Abstract: 562,875. Shaping drum-built tyre bands into tyre form. STEVENS, A. H., (Firestone Tire & Rubber Co.). May 30, 1942, No. 21644/43. Divided out of 662,712. [Class 87 (ii)] The margins of the band are sealed between the stationary upper head 66 and the movable, detachable lower head 34, Fig. 1, which rests on a hydraulic ram 28, and compressed axially between the two heads, and concurrently pressure fluid is introduced into the band to distend the middle thereof. The pressure in the band is then 75 lbs. per sq. inch. The pressure is then reduced to 40 lbs. and the ram is lowered slightly to the position shown in Fig. 13, to facilitate introduction of the core 61. The core is then lowered into the band and concurrently distended by carbon dioxide under pressure, the ultimate pressure therein being 65 lbs. The ram is again raised and the pressures in the band and core are increased, the former to 75 lbs. This completes the shaping. The pressures in the band and core are then released in a series of steps, the pressures being first decreased, then increased to a value less than the original, then decreased, then increased to a less extent, and so on, a pressure difference being maintained between the core and the band; this procedure eliminates wrinkles from the core. The pressure in the band is finally atmospheric, whereupon pressure is evacuated from the core, the heads are separated, and the band-core assembly removed. The apparatus shown is that described in Specification 562,712. Specification 419,244 also is referred to.

Abstract: 451,007. Draught - regulators for flues. DIFFUSION SOC. A R.L., 2, Rue Paul CÚzanne, Paris. July 31, 1935, No. 21719. Convention date, Aug. 4, 1934. [Class 51 (i)] An automatic regulator for controlling the draught in a flue having an air inlet opening comprises a check-draught damper 15 controlling the opening, a flue throttling damper 27 and a thermally responsive member supported within the flue whereby a movement of the member in response to a change in flue temperature imparts a combined rectilinear and rotary movement to the dampers. As shown in Fig. 6, a flue 3 has an air inlet branch 2 over which is detachably fixed by screws 6 a cover-like casting 5 provided with air inlets 8 and a central hub 7. A shaft 30 extends through a bore in the hub and is secured by a screw 13, Fig. 8, to a cap 10 fastened to the hub in a rotatably adjustable manner by screws 11. Two coiled bi-metallic strips 14, 26 are secured to the inner end of the shaft by means of a sleeve 18 and screws 17 and by means of screws 20, to a collar 21 slidably and rotatably mounted on the shaft and carrying the check-draught regulator 15 and a tubular casing 23 housing the bimetallic coils. The inner end of the casing 23 is closed by a cap 24 having a bore 25 which forms a bearing for the inner end of the shaft 30. Mounted on the casing by means of adjustable clamps 28 is a flue damper comprising two segments 27. If the flue temperature rises, the contraction of the coils 14, 26 draws the regulator 15 slightly away from the cover member 5 and simultaneously rotates the regulator 15 and damper 27 so as to admit more air to the flue and to throttle the passage of gases through the flue. The movement of the regulator 15 away from its seating prevents dirt or soot from causing the regulator to stick to the cover and thus prevent rotation. In a modified form, Fig. 8, a single bimetallic coil 26 is anchored by a sleeve 18 and screw 19 to a shaft 39 which extends through the hub and a bearing packed with graphite and is provided at its outer end with an adjusting knob for manual rotation. The bearing is fixed to or is integral with the rotary check draught damper which latter carries the flue damper segments 27.

Title: Improvements in or relating to gas purification
IPC: B01D53/14
Filed: 1959-06-25
Abstract: In the removal by solid sorbents of a trace gas from a carrier gas, the concentration of the former being so low that the sorptive capacity of the sorbent decreases more than proportionally with decreasing trace gas concentration, there is added prior to sorption of said trace gas (a) a further quantity of said trace gas or (b) a gas having similar sorbability to said trace gas or (c) an isotope of said trace gas, in such quantity that the sorptive capacity of the sorbent in relation to the mixture of trace gas and additional gas is proportional to the concentration of said mixture.  It is stated that the maximum degree of removal of trace gas may thus be increased. Several additional gases may if desired be added at different temperatures and pressures, but the added gas is preferably at the same temperature, pressure and humidity as the carrier gas.  The invention may be applied to reduce the concentration of traces of radioactive krypton and xenon in a mixture of helium and neon used as cooling gas in a nuclear reactor, using charcoal or silica gel adsorbent at a temperature of 80 DEG K by addition of inactive krypton and/or xenon.
