Title: Improvements in ball piston type fluid engines
Inventor: AVERY HOWARD WILLIAM
IPC: F04B53/16
Filed: 1955-09-07
Abstract: 816,604. Cylinders; pistons. GENERAL ELECTRIC CO. Sept. 7, 1955, No. 25654/55. Class 122 (1). [Also in Group XXIX] The cylinder 7 of a pump, motor, clutch or other fluid engine employing a ball piston 9 which is reciprocated by the relative movement of the cylinder block 1 and a cam track 10 disposed at one end of the cylinder is fitted with a liner 8 having a clearance fit with the cylinder bore and mounted so as to have free lateral movement within the limit imposed by its clearance fit; a limited flattening of the liner and increase of the clearance between the ball and liner at the polar areas of the ball at the ends of its axis of rotation are therefore permitted. As applied to a pump, the cylinder block 1, provided with a number of radial bores 7, is mounted in a housing 4 for rotation on a pintle 2, and the eccentric inner surface of a cam ring 10 surrounds the block for co-operation with the balls 9 in the bores. Oil is admitted to the inlet ends of the bores 7 through an inlet 11 and cavity 12 extending over part of the surface of the pintle 2 and discharged from the bores through a second surface cavity 14 of the pintle and outlet 15. Each liner 8 has a bevelled inner end 20, Fig. 2, engaging a silicone rubber packing 21 in a groove in the wall of the bore, and is held in the bore by a split ring 17 engaging co-operating grooves 18, 19 in the liner and bore and spring-biased into contact with the bottom surface of the groove 18. A wire 23 in the groove 19 retains the ring 17 in position, and an aperture provided in the cylinder block opposite each groove 19 permits the insertion of a tool for separating the ends of the ring to facilitate its removal. The balls and liners may be made of cemented carbide and each liner and its ball are arranged to have the same heat storage capacity. The cam track 10, instead of being fixed, may be mounted for rotation with the cylinder block or instead of it. The invention is also applicable to arrangements in which the axes of the cylinders are parallel to the axes of rotation of the cylinder block and a cam track is located at one or both ends of the cylinders. When the fluid engine is used as a clutch, rotation of one of the relatively-rotatable parts of the engine can be made to transmit its rotation to the other part depending upon the amount of restriction provided in an interconnection between the inlet and outlet ports of the engine.

Patent GB-741700-A (GB)
Title: Improvements relating to devices for inserting photographic film into position for exposure in cameras having curved image surfaces, and for discharging the exposed filmtherefrom
IPC: G03B17/17
Filed: 1953-09-18
Abstract: 741,700. Photographic cameras; film-feeding mechanism. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE OUDE DELFT. Sept. 18, 1953 [Sept. 19, 1952], No. 25825/53. Classes 97 (1) and 98 (1). Photographic film is inserted into and removed from the exposure gate of a camera having a curved image surface by leading a strip of the unexposed film from a supply spool outside the exposure field so far into the exposure field that the leading part of the strip covers the image surface, cutting off the said part of the strip and pressing it to conform with the contour of the image surface for exposure, and releasing it after the exposure. As shown, on each revolution of the motor-driven shaft 18, the diagonal channel of a drunken screw 16 engaging rollers 14 on a gear disc 12 drives this disc and hence a feed roller 5 geared to it and co-operating with an idler roller 4 to feed between them a film strip 3 which passes down a light-tight guide to the doubly concave image surface of the concave mirror objective defined by the exposure gate frame 9. When the leading end of the film covers the gate, the feed stops due to the engaged roller 14 entering the straight portion 15 of the feed screw and a cam 19 on the shaft 18 causes through arms 20, 22 on a lay shaft 21 the convex presser plate to force the film against the concave gate frame, a guillotine formed between the edges 25, 25a on the presser plate and gate cutting the film. After exposure, continued rotation of the shaft 18 causes the presser plate to be withdrawn, whereupon the cut film falls between edge guides into a stack in a storage chamber 27. In order to dispense with the portion of the light-tight guide which obstructs part of the objective, the feed mechanism may be caused to withdraw the strip after severing of the portion to be exposed by suitable design of the drunken screw. In a modification, the lower edge of the presser plate is recessed to accommodate a pair of rods vertically reciprocated by motion derived from one of the rollers 4, 5 of the film feed mechanism and each bearing a pin which is pressed through a lower corner of the film into a hole in the gate frame by clamping movement of the presser plate. On releasing the presser plate the film remains on the pins and is carried down into a removable storage chamber where it is removed from the pins by an inclined deflecting plate through which the rods pass.

Abstract: 780,370. Tufting machines. CARD, J. L. Sept. 9, 1955 [May 16, 1955], No. 25894/55. Class 112 A multineedle machine for making a loop pile fabric having a pattern repeated across the width of the fabric comprises a plurality of "repeat" needle groups arranged in end to end relation transversely to the direction of the fabric feed, a plurality of yarn feed means proportionate in number to the number of needles in each group, each feed means receiving a number of strands which is a multiple of the number of groups, and guides associated with each feed means for receiving the yarns and delivering them to the selected needles. The feed is effected by a number of rollers extending forwardly from the machine perpendicular to the plane of the needles. Each roller may be clutched to a high or low speed drive resulting in long or short loops respectively being formed on the fabric. Electromagnetic clutches are employed, their energization being controlled by a pattern control member rotated in synchronism with the machine. The yarns may all be of one colour, the pattern being formed by the contrast between the length of loops. Alternatively, alternate needles of a group may be fed with different coloured yarns and may form long and short loops respectively, the former concealing the latter. A pattern may thus be formed with contrasting colours. The machine shown in Figs. 1 and 3 employs a thousand needles 12 mounted in a bar 11 driven by eccentrics 7 mounted on a drive shaft 5. The needles are divided into ten groups of a hundred needles, each group forming a pattern. There are fifty feed rollers 31 each carrying twenty threads and supplying two adjacent threads to each group of needles. Each roller is faced with emery cloth and the fabric 16 is fed across the needle plate 13 by spiked feed rolls 17. Each thread passes througn a metal or plastic guide tube 52, the upper ends of the guide tubes associated with each roller being secured to panels 53; the lower ends are secured to a panel 56. The rollers 31 are driven by chain and sprocket high and low speed gearing arranged in casings 19 the rollers being clutched to the high or low speed drive by clutches 34, 33, Fig. 7, controlled by relays 69 coupled between a current source and contact fingers 66 co-operating with an earthed rotating drum carrying an insulating sleeve 64 with cut out portions 65 defining the pattern. There is one finger 66 for each feed roller. Specifications 735,019 and 778,471 are referred to.
