Title: Method and plant for straightening longitudinally extending hollow bodies
IPC: B21D3/08
Filed: 1966-04-04
Abstract: 1,140,396. Straightening. M. VON BUSHE and T. ALTENBRACHT [trading as TH. KIESERLING & ALBRECHT]. 4 April, 1966 [17 Sept., 1965], No. 14880/66. Heading B3E. Elongated hollow bodies, e.g. pipes of non- circular section, are straightened by being fed by rollers through a series of straightening means some of which bend the pipe without exceeding the yield point while one supplies a bending force which in conjunction with the bending forces applied by the first said straightening means is sufficient to bend the pipe beyond its yield point. Pipe 37 to be straightened is fed by driven rollers a through straightener sets b, c, d, the sets c applying a bending force P1 insufficient to bend the pipe beyond its yield point, while the set d applies a small additional force P2 which in conjunction with the forces applied by the sets c cause the pipe to be bent beyond its yield point. The straightener sets may be arranged so that five, rather than three, sets apply the required bending force. The straightener sets b, which function to absorb thrust forces produced by the bending, each comprise, rollers 12, Fig. 5, surrounding the pipe and carried by a support 11. The suppor 11 is adjustable vertically by a screw actuated lever 30 pivoted at 31, and the pivot 31 is carried in a support 32 adjustable to and from the pipe axis by a screw 34. The straightener sets c, d each comprise rollers 12a, Fig. 4, carried by a support 11a mounted on a lever 13 accommodating, in a slideway 27, a sliding block 26 on a pivot 25 carried by a pedestal 25a adjustable to and from the axis of the pipe during operation, by a screw 29. The other end of the lever is journalled on an eccentric 19, Fig. 6, keyed on a drive shaft 15 common to the straighteners c and d and serving, in operation, bodily to move the straightener sets. The eccentricity of the member 15 is adjustable, during operation, by wedge means 14 actuated by a worm 24, thus to vary the movement of the straightener set.

Title: Improvements relating to apparatus for the viewing of photographic transparencies
IPC: G03B23/04
Filed: 1955-05-23
Abstract: 770,727. Apparatus for viewing and sorting photographic films. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE OUDE DELFT. May 23, 1955 [May 22, 1954], No. 14883/55. Classes 97(1) and 98(23 An apparatus particularly useful for sorting medical X-ray negatives which require separation into a class for further examination and a class which need not be further examined comprises a feed magazine, appliances for moving negatives serially from the magazine to the plane of view of a viewing device, and means by which the examiner may operate a handle to lead the negatives selectively from the viewing device along at least two different paths of travel. The magazine may be suitable for separate negatives or roll film from which such negatives may be cut. Two negatives may be moved in each instance, one to end and one from the plane of view, and illumination from a lamp may be diminished during such movements. As shown, and described as an example of the apparatus, negatives 3 pressed down by plate 4 in obliquely positioned magazine 2 move to plane of view 6 in the viewing device comprising lamp 7 and lens system 8 and are then directed by divider 32 into one or the other compartments of collecting trough 48 as result of moving knob 35 of handle 34 rigidly attached to the divider from position A in full lines to either position B or C. The mechanism for so moving the negatives is motor driven, thus knob 35 on reaching position B or C actuates switch 25 to dim the lamp 7 and energize motor 11, and this is caused to move the right hand end of lever 16 rigidly mounted on a spindle 17 downwards, and hence via rod 39, lever 40, spindle 41 and suction cup 42 to extract the lowermost negative in a curved condition between two laterally positioned supporting strips 5 and out of the magazine. At the same time movement of the spindle 17 causes lowering of a negative holder 18 with ground glass 19 of the viewing system and hence release of an already examined negative to the path selected by the chosen position B or C of the knob 35. When suction cup 42 moves down as far as box 43 the suction is released and the negative on the cup falls to the holder 18 to be retained there by a lever 22 where movements are illustrated in Figs. 2-4 (not shown). Lever 16 is driven on downwards until it contacts one of the cams 38 and hence via lever 37 and rod 36 restores the knob 35 to its original, central position, after which lever 16 moves upwards and restores the negative holder 18 to viewing position, switches off the motor, illuminates the lamp at full strength and also closes and raises the suction cup 42 to enable it to adhere to the next negative in the magazine.

Inventor: EDWARDS ARTHUR JOSEPH
IPC: F42B22/42
Filed: 1917-10-17
Abstract: 129,325. Edwards, A. J. Oct. 17, 1917. Mines, marine.-Relates to devices inserted in mooring-cables to cause a sweeping-cable to pass through without dragging the mine, and consists in the combination of a slotted member 1 with a rolling member 6 shown in side view on Fig. 1 and in cross-section on Fig. 2. The slotted member 1 is attached to one part 5 of the mooring- cable, and the rolling member 6 is attached to a tail-piece 7 secured to the other part 8 of the mooring-cable. When a sweeping-cable encounters this device, it rides up the tail-piece 7, wedges the roller 6 aside, and passes into the slot 2; then it tilts the slotted member 1, causing the roller 6 to move to the other side of the slot and thereby to allow the sweeping-cable to slip out on the other side of the mooring-cable. The device is shaped or provided with a rudder 10 to cause it to assume the working position when the sweeping-cable bears against it.

Title: Wrapped yarns
IPC: D01H1/00
Filed: 1974-04-09
Abstract: 1457010 Spinning wrapped yarns; arrangements of rollers and guides TORAY INDUSTRIES INC 9 April 1974 [10 April 1973] 15576/74 Headings D1D D1F DIN and D1W Yarn which may possess twisting torque in one direction comprises a bundle of core fibres predominantly of staple fibres and "twistless" around which staple fibres are wrapped helically at a constant angle and evenly spaced therealong. The outside fibres may constrict the core fibres to cause them to bulge outwardly between the turns of the wrapping. The core bundle may be mixed with a continuous strand such as continuous filaments or spun staple yarn. The constituent fibres may be natural e.g. cotton, wool, silk, ramie, flax, jute, hemp, synthetic such as polyamides, polyesters, polyacrylics, polyolefines, regenerated, metal or glass or mixture thereof. Fibre length, denier or count and/or crosssectional form may vary. The yarn may be produced by drafting a bundle predominantly of staple fibres, false-twisting the bundle but not some outside fibres separated therefrom, uniting the bundle and fibres in the region when the bundle is subjected to false-twist so that, when the bundle relaxes and becomes "twistless", the outside fibres are helically wrapped therearound. As shown in Fig. 1, roving or sliver 1 is drafted between back and front rollers 2, 2', and 4, 4', through aprons 3, 3'. Divergent transfer aprons 8, 8', permit transmission of false-twist imparted to the bundle of drafted fibres by device 15 e.g. a torquejet, to the nip between rollers 4, 4'. Fibre bundle emerging from between aprons 3, 3', and advancing to rollers 4, 4', is subjected to the action of air currents created by rotation thereof so that fibres 7, 7' towards the centre of the bundle are moved outwardly leaving a major part as a bundle 6, the outward movement of fibres being limited by protectors 5, 5'. Bundle 6 passes through nip of rollers 4, 4', to form a bundle of false-twisted fibres 9 between aprons 8, 8', but outside fibres 7 are not intertwined therewith but advance in separated condition at 10 between aprons 8, 8'; fibres are then mechanically united e.g. by and especially in a constricted portion of, a suction pipe as at 12 (or suction pipes), which also draw(s) off staple fibre via a branch pipe 19 if yarn breakage occurs. Immediately the united bundle 14 passes the false-twisting point it is untwisted so that the core 9 becomes "twistless" and the outside bundle 10 helically wraps therearound to form the final yarn 16. Apron 8 may be omitted and the core 9 and fibres 10 combined by the converging action of two fixed collector guides on apron 8', Fig. 4 (not shown) or by a suction collector preceding and perhaps integrally or directly coupled with, a torque-jet nozzle (which applies the false-twist, Figs. 4, 5 and 6 (not shown).
