Title: Improvements in nuclear reactors
IPC: G21C19/04
Filed: 1964-06-29
Abstract: 1,001,118. Reactors. ATOMIC ENERGY OF CANADA Ltd. June 29, 1964 [July 8, 1963], No. 26811/64. Heading G6C. A right circular cylindrical nuclear reactor core contains a plurality of fuel channels each at an angle to the core axis, and having their ends at equal radial distances from the axis, as shown in Figs. 1a, 1b. The channels are straight, and the arrangement results in a closer spacing of the channels adjacent the core centre than at the periphery. The channels may all be at the same angle α, or they may be arranged in two concentric zones of different angle. Thus the neutron flux is maintained more constant in both axial and radial directions, and may be further improved'by using dual fuel handling equipment to enable fuel assemblies which include fertile material to be loaded successively into channels on one face, to progress through the reactor and be finally removed at the opposite face. Thus as fuel is burnt, the assembly approaches a central position of reduced channel pitch where its reactivity is reduced and the rate of plutonium conversion increases; beyond the centre part, the channel pitch increases as does the fuel reactivity, thus making full use of the fuel formed by plutonium conversion at the reactor core. Fuel handling (Fig. 8).-The core 80 has its axis horizontal; access to it is through a hatch closed by member 86. Fuel assemblies are fed to the skewed fuel channels 81 by a fuelling machine 88, and removed by a similar machine 89.

Title: Thermo-pump heating systems
IPC: F25B30/02
Filed: 1947-10-07
Abstract: 652,162. Heat pumps. EVANS, J. H. Oct. 7, 1947, No. 26883. [Class 29] In a heat pump driven by an internal' combustion engine or a gas turbine 25, the heat of the engine or turbine cooling water and the exhaust gases is utilized to supplement the heat from a low temperature source derived from the condenser 9 of the refrigerating system which includes a flooded evaporator 19 in which the liquid refrigerant circulates through tubes by thermosyphonic action and the level is controlled by a float valve 17. The exhaust gases are led by a pipe 28 to a heat-exchanger 29 through which passes water or other medium used to increase the temperature of the water or other medium heated by the condenser and circulated through the building &c. being heated. Compressed refrigerant vapour from the low pressure cylinder 1A of the two-stage compressor 1 passes by a pipe 3 to an inter-stage cooler 4 and thence by a pipe 7 to the high pressure cylinder 1B whence it passes by a pipe 8 to the condenser 9. Condensed refrigerant is collected in a receiver 11 capable of holding the full charge of refrigerant for the plant, and is fed through a heat-exchanger or pre-cooler 13 to a vessel 16 the feed being controlled by a float valve 17. From the vessel 16 liquid refrigerant flows through a pipe 18 to the flooded evaporator 19 of the shell and tube type. A mixture of refrigerant liquid and vapour leaves the evaporator through a pipe 22 and enters the vessel 16 through a pipe 23 branched so as to release vapour to the upper part and liquid to the lower part of the vessel, without breaking the liquid syphon, causing thermosyphonic circulation of refrigerant through the evaporator and the vessel 16. The vapour is returned to the compressor 1 through pipe 24, pre-cooler 13 and pipe 2. The water, air or other medium supplying the low temperature heat is circulated through the evaporator by pipes 20, 21. Cooled water returning from the hot-water heating system of the building &c. through pipes 35 is circulated by a pump 37 through pipes 39, 5, 26, 30 to the water jacket of the compressor, condenser 9, water jacket of engine 25 and exhaust gas heat-exchanger 29 respectively, the heated water returning through pipes 41, 6, 27, 31 to a distributing header 40. Valves are provided in the various water pipes for regulating the temperature. The heated water may be used in a heat-exchanger 43 to heat ventilating air for the building, drawn in by a fan 47 through a filter 46 and supplied to the building by a duct 48, part of the used air being re-circulated at 51. A thermostat in the duct 48 or in the hot-water pipe 40 regulates the speed of the engine or gas turbine 25. Specifications 652,214, 652,215, 652,216, 652,217, 652,218 and U.S.A.

Abstract: 535,075. Toothed gearing: fluid-pressure servomotors. MAXSON CORPORATION, W. L. Oct. 4, 1939, No. 27185. Convention date, July 15. [Class 80 (i)] [Also in Group XXIX] A high torque shaft 44 is driven in unison with a low power control shaft 70 by driving the shaft 44 by means of gears 41, 42, Fig. 7, operated by differential gears from shafts 13, 14 driven by gearing from a high power motor M, indicated diagrammatically in Fig 1. The shaft 44 is connected by gears 84, 82, 83, with the shaft 70, so that the shafts 44, 70 normally synchronize, and any lack of synchronization of the shaft brings into operation mechanism which restores synchronization. This mechanism comprises braking means in the form of gear pumps 47, 48 : 49, 50 driven from the shafts 31, 32 of the gears 41, 42. The shafts 31, 32 are attached to the planet gear carriers of planet wheels co-operating with sun wheels 35, 36, and input gears 17, 18 of the differential gearing driven by the motor M. The gear pumps direct streams of oil to opposite sides of a cylinder 87 in which is a piston 88, and a valve 58 controls the outflow of oil so that normally the outflow of oil from the pumps maintains the piston 88 in mid position and a brake comprising adjustable shoes 108 on levers 105 is applied by a spring 106 to brake the shaft 44. The valve 58 is carried by a lever fitted with a pin 79 engaged by a slot in an arm 77 free on the shaft 70. This arm is moved out of its normal position when the gears 83, 84 are not rotating equally, and so the valve is then operated to restore equality of movement, and the brake 108 provided is for the purpose of preventing " hunting " movement.
