Title: Improvements in and relating to servo brake mechanism
IPC: B60T13/24
Filed: 1929-08-09
Abstract: 341,496. Fluid-pressure brakes. SERVO-FREIN DEWANDRE, SOC. ANON., 68, Quai de Rome, Liege, Belgium. Aug. 9, 1929, No. 24372. Convention date, Dec. 6, 1928. [Class 103 (i).] A pneumatic servomotor for the operation of the brakes of motor vehicles comprises a valveactuating pedal lever 10 pivoted at 9 upon a main lever 19 which is connected by the rod 18 to the brakes. The power piston 2 is connected by the member 14 to the lever 10 at 12. The control valve device comprises two relatively slidable valves 4, 5 controlling the connection of the cylinder 1 with the vacuum source and the atmosphere respectively by the pipe 3e and ports 1a, 1b. The valves 4, 5 are connected respectively by the cable 13 and sheath 8 of a Bowden mechanism to the levers 10, 19. The valve 5 is normally unseated as shown to connect the cylinder 1 to atmosphere. When the pedal plate 16 of the lever 10 is depressed the valves 4, 5 are opened and closed respectively and the cylinder 1 thereby connected to the vacuum source. The piston 2 acting through the lever 10 on the lever 19 thus applies the brakes. If the plate 16 is held stationary the lever 10 continues to turn about the pivot 15 and the valve 4 closes thus permitting a graduated application of the brakes. The pull of the piston 2 reacts through the lever 10 on the foot of the operator and the pressure applied to the brakes is thus indicated to him. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is applicable to servo motors in general. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in nuclear reactor installations
IPC: G21C1/00
Filed: 1961-07-07
Abstract: 984,692. Reactors. BABCOCK & WILCOX Ltd. July 7, 1961 [July 8, 1960], No. 24763/61. Heading G4G. In a gas cooled nuclear reactor circulation of the gas is effected, without a pump, by thermally induced gas flow through vertical ducting connecting the reactor pressure vessel with a heat exchange chamber above it. As shown, the reactor core 1 is cooled by the vertical flow of gas through channels 101, up duct 7 to pressure vessel 5 containing steam generator 4. The gas when cooled at 5 moves down through the annular space 108 to the lower pressure vessel space 110. The gas may be nitrogen, helium, or carbon dioxide at high pressure, and the reactor core is graphite with graphite-cased uranium oxide or carbide fuel elements. The plant is mounted in the ground within the vertical shaft 3. The heat release rate of the core is adjusted by control of the throttling valve 8 in the gas circuit. An automatic safety device directs the steam generated at 4 to a receiver when radio-active contaminations is detected. The gas in container 5 may be caused to recirculate round or by-pass the generator 4. To assist in the rapid removal of heat from the tube 7 at shut-down, cooling ducts may be arranged concentrically about 7. In an alternative reactor construction, not shown, the fuel is in the form of a mass of graphite spheres encasing fissile and fertile material held in a container of moderating material. As fresh fuel is added the resistance to coolant gas flow increases. This is allowed for by admitting gas to the fuel mass at progressively higher levels.
