Patent DE-19741440-A1 (DE)
Inventor: JUNG THOMAS
IPC: F16H37/04
Filed: 1997-09-19
Abstract: A gearbox, in particular for motor vehicles, has an input shaft (14) and an output shaft (16), as well as a first torque-transmitting device which is arranged between input and output shafts (14, 16), makes possible various transmission ratios and, in one mode of operation, totally interrupts force transmission from the input shaft (14) to the output shaft (16). The object of the invention is to provide a cost-effective gearbox with an automatic mode which can transmit high torques and avoid a total load interruption during gear shifts or changes in transmission ratio. This object is attained in the above-mentioned gearbox in that a second torque-transmitting device (40, 42, 44, 46, 48, K) is arranged parallel to the first device between input and output shafts (16) and transmits, unlike the first device, a selectable torque which is continuously variable from near zero to its maximum possible value.

Title: Dry removal of coatings, graffiti and other soiling on flat or curved surfaces and process equipment
Inventor: PIEPER GERARD
IPC: B24C5/04
Filed: 1997-10-19
Abstract: The carrier air flow is produced by vacuum in an open circuit passing through the hose system (20,28) and a sealed cover (25) placed against the surface (3) being treated. 0.01-1.0% of abrasive is metered by gravity and/or vacuum into the air flow and the mixture is accelerated from 20-80 m/s before being moved to-and-fro across the surface. Used mixture and dust is sucked away and the abrasive separated, dried and remetered back into the air flow. Independent claims are also made for: a) the process equipment; b) use of various particulate materials for removal of paint, graffiti and other soiling. PREFERRED FEATURES: Acceleration is effected in a straight tube (21) either with a diameter reduction of 0.3-0.9 times the hose diameter (d1) and length (L) 5-30 times the internal diameter (d2) of the tube or without diameter change. Abrasive output speed can be varied by changing the diameter ratio (d2:d1) and/or tube length (L) and/or nozzle (24) distance (a) from the surface (3). Air flow is 150-400 cu m/h, preferably 230 cu m/h. Abrasive can be plastic particles, especially thermoset plastic particles, ash, fine particle clinker, corundum, quartz, metal particles, glass beads or mixture of these. The air supply hose line (20) is connected to the acceleration tube (21) and a tubular lance (22) which swivels through a 90 deg conical zone inside the cover (25). An abrasive metering device (18) connected to the mixture injector (19) is fed from a hopper (13) in a first container (11). Another container (10) on top of the first is fed with recycled air, dust and abrasive via a return line (28) and is connected to a vacuum unit (4). The cover walls (26) may be convex, concave or V-shaped or have joints to allow adaptation to different surfaces. Vacuum is produced at either a wet or dry vacuum unit, a pump, a compressor or a fan. Seals are located between the cover and the surface being treated.

Title: Procedure for moving trains in sections without overhead conductors
Inventor: SCHEIBEL GERALD
IPC: B61J3/12
Filed: 1998-01-09
Abstract: A procedure for moving trains in sections without overhead conductors has an electric locomotive with a coupled wagon train traveling in one direction (20) from a track in region A (26) covered by an overhead conductor into another region B (27). A shunting device coming region D (29) from a truncated track (31) in region F (33) which is a part of the previous track with overhead conductor, travels over the overhead conductor-free region C (28) into region B. At the end it couples to the electric locomotive with wagon train and moves this out of region B over region C into region D. In region D the shunting device uncouples from the locomotive with train and then travels into the truncated track in region F. The locomotive with train now finds itself on a track with an overhead conductor and travels out of region D into region E (30).

Title: Control equipment for charging generator in vehicle
Inventor: SEKIYA NORITAKA
IPC: H02P9/30
Filed: 1998-06-09
Abstract: The control equipment is for a charging generator with a short circuit protection circuit (5) which periodically supplies a reset pulse to a power transistor (51).

Abstract: A continuous fiber band(14) enters an extruder feed opening(18) parallel to and tangential to one of the two screw shafts and is coated with plastic film(10,11) from both sides, one side coated directly, the other indirectly. The coated rovings are then wrapped around the screw shafts(4,5) and driven forward in a feeding and impregnating section of the screw bores(2,3).

The bore diameter in the feeding and impregnating section is enlarged by  NOTLESS  four times the thickness(S) of the roving band(14). One or two coating dies(12,13) are located above the extruder barrel feed opening(18) which runs parallel to the screw axes(6,7). The discharge section has a cutting edge at the inlet and bores with reduced diameter compared to those in the feeding and impregnating section. Preferred Features: The plastic film coating(10,11) may also be applied from just one side of the flat roving band, either directly onto the band on one side or indirectly on the other side by pressing the roving band into a flat side of the film. The fiber band is wound several times around the extruder shafts(4,5) and driven forward. Band windings may overlap.

At least one station (3) where the layers are brought together is separated from at least one feed (4) for a material layer (2) through an assembly layout on different planes (12,13). All or most of the fabric supply rolls (16) are stored on the same plane (13) and unwound as a supply which is not part of the product production until moved into use. Other materials, which are not wound on rolls (16), are stored on a plane to be fed to the production stations (3) on their planes (12,13). The additional material can be flocking material and/or a super absorbent with a swelling agent (possibly based on an acrylic or cellulose type) and/or deodorant materials and/or odor dampening materials and/or glue or other adhesive bondings. There is a clear division between the production plane (12) with the workstations (3), and the other plane (13) which has the supplies of materials where the fabric webs and the non-fabric components are delivered from the floor level to the upper working level (12), or they are fed downwards to the workstations. The fabric webs (2) are unrolled from supply rolls (16) on axes parallel to the production plane (12) and/or across it.
