Title: Interferometer for detecting electric field generated vibration of metallic particles in gas insulated HV switchgear - feeds laser beam into sensing and reference optical fibre branches of Mach=Zehnder interferometer, has two photodetectors at output of combiner-divider and control loop for zeroing difference between detector voltages
Inventor: BOHNERT KLAUS DR
IPC: G01V1/00
Filed: 1992-07-27
Abstract: The interferometer detects vibrations in the gas-insulated HV switchgear enclosure (3) caused by loose metallic particles moving in the alternate magnetic field in the equipment. Two branches (1, 2), of a fibre-optic Mach-Zehnder interferometer are driven by laser (4) and splitter (5). One fibre branch (1) is attached to a point of peak vibration on (3). The two branches (1, 2) are connected to via a combiner (6) to detectors (7). A control loop (8) is formed whereby a piezo-electric phase modulator (9) and a signal analyser (10) regulate the operating point of the system. Length variations in branch (1) cause a beat signal to be generated with branch (2) corresponding to the detected vibrations. ADVANTAGE - Wide bandwidth (several tens of MHz) of measurement, high sensitivity and immunity to electromagnetic interference.

Title: Bulk-material transshipment system
Inventor: GRATHOFF HARTMUT DIPL ING
IPC: B65G67/60
Filed: 1993-02-06
Abstract: The invention relates to a bulk-material transshipment system for ocean-going ships having movably arranged bulk-material transshipment appliances (23). Instead of a pier or a quay installation, or a land-side depot equipped with fork-lift trucks and reclaiming appliances and the conveyor installations necessary for this purpose, a trough-shaped bulk-material store (14), on the side walls (15) of which rails (22) are laid, is arranged on the ocean floor (3) at a water depth safely navigable by ocean-going ships. Transshipment appliances (23) move on these rails and convey out of ships (28) into the trough-shaped store (14) or onto a conveyor-belt system (25) leading directly from the store to a bulk-material processing plant (for example, a coal-fired power station). The same transshipment appliances (23) can also convey from the trough-shaped bulk-material store (14) onto the conveyor system (25) or into ships (28). <IMAGE>

Inventor: BUSCHEK HERBERT DIPL CHEM ING
IPC: B01L3/00
Filed: 1993-02-13
Abstract: System for preparing liquids from at least one solid and from at least one liquid phase. The system comprises a vessel in which the solid or solids are situated and a dry chamber which is connected to the vessel or can be connected to the vessel. The dry chamber is separated from the vessel interior by a separating means which is permeable to water vapour but is impermeable to liquids. The system is suitable for the production of liquids from moisture-sensitive solids. These solids can be stored in the vessel, since the atmospheric humidity in the interior is decreased by the desiccant. The liquid can be prepared in one and the same vessel by addition of a liquid phase, since the desiccant is separated off from the vessel interior. <IMAGE>

Title: Apparatus for the manual folding of notepaper and enclosures
Inventor: SICHERT HARALD DIPL ING
IPC: B43M3/02
Filed: 1993-02-25
Abstract: The grant of a patent is applied for in respect of the invention of an apparatus for the manual folding of notepaper, so that the latter, after the folding operation, can be introduced into a window envelope in a manner such that the address field becomes fully visible. The manual methods used hitherto are unsatisfactory. Mechanical methods are economically impracticable for small quantities. The invention allows correct, rapid, reproducible and economical folding of notepaper and annexes thereto for small quantities. The sheet of notepaper to be folded is introduced into the apparatus the wrong way round, with the address field for the recipient facing downwards. The folding flap is closed and the projecting ends of the sheet of notepaper are successively folded over the folding flap to the fold marks. The folded sheet of notepaper is then removed and can be introduced into a DIN long (110x220 mm) window envelope, so that the field for the address of the recipient appears completely in the window. This method can be used analogously for the manual folding of a plurality of sheets of notepaper or for notepaper and enclosure.

Title: Transducer for condensor microphones having a variable directional pattern
Inventor: HIBBING MANFRED DIPL PHYS
IPC: H04R1/38
Filed: 1993-03-12
Abstract: The invention is directed towards a dual transducer for condensor microphones having a variable directional pattern. These microphones consist of a symmetric arrangement of two transducers having cardioid directional patterns pointing in opposite direction. The transducers are enclosed by a housing connecting them. To provide for a compact mechanical structure and to obtain cardioid directional patterns within a wide frequency range, it is proposed to arrange both wide and narrow acoustic passages in an axial and radially symmetric arrangement in the housing. The total acoustic impedance of these passages has a constant characteristic at low frequencies and one that rises, towards high frequencies. A cardioid directional pattern is obtained even at low frequencies.

Title: Cooling apparatus
Inventor: LUETHIN MARTIN
IPC: B65B63/08
Filed: 1993-04-14
Abstract: The cooling apparatus, which is intended for thermoplastic packaging material and packs, preferably blister packs produced from it, has cooling plates (16) which are loaded by cold water. Arranged in the cooling apparatus are two regulating devices (13, 14) which influence the cooling-water temperature in the cooling plates and of which one (13) is effective during normal operation and has a desired-value input (39). The working cooling temperature is set at this desired-value input. The other (14) of the two regulating devices is effective in the event of an interruption in operation and likewise has a desired-value input (43). A higher temperature than the working cooling temperature is set at this desired-value input. This prevents the cooling plates from steaming up or "sweating" as a result of moisture from the ambient air in the event of an interruption in operation. <IMAGE>

Title: Wall and ceiling cladding for firing ranges
Inventor: RUDAT HANS-DIETER
IPC: F41J1/10
Filed: 1993-06-08
Abstract: The wall and ceiling cladding for firing ranges is formed in that acoustic panels are fitted at a distance in front of the wall or ceiling which is to be clad, and in that the surface of the acoustic panels which is directed away from the wall or ceiling is covered by a close-meshed facing fabric consisting of a barely inflammable material. The acoustic panels consist of a non-inflammable or barely inflammable sound-insulating material which is free of matter which is hazardous to the health. A load-bearing frame is preferably mounted on the wall or ceiling which is to be clad, and the acoustic panels are fastened on the load-bearing frame, with the result that the thickness of the load-bearing frame determines the distance of the acoustic panels from the wall or the ceiling. The wall and ceiling cladding formed in this manner can be mounted in a simple, rapid and cost-effective manner. It is easy to clean, gives a high degree of safety and exhibits good sound absorption and sound insulation. <IMAGE>
