Title: Improvements in or relating to the Casting of Metal Parts by the Feeding of Liquid Metal into a Mould
IPC: B22D18/04
Filed: 1967-06-16
Abstract: 1,191,694. Casting processes. MICHELIN & CIE (Compagnie Generale des Etablissements Michelin). 16 June, 1967 [24 June, 1966], No. 27963/67. Heading B3F. In the casting of metal articles by pneumaticpressure bottom-pouring from a ladle 19 through a feed tube 24 into a mould, the pressure is maintained, or increased, on the liquid metal while a solidification front travels from one extremity of the article remote from the mould inlet towards the said inlet and the pressure is cut off to allow liquid metal to drop back from the mould inlet when the solidification front reaches the inlet. The mould, at the extremity where the solidification front starts, includes vents that initially allow gas to escape and then become blocked with solidified metal to start the said front. To prevent premature cooling of parts of the article and to ensure the continuous progression of the solidification front, the thickness of the mould walls, which are made of graphite, is varied to influence the rate of cooling and water cooling channels may be provided in a mould core. The mould surface may be covered with a refractory wash of plumbago and the speed in which the solidification front travels in a thin walled article, e.g. a vehicle wheel (Fig. 4, not shown), enables a cast article to be removed from a mould while in a pasty state and before cooling shrinkage makes extraction difficult. Extraction is also assisted by water permeating through the graphite core. The apparatus for casting articles comprises a sealed receptacle 16 containing the ladle 19 and movable on tracks 11 to a position beneath a mould assembly. The mould itself is movable on tracks 31 to a position on either side of a pouring station to enable a pair of moulds to be filled alternately. In operation a mould is brought above the receptacle 19, then a jack 40, via rods 42, lowers a core into engagement with the mould and forces it down against springs 29 to make a sealed engagement between the inlet of the mould and the end of the feed tube 24. After pressure-filling and when the solidification front reaches the inlet, the pressure is cut off, the jack 40 raises the core and the seal is broken and liquid metal falls back down the tube 24. Jacks 46 are provided on the ends of the rods 42 to separate the cast article from the core. The vents may be provided by hollows in mating conical surfaces on the core and mould parts (73), (47), (Fig. 4, not shown) that serve to align the said parts, or they may be provided by a small amount of play in the joints of the mould parts.

Filed: 1945-10-24
Abstract: 622,204. Diaphragm valves. SAUNDERS VALVE CO., Ltd., and PRICE, R. H. Oct. 24, 1945, No. 28077. [Class 135] In a diaphragm valve of the kind in which the diaphragm 6 seats on a weir or partition 3 extending across the valve bore 2 and is clamped between the valve casing 1 and a bonnet 11 housing the valve actuating mechanism, the diaphragm is peripherally confined by the body and at least one of the clamping surfaces is bevelled to form an outwardly divergent space to accommodate a correspondingly sectioned marginal portion of the diaphragm. The clamping pressure forces the diaphragm into sealing contact over its peripheral surface as well as its marginal surfaces and the shape of the marginal part of the diaphragm resists the radial pull due to the fluid pressure. As shown, the diaphragm is accommodated in a recess 8 having a bevelled groove 10 which with the vertical wall of the recess and the chamfered outer edge of a spigot 13 on bonnet 11 forms a space of fish-tail form. Inward movement of the spigot is limited by a flange 12 secured to the casing 1 by studs and nuts 15. The inner edge of the spigot 13 is also chamfered to prevent damage to the diaphragm. The base of the recess 8 is formed by a dished seat 4 provided with ports 5. A screwed operating spindle 18 acts on a diaphragm compressor block 17 through a ball-bearing 24. The diaphragm may be of rubber reinforced by fabric and is moulded so that in the unstressed condition it has the form shown in Fig. 1. For use in low-pressure systems, the diaphragm 6 may be attached to the block 17 by a stud as described in Specification 541,828.
