Title: Improvements in methods and apparatus for winding skeins of yarn
IPC: B65H54/56
Filed: 1940-10-17
Abstract: 544,589. Reeling yarns. AMERICAN VISCOSE CORPORATION. Oct. 17, 1940, No. 15391. Convention date, April 2. [Class 120 (ii)] Skeins of yarn are wound on a reel with the yarn laid in side by side relation forming a diamond pattern by guide means which is reciprocated across the reel with a varied length of travel. As shown the yam guide 4 is carried by a bell-crank lever 5 pivoted to the frame and oscillated by a link 8 pivoted to the arm 6 of the lever and to a gear 9 driven from the shaft 2; the pivot 13 connecting the gear 9 to the link 8 has an eccentric portion 12 engaging the link and carries a ratchet wheel 14 engaged by a pawl 18 pressed by a spring 19 and pivotally mounted on the eccentric hub 17 of a star wheel 15 pivotally mounted on a pin 16 in the gear 9. As the gear 9 rotates the star wheel engages a stop member 20 supported by a pin 21 and is intermittently rotated so that the pawl actuates the ratchet wheel which rotates the pivot 13 and varies the stroke of the link 8 and progressively shortens the traverse of the yarn guide 4 across the reel. The Specification as open to inspection under Sect. 91 comprises also methods and machines in which the traverse is maintained constant and the path of the yarn guide is varied. This subject-matter does not appear in the Specification as accepted.

The reflector 11 is slightly concave and is secured by screws 20 to a shoulder 19 on the housing 1. Alternatively this reflector may be a flat annulus or a painted or coated surface of the housing itself. The three reflecting surfaces can alternatively be faceted or diffusive or to a predetermined degree light absorbent.

Abstract: Natural or synthetic rubber or a resinous polymer contains as antioxidant either a polymer of an alkenylphenol of formula <FORM:0971753/C3/1> wherein R1 is H, alkyl or cycloalkyl and R2 and R3 are H or inert substituents, or a salt of such a polymer. A reducing agent, such as hydrazine, hydroxylamine or N,N-dimethyl-hydrazine, and/or a chelating agent, such as the disodium salt of ethylenediamine tetra-acetic acid or the trisodium salt of N-hydroxy ethylethylenediamine triacetic acid, also may be present.

Abstract: 1,155,001. Hydraulic reciprocating motors. FERRANTI Ltd. July 11, 1967 [April 12, 1966], No. 15838/66. Heading F1A. In a linear hydraulic motor comprising a translator 13 movable relative to a stator 11 by the sequential pressurization of cylinders A, B... in the translator, so that hardened steel balls A1, A2... in the cylinder engage a cyclic edge profile 12 on the stator to cause the relative movement, the sequential pressurization of the cylinders is controlled by spool valves P1, P2, &c. operated in sequence in response to signals emitted each time the translator moves through a distance equal to a predetermined fraction of a wavelength of the cyclic profile. The spool valves P1, P2 receive hydraulic fluid Fs through channels II or 12, dependent on the position of a changeover valve 21, the channel not pressurized being connected to exhaust Fe. Each spool valve (there may be more than two) controls the supply and exhaust to two groups of cylinders, one group being pressurized while the other is exhausted. Several methods of producing the signals for causing the spools to changeover are described. In the first method, the signals are produced by an optical fringe-counting method, in which a photocell 26 on the translator traverses a grating 25 of alternate light and dark bands, whereby electrical signals S1 S2 are emitted at each predetermined fraction of a wavelength to actuate the spools via relays R1, R2. Alternatively the electrical signals are emitted by switches actuated by cams engaging the profile. In the second method the spools are actuated hydraulically, Fig. 5 (not shown), by fluid directed thereto by pilot valves operated by the profile.

Title: Preparation of diorganotin maleates
IPC: C07F7/22
Filed: 1966-04-12
Abstract: Diorganotin salts of maleic acid are prepared by mixing an organo tin oxide RR1SnO, where R and R1 are hydrocarbon radicals, with a suspension of molten maleic anhydride in an organic liquid in which the maleic anhydride and the tin oxide are substantially insoluble. The suspension is strongly agitated during the preparation and is preferably heated to between 60 DEG  and 120 DEG  C.  The suspension is cooled and the product, which solidifies as grains or prills, is then filtered off and dried.  The radicals R and R1 may be alkyl such as butyl, hexyl and octyl, aryl such as phenyl, aralkyl such as benzyl, cycloalkyl such as cyclohexyl or unsaturated. In the example maleic anhydride and dibutyl tin oxide are reacted in isooctane at a temperature of 75-80 DEG  C.

Recessed portions of the plates co-operate to form eight cylindrical seats, such as F<2>, F3, F<4>, which extend parallel to the faces of the plates and receive the rods or tubes at an angle of 45‹ with each other. The plates are also formed to provide two coaxial cylindrical seats in hub members M which extend at right-angles to the axes of the seats F<2>, F<3>, F<4>. The inner end of each of the seats is provided with the recess e, and the outer end may also be recessed as shown at e<1>, Fig. 2, for engaging the correspondingly-formed end of a rod or tube passing through the coupling. In a modified construction, the coupling comprises two parts adapted to receive four rods lying at right-angles to each other and in the same plane, and a central aperture G in the coupling extends at right-angles to the plane of the axes of these rods and is adapted to receive slidably a rod which passes completely through the coupling. The coupling shown in Fig. 7 comprises two outer parts N, P and an intermediate part O, the semicylindrical recesses being provided in the contacting faces of these parts so as to form between them the desired seats for the rods.
