Abstract: 101,440. Hasselt, R. van. March 21, 1916. Alkalies and chlorine, obtaining; electrolytes, circulating and treating non-chemically; diaphragms. -A strong alkali-chloride solution enters an anode compartment just above an horizontal diaphragm 6, Fig. 1, say by a pipe 8, leaves at a higher level by a pipe 16, and passes to a chamber where it is heated to expel chlorine and resaturated with salt, after which it returns to the anode compartment. Circulation may be maintained by a pump. In cne arrangement, the regenerating-chamber 3, shown in horizontal section in Fig. 3, contains heating-coils 15 below a grating 14 supporting the salt. The liquid flows downwards through the chamber, and chlorine escapes through a pipe in the lid. Any additional solution required is supplied to the electrolyte after this has left the chamber. The composition of the electrolyte may be adjusted by regulating the composition of the 1'resh solution. In another arrangement, one compartment of the regenerator contains a heating-coil 18, Fig. 5, while another contains a perforated salt receptacle 23 above a filter 25, a passage between the compartments being arranged so that the liquid flows downwards through both. In this case, impure salt obtained by evaporation of the alkali may be employed, any precipitate being retained by the filter. The additional liquid is preferably passed into the second compartment above the filter. Alkali from the salt or from the cell, and hypochlorite, may be decomposed by hydrochloric acid. From either form of regenerator, the electrolyte flows to a vertical pipe 9, Fig. 1, open at its upper end and contained in a vessel 2 covered by a glass bell 10. An aerometer and thermometer may be arranged in this vessel. Several cells may be connected to one regenerator. The electrolytic diaphragm may be thick and homogeneous, to prevent increase of diffusion in consequence of the movement of electrolyte; or a thin diaphragm may be protected by a layer of coarse-grained material. A sight-glass may be provided to indicate the level in the cell, or the outlet pipe 16 may be of glass

Title: Multi-path radiation beam analyser
Inventor: CAULTON GRAHAM KENNETH
IPC: G01J3/42
Filed: 1964-01-31
Abstract: 1,088,721. Measuring spectral content photo-electrically. UNITED POWER CO. Ltd. April 30, 1965 [Jan.31, 1964], No.4333/64. Heading G1A. In a multi-path beam analyzer in which radiation is diverted along a plurality of optical paths each including a filter having known radiation filtering characteristics and the emergent beams from the paths are recombined for application to a single detector the diversion of the testing radiation is effected by an optical element the position of which is controlled by a galvanometer movement. The optical element may comprise a plane mirror or a lens and may be disposed in a central position between two filters to which the radiation may alternately be diverted by a square waveform applied to the galvanometer. The resultant beams of wavelengths selected by the filters may be reflected by a concave mirror on to a common detector. The radiation may be admitted through a central hole in the concave mirror and the filters may be in the path of beams reflected to the concave mirror by a pair of plane mirrors at right angles. The galvanometer may be energized by a train of modulated pulses the phase of adjacent groups of which are reversed in order that the beams from the two paths may be separated in the detector output. A mask may be introduced to obstruct the beams over a central range of diversions so that a series of pulses are produced by the detector, the heights of successive groups of pulses give an indication of the instantaneous amplitudes corresponding to the different wavelengths. In further arrangements described with reference to Figs. 10a-c (not shown), a lens, or lenses, are used in place of a concave mirror, a pair of spaced lenses with the two filters between them and with the optical element and detector beyond the lenses at each end being used in one case, and a single lens with the optical element and the detector element on the same or on opposite sides of the lens in the other. A practical embodiment is described with reference to Fig. 1-5 of the complete Specification and its use in determining the ratio of two different wavelengths radiated by a hot body as a means of measuring the temperature of the body is referred to. The measuring circuit provides two outputs one of which is held constant by a feedback loop and the other of which in consequence provides a direct temperature reading.

Abstract: 1434631 Separating hydrocarbons by adsorption BRITISH PETROLEUM CO Ltd 29 Jan 1974 [30 Jan 1973] 4575/73 Heading C5E [Also in Divisions B1-B2] In a cyclic process for separating n-paraffins from admixture with branched and/or cyclic hydrocarbons using two or more beds of 5 A molecular sieve in stages of adsorption and desorption, the quantity of feed to the sieve in the adsorption stage is reduced by maintaining the feed rate constant and reducing the duration of the adsorption as the operating capacity of the sieve decays in succeeding cycles. The overall cycle time for each bed can either be reduced, or maintained constant by increasing the duration of the desorption and/or purge stages or by introducing a " dead time " into the cycle. If the feed is kerosene or gas oil the adsorption stage can be continued until the breakthrough point is reached and can be terminated when the composition of the effluent is the same as that of the feed. If the feed is gasoline the adsorption stage is terminated before the breakthrough point is reached. The examples relate to processes in which a system of 6 beds (each in different stages of decay) is fed continuously to produce a continuous product stream; each bed is taken out of use in sequence when its capacity has fallen to 80 to 50% of that of the fresh sieve and regenerated. The purge and desorption can be accomplished by displacement or pressure reduction.

Abstract: 824,397. Road vehicle spring suspensions. FIRESTONE TIRE & RUBBER CO. Feb. 12, 1957 [Feb. 13, 1956], No. 4751/57. Class 108(2) [Also in Group XXIX] A control device 10 for a vehicle pneumatic suspension system comprises a housing 11 having a hollow interior for the passage of air under pressure therethrough, valves 72, 78 within the housing normally blocking passage of air through the hollow interior, a shaft 25 extending transversely through the housing, an actuating bar 100 affixed at one end to the shaft 25 and extending longitudinally of the housing and between the valves, and hydraulic means affixed at the other end of the bar 100 to damp movement of the bar towards the valves when the shaft 25 is rotated. In the example a bellows type air spring 12 is connected through a pipe 33 to the control device 10 which is connected to a source of air under pressure by a pipe 32. The control device 10 is mounted on a longitudinal frame member 16 of the vehicle, and a valve actuating spring 24 fixed at one end to the shaft 25 has a sliding connection at its other end with a stub flange 19 mounted on a differential housing 20. Increase in vehicle loading causes clockwise rotation of spring 24 and shaft 25 so as to open valve 78 to allow air under pressure to flow through the valve and housing 10 to the air spring 12 until the vehicle frame is restored to its original height. Similarly, decreased loading of the vehicle causes anti-clockwise rotation of spring 24 and shaft 25, thereby opening valve 72 to permit the escape of air from the spring 12. Rotation of shaft 25 in both directions is resisted by the hydraulic damping means comprising a piston 92 connected as shown with the bar 100. The piston 92 has a small orifice 96 and a piston rod 91 which is loosely guided in a bore 90 in a plug 87. A well 89 in the plug 87 contains excess fluid to compensate for the area of the piston rod 91.
