Title: Method and device for controlling the water supply to a steam generator
Inventor: SPEIDEL VOLKER
IPC: F22B1/28
Filed: 1993-02-16
Abstract: The present invention relates to a method and a device for controlling the water supply to a steam generator, which is supplied in a temperature-controlled manner, with the aid of a pump (7), with the evaporated amount of water by water flowing behind. To this end, a temperature sensor is connected in heat-conducting fashion to the heating element (3) and the supply line (5) and conveys the measured temperature to a thermostat (6) which, in turn, switches on the pump (7) in dependence on the temperature present in each case for such a time until the temperature sensor (4) is cooled with the aid of the water (5) flowing behind to a given temperature and the pump (7) is switched off again by the thermostat (6). <IMAGE>

Title: Transporting hopper for plastics granulate
Inventor: POTTHOFF RUEDIGER
IPC: B29C31/02
Filed: 1993-02-26
Abstract: The purpose and object of the invention is the uninterrupted transportation of the plastics granulate from the manufacturer to the plastics machine of the user to produce shaped and profiled products made of plastics. Transferring granulate causes loss of time and granulate, in particular in the case of suction equipment. Owing to the special shape of the bottom of the transporting hopper, complete extraction of the granulate without residue is guaranteed, thus allowing automatic operation with a very variable arrangement adjacent to the processing machine in plastics production.

Title: Closable container for storage, for transport and for separation
Inventor: BURGHARDT AXEL
IPC: B65F1/16
Filed: 1993-03-11
Abstract: A container with a closable lid for the storage, transport and separation of materials which are mixed with or affected by liquids which are hazardous to the environment. A dumping container of a known design is provided with a double bottom (7, 8), connected tightly to the outer walls (9), in the form of an inner trough and, in this way, has a dead space (10) which collects the leaking fluid in the event of damage to the inner trough and prevents the fluid from entering into the bottom. Containers of this design can be set up in a free-standing manner. An inspection nozzle (18) which is closed in normal operation allows this dead space to be checked and to be emptied if required. An inserted filter system (12, 13) separates solids which remain in the loading space (16) from the liquid which collects in the separation space (17). A drainage valve (6) which is connected to the separation space (17) allows the liquid to be drained off and thus allows transportation without risk. The hinged lid (2, 3, 4) prevents the entry of rain water and can be opened by means of a crank/lifting mechanism (5) such that the container is fully accessible from three sides. <IMAGE>

Title: Non-destructive testing of concrete by confocal magnetic tomography
IPC: G01N27/82
Filed: 1993-12-10
Abstract: A method for the non-destructive testing of a reinforced / prestressed concrete building structure employs confocal magnetic tomography to obtain images of the magnetic distribution in planar fields at selected distances from the outer face of the structure. A magnetic sensor in a measurement plane (3) registers the combined effects of a magnetic source plane (2) incorporating the prestressed members (not shown) and a plane (1) nearer the concrete surface in which reinforcing rods (not shown) superimpose an unwanted distortion. Such distortion is suppressed by suitable filtration in order that faults/irregularities in the prestressing structure are reliably detected by a real-time Fourier transform programme.

Title: Sorting machine for waste paper and cardboard
Inventor: THUST WALTER DIPL ING
IPC: B07C5/36
Filed: 1994-05-17
Abstract: The sorting machine involves a material separator (2) and a sensor to classify the sorted material. It has two perforated conveyor belts (6,8), one of which (8) is driven faster than the other (6). A suction chamber (14) beneath the upper run of each belt sucks air through the perforations, holding pieces with large contact area against it, and with other pieces sliding off. The slower belt slopes upwards and the faster belt slopes upwards less steeply. A feeder belt (4) feeds the slower belt, where its discharge end is at a set distance from it, and which has a vibrator (5). There is a yet faster conveyor belt (10), which leads to a further split parallel conveyor belt with visual sensors e.g. video camera, and beating part protruding between the parallel belt parts to strike an item, with microphones sensing the quality of the sound produced. The sensor outputs are used to judge the type of material which is accordingly conveyed to different containers.

Patent DE-4419307-A1 (DE)
Title: Hysteresis brake for adjusting braking force in fixed training devices and ergometers
Inventor: FISCHER STEFAN
IPC: A63B21/005
Filed: 1994-06-01
Abstract: In program-controlled braking force devices of fixed training devices and ergometers, in particular those with an eddy current brake, the braking torque to be set can only be controlled precisely by taking into account the speed of revolution n. In addition, in the minimum range of speed of revolution almost no torque can be produced with such a braking device which requires increased technical complexity for specific applications. Using a hysteresis brake, it is no longer necessary to take into account the speed of revolution when controlling the braking torque since the braking torque in this braking machine no longer depends on the speed of revolution but rather only on the exciter current and can be adjusted infinitely from n = 0 up to the maximum value for the particular type. This technical innovation permits an improved and simplified adjustment of the braking force in fixed training devices and ergometers for demanding tasks, such as e.g. realistically simulating in a visual and functional way the loading when riding a bicycle along a natural stretch of road.
