Title: Method and device for detecting and imaging objects and structures in enveloping scattering media by means of optical radiation
Inventor: HALLDORSSON THORSTEINN DIPL PH
IPC: G01V8/14
Filed: 1981-09-04
Abstract: The invention relates to a method and device for detecting and imaging objects and structures in enveloping scattering media by means of optical radiation. The medium is scanned by a sharply focused light beam (2). The light power (Pb) backscattered from the medium is detected in a receiver (17) and subsequently recorded along the scanning path. Objects (4) hidden in the medium (1) are detected by differential change in the received light power. Objects can be detected with respect to their extent and the depth of their position in the medium. It is preferred to use focused laser light having one or more specific wavelengths as the light. <IMAGE>

Title: Photographic camera equipped with a computer flash unit
Inventor: ETTISCHER HELMUT
IPC: G03B15/05
Filed: 1981-10-29
Abstract: A pivotable diaphragm member (4) having a small aperture (4c) and a filter lever (6) articulated thereon and equipped with a filter (6a) are effected by an exposure control device, depending on the ambient light, in such a manner that under low ambient light an electromagnet (2) retains the diaphragm member (4) via a retaining spring (1, 1a). By this means, a large aperture (5) comes into effect and the filter (6a) covers a light-sensitive element (7b) of the flash control, so that a full-power flash illumination is achieved. If the ambient light level is high, the diaphragm member (4) is not influenced by the electromagnet (2) and pivots under the action of the spring, so that the smaller aperture (4c) becomes effective. At the same time, the filter (6a) is pivoted in front of the light-sensitive element (7a) of the exposure control device and the light-sensitive element (7b) of the flash control device is exposed. By this means, an exposure time appropriate to the smaller aperture (4c) is produced. Reflected light from the flash acts in an undiminished manner on the exposed light-sensitive element (7b), by which means a partial flash illumination of a defined amount is produced as fill-in flash. The amount of flash illumination can be influenced by choice of the filter factor. <IMAGE>

Title: Method and device for operating a pulsed invertor
Inventor: KLAUSECKER KARL DIPL ING
IPC: H02M7/515
Filed: 1982-02-08
Abstract: On the basis of the known modulation method with a triangular waveform voltage for a pulsed invertor, an alternating voltage U(illegible) which is synchronous with the desired invertor output voltage is compared with a triangular waveform voltage U(illegible) and, if the two voltages are equal, generates a changeover signal for the invertor switch. The ratio k between the control voltage amplitude and the triangular waveform voltage amplitude is in this case proportional to the desired output amplitude in the region of relatively low output voltages. For relatively high output voltages, the ratio k is increased to be overproportional at values over 1. In consequence, especially in conjunction with a transistor invertor, fundamental oscillation amplitudes of the output voltage can be achieved which can be increased continuously to close to the maximum value which can be achieved with full-lock control. <IMAGE>

Title: Refrigerating machine
Inventor: SCHNADT FRIEDRICH ING GRAD
IPC: F25B49/02
Filed: 1982-09-17
Abstract: In a refrigerating machine with, connected in a refrigerant circuit, compressor 2, condenser 3, expansion valve 4 and evaporator 5, the expansion valve 4 is equipped with a temperature sensor 7 located on the refrigerant circuit. In order to facilitate the start of the compressor by means of a pressure compensation between the pressure side and the suction side, the temperature sensor 7 is assigned a heating element 8 which is switched on with the switching off of the compressor. A higher temperature is thus feigned to the expansion valve and its flow cross-section correspondingly increased. A rapid pressure compensation thus takes place so that the compressor 2 can be relieved from pressure after a short time, that is to say switched on with low starting capacity. <IMAGE>

Title: Method and device for indirect heat exchange
Inventor: RUFF KLEMENS
IPC: F23L15/04
Filed: 1983-03-30
Abstract: The invention relates to a method and a device for indirect heat exchange between at least a warm fluid flow 2, which over a given period changes essentially linearly from a low temperature level to a higher temperature level, and at least one fluid flow 5 that is colder relative thereto. A heat carrier flowing in its own circuit 3 serves as intermediate medium. The heat carrier circuit 3 connects two heat exchangers 1, 4 to which the warm fluid flow 2 is applied, on the one hand, and the colder fluid flow 5 is applied, on the other hand. Mutually independently connected heat accumulators 8, 9 are coupled to one another by a temperature comparison control 21, 28, 37 via in each case a feed line 10, 11 and a return line 12, 13 in the branch 7 of the heat carrier circuit 3 conducting the heated heat carrier. The temperature comparison control 21, 28, 37 enables the storage and dissipation of cold and hot quantities of heat carrier to the effect that the fluid flow 5 to be heated is uniformly heated and thus is available always at the same temperature level. <IMAGE>

Title: Vacuum cleaner with a suction hose and a control device
Inventor: STETTNER GERHARD DIPL ING
IPC: A47L9/28
Filed: 1983-04-07
Abstract: Attached to a housing 1 of a vacuum cleaner is a flexible suction hose 2 which bears at its free end a handle 3 for the connection of a suction nozzle 5. Situated in the handle 3 is a control device 6, 7 which is connected via a control line 8 to a further control device 9 in the vacuum cleaner housing. In order, in this case, to avoid electrical switching means outside the housing 1, the control devices 6, 9 are constructed as pneumatic actuators which are connected to one another via the control line 8 of hollow construction. Utilising the overpressure or negative pressure, prevailing in the vacuum cleaner housing, as control means, a complete electrical insulation can thus be achieved between the electrical control means in the housing 1 and the control device in the handle 3. <IMAGE>

Title: Safety interruptor with a monitoring device
IPC: H01H31/12
Filed: 1983-05-04
Abstract: The invention relates to a safety interruptor with a holding device which can be separated from the fuse lower part and supports the monitoring device. The contact blades of the NH fuse inserts which are suspended in the holding device make contact via round-wire spring brackets, which are constructed as a loop with a wave-shaped indentation in order to make contact. The ends of the loop form rotating springs with a plurality of turns and a spring limb which is passed out. The spring limbs are used for attachment of the spring brackets and for connection to the monitoring device. In addition, the rotating spring parts are held by means of insulated pegs of the holding device. The side curves of the loop of the spring bracket adjacent to the wave-shaped indentation are bent against the fixed contact of the fuse lower part so that, in the stationary contact region, the wave-shaped indentation of the loop is held at a distance from the stationary contact by the insulated electric-shock protection. Such spring brackets produce reliable contact-making even in the event of height differences of the fuse blades, associated with adequate voltage separation from the stationary contacts in the event of missing NH fuse inserts, bending of the spring brackets and the risk of hand injury being prevented.

Title: Method of mass-flow measurement
Inventor: NIED ROLAND DR ING
IPC: G01F1/76
Filed: 1983-07-30
Abstract: A method of continuously determining the mass flow of a bulk material is described, in which a mass-flow meter with a whirl gate through which the material flows is used. The method essentially comprises measuring the power consumption of the whirl-gate motor and converting it into a proportional voltage signal, and compensating for the component of this voltage signal corresponding to the power consumption during idling by a voltage signal derived from the continuous measurement of the mains voltage and set to the magnitude of the idling component. The measuring signal which results is then directly proportional to the mass flow.
