Title: Rope winch
Inventor: HENSGEN ROBERT
IPC: B66D1/50
Filed: 1981-11-24
Abstract: Arranged in front of a drum (1) for winding a rope (5) is a tensioning device (3, 4) which tensions the rope section leading to the drum. Bearing on the said rope section is a pressure roller (7) which can be displaced parallel to the axis of the drum (1) by means of a displacing drive (8). Connected to the pressure roller (7) is a feeling device (10, 11) which controls the speed and direction of the displacing drive (8) as a function of the drum approach angle of the rope (5). The arrangement has the advantage that the drum approach angle remains within the permissible limits even when using a wide drum (1) in which the tensile-force relationships do not change or only change slightly with the length of the wound-on rope. The arrangement only occupies a little space and can therefore also be accommodated in the interior space of a vehicle, e.g. in the interior space of a military recovery vehicle. <IMAGE>

Patent DE-3245902-A1 (DE)
Title: Method for impregnating porous bodies
Inventor: ROEDDER KARL-MARTIN DIPL CHEM
IPC: B05D7/22
Filed: 1982-12-11
Abstract: The present invention relates to a method for impregnating porous bodies which permits a uniform impregnation with a defined quantity of an impregnation solution. In the claimed method, the impregnation solution and the body to be impregnated are located in a container made of pliant material, preferably a plastic bag. The open end of the plastic bag is then connected to a vacuum installation, and a vacuum is applied inside the bag such that said bag lies closely against the body. A further embodiment consists in exerting such a pressure on the external wall of the plastic bag that the air within the bag escapes and the bag also rests closely against the body to be impregnated. A preferred embodiment of this mode of operation consists in dipping the plastic bag into water, in which case care must be taken that water does not penetrate into the bag. In this way, a uniform impregnation of the moulded bodies as far as the desired immersion depth is obtained. With this mode of operation, no losses in impregnation means occur and in the case of materials with fine pores a larger penetration depth can be achieved than with previously known impregnation methods.
