Patent DE-4139681-A1 (DE)
Title: Bass loudspeaker drive unit - uses diaphragm suspension of negligible stiffness and PID controller to compensate for diaphragm deflection
Inventor: CZERNY HERIBERT DIPL ING
IPC: H04R3/00
Filed: 1991-12-02
Abstract: The loudspeaker comprises a diaphragm, voice coil and magnet system. The centring mounting of the diaphragm has high compliance and the deflection of the diaphragm is compensated for using a process similar to that used in industrial line drawing recorders. The controlling low frequency represents the control input which is compared with a signal proportional to the diaphragm position, e.g. from a displacement pick-up (S1). A proportional-integral-differential (PID) controller receives the control input for driving the voice coil and diaphragm until the signal proportional to the diaphragm position momentarily corresponds to the controlling low frequency signal and the control deviation is fully compensated. ADVANTAGE - Avoids mass-spring resonance of diaphragm, linearity errors and creep effects.

Patent DE-4203878-A1 (DE)
Inventor: VOLZ PETER DR
IPC: B60T8/48
Filed: 1992-02-11
Abstract: Proposed is a slip-controlled brake system in which inlet-valve operation noise is damped effectively, but with a design which is less complex than that of prior art systems. The invention achieves this by virtue of the fact that a common differentially acting pressure-control device is fitted between an auxiliary pressure source (22) and the inlet valves (7, 8) of several wheel brakes. A reference pressure corresponding to the brake pressure at one of the wheels is fed to the pressure-control device (20) through a pressure selector (24). The pressure selector (24) may be designed so that it transmits either the highest or the lowest of the wheel brake pressures.

Patent DE-4208442-A1 (DE)
Inventor: BERZHEIM HANSBERND
IPC: B01F5/04
Filed: 1992-03-17
Abstract: In a suction/mixing device, a primary fluid flowing through a main channel (3) sucks a secondary fluid flowing through a secondary channel (5). The suction/mixing zone (11) has at its mouth a narrow cross-sectional shape and the cross-sectional surface at the mouth lies in the size range of the smallest effective cross-sectional surface in the primary fluid flow system. A laminar flow generating zone is arranged upstream of the mouth, in the direction of flow of the primary fluid, and the secondary channel is formed at the mouth by a plurality of uniformly distributed supply channels (7). High suction power and performance, as well as fine mixing and homogenizing, are thus obtained. Some of the most important domains of application are the domestic services technology, heating, laboratory, engine, cleaning, gardening and aquarium-building technologies.

Patent DE-4301052-A1 (DE)
Inventor: HUETTEMANN WILFRIED
IPC: A47L15/44
Filed: 1993-01-16
Abstract: In a dishwasher (2) or washing machine having a metering device (1, 1') for a liquid rinsing agent and a liquid or powdery cleaning agent, wherein each agent can be introduced separately into its own supply chamber (9) manually via an assigned filling aperture (6) of the meterer (3), at least the filling aperture (6) for the rinsing agent is provided with a filling guard (19). Said filling guard (19) prevents filling of the supply chamber of the rinsing agent meterer (3) with an unintended washing agent. The filling guard (19) can advantageously be combined with a filling aid (21; 22) which allows simple filling of the meterer, even when the appliance door (24) is partially opened. In a simple manner, the filling guard can be constructed as a strainer (20) which covers the filling aperture of the metering device and the filling aid can be constructed as a pivotable filling nozzle (22), the mesh width of the strainer (20) for the insert in the rinsing agent meterer (3) being designed in such a way that only liquid rinsing agent (13) is allowed through. As a result, interferences on the metering device and thus ensuing poor washing results are reliably avoided. <IMAGE>

Title: Cageless rolling-contact bearing
Inventor: BRANDENSTEIN MANFRED
IPC: F16C19/26
Filed: 1993-03-13
Abstract: A rolling-contact bearing without a cage but with a full set of rolling elements is provided with different track cross-sections in the loaded zone 4 and the unloaded zone 5 of the stationary race 1. In the unloaded zone 5, the rolling elements 3 roll on a smaller rolling radius R2 than in the loaded zone 4. As a result, they are accelerated as they enter the loaded zone 4 and in each case leave a smaller gap a with respect to the next. Wear is thus avoided. <IMAGE>

Title: Flexible packing material - has antistatic protection by attaching conducting tapes with perforated air-gaps, to reduce potential
Inventor: TREPTE PETER
IPC: B32B38/04
Filed: 1993-03-26
Abstract: Process is claimed to mfr. lining material, with an electrically insulated layer, from a fabric or foil, and having woven electrical conducting bands. When the insulated layer has been attached to the lining material, it is then perforated. The appts. is also claimed. Packing loose goods into flexible containers may involve dust, damp or gases to create an explosive situation. This is avoided by reducing the sheet or brush discharge from static build-up during the loading or unloading, caused by friction against the insulated surfaces. A woven flexible lining may have a waterproof layer of plastic foil attached to it. By weaving a conductive tape, and attaching this in a zig-zag manner across the fabric, the surface of potential static is reduced to an area which will not build up to a dangerous voltage level. To create a connection between the plastic foil (2) which is an electrically insulating layer, and the conductive tapes (3) attached to the woven lining material (6), the combined material is brought around an insulated roller (4) and a conductive roller (7) which is earthed. ADVANTAGE - The conducting bands reduce the area of surfaec subject to static, and hence reducing the potential. The perforations permit conductivity to the bands, to and from the interior. Explosion hazards are eliminated. The high tension perforating method is more economic than laser treatment.

Title: Rotary tubular furnace for refuse incineration
Inventor: WIEDERMANN WOLFGANG E
IPC: F23M5/00
Filed: 1993-07-14
Abstract: Rotary tubular furnaces for refuse incineration are generally installations which are operated at combustion temperatures of 700 DEG  to 900 DEG C. In this temperature range, particularly plastic components in the waste lead to undesired noxious gases and also to an unsatisfactory inerting of the cinders resulting during the combustion process. The novel rotary tubular furnace is intended to thermally treat the entire range of waste arising so that, on the one hand, a good inerting of the cinders resulting during the combustion is ensured and, on the other hand, the production of noxious waste gases is reduced to a minimum. The object under consideration is achieved in that the rotary tubular furnace is operated in the high-temperature range above 1200 DEG C, preferably at 1300 DEG C internal temperature, in that it has a horizontal position, in that the steel shell consists of corrosion-proof high-grade steel, in operation assumes a temperature of 300 to 400 DEG C and is enclosed by heat-insulating segments, at the outer surfaces of which a temperature of 40 DEG C to 50 DEG C is set. The rotary tubular furnace according to the invention is suitable for burning the entire range of waste arising in municipal as well as industrial sectors. <IMAGE>
