Patent DE-4106497-A1 (DE)
Inventor: WIRGES GERHARD O
IPC: F04D13/02
Filed: 1991-03-01
Abstract: The invention concerns a power-generator unit comprising a drive motor and a generator, intended in particular for motor vehicles, a coolant pump on a shaft being fitted between the generator and drive motor. The shaft is preferably designed in two parts and can preferably be connected up to a conical-joint socket. The coolant pump is designed as a centrifugal or magnetic-rotor pump.

Title: Shutting off flow in high pressure pipes remote from danger area or pipe end - uses circular cutter in support housing and shaft and valve, suitable for medium being carried by pipe or oil well probe
Inventor: VOELK HANS DIETER
IPC: F16L55/105
Filed: 1991-05-06
Abstract: Shutting off the flow can be achieved by either making a transverse cut into the pipe and using the cutter as a valve. A split socketed pipe forms a housing and support for a hydraulically driven circular cutter, the shaft of which forms a sleeve valve in the pipe, provided the shaft is of the same dia., as the pipe being cut into. A further development enables injection of pipe sealant through an angled branch in the socketed pipe. Sealing material can be pumped in agains the fluid flow in the pipe via a valve. Multiwalled pipes are sealed by injection of sealant. ADVANTAGE - Cost effective means of shuttting off pipes remote from pipe end, in situations where high pressure or fire make it dangerous to work at the delivery end. Uses simple equipment which is easily handled.

Title: Towing device attachment on vehicle - has mounting bracket weak in bending at point of attachment to vehicle, allowing designed crash deformation of chassis
Inventor: BREITINGER REINHARD DIPL ING
IPC: B62D25/20
Filed: 1991-05-15
Abstract: The towing device on a vehicle has a mounting bracket (4) comprising a clamping eye (5) and arm (6). It attaches at one end (7) to a chassis length (1) of the vehicle, and runs at an angle to the chassis axis. Near to the point of attachment (7) on the chassis (11), the mounting bracket is relatively weak in bending A strut (12) between the chassis and mounting bracket supports the mounting bracket when towing. In the case of a crash, an increase in the angle between the arm and the strut, due to the mounting bracket swinging out of the way, allows the desired deformation of the chassis. USE/ADVANTAGE - Tow hitch on vehicle does not hinder designed crash deformation behaviour, particularly of the chassis end region.
