Abstract: 621,952. Fluid-actuated valves. METAL VENTS, Ltd., and ZWICKY, J, F. Nov. 15, 1945, No. 30651. [Class 135] [Also in Group XXX] In load-handling apparatus wherein a pivotally-mounted skip is returned to its loading position from a tipping position by fluid-pressure apparatus (see Group XXX), a valve is provided for controlling fluid-supply to pipes 18, 19 Fig. 5, leading to opposite ends of the operating cylinder, comprises a piston body 24a slidable in a casing 25a, furnished with plugs 26, 27 and with ports 28, 29a, 38, for connection with the pipes 18, 19 and a drain pipe 39 leading to a reservoir. To effect return of the skip, fluid-pressure of sufficient value is introduced to a port 30 in the plug 27 to force the body 24a back against the action of a spring 32a until its port 40 registers with the port 28, its port 31a simultaneously registering with the port 38. Thus one end of the operating cylinder is supplied with fluid and the other end is connected with the drain pipe 39, whereby the piston in the operating cylinder is moved to effect return of the skip. The skip is tipped to its unloading position by gravity, and to permit this movement fluid at a reduced pressure is supplied to the port 30, whereby the body 24a is forced back until the port 31a registers with the ports 28, 29a so as to connect the pipes 18, 19. The supply of pressure to the port 30 is controlled by a manually operable three-way valve. In a modification in which the tipping of the skip is also effected by fluid-pressure, the valve casing 25b, Fig. 7, is provided with ports 49, 50 ; 52, 51 communicating respectively with a drain pipe 39a, pipes 46, 47 leading to one end of the operating cylinder and with a pipe 48 leading to the other end. To effect tipping, a predetermined low pressure is applied to the port 30 to move the valve piston 24b until its port 40a registers with the port 50 and its port 31b connects the ports 51, 49, whereby fluid pressure is supplied to one end of the cylinder and the other end is relieved of pressure. To return the skip, a predetermined high pressure is applied to the port 30 so as to move the valve piston 24b to a position in which the port 40a aligns with the port 51 and port 31b connects ports 52, 49. Specification 621,974 is referred to. The Provisional Specification refers to Specification 564,157, [Group XXX].

Abstract: Sulphur is produced by mixing gases or vapours containing hydrogen sulphide with the requisite amount of air, oxygen, or free oxygen-containing gas in the combustion chamber of an internal combustion engine, e.g. piston engine or gas turbine, and effecting combustion of the H2S therein.  Liquid and vaporous sulphur is discharged with the exhaust gases, and separated.  The H2S gas may also contain ammonia, carbon dioxide, or hydrocyanic acid.  The exhaust gases may be directly or indirectly cooled, or sprayed with liquid sulphur, or water, in a boiler to produce steam.  In an example a mixture of H2S and CO2 is burnt with air in a 30 H.P. Diesel engine.  The engine may have a hot spot of aluminium, aluminium alloy, or graphite, and piston rings of stainless or alloy steel, or aluminium alloy, e.g. aluminium-silicon alloy.  The engine cylinder is cooled by a cooling jacket at 120 DEG  C., and the piston and rings may also be cooled.  The exhaust gases at 470 DEG  C. are cooled to 250 DEG  C. in a water spray boiler, when liquid sulphur separates, and the remaining sulphur is washed out with liquid sulphur.

Abstract: 900,229. Spin echo data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 15, 1959 [Dec. 15, 1958], No. 31498/59. Class 106 (1). [Also in Group XL (b)] A resonant cavity for spin echo storage apparatus is designed to support two different modes whereby output pulses may be derived from the cavity in a mode orthogonal to that of the input pulses. As shown in Fig. 1a, two orthogonally disposed rectangular waveguides 6, 7 are coupled by irises 3, 4 to a shallow cavity 5 of square section which is capable of supporting TE 021  and TE 012  modes. The two modes are coupled by the precession of spinning electrons in a chemical sample 8, information and read-out pulses being fed at the processional Larmor frequency of the sample through waveguide 6 and spin-echo pulses being derived in an orthogonal mode through waveguide 7. The cavity may be tuned by screws 9. The two waveguides may extend in the same direction. In the modification of Fig. 3a, the cavity is coupled to pairs of waveguides 12, 13 and 14, 15 by pairs of irises 11a 11b and 16a, 16b. The waveguides form the arms of two magic-T junctions. In a further modification, Fig. 4b, the input and output are fed by means of coaxial lines to a pair of half-wavelength strip lines 20, 21 arranged to cross at right-angles. The sample 22 is placed at the common centre of the lines. Cavities of circular section with central irises may be used (Fig. 5, not shown). These are coupled to rectangular waveguides arranged either with their longitudinal axes or their cross-sections at right-angles to each other. The depth b of the cavity is made small in order to obtain a Q value of less than 100. Specification 795,057 is referred to.
