Patent DE-19812009-A1 (DE)
Title: Flat solar still with inclined irregular collector floor
Inventor: ROSENDAHL WILFRIED
IPC: F24S10/60
Filed: 1998-03-19
Abstract: The flat solar still has an inclined irregular collector floor covered by a fleece mat which improves heat capture characteristics. The solar still has a flat solar collector housing which is made of a thermally insulating material, covered by a transparent window of foam glass. The incoming water is distributed by a jet pipe with wick at the heat of the collector. The water is then sprinkled or seeps slowly onto the collector floor. The collector base is black in color and absorbs solar radiation. The collector floor has an irregular surface which slows the rate at which water seeps to collection gutter and sump drain outlet. The collector floor has a matting of black non-woven fibers which allows for partial passage of solar radiation to the collector floor. Water vapor collects on the transparent overhead panel and drains through horizontal and vertical channels to a gutter and a drain for collection. The overhead transparent panel is hinged on one edge and may be opened for maintenance and cleaning.

Title: Manual control for laboratory micro-motors with tool collet chuck
Inventor: FAVONIO ANGELO
IPC: B23B31/00
Filed: 1998-04-17
Abstract: The collet chuck (20) is driven by means of a shaft (18,23) of the control and pivot mounted in a front or back bearing (17,17a).

Abstract: The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate. Process for removing acidic components, e.g. carbon dioxide, hydrogen sulfide, COS, carbon disulfide and mercaptans from gases comprises contacting the crude gas with an adsorbent obtaining a pure gas deficient in acidic gas components and an absorbent charged with acidic gas components. The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate.
Patent DE-19831334-A1 (DE)
Title: Squeeze drying of wet solids
IPC: B30B9/18
Filed: 1998-07-13
Abstract: Compression is provided by a screw conveyor transporting the material through four distinct sections: M - material gathering, V - consolidation, K - compression and a dry material transport section (4).  Section (4) is partially closed by a conical plug (5) that is held in position by a hydraulic linkage (7,8). The gap (20) through which the material passes is determined by the pressure difference between the material and the hydraulic linkage and is therefore variable by varying the hydraulic force. A further variation, designed to increase the dwell time of the material, is possible by changing the length of section (4) since the tubing is formed by two half-shells that can be interchanged. Similarly the perforated conical compression section (3) can be interchanged so that sieves with different meshes can be used, or simply to permit easy cleaning.

Abstract: The sack (50) comprises a base, two broad sack walls (41), two narrower walls (42) folded onto themselves and a sack opening with a closure (48) comprising two first flaps (21) connected to the broad walls and two second flaps (22) folded centrally onto themselves connected to the narrower walls. The faces of gussets (23,24) at the ends of both first and second flaps lie against each other to form double layer sealing corners (47) which are bonded or welded together.  Independent claims are made for: a) a process for producing a paper sack in which an adhesively coated transverse edge (15) of the paper sheet is folded over parallel to the latter edge and overlapped with the opposing edge to form a sack open at both ends, four gusset shaped adhesive applications are made on a longitudinal edge (18) at the sack closure (48) which when the closure flaps (21,22) are folded over onto each other bonds the gussets (23,24) together and forms sealing corners (47); b) a plastic film sack manufacturing process in which a sack open at both ends is produced, four gusset shaped overlaps are created along a longitudinal edge between the sack body and the closure and gusset faces bordered by the edge are welded together to form double layer sealing corners. Preferred Features: A boundary line of the first gusset (23) is formed by the connecting edge (18) of each first flap (21) and each corresponding boundary edge of the second gusset (24) runs at a right angle to the free long edge of each second closure flap. After folding the sack closure the corresponding boundary edges run parallel to the sack opening. The flaps and gussets are bordered either by a common folding edge (25) at 45 deg  to the connecting edge or by cut edges starting from the connecting edges.

Abstract: The invention relates to a motor vehicle tail light assembly with linear optics, with a plurality of reflectors and electric bulbs assigned to them to form a tail light, a brake light and a fog tail light, and further with reflectors and electric bulbs for a direction signal light and a back-up light and with light diffusers and optical disks. Individual sections of the light diffusers have linearly arranged retroreflective elements to produce the linear optics. The aim of the invention is to design such a tail light assembly in such a manner that the design possibilities are wider for the required number of signal lights and that the assembly is as compact as possible while still having a harmonious appearance. To this end, the tail light consists of a plurality of reflectors (1-4) and electric bulbs (16; 17). At least two of said reflectors (1, 4) are provided with electric bulbs (16) with two wattages. One reflector (1) with the electric bulb (16) switched to higher wattage forms the brake light and the other reflector (4) forms the fog tail light. Said reflectors (1, 4) are arranged at a certain distance to each other which at least meets the legally required minimum distance (A) between the brake light and the fog tail light. The sections of the light diffusers with the retroreflective elements are arranged in the area between the reflector (1) and the reflector (4).
