Title: Improvements in or relating to strand-crimping processes and strand-crimping apparatus
IPC: D02G1/00
Filed: 1959-01-12
Abstract: <PICT:0907823/IV(a)/1> A "strand," i.e. a monofilament or twistless or twisted multifilament bundle, ribbon or tow, composed of molecularly oriented, linear polymeric material, e.g. nylon, is crimped by plasticizing the tensioned strand at one side only thereof, rolling this side simultaneously with the opposite side so as to forward the strand against the tension and to flatten the one side (thereby producing a molecular orientation differential at opposite sides) and deplasticizing the rolled portion of the strand with the one side having been lengthened relative to the opposite side.  A thermoplastic strand may be heated to produce a temperature differential at opposite sides and plasticize one side, or a chemical solvent or swelling agent may be selectively applied.  The crimp deformation comprises helical coils or loops of varying diameter, direction of helix and frequency of occurrence, and component filaments are irregularly crinkled or bent and of flattened or elliptical cross-section, Figs. 4-9 (not shown).  As shown in Fig. 2, a strand 1 from bobbin 2, passing through guides 3, is pretensioned by a gate-tensioner 4, forwarded, plasticized and rolled by hot and cool nip-rollers 5 and 6 into a strand 11 which is opened by an electromagnetically driven vibrator 7 and wound on to a cone 8 by roller 9.  Before or after winding, the strand may be hot-relaxed, as by passage through (or dwell in) a heated chamber or over one or more heating surfaces at a temperature approaching the plasticizing temperature, in order to produce strand 111 of intensified crimp. The strand may be removed from the cool roller 6 by a doctor blade, Fig. 10 (not shown).  Rolling apparatus, Figs. 14-17 (not shown), incorporates hollow rollers 5 and 6 adjustably loaded and mounted (with their axes normally in a common horizontal plane) and reversibly driven by electric motors. Roller 5 comprises internal, automatically-controlled, electrical heating elements; roller 6 is cooled by circulation therethrough of fluid such as water. Electrical connections are effected through slip-rings.

Abstract: 819,014. Barometers. WALZ, K. B. Jan. 17, 1958 flan. 18, 19651, No. 1497/56. Class 106 (2). An aneroid barometer comprises a graduated dial 11 rotatable on a horizontal axis 23 and coacting with a fixed pointer 10, a rod 8 connecting a point 9, Fig. 4, on the dial with the fixed frame and including aneroids 7 so that the length of this rod depends upon the atmospheric pressure, and a further rod 27, of fixed length in operation, connecting the point 9 with an axis 30 eccentric to the axis 23. Expansion or contraction of the aneroids causes the dial to rotate relatively to the fixed pointer. In Fig. 1 the dial 11 is fixed by screws 31 to a rotatable frame comprising two overlapping rings 1, 2 fixed together at 3, 4 and mounted on a bushing 21 rotatable on the shaft 23. An endless steel band 5 of circumference slightly greater than the inner periphery of the ring 2 is inserted within the latter so that an inwardly projecting resilient bulge 6 is formed, to this bulge the outer end of the rod 8 is fixed by a cross-bar 9 and bolts 25. The inner end of the rod 8 is screwed into the bushing 21 and the aneroids are adjustable by a nut 27. The ends of the crossbar 9 are connected by telescopie rods 27, 28 adjustable by set screws 26 to shaft 30 mounted eccentrically on the shaft 23. Expansion and contraction of the aneroids 7 causes the crossbar 9 to move radially and the dial to turn. For balancing the parts, the ring 1 has a counterweight 18 on a screwed rod 32. Unbalance due to the radial movement of the cross-bar 9 and associated parts is compensated by a ball 34 rolling freely in an annular circular container 33 in the ring 1. An additional dial or pointer may be geared to the dial 11 to provide more accurate readings. Fig. 7 shows a modification in which the rod 8 includes a rack 45 engaging a fixed gear-wheel 46 on the shaft 23 and spokes 44 of the dial 11 correspond to the rods 27, 28 of Fig. 1. Expansion or contraction of the aneroids causes the rack to turn on the fixed gear-wheel and rotate the dial 11.

Filed: 1953-01-20
Abstract: 729,081. Shaft-couplings. DUNLOP RUBBER CO., Ltd., TREVASKIS, H. W:, and DUNLOP RIM & WHEEL CO., Ltd. Dec. 30, 1953 [Jan. 20, 1953], No. 1587/53. Class. 80 (2). [Also in Group XXXIV] In an automatic braking apparatus for aircraft of the type described in Specification 676,708, the clutch mechanism differs from that illustrated and described in that Specification in that it comprises. an improved type of clutch mechanism which will provide a light torque in one direction and a heavy torque in the other direction. Fig. 1 is an exploded perspective and partly sectional view of the automatic braking apparatus in which an annular drummember 3 is associated with the flywheel 4 of the apparatus and an annular member 19, which is located within the drummember 3, is driven by the housing 1 by means of pegs 21 located in holes 20 in the annular member; the housing being driven by the aircraft wheel through the rubber tyre 2 which contacts the inner periphery of the wheel rim. The. annular member 19 is provided with a helically coiled spring 22 around its outer periphery, one end thereof being secured to the annular member at 23 so that when fitted within the drum-member 3 there is an interference fit against the inner peripheral wall of the drum-member. The lay of the spring, taken from the anchored end, is the same as the direction of rotation of the housing 1 for forward movement of the aircraft, the arrangement being such that on rotating the annular member 19 relative to the drum member 3 in the opposite direction to the lay of the spring 22 a light torque only is obtained due to the light frictional engagement between the spring 22 and the drum-member 3. On rotating the annular member 19 in the other direction, however, the frictional engagement between the spring 22 and drum member 3 causes the spring to tend to unwind and jam against the drum member, this creating a heavy torque.

Abstract: 1,139,691. Position digitizer. CARL ZEISSSTIFTUNG [trading as CARL-ZEISS]. 13 Jan., 1966 [14 Jan., 1965], No. 1593/66. Heading G4H. In a system for marking one lead in each of a plurality of groups of ten leads in accordance with the position of a coded scale, each of a plurality of sine-wave shaped patterns, Fig. 1a, on the scale-adjacent patterns having decimally related periods-is sensed by quadrature spaced photo-electric cells to produce sine and cosine signals which are applied to the deflection plates of a corresponding cathode ray tube to cause its beam to impinge upon one of ten electrodes on the face of the tube, thereby causing one of ten output leads to be marked. Potential transitional errors are eliminated either by having " lead " and " lag " pairs of cells for each track of the scale and conventional switching circuitry, or by using c.r.t.'s having an additional deflection coil around their necks which can be used to simulate the effect of lead/lag sensing. The light intensity at each cell can be increased by bringing light to it by light guides from several points spaced apart by complete cycles along each sine-wave pattern. The highest order track on the cell could be sensed by different means, e.g. a mechanical feeler.

Title: Improvements in or relating to process for the manufacture of lead salts of fatty acids
IPC: C08K5/098
Filed: 1948-01-20
Abstract: Lead salts of fatty acids are prepared by mixing lead monoxide and a long-chain saturated fatty acid containing from 6 to 30 carbon atoms in amounts so that for each 2 mols. of fatty acid there are present from 1 to 3 mols. of lead monoxide in an aqueous slurry and in the presence of a catalyst.  The catalysts are aliphatic compounds containing combined oxygen which are at least sparingly water-soluble.  The reaction may be carried out at an elevated temperature, e.g. between 25 DEG  and 65 DEG  C.  Suitable catalysts are saturated alcohols and ethers containing from 2 to 8 carbon atoms, e.g. monohydric alcohols such as isobutanol, or glycol ethers such as ethylene glycol monobutyl ether or diethylene glycol monobutyl ether.  The quantities of reactants may be such that the water is present in an amount of 3 to 16 parts by weight of the lead monoxide and from 2 per cent to 15 per cent of the weight of water of an aliphatic alcohol or ether containing from 2 to 8 carbon atoms. In the examples lead salts of stearic, pelargonic and myristic acids and basic lead salts of stearic, caproic and lauric acids are prepared.  Another acid mentioned is melissic acid.
