Title: Method of making and elastomeric container
IPC: B29C41/00
Filed: 1973-07-10
Abstract: 1422828 Moulding elastomeric containers GOODYEAR TIRE & RUBBER CO 10 July 1973 [11 Aug 1972] 32735/73 Heading B5A In a method of building a container having an access opening, e.g. a fuel cell, a destructible form is coated with a plastics film to form a flexible envelope thereon, a layer of release agent applied to the film, and an elastomeric container is built up on the thus coated form; the form is then destroyed and removed from the container by pulling the flexible envelope, containing the destroyed form, out through the access opening in the container. The method ensures that the inside of the container is clean and free from scaps of form material. In one example, a cardboard form with a flexible polyurethane envelope thereon is coated with polyethylene as a release agent and then used to form a polyurethane container by spraying. Successive layers of polyurethane, nylon (to form an impervious barrier layer) polyurethane, fabric reinforcement, and finally polyurethane are applied, the container cured, and the form destroyed by first soaking in water and then breaking up by blows from a rubber mallet. The envelope containing the fragments of form material was then removed from the container. In a second example, a plaster of Paris form is provided with a polyurethane envelope and a release coat of sugar and water and then used to produce a fuel cell by laying up of acrylonitrile butadiene rubber calendered nylon fabric, a sealing layer of natural rubber being provided between two of the layers. The form is broken up as in the first example and then removed. In addition to polyurethane, the flexible envelope may be of p.v.c. or rubber, and the barrier layer may be polyvinylidene chloride.

Title: Improvements in or relating to welding
Inventor: COOKSEY ROBERT JAMES
IPC: B23K35/34
Filed: 1959-07-06
Abstract: Welds are effected and heat treated by bringing such metal parts as nickel or its alloys, but particularly sections of iron or steel piping in proximity at the surfaces which are to be welded, placing blocks of an exothermic composition on the metal parts near these surfaces, firing the composition to preheat the parts, thereafter effecting the weld and allowing the fired composition blocks to cool in situ, thereby heating the weld and adjacent heat-affected areas to a temperature, e.g. at least 600 DEG  C. for low alloy steel to at least 900 DEG  C. for alloy steel containing 5% Cr and 0.5% Mo, from which they cool slowly, thus annealing and stress-relieving the weld. Preferably, the blocks may be moved, after welding, towards one another to cover the point of the weld.  The composition contains finely divided aluminium, an oxidizing agent in insufficient quantity to completely oxidize all the aluminium, e.g. MnO2 and/or Fe2O3 with or without sodium or potassium nitrate or chlorate, and a heat-insulating filler, e.g. granulated grog, alumina or furnace aggregate, with not more than 5% by weight of siliceous material; a fluoride, e.g. cryolite, binder such as bentonite, core gum or sulphite lye, with or without a cement additive, e.g. gypsum plaster, may also be added to the composition.  The blocks may be formed in situ by applying the composition in the form of a paste and drying or a plurality of contiguous blocks carried on a flexible support may be used.  The blocks may be fluted or corrugated to reduce contact with the metal and/or backed with a heat-insulating material such as grog, asbestos or suitable admixture (see Group V) and so fabricated to allow access of air.  Specifications 568,453 and 819,077 also are referred to.ALSO:A heat-insulating material, suitable for backing an exothermic composition (see Group II) block used in the welding of metal parts (see Group XXII), has the composition by weight: furnace aggregate 55 parts, paper pulp and wood chippings 40 parts; asbestos fibre 5 parts, whole being bound with gum arabic or sulphite lye. Specifications 568,453 and 819,077 also are referred to.

'Class 20(ii) In an adjustable metal pit prop comprising an upper member 2 of cruciform shape in cross-section, slidable in a lower member 1 and secured by clamping means in a locking hoop 4, the clamping is effected by the inward displacement of wedges 5, 6 by means of a straining. member 9 and by the clamping action, not in the line of that inward displacement, of wedges 7, 8 provided with inclined faces co-operating with inclined abutments in the locking loop whereby the straining action forces them inwards. The wedge 5 is divided to form a pair of opposed wedges which are forced into clamping position by the straining member 9, which is in the form of a transverse wedge. The opposite wedge 6 has interposed between it and the locking loop 4 a wedge 10 whereby adjustment may be made for manufacturing inaccuracies. The wedge 10 may be welded in place after the adjustment has been made. The wedges 5, 6 strain the locking loop and the strain is resisted by the wedges 7, 8 which are therefore forced inwards, the faces of these abutments 43, 44 making a non-self locking wedge angle with one another. Deformation of the locking loop may be facilitated by slots in the base plate 3 which supports it, or by making the plate 3 resilient. In the modification shown in Fig. 3 a wedge 12 has an inclined face which bears against two straining wedges 17 which in turn bear against inclined faces on the locking hoop, and against a transverse wedge 18. The wedge 18 is frictionally self-locking whereas the faces bearing against the wedges 17 do not form a selflocking wedge angle.
