Abstract: 378,102. Crane control gear. COWANS, SHELDON, & CO., Ltd., KINDER, W. C., and BROADBENT, H., St. Nicholas Works, Carlisle. May 11, 1931, No. 13862. [Class 78 (v).] Control gear for the brake band and the coil clutch of the winding-drum of a crane comprises a pressure or vacuum pump and reservoir, two fluid-pressure cylinders with pistons operatively connected to the brake and clutch levers respectively, and control valves for connecting the cylinders with pressure or vacuum and with exhaust. As shown, an air reservoir 6 is charged to a constant pressure by a constantly running motor 7 and compressor 8. The reservoir is connected through valve 14 and pipe 13 to a cylinder for operating the brake ]ever, and through pipe 22 and valve 23 to a cylinder for operating the clutch lever. The levers are weighted to apply the brake and to engage the clutch. The brake valve 14 is controlled by a pedal 17, and the clutch valve 23 by a handlever 24 pivoted on the spindle of the crane motor controller 25. In the normal position of the control levers, the brake is held off by fluid pressure, and the fluid-pressure cylinder of the clutch control gear is open to exhaust so that the clutch is engaged. A hand brake-lever 29 moves a bell crank 29a which is connected with the weighted brake-lever by a slotted link, so that the brake may be operated independently of the pedal control.

Title: Improvements in or relating to pneumatic tyres, including their air tubes, and theirwheels, and the fitment of same to existing chassis hubs
IPC: B60C3/04
Filed: 1927-05-23
Abstract: 300,999. Killen, E. B. May 23, 1927. Jackets and covers; air-tubes.- A low-pressure pneumatic tyre is constructed with an oval-section cord foundation and tread and an over-all width greater than the centre-line height, these dimensions being respectively greater than, and less than, those of an ordinary highpressure tyre of similar load-carrying capacity, with short side-walls 31, and with base-beads 12 abnormally wide-apart but of less over-all width than the side walls. In cross-section, the curved tread may comprise 20 per cent to 50 per cent of the total centre-line height of the cover, and the inner cord foundation forms the minor arc of a circle 30 which may extend beyond the wheel-centre. The air-tube 26 is also of oval-section and may be so shaped that, before inflation, it can be assembled clear of the rim and the inner-tread portion of the cover. A protective liner 24, Fig. 1, 23, Fig. 7, of rubber &c., with or without a cord reinforcement, and also of oval-shape in cross-section, may be fitted between the air-tube and cover. In all cases, the tyre comprises three tread widths 19, 20, 21, and projecting-ribs 22; and may replace a low-pressure tyre of similar width and tread-diameter but of greater centre-line height. Fig. 1 shows a single pneumatic tyre constructed to replace twin solid tyres 4, 4, Fig. 2, of the same load-carrying capacity and of the same tread diameter but mounted on a wheel-rim of smaller diameter. Fig. 7 shows the tyre constructed to replace a larger-diameter, narrower, high-pressure, tyre 3 (shown in broken lines) as used on a rim which is narrower but of the same diameter as that used for the wider low-pressure tyre. Fig. 11 shows a single low-pressure tyre as constructed to replace twin high-pressure tyres 3, Fig. 12, of similar tread and rim-seating diameters. Fig. 14 illustrates the adaptation of one wheel-rim fitment for tyres of different widths and heights to carry different loads. Specifications 209,123, 235,971 and 280,669 are referred to.

Abstract: 790,436. Purifying liquids. ESSO RESEARCH & ENGINEERING CO. May 8, 1956 [May 13, 1955], No. 13881/55. Class 46. A tower 1 of the type used in successive mixing and separation ol two partially miscible liquids of different densities, contains at least one tray assembly comprising a plate 7 extending across the major portion of the width of the tower and having a downwardly extending plate 16 at its edge, a minor portion of the plate 7 being perforated with holes 8. The holes 8 are enclosed above the plate 7 by a chamber 9 having a downward outlet 10 on the side of the chamber away from the gap 14 between the plate 7 and the tower 1. A plate 19 extends from the top of the tower downwards between the outlet side of the chamber 9 and the tower. Light liquid entering at 2 passes into the chamber 9 through the holes 8 and then through the outlet 10 where it mixes with the heavy liquid entering at 3. Separation takes place in the space 11 and the light liquid is removed through outlet 13 and the heavy liquid through outlet 12. A split baffle may be fitted below the plate 7 to smooth the flow to the holes 8 and the top plate 17 of the outlet 10 may be shaped with a toothed edge with upwardly turned tabs between the teeth. When a plurality of tray assemblies are used, adjacent trays are arranged in reverse relationship so that the gap 14 between the tray and the tower is on opposite sides of the tower for adjacent trays.

Title: Separation of hydrohalic acids
IPC: C01B7/19
Filed: 1956-05-07
Abstract: Hydrofluoric acid is eliminated from an aqueous solution containing at least one other hydrohalic acid, e.g. hydrochloric acid, by contacting the solution with a small amount of alpha alumina obtained by calcination, which is substantially insoluble in the concentrated hydrochloric acid solution and which retains its porosity in such manner as to fix the hydrofluoric acid, and separating the hydrochloric acid.  The alumina, which should be in particulate form, may be obtained by calcining at 1000-1200 DEG  C. hydrargillite, or other hydrated alumina, alumina gel, or amorphous alumina.  The absorption of the HF on the alumina is non-reversible.  Aqueous HCl, preferably concentrated, e.g. 300-450 grms./litre, containing HF, may be passed continuously through a moving bed of alumina from bottom to top, while alumina is fed in at the top and withdrawn from the bottom, or may be passed through a fixed bed of alumina, or series of such beds, one of which is replaced as required, or the alumina may be dispersed in the solution by agitation and separated.  The hydrochloric acid may be washed out of the alumina, and the alumina dried.  Before drying, the washed alumina may be neutralized with caustic soda or sodium carbonate when a mixture of sodium and aluminium fluorides is formed.  The solution treated may be obtained in the manufacture of fluorinated compounds by treating chlorinated compounds with HF.
