Abstract: 415,212. Warp - tensioning devices for looms. BATTY, G. F., 18, Harlow Oval, Harrogate, Yorkshire. April 28, 1933, No. 12439. [Class 142 (ii).] One end at least of a warp beam 31 is supported by a sling 32 passing round the usual brake drum or collar 33, and the braking effect due to the weight of the beam and the warp thereon is increased by means of a weighted or spring influenced lever. This lever may be secured to one end of a chain &c. passing round the collar 33 and secured at its other end to a fixed point, or it may be connected to the bearing 36 of the beam spindle 34. As shown in Fig. 3, the weighted lever 42 is connected by a hand screw 39 and rod 38 with the bearing 36. The lever can be lifted and moved laterally to engage its lug 47 with a lug 48 on the frame to relieve the tension for " letting back " or can be lifted more to bring the bearing into a position for removal &c. of the beam as shown is dotted lines. As shown in Fig. 6, the lever 57 is lifted until its lug 56 engages above the lug 58 for " letting back " and is lowered until its lug engages below the lug 58 as shown to tension the loading spring 54. As shown in Fig. 8, the bearing at one end of the loom is connected by a rod 75, levers 74, 66 and a rock shaft 67 to one end of a lever 64, and the bearing at the other end of the loom by a rod 72 and a lever 69 loose on the shaft 67 to the other end of the lever 64, the middle of the lever 64 being connected to the weight lever 61. As shown in Fig. 9 the bearings at opposite ends of the loom are connected by rods 81, 82 to two bellcrank levers 83, 84 one of which carries the weighted lever 92 one end of which is connected to the other bell-crank 84 by an adjustable rod 90.

Title: Improvements in and relating to golf practising devices
IPC: A63B63/00
Filed: 1937-05-01
Abstract: 494,840. Golf &c. practising-appliances. DOE, J. D., and HARVEY, F. W. C. R. May 1 1937, No. 12482. [Class 132 (ii)] A device for use in practising golf, tennis, cricket or other ball-driving games comprises a screen constituted by two series of crossing wires 5, 9, each wire being connected to a movable element 7 adapted, when the wire is displaced by the passage of a ball through the screen, to bring into action an indicating means for the purpose of enabling the position at which the ball passes through the screen to be ascertained. The wires are stretched by springs 4, 8, and each movable element 7 forms part of a circuit through a corresponding lamp 16. In the normal position of the element 7 an insulated part thereof engages an opposing contact and maintains the circuit open. When the element is displaced by a ball striking its wire, the insulated part slips off the contact and the circuit through the lamp is completed. By observing the positions of the illuminated lamps, the character of the stroke may be deduced. The elements 7 are restored to circuit-breaking position by depressing a pedal 19, thereby pulling all the wires and centralizing the elements with the insulated parts against their contacts. A net may be provided at the back of the screen to stop the ball and direct it under the screen for replay. Protective netting may be arranged in front of the framework of the screen.

Abstract: 772,469. Sizing crepe yarn. ALGEMENE KUNSTZIJDE UNIE N.V. April 29, 1955 [June 29, 1954], No. 12533/55. Class 120 (3). A method for the manufacture of sized crepe yarn in which twisting, sizing, drying and winding is carried out in one sequence of operations, is characterized in that the twisting is carried out on a double twister delivering the yarn at a uniform tension, the tension in the yarn thereafter is reduced to a value below 10g. per 100 den., the yarn is brought into contact with the size whilst this reduced tension is maintained and after drying is wound under the same tension on to a bobbin. In the arrangement shown yarn 3 coming from a double twister 1 passes through a thread guide 5 to a detensioning roller 6. This roller 6 has a higher peripheral speed than the linear speed of the yarn 3 such that the yarn slips on the roller and the tension therein is reduced. The yarn then runs over a roller 7 provided with a groove and rotating in a size bath 8, then through a drying device 9 and after being dried is wound on a bobbin 10, via a thread guide 11 which is pressed under spring action against the bobbin 10, the package formed on the bobbin 10 being in contact with a driving roller 12. A waste roller 13 may be provided to take up waste yarn when the apparatus is first put into operation or in the case of a yarn rupture.
