Abstract: A process is disclosed for producing and feeding wash water in a washing installation, in particular a car washing installation (1), according to which the wash water is used in at least one washing process for cleaning a motor vehicle (28) or the like and is evacuated after each washing process. In order to use only relatively reduced amounts of wash water, the evacuated wash water is reused in an essentially closed water circuit for successive washing processes. The evacuated wash water is collected and supplied to a filtering installation or similar processing device and at least part of the filtrate generated in the processing device or pure water thus produced is supplied to at least one ulterior washing process as wash water. Also disclosed is a washing installation, in particular a car washing installation (1), with at least one spray head or similar wash water outlet (2, 3, 4, 5) which applies the wash water to a motor vehicle (28) or similar object to be cleaned. The disclosed washing installation is characterized in that it has an arrangement for collecting the wash water after each washing process, the collecting arrangement (6) is linked with at least one device for processing at least part of the collected water and the filtrate or pure water outlet (10) of the processing device is linked with at least one wash water outlet of the washing installation. The required wash water can thus be used in the disclosed washing installation in a practically closed water circuit.

Filed: 1992-07-02
Abstract: Multi-layered hot-water storage tank with countercurrent heat exchanger without external energy source, for layered charging or discharging. Two techniques fulfil this task:   a) A countercurrent heat exchanger built into the storage tank, by means of which the stored water falls due to thermosyphon forces in the case of a domestic-water exchanger, or rises in the case of a charging exchanger. b) The domestic water drives a mini-turbine (10) or a water motor, by means of which a mini-pump (11) is driven, the latter sending hot stored water through a countercurrent heat exchanger (12) in which the domestic water is heated and the stored water is cooled. The cooled stored water is passed into the cooler region of the storage tank again.   <IMAGE>

Title: Test carrier/analysis system for analysing a constituent of a liquid sample
Inventor: BOLDUAN FRANZ DIPL PHYS DR RER
IPC: G01N21/01
Filed: 1993-02-19
Abstract: Test carrier/analysis system for analysing a constituent of a liquid sample, in particular a body fluid. The system includes test carriers having at least one test section which contains reagents. The reaction of the reagents with the sample leads to an optically measurable change in a detection layer of the test carrier. Furthermore, the system comprises an evaluation device (1) having a test carrier receptacle (2) and an optical measuring device (5) having an optotransmitter (11) and an optoreceiver (13) for measuring the optically measurable change. A measuring signal is fed to an electronic evaluation system (6) for conversion into an analytical value. In order to improve the reliability of the exchange of data with the evaluation device (1) and to realise a data interface at the evaluation device without appreciable additional costs, the system has a data transfer module (3) having at least one optotransmitter (20) or optoreceiver (21), which acts as a photooptical (light-optical) data transfer element (22) and can be inserted instead of a test carrier into the test carrier receptacle (2). The exchange of data between the evaluation device (1) and the data transfer module (3) takes place in this case via the data interface (33) formed by the optotransmitter (11) or the optoreceiver (13) of the optical measuring device (5) and the optical data transfer element (22) of the data transfer module (3). <IMAGE>

Title: Linear drive
Inventor: KOCH DIETMAR
IPC: F16H25/20
Filed: 1993-05-14
Abstract: The invention, which relates to a linear drive having a spindle/nut combination, consisting of a spindle and a spindle nut which is arranged such that it can be screwed along the spindle, and having an electrical drive motor for producing a rotational relative movement between the spindle and the spindle nut, the rotation direction of which electrical drive motor is electrically variable, is based on the object of specifying a linear drive which makes it possible to limit the movement of the nut in a simple manner and at a low production cost. This object is achieved in that one or more electrically conductive conductor tracks, with which contact can be made over their longitudinal extent, are arranged parallel to the movement path of the axially longitudinally moving part of the spindle/nut combination. In this case, the conductor tracks are provided with sliding contacts (wipers) which make contact in a sliding manner and are connected at least indirectly to the axially longitudinally moving part. Furthermore, means are provided which prevent any electrical contact between the sliding contact and the conductor track on the conductor track or one of the conductor tracks at a first position and on the conductor track or one of the conductor tracks at a second position, the distance between the two positions being proportional to the movement length of the axially moving part.   <IMAGE>
