Abstract: 1,199,357. Nuclear power plant. NUCLEAR POWER GROUP Ltd. 18 Sept., 1969 [27 Sept., 1968], No. 46069/68. Heading G6C. In a nuclear power plant, a gas turbine, heat exchangers and a reactor are mounted in separate cavities in a prestressed concrete pressure vessel. Carbon dioxide or helium, heated in the reactor cavity 14, passes through the ducts 21 to the compressor turbine 4 in the cavity 10 and main turbine 5. From 5, the gas is cooled in heat exchanger 7 and the precooler 8, both in cavity 13. The gas leaves 13 and passes through the compressors 2, 3, in cavity 10, after which it is heated in exchanger 7, in 13 and returned to the reactor in cavity 14. The main turbine 5 and the electrical generator 6 are mounted in the cavity 15. The casings of turbines 4 and 5 are coupled together.

Filed: 1972-10-06
Abstract: 1384933 Track junction without movable parts, elevated railways FRIED KRUPP GmbH 6 Oct 1972 [9 Oct 1971] 46275/72 Headings B7L and B7N In an arrangement for routing a vehicle to one or other branch of a track junction which has no moving parts, magnetic apparatus is provided on the vehicle which co-operates with a guide part of the track at the junction formed of soft magnetic material. As described vehicle 5 is supported by a magnetic support system 6 on a part 4 of an overhead track and is normally guided by means (not shown) co-operating with upstanding parts 2, 3 of the track. On the vehicle a cross member is provided at one end with a permanent magnet 7 and at its other end with electromagnet 8. For routing the vehicle to right hand branch 17 the electromagnet is de-energized and the permanent magnet co-operates with the part 2 which is of soft magnet material at the junction. For routing the vehicle to the left the electromagnet is energized and co-operates with part 3 which is also of magnetic material at the junction. The electromagnet is of sufficient strength to guide the vehicle, against the pull of the permanent magnet, to follow the left hand branch 18. In the event of failure of control energy to the electromagnet the vehicle is always routed to the righthand branch. Figs. 2 and 3 (not shown), illustrate arrangements using permanent magnets mounted on a cross member which is movable transversely of the vehicle by solenoid or magnetic action to route the vehicle to the left hand branch and returned by spring or magnetic action to a position for routing the vehicle to the right. In the event of control energy failure the cross member stays in this latter position and routes the vehicle to the right hand path.
