Abstract: 1,131,548. Cooling reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 26 July, 1967 [8 Aug., 1966; 27 Jan., 1967], Nos. 35472/66 and 4140/67. Heading G6C. In a pressurized water reactor, the coolant pressurizer 52 is located outside and above the reactor pressure vessel 51 and effects coolant circulation by convection during coolant pump failure. A heat exchanger 64 in the upper part of the pressurizer condenses water vapour and generates a convection circulation between the pressurizer and reactor vessel when pump failure occurs. During normal operation the system pressure is maintained by electric heaters 62 in the liquid phase within the pressurizer. Upon an electrical failure, the heaters are inoperative and the heat exchanger induced circulation is brought into operation. Reactor decay heat is thereby removed from the core.

Abstract: 1,101,707. Mechanical interrupters. NIPPON DENSO CO. Ltd. 16 Aug., 1966 [17 Aug., 1965], No. 36567/66. Heading HlN. [Also in Division F1] The range of vacuum over which a suctionoperated timing advance for a contact-breaker of an internal-combustion engine is operative is extended by coupling a pull rod 8 from the control diaphragm 9 to the pivoted contactcarrying plate 4 via an intermediate lever 11 which changes its effective point of engagement with the plate 4 as the vacuum changes. The lever 11 is pivoted on the housing 2 at 13 and engages a pin 14 on plate 4 until the vacuum has increased sufficiently for lever 11 to engage a pin 15 at a reduced radius on plate 4. This reduces the advantage of lever 11 and necessitates a discrete increase in vacuum before the plate 4 is further advanced, the lever 11 then acting on the plate by means of pin 15 and aperture 12 allowing the pin 14 to move free of lever 11. In a modification (Figs. 6 to 8, not shown), the lever 11 is pivoted on the pin 15 and engages the pin 13 to reduce its advantage.
