Title: Device for repairing potholes in asphalted roads
Inventor: FABRITZ GERHARD
IPC: E01C23/09
Filed: 1987-03-27
Abstract: The invention relates to a device for repairing potholes in asphalted roads. The device consists, according to Fig. 1, of a tubular shaft 1, at whose lower end cutting edges 2 are firmly inserted in corresponding openings 3. These openings are made radially in the tubular shaft at the same angle to one another and in the same axial planes. The cutting edges 2 consist of flat steel bent in the shape of a circular ring and can be hardened or coated with hard metal. The device is thus a kind of milling cutter. The latter is driven by a tube motor 5 which is fixed on the tubular shaft 1 and, for its part, is fixed on a three-dimensionally movable crossmember 6 of a corresponding vehicle. When the device is brought above a pothole, the latter can be milled out down to the substructure of the asphalt layer and it can be filled with a layer of suitable material of uniform thickness and compacted. During the repair of a pothole, milled-off material can be sucked up through the holes 4 situated in the region of the cutting edges 2 and the lower opening of the tubular shaft at 1' by means of an exhauster which is connected to the top of the tubular shaft. Fig. 2 is a section along the line A-A of Fig. 1 and shows the radial arrangement of the cutting edges 2, twelve cutting edges being used in this exemplary embodiment. <IMAGE>

Filed: 1987-06-10
Abstract: Chlorosulphonyl isocyanate is prepared by first metering hydrogen cyanide into the lower portion of a cyanogen chloride reaction column (36), into which chlorine gas is passed from the bottom. The cyanogen chloride reaction column (36) is connected to a scrubbing column (3), which is sprayed with water from the top. While the major portion of cyanogen chloride is being discharged at the top of the scrubbing column, water containing cyanogen chloride is passed from the lower portion of the cyanogen chloride reaction column (36) to the upper portion of a decoction column (8). On top of this column, a condenser (12) is present from the top of which the cyanogen chloride driven off flows into the lower portion of the scrubbing column (3). The upper portion of the scrubbing column is connected to a plurality of drying agent containers (14) which, in terms of flow, are connected in series. A line through which pure, dry cyanogen chloride flows leads from the last drying agent container to a CSI generator (16). The CSI generator (16) is fitted with a crude CSI column (17) which at its upper end carries a fraction divider (18) and on top of it a crude CSI condenser (19). A line leads from a sulphur trioxide container (20) via an evaporator (23) to the CSI generator (16). The condensate leaving the fraction divider (18) runs via a line into a pure CSI distillation flask (27) which is fitted with a pure CSI column (19), a pure CSI fraction divider (30) and on top of it a pure CSI condenser (31). Pure chlorosulphonyl isocyanate (CSI) is discharged through the product line (33).

Title: Hydraulic power-steering system, in particular for motor vehicles
Inventor: ELSER DIETER
IPC: B62D5/24
Filed: 1987-06-19
Abstract: A power-steering system has a working piston (14) which is installed in the transmission housing and engages with a threaded spindle (4). The working piston (14) drives, via a toothing (16), a steering shaft (17) which bears a steering segment (18). A rotary slide rail (6) which interacts with a control bushing (7) of the threaded spindle (4) is provided on a steering spindle (1). A reaction piston (3) is supported on the steering spindle (1) via a central centring device (2). An axially sprung corrugated tube (44) is installed between the reaction piston (3) and a bushing (43) which is fixed to the threaded spindle (4). In the event of rotation of the steering spindle (1) in relation to the threaded spindle (4), the V-shaped rotations (40, 41) rotate with respect to one another so that rollers (42) push a centring element (38), and with it the reaction piston (3), to the left. The corrugated tube (44) absorbs the axial displacement of the reaction piston (3) in a sprung fashion. The axial force exerted on the reaction piston (3) by the corrugated tube (44) has added to it a hydraulic pressure force which is dependent on the working pressure and acts in a reaction space (47). This pressure force exerts an additional restoring moment, via the reaction piston (3) and the central centring device (2), counter to the direction of rotation applied to the steering spindle (1). <IMAGE>

Patent DE-3729982-A1 (DE)
Title: Photoelectric web-edge control for the lateral guidance of webs of transparent materials
Inventor: KESPOHL PETER DIPL ING
IPC: B65H23/02
Filed: 1987-09-08
Abstract: In the web-edge controls known hitherto, a photoelectric sensor is used for sensing the web edge. If transparent-material webs are processed, the sensor has to be adjusted manually to the material transparency in order to sense the web edge. This compensation has to be repeated for each change of material transparency. In the web-edge control according to the novel process, the adjustment to the material transparency is carried out automatically. Two additional photoelectric sensors are used to register the respective material transparency irrespective of the position of the web edge. These signals are then processed electrically to produce a signal which is independent of the material transparency and which changes in proportion to the web-edge position. The novel web-edge control is suitable for the lateral guidance of webs of transparent materials. In the event of changes to the material transparency, the control does not have to be re-compensated.

Title: Reservoir for a rotary processing (development) device
IPC: G03D3/06
Filed: 1987-09-30
Abstract: The reservoir (31) for a rotary processing device serves to provide the liquid chemicals in a manner fit for processing. This is done by an electric jacket heater (6) which, interacting with a temperature sensor (8), tempers the liquid. A built-in agitator (1) stirs the liquid in the reservoir so that no differences in temperature can occur inside the liquid. The reservoir (31) can be evacuated via a built-in medium line (5). A conical seal (14) makes it possible to connect the medium line (5) in the reservoir (31) in a releasable, gas-tight manner to the medium line (5) in the foundation (13). The reservoir (31) is held in the correct position on the foundation (13) by an excentric (9) or with the aid of a latching detent (10) via a coding device (12). The level measuring device (2) can determine the respective level of the reservoir (31) in that the movement sequences of the float (4) cause a rotary movement of the counting disc (3), and the coding marks on the counting disc (3) are then evaluated. The power supply to the level measuring device (2) built into the lid (56) and to the agitator (1) is carried out via the electrical contacts (11). Liquid is taken from the reservoir via the container valve (7). <IMAGE>

Patent DE-3738311-A1 (DE)
Title: Overload clutch
IPC: F16D7/08
Filed: 1987-11-11
Abstract: An overload clutch has an input shaft and a coaxial output shaft with clutch elements at their ends with rolling elements projecting axially beyond the front faces mounted in them. The rolling elements of one clutch element reach between the rolling elements of the opposite clutch element such that, after an overload, torque transmission can be effected purely by their mutual contact. The rolling elements in one of the clutch elements rest against a sliding member supported in a manner which allows it to be displaced axially counter to the action of a spring, the clutch element opposite the clutch element with the spring-loading elements being supported axially to allow it to accept the spring forces in the case of an overload. A stop (4, 5) is provided to limit the sliding path of the sliding member (22, 25) towards the opposite clutch element (6), which is arranged in such a way that when the rolling elements (19, 20) supported on the sliding member (22, 25) rest against the opposite clutch elements (6), they are no longer spring-loaded. The support for the opposite clutch elements (6) is designed as a thrust bearing (7). <IMAGE>

Patent DE-3801383-A1 (DE)
IPC: B07B1/22
Filed: 1988-01-19
Abstract: The subject of the invention is a drum screen for conditioning and classifying granular material with an input device at the one end of the drum which rotates about its lying longitudinal axis and an output device for the conditioned material at the other drum end. The output device connects to an annular space which is formed between the drum and annular screen sections which are located one after the other in the longitudinal direction of the drum and concentrically surround the drum. The mesh width of the annular screen sections changes in such a way that the section with the smallest mesh width is the annular screen section nearest to the output device and the section with the largest mesh width is the annular screen section at the greatest distance from the output device, preferably located in the region of the input device. Between every two successive annular screen sections (7a, 7b), a channel-shaped profile (29), with the open side directed outwards, concentrically surrounds the drum (2) at a distance of the width of the annular space. The profile engages with a number of hook- shaped mounting elements (28), distributed over the circumference, over the respective profile flange of the annular screen sections ending at it, the annular screen sections being located with initially still extended hook parts (28b) essentially free of play between two channel profiles spaced in the longitudinal direction of the drum and being held after installation in the installation position with the hooks bent about the free flange ends during installation. <IMAGE>

Title: Paraglider formed from flexible material
Inventor: GLOECKL HANS
IPC: B64D17/02
Filed: 1988-05-04
Abstract: A paraglider (1) which is formed from flexible material, has upper and lower sails, and has ram-air chambers, also known as cells, which are formed between said sails and are open to the incident flow. In regions which are important for shape stabilisation, for example along the front upper and lower air-inlet edge (5, 5a), along the central ram-air chamber between the cell wall and the upper sail (6), and along the side stabilisers (7), the paraglider is provided with inflatable, flexible moulded bodies. These flexible moulded bodies are inserted into cavities formed by the parachute material, can be replaced if required and are normally inflatable before take-off. When the hoses are in the empty state, the parachute can be reduced to its normal packing volume. In one design variant of the paraglider, the distance between the leading edge of the upper sail and the leading edge of the lower sail is kept constant by means of elastic shaped bodies (16) which are fitted along the leading edge of the cell walls. The paraglider can also be reduced to its normal packing volume in this design. <IMAGE>
