Title: Anti-slip and anti-skid device for vehicle tyres
Inventor: SCHAFMEISTER BRUNO
IPC: B60C11/16
Filed: 1987-05-26
Abstract: Known anti-slip and anti-skid devices for vehicle tyres have the disadvantage that if the road is not covered with snow and/or ice they subject the road pavement to high stresses and even wear it away so that devices of this kind in the form of spikes have been prohibited. Snow chains which are still permitted as an alternative are difficult to fit and adversely affect driving behaviour, in particular on a road pavement which is free of snow. It is thus intended only to use the new device if the vehicle is travelling on snow and/or ice. The new device has pins or claws which are attached so as to be capable of being extended and retracted as desired, either controlled from the driver's seat or automatically so that they protrude from the tread of the vehicle tyre as long as they are required but are otherwise retracted and thus remain inactive. The device ensures anti-slip and anti-skid protection when a vehicle with such tyres is travelling on snow and/or ice but does not damage the roadway pavement when it is free of snow and ice.

Title: Method for operating yarn-processing devices
Inventor: FRENTZEL-BEYME JOHANNES DIPL I
IPC: D01H1/42
Filed: 1988-05-24
Abstract: A method for operating yarn-processing devices, in which is formed a thread balloon which, during the normal operation of the device, comes into contact, at least on parts of its circumference, with surface regions of the device, for example a balloon limiter, which limits its free expansion. Varying states in the case of superficial deposits of viscous fibre accompanying materials on the surface regions not normally touched by the thread balloon lead to yarn changes in the event of fluctuations in the balloon shape. This is prevented in that, during the processing process, one or more operating conditions are varied at predetermined time intervals for a predetermined time segment, in such a way that the thread balloon comes into contact with different surface regions from those during normal operation. This ensures that, even in the event of fluctuations in the balloon shape, the thread always strikes approximately identical surface regions produced by itself.
