Title: Method and means for utilizing steam generated by solar heat
IPC: F24S10/70
Filed: 1928-01-23
Abstract: 299,294. Spiess, E. Oct. 22, 1927, [Convention date]. Working - fluid supply; motor power plant. - A plant for converting solar heat into electric energy comprises sets of boiler tubes 5 arranged upon a heat-insulating floor 4 under a glass roof 2. A masonry wall 3 is arranged on the north side. A machine room 13 is provided underground, and is protected by outer heat-insulating walls 15, and ventilated by ducts 17, 18. Steam generated in the boiler 5 passes through superheating tubes 10 to a turbine 20. The exhaust from this turbine is divided into two or more second stage turbines 21, and the second portion to the header 41 of the inner tubes 32 of one or more regenerators 31. The exhaust from the turbines 21 is passed to condensers 22 and water separators 26 from which the steam is passed by fans 30 to the outer parts of the regenerators 31. The two portions of steam from the regenerators 31 are mixed in a tank 37, compressed by a pump 40, and passed to the second-stage turbine 21. The condensate from the separators 26 is delivered by a pump 29 partly to the boiler tubes 5, and partly to a refrigerator 45 which supplies the cooling water for the condensers 22. The turbines drive electric generators, and automatic control-gear is provided. The auxiliary machinery is driven from a storage battery which is charged by a separate generator on starting the plant. Specification 300,995, [Class 64 (ii), Heating systems &c.], is referred to.

Title: Improved method of controlling the temperature of superheated steam and apparatus therefor
IPC: F22G5/20
Filed: 1931-01-22
Abstract: 368,007. Steam superheaters. YARROW, H. E., of Yarrow & Co., Ltd., Scotstoun, Glasgow. Jan. 22, 1931, No. 2167. Addition to 353,271. [Class 123 (iii).] The temperature of superheated steam is controlled by withdrawing it from one section J<0> of the superheater, spraying it with water and returning it to a later section H<0>. Steam is withdrawn from the section J<0> through tubes O opening into a drum M divided by a transverse partition with a central aperture through which water is sprayed by a nozzle R. The desuperheated steam flows through tubes P to the last superheater section H<0>. The supply of spray water may be automatically controlled by a thermostat at the outlet of the superheater.

Title: Process for initiating and maintaining high tension currents in gas purifying apparatus
IPC: H02M7/06
Filed: 1931-01-22
Abstract: 371,859. Automatic regulation; rectifying. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Jan. 22, 1931, No. 2209. Convention date, Jan. 23, 1930. [Classes 38 (ii) and 38 (iv).] Supplying consuming devices.-Relates to an arrangement for automatically regulating high tension D.C. supplied to apparatus such as dust separators. Closure of a starting switch energizes the filament of a rectifier valve 4 and starts a motor 11 which through a friction clutch 12 rotates the contact arm of a rheostat 8 in the primary circuit of a transformer 3 the secondary of which supplies the dust separator through the rectifier 4. The voltage applied to the separator increases rapidly up to a certain value and then slowly above that value until arcing occurs. When a substantial amount of resistance has been removed a contact ring 45 on ratchet wheel 13 connects a transformer 28 to the mains so as to charge condensers 25, 26 through a rectifier 27. When arcing occurs in the separator the grid voltage of a valve 18 connected to the electrode 2 by a coherer &c. rises, the valve becomes conductive and the condensers 25, 26 discharge through a coil 31. This temporarily closes a switch which completes the circuit through a coil 34 to close switches 35, 36. Switch 35 completes a maintaining circuit for the coil 34 and switch 35 energizes a coil 17 which actuates a plunger 15 to move rheostat back and reduce the voltage to below sparking limit, and also disconnects the transformer 28. The cycle then commences again.

As shown, the end of the tube 3 is turned over the ferrule 6 of metal or other rigid material, and the ring 9 has a conical bore formed with annular ribs 14. In modifications, (a) the end of the hose 1 is belled outwardly by the application of heat, (b) the ring 9, Fig. 4, is screwed into a thrust cap 18 and the spring 15 acts between the end wall 23 of the cap and a washer 19, and (c) the ring 9 is integral with or secured to a sleeve 29 telescopically arranged about a sleeve 30, there being a bayonet joint between the sleeves so that the latter may temporarily lock the spring 15 under compression and to expose the turned over end 5 of the inner component.

Abstract: 699,945. Clothes drying apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 4, 1952 [Feb. 3, 1951], No. 2916/52. Class 34 (ii) A tumbler drier with a foraminated drum 40 within a heater chamber formed by horseshoe shaped panels 16, 17 and a wrapped sheet 19 has a heater 26, an exhaust duct communicating between the heater chamber and the outer atmosphere, and a plenum chamber into which atmospheric air is passed by a fan 72 to raise the pressure therein above atmospheric, the plenum chamber discharging the air into the heater chamber in two streams, one of which flows about thd rum and heater the other flowing towards the exhaust duct to dilute the heated exhaust air and reduce its temperature before it is discharged. The plenum chamber comprises the base 2 of the apparatus, the sheet 19 and a side wall plate 70 and roof plate 71. Fan 72 draws air through louvres 38 into the plenum chamber from which it discharges under pressure through narrow slots 74, 75 parallel to the tumbler axis. Discharge of the air from the heater chamber is via a lint trap of drawer-like structure having a base from which sides 77 extend upwardly and a sloping mouth structure 78 and screen 82. A port 88 in the walls 77 allows discharge of air if the screen becomes blocked by lint. In a modification (Fig. 10) a drawer-like structure 90 has a front panel 91 covering the opening in the toe-board and sealed by a gasket 92, side walls 95 and a sloping screen 96 occupying substantially the full width and length of the drawer. A thermostat 107 having a bulb 108 controls the air temperature in the heater chamber and a limit switch protects against overheating due to thermostat failure. An ozone producing lamp 121 is located within the plenum chamber and a timer switch provides a cooling period in which the heater is switched off while the motor driving the drum is still running. A centrifugal switch also cuts out the heater if the motor operates below normal running speed.
