Abstract: 946,202. Fibre feeding apparatus. BIRFIELD ENGINEERING Ltd. April 21, 1960 [Jan. 22, 1959], No. 2422/59. Heading D1N. An endless spiked conveyer band of a hopper feeder passes in its return run through a vacuum chamber so arranged that an air flow into the chamber serves to suck fibres off the band. An oscillatory comb 16 is arranged adjacent the upper run of the band 8 to provide an operative downward stroke close to the band and an inoperative return stroke withdrawn from the band. This comb 16 is mounted on an arm 17 connected to a floating link 18 and pivoted on a crank 19. A grid of spaced parallel bars 24 is arranged along the band 8 with the spikes of the band projecting through the grid. In the vacuum chamber formed between walls 25, 26 is rotatably mounted a foraminous condenser roll 27. According to the Provisional Specification, the return run of the band may have a vertical section and oscillating rollers carrying spikes, combs, brushes, or teeth may act on this section and, in addition on the upward run of the band. Belts may also be provided at the delivery of the fibres, and may be followed by an opening, teasing or blending drum. Specification 835, 215 is referred to.

Title: Process for the manufacture of low phosphorous pig iron
IPC: C21C1/00
Filed: 1964-01-21
Abstract: Low-phosphorus pig-iron of high carbon content is produced by subjecting crude iron to vigorous agitation in a basic lined vessel into which oxygen is injected while iron oxide-containing material, carbonaceous material and slag formers capable of binding phosphorus are added, the process being characterized in that a layer of solid carbonaceous material is maintained on top of the slag, the iron oxide content of which is in the range 3.5%-10%.  Agitation may be effected by carrying out the process in a rotary furnace, or in the shaking ladle apparatus described in Specification 801,156.  When the phosphorus content of the slag is high in relation to silicon, calcium silicate possibly in the form of steel making or blast furnace slag, may be added to the vessel.

Abstract: 701,917. Stuffing-box substitutes. DOWTY EQUIPMENT, Ltd. Feb. 1, 1952 [Feb. 7, 1951], No. 3038/51. Class 122 (5). [Also in Group XXXII] A liquid spring comprises a low pressure reservoir R, surrounding the plunger 19 adjacent the packing gland assembly, and containing lubricating oil of greater viscosity than that of the liquid in the working chamber A of the spring. The effects of the relative viscosities of the oil and liquid, and the action of the packing gland assembly, so combine that repeated reciprocation of the plunger causes some of the reservoir oil to be carried into the chamber A (despite its higher pressure). The packing gland assembly comprises a housing 30 bored to receive a laminated packing B which is acted on by a differential area piston 39. The assembly is retained between a plate 45 and an end cap 18. The packing B comprises a hard washer 34 of processed leather material, such as that known under the Registered Trade Mark " Protosil ", alternate washers 35, 36 of chamois leather and " Protosil" respectively, an anti-extrusion washer 37 of polytetrafluorethylene, and a steel washer 38. The washers 34, 35 and 36 are impregnated with a liquid polymer such as that known under the Registered Trade Mark, "Thiokol". An annular space 31 surrounding the piston 39 is connected by ducts 42, 43 with a groove 44, which together with the end cup 18 defines the reservoir R. The liquid in the reservoir R may be that classified as S.A.E. 140 and is pressurized by a spring-loaded piston 47, and is replenished at 49. The chamber A is charged with liquid of Specification D.T.D. 585, via a valve 14, to 7000 p.s.i. (under no load). The spring shown is for a vehicle suspension, and normal pressures under static and maximum dynamic loads are 11.000 p,s.i. and -15,000 p.s.i. respectively. A dustexcluder tube 21 bears on phosphor-bronze bushes 22, 23 and also serves as a guide for the plunger 19. Filters 25 act as breathers for an air space 26 (which has no resilient action). A plurality of springs may have a common reservoir R. According to the Provisional Specification, a number of radiating passages may lead between the groove 44 in the housing 30 and a small annular clearance-space surrounding the plunger. Also the space 31 is vented to atmosphere. Specifications 560,047 and 560,048, [both in Group XXXII], are referred to.

Abstract: 1,044,082. Filters. J. MULLER. Jan. 27, 1964 [March 4, 1963], No. 3393/64. Heading B1D. A filter composing filtering columns 1 and 2 each composed of a stack of rings provided on one or both faces with grooves through which the fluid passes is cleaned by a piston and a valve device acting under fluid pressure which forces fluid through the columns inthe direction opposite to that of normal flow. In the embodiment shown in Fig. 1 fluid to be filtered enters through passage 111 and during normal operation passes through entry 112, through filter columns 1 and 2, into space 99 and out through passage 100, bellows 119 maintaining fluid pressure in space 99. Fluid also passes past needle valve 21 into cylinder 101 to act upon piston 103 which moves downwardly under the pressure. There is lost motion in the coupling between rod 107 and the piston rod 109 but when the piston rod abuts a clevis 11 it moves a link 12 downwardly compressing spring 18 in the process. Unfiltered fluid in space 110 is displaced via chamber 115 and pipes 20 and 117 back to the supply tank. When the piston has moved beyond the point of alignment with link 106 the spring 18 acts to move the link 106 upwardly and so move the two valves 104 and 105. Consequently fluid passes through entry 113 into space 110 and acts a piston to force it upwards so forcing fluid past non return valve 120 and opening 123 into space 99 from where some fluid passes through columns 1 and 2 in direction opposite to that of normal flow. Residue is forced into chamber 114 and thence into a collecting vessel through pipe 116. The valves change position. When piston reaches the top of cylinder. The poppet valve mechanism may be replaced by a rotary plug valve. In the embodiment of Fig. 8 (not shown) are part 148 of the cylinder containing the piston is rotatable and incorporates a distributor with an opening 149 arranged to register successively with the openings in the columns 50 cleaning the columns one at a time without interrupting the filtering operation. A heated fluid may be passed between the walls 97 and 122 of the casing to reduce viscosity. The collecting vessel may be of the pressure type or gravity type, illustrated in Figs.9 and 10, (not shown).
