Patent FI-935275-A (FI)
Inventor: PEDERSEN IB OBEL
IPC: A23L3/01
Filed: 1993-11-26
Abstract: A method of heating media flowing through an insulating pipe by means of high-frequency electrical power. The medium is fed through a pipe of a substantially electrically non-conducting material and only presenting minor dielectric losses, and around which two ring electrodes are arranged at such a mutual axial distance that the two electrode rings are mutually spaced by a predetermined pipe length connecting said electrodes to the terminals of an HF generator and applying an HF voltage from the HF generator. In this manner a uniform and efficient heating is obtained of the flowing medium or fluid (granulate, liquid or gas) without said medium necessarily getting into direct contact with a heating means and without said medium escaping from its conveying pipe. The latter is very advantageous in connection with many uses, such as when toxic or aggressive media apply, and also when sensitive media are involved which do not endure getting in contact with the atmosphere.

Abstract: The invention relates to a concrete plate, consisting of a concrete material, and a process for producing it. The plate is produced by casting a concrete mix in a mould and pressing the concrete mix in the mould. According to the invention, at least two concrete layers, consisting of different mixes, are cast on top of each other in this connection. The water/cement ratio in the mix which forms the supporting layer of the plate is low as compared with the water/cement ratio in the mix which forms the outer layer. The outer layer-forming mix employed is a concrete mix which contains, calculated on the quantity of binder cement, approx. 1-20%, preferably approx. 5-15%, of finely divided, calcined kaolin. The layers which are cast on top of each other are pressed with the same compression in order to form a 2-layer press plate. The invention achieves a concrete plate which can be used for the facades of buildings and for interior fittings and similar representational uses. Whereas the plates are in the same class as many natural stone plates with regard to their density, they are considerably easier to colour than are these natural stone plates.

Abstract: 137,597. Baumann, K., and British Westinghouse Electric & Manufacturing Co. Jan. 16, 1919. Feed-water, heating. - In a steampower plant comprising a main turbine and one or more auxiliary turbines, the boiler feed-water, which is usually the condensate from the main condenser, is passed in series through separate heaters supplied respectively with steam at different pressures taken from two or more stages of the auxiliary turbine or from two or more auxiliary turbines. Separate heaters may be replaced by a single heater divided into a number of separate compartments. The condensate from the main condenser 7, Fig. 1, is passed by a pump 8 through heaters 10, 11 heated by steam from stages 12, 13 of the auxiliary turbine 9. A relief valve 19 on the auxiliary turbine allows uncondensed steam to escape to the atmosphere, or to pass up to the main or auxiliary condenser, or to a stage of the main turbine, or to a heater in connexion with the main turbine. The pipe 18 conducting the condensate from the heaters to the main condenser is fitted with a valve 21 adapted to close when the vacuum in the conclens'er falls below a predetermined limit. A. valve 20 in the pipe 18 allows non-condensable gases from the heaters to escape when the valve 21 is closed. Before passing through the heaters 10, 11, the feed-water may pass through a heater supplied with steam from a low-pressure stage of the main turbine. An auxiliary condenser 23. Fig. 3, may be connected to a heater 10 supplied with steam from the last stage of the auxiliary turbine. A back-pressure valve 24 is adapted to open and allow steam to pass to the auxiliary condenser when the pressure in the heater rises above a certain point. Adjustable valves or diaphragms 25 for decreasing the size of the passages are fitted in the pipes connecting the heaters to the main condenser. Heaters supplied with steam from separate auxiliary turbines are connected together by a steam-pipe fitted with a valve arranged to open, when the pressure in one of the heaters exceeds a certain limit, so as to allow the surplus steam to pass to the other heater. A closed or open storage tank 47, Fig. 8, may be inserted between the heaters. The exhaust 35 of the auxiliary turbine is, in this apparatus, connected to the. main turbine by a pipe 36 fitted with a valve 58 so controlled by the pressure in a heater 11 that the valve is opened when the air pressure rises above a predetermined limit.
