Title: Destruction of microorganisms in gaseous, liq. or pasty medium
Inventor: ROINER FRANZ PROF
IPC: A23C3/07
Filed: 1992-03-05
Abstract: Microorganisms are destroyed in a gaseous, liq. and/or pasty medium by treating the medium with ultrasound.     Pref. treatment is for not above 60 secs., at a frequency of not less than 18 kHz (not less than 20 kHz), a capacity of not less than 2000 watts, and a constant or variable temp. of 0-100 deg.C., opt. using an agitated medium. Treatment may be first at a raised temp. and then at a reduced temp., or vice versa, e.g. it may be raised from a starting temp. of not below 58 deg.C. or lowered from a starting temp. of not above 15 deg.C. and may be altered stepwise. Ultrasound treatment may be repeated, and before repitition the temp. of the medium is brought to the initial value. The viscosity of the medium may be reduced. The pH is not 7, pref. below 6.8 or above 7.1. Before, during or after the ultrasound treatment, the medium may be irradiated with micro-waves. The ultrasound intensity may be varied, and is pref. raised during treatment. The intensity is varied in pulses and/or is briefly interrupted, and is pref. accompanised by micro-wave treatment for not above 3 secs.. Several ultrasound sources may be used, in sequence and/or in parallel, with differing capacities, and vertical and/or transverse and/or sloping w.r.t. the medium. The intensity of treatment is controlled by the distance of the ultrasound source from the medium, by contact of the source with medium and/or by the depth of dipping of the source into the medium. In flowing gaseous media, the amt. of dry matter and/or moisture is varied. The temp., pH value, viscosity, dry matter content, moisture content, flow rate and/or degree of agitation of the medium may be varied during, before or after the ultrasound treatment. Coarse and/or fine dispersed substances may be fed into the ultrasound treatment space and/or form additionally in the substrate to be treated, thus accelerating the destruction of microoganisms present and/or the homogenisation. The density of the medium is at least 1.01 g/cc, and its acitivity or water activity is not above 0.995.

Title: Vibration generator with two parallel cut-of-balance shafts - has unit to vary direction of resultant out-of-balance force
Inventor: BLAUENSTEINER KARL DIPL ING
IPC: B06B1/16
Filed: 1992-06-10
Abstract: A vibration generation machine has two parallel shafts (W1, W2) each of which is provided with an out-of-balance weight (U1, U2). The shafts rotate at the same speed but in opposite directions and their speeds are synchronised by a double-sided toothed belt (DZ) which passes around guide pulleys (SU1, SU2, SU3) with the pulleys (SU1, SU2) being positionally adjustable. The facility to adjust the positions of the guide pulleys (SU1, SU2) changes the angular position of the balance weight on one shaft relative to the angular position of the balance weight of the other shaft which enables the direction of the resultant out-of-balance force to be varied. The machine is used to drive a vibration conveyor and the change in direction of the out-of-balance force enables the speed of the conveyor to be adjusted whilst it is operating. USE/ADVANTAGE - Vibration generator with variable direction of out-of-balance force.

Title: Exchangeable friction pins
Inventor: HAMANN RAINER
IPC: A61C5/08
Filed: 1993-04-22
Abstract: In dentistry, telescopic crowns are usually produced with parallel walls or conically. These shapes result in cosmetic drawbacks of both systems. In the present novel system, friction is achieved by exchangeable friction pins. The primary member is prepared by producing a uniform cap and by designing two parallel surfaces lying opposite each other in the approximal region. Further operations are unnecessary. The secondary member is produced by applying wire profiles on to the prepared friction surfaces of the primary member as spacers and by surrounding them with wax. The openings obtained after casting and fitting are widened. A plastic profile can then be inserted to ensure the desired soft friction. The novel system has the following advantages:   - little time expenditure for production of primary and secondary members;   -production of secondary member and model cast base in one piece; -satisfactory cosmetic appearance because there are only few shape requirements; -secure hold which can be restored, if required, by exchanging the friction pin;   -if desired, can also be produced with a snap-on effect.   <IMAGE>
