Title: Nitrate removal from drinking water - by regeneratable resin with computer control for cyclically operating tanks
Inventor: PLUESS FRITZ
IPC: B01J49/00
Filed: 1988-05-05
Abstract: Undesirably high nitrate content in drinking water is removed by contact with anion-exchange resin resting on a perforated support and occupying 60-80% of the capacity of an upright tank, forming one of a set of two or more alternating between water treatment and regeneration stages. A bed of exhausted resin is loosened by compressed air or flushing water and then chemically regenerated, e.g. by 10% NaCl soln. After regeneration and flushing with raw water, which may be heated, the tank is ready for normal operation. Regenerating chemical supply, circulation of regenerant, and water feed and heating are all controlled by a computer receiving flow data from tanks coupled in series or parallel. USE - Removes excessive nitrate, which can now affect considerable areas and is esp. harmful for small children or certain patients.
Patent CH-687737-A5 (CH)
Inventor: TORMA MIKAEL
IPC: A47J31/40
Filed: 1990-11-16
Abstract: The brewing device (1) for a coffee machine comprises two side plates (3) for fastening the individual parts and for guiding the movable parts. A brewing chamber (32) is guided with pins (24, 28) in angular grooves (26, 30) which are arranged in the side plates. The intersecting grooves (26, 30) in one side plate, like the pins guided in them, have a depth or height which are different from one another, so that at the point of intersection of the grooves the pins cannot pass into the wrong groove. Guided on a threaded rod (14), which is driven by a motor (4), is a nut, connected to two bows (21), for displacing the brewing chamber (32) from a coffee-filling position into a brewing position. A sieve plate (33), which is connected to a piston rod (35) and situated in the brewing cylinder (31) of the brewing chamber (32), is displaceable in height with the aid of a cable pull (41, 46, 47, 59, 50). The 2:1 transmission ratio of the cable pull makes possible a small construction size. The linear drive means (14) with the multi-axial traction and pressure means (21) makes possible a variable brewing cylinder volume. <IMAGE>

Title: Gas discharge grid in a co-current gas generator
Inventor: JACCARD LEON
IPC: C10J3/36
Filed: 1992-12-12
Abstract: The invention relates to a gas discharge grid in a gas generator, which comprises an essentially cylindrically shaped chamber (1) containing a screw (3). The grid (7) serves to separate the gas formed in the gas generator from the material (charcoal) in the gasification phase. The grid (7) is of annular shape and has gas passage slots (11), whose cross-section has the minimum width in the interior of the grid (7) and increases towards the outside of the grid (7). Owing to the proposed increase in the cross-section of the gas passage through the slots (11), the danger of blockage of the grid (7) is effectively eliminated. Furthermore, the grid is easy to fabricate and is resistant to the high temperatures prevailing in the interior of the gas generator. <IMAGE>

IPC: F24S20/20
Filed: 1981-06-23
Abstract: A reflector element, parabolically deformable under pressure, has a first elastic diaphragm (1), which has a reflective layer and a second transparent diaphragm (9). The two diaphragms are clamped along their periphery in a bearing ring (3) and form a pressure tight chamber (10). The bearing ring is arranged like a wheel by means of two cable arrangements (7, 8) on a central collector axis (4). This is pivotably mounted at its foot in a joint (5), so that the bearing ring (3) can be rolled on a support base (11), which permits azimuth adjustment of the collector. For adjustment of the angle of elevation, the joint (5) is height adjustable. The collector axis (4) at its other end carries a heat absorption unit (2), which is arranged in the area of the focal point of the reflector. In order to reduce reflection losses, the transparent diaphragm (9) runs essentially perpendicular to the direction of the incident light, which is achieved by supporting it against the front cable arrangement (7).
