Title: Improvement in wind engine
IPC: F03D5/04
Filed: 1928-06-30
Abstract: 303,725. Madarasz, J. D. June 30, 1928. Dynamos, driving.-In a wind motor comprising a number of rotors utilizing the Magnus effect, and adapted to drive dynamos, the rotors 10 are mounted to move bodily through a path which is preferably circular, and means are provided for reversing periodically the direction of rotation of the rotors on their own axes. The rotors are mounted on towers 15 carried by frames 11 which are supported on wheels 12 adapted to run in a track 13. Rotation is imparted to them by reversible electric motors 20 which are fed through non-rotary contact strips 24. The strips are arranged so that the motors are reversed as the rotors pass along the track in a direction parallel to the wind, and to secure this effect, the strip-carrying frame is adjusted by a wind vane 26. The rotors may he revolved on their own axes by mechanical devices. For the generation of power by the system, the axles of the travelling wheels 12 may be geared to electric generators 37 carried by the frames 11, the current being conveyed by trolleys 41<c> to conductor rails. Instead of running on a closed track, the rotors may be oscillated, or may be mounted on a turntable.

Title: Improvements in or relating to high-speed yarn winding machines
IPC: B65H63/028
Filed: 1954-06-30
Abstract: 813,681. Stop mechanism for yarn winding machines. HOLT Ltd., T., and BRIERLEY, E. Sept. 30, 1955 [June 30, 1954], No. 19121/54. Class 120(2) Stop motion means for high-speed yarn winding machines of the type for winding yarns &c. from hanks carried on swifts on to packages which are surface driven or driven direct and operating on entanglement of the yarn includes means to stop the package during roller simultantously with means to positively arrestthe turning movement of the swift and also to simultaneously adjust the tension in the yarn between the swift and the package to prevent undue tension being applied to the yarn and is such that when the entanglement has been removed and the winding restarted, the tension adjusting means returns to its inital position and the package and the swift are free to turn simultaneously. In the arrangement shown, when an entanglement of the yarn on the swift 10 occurs there is a sudden drag which causes the pulley 35 to be tilted about its pivot, so compressing spring loaded plunger 36 and causing cam 39 to push against the compensator lever 40. This action causes a brake to be applied to driving roller 41 and a freeing of block 42 from its abutment with the bearing 15a. The lever 40 moves forwards and upwards such that trigger 43 presses against the extension 20a of a brake rod 20 to free it from its keeper groove 27 whereupon brake rod 20 is forced outward by spring pressure and it outer end 20b is projected into an adjacent hole 30 in the periphery of brake pulley 29 to stop rotation of swift 10. At the same time, tension pulley 32 is swung outwards, under the influence of weight 33, to take up the slack in the yarn Y. In the event of breakage of the yarn or when it becomes exhausted the resistance of the yarn on the pulley 35 is removed and the spring-loaded plunger 36 presses against the bracket 34 and causes it to swing about its pivot in a clockwise direction, accelerated by the weight of the pulley, such that the heel of the cam 39 strikes the lever 40 causing the stopping of the package and the swift as before.

Title: Improvements in or relating to valves more particularly for internal combustion engines
IPC: F01L1/28
Filed: 1955-07-01
Abstract: 816,392. Valves; inlet and exhaust passages. BUCHI, A. J. July 1, 1955 [July 2, 1954], No. 19163/55. Classes 7(2) and 7(6) [Also in Group XXIX] The inlet valve, Fig. 1, of an internal combustion engine comprises a bell-shaped head 1a in the domed or semispherical upper portion 1b of which are three, as shown, or more triangular orifices 1c, Fig. 2. with their apices adjacent the valve stem 1d, the orifices opening into an annular duct 4a communicating with the exhaust passage 4; the wall portions between the orifices 1c are straight as viewed in Fig. 2 and the orifice edges are rounded; the axial height of the orifices is less than the circumferential length at the base of the orifices. The duct 4a is as arranged with regard to the orifices 1c and passage 4 to reduce velocity and pressure losses to a minimum; the exhaust gases go round the head 1a in opposite directions and merge into a common stream in the passage 4. The poppet exhaust valve 2, Fig. 1, the seat of which opens into the inlet passage 3, formed as a spiral, co-operates with the mouth of the head 1a whilst its stem passes through and is supported by the stem 1d of the inlet valve 1; the valves 1, 2 are urged to the closed position by helical springs 8 and 7 respectively. The inlet valve 1 is supported by a cylindrical portion 11 that slides in an opening 12 in the cylinder head, the portion 11 being formed with a labyrinth or ring seal 13 to prevent communication between passages 3, 4. In a modification, the exhaust valve is loaded by a twin-coil torsion spring the coils being arranged one on each side of a yoke on the valve stem. The inner valve may control the air or mixture and the outer valve the exhaust gases. In another modification, the wall portions between the orifices are curved, as viewed axially, to obliquely join the body part of the head thereby permitting relative axial movement between the body part and the valve stem to accommodate any expansion resulting from the passage of exhaust gases therethrough. The valves may be used to control the admission and discharge of gases to and from a gas mixing chamber instead of an engine.

Abstract: 1345453 Yarn-stretching apparatus AKZO NV 26 April 1972 [4 May 1971] 19326/72 Heading B5B [Also in Division D1] Apparatus for heat treating a plurality of elongate elements (e.g. yarns of synthetic filaments in a hot stretching process) at a temperature above 100‹ C. comprises a heat treatment zone 1 formed with a plurality of heating chambers 9 passing therethrough, the number of chambers 9 corresponding to the number of elongate elements to be treated, each treatment chamber having a lateral pipe 4 for the introduction of steam or other treatment medium and pressure locks 13 formed at its inlet and outlet ends. As illustrated the heating chambers are preferably formed by laterally spaced, parallel tubes 2 passing through an outer chamber 5, tubes 2 and chamber 5 being fed with steam under pressure from steam source 17 via inlets 7 and 4 respectively. At their downstream end each treatment chamber 9 is preferably provided with a compressed air ejector 14 for re-threading any yarns which break during the heating process. The pressure locks 13 preferably include throttle members which allow the cross-sections of flow ducts passing therethrough to be altered as required. In the preferred embodiment (Figs. 3-17, not shown) the adjustable throttle members are formed by rotatable cylinders formed with recesses having a cross-section equal to that of the flow duct and mounted in bores perpendicular to the flow ducts, alternate cylinders along the length of the flow ducts being separated by bores which form turbulence zones. These cylinders are rotatable between a position in which only a narrow channel for passage of the yarn is present and a position, used when re-threading of a yarn is necessary, in which the whole cross-section of the flow ducts are open. The apparatus allows filaments of, for example, nylon to be hot stretched using steam at 152‹ C. with a higher yarn throughput than conventional apparatus.
