Inventor: JANSEN KURT DR
IPC: G01P5/20
Filed: 1988-08-17
Abstract: In a process and device for measuring a flow rate, the beam preferably emitted by a semiconductor laser (4) is split in the visible or infra-red range by means of a collimating lens system (5) and a twin hole diaphragm (6) connected downstream of the latter into two partial beams (1, 2) which are guided through the flow containing scattering centres. The total intensity of the partial beams or the reflected parts thereof passing through the flow is measured preferably by a photoelectric cell (7) and then amplified (8, 9). The autocorrelation function is derived from the measurement signal and processed (10, 11) in order to determine the transit time of the scattering centres through the partial beams. The process and device also yield satisfactory results in the case of high scattering particle densities and unknown flow profiles. Hardware costs are minimal and only a fairly small amount of data need to be evaluated, because only one receiving unit is required and only one measurement signal has to be evaluated.

Title: Single-pole plug with a screen connection, of coaxial type
Inventor: WEINGARTNER BERNHARD DIPL ING
IPC: H01R13/646
Filed: 1988-10-07
Abstract: The single-pole plug of coaxial type has a central contact pin (1) which is held by an insulating body (4, 5), and, in addition, a cylindrical outer sleeve (14) which is used as an outer contact for the screen connection. This cylindrical sleeve (14) is mounted such that it can be displaced in the axial direction against the force of a spring (12) and relative to the central contact pin (1). The spring (12) holds the sleeve (14) in a position displaced with respect to the contact pin (1), when the plug is not being used. The front edge (15) of the cylindrical sleeve is located approximately in the region of the free front end of the central contact pin (1) when this sleeve (14) is pushed forward by the force of the spring (12). When the plug is combined with the corresponding plug socket, this results in the earth contact being produced before the contact elements carrying the signal voltage are combined with one another. When the plug connection is released, the contact elements carrying the signal voltage are disconnected before the earth contacts are released. <IMAGE>

Title: Process for regenerating used wash liquors based on phosphate-containing detergents
Inventor: PAUDERT ROMANN DR
IPC: D06F39/08
Filed: 1989-03-28
Abstract: The invention relates to a process for regenerating used wash liquors based on phosphate-containing detergents for liquor re-use in washing processes. The process of the invention can be used in particular in commercial laundries. The invention provides that, following completion of a wash cycle, a partial precipitation of the polyphosphates and surfactants from the wash liquor is effected using compounds containing alkaline earth metal ions, after which a sedimentation of the soil-laden precipitation product and subsequent removal of the decantate for liquor re-use are effected. This regenerates the wash liquor, and soil and fluff is separated off with the precipitate without further processing stages. An advantageous precipitant is the MgCl2 waste liquor from the potash industry.

Title: Picture producing device and method for imaging an original picture and a bar code
Inventor: WATANABE JUNJI
IPC: G03G15/047
Filed: 1989-04-14
Abstract: In an electronic copier, a picture on an original is optically scanned by means of an optical system which contains a first slot (22) provided with an exposure lamp (14). The picture obtained with the optical system is generated on the surface of a tubular photo-conductive drum (36) which rotates in a predetermined direction. Bar code data which are not contained in the original picture are written onto the original picture at a desired location. In this way, the bar code data are entered from an operating panel (80) of the machine into the copier. The light which is guided from the optical system to the drum (36) is partly screened by a closure device (122). A bar code generator (147) generates pattern data which correspond to the bar code data which have been entered, the pattern data being entered at that point of the drum surface which is screened from the incident light by the closure device. A writing unit (74) is used for writing the pattern data. The original picture and the pattern data which have been generated on the drum surface are developed and transferred to a recording paper. <IMAGE>

Title: Biological clarifier vessel using aerobic-selective principle - comprises insulated vertical cylindrical vessel divided into concentric zones for aeration, clarification and sedimentation
Inventor: ZIMMER ERICH HELMUT DIPL ING
IPC: C02F3/12
Filed: 1989-05-20
Abstract: The clarifier vessel is insulated and is divided by internal partitions into a number of concentric zones. The central zone contains the aeration device, the intermediate zone contains the packing material, and the outer zone acts a clarifying and settling area. The partition between the intermediate and outer zones is designed to optimise the recovery of heat, and a submersible pump is provided in the central zone which discharges upwards so that the fluid in the clarifier is circulated through the packing material. Alternatively, the packing material may itself be circulated through the pump. The aeration device is in the form of an air-lift pump. A gas collection hood discharging to the central zone may be provided in the outer zone. The packing material consists of short sections of plastic pipe containing three internal cylindrical surfaces. USE/ADVANTAGE - Clarifiers of this type are used in the purification of waste water, sludges etc. The proposed system of operation provides a simple and economical construction and is suitable for a wide range of applications. The division of the vessel into zones affords an intensively aerated inner zone where mixing and nitrification take place, a less aerated upper reactor bed zone where nitrification continues, a lower reactor bed zone where de-nitrification and sedimentation take place, and a bottom deposition zone where de-nitrification and sedimentation continue.  A high rate of treatment is achieved and the risk of blockage of the reactor bed is reduced.
