Abstract: 1,250,791. Reciprocating motors. BUTTERWORTH HYDRAULIC DEVELOPMENTS Ltd. Jan.28, 1969 [Feb.12, 1968], No.6798/68. Headings F1A, F1M and F1P In a fluid actuated motor the centre of oscillation of the piston may be axially adjusted. As shown, a valve piston reciprocates in a sleeve 7 axially slidable in a housing 3, and the exhaust and supply of pressure fluid to motor chambers 5, 6 is controlled by a spool valve 13, exhaust passing from cylinder 2 to a port 48 via passage 37, transfer chamber 26, passage 41 and port 46, and then to exhaust passage 29 by way of passage 52 and transfer chamber 25. Piston travel in the direction X is terminated by port 48 being closed by a land 11. Reversal of spool valve 13 by admitting pressure fluid to alternating pressure chamber 19 causes piston 1 to move in the direction Y as chambers 5, 6 communicate with pressure fluid and exhaust respectively, until land 10 closes either ports 47, 47a or 47b communicating via a port selection device 59 with exhaust passage 29, by which means the piston stroke can be varied. The sleeve is prevented from axial movement by pressure fluid acting through a recess 67 controlled by a pressure/exhaust valve 69. To alter the centre of oscillation supply and exhaust passages are disconnected from the spool valve and connected to a selector valve 78 alternately supplying and exahusting pressure fluid from motor chambers 5, 6. With the piston moving in the direction X valve 69 is adjusted to open recess 67 to exhaust to allow sleeve 7 to slide within the housing 3. Land 11 abuts a peg 12 on the sleeve shortly after closing port 48 to move the sleeve in the direction X. When the desired positioning is reached passages 37, 38 are reconnected to the spool valve and valve 69 is adjusted to reopen recess 67 to pressure fluid to prevent axial movement of the sleeve. In alternative constructions the piston may be continuously reciprocated and means provided to reciprocate the piston and spool in phase.

[Also in Division C3] Ferrous metals are cast into granular refractory moulds and/or around granular refractory cores having coatings of a composition comprising zinc, strontium or cadmium, or compounds of these elements and a carbonaceous material. The coating melts, vaporizes, or decomposes at the temperature of the cast metal and inhibits dendritic growth from the walls of the mould or core so that nucleation takes place on impurities throughout the cast metal to give a fine dendritic crystal structure. In the example, iron is cast at 1480‹ C. into greensand moulds coated with a suspension of zinc (80% wt., 200 B.S.S. mesh) and coke (20% wt. 100-200 B.S.S. mesh) in isopropyl alcohol. The Specification mentions the following methods of producing coated moulds or cores: (a) applying the coating composition to the surface of a pattern, preparing the mould or core from the pattern, stripping the mould or core from the pattern thereby transferring the coating composition from the pattern to the mould or core; (b) dusting a powdered composition on to the moulds or cores; (c) spraying a suspension of the composition in an aqueous or organic liquid (e.g. alcohols) on to the moulds or cores, followed by removing of the liquid (by stoving for water, by burning off for alcohols); (d) dipping the mould or core with a suspension of the composition; and (e) painting the mould or core with a suspension of the composition.
