Title: Improvements in and relating to thread curling devices
IPC: D02G1/08
Filed: 1962-02-27
Abstract: 928,877. Finishing yarns; twist tubes. SPINNER OSAKEYHTIO. Feb. 27, 1962 [April 17, 1961], No. 7540/62. Classes 120 (2) and 120 (3). In a curling process, a thermoplastic yarn 2 is passed through a tensioner 3 into a heating oven 4, wherein the yarn surface is melted, and the yarn (then in pliable condition) is fed under tension through a twisting device 8 so that on the subsequent path of the yarn to and around guide rollers 9, 10, 11, irregular curls develop therein. The yarn-twisting device, Fig. 2, comprises a cylindrical sleeve 19 mounted for rotation in a housing 13 and carrying rings 25 of V cross-section the limbs or portions 29 and 26 of which engage the inner cylindrical surface and extend over the end surfaces of the sleeve. Each ring is flared and of a material e.g. rubber, such that the frictional contact between the rings and yarn 2 is sufficient to impart a twist thereto during rotation of the sleeve. The portions 26 serve as protective covers for the bearings 14 and 15. A cover 24 protecting the housing may be removed to enable adjustment of driving belt 22 running between upstanding portions 20 and 23 on the sleeve. The radius of curvature of the inner surface of each ring may be greater at positions adjoining the ends than at positions intermediate thereof.

Abstract: 1,274,607. Selective signalling. CREED & CO. Ltd. 23 March, 1971, No. 7545/71. Heading G4H. A visual display device displays characters from a keyboard on a drum, and includes a character-signal store activating a recording unit via a converter, the recording unit forming latent images on the drum as patterns of dots in a rectangular array. The store is two closed-loop shift registers in series and feeds two converters each controlling a respective column of 7 magnetic recording heads, the two columns being mounted 4 character widths apart on a belt assembly by which the columns can be moved together parallel to the axis of rotation of the drum to each record 4 characters each as 5 columns of 7 dots (present/absent). After such recording, the drum is rotated through 180 degrees and the recorded images are developed by a powder applicator to render them visible. The characters from the printer are also sent to a store associated with a remote line-at-a-time printer. When the line is complete, a key on the keyboard is pressed to cause printing at the remote location and to erase the display.

[Class 78 (iii)] In a garage service-lift for motor vehicles, run-on trackways are provided which wholly or in part drop slightly as the lift is elevated so that the vehicle is supported on one or both axles leaving one or both pairs of wheels free. In the form shown in Fig. 1, flanged girders 12 secured to the usual central pillar head 11 and connected at their ends by transverse girders 13 to which are pivoted approach ramps 14, constitute the main part of the lift, the trackways 15 of usual trough shape being attached to brackets 17 slidable on vertical bolts 18 secured between the outwardly directed flanges of the girders 12. Downwardly extending legs or brackets 16, raise the trackways to the level of the tops of the girders 13 when the lift is at ground level enabling the vehicle to be run into position. As the lift is elevated, the trackways drop slightly, the vehicle axles being supported on the girders 12. When desired, the trackways may be supported, before dropping completely out of contact with the wheels, by screws 19 threaded through the cross-girders 13. In either case, the girders 13 rise above the level of the trackways to serve as wheel stops as the lift leaves the ground. In a modification, Figs. 4 and 6 the main trackways 21 are rigidly attached to the lift head and subsidiary platforms or tracks 23 with approach ramps 27 for the vehicle front wheels are carried on uprights 24 passing through the main trackways, so that when on the ground, the vehicle axle is raised, to be supported by brackets or jacks 29 when the platforms 23 sink as the lift is elevated.

[Class 103 (i).] A method of making an arcuate brake shoe from a rolled section having a flat flange 17 and one or more reinforcing webs 18 comprises cutting such section to form a blank of the required length, removing a part (shown dotted in Figs. 10 and 13) of the outer edge of the web or webs adjacent an end portion or portions of the blank to reduce the height thereof, and bending an end portion or portions of the flange inwardly so as to form a cam bearing face 22, Fig. 15, or a pivot end 15, Fig. 12, while causing the metal left in the web or webs, adjacent the end portion or portions to flow under forming pressure to reform the web or webs as an integral support for the inwardly bent end portion or portions of the flange. During the forming operation the face 22 may be curved in cross-section and this curved portion may be formed at an angle. The pivot end 15 of each shoe is cut at an angle to fit grooves in a pivot pin 14, axial movement of which adjusts the shoes. A portion of the web is bent to provide a bearing surface 27 for a conical-headed centralizing stud 28 threaded into the backing-plate 11. Return springs 12, Fig. 1, pull the shoes toward the backing-plate 11 bolted to the steering knuckle. The shoes may be suitably heat treated after the forming operations and the pivot ends 15 and bearing faces 22 may be hardened, for example, by the cyanide process.

Abstract: 549,251. Loading devices for valves and other elements. LAYSTALL ENGINEERING CO., Ltd.. and HEDGECOCK, S. July 2, 1941, No. 8326. [Class 135] [Also in Group XXVI] A loading device for valves and other actuated members comprises a spring or fluid buffer acting through transmitting mechanism which is automatically reduced in axial length when the spring has been compressed to a predetermined amount so that a further movement of the valve is obtained without the application of an increased thrust. In the form shown in Fig. 2, a loading spring 14 is arranged between a fixed abutment 16 and a floating abutment 13 slidably arranged in a tubular extension of the valve member 12. A light spring is arranged between the valve member and the abutment 13 which is provided with an aperture controlled by a spring-loaded valve 19. The whole device is immersed in oil so that chamber 24 is filled through port 23 and passage 22. During the initial movement of the tubular part 9 it slides over the abutment 13 and seals the chamber, further movement is then only possible by compressing the spring 14. When this compression reaches a predetermined value a pin 21 on the abutment 16 unseats the valve 19 permitting the release of oil from the chamber and the further opening of the valve without further spring compression. In a modification when the valve is unseated the floating abutment moves backward to release a part of the loading pressure while permitting the valve remaining in the same position. In the form shown in Fig. 7 the hydraulic transmission is replaced by a spring-loaded trip-catch 27 released by a ballended pin 21 on the abutment 16 engaging a cam surface on the catch.
