Title: Improvements in or relating to the separation of the constituents of gaseous mixtures containing hydrogen
IPC: F25J3/06
Filed: 1923-03-15
Abstract: 195,950. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. April 4, 1922, [Convention date]. Separating gaseous mixtures by liquefaction.- A process for the separation by partial liquefaction of mixtures containing hydrogen, such as water, illuminating, or coke-oven gas, comprises the vaporization of the liquefied portion at a pressure above atmospheric, and the expansion with external work of the gaseous product, the refrigerative effect of the expansion producing liquefaction at a temperature below the vaporization temperature; the hydrogen thus obtained may be expanded without external work. In the apparatus, intended for water gas, shown in Fig. 1, the gas dried and freed from carbon dioxide and sulphur compounds is admitted to the outer part of the heat-exchange column E wherein other solidifiable constituents are extracted as liescribed in Specification 195,598, and passes thence through pipe B into collector C wherein it ascends the pipes F under pressure and is partly liquefied. The liquid formed is passed through a valve G to the space D wherein it is partly evaporated, the vapour being expanded to atmospheric pressure in the motor 0, either directly or after passage through the coil S<1> around the exchanger E. The expanded and partly liquefied products pass into the space I around the tubes F, further cooling and purifying the gases rising therein; they finally pass through pipe N into the exchanger E. The gas reaching the top of the tubes F consists of hydrogen and is expanded at the point L into the space J around the top of the tubes, finally passing through pipe X to the exchanger. The expansion at the point L may be without external work, or a further expansion may be effected with work during the passage to the exchanger. Fig. 2 shows a modified apparatus intended for illuminating or coke-oven gas, comprising two sets of tubes F, F' in a column, the lower set receiving gas from an exchanger as in Fig. 1. The liquid formed in the lower tubes is delivered through valve G to the lowest compartment surrounding the upper tubes and thence to the space around the lower set, the evaporate from which passes through an expansion-engine O through the space I around the tubes F<1> to the exchanger. The liquid formed in the upper tubes is received in a vessel P and delivered through the third compartment around the upper tubes to the exchanger; the gases from this third compartment may be expanded in a motor. The final expansion of the hydrogen escaping at the top is effected without work at the point L, or it may be effected without work at the point L and with work in the pipe X. The expansion of the hydrogen may be dispensed with, or an additional cooling effect may be obtained by adding to the gas before its expansion at the point L a supply of cold compressed hydrogen or nitrogen. Specification 175,605 is referred to.

Filed: 1935-03-18
Abstract: 454,016. Machines for working land ; rollers. McGUIRE, J., 11, Coppice Grange, Saughall Massie, Wirral, Cheshire. March 18, 1935, No. 8320. [Class 6 (i)] A machine for punching or piercing turf &c. is provided with turf-piercing spikes which are pivotally connected to a carrier or conveyer mounted on a carriage or wheelable frame and are moved, during the travelling of the machine, in an endless path relatively to the frame so that the head of each spike engaging the ground has components of movement perpendicular to the ground, for penetration of the spikes into the ground and withdrawal therefrom, and a component of movement relative to the frame and parallel to the ground approximately equal in average velocity and opposite in direction to the movement of the frame along the ground. The heads of the spikes may move in trochoidal paths of curtate cycloidal type and the spikes engage the turf &c. during the movements of their heads round the nodes or loops of their trochoidal paths. The wheelable frame may be supported on rollers 12 and castor wheels 13. A subframe 14 is pivoted on the roller axle 15 and adjustably supported by detents 16 engaging notched quadrants 19, the detents being mounted on propelling shafts or handles 22. The spikes 29 are pivoted on spindles 28 in a skeleton drum 23 mounted on the sub-frame 14 and driven from the roller axle 15 at a greater peripheral speed than the rollers 12. The driving gearing and the ratio of the effective radius of the drum to that of the rollers 12 are such that while a spike is in engagement with the ground it has very little or no resultant movement in the horizontal direction. The spikes may be vertical while in engagement with the ground ; or the angle at which a spike enters the ground may be governed by metal strips or rods 40 which may be fixed or adjustable. The spikes may be fixed on rotatably mounted spindles or on cranked strips pivoted on the drum 23. Arms for traversing or guiding the machine may be connected directly to the main frame, and the machine may be drawn by horses or provided with a driving motor. A formula is given connecting together approximate values for the radius of the rollers 12, the effective radius of the drum 23, the depth of penetration of the spikes, and the ratio of the angular speeds of the rollers and drum. In modifications, the spikes may be carried by lever arms radiating from a common shaft or by spiders secured on a common shaft. In other modifications, the spikes may be mounted on flexible endless conveyers moving in circular or approximately elliptical paths.
