Patent GB-1379763-A (GB)
Title: Rotary reactor
IPC: C05B7/00
Filed: 1971-11-22
Abstract: 1379763 Granulating apparatus SOC ANON CROS 22 Nov 1971 [20 Nov 1970] 30831/74 Divided out of 1379761 Heading B5A [Also in Division B1] Apparatus for reacting liquid phase reactants on a moving bed of solid particles comprises (1) a tubular reaction vessel mounted for rotation about a longitudinal axis such that solid particles introduced near one end of the vessel will move through the vessel as it rotates; (2) a coulter or blade within the vessel and extending adjacent the inner tubular surface; (3) a conduit for introducing a first fluid into the vessel, the conduit being fixed rigidly to the coulter or blade and having an outlet adjacent thereto; (4) means for introducing a second fluid into the vessel. In operation, the coulter or blade maintains a groove or furrow in the moving particle bed as the vessel rotates, the first fluid issuing into the groove or furrow, which thus serves to prevent the conduit outlet from becoming blocked. The means for introducing the second fluid may also be a conduit fixed to the coulter or blade, or, e.g. spray means over the particle bed. More than one coulter or blade, with its associated conduit, may be present. Fig. 2 shows a rotary cylinder 2 in which fluid distributers 15, 17 are connected by flexible tubes 16, 18 to metal conduits 13, 14, welded on to coulter 12, the conduits being welded on the side opposite that where the solid particles strike the coulter. A fluid spray 19 is provided. The apparatus may be used in the reaction of H 2 SO 4  and NH 3 , or of H 3 PO 4  and NH 3  on moving beds of ammonium sulphate and ammonium phosphate respectively (see Specifications 1,379,762 and 1,379,761), and performs the functions of mixer, neutralizer, granulator and drier. A continuous process for making ammonium phosphate fertilizer is described.

Abstract: 767,357. Gas turbine plant. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 2, 1954, No. 31641/54. Class 110 (3). [Also in Groups XI and XXIX] Fuel under pressure is distributed to a plurality of vaporizing tubes 27 mounted in the annular combustion chamber of a gas turbine engine by a rotary valve comprising a cylinder 36 having a fuel inlet 24a and a plurality of calibrated identical orifices 37 connected to fuel tubes 26 leading to the vaporiz. ing tubes 27, and a cylindrical valve element 40 rotatably mounted in the cylinder 36 and having ports 41 calibrated similarly to and variably registering with the orifices 37. The valve element 40 is actuated by a diaphragm 43 mounted between the end of a chamber 34 communicating with the valve element 40 and a balancing chamber 44 communicating through a passage 50 and a flow restrictor 51 with one of the fuel tubes 26 at a point downstream of its calibrated orifice 37. A spring 49 is interposed between the diaphragm and an adjustable abutment carried by a wall of the balancing chamber 44. In operation an increase in fuel pressure to the rotary valve causes the diaphragm to rotate the valve element 40 to increase the flow areas of the calibrated orifices. Stops may be provided to limit the movement of the valve in both directions. Specification 760,173, [Group XXXV], is referred to.

Abstract: 604,095. Inductances. GUILLEMANT, R. E. Nov. 23, 1945, No. 31709. Convention date, Feb. 5, 1943. [Class 38 (ii)] A variable, high frequency, inductance with a movable magnetic core 4, comprises a coil divided into sections, each in a separate groove 2 of a former 1, the number of turns in each section being so selected as to give a predetermined relationship between displacement of the core and resonant frequency of the tuned circuit in which the inductance is connected. This relationship may be linear. The coils may be of enamel-covered stranded wire, and the grooves may be filled after winding with powdered magnetic material, some of this being removed as a factory adjustment in calibrating the inductance. The cores of two inductances in a superheterodyne receiver may be ganged for simultaneous movement, one inductance being in the high frequency circuit and the other in the heterodyne circuit. The latter may be in series with a similar smaller inductance, optionally with a magnetic core, and inductively coupled to an oscillation maintaining coil.

As disclosed, BCD digits at A 1 -D 1  ... A n -D n  are converted to 7- element form at 12 1  ... 12 n  to control such digit displays at 11 1  ... 11 n . Actuation of a test button at 105 causes display of "1" at each position, via a signal at 106, and if the test (see below) is successful, subsequent display of "2" at each position, via a signal at 107, another test being performed (see below). If either test shows error, display is inhibited by a signal from 108. The tests for "1" are done by logic circuits L 11  ... L 1n  and AND gate 103, and the tests for "2" are done by logic circuits L 21  ... L 2n  and AND gate 104. Each of these "logic circuits" ANDs a recognition of "1" or "2" (as the case may be) at the input with the AND or the NOR (respectively) of the signals controlling de-energization of the top and centre horizontal bars.

Abstract: 823,924. Valves. EXACTOR Ltd. Nov. 22, 1955 [Nov. 4, 1954], No. 32010/54. Class 135. An hydraulic control valve comprising a slidable member 2 in a housing 1 which also contains a non-return valve 11 and a relief valve 15 has supply and return connections 4, 5 for connecting to a pressure liquid circulating system, the connections 4, 5 opening from opposite sides of the housing into a recess 8 on the member 2 and the housing being flattened on either side to receive caps (not shown) by which it is connected to supply and return conduits or to enable a number of similar housings to be assembled together with their connections 4, 5 in alignment to form part of the circulating system in which case the outer housings only are fitted with caps. Pressure liquid passes from the recess 8 to a passage 9 and thence past the non-return valve to a passage 20. The valve member 2 is normally centralized by a spring 33. If the valve member is moved to the left radial passages 30 are brought into communication with a port 32 leading to the lefthand side of a double-acting jack 21 whilst radial passages 31 are moved beyond the end of the bore in which the member 2 reciprocates so that the left-hand side of the jack is connected through the bore 30, an axial bore 25, and the bores 31 with an exhaust passage 17. At the same time other radial passages in the movable member 2 will be brought into register with the passage 20 and radial bores 28 will coincide with a port 29 so that pressure liquid will be supplied through a bore 24 &c. to the right-hand side of the jack, causing the latter to move to the left. Similarly, movement of the valve member 2 to the right will cause movement of the jack to the right. The arrangement is such that the release and check valve can be readily removed without disturbing the main valve member 2. Modifications are described, suitable for controlling single-acting jacks, in which the member 2 is formed with only a single, axial bore.
