Patent DE-3327994-A1 (DE)
Title: Permanent-magnet dynamic loudspeaker with cylindrical radiation
Inventor: KREMER HELMUT
IPC: H04R1/40
Filed: 1983-07-25
Abstract: The underlying aim of this design was to build a loudspeaker incorporating every acoustic advantage which can easily be connected to all stereo systems. The acoustic short-circuits occurring in duo-cone loudspeakers are eliminated by means of the accelerators. The sound baffles prevent reflections on adjacent walls. The housing is ventilated with a transmission line. Emission of half-waves and housing reflections is prevented by foam-rubber sound-absorbers. No equaliser is required. The separate "Frequency divider for centring magnetostatic loudspeakers" could be considered for use as a frequency divider. The loudspeakers mounted in a vertical line ensure straight wave fronts. Different diaphragm widths produce a phase shift in the RF range in the case of listening angles of less than 45 degrees, i.e. the loudspeaker would have to be turned slightly towards the listener. This can be prevented by shifting the tweeter in the vicinity of the tweeter cone half which faces the listener, so that straight wave fronts are theoretically still radiated if the listener is positioned between the loudspeakers. The middle sound baffle would then have to be slightly movable. For high-power applications, the loudspeaker can be fitted with a fan. Through corresponding modification of the internal structure, a channel is obtained through which air can be blown in front of the loudspeakers, in order to ... Original abstract incomplete.
Patent DE-3331881-A1 (DE)
Title: Auxiliary drive mechanism
Inventor: LEUSCHNER GERHARD
IPC: B65B65/02
Filed: 1983-09-03
Abstract: The invention relates to an auxiliary drive mechanism for the transverse-sealing device on bag forming, filling and sealing machines for producing two different output speeds for adaptation of the welding-jaw speed to the packing-means path speed, the aim being to avoid deformation of the packing-means path during the transverse-sealing process by matching the speeds. This is achieved by the auxiliary drive mechanism being constructed as an infinitely adjustable two-speed multiple-disc chain drive with two output shafts for the drive shafts of the welding-jaw carriers, which output shafts are connected via transmission elements alternately transmitting force, an electromagnetic multiple-disc clutch being arranged on one output shaft and a grip-roller and expanding friction clutch being arranged on the second output shaft. The electromagnetic multiple-disc clutch can be operated via adjustable trip cams.
Patent DE-3339702-A1 (DE)
Title: Admixing nozzle for fire extinguishing purposes
Inventor: SCHWALM FRANZ
IPC: A62C5/02
Filed: 1983-11-03
Abstract: The admixing nozzle can be used by fire brigades when fighting fires either as an admixing nozzle, ie. for admixing an additive, or else as a normal nozzle without admixing. During the extinguishing operation, the suction of the water emerging from the mouthpiece 1) of the admixing nozzle acts via the intake tube 2), running in the admixing nozzle, to take in the additive which is in a tank 3) and mix it with the extinguishing water. The connection of the additive tank 3) to the intake tube is performed by pushing the additive tank into the guide cage 5) as far as the bottom plate 4). In so doing, the mouths of the intake tube 2) and of the aerating tube 6), which are located there, pierce the bottom of the additive tank 3). After emptying, the tank can be pulled out again and exchanged for a full tank. It is not necessary to interrupt the water flow. After removing the additive tank, the admixing nozzle can be used as a normal nozzle, as customary at present with fire brigades. <IMAGE>

Title: Process for producing bar-shaped machine components
IPC: C21D8/06
Filed: 1984-09-21
Abstract: Processes are indicated for producing bar-shaped machine components which can be highly stressed statically and/or dynamically, with stress concentration in their edge contours. Precipitation-hardened and/or fine grain-forming microalloyed steels are used as a material. From these steels, the bars are first hot-rolled, in particular in such a way that the rolling is completed in a temperature range from 800 DEG C to 1150 DEG C. If this is not possible, the bars are subjected to a special heat treatment after rolling and, starting for this from a temperature at which the microstructure is ferritic-perlitic, heated to a temperature between 800 DEG C and 1000 DEG C. In both cases, the bars are then further treated purposefully in such a way that they are cooled under control from a temperature within said ranges. The cooling is effected by a suitable cooling process at a cooling rate, which effects precipitation-hardening and/or fine grain formation and produces as complete as possible a ferritic-perlitic microstructure in the bar material, while avoiding a significant formation of bainite, to a temperature at least 50 DEG C below that at which the transformation into ferrite and perlite is complete. The bars are then cleaned on the outside by a special process and, at the same time, their edge zone is hardened. Subsequently, parts are severed from these bars and, on these bar parts, by cold-forming ... Original abstract incomplete.

Title: Device for the microfocal generation of mechanical vibrations of the low-frequency range, even in deeper layers of the body
Inventor: SCHUBERT WERNER DR MED
IPC: A61B17/92
Filed: 1984-10-27
Abstract: In the body, vibration also causes, at the least, separation at interfaces. Metered vibration is generally regarded as being beneficial to health. Elongate instruments, e.g. medical tubes, catheters, cannulas or needles, may be equipped at the front with the extremely small linear motor for generating vibrations or mechanical vibrations of the low-frequency range. It is then possible in a gentler way, including selectively in different foci, also to reach deep into the body for endotherapy, in order to use the linear motor, for example in the large bile duct, even in combination with a nozzle head and also by a fluid such as physiological saline solution, for vibration purposes in this duct even over a fairly long period of time in order to promote flow of bile or to expel stones. The linear motor with its piston and the device for the microfocal generation of mechanical vibrations of the low-frequency range can be used as a valve for the nozzles of a nozzle head, and, if the front part of the piston is appropriately designed, as a tool which can also be removed from the nozzle head from the proximal side for further medical purposes.

Title: Insulated piston
Inventor: WIESER RUDOLF DR
IPC: F02B3/06
Filed: 1984-11-07
Abstract: An insulated piston for high-speed vehicle diesel engines in a plurality of different embodiments is proposed, which combines a high insulation effect with low manufacturing cost. The new piston has only two main components, that is, a thick-walled insulation disc of quartz glass or high-strength ceramic or sintered materials (sintered metals) and a metal cylinder shaft. The thick-walled insulation disc with built-in combustion chamber is pressed or cast into a tapered end bore or recess of the cylinder shaft. In this way the insulation disc is prestressed against compressive stresses. The thick-walled insulation disc is supported in the cylinder shaft only in the tapered area of the former, thereby achieving definite conditions with regard to the support forces. It is possible to additionally reinforce both the cylinder head side half of the cylinder shaft, by means of a high-strength metal thrust ring and to additionally reinforce the thick-walled insulation disc by means of a peripheral flange ring and a tapered pretensioning ring. In this way an especially high safeguard against the fracture of the thick-walled insulation disc is achieved. The fuel saving due to the piston according to the invention will be approximately 10% in vehicle diesel engines. <IMAGE>
