Patent GB-1151205-A (GB)
Title: Improvements in or relating to Jet Pumps and Nuclear Reactor Pumping Systems
Inventor: HOWARD CHARLES LEWIS
IPC: F04F5/46
Filed: 1966-07-28
Abstract: 1,151,205. Injectors. GENERAL ELECTRIC CO. July 28, 1966 [July 30, 1965], No.34027/66. Heading F1E. [Also in Division G6] A jet pump comprises an elongate hollow body which has an inlet and an outlet and includes a mixing chamber 52 and a diffuser 54 connected in series, the mixing chamber opening at one end to the pump inlet and the diffuser opening at one end to the pump outlet, a forward-flow nozzle 18 adjacent the pump inlet and a reverse-flow nozzle 55 for directing a fluid jet through the hollow body toward the pump inlet. The inducing fluid normally flows through an inlet 57 of a fluid switch 56 and through outlet 58 to the forward flow nozzle 18. To reverse the pumping direction a stream of control liquid is injected through line 31 to divert the inducing fluid-flow into a second outlet 61 and thence to the reverse-flow nozzle 55. The flow through the nozzle 55 can be adjusted from 0 to 100% of the fluid-flow through the fluid switch 56. In a modification the pump is arranged so that the flow is normally to the reverse-flow nozzle and is diverted by the fluid switch to the forward flow nozzle. In a further modification a number of reverse-flow nozzles (70, Fig.4, not shown) are arranged about the periphery of the mixing chamber. In an application to a nuclear reactor (see Division G6) a number of jet pumps, some being controlled as in Fig. 2 or Fig. 4 and others being controlled as in Fig. 3 are combined with pumps having no fluid switches or reverse-flow nozzles. The combination of pumps with different control arrangements ensures that the reactor flow comes to a safe condition on failure of the control fluidflow.

Title: Polyurethane materials
Inventor: COATES HAROLD
IPC: C08K5/524
Filed: 1964-08-20
Abstract: A polyurethane is prepared by reacting an organic polyisocyanate with an organic polyhydroxy compound in the presence of a tris-(2,3 - dibromoalkyl) phosphite.  A bis - (2,3-dihaloalkyl) - 2,3 - dihaloalkylphosphonate may also be present.  The polyhydroxy compound may be a linear or branched polypropylene ether of M.W. 1000-4000.

The arrangement enables the projector to be used either in the upright position of Fig. 1, in which case the aperture 12 becomes the projection aperture, or in the horizontal position of Fig. 2, in which case the aperture 11 becomes the projection aperture. The controls are arranged on the narrow side 1b of the projector housing. When the projector is used in the Fig. 2 position the mirrors are disposed as in Fig. 3. Mirror 14 is inclined at approximately 45 degrees to the beam from lens 13, which is reflected from mirror 14 to mirror 15, again inclined at 45 degrees to the beam, and hence projected in the required direction. For use in the Fig. 1 position, mirror 14 is swung out of the path of the beam from lens 13, which then emerges directly from aperture 12. In this case the position of mirror 15 is immaterial, and may be conveniently pivoted downwards to close the aperture 11. The two mirrors can be actuated simultaneously by a linkage mechanism, Figs. 4-6 (not shown), operated by a knob 10 on the housing.
