Title: Improvements in or relating to air pressure braking systems
Inventor: FARMERY GEORGE KENNETH
IPC: B60T8/36
Filed: 1964-03-05
Abstract: 1,032,578. Fluid pressure brakes. CLAYTON DEWANDRE CO. Ltd. March 5, 1965 [March 5, 1964], No. 9358/64. Heading F2F. In a compressed air vehicle braking system comprising an automatically-operating antiskid device (not shown) which, on sensing wheellocking, energizes a solenoid 16 to operate a valve element 8, initial displacement of the said element interrupts supply of compressed air to a two-chamber brake cylinder whilst further movement of said element interconnects opposite sides of the diaphragm 4 or piston of the cylinder to destroy the pressure differential across the diaphragm or piston to effect brake release. During normal brake operation, the spool-like valve element 8 is urged by spring 21 to the top of its housing 7 which is bolted to a double-chamber brake cylinder formed by a diaphragm 4 clamped between dished plates 1 and 2 by a ring 3. Compressed air is fed from a source (not shown) by a driver's valve (not shown) through an inlet port 9, past the waisted portion 8b of the spool, through outlet port 10 to the chamber on the left-hand side of the diaphragm. In addition, the chamber on the righthand side of the diaphragm is vented to atmosphere through line 12, port 11 and exhaust 13. Consequently, thrust rod 6 is moved to the right to apply the brake. On wheel-lock being sensed, the anti-skid device energizes solenoid 16 which actuates a pilot valve 17. This valve connects a port 20, normally vented through opening 18, to a further compressed air inlet 19. The valve element 8 is displaced downwards to the position shown to initially cut-off the connections between ports 9 and 10 and ports 11 and 13, respectively. Further downwards movement of the valve element then interconnects ports 10 and 11 to equalize the pressure across the diaphragm and destroy the braking force. The arrangement is said to conserve the compressed air supply and ensure rapid re-application of the brake, if necessary, by the residual pressure remaining in the chamber on the left-hand side of the diaphragm.

Title: Method and apparatus for heating a combustion supporting gas for an mhd device
IPC: H02K44/08
Filed: 1967-03-01
Abstract: 1,127,712. MHD power plant. AVCO CORP. 1 March, 1967 [2 May, 1966], No. 9788/67. Heading H2A. In an MHD power plant using a high temperature plasma comprising combustion gases seeded with an alkali, the seeded plasma exhausted from the MHD generator is passed through a storage-type regenerative heater in alternation with air or other combustion-supporting gas, substantially all the heat transfer medium in the heater in contact with the seeded plasma being heated by the seeded plasma to a temperature greater than the temperature at which the equilibrium vapour pressure of the seed material equals its partial pressure. At the beginning of each heat storage cycle, condensation and deposition of seed material within the heater occurs until the temperature of the coolest part of the heat transfer medium (pebbles or refractory bricks) is above the dew point of the seed material, the deposited seed material is re-evaporated and carried away by the plasma. Blockage of the heater by accumulated seed material is thus prevented, and the seed material is retained in the plasma for subsequent recovery and re-use. Three heaters may be used, the arrangement being such that one heater heats the air while the two other heaters are being heated by the plasma. The valves for controlling the flow of air and plasma through the heaters may be opened and closed automatically by timing means or by temperature sensors located at each end of each heater.

Abstract: 1,178,041. Heat hardened pellets. ARTHUR G. McKEE & CO. 2 March, 1967 [11 March, 1966], No. 9889/67. Heading C1A. Hard pellets of a finely divided material are produced by forming green balls of the material, conveying the balls on a travelling grate through a heat hardening zone, and discharging the pellets directly into a tumbling zone, e.g. an inclined rotary kiln, maintained at the hardening temperature. The balls may be initially passed through updraught and downdraught drying zones at 400-850‹ F. and 800-2100‹ F. resp. In the hardening zone, the balls may be heated at 2350-2600‹ F. using combustion gases, preferably oxidizing, in downdraught, and the exhaust gases may be used in the drying zones. The rotary kiln may be heated by a burner at the feed end, and oxidizing or reducing conditions may be maintained by control of fuel, or by adding coal, coke, peat, carbonaceous wastes, or fuel oils. Sintering may occur in the hardening or tumbling zones. The hardened pellets may be cooled on vibrating conveyers by air, which may then serve as combustion air in the hardening zone, or as drying air. Tempering air may be added at any stage. The balls may be made from Fe ore or concentrates or flue dust, and may contain fuel or flux, e.g. lime, limestone, dolomite, or sand. The travelling grate has a plurality of moving pallets each with permeable bottoms. The upper track has an inclined portion, which causes the pallets to tip their loads into a shoot which is inclined laterally from the track and feeds directly to the kiln. Each pallet is individually pulled up the inclined portion by levered arms which hook on to the axles of the pallet wheels.
