Title: Process and arrangement for the recovery of gases or vapours by means of solid adsorbent substances with recovery of heat units
IPC: B01D53/04
Filed: 1932-07-26
Abstract: <PICT:0398010/III/1> In a process for recovering gases or vapours by means of a solid adsorbent the gas mixture containing the substances to be adsorbed and recovered is passed through a non-adsorbent heat-accumulating mass and thence through the adsorbent, whereafter steam is passed in the opposite direction through the adsorbent and the heat-accumulator to expel the adsorbed substances and the adsorbent is dried by air or gas passed through the heat-accumulator and the adsorbent in the original direction.  The Figure shows one arrangement of apparatus in which the heat accumulating mass A, supported by a grating 13, is arranged immediately below the adsorbent B supported on a grating 2.  The mass A may comprise, for example, pieces of flint or quartz, or a block of metal or cement traversed by channels, or a tube-nest with plain or ribbed tubes, filled with solid or fluid bodies such as solutions of salts having a high heat of crystallization, diluted, saturated or supersaturated solutions, or alloys of suitable specific heat or latent heat of fusion.  The mass B may comprise, for example, active carbon or granulated silica gel. In the adsorption stage the gas mixture containing the substances to be adsorbed is admitted through the opening 1 and passes through the grating 13, mass A, grating 2, mass B and grating 2<1> to a flue or suction outlet 3, the substances to be recovered being retained in the mass B.  For the extraction stage the supply of the gas mixture is shut off and saturated or superheated steam is admitted through a pipe 4.  This heats the mass B and carries off the adsorbed substances through the mass A to an opening 5 communicating with a condenser, separator and collecting vessel.  For the drying stage the steam supply is shut off, the opening 5 is closed, and air or another drying gas is admitted through the opening 1.  This passes through the masses A and B and carries off the adsorbed moisture through the flue or opening 3.  The drying gas may be the original gas mixture before or after it has been freed from its adsorbable constituents.  For the cooling stage the supply of cold air may be continued or the mass A may be sprayed with cold water from a pipe 7.  In a modified arrangement the mass B is contained in an annular cage surrounding a vessel containing the mass A.  A number of units of apparatus, each comprising an adsorbent mass and a heat-accumulator mass, may be connected in series or in parallel.
Patent GB-516091-A (GB)
Title: Improvements in or relating to fluid pressure remote control systems
IPC: F15B13/01
Filed: 1938-07-15
Abstract: 516,091. Hydraulic transmission of power. AUTOMOTIVE PRODUCTS CO., Ltd., and BEESTON, J. P. July 15, 1938, No. 21071. [Class 69 (ii)] In fluid pressure remote control systems in which a reversible flow pump or transmitter unit is connected by a pair of pipe lines with a double acting slave unit therein, fluid under pressure is forced into one of the pipe lines to move the. slave unit, the other pipe line returning the fluid from the slave unit. A valve device checks the return flow so that the rate of movement of the slave unit is restricted by a force other than through the working liquid. The valve device is spring closed but tends to be opened by the return liquid from the slave unit, the opening being assisted by the pressure of liquid in the pipe line. As shown, a valve device is provided with a pair of passages 11, 12 joined by connections 13, 14 respectively to the working spaces of a double-acting slave cylinder 15 and controlled by ball valves 20, 21, against which bear piston-like intermediate members 24, 25. The latter members are provided with channels 37 bringing recesses 38 into communication with passages 39, 40 leading to pipe lines 41, 42. The pipe lines are connected to a transmitter device comprising a pump 43, reservoir 44 and reversible selector valve 45. Non-return ball valves 48, 49 act in theopposite sense to valves 20, 21 so as to serve as by-passes. When pressure liquid is fed through pipe line 42 to move piston rod 53 of slave unit 15 downwardly the liquid opens the valve 49 and passes through passage 11 and connection 13 to upper working space of unit 15. The liquid pressure thus creates enough force to open the valve 20. If the piston rod 53 tends to move upwardly the corresponding liquid pressure in the connection 13 is unable to force either of valves 49, 21 open until reinforced by the pressure from pipe line 41. A modification of valve device operates in one direction only. The valve device may be employed in a flowequalizing system such as is described in Specification 496,550.
