Title: Process and device for the preparation of coloured proofs in multicolour printing
Inventor: JUNG EGGERT
IPC: H04N1/60
Filed: 1982-06-04
Granted: 1986-02-20
Abstract: Method and apparatus for recording color pictures wherein color proofs are made before the actual printing for quality control in multicolor printing processes. The color pictures are exposed on a chromatic material wherein the exposed colors must coincide with the colors which are later to be printed on paper. So as to achieve the color equivalent color picture exposure, the required color density values for the chromatic material of the selected printed and exposed colors are identified with a visual or mensurational comparison of the CIE coordinates. The identified color density values for the exposed colors are allocated to the corresponding color separation values of the colors to be printed and during recording the allocated color density values are utilized instead of the color separation values and are converted into signals for driving a color exposure unit for example a proof recorder.

Title: Flow control device with integrated pressure detector
Inventor: D AGOSTINO GUY
IPC: G05D7/01
Filed: 1983-06-02
Granted: 1987-11-19
Abstract: Fuel from a centrifugal pump enters the regulator at an inlet and leaves via an outlet. A proportioning piston slides in a hollow cylinder whose upstream chamber is filled at a first pressure. The fuel passes through a proportioning oriface between a shoulder of the cylinder and a tapered part of the piston, filling the downstream chamber at a second pressure. The pressure drop is maintained constant by a detector and regulating valve placed end-to-end inside the hollow piston. The upstream pressure is communicated via an external link to a bellows operating a slider (24) which corrects the pressure difference.

Title: Interface checking apparatus
Inventor: JACKOWSKI STEFAN PETER
IPC: G01R31/28
Filed: 1984-05-25
Granted: 1987-12-17
Abstract: Testing of interface lines (14) interconnecting a first circuit (10) to a second circuit. When an abnormal circuit condition affects the interface lines, such as an open circuit or a short circuit condition, the operation of the first and second circuit is detrimentally affected. The present invention determines the existence of abnormal circuit conditions in one or more lines of a group of interface lines without the utilization of redundant duplex lines to perform the determination. The interface lines are subdivided into a first group (14a), which are used when the apparatus of the present invention is being used to locate abnormal circuit conditions, and a second group (14b), which is not used when the apparatus of the present invention is being used to locate abnormal circuit conditions. Each line of the first group is connected to a corresponding input terminal of a first exclusive OR gate (16) and a second exclusive OR gate (18) at an input side and an output side, respectively. The first and second OR gates are input to a matching circuit (20), an output signal therefrom indicating the existence of an abnormal circuit condition in the first group of lines. As a result, since the lines of the first group are used when the apparatus of the present invention is being used to locate abnormal circuit conditions, each line of the first group is tested individually for the presence of an abnormal circuit condition. However, since the lines of the second group are not used when the apparatus of the present invention is locating abnormal circuit conditions, the lines of the second group are tested, collectively, as a group, for the presence of an abnormal circuit condition. One line (11) of the first group is connected to an input side of the second group. The output side of the second group is connected to an additional input terminal of the second exclusive OR gate. An output signal from the matching circuit indicates the existence of an abnormal circuit condition in at least one line of either one or both of the first and second group of lines.

Title: Process for the multiple use of a copper wire as an electrode wire in electric-resistance longitudinal seam welding
Inventor: WEIL WOLFGANG HERMANN
IPC: B23K11/30
Filed: 1985-04-22
Granted: 1989-02-16
Abstract: The copper wires employed for electrical resistance seam welding of tinned sheet metal with the help of wire electrodes until now had to be taken back to the smelter as old metal after a few applications. The additional operating costs associated with this were until now unavoidable for long seam resistance welding of tinned sheet metal since multiple uses or applications of the copper wire for resistance seam welding have proven to be impossible in spite of years of research. The problem of these additional operating costs can be solved such that new copper wires with a reduced diameter can be directly drawn from the copper wire employed as wire electrodes for resistance seam welding after their use in welding. These wires then, for example, can be used as signal conductors or as windings. The properties of these wires are totally in accord with copper wires that are directly drawn from new copper. By this process, the additional operating costs mentioned above are substantially reduced and in many cases are even totally eliminated.

IPC: G21F9/18
Filed: 1985-12-19
Granted: 1990-04-19
Abstract: Paramagnetic metals are separated from aqueous media containing them in low concentration by first fixing the metals on bacterial yeast or other cells so as to render the cells magnetic, and then recovering the cells by a high gradient magnetic separation technique. The metal and the cells are contacted in the presence of a compound which is converted by the cells into a product which interacts with the metal and causes it to become bound to the cells. The process is particularly useful for removing low concentrations of highly toxic metals, e.g. uranium, from industrial effluents containing them.
