Patent GB-763919-A (GB)
Title: Steam power plants
IPC: F22G5/00
Filed: 1955-01-25
Abstract: 763,919. Steam turbine plant. SULZER FRERES SOC. ANON. Jan. 25, 1955 [Feb. 10, 1954], No. 2249/55. Class 110 (3). [Also in Group XIII] A steam power plant comprises a forced-flow, once-through steam generator which may operate at supercritical pressure and which has a furnace 3 lined with steam-generating tubes 8 and locating in its top portion a radiant superheater 11, 12, combustion gases passing laterally from the furnace through a short pass in which is disposed a reheater 16 and then downwardly through a pass locating a primary superheater 10 and feedwater preheater 6, the latter including a heat exchanger section 27, 28 wherein the incoming feed is further heated by steam tapped off from one of the turbines supplied by the generator. The heated feed is converted into steam in the tubes 8 and passes through a conduit 9, the primary superheater 10 and the radiant superheater 11, 12 to the highpressure turbine 14. Steam from this turbine returns to the generator through a pipe 15 and passes through the reheater 16 and then through a heat exchanger constituted by tubes 21 disposed coaxially within some of the radiant superheater tubes, so that the steam is further reheated in indirect contact with the superheated steam. The reheated steam flows to the low-pressure turbine 18 through a pipe 17. The tubes 21 are protected against overheating when the generator is being started up by the superheated steam flow. Fig. 2 shows a reheater disposed wholly within the convection pass from the furnace 3 and means whereby the temperature of reheat is regulated. The superheated steam from the primary superheater 31 flows through a heat exchanger consisting of a tube 33 disposed within a tube 38 through which passes steam from a reheater 37, the reheated steam flowing from tube 38 through a further reheater section 39 before returning to the lowpressure turbine through pipe 17. Superheated steam from tube 33 passes through a final superheater 36 and a pipe 13 to the high-pressure turbine. The reheat temperature is controlled indirectly by varying the temperature of the superheated steam entering the heat exchanger 33, 38 by means of a water spray attemperator 40 in the inlet pipe. The superheat temperature is subsequently adjusted to the required level by attemperation by means of a spray 41 in the heat exchanger outlet pipe 35 or by raising its temperature by opening a valve 43 to allow some of the steam to by-pass the heat exchanger. Specification 731,338, [Group XIII], is referred to.

[Also in Division G1] A guiding device for a tool e.g. a small powesaw or for a marking instrument comprises a straight edge 1 connected to a plate 2 by parallel rods 3 so that the edge 1 can be moved parallel to the plate, a stock 7 secured to the plate 2 by bolts and wing nuts 8, 9 allowing the angle between the plate 2 and stock 7 to be adjusted, and an anchor bar 11 secured to the stock the anchor bar having a clamp 12 enabling the device to be clamped to a workpiece 13. The parallel movement between the straight edge 1 and plate 2 may be effected by rotation of a knob 4 with a cog wheel 5 meshing with a further cog 6 at one end of one of the rods 3. Alternatively a cam device or an eccentrically mounted wheel may be used. Locking devices are also provided to hold the straight edge 1 in its adjusted position. Mating guide means, e.g. a groove or flange, may be provided on the straight edge and the saw to facilitate its use. By means of the nuts 8, 9 the straight edge 1 may be set at any desired angle on the workpiece 13 and by moving the edge 1 parallel to the plate 2 in incremental steps between each movement of the saw along the edge, a desired groove may be cut in the workpiece 13.

Abstract: 1,136,175. Liquid coolers. K. A. OESTERHELD. 20 Jan., 1967 [25 Jan., 1966], No. 3032/67. Heading F4S. A heat exchanger in which a natural or forced draught of air is used for cooling liquids comprises a plurality of horizontal tubes 1 of square cross-section arranged in vertically spaced superposed rows. Supporting members 3 recessed to position the tubes are attached to a frame consisting of four vertical posts 2. Air passes through the tubes into a draught duct 13. The natural draught obtained within the duct can be controlled by a flap 14. The liquid to be cooled, stored in a tank 6, is passed over the tubes 1 and is collected in a basin 5. Pipe conduits 7 supply channels 8 with liquid from the tank. The channels 8 are provided with sloping surfaces (9, see Fig. 2) to evenly distribute a continuous film of liquid over the tube surfaces. The tubes 1 are preferably made of hygroscopic material, e.g. asbestos or fibrous cement, and resulting filtering of liquid through the tube walls leads to evaporation within the tubes hence augmenting the cooling efficiency of the arrangement. Other tubular crosssections, e.g. rectangular or circular, may be employed.
