Patent DE-3601201-C1 (DE)
Inventor: MENTE KURT
IPC: D04H3/03
Filed: 1986-01-17
Granted: 1987-07-09
Abstract: In the production of irregular non-woven material sheets of synthetic filaments, the warp from spinnerets is drawn off by means of a draw-off device and then deposited on a substrate. To avoid tangling of the individual filaments, they are guided along a nozzle wall formed by slot nozzles stacked on top of each other and forming a draw-off device. The slot nozzles as well as the air compressor are operated polytropically. The deposit of the warp on the substrate is accomplished by a flip-flop cross winding.
Patent DE-3609941-C1 (DE)
Title: Sisal leaf cutting implement
Inventor: STEINCHEN WOLFGANG PROF DR-ING
IPC: A01D45/06
Filed: 1986-03-24
Granted: 1987-08-06
Abstract: The invention is based on the object of cutting all the ripe leaves simultaneously from those leaves growing out around the circumference of the sisal plant stem. Leaves are cut which either grow horizontally out of the stem or form an angle therewith of up to approximately 45 DEG . The diameter of the stem of an ordinary sisal plant is between 300 mm and 400 mm. The object of simultaneous cutting of several sisal leaves is achieved according to the invention in that the annular or circular arc-shaped implement is adapted to the minimum stem diameter of 300 mm. For cutting the leaves on the larger stem diameter, the two circular arc-shaped arms of the implement, consisting of individual members connected by joints, are adapted to the larger stem diameter by simple manual actuation (Figure 1). The two circular arc-shaped arms are connected in an articulated manner and are driven in an oscillating manner by a crank. The advantages achieved by the invention consist in the fact that several sisal leaves can be separated from the stem with few oscillating cutting movements of the saw blade. <IMAGE>

Title: Lip seal ring
Inventor: HESSE EDWIN DIPL-ING
IPC: F16J15/00
Filed: 1986-03-26
Granted: 1987-06-04
Abstract: In a lip seal ring for sealing rotating shafts with a runner ring and preferably at least two sealing lips, arranged axially next to each other, the runner ring is axially displaceable. Directly after installation, the first sealing lip rests with sealing force on the runner ring, and, directly after installation, the second or further sealing lip is functionless, without contact with the runner ring. Only after displacing of the runner ring is the second sealing lip pushed onto the runner ring surface with radial force such that it is resting on and sealing the latter, so that in the event of a repair after wearing of the first sealing lip or runner ring surface the damage can be rectified in a simple and cost-saving way without major installation work. <IMAGE>

Patent DE-4203987-C1 (DE)
IPC: C04B40/00
Filed: 1992-02-12
Granted: 1993-08-05
Abstract: Concrete or reinforced-concrete basins for storing, treating or channelling hazardous liquids or drainage water containing such liquids are usually coated on the inside with a composition which is sealed and resistant with respect to said liquids. This very expensive coating is replaced according to the invention by a special concrete, which, for its part, is already resistant with respect to such substances. This concrete contains an additive of silicate dust, the grain size of which is, for the most part, equal to or smaller than 0.125  mu m. The setting of the special concrete can be delayed by conventional measures, e.g. by applying a water-soluble impregnant.

Title: Land vehicle friend-foe identification device
Inventor: SCHERBER WERNER DIPL PHYS DR
IPC: G02B5/124
Filed: 1992-12-19
Granted: 1996-01-18
Abstract: The device responds to a masked infrared marking which is only visible to friendly observers. The object carries large format heated image elements with a low degree of thermal emission. The heating elements are controlled so that the apparent temp. of the image elements corresp. to the true temp. of the vehicle surface surrounding the markings so that the markings are not visible to a normal thermal imaging device An infrared laser on the observation side , esp. a CO2 pulse laser, is used to illuminate the object. An infrared camera, whose image field is coupled to the alignment of the laser, can be synchronised with the laser to generate a standing image, from which an epsilon-image pattern can be read if present.

Title: Hydraulic unloading system for snowplough mounted on vehicle - has hydraulic circuit control correcting actual pressure in ram on deviation from set value
Inventor: THANNER WERNER
IPC: A01B63/11
Filed: 1993-02-11
Granted: 1994-05-19
Abstract: The circuit contains a hydraulic accumulator (25). When unloading, and initially where the pressure in the accumulator and/or that in the pressure chamber (13) of the ram is below the desired unloading pressure and then rises, a valve (17) is automatically changed over to the unloading position, detaching the vehicle part of the circuit from the unloading one, and the accumulator is connected to the ram pressure chamber. As the actual value of the unloading pressure rises above the desired one, the valve is changed over into the overload position at least briefly, connecting the vehicle part of the circuit, which is under pressure, to the accumulator. The valve changeover from unloading to overload, lowering the pressure while cutting in the accumulator-charging circuit (0) is by hysteresis. USE/ADVANTAGE - Hydraulic system reduces load on ploughshare due to weight and scraping road surface, and can be cut in and out as desired, while maintaining predetermined unloading pressure.

Title: Line threader
Inventor: BERTRAM KLAUS DR MED
IPC: F16G11/10
Filed: 1993-08-17
Granted: 1994-09-15
Abstract: A device for laying a line around a remotely arranged bar, a ring section, etc., is described. The device has a retaining rod, on the front end of which a lay-around part is arranged which has an openable and closable sectional ring to which the front end of the line to be laid around the bar can be fastened. The two ends of the sectional ring are displaceably mounted between a first and second end position in or on a guide arranged on the retaining rod. By displacement of the sectional ring relative to the guide, a bar around which the line is to be laid can be inserted into the space between sectional ring and guide and can be led out of this space again, the line being laid around the bar. The sliding guide between guide and sectional ring ensures a simple, easy and functionally reliable mode of operation. <IMAGE>
