Patent DE-3417100-A1 (DE)
Title: Chain guide for a timing chain for driving a camshaft
Inventor: VOLLMER HERMANN DIPL ING
IPC: F16H7/06
Filed: 1984-05-09
Abstract: The invention relates to a chain guide for a simple timing chain for driving a camshaft on an internal combustion engine. To avoid longitudinal and transverse vibrations, the load-carrying strand running through the guiding blade is guided in a closed channel housing. The channel housing consists of a U-shaped basic housing, into which the timing chain is inserted, whereupon the opening is closed by means of a cover. To compensate for manufacturing tolerances of the crank case, it may be advantageous if the guiding blade and also, if required, the tensioning blade are mounted to float transversely to the longitudinal direction of the chain.

Title: Heat-absorbing filter made from glass for high thermal loading
Inventor: LUDWIG MANFRED DR
IPC: G02B5/20
Filed: 1984-05-28
Abstract: The invention relates to a heat-absorbing filter made from glass for high thermal loading. It is applied in conjunction with optical equipment, in particular in the case of projectors, in which the thermal radiation of a radiation source is filtered out by means of filters in order to protect the system against thermal and mechanical destruction. The filters are highly loaded thermally by the absorbing radiation. The limit of destruction is extended due to the fact that the filter is constructed as a curved parallel plate whose convex side faces the light source.
Patent DE-3430757-A1 (DE)
Inventor: SPEICH FRANCISCO
IPC: D04B23/22
Filed: 1984-08-21
Abstract: PCT No. PCT/CH85/00019 Sec. 371 Date Dec. 19, 1985 Sec. 102(e) Date Dec. 19, 1985 PCT Filed Feb. 6, 1985 PCT Pub. No. WO85/04911 PCT Pub. Date Nov. 7, 1985.In a warp knitting machine, warp stitch rows are formed from warp threads which are held together at least by a weft thread. Patterned threads are applied to the warp rows and are fed in a manner similar to the warp threads. For this purpose, a warp thread guide (18) and pattern thread guides (24) are positioned in front of the knitting needles and are moved over the knitting needles. At the sections of the knitting which are to receive a pattern, the pattern threads are applied on top of the warp threads resting in the needles and are knitted together. At the locations where no pattern is desired, controlled thread retainers prevent the insertion or threading of the pattern threads into the knitting needles and hence the knitting of the pattern threads in with the warp threads does not take place. At the pattern-free locations, the pattern threads are simply inserted into the warp stitch rows.

Title: Tensioning device for a ribbon-transporting device on typewriters or similar office machines
Inventor: FRERICHS KLAUS-DIETER ING GRAD
IPC: B41J33/52
Filed: 1984-12-01
Abstract: In order to guarantee secure and smooth transporting of the ink ribbon and/or correction ribbon in typewriters or similar office machines, a tensioning device is essential for keeping the ink ribbon and/or correction ribbon taut. For this purpose, a plurality of tensioning devices have already been disclosed which, however, are less suitable for automatic production and are complicated in construction. The invention is based on the object of providing a tensioning device for ribbon-transporting devices in typewriters or similar office machines, which device can be produced and assembled in a simple and inexpensive manner and is suitable for automatic production. This object is achieved in that a compression spring (27) is wrapped under prestress with frictional engagement on the one hand with one end (28) around a bearing journal (29) on a hub (30) bearing the supply spool (3) and, on the other hand, with the other end (31) around a bearing journal (32) arranged securely against rotation, in such a way that one end (28 or 31) of the compression spring (27) can be wound by the driven supply spool (3) in the drawing-off direction counter to its winding direction and, if the drive of the supply spool (3) is interrupted, exerts a restoring moment on the supply spool (3) to keep the ribbon taut. As a result, a tensioning device which can be produced and assembled easily is provided for ink ribbons or correction ribbons and allows automatic production. <IMAGE>

Patent DE-3507744-A1 (DE)
Title: Method for protecting databases and/or computer systems in electronic data processing and/or data technology against access by unauthorised persons
Inventor: NEUMANN KARL-JOACHIM
IPC: G06F21/31
Filed: 1985-03-05
Abstract: According to the method, direct access to a database and/or computer system is decoupled with respect to telecommunication by interposing a device (data switch and/or data transfer station). The data switch and/or data transfer station handles inputs and retrievals of data to and from the database and/or computer system by preferably mechanical (and automatic) means. Thus, unauthorised persons only have access to a data switch and/or data transfer station but never to data of the database and/or computer system itself. Interposition of the device delays the data transfer by a maximum of 1-2 minutes, but not the transmission rates.
