Abstract: 1449192 Refrigerating CRYOGENIC TECHNOLOGY Inc 16 Nov 1973 [21 Nov 1972] 53464/73 Heading F4H A refrigeration system having at least two low temperature zones 42, 43, comprises a stepped housing 10 formed of a large diameter section 11 and at least one smaller diameter section 12; a large diameter displacer 14 and a small diameter displacer 17, and driving means whereby the displacer 14 is reciprocated by a driving rod 20. The system is arranged so that the displacer 14 imparts a reciprocating motion to the displacer 17 in such a manner that the displacer 17 reciprocates with a stroke length which is less than that of displacer 17. In the embodiment shown, the displacers are linked by an annular flange 26 on the end of displacer 17 and an inwardly extending lip 27 about the entrance of a cavity 28 on the bottom of displacer 14. In another embodiment (Fig. 3, not shown) a third, intermediate displacer is provided. The displacer 14 has a regenerator 30, and the displacer 17 a regenerator 31. The basic fluid flow path within the refrigerator comprises a relatively warm chamber 15, one or more fluid conduits 32, the regenerator 30, the clearances around flange 26 and lip 27 connecting regenerator 30 with the first refrigeration chamber 16, regenerator 31 which is in direct fluid communication through cavity 28 with regenerator 30, one or more fluid conduits 33, and the second colder refrigeration chamber 18. High-pressure fluid is supplied by a high pressure fluid source, e.g. the discharge side of compressor 34, through line 35 and valve 36 and low-pressure fluid is exhausted into a lowpressure reservoir, e.g. the inlet side of compressor 34 through line 37 and valve 38. In other embodiments the linkage between the displacers may include a perforated disc (108, Fig. 4) at the base of the regenerator 30; a flow, path from the regenerator 30 through an annular space (113, Fig. 5) between the cavity 28 and the wall of the refrigerator; a post (118, Fig. 6) which is integral with the disc (108) and has a flanged end which engages inwardly extending lips of the displacer 17, the lips enclosing a cavity; or a spring (116, Fig. 7) located between and contacting the displacers 14, 17. In further embodiments (Figs. 16-19, not shown), the displacers 14, 17 have adjacent flat end surfaces, the smaller displacer being associated with spring means at its lower end. In operation, the larger displacer drives the smaller displacer downwardly, the smaller displacer returning under the action of the spring.

The apparatus comprises an elongate tube 30 of rigid porous material, means, e.g. a positive displacement pump, for pumping the material axially through the tube 30, means for injecting a high pressure gas inwardly through the walls of the tube 30 so as to produce, in use, substantial turbulence, disintegration of the material within the tube and accelerated flow of the material, means 52 defining a chamber communicating with the tube 30 for receiving gas and material discharged from the tube 30 and heating means for heating the gas and material within the chamber. As shown the tube 30 is surrounded by a jacket 18 into which air or gas is injected by a compressor. The means 52 defining the chamber comprises a tapered perforate member enclosed by a housing 48, the space between the chamber walls and the housing 48 being in communication with a forced air gas or oil fired burner assembly 60. Material from the chamber proceeds into an evaporator tube 70 and from thence into a cyclone separator (Fig. 1, not shown). In a second embodiment particularly for burning sewage sludge the material issuing from the porous tube passes into a chamber into which air is injected and afterwards into a refractory lined chamber 110 into which a flame from an igniter unit 120 extends.

An air-cushion vehicle comprises a cabin with rigid sides 11, a bow access door 12 which is pivoted about a horizontal axis 13 and may serve as a loading ramp, and a skirt assembly formed from a flexible looped sheet 14, whose outer attachment lines to the sides 11 and to the door 12 are at 17 and 16 respectively, carrying a plurality of dependent segments 15. Slits 26 in the sheet 14 allow the door to be opened without tearing the sheet (Fig. 3, not shown). That part of the sheet 14 attached to the door 12 is formed with an extension (Fig. 4) which is folded back on itself along line 21 and edge 22 is affixed to strip 23. The free corner of the resulting triangular flap 19 is attached at 20 to that part of the sheet 14 which is attached to the sides 11. When the door is closed the flaps 19 cover the slits 26, and when pressurized air is supplied to the skirt assembly air enters the flaps 19 urging the inner walls of the flaps against the sheet 14, effectively sealing the slits 26. Alternatively (Fig. 8) the flexible sheet 14 may be attached to a buoyancy compartment 30 at lines 31, 32, below the level of the door 12, and a plurality of V-shaped elements 38 (constructed as in Fig. 7, not shown) attached to the sheet 14 at line 44 and to the sides and door at lines 39 and 40. When the door is opened the elements 38 part and those attached to the door are compressed beneath it; when the door is closed they return to place, and when the skirt assembly is supplied with pressurized air they are inflated via holes 43 so that the sides of adjacent elements 38 are urged together.

Abstract: 1,214,600. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 20 Nov., 1969 [18 Dec., 1968], No. 56760/69. Heading G6C. A nuclear reactor control rod drive assembly comprises: (a) primary motor means for delivering a variable speed drive; (b) primary transmission means for delivering the output of the primary motor means; (c) secondary motor means for delivering a constant speed drive; and (d) secondary transmission means for receiving drive from the secondary motor means and from the primary transmission means, and delivering a differential output, whose direction of output and rate of rotation are a function of its relative inputs, adjustment of the speed of the primary motor means determining the direction and rate of the differential output. Referring to Fig. 1, a cold type brake 16 is engaged and physically grabs and prevents rotation of a shaft 28 extending from primary motor 14 should the power source fail. Mounted integrally on shaft 28 is a ring gear 32 in a gear system 22, which system also includes idler gears 38 and a pinion gear 34. Pinion gear 34 is mounted on the end of a shaft 36 which passes through secondary motor 18 and carries a prime drive wheel 60 which supports three planet gears 61a engaged with internal teeth 52a of a flywheel ring gear 52. Ring gear 52, which is of large mass, is mounted on a hollow shaft 54 driven by the motor 18. Planetary gear system 24 is completed by a sun gear 66 mounted on the end of a shaft 68 which extends to form a ball screw 26. A control rod is connected to the ball screw 26 by a ball nut 74. In operation both primary and secondary motors 14, 18 are running continuously and with the gear ratios properly selected for gear systems 22, 24, motor 14 operating at 30 r.p.m. and motor 18 operating at 360 r.p.m., ball screw 26 is stationary. When it is desired to raise the control rod, motor 14 is increased in speed to 30À252 r.p.m. and sun gear 66 rotates 0À05 rev. for ech rev. of prime drive wheel 60. To lower the control rod, motor 14 is reduced in speed to 29À752 r.p.m. Motor 14 is a synchronous motor and the three speeds of 29À752, 30 and 30À252 r.p.m. are true synchronous speeds based on varying the number of poles in the stator, acting upon the rotor, with a 60 c/s. line frequency. Should cold brake 16 be actuated due to power failure, shaft 36 and prime drive wheel 60 are locked against rotation and there is a 5 : 1 speed increase for a rapid shut-down or scram. In the event of a power failure causing both actuation of cold brake 16 and failure of motor 18, the energy stored in flywheel ring gear 52 is sufficient to effect rapid shut-down.
