Abstract: ABSTRACT            A printing method and apparatus for imprinting a composite multi-colored image on a substrate.  The apparatus has multiple independent stations having a master sleeve with an image in semipermanent fixed primary dielectric toner formed thereon.  The image is transferred directly or by way of an intermediate transfer roll.  The master sleeve is charged in light, the toned parts retaining charge.  The resulting now charged image is toned with a pigmented secondary toner and this double toned image is pressed against the passing substrate or brought very close to it either directly or through the transfer medium.  An electrical field is established between the substrate and the sleeve or transfer medium, the toner transferred to the substrate and the sleeve or transfer medium circulate back to pass through the same process of charge, tone and transfer.  The transferred images are fixed between or during movement through the stations.  Image density information can be used to control change in the electrical field conditions or other parameters.  The impressions from each station are applied in registration.

Abstract: MICROPROCESSOR TEST SYSTEM             ABSTRACT OF THE DISCLOSURE           Apparatus and method for testing the operability of a microprocessor and a machine controlled by the micro-processor are described.  The input/output ports of the microprocessor are tested by propagating, via a test program in the microprocessor, a test logic level along the ports of the microprocessor.  As the test logic level propagates, its position is revealed by the successive energization of adja-cent light-emissive devices which are external to the micro-processor but connected to the microprocessor ports.  Proper propagation of the test logic level is indicated by a cor-responding propagation of light across the light-emissive devices.  To test the machine, the microprocessor is put in a quiescent but energized state and test logic levels are applied to the ports coupling data between the microprocessor and the machine.  Selected functions of the machine are thus exercised independently of the microprocessor.

Abstract: PROCESS FOR HYDROPHILIZATION OF METAL SURFACES AND/OR METAL OXIDE SURFACES               ABSTRACT OF THE DISCLOSURE          This relates to the hydrophilization of metal surfaces and/or metal oxide surfaces.  In the forming of sheet metal by drawing and wall ironing methods, in the past it has been necessary to provide lubricants so as to not only protect the metal, but also to hold down friction noises.  The lubricants are difficult to remove and require expensive washing processes after the forming operation. It has been found that an hydroxide of the metal involved may be readily generated on the surface so that the surface is easily wetted by water, for example, and thereby conven-tional lubricants are eliminated.                     * * * * * * *

The roving and the randomly mixed sliver are twisted together so that the sliver wraps around the roving in order to form a double layered roving.          After the double layered roving is subjected to fine spinning, it is then subjected to a heat treatment.  As a result, a multi-layered bulky spun yarn is obtained.

Abstract: REINFORCING STEEL FOR CONCRETE          ABSTRACT OF THE DISCLOSURE    The invention relates to weldable concrete reinforcing steel and a method of forming such steel.  In this steel there is a central zone consisting of a perlite-ferrite mixture and a surface zone of annealed martensite.  There is no intermediate layer or layers between the central zone and the surface zone.  The steel is formed by a special cooling treatment in which transformation to bainite is avoided.  The steel is advantageous because it is inexpensive to manufacture but is suitable for welding without loss of its advantageous characteristics.          The steel can also be manufactured into ribbed rods also without loss of advantageous characteristics.

Abstract: Abstract of the Disclosure In a turbine set with an axial flow which is traversed by water and which is coupled to a generator feeding a network of constant frequency, the flow turbine is a propeller turbine with non-adjustable blades.  The stator winding of the generator is connected to the network by means of a frequency-controllable converter, in particular a direct converter.  The speed of rotation of the turbine set is controllable continuously according to the power to be delivered.  In the case of an asynchronous design of the generator, it is advis-able to provide the stator with a waterproof jacket on the inside and to flange it into the turbine tube, since the rotor with its cage winding is swept by water.

Abstract: ABSTRACT Process For Beneficiating Oxidic Ores Low grade oxidic ores, such as, for example, chromite, tantalite, wolframite, ilmenite or bauxite may be beneficiated by chlorinating the ore in a fluidised bed in the presence of carbon to produce a gaseous effluent containing ferrous chloride, partially oxidising the ferrous chloride to a mixture of ferric oxide and iron chloride, condensing and then revolatilising the iron chloride, oxidising the revolatilised iron chloride to release chlorine and recycling the chlorine to the ore chlorination.  The process lends itself to efficiency of operation.  The ore may be preheated by the combustion of carbon utilising also the combustion of volatiles from the calcining of the carbon.  Preferably, sufficient carbon is present during the ore preheating to supply also the needs of the chlorination.  Preferably solid iron chloride is volatilised in the gaseous effluent from the chlorination. Iron oxide recovered may be used as a coolant in steel making.  The residual beneficiated ores may be used in the production of special steels or for other uses.      In a modification of the process values of metals other than iron such as, for example, values of boron, gallium, zirconium, thorium, titanium or uranium aluminium or silicon, may be removed from ore.

The edge is elongate and intended to wrap around an existing corner where two substantially planar surfaces intersect, one of the planar surfaces being a front surface and the other planar surface being a rearwardly receding flanking surface such as a top surface or a side surface of a vehicle.  The edge rises abruptly from the front plane and moves forwardly and outwardly in a convex arc to a point of abrupt inflection outside of the flanking plane and adjacent the front plane as extended through the flanking plane.  The discontinuity or inflection is a change from convexity to concavity formed by alternate concavity and convexity and progressing generally toward faired contact with the flank plane.

Abstract: APPARATUS AND METHOD FOR DETECTING     CROSSMODULATION DISTORTION                            ABSTRACT         A method and apparatus for detecting crossmodulation distortion on an optical sound track by detecting variations in the light transmitted through at least one predetermined area on the sound track, the predetermined areas being selected such that their transmittance varies substantially only with the amount of crossmodulation distortion on the sound track.  The predetermined areas preferably have dimen-sions along the sound track which are a whole number multiple of, and substantially greater than, the wavelength of a high frequency test signal.  Light is also transmitted through at least one second predetermined area on the sound track which clip the high frequency test signal, thereby providing a low frequency phase reference for determining the relative exposure of the film.  In an alternate embodiment, the predeter-mined areas are divided into primary and secondary areas, mutually spaced by a distance which is out-of-phase with respect to the wavelength of a low frequency test signal.          Crossmodulation distortion information is obtained by comparing the light transmitted through both areas.  Instead of single predetermined areas, multiple areas spaced by whole number multiples of the low frequency signal wavelength can he used to improve the resolution of the system's frequency response.          A mask with defined apertures controls the light paths.    Testing for crossmodulation distortion can he done by simply moving the film by hand a short distance through the test equipment.  Because crossmodulation is continously monitored, diagnostic testing is also possible.
