Patent DE-3830874-A1 (DE)
Title: Pipe coupling
Inventor: MUECHER HORST ADOLF
IPC: F16L21/00
Filed: 1988-09-12
Abstract: The pipe coupling (14), which consists of a sealing sleeve (5), serves for the leak-tight connection of the spigot ends (1 and 1') of two pipes used to convey media to which the material of the elastomer sleeve (6) of this sealing sleeve (5) is not sufficiently resistant. To obtain a resistant pipe coupling (14), an independent layer (4) composed of a particularly resistant material is arranged between the outer wall of the spigot ends (1 and 1') and the sealing sleeve (5), this layer being pulled onto these two spigot ends (1 and 1') when assembling the pipe coupling (14), before the sealing sleeve (5) is pushed axially over the layer (4) or laid around the latter. According to a further development, the mounted layer (4) can be under elastic prestress allowing the reliable sealing of spigot ends (1 and 1') of pipes with different tolerances using conventional/standard and therefore inexpensive sealing sleeves (5). <IMAGE>

Title: Two-speed lever drive for wheelchairs
Inventor: OLBRICH GERHARD
IPC: A61G5/02
Filed: 1989-01-17
Abstract: The conventional lever drives do not have any gear shifting. The drive can only be interrupted if the adjustment at the connecting rod (2) is opened. The drive mechanism (3) continues to rotate on pushing of the wheelchair. The new gear drive is shifted and made to run freely by the selection lever (4). By throwing over the brake lever (5) the wheelchair is braked to an extent that can be selected. In the free running position "b", the drive lever (1), the connecting rod (2) and the drive mechanism (gear) (3) are at a standstill on rolling of the wheelchair. The first speed is obtained in the position "a" of the selection lever and the second speed is obtained in position "c". In a forward and backward stroke of the drive lever (1) the drive wheel (6) moves about its circumference at the first speed. At the second speed, this depends on the gear transmission. On standstill in the dead angle (A or B) a new drive angle is chosen by shifting into free running. By this design the drive, brake, free running and gear can be shifted with one hand without lifting the hand from the drive lever. The drive is suitable for wheelchairs with one-arm or two-arm drive. The gear furthermore makes it suitable for patients with weakness of the arm muscles. <IMAGE>
