Title: Scrap removing mechanism from cardboard blank
IPC: B26D7/18
Filed: 1991-02-27
Abstract: The cardboard blank is stamped from a sheet of cardboard and contains unwanted cut-outs, which are removed in a second operation by a special tool (20) with a cross-section, which corresponds to the shape of the scrap material to be removed.  The blank (10) is supported on a table (14) with an opening aligned with the tool. A leaf spring (30) is mounted in the opening with its tip (32) aligned with the tool. The latter is pressed downwards and forces the scrap material out of the hole onto the spring tip. Further movement of the tool deflects the spring to form a chute for the scrap material discarding.

Patent DE-4112728-A1 (DE)
Inventor: FAHRION OTMAR
IPC: G07C9/00
Filed: 1991-04-18
Abstract: The alleyway-monitoring device disclosed has, mounted at different heights, two light barriers (16 to 26, 28 to 30), the higher of which is at a height at which the light beam can be broken only by fork-lift trucks.

Title: Time discriminator for scintillation detector - processes highly amplified photomultiplier signals on basis of low ohmic engagement for subsequent processing
Inventor: MUENNING HANS DIPL ING DR
IPC: G01T1/16
Filed: 1991-08-06
Abstract: One of the electrodes (1) of the photomultiplier (2) with adequate amplification, at which the constant fraction pulse form is used is sepd. from the voltage distributor chain (3) via a resistance (4) and the thus occurring voltage signal is fed to a discriminator (5) directly adjacent to the photomultipler.

Voltage supply (6) to the multiplier is such that the voltage distributor chain (3) is connected at a point to earth potential. The constant fraction electrode in the signal free state is at zero potential and thus the current changeover point which causes a voltage changeover point via the resistance is determined against earth reference. USE - Nuclear spectroscopy.

Filed: 1992-01-24
Abstract: Reactors for the anaerobic purification of waste water which operate by the UASB process (Upflow Anaerobic Sludge Blanket) have at the top separating modules for separating the three phases resulting from the purification: a plurality of immersed collecting hoods (14), which are arranged in a stack, for the biogas, extractors, which are located above the water level, for waste air, and a discharge, which is located under the water level, for the purified waste water. The innovation in these modules is the fact that all the walls, covers and inbuilt components (13-15) of the module consist of plastic reinforced with steel profiles, and that all the discharge lines (17, 18, 19) open out of a narrow side of the module and are connected to channels (8) which are located outside the modules and can be closed in sections. The novel design makes it possible for each module to be removed and undergo maintenance without interrupting operation.
