Patent DE-3718743-C1 (DE)
Title: Thermostat
Inventor: KOCH DIETRICH
IPC: G05D23/13
Filed: 1987-06-04
Granted: 1988-11-24
Abstract: The invention relates to a thermostat with two bellows made of metal which lie one inside the other and between which a working fluid is enclosed, which reacts to changes in temperature with a change in volume. The displaceable end of the inner bellows is connected to an activation element. The free end of the outer bellows lies opposite a stop. The increase in volume of the working fluid as a result of the influence of heat first causes an axial change in length of the outer bellows, until a predetermined temperature is reached. At this temperature the further movement of the outer bellows is prevented by an adjustable stop. In the case of a further increase in temperature and consequent further increase in volume of the working fluid, this displaces the inner bellows axially and thus also the activation element. The particular advantage of this arrangement is that the axial constructional space requirement of the thermostat is small. However, the actuating movements of the activation element are large in comparison with the expansion of the thermostat. In this way the working fluid does not alter its physical state. The response behaviour is favourable, since the required amount of working fluid is small because of the method of construction of the thermostat. <IMAGE>

Title: Method and apparatus for the continuous measurement and adjustment of the NH3 leakage in the waste stream from waste gas denitrogenation by means of ammonia
IPC: G01N27/416
Filed: 1988-06-21
Granted: 1989-11-09
Abstract: A process for the continuous measurement and adjustment of the NH3 leakage in the NH3-containing and water vapour-containing waste stream from waste gas denitrogenation by means of ammonia cools a diverted substream to a temperature below the dew point, conducts the condensate thus obtained over a pH measuring electrode, utilises the signal of this to control the ammonia feed and limits the amount of ammonia supplied, in each case to values at which a pH of 3-8 is established in the condensate. An apparatus for measuring the NH3 leakage in the abovementioned process is indicated. <IMAGE>
Patent DE-3829363-C1 (DE)
IPC: B23H7/26
Filed: 1988-08-30
Granted: 1990-02-22
Abstract: The invention relates to a method for the electroerosive machining of metal work pieces and a device for carrying out this method. The erosion machine itself is used to produce the electrode by its erosion head (1) traversing with a clamped blank to an attachment (8) for the cutting operation using a cutting tool, preferably a rotating milling tool (10) and moving the blank relative to the cutting tool (10) for machining according to a predetermined programme. Since the machining attachment (8) is arranged below the erosion head (1) - with vertical or horizontal axis of rotation - the electrode, after completion, can be used for the electroerosive machining without reclamping. Alternatively, an additional clamping fixture like an erosion head can be provided, by means of which electrodes can be produced or reworked in interaction with the machining attachment while a work piece can be machined in an electroerosive manner by means of the erosion head.
