Patent DE-19837180-A1 (DE)
Title: Condensing apparatus for drawn sliver consists of rotating perforated disk with end sliding surface on rotary axis at right angles to sliver and axes of paired take-off rollers
Inventor: LANG KURT
IPC: D01H5/28
Filed: 1998-08-17
Abstract: The condensing zone for drawn sliver has a sliding surface with a suction slit to generate a suction air flow. The sliding surface (21) is the smooth end surface of a rotating disk (20), on a rotary axis (26) at right angles to the sliver (10) and to the axes of the paired take-off rollers (11).  The diameter of the disk (20) matches the gap between the roller clamping lines (15,16) at the paired take-off (11) and entry (2) rollers. The suction slit is as wide as possible at the clamping line of the take-off roller pair (11), and the suction slit width is wider than the width of the drawn sliver (10). The suction slit runs parallel to the circumference of the disk (20), at least at the rotary axis (26) zone. The disk (20) has a number of holes (22), with a diameter of 0.5-0.8 mm. The disk (20) can be detached easily from its rotary axis (26). The disk (20) rotates with a surface speed at the suction slit which is significantly faster than the speed of sliver (10) travel. The sliding surface is coated, such as with a nickel-diamond material.

Title: Safety system for total monitoring of rail stretch and rail vehicle travelling on it has several measurement circuits, closed in themselves and distributed in decentralized fashion
Inventor: ZAHRADNIK JIRI
IPC: B61L23/04
Filed: 1998-09-15
Abstract: A safety system for total monitoring of a rail stretch and a rail vehicle travelling on it has several measurement circuits, closed in themselves and distributed in a decentralized fashion, communicating with each other and each having one or more measuring points with different measurement sensors. At these upon activation of the measurement circuits (1-3), actual values of differing parameters can be tapped off independently. There are one or more central control units of two sorts in which these actual parameters are compared with data profiles on set point parameters which are generated and stored for each section of the rail stretch with regard to their respective constructional properties and the operational properties of the rail vehicle (4) to be prevailing. All this is to allow a correct elapsed-time classification of the actual parameters for back-tracking a cause of a disturbance occurring not only in the course of the rail stretch but also on the rail vehicle so as to introduce corresponding control measures in real time.

Title: Pressurized lignite drier has input feed progressively raising air pressure and discharge pipe with progressively lowering pressure for compact assembly
Inventor: KROEDEL BERND
IPC: F26B3/08
Filed: 1998-09-10
Abstract: A bulk grains mechanical handling system maintains a feed of moist brown coal (1) grains and lumps to a pressurized furnace operating at 5 to 20 bar. The coal is released to a trunk (3) formed by an enclosed pipe chain-conveyer in which the pressure is increased by stages as the conveyer advances towards a pressurized fluidized bed drier (10). The incoming coal is released within the upper zone of the pressurized fluidized bed drier, distributed through the fluidized bed (5). As it falls, the coal impinges on several deflector baffles (9) and forms a heap (7) in the funnel-shaped base zone within the drier. The dried coal is then lifter from the base of the heap by a chain return conveyer (12) pipe in which the air pressure is reduced step by step. The dried coal is then released into a fuel silo (14) where it is stored pending use.
