Title: Open-end spinning method and apparatus adapted for carrying  out this method
IPC: D01H4/08
Filed: 1972-05-30
Abstract: 1358810 Fibre feed in open end spindles SCHUBERT & SALZER MASCHINENFABRIK AG 30 May 1972 [29 May 1971] 25314/72 Heading DID In an open-end spinning machine fibre entering the spinning chamber 2 first makes contact with a surface 710 having a velocity relative to that of the chamber 2. This surface may rotate oppositely to the chamber 2 or codirectionally therewith but at a different speed. The surface 710 is spaced from the surface 24 of the chamber 2 by a distance less than the staple length of the fibre so that individual fibres bridging the gap are stretched and aligned. Yarn is withdrawn from the chamber either through the chamber shaft 21 which may contain a stationary guide tube 6, Fig. 5, or through the shaft 700 of the fibre contacting surface which has a false twisting effect or which may contain a stationary tube, Fig. 1 (not shown).

Abstract: 1,187,933. Pallet loading and unloading machines. HOLSTEIN & KAPPERT MASCHINENFABRIK PHOENIX G.m.b.H. 28 May, 1968 [24 June, 1967], No. 25369/68. Heading B8C. A machine for loading or unloading pallets with bottle crates and filling or emptying the orates, comprises a pallet lifting or lowering table beneath joined crate and bottle gripper carriages, the carriages travelling between the position over the table and adjacent orate and bottle supply or discharge positions. In one arrangement, a pallet lifting and lowering platform 1 is flanked by bottle and crate conveyers 5, 2 respectively and bottle and crate gripper heads 4, 3 are mounted on a carriage above. In unloading, the heads lower at the position shown to deposit empty crates on the conveyer 2 and grip a layer of bottles from a crate stack on a pallet on the platform 1. The carriage then moves to the left and the heads descend to deposit the bottles and pick up the emptied crates. The crate filling and pallet loading process is the reverse of that for unloading. Two such machines may be sited on opposite sides of a common crate deposit station, one unloading and delivering the empty crates to the station for picking up by the other. A crate conveyer may be fitted to supply or remove crates to or from the station. A single machine, Figs. 3, 4 (not shown), may combine simultaneous loading and unloading functions, having two pallet lifting and lowering platforms side by side flanked by bottle conveyers and a carriage overhead on which are mounted two bottle gripper heads with a crate gripper head between them.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 11, 1950.] Class 51 (i). A steam generator of the water tube type fired by solid fuel or a travelling grate a is supplied below the grate with primary air in quantities gradually increasing from front to rear of the grate in such a manner that in the front zone b an intensive combustion is initiated by the air, in the middle zone c the air pressure produces incipient " fluidization " of the fuel bed, and in the rear zone d the unburnt fuel remaining is lifted completely off the grate and driven towards the front of the combustion chamber by heated secondary air supplied through nozzles carrying flue dust collected in a filter n disposed behind the convection system of the generator. Heated tertiary air is supplied through adjustable nozzles a, t, and u disposed in the corners of the combustion chamber, which nozzles may be so arranged that the jets produce the known tangential whirling of furnace gases, Figs. 3 and 4 (not shown), the direction of whirling being alternated by adjacent groups of nozzles. The fuel conveyer b in the front wall of the combustion chamber is protected by the tube-lined wall i and also by a further stream of mixed cold and heated air issuing from nozzles v and the proportion of cold to heated air is increased by thermostatically controlled valves in the supply pipes as the speed of the fuel conveyer decreases until when the fuel conveyer stops cold air only is supplied. Ashes and slag are discharged over an ash-plate f into a shaft g where any fuel adhering thereto is completely burnt.

Clamping screws 21 lock the windscreen in a desired position. Similar clamps are fitted to control the movement of the hood 1 which may be pivoted about a horizontal axis in a similar manner to the windscreen, the rod portion 18 of the clamping screws acting as pivots. The hood supports are each formed of three parts 2, 3, and 4, parts 2 and 4 fitting telescopically over the cranked centre part 3 at each of its ends, each part being rotatable relatively to another. The hood may be adjusted laterally by rotating cranked part 3 around part 4, and being locked in a desired position by bolts 8. The lower part of the supports may be formed as a parallelogram movable on itself to give a resilient mounting for the hood, rubber bushes being used with the pivot pins between part 4, the links 30 and the upright 31, to increase the resilience provided by helical spring 32.

Teeth, artificial. - Pins of stainless steel or other metal are secured to artificial teeth formed with undercut recesses by inserting the pins into the recesses and then applying pressure to the pins so as to form thereon enlarged heads filling the recesses. Fig. 1 shows a tooth 1 with two undercut recesses 4, 5 having curved surfaces and enlarged at their openings 4a, 5a. The pins are formed with longitudinal bores 2a to facilitate the formation of heads within the recesses on pressure being applied by means of dies 6, 7. The figure shows a plain pin 2 before a head has been formed thereon, and an externally headed pin 3 after formation of the head 3a within the tooth recess. A two-part sleeve 8a, 8b is placed round the shank of a headed pin during the pressing operation. The pins may be centred in the recesses by means of pointed or rounded ends engaging corresponding depressions in the bases of the recesses. The recesses may be formed in a tooth during moulding by means of cores 11, Fig. 2, of metal, carbon, or asbestos which are baked with the teeth and afterwards removed by mechanical or chemical means, or by means of removable cores 13 carrying metal caps 12 which remain as linings for the recesses. Reference is made to known constructions in one of which a tooth crown with an undercut recess having an enlarged opening is secured to a root, similarly hollowed, by means of cement filling both hollows; and in the other of which a pin with a lateral projection is turned, after insertion into a recess in a tooth so as to engage an undercut portion of said recess.

Rectifiers 1, 2, 3, e.g. semi-conductor power diodes or mercury arc rectifiers to be tested in respect of forward and reverse operation, are connected between respective phases I, II, III of a polyphase supply in series with an inductor L1 and controlled rectifiers 1', 2', 3' which are switched in synchronism with the polyphase supply by a signal generator 13. Assuming that I is the most positive phase and that rectifier 2' is triggered on, then current will flow through forward biased diode 1 from P to Q, reverse biasing rectifier 2 and storing energy in L1. When I falls below II diode 1 is cut off and the energy from L1 dissipates itself through diode 2. This sequenee repeats for each pair of diodes sequentially testing their forward and reverse operation. A similar circuit for testing further diodes 4, 5, 6 may also be connected across the supply.
