Patent DE-3808088-A1 (DE)
Title: Process for separating off heavy metal ions from industrial waste waters
Inventor: BAUMBACH ERNST-AUGUST DR
IPC: C02F9/00
Filed: 1988-03-11
Abstract: In order to keep, in particular, the contents of cadmium, zinc and lead as low as possible in industrial waste waters (effluents), hydroxides of aluminium, iron and/or chromium are added to them in at least a ten-fold amount, based on the total of the number of moles of heavy metal ions, at pHs of 7.5 to 8.0. After 1 to 30 hours, the hydroxides are filtered off and Cd values < 0.04 mg/l, Zn values < 0.07 mg/l and lead values < 0.4 mg/l are obtained.

Title: Gum-massaging brush and toothbrush with protective covering
Inventor: KLASEN ANTON
IPC: A61C17/26
Filed: 1988-04-14
Abstract: The present device comprises a handle with in-built motor and the switching functions on/off, right-left, slow-fast. The motor has the task of driving a round brush via a shaft. This round brush is covered both over the rotating shaft and over one half of the brush. As a result of this, a rotating brush can now be used both to clean the teeth and to massage the gums. This presents considerable advantages over conventional toothbrushes (electrical or manual). The massaging and perfusion of the gums are improved. The brushing direction "red-white" is easier to maintain. The gums are healthier, and attachment of the teeth is improved. The expenditure of time and money is reduced and the success is better. At present, there is no alternative to this type of tooth and gum care.

Title: Aerostatic bearing with a split bearing shell
Inventor: TITTIZER GABRIEL
IPC: F16C32/06
Filed: 1988-05-03
Abstract: The proposal is for an aerostatic bearing, the bearing shell of which is divided into a plurality of segments (2) which are supported independently of one another in a resilient manner (7). The segments of the bearing shells can thus follow and compensate for small irregularities in the geometrical shape of the shaft (3) and the load-bearing capacity of the bearing can be evened out by varying the pressure of the supporting gas fed in through channels (5) and/or by adjusting (8) the spring force around the circumference. By reducing the porosity of the bearing-shell segments (these being produced from a sintered metal, being compacted at their surface and then etched for pore formation) from their front edge (V), the edge facing in the direction opposite to the direction of rotation of the shaft, to the rear edge (H), non-uniform lift of the said segments from the shaft (3) can be achieved. Aerodynamically generated forces which increase the load-bearing capacity of the bearing arise in the wedge-shaped gap (9) thus formed. <IMAGE>

Title: Process and device in a paper machine cylinder-dryer in which a two-fabric path is used
Inventor: ESKELINEN PEKKA DIPL ING
IPC: D21F5/04
Filed: 1988-06-01
Abstract: Process in a paper machine cylinder-dryer in which the web is guided by using an upper fabric (40) on the upper cylinders and a lower fabric (30) on the lower cylinders. The fabrics (30, 40) are guided by the surface of the drying cylinders and by guide rolls (34, 35, 44) arranged in their interspaces in such a way that the web (W) has direct drying contact with the surface of the upper cylinders (41, 42) in the upper row of cylinders by means of being pressed on by the upper fabric (40), and is pressed against the surface of the lower cylinders (31, 32) by the lower fabric (30). As the web (W) and the drying fabric (30, 40) leave the drying cylinder (31, 41), the web (W) is sucked firmly on to the drying fabric (30, 40) by sucking through the drying fabric (30, 40) in a low-pressure region (A-, N-) arranged at the relevant position of the drying fabric draw in such a way that the length of the free draw (Wp) of the web is significantly shortened. The said low-pressure region (A-, N-) is generated by means of an air-blast which is blown through a passage (R) bounded by the outer surface of the fabric (30, 40) on the drying cylinder (31, 32, 41, 42) and a wall surface (14) and elongated (L) in the blast direction. By means of the relevant passage (R), the boundary-layer flow following the drying fabric (30, 40) is directed in the opposite direction with respect to the draw of the fabric (30, 40) and, in the spaces available on the back of the said passage (R), a...

Patent DE-3834487-A1 (DE)
Inventor: SCHMIDTKE WOLFGANG
IPC: B02C18/14
Filed: 1988-10-11
Abstract: The invention relates to a method and an apparatus for the simultaneous grinding and cooling of solid substances by means of a cutting mixer. The cutting mixer is evacuated in at least one vacuum stage, and refrigerated liquefied gas is introduced into the cutting mixer in at least one cooling stage. In order to optimise the method, it is proposed to draw off the waste gas arising during the cooling stage. A waste gas valve 12 is to this end advantageously installed which is closed before the end of the vacuum stage and opens after the latter is complete in order to draw off the waste gas arising during the cooling. <IMAGE>

Title: Floor covering and method for its manufacture
Inventor: BOELLING DIETRICH
IPC: D04H1/48
Filed: 1989-02-15
Abstract: In order to manufacture a floor covering consisting of two layers of needled felt, of which the top layer (10) is structured on its top side, the bottom layer (11) is needled into the top layer (10) from the direction of the underside of the said structured top layer (10). The needle depth is in this case considerably less than the thickness of the top layer (10). By means of needling the two layers together from the back of the top layer, the structuring (13) of this top layer is not damaged. Following this needling together, an additional joining of the two layers is effected by impregnating them with a binding agent through the top layer (10). <IMAGE>

Patent DE-3921021-A1 (DE)
Inventor: LANGE RUDOLF
IPC: G01F1/06
Filed: 1989-06-27
Abstract: Described is single-jet or multi-jet impeller-type water meter with a device for compensating for errors due to ageing, the device having one or more pipes, or flow-retarding ribs with grooves, located in a measurement chamber. When the meter becomes dirty, the increase in rpm this causes is automatically compensated for since the flow cross-section of the pipes is simultaneously decreased, thus leading to increased throttle losses, or the effective cross-section of the flow-retarding ribs is increased. These devices can also be used for the initial adjustment of the meter.
