Title: Mining device for the long front mining of stratified mineral raw materials underground
Inventor: BLUMENTHAL GUENTER ING GRAD
IPC: E21F13/06
Filed: 1985-04-20
Abstract: It is known in the case of short faces to integrate working, conveying and support in one device. In this case, it is a special support, a double-strand scraper flight conveyor as well as a continuous chain belt with, incorporated therein, loosening tools and carriers which revolve vertically on the face side of the scraper flight conveyor and on the face side of the roof members. The invention envisages in contrast arranging two support frames 24, 25 one behind another and displacing them relative to one another by pushing rams 46, 47. Connected pivotably to the front support frame 24 is a conveying trough 7. Articulated pivotably on the face side of the conveying trough 7 is a guide rail 8. The guide rail 8 is pivotable relative to the conveying trough 7. By means of the pushing rams 46, 47 between the support frames 24, 25, the face-side support frame 24 and with it at the same time the conveying trough 7 also as well as the guide rail 8 can be displaced. Guided in the guide rail 8 and in the conveying trough 7 is an essentially horizontally revolving chain belt 12 with, incorporated therein, loosening tools 10 and carriers 11. The face-side support frame 24 is shielded in relation to the stowing-side support frame 25 by a lemniscate guide arrangement 41. <IMAGE>

Title: Manufacturing method for producing models for design, development and planning
Inventor: KOBS GUENTER DIPL ING
IPC: G09B25/00
Filed: 1985-08-28
Abstract: New paths can be trod using the special modular system and the corresponding method when models are used for design, development and planning. These new possibilities do not just facilitate the manufacture of models, but are also kept sufficiently flexible to be able to be used to assist development and planning of buildings and installations. Extended and technically converted principles of observation make the structures "easier to grasp", so that conditions more conducive to the participation of a larger number of people in the joint solving of structural and technical problems are created. In the modular system, special working and drawing implements are displaceably arranged on a guide rail. Model-working tables are situated in front of them. Models can be quickly and easily manufactured using special appliances and tools and can at any time be adapted to the particular stage of development. Depending on the modelling material, work can be dust-free and almost without waste. This means that the system can also be used without problems in the office. <IMAGE>

Inventor: KNOBLOCH OSBERT RICHARD DIPL I
IPC: B02C4/28
Filed: 1985-10-03
Abstract: The invention relates to a method and a system for comminuting material for grinding by means of two rollers. In this method, the width of the roller gap is kept constant by controlling the material charging width which is effective in the drawing-in area of the rollers and/ôor the height of the material column which loads the rollers. In this way, even in the case of fluctuations in the material for grinding, a uniform specific throughput and a constant grinding effect are obtained.

Title: Plate gauge measuring instrument
Inventor: ROEHRER RALF DIPL ING
IPC: G01B7/06
Filed: 1985-11-15
Abstract: Magnetically based plate gauge measuring instruments have a relatively high measurement uncertainty. They are therefore used generally only where it is to be established whether one plate or a double plate is located under the measuring head of the instrument. In order to increase the measurement accuracy, it is proposed according to the invention that the coil of the measuring head, which can be used to determine the plate gauge via the current, is connected to a voltage of opposite polarity with respect to the measuring voltage after measurement until clearance of the total remanence.

Title: Mechanical pneumatic manipulation system for coloscopes (endoscopes)
Inventor: REINHARDT LUTZ
IPC: A61F2/958
Filed: 1986-02-19
Abstract: Coloscopes fitted with this system are no longer pushed but can be drawn further into the region to be examined after their introduction. For this, a mechanically displaceable system (principal system) is located on the coloscope shaft behind the controllable tip. It comprises an inflatable or ventable group of balloons (balloon) on a flexible sliding pipe. If required, the system may be supplemented by a group of balloons (balloon) firmly mounted on the coloscope shaft (auxiliary system). Considerable practical advantages result for diagnosis and therapy. Without the disadvantages of the conventional, pushed instruments (considerable time expenditure, assistant, radiological control, large problems in the regions known to be critical (sigmoid ..) and the associated pain) the doctor can pass unaided even through difficult regions without any problems while he controls the passage via the optical system and the movable tip. In addition, he can treat the patient alone with accurate control.

Title: Dust removal cyclone heated by a part stream of cracked gas, downstream of a low-temperature carbonisation drum
Inventor: FOERSTER REINHARD DR
IPC: C10B49/08
Filed: 1986-12-05
Abstract: The low-temperature carbonisation, known per se, of waste materials in a low-temperature carbonisation drum (1) heated indirectly by fuel gases can be improved, if the fuel gases are used exclusively for low-temperature carbonisation and do not additionally have to preheat a cyclone (5) for the separation of the low-temperature carbonisation gases from the pyrolysis residues, in order to prevent condensation of the low-temperature carbonisation gases in the cyclone (5), but if, instead, a part stream (18) of the low-temperature carbonisation gas (10), heated via a gas converter (11) to at least 1000@C, is passed through a housing (21) around the cyclone (5). In this way, the low-temperature carbonisation drum (1) and the cyclone can be designed independently of one another and, in particular, no gaskets are required on the outer periphery (1) of the rotary drum (1). <IMAGE>

Title: Process and device for liquid withdrawal from particle-laden liquids, in particular for dewatering suspensions or sludges and use of the process
Inventor: VOLLMAR HORST-ECKART
IPC: B09C1/02
Filed: 1987-02-07
Abstract: Previous processes for sedimentation of suspensions or sludges which contain magnetisable particles only utilise the gravitational forces and therefore work relatively slowly with low sediment densities. The sedimentation time is to be decreased and the sediment density increased by means of the novel process. The particle-laden liquid is introduced on a feed side into a sedimentation chamber (5.1), at least one expansion direction of the sedimentation chamber agreeing with the desired sedimentation direction (16a) of the particles. The volume of liquid contained in the chamber, apart from the gravitational field, is exposed to a strong magnetic field gradient, the force vectors and field gradients of which run in or substantially in the sedimentation direction (16a), so that the magnetisable particles are driven in the direction of increasing magnetic field strength and are compressed to form a sediment cake (10). The device for carrying out the process is provided with a vessel (70) for the sedimentation chamber (51), surrounded by at least one solenoid (100) of a superconducting magnet (SLM) and including a feed chamber (23) for the suspension and a discharge zone (230) for the sediment having a conveying element (26), and in addition a take-off orifice (27.1) for the settling liquid. The use relates to the sedimentation of iron hydroxide or iron-hydroxide-containing heavy metal hydroxides. <IMAGE>

Title: Thermostatic valve for the coolant of internal combustion engines
Inventor: WAHLER HANS DIPL ING
IPC: G05D23/13
Filed: 1987-04-09
Abstract: The invention proposes a thermostatic valve for the coolant of internal combustion engines which has a control device with two axially adjacent plate valves, one of which controls the flow from the inlet to the outlet and the other controls the flow from the inlet to the bypass for the coolant. Each plate valve has a supporting plate and a valve plate which is pressed axially against the latter, each of these plates consisting of ceramic material and both of them being turned by a common adjusting shaft which is acted upon directly by an electric stepping motor. In one direction of rotation, this motor operates against an opening spring acting in the opening direction of the first plate valve between the inlet and the outlet. If the stepping motor fails, this opening spring moves the adjusting shaft automatically into the open position and overheating of the internal combustion engine is then avoided.
