Abstract: 1,163,006. Purifying hydrogen. METALLGESELLSCHAFT A.G. and LINDE A.G. 15 Nov., 1966 [15 Nov., 1965], No. 51208/66. Heading B1L. [Also in Divisions Cl and C5] Hydrogen is obtained from gas mixtures derived from cracking liquid or gaseous hydrocarbons under a pressure of not less than 40 atmos. abs., which are rich in H 2  and CO but contain sulphur impurities, by means of a preliminary scrubbing with an organic polar solvent (e.g. methanol or acetone) at ambient temperature, to remove acid impurities, followed by the catalytic conversion of CO with steam to yield more H 2  and CO 2 , after which the effluent is again scrubbed at a temperature below the carbon dioxide dew point of the converted high pressure gas, residual CO, CH 4 , O 2  and A being finally removed e.g. by a N 2  wash. The same scrubbing agent is used in both scrubbing stages, and is first conducted first through the second scrubbing stage for removal of C0 2  by condensation and then deprived of its CO 2  content by decompression and, optionally, by application of heat; after having being suitably heated, the agent is conducted through the first scrubbing stage and is finally regenerated by decompression and boiling to remove sulphur compounds.

Title: Apparatus for the rapid meausring of the angular dependence of light scattered from a scattering volume containing particles
IPC: G01N15/02
Filed: 1973-11-05
Abstract: 1405682 Photo-electric measurement of scattering GES FUER KERNFORSCHUNG mbH 5 Nov 1973 [9 Nov 1972] 51259/73 Heading G1A To determine the angular dependence of the amplitude of light scattered from a jet of particles a laser beam is directed into the jet and scattered light passes via a fixed slit to a fixed detector; either the laser beam or the field of view of the detector is scanned around the jet so as to measure the amount of scattering at different angles around the jet. In Fig. 1 the jet is shown at 3 and light from a laser 7 passes into it via a prism 8, quarter wave plate 9, prism 10, polarizer 11 and ellipse segment 4. The prism 5 is at one focus of the ellipse, and the jet is at the other focus so that as the prism rotates the light continues to strike the jet but rotates around it. The polarizing components prevent the light from varying in polarization or amplitude as it rotates, though such effects can also be minimized by using an ellipse of low eccentricity or can be allowed for mathematically. After passage through the jet the light is absorbed at 15. The scattered light reaches detector 18 via slit 16. In a second embodiment, Fig. 2, the laser light beam 21 strikes the jet at a fixed angle, and a rotating mirror 5 is used to scan the field of view around the jet. The laser beam is absorbed by a body 23 in this case, and the volume of the jet examined is determined by slits 27, 28. In a third embodiment, Fig. 3, the ellipse is replaced by two conical prisms 30, 31 having central bores. The laser light passes along the line 7 to a motor rotated prism 10 and thence along path 13 to the outer wall of prism 30; it is reflected upwards to prism 31 and then inwardly to pass through the jet. The scattered light reaches detector 18 via slit 16, an absorber 48 being positioned opposite the slit to collect laser and scattered light. This embodiment may be modified so that the detector is scanned rather than the laser beam. Assuming significant centrifugal force is avoided it is possible to scan the laser beam by physically rotating the whole laser around the jet instead of using the elliptical or prism reflectors.

Title: Double aperture technique for detecting station identifying signal in a time division multiple access satellite communication system
IPC: H04B7/212
Filed: 1967-11-13
Abstract: 1,210,404. Radio signalling. COMMUNICATIONS SATELLITE CORP. 13 Nov., 1967 [17 Nov., 1966], No. 51497/67. Heading H4L. In a time division multiple access system earth stations communicate via an orbital relay satellite, each of said stations being allocated a part of the satellites time frame and given a unique identification signal. When a station is operating it detects its own identification signal in the satellite time frame and verification is obtained by also detecting the identification signal of a designated master station and forming from it a time gate for the said station's identification signal. As described, the demodulated signals received at a slave station from a satellite relay station are applied both to a detector 10 for the station's own identification signal and to a detector 30 for a master station's identification signal. The detector 30 sets a flip-flop 29, which activates one input of an AND gate 33, whose other input receives pulses from a station clock. Output from the gate 33 drives a delay counter 32 which, after a time which is approximately equal to the known time between the master station's and the slave station's identification signals, sets a flip-flop 38, which activates a first input 40 of an AND gate 18. A second input 28 of the gate 18 is activated from the output of the detector 10 via a similar arrangement to that connected between the detector 30 and the first input 40 of the gate 18, but in this case a delay counter 20 sets a flip-flop 26 after a time which is approximately equal to one time frame. A third and final input 17 of the gate 18 is connected directly to the output of the detector 10. When all three inputs of the gate 18 are activated it gives an output. The various flip-flops are reset by second outputs from the delay counters, given at suitable time intervals after their first outputs.

The dyes may be obtained as described in Specifications 927,774 and 929,398.  A number of dyes are specified of the monoazo, disazo, dioxazine, nitro, xanthene, anthraquinone and phthalocyanine series.ALSO:Textile materials of natural or regenerated cellulose, silk, cellulose acetate of triacetate, polyesters, acrylic polymers, polyamides or polyolefins are dyed by impregnating with an aqueous solution of a dye of the formula:-  R-[SSO3M]n wherein R includes the chromophone group and may contain other water-solubilizing groups, M is H, NH4 or a metal and n is 1-4, which dyes are then converted to an insoluble form by treatment with an alkali metal chlorite in the presence of water at a pH not greater than 5 and heating to at least 60 DEG C.  The dyes may be derived from the azo, anthraquinone, vat, acridone, phenazine, oxazine, dioxazine, di- and triphenylmethane, nitro and phthalocyamine (which may contain a metal) series; a number of dyes are specified - the thiosulphuric acid groups may be attached direct to an aromatic nucleus of the chromophone or via an aliphatic or aromatic bridge which may contain hetero atoms.  It is convenient to use a single stable dyebath containing both the dye and the chlorite for the impregnation below 60 DEG C and then heat the material to 60 -120 DEG C or higher.  The present process may be combined with a finishing process by (a) applying the dye and chlorite from one or two baths, drying, applying the finishing agent and heating or (b) as in (a) but heating to insolubilise the dye prior to applying the finishing agent.  A number of suitable finishing agents are listed the preferred one being formaldehyde which is employed with a catalyst (preferably a metal salt which is a lewis acid in the solid state) to cross-link cellulose materials.  Examples are given.
