Title: Improvements in or relating to Vapor Generators.
IPC: F28D7/02
Filed: 1967-08-31
Abstract: 1,166,304. Cooling reactors. GULF GENERAL ATOMIC Inc. 31 Aug., 1967 [22 Sept., 1966], No. 39882/67. Heading G6C. In a gas cooled, steam generating nuclear reactor, the core, heat exchangers and pumps are mounted within a prestressed concrete pressure vessel. To prevent the sudden large discharge of water and steam into the vessel interior upon the rupture of an individual heat exchanger tube, each tube is separately connected to exterior steam and feedwater headers. A slow discharge of steam into the vessel occurs upon the fracture of a tube, so permitting detection and the application of safety measures. A steam reheating tube bank is placed in the gas coolant flow, upstream of the superheating banks, thus damping temperature fluctuations at the superheating banks. In an emergency, the reheater is connected to an auxiliary cooling system and overheating of the heat exchangers prevented. The superheating and evaporating sections of exchangers are formed of different materials and the welded junction between the two is protected from the reactor coolant gas by a deflecting baffle.

A device for winding a web or a plurality of webs into a roll comprises a fixed or detachable spindle 1, having longitudinal grooves or fluting, and a disc 4 carrying a pivot 2 supporting an arm carrying a spreader comprising a palm having a curved point 5 and an extension 7. With the web 11 in a first position shown, the arm 3 is moved, manually or by engagement of a pin 8 with an abutment 9 on slight counterclockwise rotation of the disc, into a second position wrapping the web around the spindle. The disc is then rotated clockwise, with the spindle also rotating, to a third position with the pin 8 against an abutment 10, whereupon friction between the web and the extension 7 swings the arm 3 out to its original position. The edge 6 of the part 5 may be sharp, in which case a completed roll is removed from or with the spindle and located so as to bring the continuation of the web to the position shown, whereupon, when the parts are brought into the second position a jerk will sever the old web. The spindle 1 is driven by a shaft, the disc 4 being brought into frictional engagement with the shaft by slight tilting of the disc through the pivot 2 and arm 3 when the latter is in the second or third position, due to a force exerted by the spindle on the arm. After restoration of the arm to the first position, a spring restores the disc to its free position. Alternatively, the force may act to push a coupling member on the pivot 2 against the shaft, thus coupling the disc or an arm replacing the disc to the shaft.
