearrangeably blocked condition through the communications matrix to an output gate through a dedicated or extra switching element of the center. With the rearrangeably blocked condition, the method and system select a set of switching elements pairs from the center stage switches to form a plurality of possible connections from the input gates to the output gates that excludes the dedicated switching element. The method and system then determines from the possible connections a minimum rearrangement connection configuration that excludes the dedicated switch and that requires the minimum number of rearrangements of existing communications matrix connections. Then, the invention reswitches the matrix according to the minimum rearrangement connection configuration while maintaining all signal flow from the input gates to the output gates while removing connections through the dedicated switching element. The preferred embodiment has particular application for digital cross-connect networks that include a time domain and a space domain for connection configurations where rearrangeably blocked condition may occur in either domain.

Inventor: AU CLARENCE P
IPC: E04G17/065
Filed: 1993-11-30
Abstract: The present invention relates to concrete forming structures and in particular to concrete wall forming structures and further to strongback members used to support, at a rear edge of a wall form, the concrete wall forming structure.  The strongback provides horizontal support to exterior upright structural members and the strongbacks include cooperating tie plates associates with tie bars which typically pass through the concrete material.  Preferably, the strongback is an extruded member of a channel-like cross section defined by a base with opposed flanges extending from the opposite ends of the base and to one side thereof.  One of the flanges includes a slot arrangement which cooperates to engage to a tie plate which can be initially supported from the strongback. The tie plate will then pass through a tie bar and an appropriate mechanical arrangement will allow tensioning of the tie bar.  In one embodiment, the opposite flange from the one flange which cooperates with the tie plate is adapted to have a drop in wedge shape for cooperating with an upwardly opening bracket attached to an upright member. In this way, the strong back is easily supported from the wall form structure and conveniently supports, in an operative position, the tie plate in preparation for securing of the tie plate and also engages one end of the tie plate when a tensioning load is applied to the strongback.  A modified tie plate for high load applications is also disclosed which cooperates and engages the slot provided in the flange of the strongback and overlies this flange and overlies the base member and is adapted to contact an upright member adjacent the point of contact of the strongback with an upright member.  Thus, the tie plate is adapted to directly transmit some forces exerted thereon to an upright support member as well as through the strong back.
