Title: Portable power supply apparatus for mine workings
Inventor: GERASCH MANFRED
IPC: H02J7/34
Filed: 1984-03-23
Abstract: A portable power supply apparatus for mine workings and other regions where there is a risk of explosions combines the advantages of stationary power supply apparatuses and conventional portable intrinsically-safe accumulators for the power supply of measurement and analysis apparatuses. An electrical circuit arrangement (3) which is installed in the housing (1) of the accumulator has input connections (12, 13) for a rectified supply voltage, which is derived from a network or power supply. The circuit arrangement has at least two outputs (14, 15) of which a first (14) connects a predetermined limited voltage to the accumulator (2) as a charging voltage in the case of a current whose maximum is limited, and a second (15) supplies a supply voltage for the electrical apparatus (20), which supply voltage is reduced in comparison with the charging voltage, via a reduction circuit (16). At least one output (19, 19') of the accumulator (2) can be connected to an output (15, 22) of the power supply apparatus in parallel with the second output (15, 22) of the circuit arrangement (3), for the power supply of the electrical apparatus (20). <IMAGE>
Patent DE-3413810-A1 (DE)
Inventor: ARABIAN SANDRO
IPC: A61L9/14
Filed: 1984-04-12
Abstract: The room spray dispenser (1) holds a container (29) that is provided with a valve element (27) which also works simultaneously as a pump. Above the valve element (27) the operating end (25') of a pressure lever (25) is located. It is loaded in the direction of the valve element (27) with at least one spring (26,33). The blocking lever (14) has a raised contact surface (14''). This surface is pressed downward with the operating end (3') of a swivelling lever triggering mechanism, which is mounted on the door (5) or the door frame (6). This downward movement trips the blocking lever (14), which then allows the pressure lever (25) to press down upon the upper part of the valve element (27) due to the force of the tension spring (26). By the return movement of the swivelling lever (3) the blocking lever (14) is raised upwards to its original position and cocked by means of the cocking lever (15). The tension spring (26) is also stretched during this process. The advantage of this arrangement lies in its simple construction, positive operation, uniform dispensing of the mixture of deodorizing and/or scented liquid and air, and its general applicability to various kinds of door constructions or other elements which move relatively to each other. This arrangement requires no spray cans with propellent gas.

Title: Extruder head which can be swung open
Inventor: GERLOFF KLAUS DIPL ING
IPC: B29C48/07
Filed: 1984-05-19
Abstract: The die head on extruders for thermoplastic and thermosetting compositions is designed to be capable of opening in various ways in order to make the inner flow channels leading to the die ring with the extruder die more accessible for cleaning purposes. The opening mechanism of such so-called hinged die heads must be able to receive the comparatively high melt pressures without destruction and also without impermissible deformations, always leading to very robustly dimensioned designs with the disadvantages of high weights, high production costs and restricted accessibility. The invention avoids the strength requirements by supporting the pivotable die head parts against the fixed head by means of elastically resilient spring elements, preferably in the form of pressure medium cylinders.

Title: Shell-shaped loudspeaker box and a method for its production
Inventor: REUVER PIET DE
IPC: H04R1/34
Filed: 1984-08-03
Abstract: A loudspeaker box is constructed in the manner of a human larynx. The loudspeaker is suspended on the top of a spherical housing in a wooden ring, and the sound well of the loudspeaker is located approximately at the focus point of a hollow ellipsoid which produces the sound emission from the loudspeaker. The loudspeaker box has a rather high intrinsic weight with a small volume, to be precise in that the wall of the shell-shaped loudspeaker box is constructed from a hardened concrete mortar. The inside of the spherical loudspeaker housing is in this case provided during construction with a wall or is assembled from wall parts on which so-called "small concrete worms" are located. The latter are produced by forcing the concrete mortar through a meshed wire gauze and allowing these "small concrete worms" to harden. The effect of such "small concrete worms", consisting of a material which has a high intrinsic weight and furthermore remains porous in the dried state and has sound-absorbent properties to a high extent, is excellent in a shell-shaped loudspeaker box and, with the sound-reflector shell in the form of an ellipsoid, provides the startling effect that the entire frequency range of high, medium and low sound types is precisely reproduced using a very small loudspeaker box.

Patent DE-3515617-A1 (DE)
Inventor: SCHAAF HEINZ-JOSEF
IPC: A23P30/34
Filed: 1985-04-30
Abstract: The extrusion of food products is carried out at a pressure lower than the atmospheric pressure, thereby enabling to reduce the temperature of the dough to be extruded. It becomes thus possible to extrude materials and let them expand, materials which could not otherwise be used, either because of their heat sensitivity or because of their thermoplastic properties. Simultaneously, vapors coming out of the extruder may be condensated, thereby enabling to recover volatile aromas, and to thus increase the productivity of the process while preventing unpleasant smells from spreading throughout the production locals.
