Patent DE-3238034-A1 (DE)
Title: Servomechanical power-amplification device for hand tools
Inventor: KAYSER-HEROLD UWE DIPL ING
IPC: B44B11/00
Filed: 1982-10-14
Abstract: With the servomechanical power-amplification device for hand tools, the hand power required in the use of a hand tool, e.g. sheet metal shears, is reduced by any constructionally selectable factor desired, without thereby altering the fundamental properties of the hand tool. The manual control of power and movement of the tool lever is possible just as well as with the original hand tool. According to the invention, the servomechanism is characterised by a motor-driven coupling shaft whose friction moment produced by a hand lever acts on a cable drum mounted in the tool lever. The friction moment proportional to the hand power on the coupling lever is converted by the cable drum into a cable pulling power proportional to the hand power. The cable connected to the opposite tool lever pulls the two tool levers together in the same direction as the hand power.

Title: Process and device for covering cylindrical bodies, such as rolled bales of agricultural harvested crops
Inventor: MOOSBRUCKER KARL
IPC: A01F15/07
Filed: 1983-03-28
Abstract: A process and a device are proposed which serve to cover cylindrical bales (1) prepared by a rolling process, especially of agricultural cereals, with a plurality of strip-shaped webs (2) immediately after rolling in such a manner that the cylindrical rolled bales (1) are continuously covered both at the lateral surface as well as at the end surfaces. The webs can be disposed parallel or inclined to the main axis of the bale. The webs are unwound from a roll (13) which is mounted on a pivotable carrying arm (9a, 9b). This carrying arm (9a, 9b) can be moved in such a manner that the roll (13) is guided along the end sides and along the lateral surface of the bale. In the process the bale can be stationary during covering with a web and then be shifted further in steps, or it can rotate uniformly in such a manner that during covering with a web its circumference rotates further by about half the web width. <IMAGE>

Title: Revolver cartridge with gas-sealing sleeve
Inventor: BORK NORBERT
IPC: F41A3/76
Filed: 1983-10-06
Abstract: In order to prevent the gas loss, according to the length of the barrel, completely or partially, a gas-sealing sleeve is inserted into the revolver cartridge described here and surrounds the powder inside the cartridge case. The projectile inserted into the cartridge case is located on the top side of the gas-sealing sleeve. After the ignition of the cartridge, the gas-sealing sleeve, together with the projectile, is driven out of the cartridge case by the powder gases and moved through the barrel. During its forward movement, the elastic gas-sealing sleeve closes the drum gap in a gas-tight manner according to the length of said gas-sealing sleeve (Figures A and B). After leaving the barrel muzzle, the gas-sealing sleeve falls down. Figures C and D: gas-sealing sleeve, the front side of which is burst open after the ignition of the cartridge, so that the projectile moves through the barrel faster than the gas-sealing sleeve. The drum gap is consequently closed for a longer time. Additional constructional features:   a Gas-sealing sleeve extendible by means of annularly arranged folds.   b Braking faces which can be spread by the gas-sealing sleeve after it leaves the muzzle.   These constructional elements are to be combined according to the intended purpose. <IMAGE>

Title: Photographic roller copier
Inventor: ZAHN WOLFGANG DR
IPC: G03B27/32
Filed: 1984-04-04
Abstract: The invention proceeds from a photographic roller copier for projecting originals of different side length onto a belt-shaped copying material whose belt width corresponds to a desired copying dimension. In this case, the originals have different formats, of which one is arranged in the longitudinal belt direction and the other transverse thereto. In order to be able to copy both types of original to the same size, two projection systems having a different image scale facilitating a uniform copy size of the two original formats can be mutually exchanged in the projection beam path. One system for the one type of original contains a rotating prism, in particular a pair of Porro prisms, for an image rotation by 90 DEG . Two projector gates which are mutually offset in the running direction of the belt are provided in an original stage in accordance with the different original formats, the offset of said gates corresponding precisely to the offset of the beam path through the rotating prism. <IMAGE>

Title: Device for the automatic feeding of single sheets from a magazine to the platen of an office machine
Inventor: STEINHILBER HELMUT
IPC: B41J13/00
Filed: 1984-05-04
Abstract: In a device for the automatic feeding of single sheets from a magazine to the platen of an office machine, the device is driven by the platen via a gear mechanism. For the case of the drive motor of the platen being too weak for the drive of the device, an electric auxiliary motor is provided which, in terms of drive, engages in the gear mechanism in the same direction as the platen and assists the platen in driving the device. The auxiliary motor is permanently electrified, but is too weak to drive the device alone. The auxiliary motor does not therefore impair the control of the device via the platen. On reversing the direction of rotation of the platen, the direction of rotation of the auxiliary motor is also reversed by means of a direction-of-rotation detector.
