Title: Improvements in resilient devices
IPC: F16F1/42
Filed: 1957-12-04
Abstract: 857,611. Non-metallic springs. REGIE NATIONALE DES USINES RENAULT. Dec. 4, 1957 [Dec. 11, 1956], No. 37794/57. Class 108(3). Resilient plastic washers 10, Fig. 1, are mounted on a spindle 11 between a fixed member 12 and a movable member 13. As the member 13 moves to the right the washers are compressed until adjacent stiffened portions 15 abut each other. Webs 14, Fig. 5, of the washers may have stiffening ribs 18 on either or both sides, or may be reduced to radial spokes with spaces between. The washer may be modified by having holes 20, 21, Fig. 9 and curved spokes 22. Under compression the spokes adopt the shape shown in dotted lines. Fig. 10 shows an arrangement in which resilient shock absorbers are fitted between the stiffened parts, rings 27 in the centre and members 28 at the outer rim.

Filed: 1946-12-24
Abstract: 657,533. Knitting-machines. SCOTT & WILLIAMS, Inc. Dec. 24, 1946, No. 37892. Convention date, Dec. 28, 1945. [Class 74 (ii)] Claim is made to a knitting-machine comprising a cylinder, needles carried by said cylinder, a wrap yarn carrier, means for mounting, for radial pivotal movement of the carrier, that end of the wrap yarn carrier remote from the needles, means acting on the wrap yarn carrier near said mounting means for moving the carrier radially to present a wrap yarn to the needles, and an abutment mounted outside the needle circle engageable by the wrap yarn carrier to provide a relative circumferential movement between it and the needles, the shank of said wrap yarn carrier being flexible so that the last-mentioned movement occurs by flexing of the carrier throughout the shank from a point near the mounted end of the carrier while such mounted end moves circumferentially with the needles to avoid disturbance of timing relative to the means for acting thereon, irrespective of the deflection of the wrap yarn carrier caused by the abutment. Wrap yarn carriers 64 having flexible shanks 78 are rocked outwardly through the needle circle by cams on the main cam drum acting through Bowden wires 216, slides 212, cams 204 and sliders 72 having frangible butts. The lower ends 86 of the carriers are arrested by an abutment 224, the shanks 78 each flexing from a point near the mounted end thereof, whilst selected needles to be wrapped pass them, and are positively returned through the needle circle by cams 222. The lower ends of the carriers then spring back to their initial relative circumferential positions. The abutment is held in position by a spring, which allows it to yield if necessary. The machine is generally similar to that of Specification 658,955. Specifications 301,350, [Class 74 (ii)], and 532,577 also are referred to.

Title: Improvements in or relating to photographic cameras fitted with range finders
IPC: G03B13/20
Filed: 1946-12-31
Abstract: 634,317. Range-finders for photographic cameras. KODAK, Ltd. Dec. 31, 1946, No. 38145. Convention date, Jan. 5. [Classes 97 (i) and 98 (i)] In a camera in which a range-finder of the split field type coupled to focusing means includes a pair of coaxially arranged lenses movable together to the same extent for effecting coincidence of the images, the lenses are rigidly supported by a yoke member pivotally mounted on an axis parallel to the axis of the lenses, and from which an arm projects to engage a movable part of the focusing means. As shown, the light rays L<SP>1</SP>, L<SP>2</SP> are reflected by prisms 1, and pass through lenses 2 and coincidence prisms 19 to form an image at or near the prism faces 20, which is viewed by means of a field lens 21, erecting lens 22 and eyepiece 23. The lenses 1 are mounted coaxially on a yoke 4 which is pivoted about an axis parallel to, and below and in front of, the common axis of the lenses. The lenses 1 are thus free to move in arcuate paths. By appropriate choice of the pivotal axis, the horizontal component of the movement serves to bring the images into coincidence, while the vertical component provides corresponding parallax correction. The yoke has an extension 5 engaging a movable part of the focusing means, e.g. a cam 15, under the action of a spring. The yoke 4 may be axially adjusted by means of screw pivots 7 carried by a bracket 9, itself adjustable on a plate 10, forming part of the camera,. The arm 5 has a thin portion 5a enabling it to flex in the plane of the pivots 7, and is retained in engagement with the cam 16 by a slot 18 in a plate 17. To reduce the length of the range-finder, reflectors may be placed between the prisms 19 and lens 22, and between lenses 22 and 23 to " fold " the optical system. A frame 24 may be placed in front pf lens 23 to indicate the field of view.

Title: Recovery of unsaturated aliphatic nitriles
Filed: 1961-10-27
Abstract: Unsaturated aliphatic nitrile is recovered from a gas obtained by the reaction of a C3-C6 aliphatic olefine with ammonia and oxygen, by scrubbing the gas at a temperature below 20 DEG C. and at atmospheric and superatmospheric pressure with one or more aliphatic alcohols containing from 4 to 12 carbon atoms in the molecule, and distilling the alcohol to isolate the nitrile.  The gas may preferably be scrubbed with water e.g. at a pH of 2-5, before the treatment with alcohol or a mixture of alcohols.  The treatment with alcohol may be in two separate stages, and in countercurrent flow and a mixture of alcohols from an oxo-synthesis may be used. Examples describe the treatment of gaseous mixtures obtained from propylene, ammonia and air reacted in the presence of a molybdenum oxide, bismuth oxide and silica catalyst.  The alcohols used are C9 and C10 alcohols prepared by subjecting diisobutylene and propylene trimer respectively to oxo-synthesis and subsequent hydrogenation, and C7 alcohol derived from the catalytic hydrogenation of carbon monoxide.

Textured filament yarn is produced by introducing staple fibres and a tacky polymer substrate between a pair of rotating pressure rolls having continuous circumferential grooves and positioned face to face so that each male member of the grooved surface of one roll fits into the corresponding female member on the other roll to form at the nip point of said rolls cavities adjustable in depth and having shearing edges adapted to separate the resulting staple fibre-polymer composite into a plurality of tapes, with simultaneous consolidation of the tapes within said cavities. The grooves are preferably of substantially square cross-section and the rollers may be cooled. The polymer may be supplied as a continuous film or as a sheet of filaments. Preferably the rollers rotate at a rate faster than the feed-speed of the polymer, whereby orientation is effected. In one embodiment, two sets of filaments may be supplied, one of which is fully oriented and the other of which is fresh-spun and still tacky, and at least one of each type of filament is fed to each cavity. In a further embodiment only fully oriented filaments are fed, and these are heated to render them tacky, but without loss of orientation, as they are fed to the rollers. The staple fibres may be supplied randomly oriented, or lined-up, e.g. by means of electrostatic parallelization. Specified polymers are nylon, polyethylene and acrylonitrile.
