Abstract: 1416053 Gas filter bed BELGONUCLEAIRE SA and CENTRE D'ETUDE DE L'ENERGIE NUCLEAIRE 3 Sept 1973 [6 Sept 1972] 41347/73 Heading BIT [Also in Division F4] Waste gases from an incinerator are passed to a particle bed type filter, and the particles of the filter are automatically regenerated in a fluidised bed. Waste material is fed to a furnace 1 and the gases are passed to a fluidised bed 10 for secondary combustion. From an expansion chamber 12 above the fluidised bed the gases pass through a panel bed filter 30 to the stack 45. An offtake 17 immersed in the bed leads to separator 20 whence gas is returned to the fluidised bed, and particles regenerated in the fluidised bed are fed to a storage hopper 35 feeding the filter 30. When the differential pressure across the filter increases above a set limit, compressed air apparatus 36 pushes filter bed particles between the louvres 31 to fall into the fluidised bed for regeneration. They are replaced by particles from the storage hopper 35. The combustion gases from the incinerator furnace may pass directly to the expansion chamber 12.

Filed: 1960-12-02
Abstract: 922,849. Pneumatic suspension control valves. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 8, 1961 [Dec. 2, 1960], No. 41481/60. Class 108(2) A control unit for an air suspension levelling valve comprises a body 10 containing a valve 21 carried by a diaphragm 20 and a spring loaded disc valve 16 which permits pressurized fluid to flow to the diaphragm 20 during rapid vertical movement of the vehicle whereupon the valve 21 prevents air flow between an air reservoir (not shown) and the air springs (not shown) of the vehicle. As shown, a control unit is screwed into each end of the cylinder 12 of a doubleacting hydraulic shock absorber 13. One control unit has a connection 25 from the air reservoir and a connection 26 leading to a levelling valve (not shown) and the other control unit has a connection 27 from the levelling valve and a connection 28 to the air springs. Increased hydraulic pressure at either end of the cylinder 12 due to spring deflections lifts one of the disc valves 16 and acts on the diaphragm 20 to close the valve 21. Upon release of the increased hydraulic pressure by the shock absorber piston the disc valve 16 closes and a bleed hole 19 therein permits the pressure acting on the diaphragm to escape slowly. Consequently the reservoir will only communicate with the air springs during prolonged spring deflections since at all times during oscillating motion of the shock absorber one of the valves 21 will be closed. The control units may be associated with a vane type shock absorber.

Abstract: 1,128,910. Shift registers. INTERNATIONAL BUSINESS MACHINES CORP. 19 Sept., 1966 [22 Oct., 1965], No. 41651/66. Heading G4C. [Also in Division H3] A shift register includes a plurality of identical stages in series, each stage comprising a first and a second identical sub-circuit each containing an AND input circuit and a bi-stable semi-conductor device, mutually out-of-phase pulses being applied to alternate sub-circuits for advancing data in turn from sub-circuit to sub-circuit and from stage to stage. As shown, each stage 2-1, 2-2, 2-3 comprises a pair of silicon-controlled rectifiers such as 50 and 51 each having a control electrode connected to a diode AND-gate such as 55 or 65. One input of each AND-gate is connected to a source of pulses 5 and the other input receives data either from the input 61 (in the case of the first subcircuit of the first stage) or from the anode of the previous rectifier. The transistorized pulse generating means 5 coupled to a clock 4 produces alternate advance pulses on the lines 30, 31 so that during the first half-cycle data is transferred into the respective first sub-circuits and during the second half-cycle into the respective second sub-circuits. AND-circuits 7 and 8 connected to clock 4 provide reset pulses on lines 40, 41 alternately so as to disconnect the cathodes of the rectifiers from the source of operating potential prior to the entry of new data into the respective rectifiers. The rectifiers are preferably monolithically fabricated on a semi-conductor chip. A two-transistor equivalent of the silicon-controlled rectifier may be used instead, as may pulse-controlled rectifiers. Other semi-conductor materials than silicon may be employed.
