Patent DE-3104105-A1 (DE)
Title: Rotary bond of formed sheet-metal parts
Inventor: LEISTRITZ HANS KARL DR
IPC: B23K20/12
Filed: 1981-02-06
Abstract: The patent application, designated as a rotary bond of formed sheet-metal parts, relates to a bonding technique, similar to the friction welding technique, for sheet-metal-formed adjoining parts on rotationally symmetric surfaces, and in fact in particular while utilising the elastic restoring forces of sheet-metal parts, which are applied before the start of rotation on the inside with simultaneous deformation of the sheet-metal parts or on the outside under applied pressure. The formed sheet-metal parts are brought to bear mainly against materials with a lower deformation resistance, that is, for example, steel sheet against aluminium diecasting or extruded aluminium parts. An insufficiency of surface unevenness and roughness peaks can be compensated for by additional shearing edges or point-like shearing peaks. Additional constrictions can be integrated by means of magnetic forming technique.

Title: Safety device on an internal combustion engine
Inventor: WOLF HORST
IPC: F01P11/14
Filed: 1981-07-11
Abstract: For protection against water hammer due to water leakage from the charge air cooler (13) of the internal combustion engine a safety device (11) is situated on the discharge aperture (12) of the water leakage collecting chamber. A seal comprising a valve ball (15) and compression spring (16) arranged in the housing (14) is held in the closed position by a moisture-sensitive element (17). As soon as the moisture-sensitive element (17) is permeated by the admission of cooling water from a leak, it loses its solid state and begins to dissolve. After just a short time, the compression spring (16) is then capable of displacing the valve ball (15) in the opening direction, thereby freeing the outlet aperture (19). When the water leakage collecting chamber is dry the safety device (11) is completely closed so that no charge air can escape unnecessarily and no unfiltered air can be drawn in during the starting process. <IMAGE>

Patent DE-3215094-A1 (DE)
Title: Peeling and debarking machine working in three dimensions
Inventor: ZSIDA ATTILA
IPC: B27L1/04
Filed: 1982-04-23
Abstract: This machine is required to peel and debark logs or branches which are neither straight nor have a curvature in one plane, but rather may curve in any direction in space. In this case, the workpiece is firmly held and the machine adjusts itself to any changes in shape, simultaneously peeling and debarking. So as not to remove too much from the diameter, the working tool, a peeling knife, is adjustable with respect to the surface of the wood and is mounted resiliently in a peeling head. This peeling head surrounds the workpiece, debarks and peels it with the peeling knife, and does so in any possible position of a predetermined workpiece having any desired shape.
Patent DE-3219144-A1 (DE)
Title: Electronic writing system
Inventor: WEBER LUDWIG
IPC: B41J5/46
Filed: 1982-05-21
Abstract: The invention relates to a fast input for electronic writing systems. The fast input exhibits a RAM memory with fast access in which frequently recurring words and phrases are stored. The storage locations are addressed by the initial letters of the words stored or by the characteristic letters of the phrases. In the conventional input of words into the main memory by means of the keyboard, the addresses of the RAM memory are interrogated in parallel. The address in each case addressed in the RAM memory can be called up via a retrieval key and its content can be read into the main memory. If the memory word called up does not correspond to the required word, it can be deleted again in the main memory. The interrogation cycle is reset after complete input of a word by operating the space bar or automatically at the end of the reading-in of a stored word. The interrogation cycle is restarted at the beginning of the input of the next word.
Patent DE-3219872-A1 (DE)
Title: Device for quiet storage of rod profiles, especially round rods and pipes, in a mobile collection trough
Inventor: AENGENEYNDT WOLF DIPL ING
IPC: B65G57/18
Filed: 1982-05-27
Abstract: Said mobile collection trough has trough sides and storage levers, which are inclined slightly downwards from the feed side towards the opposite trough wall. The trough wall opposite the feed side is inclined obliquely inwards and merges into a trough base with concave curvature. The free ends of the storage levers together with the trough wall facing them form a passage gap for the rod profiles. For loading, the collection trough can be moved into a transfer grating having grating sides parallel to the trough sides and moved out in stages during loading. The grating sides have outlet flanks and adjoining, steeply downward sloping slide flanks, which together with the facing trough wall form a wedge-shaped gap towards the trough depth and the trough width, which gap opens or widens as the collection trough moves out of the transfer grating during loading with successive clearance of the internal space of the trough. In this manner it is achieved that the rod profiles roll individually one after the other to the base of the collection trough and silently build up on one another to form a bundle without falling. <IMAGE>
