Patent DE-19725886-A1 (DE)
Title: Multilayer, liquid-proof nonwoven fabric for roofing etc.
Inventor: BOICH HEINZ-HORST
IPC: D04H13/00
Filed: 1997-06-19
Abstract: A multilayer, liquid-tight nonwoven fabric (10) in the form of a composite material with at least two layers comprises spun-bonded fabric (12, 16) and melt-blown fabric (14), bonded/welded together by thermobonding at discrete points. The starting material for both components consists of polymer granules which are processed to give a liquid melt from which the fibres/filaments for the layers are made. The fibres (18) contain layer(s) of additives (20, 22) which reduce the wettability of the fibre surface by liquids with a surface tension so low that their contact angle without the additives would be from above 0 to below 90 deg , thus preventing penetration of fabric (10) by liquid. Additives (20, 22) are distributed throughout the fibre cross-section, and also on the fibre surface (18) as a result of diffusion.    Also claimed is a process for the production of spun-bonded or melt-blown layers for this fabric, comprising (a) production of additive granules containing "FX 18 01" (RTM: fluorocarbon compound), (b) mixing these with pure polymer granules and (c) processing the mixture to obtain the required melt liquids.

Patent DE-19726874-A1 (DE)
Title: Device for changing web tension in rotary printing machine
Inventor: ZUBER GERHARD
IPC: B65H23/188
Filed: 1997-06-25
Abstract: The tension is set by rollers whereby the roller (1) of constant circumference is driven at constant speed in dependence on the machine speed and is in direct contact with a contact pressure roller (3) which is coated with a rubber-elastic substance. The web (8) is looped round the contact pressure roller under tension and is moved by this roller slip-free. The contact pressure force of the contact pressure roller on the driven roller (1) and thus the circumferential speed of the contact pressure roller are variable. The diameter of the contact pressure roller is greater than that of the roller and the loop angle of the web is greater than or equal to 180 degs.
Patent DE-19732411-A1 (DE)
Title: Self-aligning system for racing cars
Inventor: SEEBECK NORBERT DIPL ING
IPC: B60K23/00
Filed: 1997-07-28
Abstract: The longitudinal axis of the vehicle seeks to align itself in the curves by means of a vertical fin (VF) with two oblique surfaces (SFH) at one third of the vehicle length and curve blades at the rear at a tangent to medium and fast curves. Two wheel couplings are mounted on the drive wheels or axes, the oblique surfaces arranged in the front part of the vehicle. The vertical fin (VF) and its oblique surfaces continuously seek a line tangential to the curve or straight ahead which in turn is enforced by the specified curve blades. The wheel couplings adapt wheel speed to the tangent of the curve and in braking maintain drive torque. In fast braking, the rotative drive torque is left unbraked as required at this speed.

Patent DE-19805412-A1 (DE)
Inventor: FISCHER UWE
IPC: B65H18/26
Filed: 1998-02-11
Abstract: Known contact roller systems of winding machines for winding running webs (1) of material such as paper or plastic films have several freely rotating roller segments (3, 3') which are mounted end to end adjacently to each other and which can move perpendicularly to their axis of rotation (11). According to the invention, each roller segment (3, 3') is held by a frame which moves perpendicularly to the axis of rotation (11). Each frame of a roller segment (3, 3') contains two side support plates (5, 5). Said support plates extend parallel to the ends of the roller segments and the adjacent support plates (5, 5') of two roller segments (3, 3') are located one above the other, perpendicular to the direction of movement. The support plates (5, 5) preferably have deep ring-shaped grooves (16) in which the end surfaces of the roller segments (3, 3') can rotate without contact. This arrangement enables each roller segment (3, 3') to be individually pressed against a winding roll (2) whilst keeping the gap between adjacent roller segments (3, 3') very small to avoid marks on the winding rolls (2).

Title: Process to remove and clean sand particles in a waste water treatment assembly achieves good separation of sand from other particles and operates at low cost
Inventor: LUELFING FRANK
IPC: B03B5/66
Filed: 1998-09-25
Abstract: In a waste water treatment process and assembly, incoming sand is separated from other substances and is washed in a combined process. Having been freed of coarse particles or solid objects, the water is agitated for a given time within a vessel which has number of fixed inner projections, and in which particles are separated by density. Floating organic substances are drained or skimmed, while sinking heavier particles are partly re-circulated. The sinking particles consist primarily of sand which is then exposed to a sand recognition sensor, and is extracted when positively recognized. A portion of the descending particles are removed at intervals by pumping and are returned to the water inlet or a preceding stage. The re-circulation process is initiated at a time when the lower zone is at rest. The sand recognition exploits the torque exerted on a mixer blade by an emerging sand particle.

Title: Method for controlling timing in IC engine
Inventor: TORNO OSKAR
IPC: F02P5/152
Filed: 1998-10-13
Abstract: A timing control for an IC engine monitors the change in engine torque and retards the timing if a first dynamic threshold value is exceeded. The control is improved by adding a second dynamic threshold value. This initiates a progressive advance of the timing while monitoring the onset of engine knocking. If knocking is detected the timing is retarded. The timing control is taken from a stored map and the control holds the timing between advanced and retarded setting for improved response.
