Abstract: 169,099. Entwisle, E. J. Sept. 20, 1920. No Patent granted (Sealing fee not paid). Shedding - motions.- In looms for weaving coir yarn fabrics for door mats, the usual positively - operated tappet-lever 2, Fig. 1, operates the pile-warp harness during the formation of the pile loops by means of a stud 5 engaged by a spring-controlled bearing-lever 8 pivoted to a link 7, connected to levers 16, 17, which are connected to the pile-warp harness. After a mat has been woven and when weaving the divisions between the mats, a normally stationary shaft 28, Figs. 1 and 4, is rotated and a cam 29 thereon actuates a spring-controlled rod 27 and duck-bill lever 24 which disengages the lever 8 from the stud so that this moves idly in slots in the link 7, which is held in its lowest position bv the engagement of the lever 24 with an inclined face 11 of the link, the pile warp harness consequently remaining stationary so that simple fabrio is woven in the division between the mats. The shaft 28 is provided with a disc 33 carrying a spring-controlled dog clutch 31, which is normally held out of the path of lugs 42 on a wheel 41 driven from the usual tappet shaft 39 by the engagement of a lever 43 with a projecting peg &c. 32 on the clutch, such lever being normally held in the position shown by a weighted locking- lever 46. After the required time, the lever 46 is engaged by a stud 55 on a chain 54 passing round a sprocket-wheel on a shaft driven. by ratchet and cam gearing from the shaft 39. The lever 46 is thus disengaged from the lever 43. which then allows the clutch to rise and be engaged by one of the lugs 42, so that the shaft 28 is rotated and causes the shedding of the pilewarp harness to be arrested, as described above. The chain 54 passes over a sprocket wheel 56, the position of which is adjustable to accommodate different lengths of chain.

Abstract: 650,017. Gas-turbine plant. LUCAS, Ltd., J. Oct. 15, 1948, No. 26855. [Class 110(iii)] [Also in Group XXIX] The output of a variable-delivery liquid fuel pump suitable for use with jet-propulsion engines is controlled by a servomechanism itself controlled by a valve actuated by a member responsive to atmospheric and blower air pressure, and blower air is admitted to the chamber associated with the pressure responsive member past a spring-loaded valve whilst the atmosphere has access to the chamber past a restriction. In an embodiment, the pump comprises a rotatable block i provided with plungers g, the stroke of the latter being set by a swash plate e which is adjusted in position by a servo-piston b. The piston is subject on its left-hand side to the outlet pressure of the pump and this pressure leaks to the right-hand side through a restriction m. The right-hand side of the piston has a variable vent controlled by a valve o carried on a lever, the latter being loaded by an evacuated capsule p, piston, or diaphragm, and a thrust rod t acted upon by the loading-spring c of the servo-piston. Capsule p is acted upon by atmospheric pressure which is led into the chamber containing the capsule past a restriction u, and when the blower pressure exceeds a predetermined value, it forces open a ball valve v and can then also act on the capsule Valve o may be substituted by a piston type valve situated between the capsule and the servo-piston loading spring c. In parallel with valve o is a further hinged valve 5 which is acted upon by a diaphragm 6 to give a control of the pump according to the speed thereof.

Filed: 1963-07-08
Abstract: 989,866. Concentrating liquids by freezing. H. H. CLARK, and B. C. BRIGGS. July 8, 1963, No. 26912/63. Heading F4H. In a process for freezing out water from a liquid the liquid is introduced into a continuous stream of a cooled, water-immiscible carrier liquid. As shown in Fig. 1 the liquid, e.g. spent sulphite liquor, brine or fruit juice, is supplied through a line 8, pre-cooler 9 and line 10 to a spray assembly 12 at the top of a freezing vessel 1. A cooled carrier liquid, e.g. kerosene, is also introduced into the vessel 1 via a manifold 18 and apertures 20 at a substantially greater rate than that of the liquid from spray 12, so that the latter becomes dispersed in and partially frozen by the carrier liquid. The bottom of the vessel 1 is disposed in a tank 21 immediately above a wire-mesh conveyer 22 which retains the ice-crystals and mother liquor while permitting the passage of carrier liquid, the latter being withdrawn from the tank by a pump 32, cooled in the evaporator 62 of a refrigerative system and recirculated to the vessel 1 through line 16. The ice and mother liquor are conveyed to a centrifuge 37 which discharges liquor and any entrained carrier liquid to a separator 52, the carrier liquid being supplied by a pump 54 to pump 32 and the mother liquor being recirculated to spray 12 through line 58. The ice from the centrifuge is digested with water from a spray ring 40 to form a slurry which is forwarded through a line 44 to a valve 45 and thence either to the precooler 9 or to a line 48. Well water from the pre-cooler may be recirculated to the spray 40 via a line 50, the remainder passing through the line 48 to cool the condenser 49 of the refrigerating system. The heated water then passes through a line 63 to a heat exchanger 60 which is used to heat mother liquor from separator 52 to reduce the viscosity of the liquor which is discharged, together with liquor drawn off from the tank 21 through line 34, through a line 36. The water is discharged at 64. In the modification of Fig. 6 (not shown) the tank 21 and conveyer 22 are omitted and the carrier liquid is extracted from the vessel 1 through circumferential outlets while the ice and mother liquor continue to move downwardly to an axial outlet.
