Title: Mixing liq. and/or solids with second liq. - using pumped second liq. to induce turbulent mixing
Inventor: MOELLER WERNER PROF DR ING
IPC: B01F5/02
Filed: 1992-01-14
Abstract: In the mixing of a first liq. (e.g. feed liq.) and/or dispersed solids (e.g. solidified) with a second liq. (e.g. water or liq. mixt.) in a mixing tank, turbulent mixing is induced in the first liq. and/or dispersed solids in the tank by introducing the pumped second liq. in the form of one or more jets directed from one or more pipe openings onto one or more surfaces (pref. a free floating impact plate) in the tank interior. Also claimed are (i) use of a stream, which is directed from a pipe onto an impact plate, for mixing of different liqs. or of liqs. with disperse solids; and (ii) appts. for carrying out the mixing process. USE/ADVANTAGE - The process is used in the chemical pharamceutical and food industries for mixing components to cause chemical reaction, to produce a certain taste or to obtain a predetermined viscosity. Increased homogeniety of the mixt. is obtained without special mixing equipment and energy costs.
Patent DE-4201868-A1 (DE)
Inventor: KUMMERMEHR HANS
IPC: D06M101/02
Filed: 1992-01-24
Abstract: In order to be able to consolidate mineral fibers without binder, such as in particular glass wool, into a needle-felt by needle-punching, an agent as a needling aid which comprises a thixotropizing additive having a relatively low flow viscosity during needling and thus allows to effectively support the needling process, is added to the mineral fibers. At rest, this thixotropizing additive however has an extremely high viscosity, whereby the needle-punched felt obtains good strength. In particular for needling rock wool, suppler textile fibers are moreover added which contribute to improved mutual interlocking of the fibers, in particular in the case of mineral fibers such as basalt fibers, which can only with difficulty be interlocked by needling. A corresponding processing aid furthermore proves advantages in the production of a crimped mat from a laminar mat, as the drastically weakened resistance against further shifting makes it possible to reorient the fibers in the crimping zone, gently and to a large degree, without the application of excessively large forces.

Patent DE-4210710-A1 (DE)
Inventor: LENZ SIEGHART DIPL ING
IPC: B23F23/12
Filed: 1992-03-27
Abstract: The invention concerns a method and device for simultaneously working different parts of the surface of one and the same workpiece using two abrasive wheels. The method calls first for the smooth-polishing positions of the two abrasive wheels (4.1; 4.2) to be calculated. When the two abrasive wheels (4.1; 4.2) have been brought into these positions, the abrasive wheels (4.1; 4.2) are shaped with a dressing tool (1), thus producing the surface roughness appropriate for rough-grinding. Subsequently, the abrasive wheels (4.1; 4.2) are brought into the calculated rough-grinding positions and the rough-grinding carried out. The abrasive wheels (4.1; 4.2) are then brought into the smooth-polishing positions. In the following dressing procedure, the surface roughness appropriate for smooth-polishing is produced. The smooth-polishing is then carried out. In the device proposed, the abrasive-wheel carriages (14.1; 14.2) are disposed such that the two abrasive wheels (4.1; 4.2) have a common axis of rotation (15). A rotating dressing tool (1) mounted on a device (16) which can move in two dimensions is disposed parallel to this axis (15). The dressing tool (1) can be used to shape all the parts of the abrasive-wheel surface. The surface thus produced is reproduced accurately on the workpiece (2).

Title: Watch-dog system to protect against theft and break-ins
Inventor: WOLF OSKAR
IPC: B60R25/104
Filed: 1993-02-27
Abstract: Each time doors or windows are opened and each time an inclination switch is deflected when the car is tilted etc., a short pulse is generated (power switched on or off). The said short pulse is converted in the inaccessible watch dog safe into a continuous pulse which cannot be switched off unless the safe is opened. Conversion is made in this safe to the system's own battery if necessary and the audio and radio transmitters situated in it start to operate. The safe can only be unscrewed in accordance with a connection diagram using left-handed and right-handed screw threads in a sequence which is only known to the owner. The safe has a hollow tube which acts as a standing foot and through which the wires can be laid beneath the car, to improve the audio effect, a hole in the fuel pipe even being produced. <IMAGE>
