Title: Air-purifying device for hospital beds
Inventor: HOELTER HEINZ DIPL ING
IPC: F24F8/108
Filed: 1986-04-12
Abstract: It is known that bed-ridden patients are a frequent source of nuisance to the environment due to unpleasant odours. There have already been proposed devices which are directly connected under the bed cover in order to eliminate the unpleasant odours. However, continuous aspiration under the bed cover may lead to hypothermia of the patient, so that it must be rejected in many cases. In order to avoid these disadvantages the invention proposes an air-purifying device which comprises a purification cartridge (3) on the suction side of a fan (4) and a purification cartridge (5) on the pressure side of the fan (4). The purification cartridges (3, 5) are designed as combined sound absorbers/chemisorption filters. The filter cartridge (3) is preferably designed as a multi-layer chemisorption filter, the layers comprising alkaline and acidic compositions having bactericidal and odour-absorbing effects. <IMAGE>

Patent DE-3714016-A1 (DE)
Title: Process for the treatment of scrubbing water from a gas scrubber
Inventor: FELGENER GERD W DIPL ING
IPC: C02F11/08
Filed: 1987-04-27
Abstract: In the process for the treatment of effluent from scrubbing the crude gas from the gasification of carbonaceous fuel, the crude gas is contacted under elevated pressure and at elevated temperature with the scrubbing water, the water being laden with organic and inorganic components. The object is to let down the laden effluent with the lowest possible equipment cost and at the same time to save energy and to improve the purification of the water. For this purpose, the laden scrubbing water (7) is first contacted in a wet oxidation vessel (11) with air (15) at temperatures above 100@C, before it is let down into a stripping vessel (19) to approximately atmospheric pressure. For steadying, the laden scrubbing water (7) is passed through a feed vessel (8) upstream of the wet oxidation (11). The stripping of the laden and let-down effluent (21) is assisted by caustic soda solution (22) and steam (23). The top product (24) from stripping is condensed to obtain strong aqueous NH3 (28). The bottom product (33) is fed to a settler (36), from which sedimented solids (27) and purified water (4) are taken off. <IMAGE>

Title: Opposed-piston internal combustion engine having a central control groove or separated scavenging and charging
Inventor: EICKMANN KARL
IPC: F02B3/02
Filed: 1987-06-20
Abstract: In an opposed-piston assembly in which a low-mass piston reciprocates in coaxial cylinders, the preferably hollow piston rod which connects the pistons, which are preferably thin, obliquely set plates having a low mass, is provided with a single control groove which controls successive fluid intakes from an inlet in the central housing between the cylinders in such a way that the inlet fluid flows into one of the cylinders at one time and into the other cylinder at a subsequent time. The plurality of control grooves in published patent applications of the inventor are thus reduced to a single control groove, the flow cross-sections are designed to have more favourable streamlining, the assembly is simplified, manufacturing costs are reduced and, at the same time, the efficiency and power output at a given weight of the assembly, which can be used particularly as a high-performance internal combustion engine, are increased. To increase the power output per given weight and dimensions and also to increase efficiency and environmentally friendly operation by improving combustion and reducing toxic exhaust fumes, the scavenging of the cylinder chambers in the advantageous embodiment is separated from the charging of the cylinder chambers both in time and space so that the engine in this embodiment achieves the same or approximately the same cleanliness of operation as the four-stroke engine. <IMAGE>

This fan is only connected when the filter unit is switched on. <IMAGE>
Patent DE-3721500-A1 (DE)
Title: Retractable integrated tyre spike system (integrated spike system)
Inventor: AGOT ERIC JOEL DIPL ING
IPC: B60C11/16
Filed: 1987-06-30
Abstract: Conventional single-purpose and universal tyres which have to be changed when the season changes have a disadvantage that it is virtually impossible to carry out short-term adaptations to changes in the state of the road. This is due to the difficult, and often time-consuming, procedure for each change of tyre. Sometimes, the condition of the road or underlying surface changes rather suddenly or during a journey. For the abovementioned reasons I have invented the concept of the integrated spike system. The integrated spike system (stands for retractable integrated tyre spike system) embodies a novel invention by means of which I would like to make a variable tyre system available to all classes of car drivers. The configurations which are produced as a result of the adjustment of the tyres by the integrated spike system permit all the driving properties of both summer and winter tyres to be simulated. The integrated spike system is provided in three versions, namely a manual, semi-automatic and completely automatic version. Here, the manual version is to be the cheapest one, the fully automatic the most expensive. The pneumatic activation of the integrated spike system is explained here although the other possible activation means have been specified in the patent claims.
