Title: Remotely controllable arrangement for adjusting the balance in the sound transmission part of an arrangement for reproducing a stereo sound event
Inventor: SCHROEDER WOLFGANG DIPL ING
IPC: H03G1/02
Filed: 1984-04-27
Abstract: In an arrangement for stereo reproduction of a sound event with an arrangement for automatic adjustment of the balance for the instantaneous listening location, a sound transmission part (2) of the arrangement contains a test sound source (12), which can be switched in a test sound operating mode into the sound channels (L, R) instead of the useful stereo sound source upstream of the signal inputs (9, 10) of the balance adjuster arrangement (8). The associated remote control transmitter (1) additionally contains a balance control arrangement (30) with a sound receiver arrangement (31) for receiving the test sounds at the listening location, a selection device (32) which forwards the received test sound signals to the two reception channels (36, 37) associated with the test sound signals and assigned to the sound channels of the sound transmission part, a measuring circuit (33) which generates output signals proportional to the volume at the listening location and a comparator arrangement (34) which, if the output signals on the reception channels are not identical, produces a corresponding adjustment command (BL or BR) to the adjustment inputs (15) of the balance adjuster arrangement. With an arrangement of this type, even an unskilled listener can at any time easily achieve perfect balance adjustment for a stereo transmission at his listening location. <IMAGE>

IPC: H01J61/35
Filed: 1984-09-05
Abstract: In the case of a compact low-pressure discharge lamp (1) having a discharge vessel (3) consisting of a plurality of parallel longitudinal-tube sections (6, 7) which are connected to one another, a cooling point (which determines the mercury-vapour pressure) of the discharge vessel (3) is arranged in the base (2), for vertical operation of the lamp (1) with the base (2) located at the bottom. The cooling point, which is formed by a bulge or a pin (19) in the discharge vessel (3), is located in the region of a cooling system having an air supply opening (20) as well as one or more exhaust-air openings (21) in the centre of the covering surface of the base (2). In addition, a device which forms an exhaust-air chimney is fitted above the base (2) in a space which is formed by the enveloping ends of all the longitudinal-tube sections (6, 7). The device preferably consists of a transluscent film (22) which closely encloses the outer walls of the longitudinal-tube sections (6, 7). This device increases the flow speed of the convection air in the cooling system and permits a maximum light yield from the lamp (1) as a result of the more effective cooling. <IMAGE>

Inventor: HAEUSER ERHARD
IPC: B29B7/28
Filed: 1985-06-27
Abstract: Casting resin components (4,5) coming together in a mixer (6) are dosed and circulated by means of pump structures (3). Each pump structure (3) has a dosing pump (17, 9) and a circulating pump (16, 10).

Title: Mounting shuttering for producing hexagonal or dodecahedral reinforced-concrete containers comprising prefabricated walls
Inventor: HIRSCH JOSEF DIPL ING
IPC: E04H17/26
Filed: 1985-09-16
Abstract: The invention relates to a mixed construction method for building reinforced-concrete containers comprising large-format prefabricated walls. When building water tanks, cesspits and liquid-manure pits, the high quality of the concrete, tightness of the joints and the economic removal of all loads are of great importance. A shuttering set comprises individual parts which can be screwed and have corresponding graduated portions, and permits the production of containers of different sizes. The configuration of the joints permits moments and transverse and longitudinal forces to be absorbed. The small joint width permits a very low degree of shrinkage and, at the same time, the required anchoring lengths of the reinforcement for force transmission are possible. The production concept, the configuration of the joints and the shaping of the containers permit crack-free structures and simplify production, mounting and static calculations.
