Abstract: In a method for copying retouch in color picture reproduction, color values are initially acquired by image-point-by-image-point trichromatic color picture scanning and digitization. The color values are deposited in a storage medium and are addressable by image point coordinates. With the coordinate pen of a coordinate acquisition means, the retoucher first marks a read point within a first image region from which a pattern is to be taken and a write point within a second image region into which the pattern is to be copied with image point precision. A distance between the read and write points is determined from the acquired image point coordinates and is fixed. The retoucher then acquires all image point coordinates within the first image region with the assistance of a coordinate pen. The image point coordinates of those image points within the second image region exhibiting the respective fixed distance from the acquired image points are simultaneously identified and a double coordinate pen is thus simulated. For precise pattern transfer, the color values of the first image region addressed with the assistance of the double coordinate pen are replaced image-point-by-image-point by the simultaneously addressed color values of the second image region or by values calculated from the color values.

Abstract: The device comprises an expandable chamber (13) having an outlet (23) for connection to a facepiece, for example face mask (26) and an inlet (12) connected to pump means (2, 3, 4, 5) for drawing ambient air into the device through a filter (8) and pumping it into the chamber. In use the wearer of the face mask draws air from the chamber and that air is replenished by operation of the pump means. 
     Means (19) are provided for sensing the degree of expansion of the expandable chamber and are coupled with means (22) for varying the power supplied to the pump means so that the pump means supplies only sufficient filtered air to maintain the chamber inflated. A bias is provided on the chamber advantageously coupled with the sensing means for maintaining a positive pressure in the chamber. 
     The device allows close control of the amount of air passing through the respirator so as to substantially reduce the amount of air which is filtered but unbreathed to extend the life of the filter means.

Abstract: A process for producing neutral calcium hypochlorite comprising admixing lime, an alkali metal hypochlorite and dibasic calcium hypochlorite crystals in a mixing zone slurry. The mixing zone slurry is reacted with chlorine to form a paste of neutral calcium hypochlorite. The paste is then separated into a cake of neutral calcium hypochlorite and a paste liquor. A slurry of lime is fed to a crystallizer to react with the paste liquor to form a slurry of dibasic calcium hypochlorite crystals in a mother liquor. Crystals of dibasic calcium hypochlorite are then separated from the dibasic mother liquor and recycled to the mixing zone. 
     In a modification, the invention provides a process including the preliminary steps of reacting an aqueous slurry of lime containing insoluble impurities with chlorine in a first crystallizer to form a first slurry of dibasic calcium hypochlorite crystals and insoluble impurities in a calcium chloride mother liquor. The insoluble impurities are separated from the first slurry of dibasic calcium hypochlorite crystals by employing separation means for classifying solids with respect to particle size. Dibasic calcium hypochlorite crystals are then separated from the calcium chloride mother liquor and admixed with a alkali metal hypochlorite and recycle dibasic calcium hypochlorite crystals in the mixing zone to form the mixing zone slurry.

Abstract: A method and an apparatus for controlling the reduction ratio of a continuously variable transmission are disclosed wherein when an actual engine coolant temperature indicative signal is greater than or equal to a predetermined value indicative signal, a desired optimum reduction ratio signal is obtained by retrieving the desired optimum reduction ratio signal data stored in a memory versus an engine load and a vehicle speed. When the actual engine coolant temperature indicative signal is less than the predetermined value indicative signal, the same desired optimum reduction ratio signal data are retrieved based on a corrected signal which is obtained by correcting an engine load indicative signal or a vehicle speed indicative signal in order to provide a larger reduction ratio. Alternatively, another optimum reduction ratio signal data are retrieved when the actual engine coolant temperature indicative signal is less than the predetermined value indicative signal.

Abstract: Rolling bearings applied in the engines are subjected to relatively high temperature fluctuation i.e. on the levels between 500°C to 600°C. Therefore extremely good resistance against such temperature-fluctuations and corrosion as well is of paramount importance. 
     It now has been found that these requirements can be met by subjecting M 2  steel to superheated steam which forms a thin layer mainly of Fe 3 0 4 . This layer much increases the resistance against corrosion which feature combined with the natural resistance of M 2  steel against high temperature results into an excellent bearing element for above circumstances as tests have proven.

Filed: 1983-11-21
Abstract: For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt. The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C). Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91) (for gas or fluidised powder). Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25). Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91). Wire is fed along passage (B) to the melt: when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt.A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.

Abstract: This invention is directed to a method of supporting and locating optical elements in their axial location. Said method includes the steps of seperating optical elements by spacers (16) with matching surfaces (20) to the lenses. These spacers (16) have an optical axis similar to a lens which is positioned in coincidence with the mating lens optical axis (15). This is accomplished by rotating the spacer about its first surface center of curvature (C2) until the first lens (10) and the spacer (16) have a common axis. The second lens is then rotated about the center of curvature of the second surface (C3) of the spacer until all three have a common axis (15). Additional lenses and spacers can be added in a similar manner to build up the assembly.
