Abstract: 842,468. Stereotype casting apparatus. FUNDITOR Ltd., and SPITTLE, W. R. April 10, 1958 [Aug. 13, 1957], No. 25549/57. Class 100(2) In a stereotype casting machine of type comprising two separable platens 6, 7 between which the type metal is cast when the platens are in a near vertical position, the platen 6 is fixed and the platen 7 is supported by means which enable it to be moved between a near vertical operative position and a horizontal position. The fixed platen 6 is attached to a frame 9 above which is disposed a melting pot 2. The platen 7 is pivoted at 10 to a member 11 provided with rollers 12 which slide along a horizontal or slightly inclined track 13. Also pivoted to the platen 7 is one end of an arm 17 the other end of which is connected by a lost-motion pin and slot connection to fixed frame member 21. The pivot 10 is arranged slightly above the centre of gravity of the platen 7 and a handle 24 is provided on the member 11. A clamp 26 is provided for securing the two platens together. After casting the clamp 26 is released and the handle 24 drawn rearwardly. For the first part of the movement the platen 7 moves parallel to the platen until the lost motion in the connection between the arm 17 and frame member 21 is taken up. Thereafter the arm 17 acts to pivot the platen 7 about the pivot 10 into a horizontal position against a stop 23. A retaining spring- loaded catch 25 is provided. Return movement is effected by the handle 24 and swinging of the platen 7 is assisted by gravity, and also, if desired, by providing a track 13 slightly inclined downwards towards the platen 6, until the platen engages a stop 22.

Abstract: 915,350. Purifying exhaust. OXY-CATALYST Inc. July 14, 1961, No. 25596/61. Class 7(2) [Also in Group XXVIII] An exhaust gas purifier for use with a spark ignition reciprocating I.C. engine adapted to operate on leaded gasoline fuel comprises a air inspirator 3, Fig. 1, a purifier housing 1 containing a bed of randomly distributed catalyst pellets P, the housing having guide means to lead the exhaust gas and air mixture through the bed which has a flow cross-section in the range of 1,500 to 32,000 square inches per pound per minute of fuel consumed by the engine when the minimum total energy of the mixture is entering the bed, the bed thickness being approximately uniformly 0À3 to 3 inches and the catalyst pellets providing a surface area in the range of 115 to 250 square inches per cubic inch of piston displacement. Exhaust gases passing through pipe 2, draw in ambient air through pipe 10 from filter 11 into chamber 9. The resultant mixture passes in the direction of arrows through the catalyst bed which is held between perforated grids 25, 26, Fig. 2, e.g. of stainless steel, mounted to permit thermal expansion. The housing 1, e.g. of stainless steel or aluminized steel, has thermal insulation 1a and a metal covering 1b. The geometric shape of the catalyst bed may be flat or annular in the sense of confinement between concentric cylindrical or conical entrance and exit surfaces, the radial cross-section of which may be circular, elliptical, oval or polygonal with radial inward or outward gas flow. Alternatively the bed may be confined between concentric spherical segments. Catalysts in cylindrical pelleted form may comprise a carrier of activated metal oxide, e.g. beryllia, thoria, magnesia, zincite, zirconia, alumina impregnated with metals or metal oxides such as platinum, palladium, rutherium, rhodium, copper, silver, chromium, vanadium, manganese, iron or mixtures of copper and chromium oxides.

In one embodiment, a ring 10 is bored to receive three rollers 26 which are mounted on a journal 25, Figs. 3 and 4, of a member 14 which is adapted for radial adjustment in the ring 10, projections 15 sliding in a radial slot 13 in the ring. An eccentric pin 20 engages in a slot 16 in the member 14 and the radial adjustments are made by rotating the member 19 (which may be graduated) and clamping it in position with screws 21 passing through slots 22 and engaging in threaded holes 24. The axial staggering of the grooves on the rollers to follow the helix of the thread may be obtained by inserting. shims, by varying the thickness of the members 14, or by positioning the grooves on the rollers to suit the rollers concerned. In another embodiment, Fig. (i, six rollers 34 are arranged round the face of the frame 30. Oil grooves 38 are provided.
