Title: Water blending valve - using spring loaded disc valve as by=pass to water softening plant
Inventor: BUSCH AUGUST
IPC: C02F5/00
Filed: 1980-02-01
Abstract: A device for blending softened water with hard raw water has one inlet for the raw water, two connections for the inlet to and the outlet from the water softening plant, and one outlet for the blended water. A spring loaded disc valve between the two stop valves for the water softening circuit is designed as a disc valve which opens in the direction of flow. The valve disc surface towards its valve seal is directly exposed to the raw water pressure, and the opposite disc surface to the blended water pressure. This keeps the hardness of the blended water constant, independent of fluctuations of the water pressure or of the water draw-off rate. The new valve is simple and can be produced at low cost.

Patent DE-3040510-A1 (DE)
Inventor: BRASS HOLGER ING GRAD
IPC: F24J2/00
Filed: 1980-10-28
Abstract: In ambient-air heat absorbers composed of many heat exchanger elements arranged one above another, the flowing air often flows too smoothly through the intermediate spaces, so that the heat exchange takes place only incompletely. As a result of the insertion of lattice grids onto the (smooth) surface of the heat exchanger elements, this uniform flow is varied. The result of this is a greater absorption of heat by the absorber.

Title: Method and apparatus for monitoring the superheat level of steam
Inventor: DAY BOBBY L
IPC: G01N25/60
Filed: 1981-03-07
Abstract: In plants running with superheated steam, a fall in the prescribed temperature can cause considerable damage to components of the plant. For monitoring the superheat level, the saturation pressure of water, corresponding to the steam temperature, is determined via indirect contact with the steam. This saturation pressure is compared with the steam pressure. The ratio of these pressure values serves as an indication of the superheat level of the steam. This ratio is determined by means of a differential-pressure measurement transducer (4), one measuring chamber (10) of which is connected via the line (9) directly to the steam (2). A line (5), which is filled with water up to the line (6) and has a closed end (8), is connected to another measuring chamber (4). The water-filling leaves a free space (7) in the line (5). A part of the water-filled zone of this line (5) protrudes into the pipe (1), so that the water in this zone assumes the temperature of the steam flowing in the pipe. <IMAGE>
