Filed: 1966-04-22
Abstract: High bulk textile yarns and fabrics woven therefrom having good covering power are made from a blend of fibres containing conventional staple-length fibres A and bulk giving fibres B having a staple length 65% to 85% of fibres A.  Fibres A have an irreversible yield point greater than 0.8 gms/den and an initial modulus greater than 20 gms/den while fibres B have an irreversible yield-point less, than 0.8 gms/den and an initial modulus less than fibre A and less than 30 gms/den; 35% to 67% of fibre A is included in the blend.  The longer fibres A may be of polyethylene terephthalate polymer or copolymer polyamides and copolymers thereof, poly acrylonitrile, and copolymers of acrylonitrile, rayon and natural fibres e.g. cotton and wool.  The shorter fibres B may be inherently crimpable polyesters and copolymers, bulked polyester copolymers and polyesters rendered irreversibly elongatable upon heating; a preferred fibre is a bulked copolymer of polyethylene terephthalate and polyethylene sulfoisophthalate.  To process the blend the speed of the lickerin in the carding engine is lowered to 350 to 600 ft./min. and the clearances between the cylinder and associated working surfaces is increased by 10% to 40% over the conventional setting.  Examples are given with full numerical data which illustrate the way in which the bulking properties of the "sensitive" fibres are protected by the longer staple length fibres.

Abstract: 440,036. Coal-washing plant. NORTON, B., Sandford. Hall, Claverley, Shropshire. June 16, 1934, No. 17927. [Class 82 (ii)] [See also Group I] Water overflowing from the main settling- tank of a coal-washing plant is subjected to clarifying treatment, such as to render it suitable for spraying the washed coal or innocuous for discharge, but the rest of the circulating water is not clarified. With plant as shown in the Figure, dirty water from different parts of the apparatus collects in a sump 4 from which it is delivered by a pump 5 through a pipe 6 to the main settling-tank 2. Water passes from the tank 2 to the washer 1 through a take-off 3. Water overflowing from the tank 2 through a pipe 14 is treated with chemicals or filtered in clarification apparatus 15, the clarified water being delivered through a pipe 16 to a clean water reservoir 17. Make-up water may be supplied through a pipe 18 and a pump 20 draws water from the sump 17 for spraying the washed coal. Slurry is run off continuously from the tank 2 through a pipe 7 and delivered to horizontal vibrating sieves 8, 9, arranged as described in Specification 327,845, [Class 82 (ii)]. Water and impurities pass from the sieves to settling-tanks 11, as described in Specification 354,986, [Group I]. Sediment from the clarification apparatus 15 may be delivered through a pipe 21 to the tanks 11 or to filtering plant or direct to the sump 4. When the plant is started after a period of rest the discharge of sediment through the pipe 7 is aided by the ejector action of water drawn from the tank 2 through a pipe 22 and forced through a pipe 24 by a pump 23. The first flow through the pipe 7 is directed by a two-way valve 26 through a pipe 25 to the settling-tanks 11, the later flow being directed to the sieves 8, 9, as described in Specification 440,096. An underground sump 27 is provided for the collection of drainage water, which can be returned to circulation by a pump 29 and pipe 28.

Patent GB-145789-A (GB)
Title: A new or improved process for refining tin and antimony
Filed: 1920-07-02
Abstract: Crude tin is refined by treating with dry chlorine which may be obtained by vaporizing liquid chlorine, filtering the liquid product, treating with water to decompose the chlorides of antimony, arsenic and sulphur, filtering again, and recovering tin from the pure solution of stannic chloride, for instance by reduction to stannous chloride and electrolysis.  To separate the antimony, the process is modified by heating the reaction vessel to 115-120 DEG  when the antimony pentachloride is decomposed into chlorine and solid trichloride which is therefore removed in the first filtration.  In a similar manner antimony is separated from metals such as lead, and is obtained as peutachloride alone when tin does not occur among the impurities.

Abstract: 313,614. Angel International Corporation. June 16, 1928, [Convention date]. Fastenings.-In machines for filling and sealing paper and like receptacles, a clamping strip is formed and secured on the collapsed end of the receptacle. The strip W of metal is drawn from a roll 124, Fig. 7, between a flanged guide roll 127 and over a die block 130, Fig. 25, formed with a rib 131 of progressively increasing V-shaped cross-section. A complemental member comprising a plate 132, conforming in shape to the rib 131, is pivoted at 133 and is adapted to be retained in operative position by a latch 136. The strip is drawn forward past rollers 148 by feed rollers 139, 140, partly shown in Fig. 28. The roller 139 is formed with a V-shaped peripheral recess corresponding to the formation of the strip, and the roller 140 is formed at the top of a rib with serrations which co-operate with corresponding serrations at the bottom of the recess in the other roller, so as to facilitate the feeding of the strip and to reinforce the bend by crimping at 147. A length is severed from the strip to form a closure by the apparatus shown in Fig. 22. After leaving the rolls 139, 140, the strip passes between longitudinally adjustable blocks 150, 151, and into a recess in vertically reciprocable blocks 157, 157<1>, then in alignment with the blocks 150, 151. The blocks 157, 157<1> are mounted on a head 162 adapted to be depressed into the position shown by a cam 174 so as to shear off the strip carried between the blocks. After the next upward movement, the feeding of the strip by the rollers 139, 140 delivers a severed portion between the jaws of the collapsing and securing mechanism.

Title: Improvements in signaling systems for automotive vehicles
Inventor: HOLLINS JESSE RICHARD
IPC: B60Q1/38
Filed: 1958-06-09
Abstract: 839,284. Road-traffic signals on vehicles; lamp-failure alarms. SIGNAL-STAT CORPORATION. June 9, 1958, No. 18391/58. Class 118 (2). [Also in Group XXXVII] In a vehicle signalling arrangement the stop lamps are used as turn signal lamps and are normally flashed together during a brake operation and are selectively flashed for an unbraked turn, while for a braked turn one lamp is flashed and the other steadily energized. As shown, a turn signalling switch operated by a lever 27 comprises a dielectric rotor 26 moving contact plates 25, 35 over stator contacts such as 37, 22. In the normal position shown, when the brake is applied switch BS is closed feeding the stop lamps LRSL, RRSL via a thermally operated flasher FL1. When a right-hand turn is to be made the rotor 26 is turned clockwise energizing the front right-hand signal lamp RFSL and the right-hand stop lamp RRSL via flasher FL2 and the ignition switch IS. If the brake is applied during a turn the current taken by the remaining stop lamp is insufficient to operate flasher FL1, hence this lamp is steadily energized. Pilot lamps PL1, PL2 are respectively connected to flashers FL1, FL2. In the event of failure of either or both stop lamps, PL1 will be steadily illuminated when the brake is applied since FL1 current will be insufficient to cause flashing. An additional switch FS (described as a " flare " switch) may be provided to give continuous flashing of the stop lamps in the event of emergency parking.
