Abstract: 745,554. Reciprocating pumps. ELECTROL, Inc. June 4. 1953, No. 15482/53. Class 102(1). [Also in Group XXIX] In a reciprocating pump for supplying pressure liquid selectively to opposite ends of a reversible hydraulic jack, a piston 20, Figs. 1, 2, slidable in a cylinder 19 divides the cylinder into two operating zones. Each zone is provided with a supply port 33 connected to a reservoir 12 and controlled by a check valve 34, a delivery port 37 connected by a passage 38 to a jack cylinder j and controlled by a check valve 41, a by-pass port 47 communicating with the jack cylinder and a return port 51 communicating with the reservoir. The ports 47, 51, are masked by the piston when the piston is in its mid-position. On movement of a hand-lever 26 from its mid-position, e.g., to the right, liquid filling the left-hand zone is expelled therefrom and delivered to the jack cylinder to move its piston to the right and the liquid on the right hand side of the jack piston is returned to the reservoir through the associated by-pass and return ports. On returning the lever 26 to its mid-position, liquid is sucked into the lefthand zone and the liquid from the right-hand end of the jack continues to be expelled until the ports 47, 51, are covered by the piston 20. Continued operation of the lever between its mid and extreme right positions gradually moves the jack piston outwards. Instead of manual operation, the piston 20 may be moved mechanically, e.g., by cams, cranks, &c.

Abstract: 1,075,930. Filter device. ROSAEN FILTER CO. April 13, 1966 [April 14, 1965], No. 16107/66. Heading B1D. A cylindrical filter element 86 is mounted in an outlet aperture 20 of a fluid reservoir 10 and is partly enclosed by an inner housing 92 which provides a chamber 98 for retaining particles separated by element 86, which would otherwise fall back into reservoir 10 when element 86 and housing 92 are removed for cleaning. The filter housing is in three sections, sections 24, 30 remaining attached to the reservoir and cap 44 being removable together with element 86 and housing 92 on rod 56. Attached to rod 56 is a valve member 62 which moves upwards with element 86 under increasing differential pressure acting across annular piston 72, 74, the filter element being by-passed when the piston clears outlet port 42. This movement, indicating clogging of element 86, rotates an external pointer 106 (Fig. 3, not shown). In use, fluid is drawn through element 86 from reservoir 10 by a pump 14 which also removes air trapped downstream of the element, by passages 110, 112 and likewise air upstream of the element, by passages 114, 116, which incorporate a further filter element 118. When element 86 has been replaced, an auxilliary means 120 is used to extract trapped air before restoring normal flow.
