Abstract: 1289690 Electro-plating cellular structures; producing alloy foam; coating foamed resin with metal DUNLOP HOLDINGS Ltd 18 June 1970 [21 June 1969] 31473/69 Headings C7B C7D C7F  A method of producing a porous alloy structure comprises electro-plating a metal on to a conductive porous substrate thereby producing a layer of metal on the substrate, and subsequently alloying the metal by contacting it with an alloying component or a precursor thereof at an elevated temperature in order to introduce by diffusion said alloying component. The electro-plated metal is other than iron (Specification 1263704 is referred to in this respect). The electro-plated metal may be Ni, Cu, Co, Ti, Cr, or Mo. The alloying component may be C, B, Be, Si, N, or Cd, or one of the following metals or an alloy containing such: Cr, Al, Mo, Ti, Zn, W, Fe, V, Mn, Sn, Zr or Cu. The porous structure may be in the form of a skeletal three-dimensional network which defines a plurality of inter-communicating cellular spaces, such as reticulated polyurethane which has been rendered conductive by the application of a conductive surface layer of for example graphite or metal powder. Alternatively the substrate may be made conductive by depositing silver in situ from ammoniacal silver nitrate, in which case the surface should be treated with one or more sensitizing agents such as SnCl 2 /PdCl 2 . The polyurethane foam may have been 33 and 64 pores per inch. The alloying may be effected by: (a) heating the electro-plated structure in contact with powdered alloying component preferably under a reducing atmosphere the powder being optionally diluted with a refractory powder, a carrier compound such as a halide also being optionally present; (b) by contacting the substrate with a gas which may be formed either by passing a gaseous carrier compound, which may be a halide, over the alloying component or a compound thereof or by forming the gas by heating a mixture of the carrier compound and the alloying component or compound thereof. Heating kaolin, alumina or magnesia as a filler with powdered chromium and ammonium fluoride is given as an example of this method; (c) by immersing the substrate in a molten salt bath under an inert gas atmosphere. Molten chromium chloride is given as an example of this latter method.

The pilot valve 36 when unseated serves to vent at 36 a chamber 27 bounded by a flexible diaphragm, 23 secured to a main valve member 24, and apertured at 28 whereby inlet pressure at 19 lifts valve 24 from its seat 22 at times when plunger 61 is at the bottom of its stroke.

Melt 19 is forced by a plunger 17 from the shot chamber into the die cavity. Before the cavity is completely filled with melt, the plunger 17 enters the biscuit-forming chamber. As the melt solidifies in the die cavity 11 pressure is maintained on the plunger 17 to force molten metal into the die cavity from the centre of the biscuit. The pressure is maintained until the melt has solidified in the die cavity. In a further embodiment, the biscuit-forming cavity is formed in both dies and has its widest part at the junction plane of the two dies. In all cases the runner 12 is unrestricted.

In Fig. 3, the opening associated with the low pressure valve plate port has a sharp-edged end 28 at the valve plate face and a streamlined end 29 at the port, providing less flow resistance from the valve plate port to the cylinder port. The opening associated with the high pressure valve plate port has a sharp-edged end at the port and a streamlined end at the valve plate surface, Fig. 4 (not shown). In Fig. 11 the opening associated with the low pressure port comprises a sharp-edged end 42a at the valve plate surface connected tangentially to a chamber 44, and a streamlined end 42b at the valve plate port connected to the centre of the chamber, the swirling motion imported by chamber 44 to liquid flowing from end 42a producing an increased flow resistance. The corresponding opening for the high pressure port has the tangential, sharp-edged end connected to the valve plate port, and the central streamlined end connected to the valve plate surface, Fig. 12 (not shown). In Figs. 5 and 6 (not shown),. the openings each comprise a recess connected to a valve plate port by a groove which is sharpedged at one end and stream-lined at the other. In Figs. 7 and 8 (not shown), the opening comprises a passage formed with a venturi throat adjacent one end, the throat being adjacent the valve plate port end of the passage for the low pressure port, and adjacent the valve plate surface end of the passage for the high pressure port.

An inert bulking agent such as fly ash, wood flour, or foamed polystyrene may additionally be present so that the bolt can be set underwater. A gelling agent such as an alginate, polyvinyl alcohol, polyacrylic acid, carboxy methyl cellulose, or a metallic soap may be added to the water to increase its viscosity so that the method can be used to set a bolt in a ceiling. Freezing or corrosion inhibitors may also be added to the water, particularly if an iron or steel bolt is used. The ratio by volume of particulate material to water is between 1 : 1 and 5 : 1, preferably between 2 : 1 and 4 : 1. The water and particulate material are inserted into the bore in separate capsules which may be made of a brittle material such as unplasticized polystyrene. The capsules may be joined to form a composite container in which case the water capsule may have a flexible plastics wall and be contained within the capsule of particulate material, the latter being made of a water-soluble substance such as polyvinyl alcohol. Alternatively the two capsules in the composite container may be positioned side-byside, the container having a cylindrical shape.
