Abstract: 965,251. Reciprocating pumps. C. HUGHES. Jan. 12, 1962 [Jan. 27, 1961; Feb. 20, 1961], Nos. 3172/61 and 6080/61. Heading F1A. A reciprocating pump for liquids having solids in suspension comprises a liquid chamber formed from a casing having axially flexible side walls. An impulsion member 12 divides the chamber into equal volume inlet and outlet chambers 14, 16 respectively. The member 12 is oscillated by means of eccentrics 32 on a shaft 30 which is driven by an internal combustion engine. The shaft 30 passes between diametrically opposite ports 22 in the member 12. Two, or preferably three sets of valves 26 are provided. The casing comprises rubber or the like rings 38 between which are interposed aluminium or the like I-section rings 40. The casings are assembled under compression and this compression is not completely taken up by the movement of the member 12 to prevent leakage. A flexible cylinder reinforced internally and externally with rigid rings may be used instead of the stack of rings. In an alternative embodiment a second impulsion member oscillating out of phase with the first is provided. In the intermediate chamber so formed there is a fixed ported member carrying a drive shaft for externally mounted eccentrics. Rods fitted to the eccentrics extend to the impulsion members. The inlet, intermediate and outlet chambers are substantially of the same volume. The volumetric change of the intermediate chamber is twice that of the other two on each stroke and as each impulsion member carries a non-return valve the pump is double acting.

Title: A method for ensuring the precision movement of slides, particularly of machine tools
IPC: B23Q16/00
Filed: 1953-02-13
Abstract: 724,415. Machine-tool details. SCHBERT, W. Feb. 13, 1953 [Sept. 12, 1952; Dec. 1, 1952], No. 4124/53. Class 83 (3). A method for setting a slide 1 in a machine tool consists in positioning, between the bed and the slide, end gauges 5 which are longer than their nominal length by an amount equal to that by which they are compressed when the slide is clamped in position. The slide 1 preferably carries the tool and is associated with a fixed hydraulic feeding piston 3. End gauges 5 for a series of operations are carried on a slide 4 which is moved transversely between the operations. The fluid is supplied, at a pressure indicated on a dial 23, by a pump 11. As the slide reaches its final position, a valve 7a, 7b gradually cuts off the pressure and opens an exhaust line 18 so that the slide comes to rest without exerting any pressure on the gauge bar 5. Furthermore, towards the end of its movement, the valve actuates a switch 20 which de-energizes an electromagnet 21 to open a valve 22 and supply fluid again to the piston 3. The slide then pushes the end gauge 5 and the valve rod against an abutment 9, the fluid being progressively throttled by the valve 7a. The slide is clamped in position by mechanical and/or hydraulic means and the pump 11 stopped. The slide is moved in reverse by operation of a valve 16. A valve 24 then opens automatically to enable the slide to travel at a fast rate. The hydraulic system may be modified to include a hydraulically-operated plunger 33 bearing rackteeth meshing with a gear 35 which clamps the slide in adjusted position through a plate 36. The plunger 33 may be carried on the slide or the bed.
