Title: Pilot-controlled slider valve for cylinder-piston unit
Inventor: KROEGER DIRK DIPL ING
IPC: F15B15/22
Filed: 1997-08-28
Abstract: The valve has a housing (1) with two pressure unions (2) communicating with respective pressure chambers, between which a valve slider (3) with external sealing rings is located. The slider is driven at one end by a cylinder-piston unit also integrated in the housing whose cylinder space is connected by a working channel to a solenoid pilot valve.  A piston arrangement of the piston-cylinder unit consists of a larger short-stroke hollow piston whose outer surface comes to the arrangement via an annular sealing element held there sealing on the wall of the cylinder space. Its inner surface forms a cylinder for a smaller long-stroke slider piston (13) which is sealed against the inner surface of the hollow piston by an annular sealing element (17) held on the slider piston. The slider piston communicates with the valve slider.

Title: Analysis apparatus for high-temperature plasma pulse
Inventor: FALK HEINZ PROF DR
IPC: G01J3/443
Filed: 1997-12-03
Abstract: In an apparatus to register and quantify the concentration of elements in solid samples, the sample is evaporated and the vapors are excited within a high-temperature plasma pulse, emitting a signal impulse which is then analyzed to derive the required analytical information. In an apparatus to register and quantify the concentration of elements in solid samples, the sample is evaporated and the vapors are excited within a high-temperature plasma pulse, emitting a signal impulse which is then analyzed to derive the required analytical information. The apparatus facilitates a breakdown of the impulse amplitude into one portion which indicates the homogenous distribution of elements present, and another portion indicating the non-homogenous distribution of elements present. With this information provides an analytical distinction between dissolved and non-dissolved portions of a substance in a sample. In addition, the process facilitates a correlation between the individual impulses from different element channels, enabling a deduction as to the non-homogenous composition of a sample. The apparatus facilitates a both qualitative characterization of the non-homogenous nature and the relative proportions of the elements present.

Patent DE-19755652-A1 (DE)
Title: Electrostatic powder coating is carried out in apparatus charging dilute fluidized cloud induced by ejector-atomizer, with safety precautions against high voltage and fire
IPC: B05D1/00
Filed: 1997-12-08
Abstract: In a spraying gap (7), reduced pressure is produced by compressed air supplied (1) to a nozzle through a tube. Into the gap a powder suspension is discharged. This is induced through suction openings, from a fluidized powder bed. At the gap, the suspension is atomized to a cloud of powder. Conductive electrodes (8) are connected to high electrical potential (11). Thus a cloud of powder is charged electrostatically. Charged powder particles deposit on to an object immersed in the cloud.  An Independent claim is included for corresponding equipment. Preferred features: A dilute fluidized powder layer at a low height of e.g. 10 cm is induced basally through a suction funnel using little air. The suspension is charged to \!5-\!15 kV. It passes via powder supply channels in the pipe and is atomized at a baffle, to deposit on the earthed object. The cloud, free of ions, overcomes the Faraday effect and penetrates into the cavity. Charging electrodes (8) and their supply are covered by insulating panels hung completely over the entire wall of the vessel (4), up to the (small) height of the powder layer. They separate the coating zone from the parts at high voltage, increasing safety. In the suction funnel a honeycomb electrode close to the conductive electrode is connected to another high voltage source. It superimposes charge, increasing that of the cloud. Further suction funnels, on pivoting arms with adjustable baffles cover the base. Powder clouds are produced for the sides of the earthed object. Further baffle and honeycomb arrangements are indicated, which reinforce coating. An insulant partition with openings for return flow of powder increases safety. The suction funnel is slowly raised and lowered, achieving a more dense charged powder cloud. The vessel is made of non-combustible material e.g. TROVICEL 200 (RTM).

Title: Colour picture transmission processing apparatus
Inventor: KOUKI ISHIHARA
IPC: H04N1/64
Filed: 1998-06-03
Abstract: The apparatus includes a computing unit for counting the number of colours as the numbers of different colour pixel values during scanning pixels of colour picture data for each row. A palette forming unit is provided which has a storage area for representative colours of a preset number of entries. A subtractive colour palette is formed by storing full colour pixel values as representative colours in the entries when the number of colours is counted upwardly. A transmission format discrimination unit counts the number of transmission pixels to the end of a previous row, if the number of colours exceeds a preset number of entries of the subtractive colour palette.  Transmission data according to the full colour format of the number of the transmission pixels are compared with transmission data according to the palette format. Data transmission is instructed according to the format of a smaller transmission data amount. A data transmission unit forms and transmits the palette format data which include halftone codes and representative colours of the subtractive colour palette if an instruction of a data transmission in the palette format is received. Full colour format data are formed and transmitted including colour pixels, when an instruction of data transmission in the full colour format is received.
