Patent FR-1602530-A (FR)
Title: Comb roller with angularly adjustable teeth
IPC: D01H5/02
Filed: 1968-09-25
Granted: 1970-12-21
Abstract: The teeth are carried on transverse needle bars located in aligned peripheral slots of axially spaced discs carried on a common rotatable shaft. An end of each bar is formed with a crank which engages in a cam-track in a fixed end plate, the cam-track acting to pivot the needle bar to ensure that the needles are perpendicular to the fibrous web during its passage over the needles, and to further pivot the bars so that the needles engage cleaner bars, arranged between adjacent needle bars, when the web has been disengaged from the needles. Pref. the cleaner bars are rotated by a similar cam in the other fixed end plate.

Abstract: 1,052,972. Projection apparatus; photochromic materials. COMPAGNIE DE SAINT-GOBAIN. March 26, 1964 [March 26, 1963], No. 12947/64. Headings G2C and G2J. [Also in Division C4] Apparatus for viewing or projecting positive images from negative originals, cine or still, comprises an ultraviolet light source 1 and filter 2 which illuminates through condenser 3, a negative cine film 4 whose images are focused on to a photochromic plate 6 by a lens 5, passing ultraviolet light of wavelength greater than 3000 A, to give positive image of the same size as the original. The positive image may be viewed directly through a magnifying glass or projected on to a screen8 through a further condenser 11 and objective 12. For this latter purpose, the photochromic image is illumined with visible light from filament lamp 9, using semi-transparent mirror 10, which may be treated to be transparent to ultraviolet light. Preparation of a photochromic gel is described, giving a response time suitable for cine pictures. Light other than ultraviolet may be used for different photochromic substances.

IPC: D01D10/04
Abstract: 1,054,567. Spinning yarns. MONSANTO CO. Oct. 30, 1964 [Nov. 12, 1963], No. 44410/ 64. Headings D1F and D1W. A zero-twist yarn of circular cross-section is composed of straight, uncrimped filaments, e.g. of nylon, polyester, polyethylene, polypropylene, polyurethane, vinyl polymers and copolymers, polyacrylonitrile, in parallel contiguous relation and cohered at random points along the length of the yarn whereby the yarn has unifilar properties. The filaments, particularly if freshly drawn, may be relaxed or relieved of latent overstrain so as to reduce tending to retract: they may be of circular cross-section, or multilobal and/or hollow. The unifilar property is imparted to the yarn by false-twisting it as it is forwarded, applying a small amount of a liquid evanescent solvent thereof while the yarn is so twisted, untwisting, then heating the yarn to dissipate the action of the solvent, and collecting the yarn, usually under minimum tension. Examples of the solvent are specified. As shown, untwisted yarn or a bundle of incompletely oriented filaments, as supplied directly from the filament spinning machine or from a wound package, is passed to feed rolls 2, around a snubbing pin 3 (which may be heated) thence around draw and separator rolls 4 and 5 rotated at such speed in relation to the speed of rolls 2 as to stretch the yarn. As the yarn progresses along rolls 4 and 5 it is cooled and the tension therein decreases with each succeeding wrap. Yarn is led from roll 4 in a figure of eight path in a reverse wrap around roll 4 and a heated roll 7 so that it is frictionally engaged by a flange 6 and slightly false-twisted thereby. The twist runs towards roll 4 and the liquid solvent is applied to the yarn as it brushes across the surface of a wick 8. The yarn is heated by contact with roll 7, so that the untwisting yarn is dried to dissipate the action of the solvent, and then cooled by renewed contact with the roll 4 on each passage on a figure of eight path. Yarn leaving roll 7 receives a finish or lubricant from a wick applicator 14 and is advanced, e.g. by another pair of feed rolls (not shown) under low tension around a guide roll 10 to be wound, without twisting, into a package 13.

Abstract: 1,143,641. Wire tensioning devices. MAX PAUL & SOHNE MASCHINENFABRIK. 5 May, 1966 [5 May, 1965], No. 19846/66. Heading F2G. A jack-anchor plate assembly for prestressing and anchoring steel wires 1 or bundles of steel wires in prestressed concrete consists of an anchor plate 3 provided with a plurality of bores 9 in which the wires are anchored by wedge members 4, and an hydraulic jack comprising an annular piston 6 working in a cylinder 7 having provided in the bottom 12 thereof a plurality of bores 13 for pistons 14, the bottom 10 of the piston 6 having a corresponding number of bores 11 receiving conical wedges 8 and annular wedge-operating pistons 15. The plate 3 being secured to a structural part, the wires are first connected to the plate by the wedges 4 and also passed through the wedges 8 whereby the jack is brought to bear on the plate. Hydraulic fluid admitted to the pistons 15 causes the wedges 8 to clamp the wires fast to the piston bottom 10. Hydraulic fluid admitted to the cylinder via the pipe 22 moves the piston in the direction of the arrow 28 to tension the wires, and hydraulic fluid is then applied to the pistons 14 to drive the wedges 4 to secure the wires in the plate 3. By introducing hydraulic fluid via the pipe 26 to the cylinder space 29 the piston 6 moves back to the position shown whereby the wedges 8 are brought into abutment with the cylinder bottom 12 to free the wires from the wedges and to allow withdrawal of the jack.
