Title: Curtain hanging device
Inventor: CICHON JOSEF
IPC: A47H7/02
Filed: 1981-06-06
Abstract: The curtain rail can be moved vertically up and down, actuated from the ground, together with the curtains. A vertical attachment strip, which has guide slots, is attached to the wall on each side of the window opening. A support arm is attached in each case to two displacement strips and the curtain rail is attached to said support arm. Each displacement strip is guided along the associated attachment strip, the engagement bolts mounted on the displacement strips being guided in the guide slots. The extensions of the engagement bolts, namely the grip bolts, each hang on a hook, which hooks are connected via a first cord or a second cord to a cord drum which is mounted on the wall in the lower region of the window. By actuating the cord drum, the displacement strips can be pulled upwards where the engagement bolts come to rest in the upper engagement slots. When the cord drum is actuated again, the engagement bolts are lifted out of the upper engagement position and the displacement strips can be lowered until the support rollers, mounted at the bottom of the displacement strips, stand on the floor and thus fix the lower end position.

Title: Pendulous tool on excavators, wheeled loaders, tractors and the like
Inventor: HILDEBRANDT GEB SEWERIN
IPC: E02F3/413
Filed: 1981-10-26
Abstract: On a pendulous tool on excavators, wheeled loaders, tractors and the like, with a pendulum brake which is fastened to a tool attachment and a tool bell, mounted in a bearing yoke of the tool attachment by a bearing pin and supporting in turn by means of a further bearing pin the tool or a rotary motor placed in front of the tool, and which consists of a brake caliper and a brake disc, the object is to relieve the bearing pin passing concentrically through the brake disc. This object is achieved by the invention in that a mounting is attached to the tool attachment, which mounting forks downwards into two receptacles for one brake caliper each, which, as viewed from the bearing pin, enclose an angle of more than 60 DEG  in the tool attachment, and in that the brake disc has an eccentric recess through which the bearing pin reaches into the tool bell. In this way, the brake disc is held in place at its periphery by two brake calipers so that the braking action on the brake disc is considerably increased.

Title: Device for obtaining wind energy
Inventor: HOEFGEN GUENTER DR
IPC: F03D9/12
Filed: 1982-03-15
Abstract: In the case of the device for obtaining wind energy a sail (2) is connected by way of hauling cables (9, 11) to a ground station (10) in which mechanical energy is converted into electrical energy. During a working cycle the sail is so aligned that a wind flow can exert the optimum effect on the sail, whereas during a recovery cycle on the other hand it is so aligned that the wind action is minimal. The position of the sail is controlled by varying the lengths of the hauling cables relative to one another. <IMAGE>
Patent DE-3211054-A1 (DE)
Title: Ring-sealed pipe plug connection
Inventor: WOLF FRANZ JOSEF
IPC: F16L17/025
Filed: 1982-03-25
Abstract: The invention relates to a ring-sealed pipe plug connection which is especially suitable for a pipe collar and a tip end. Large manufacturing tolerances occur particularly in the case of pipes of large diameter which are produced from mineral materials. Despite these manufacturing tolerances, the pipes, for example a pipe collar and a tip end, must be able to be reliably sealed. To this end, it is also necessary for the actual sealing insert to be mounted securely in the pipe collar. To this end, a pipe plug connection has a retaining ring, which is integrally formed on the sealing insert, with a contact device which is provided radially outwards thereon against the inner wall of the pipe collar. Furthermore, an approximately axially running wall element is provided on the retaining ring at a radial distance from the inner wall of the pipe collar. In addition to the wall element, the sealing insert has at least one sealing ring which provides a seal against the pushed-in tip end. Once the sealing insert has been inserted into the pipe collar, a sealing chamber which is formed between its inner wall to the retaining ring and to the wall element is filled with a hard sealing compound. The sleeve collar is in this case designed such that the sealing insert is inserted into an expanded collar fold until the retaining ring rests against the bottom of the fold. In order to compensate for manufacturing tolerances, the maximum external diameter of the retaining ring is dimensioned such that it is less than the minimum internal diameter of the axially extending fold limb. The compensation for tolerances is primarily achieved by centring elements which are integrally formed radially outwards on the retaining ring.
