Abstract: A molten metal holding and pouring box with a rectangular-shaped upper section and a pyramidal-shaped lower section provides a relatively constant flow of molten metal being poured from the box through each of two bottom nozzles into two separate foundry molds at the same time. The two bottom nozzles are contained in a unitary dual nozzle assembly that facilitates replacement as required by wear, or a change in location of the sprue cups in the two separate foundry molds being filled with molten metal.

Abstract: A voucher processor (122) receives (204) a plurality of voucher identifiers from a voucher provider (132) and, for each voucher identifier, instructs (208) the issuing of payment credentials of a payment instrument from an issuer processor (123). The issuer processor (123) or the voucher processor (122) links (210) each voucher identifier to payment credentials of a corresponding payment instrument. The voucher processor (122) or issuer processor (123) submits the plurality of voucher identifiers to the voucher provider (132) along with the linked payment credentials for each voucher identifier, such that, subsequent to a voucher being activated (408), the voucher provider is capable of initiating (424) a transfer of funds associated with the voucher in favour of the voucher provider (132) by transmitting the payment credentials linked to the voucher identifier for receipt by the issuer processor (123).

Abstract: A method of treating pain by the co-administration of an antidepressant together with one or more precursors or inducers of neurotransmitters, particularly amino acids selected from L-phenylalanine, L-tyrosine, L-tryptophan and L-DOPA.

Abstract: A process is described of forming a diffusion bonded article from components made of aluminum or an alloy thereof that forms a protective coating of an oxide that inhibits such bonding. The process comprises removing the oxide layer and immediately forming the components into a stack, placing the stack in the chamber of an electron beam welding device, evacuating the chamber and electron beam welding the edge regions of the stack; the welded stack can then be diffusion bonded at leisure without the oxide re-forming. The diffusion bonded article can be superplastically formed to a finished or semi-finished shape.

Abstract: In a superplastic forming/diffusion bonding process, in particular for aluminum-lithium alloys, the stop-off material in the diffusion bonding step is a porous lamellar material such as glass cloth or vermiculite paper. In one embodiment, prior to diffusion bonding, the stack of alloy sheets and lamellar material may be sealed under vacuum.

Abstract: A method is described of diffusion bonding and superplastic forming components made of aluminium or an aluminium alloy to form a composite formed article. The method involves applying stopping-off material to selected areas of the components to prevent diffusion bonding in those areas, the stopping-off material being applied by plasma spraying.

Abstract: The present invention provides a process in which components made of aluminum or an alloy thereof can be diffusion bonded together; the process involves chemically treating the components to remove aluminum oxide on the surface of the components, subjecting them to grit blasting and to a second chemical oxide removal step and finally pressing the components together under heat until they form diffusion bonds. The resulting composite can be superplastically formed to shape.
