Title: Improved pressure device for use in frictional beaming or winding-on operations in sizing machines
IPC: D06B3/04
Filed: 1923-12-04
Abstract: 214,925. Howard & Bullough, Ltd., and Airey, E. J. Dec. 4, 1923. Yarns, warping and beaming.-In devices for controlling the friction driving-devices for use in the beaming operations in yarn slashing or tape sizing machines, the pressure lever n for controlling the friction discs u has a slidable bracket m interposed between it and a lever r having a constant load t. The bracket m is moved down the lever n as the beam increases in diameter by mechanism operated by the presser shaft c and carries a roller o for engagement with the lever r. When the beam is substantially filled, the roller engages an incline w on an adjustable piece v on the lever, and allows a weighted catch y to engage the lever n to reduce the pressure on the friction discs u. When a fresh beam is being filled, an adjustable piece on the bracket m moves the catch y out of engagement with the lever n.

Title: Method of and apparatus for metering elongate material
IPC: G01B21/06
Filed: 1974-07-09
Abstract: 1480398 Metering yarn in textile machines NUOVA SAN GIORGIO SpA 9 July 1974 [10 July 1973 19 Oct 1973] 30458/74 Heading D1F In a method of metering a predetermined length of yarn in a textile machine having work units, e.g. an open end spinning machine reference pulses are generated proportional to the rotational speed of a yarn feeding member counting pulses are generated each for a given adjustable number of reference pulses, the counting pulses are supplied to each of the work units, the counting pulses are counted independently at each work unit, and when a given number of pulses has been counted at a work unit a control signal is generated to terminate the supply of material or yarn to the unit. In an open-end spinning machine, Fig. 2, yarn is drawn from rotors 11 at each station 10 by rollers 16 on shaft 20, generator 25 connected to shaft 20, feeds pulses to adjustable frequency divider 26 producing count pulses fed to a count unit 27 at each station 10. Each unit comprises a counter 27, device 27' for terminating the supply of count pulses, a signalling device, e.g. lamp 34, to indicate the termination, and manual counter reset 27". Each unit 28 counts a predetermined number of count pulses and then actuates an electromagnetic clutch 30 to stop sliver feed by device 13. If sensor 31' senses yarn absence it actuates termination device 27' and the signalling device and stops the feed device. Alternatively, in a multi-station winder, Fig. 3, shaft 35 supporting traverse rollers 36 actuates pulse generator 25 feeding pulses to frequency divider 26 feeding count pulses to a count unit 28 at each station. Unit 28 actuates yarn cutter 41 and signaller 34 when the required yarn length has been counted. An electronic slub catcher may replace yarn sensor 31', and may also operate cutter 41. Generators 25 may be photo-electric, magnetic, mechanical or pneumatic transducers.

Title: Improvements in centrifugal pumps or blowers and similar machines
IPC: F04D29/04
Filed: 1921-11-15
Abstract: 172,292. Beck, W. Nov. 30, 1920, [Convention date]. Balancing, moving parts. - A centrifugal pump has its axial thrust automatically compensated by an axial movement of the rotor caused by a variation in pressure in chambers round the rotor due to ejector action by the fluid pumped. The hub e carries the bladed rotor a and the flanges 1, 2 on the rotor with flanges on the casing form pressure chambers I, II, III, IV and connecting passages as shown. As the pump is operated, fluid is drawn off radially from the chamber III and axially from the chamber IV. If an axial thrust exists acting towards the suction pipe I, the rotor moves to the left and diminishes the cross-sectional area of the passage h, so increasing the ejector action. This reduces the pressure in the chamber IV and the rotor moves to the right to restore the balance. If the axial thrust acts towards the right the cross-sectional area of the passage h is increased and the ejector action is diminished.

Title: Improvements in or relating to the dehydration of aqueous systems containing fatty and non-fatty solids
IPC: F26B5/00
Filed: 1957-09-30
Abstract: In the dehydration, by heating at sub-atmospheric pressure, of a liquid mixture of non-fat solids, water and fatty material which is ordinarily subject to gel formation on dehydration, the concentration of discrete, i.e. particulate and non-colloidal, non-fat solids is increased during the dehydration before the stage at which gel formation normally occurs.  Fatty material includes not only glyceride oils and fats, but free fatty acids therefrom and the unsaponifiable fat-soluble concomitants of natural fats and oils. Liquid may be added to the initial mixture to obtain a minimum ratio of 2 parts of total fat to 1 part of non-fat solids.  Substances which may be dried by the process are milk, cream, ice-cream, whole egg, egg yolk, egg white, cake mixes, frostings, puddings, soups, chocolate, vanilla, yeast, blood, hormone and liver extracts, and fat-containing feeds. Example 1 is concerned with drying whole milk by concentrating, adding a mixture of butter fat and non-fat milk solids, e.g. lactose, vacuum-evaporating water from the mixture without denaturing the protein, and subjecting the water-free product to hydraulic pressure to remove excess butter fat and form blocks of dried milk.  U.S.A. Specification 2,651,647 is referred to.

Abstract: 359,689. Making chains. STROHHACKER, E., 122, Rathausstrasse Oeschelbronn, near Pforzheim, Germany. Oct. 13, 1930, No. 30563. [Classes 83 (ii) and 83 (iv).] Coiling; soldering; shearing-adjuncts.-Ornamental chains, of the shape shown in Figs. 1, 2, in which each link consists of two oval wire spirals of one and a half windings inserted one into the other, are produced in a machine which bends to shape and solders the links. The links are formed by internally-threaded sleeves 11, 12 of circular cross section with flattened ends and a mandrel 15 of oval cross section. The parts of the machine are driven by appropriate mechanism. Wire 17 is fed through winding mandrels 15 which are rotated three-quarters of a turn and oval wire spirals 4, 5 are unscrewed from the winding sleeves 11, 12 in front of knives 18, 19. The sleeves 11, 12, knives 18, 19 and pressers 20 move together until the free ends 6 of spirals 4, 5 are under holding tongs 8, 9. The end 6 of spiral 4 held in sleeve 11 is at this time under the opening of the end eye 29 of the link 1. A finger 10 presses the eye of the link 1 into engagement with the end 6 of the spiral 4 and the mandrels 15 are rotated another three-quarters of a turn to form the full link. The tongs 8 release the finished spiral and the tongs 8, 9 are advanced and rotated to grip the spirals at their centres, Fig. 11, (not shown). The knives 18 then advance and sever the spirals against the knives 19. The pressers 20 then move, to bend laterally, the ends of the spirals. Arms 23 of bending tongs 21 are then moved to bend inwardly the face ends of the half windings, and the holding tongs 8, 9 then move the spirals into a lower position, Fig. 15 (not shown). The tongs 9 move forward to push about twothirds of the spiral 5 into the spiral 4 and a solder thread 28 is pushed through an oblique guide 27 between the arms 7 of the spirals 4, 5. The pressing tongs 24 bend the ends 6 of the spirals into one plane and the arms 7 are pressed together. The tools 24, 25, 26, Fig. 5, (not shown) co-operate to finally shape the link, and the tongs 8, 9 are turned to bend the middle winding to a curb-link shape. The links are subsequently soldered. The solder guide is arranged on the mandrel 26 and the solder is sheared by co-operation of front edge of the guide and the mandrel.
