Patent DE-4141675-A1 (DE)
Title: Flashlamp operation circuit performing continuous on=off switching - utilises semiconductor switch with photodiode in control circuit monitoring limiting current during discharge of capacitor
Inventor: DUENISCH INGO DIPL PHYS
IPC: G03B7/16
Filed: 1991-12-17
Abstract: The lamp (5a) is wired in series with an inductor (7) whose stored energy is dissipated in the form of current through a free-wheel diode (8) in parallel with the combination (5a,7). A semiconductor switch (6) is opened on attainment of a limiting current (about 150 A). On reclosure, further triggering (4) of the lamp (5a) is unnecessary because of sufficent residual ionisation. The cycle is continued until the capacitor (2) is discharged. USE/ADVANTAGE - With photographic camera. Short arc lamp having electrodes less than 1 cm apart can be used about 3000 times, dissipating 10 to 20 J per flash.
Patent DE-4200855-A1 (DE)
Title: Protective ground matting - is sewn together with adhesive-treated thread
Inventor: STOEVER HERMANN
IPC: B32B7/09
Filed: 1992-01-15
Abstract: The protective cover for ground, using a carrier of organic material, is stiched together with a thread which has previously been treated with an adhesive. Pref. before the thread is used, it is drawn through an adhesive and the surplus is scraped clear. The adhesive is carried on a roller immersed in an adhesive bath, to coat the thread. After the thread has been laid on the roller, it passes through a scraper to remove surplus adhesive. The thread is temporarily detached from the roller when it is engaged by the sewing needle. The adhesive roller covers with width of the matting, as does the adhesive container. USE/ADVANTAGE - The cover material is for laying on flat or angled ground surfaces as an erosion protection and/or mulching matting which can be provided with embedded seeds or used to prevent weed growth. The adhesive-treated thread gives the required adhesion within the matting without an adhesive application and attendant soling.

Title: Vairable length thermoplastic extrusion continuous prodn. with single mould - by introducing from heated nozzle in cooled tube contg. partition moved by material flow, and cooling on mould external wall
Inventor: BECK ERICH
IPC: B29C48/03
Filed: 1992-02-05
Abstract: The prodn. comprises intrusion and inserting a partition into the melt between the extruder and the mould to move the partition with the melt flow; and the intrusion in front of the partition is released from the mould and ejected by the pressure of the intrusion pressure of the next shot, the product is cooled further outside the mould. The melt is pref. discharged from the extruder through the heated nozzle into the cooled mould to solidify on the mould wall. As more extruded melt advances it builds up. A partition is inserted into the tool bore and moves forwards with the melt. As a result the pressure increases on the cooled material which is moved along accordingly. Continuing melt flow pref. presses the earlier material through the cooling stage. The tool to insert the partitions has two holes to feed fresh partitions in from a magazine. The length of prod. is controlled by processing time at a constant rate of extrusion, or, pref. by sensing magnetically the movement of the partition. ADVANTAGE - The prodn. uses only one single mould. The extrusion procedure is uninterrupted. The filling pressure may be adjusted.
