Patent DE-3712377-A1 (DE)
Title: Method of determining the wetting agent concentration in liquids and apparatus for carrying out the method
Inventor: MANER ASIM DR
IPC: G01N13/00
Filed: 1987-04-11
Abstract: The invention relates to a method for determining the wetting agent concentration in liquids and an apparatus for carrying out the method. In the automation of wet chemical processes, regulation of concentration requires the use of production measurement devices which can measure the concentration of the individual components of the process medium as simply as possible, preferably without sample preparation and on-line. The invention is to solve the technical problem of the determination of the wetting agent concentration in process media in accordance with the abovementioned criteria. In the measurement of the wetting agent concentration, the invention makes use of the fact that media containing wetting agents foam on stirring. The amount of the foam formed on stirring or the time in which the covering of foam formed breaks down again, depends on the wetting agent concentration in the process medium. In the solution of the invention, the process medium is foamed by stirring and subsequently, as a measure of the wetting agent concentration, the time in which the covering of foam goes down is measured.

Patent DE-3808633-A1 (DE)
Title: Method for producing dissolved salts and acids by ion exchanger resins
Inventor: GONZALEZ MANUEL OLIVO
IPC: B01J49/00
Filed: 1988-03-15
Abstract: A method for producing dissolved salts and acids from other available products using ion exchanger resins is described. The method is carried out in two stages, with provision of the exchanger resin in columns. In the first stage, the resin is loaded with the cation, corresponding to the salt to be produced, by passing a solution of an appropriate salt through the resin. The charged resin is taken off from the column cyclically, the resin taken off being simultaneously replaced by regenerated resin which originates from the second stage of the method. Before transfer of the resin from the first stage to the second stage, the salt solution with which the resin is loaded is removed by draining and washing with water or by displacement with another solution. In the second method stage, the resin is regenerated by the same solution of a salt or an acid, the anion of which corresponds to the desired salt.

Title: Arrangement for infrared radiant heaters
Inventor: LEHMANN HUBERT
IPC: A61N5/06
Filed: 1988-03-25
Abstract: The conventional infrared radiant heaters are also used as infrared healing radiant heaters for maintaining human health and beauty. The known arrangements for one or more radiators in a wide variety of mountings, however, are only intended for use in the selective irradiation of a locally delimited area through the free air space, a great deal of heat energy being passed unused into the ambient air of the radiators. Full utilisation of the generated heat energy for infrared healing irradiation of the whole body over the same application time is achieved by the arrangement of one or more infrared radiant heaters in a sauna or container. In order to meet the safety requirements the radiators are fitted under earthed dripping water and overheating guard plates of aluminium in porcelain sockets with silicone feed lines. Furthermore, a special temperature controller for simultaneous temperature control in the sauna is arranged as a protection against overheating of the radiators themselves and a time-limiting switch which switches off the current bipolarly is arranged as an additional protection. These infrared radiant heaters are arranged in different radiator directions, including the known sauna cabins with sauna oven, according to the invention, as accessory device.

Title: Dispensing system
Inventor: GRUBER GUENTHER DIPL ING
IPC: B67D3/00
Filed: 1988-03-31
Abstract: Essential features of this dispensing system are the selection switches (W) which are available for each tap (4a-4g) and actuation of which in each case results in the freely preprogrammable engagement of the function keys (F1-F5), the instantaneous engagement of the function key (F1-F5) which is brought about by pressing a selection switch (W) being displayed in the display unit (5). Actuation of a function key (F1-F4) then causes dispensing of that quantity of drink which is specified in the display unit (5). As the same function keys (F1-F5) are used for all the taps (4a-4g), it is possible to use much fewer keys than dispensing systems to date while retaining the same number of drinks portions which can be tapped, and in addition it is possible for the display unit (5) to provide more flexible "labelling" of the portions to be dispensed.

Inventor: LUBER GUENTER
IPC: H01F19/00
Filed: 1988-08-26
Abstract: A regulated switched-mode power supply with high-voltage generator for a television receiver presents particular problems with respect to the suppression of interfering resonances of the high-voltage winding, to the stabilisation of the critical secondary voltages and to the efficiency. Due to the combination of features according to the invention, the interfering resonant oscillation is suppressed by means of an auxiliary winding, the critical secondary voltages are stabilised by special coupling ratios between the primary and secondary windings and the eddy-current losses are avoided by dividing the air gap into several individual air gaps. The switched-mode power supply according to the invention is particularly suitable for television sets in which the switched-mode power supply operates at a frequency independent of the line frequency and, in addition to the low-voltage operating voltages, also generates the high voltage. <IMAGE>
