Filed: 1935-12-17
Abstract: 456,946. Revolving-cylinder pumps. SAUSSARD, L., and SAUSSARD, A., 4, Rue de Varize, Paris. Dec. 17, 1935, No. 34977. Convention date, Dec. 18, 1934. [Class 102 (i)] A pump, of the type in which a rotating drum 2, Figs. 1 and 3, contains two frames 7, 8, which reciprocate at right-angles to one another and are mounted on a pivot 9a eccentric to the driving shaft, is characterized in that one or both of the distribution passages 9g, 9h passes through the eccentric pivot. As shown the pivot 9a has a spherical end on which the frame 8 is mounted, and the stroke of the pistons is varied by rocking the pivot 9a about trunnions 10, 11 by means of an eccentric 14, which is encircled by a frame 13 sliding in guides 9d in the pivot 9a. The passage 9g communicates with the interior 1a of the casing and with a pipe 1b, while the passage 9h communicates with the hollow trunnion 11 and with a passage 1c. A byepass valve 17 can be operated by turning a sleeve 18. The frames 7, 8 and a block 6 secured in the drum 2 by screws 20 are all formed in halves. The pistons 7a, 8a are surrounded by rings 7d, 8c which secure the halves of the frames, and the frame 8 is further secured by rings 8d, 8e. The guiding slides 6b, 6c, 7f are formed cylindrical. In a modification the end of the pivot 9a is cylindrical, and in this case the cylinders assume an inclined position when the pin 9a is eccentric to the driving shaft. In another modification the pivot 9a contains only one of the distribution passages, the other being formed between the periphery of the drum 2 and the interior of the casing 1. In the modification shown in Fig. 8, the pivot 9<1> is carried by a slide 9p and is moved transversely to the driving shaft 3<1> by means of a screw 25a. The slide 9p moves between a wall lp in the casing 1<1> and a block 23 secured by a cover 22. The distribution passages are formed in the pivot 9<1> and in the block 23. Specification 438,517 is referred to.

Title: Improvements relating to the production of straw or like envelopes for bottles and the like, and/or to the production of straw or like packing mats
IPC: B65B21/24
Filed: 1946-11-26
Abstract: 619,200. Sewing-machines. JARDINE, R. Nov. 26, 1946, No. 35093. [Class 112] Straw and like materials, stitching.-A machine for stitching straw or the like into mats or bottle wrappers is arranged so that its operation is continuous, successive articles being connected by a chain of stitches which is automatically cut, and the need for stopping after finishing each article being eliminated ; a wrapper is formed by folding over a mat as it is formed and connecting its two ends by the stitching, thus avoiding the usual overlap and dispensing with the usual cylinder around which a wrapper is usually formed and from which it has to be stripped laterally. The machine shown comprises a series of spiked chains 6, by which the straw is fed over a set of latched hook needles 48 co-operating with individual threads carried by a laterally-reciprocating shuttle-bar 55 to form chain-stitch seams, a set of longitudinal strips 10 to hold the straw on the chains during stitching, a laterally-extending plate 11 over which a mat may be folded to produce a wrapper, cam-operated arms 32 with feet 33 by which the folded-over mat is positioned for the connection of its ends, and cam-operated bars 42 carrying knife blades 43 for severing the chains of threads between successive articles and blades 46 shaped to guide the mat back over the plate 11 and serving to sever any displaced straws between articles. Cam-actuated members 39 are provided to hold the 'threads in position to be engaged by the needles in spite of the rearward movement of the upper part of the mat when wrappers are being formed. The spacing of the spikes on the feed-chains may be increased at intervals, the wider spaces being left empty of straw ; the amount of straw required for the wrapper is thus readily determined. For producing flat mats, the knife-operating cam is formed so as to raise the knives 43, 46 again immediately after their cutting stroke ; in the formation of wrappers the knife bars 42 remain down until the mat is turned back over the plate 11 and engaged by the feet 33.

Abstract: 1,070,446. Air cushion vehicles. WESTLAND AIRCRAFT Ltd. Aug. 26, 1965 [Sept. 3, 1964], No. 36053/64. Heading B7K. An air-cushion vehicle comprises a base structure 1 and an air duct 3 leading to a plurality of contiguous concertina-shaped tubular elements 2 each terminating at its lower end in a pressure sensing and curtain-forming unit, wherein curtain and cushion-forming air issues from nozzles 5 and 6 and individual cushions are formed between the ground surface 7 and diaphragms 14, 15. The elements 2 are connected on their inner and outer sides by diaphragms whereby a continuous flexible skirt is formed to enclose the main cushion 8. The elements 2 are free to extend and contract and are restrained in substantially vertical positions by elastic ties 21-24 which, when the elements 2 are contracted, take up the positions 21a-24a. Each element 2 is bridged at its lower end by an arm 30 which carries a pulley 33 and other pulleys 34 are mounted on the base structure 1 intermediate the pulleys 33, a cord 35 being looped over the pulleys in succession. By this means, the cushion formed in the base of the leading element 2 will sense a change in the level of the ground surface 7 and rise or fall as necessary to slacken or tension the cord 35 so that the heights of succeeding elements 2 are automatically adjusted to follow the ground contour. By providing a single cord 35 round the periphery of the vehicle the elements on one side of the vehicle can be adjusted with respect to those on the other side if the vehicle is moving sideways.
