Patent DE-3532661-A1 (DE)
Title: Signal matching circuit
Inventor: KALUZNY MICHEL
IPC: G01R19/165
Filed: 1985-09-13
Abstract: The invention relates to a signal matching circuit for converting one or more voltage signals, applied in each case to an input from a predefined, limited voltage range whose upper limit lies above the lower limit by an essentially fixed factor, into a voltage signal with a predetermined fixed value at the output of at least one channel of the circuit which in each case comprises an essentially symmetrical input (1, 2) in each case with a series resistor (3) in the input lines (1', 2'), a rectifier (4), an optocoupler (5), a noise-pulse suppression circuit (6) and devices (7) for generating a stable output voltage. In order to increase substantially the voltage range to be detected unambiguously from the same channel and to be able to convert both AC and DC voltages of any polarity with the aid of the circuit in a suitable manner, it is proposed according to the invention that the noise-pulse suppression circuit (6) is connected downstream of the optocoupler (5) in at least one channel, that the factor between the upper and lower limits of the detectable input voltage range is at least 10, and that the optocoupler (5) has a current amplification factor of at least 200. <IMAGE>

Title: Control circuit for a heating system
Inventor: ALBRECHT ROBERT
IPC: F24D19/10
Filed: 1985-10-19
Abstract: A heating system control circuit dependent on room temperature and outside temperature is intended to generate an output control signal. Although this signal does not contain the operating temperature, the setting of the room temperature controller 17 is corrected in it in such a way that given a specific setting of the room temperature controller 17 the room temperature change corresponding to the specific setting is produced despite differing heat curves and differing outside temperatures. An input circuit 1 dependent on the operating temperature is provided for this purpose. This circuit comprises the outside temperature sensor 6, the room temperature sensor 16, the heating curve controller 10 and the room temperature controller 17, as well as an interface circuit 19. The latter is controlled by the heating curve controller 10 in such a way that adjusting the room temperature by a specific amount leads to a stronger change in output voltage U1. <IMAGE>

Title: Frequency filter
Inventor: WENDEL WOLFGANG
IPC: H03H7/46
Filed: 1985-10-29
Abstract: In a frequency filter preferably for dividing a full frequency range into two frequency sub-ranges, the first of which comprises a lower and an upper part of the full frequency range and the second of which lies at least partly between the upper and the lower part, a range attenuation component designed as a bridged T-network is provided according to the invention in which the two series-connected direct-axis resistors connecting the input and the output for the first frequency sub-range and corresponding to the characteristic impedance are bridged by a parallel resonant circuit tuned to the frequency mid-way between the upper and the lower part of the first frequency sub-range and in which a series resonant circuit which is tuned to the mid-frequency of the second frequency sub-range and from which the second frequency sub-range is obtained is inserted between the connection point of the direct-axis resistors and earth. A high broadband return loss is thus achieved so that even adjacent or overlapping frequency sub-ranges can be divided. Furthermore, the feedback from defective terminations of the output for the second frequency sub-range onto the input and the other output of the frequency filter is reduced and the component cost is extremely low, whereby the frequency filter is on the one hand inexpensive and on the other so small that it ... without difficulty in antenna sockets in the antenna socket housing ...

Title: Process and plants for purifying flue gases
Inventor: JAVAD MEHDI HAJI DR ING
IPC: B01D53/86
Filed: 1986-02-17
Abstract: The invention relates to a process and the necessary plants for reducing the NOx emission from furnaces, in which the flue gases are first substantially freed from accompanying materials, such as dust and SOx and the nitrogen oxides are then catalytically reacted by ammonia to give nitrogen and water. According to the invention, the dedusted and desulphurised clean gases are heated to the required reaction temperature of approximately 230-400 DEG C by indirect heat exchange with the flue gases from the furnace (in heat exchanger 1). After the NOx reduction, the clean gases are then cooled to the stack inlet temperature of approximately 80-100 DEG C by indirect heat exchange with the combustion air (heat exchanger 2). As a result, in comparison with the prior art, reheating of the clean gases by additional firing with expensive fuels (natural gas, heating oil grade EL) is dispensed with. Moreover, according to this invention, the operational reliability of the plant is improved and the capital investment and operating costs of the environmental protection equipment (filters, flue gas desulphurisation plant, SCR) are positively influenced. <IMAGE>

Patent DE-3615333-A1 (DE)
Title: Directing, deflecting and severing device
Inventor: KRAMM HARALD
IPC: B29B9/06
Filed: 1986-05-06
Abstract: In the production of granules (pellets) of plastic, strands of plastic are passed through cooling tanks which are open at the top. These strands are received in these cooling tanks and brought together. Water cooling and possibly air drying take place before the strands pass into a pelletiser. The severing and separate removal of not yet adequately solidified, inhomogeneous strands, the so-called preliminary material, present difficulties. This problem is solved according to the invention by a directing, deflecting and severing device in the form of a slide gate which is arranged in the discharge path and closes and opens an opening in the discharge path for removal of the feed material. When the slide gate is open, the preliminary material leaves through this opening and is collected. In the operating position, the slide gate abruptly closes this opening and severs the preliminary material. At the same time, the stabilised strands continue to be taken along on the discharge path, the slide gate representing part of the latter in the closed state.

Title: Method and arrangement for cooling coils and the laminated core of the stator of an electrical machine
Inventor: PANNEN EGON DR ING
IPC: H02K1/20
Filed: 1987-03-10
Abstract: The present invention relates to improved cooling of coils and the laminated core of the stator of an electrical machine, especially of a turbogenerator. Such a gas-cooled stator (1) having radial slots (8) (which lie in radial planes and through which cooling gas flows) between laminated core elements (7a, 7b, 7c) which are separated by spacer webs (6) is equipped according to the invention with additional slots (9) in the teeth (3), the additional slots extending essentially in the radial and axial directions, and their inlets and outlets communicating with the radial slots. In this case, parts of the flow of the cooling gas are diverted through the additional slots (9) by means of flow guidance walls (10, 11). The flow guidance walls (10, 11) can be constructed, in particular, such that they produce a ram pressure or suction. The cooling according to the invention enlarges the cooling surface and dissipates the heat from the interior of the teeth (3) without reducing the cooling gas flow in the radial slots (8) and without weakening the tooth heads by outlet slots. <IMAGE>
