Title: Tubular shrunk-on cover or shrunk-on sleeve for grips of sports equipment and articles of daily use such as tennis rackets, bicycle handlebars and the like
Inventor: KOTYGA MANFRED
IPC: A63B60/14
Filed: 1988-09-16
Abstract: Cylindrical covering material for grips of sports equipment and articles of daily use, such as tennis and squash rackets, bicycle handlebars, tool grips and the like. The grip covering of sports rackets, inter alia, is usually carried out by using grip ribbons or flexible fabric tubes. Characteristic of both methods is that they form only a latent connection with the grip substrate, wear quickly and are not very easy to put on for the inexperienced. In addition, the commercially available soft grip ribbons guarantee a secure grip position only until a given degree of moisture is reached. The new grip covering is to form a firm connection with the grip substrate, exhibit moisture-absorbing and adhering properties, be easy to put on and exhibit high material strength. To give the grip cover a secure hold on the grip substrate, and also to achieve a secure grip position of the hand on the surface of the grip cover, a cylindrical, knitted or woven covering material, which contains water-shrinkable connecting and/or main yarns and moisture-absorbing and/or adhering gassed cotton yarns or surface yarns, is pushed over the object to be covered and subsequently shrunk on by the addition of water and dried. The covering material is suitable for putting on raw grips of tennis rackets and the like - even after their hand-ergonomic shaping - and also ... Original abstract incomplete.

Patent DE-3916640-A1 (DE)
Title: Motor vehicle brake system with anti-skid unit
Inventor: SCHIEL LOTHAR DIPL ING
IPC: B60T8/90
Filed: 1989-05-22

Title: Waste glass bottles recycling - using distributor identifiers for three colours and recycling of non-aligned bottles
Inventor: KOPPELBERG HELMUT
IPC: B07C5/342
Filed: 1989-10-24
Abstract: Waste glass articles, esp. bottles, are first individualised in a single file and passed to colour sorting stations, each with its own ejector.  This is assisted by an overflow sepn., such that when the bottles lie on top of each other or side-by-side, the upper or lateral one will be recycled by another conveyor to the incoming flow.
