Abstract: FIBER OPTIC CATHODE RAY TUBE CAMERA                    ABSTRACT OF THE DISCLOSURE         A cathode ray tube is coated on the inside of its fiber optic front plate with a broad band phosphor.  In front of the front plate a second fiber optic plate is located.  Three parallel strips of dichroic color filters are vapor deposited on the inside of the second plate.  Optical contact between the two optical fiber plates is established by a layer of immersion oil. A photosensitive material is moved at a slight distance along the second fiber optic plate transversely to the color filter strips so that it will be exposed line by line.  The use of filters in place of different phosphors to produce the individual colors produces significantly improved color separation and thus better reproduction of the image, while retaining the inherent advantages of fiber optic plates.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for cutting parts out of a sheet of material including a cutting table, an endless gas permeable conveyor movable in a feed direction along the cutting table for supporting the sheet material thereon, a suction box for applying a vacuum to the conveyor and holding the material firmly against the conveyor during a feeding step and a cutting step, a plasma arc cutter for cutting parts from the material supported on the conveyor and a carriage for supporting the plasma arc cutter and moving it along pattern coordinates of the parts.  A brake is mounted on the carriage for selectively engaging the conveyor with the carriage to thereby selectively advance the conveyor along the feed direction.  A controller stores pattern coordinates of the parts and controls movement of the carriage and actuation of the brake.  The carriage is controlled by the controller to move a distance in a feed direction which is greater than the length of the feed direction of the longest part to be cut from the sheet material during a cutting step.  Also, the controller actuates the brake to release engagement between the carriage and the conveyor so that the carriage can be controlled by the controller to move the plasma arc cutter along pattern coordinates of the parts.  The apparatus also includes labelling and pickup apparatus located downstream from a cutting zone on the cutting table.

Abstract: ABSTRACT OF THE DISCLOSURE    The  flow of  molten metals,  for  example,  molten steel, from one location to another, typically from the ladle to the tundish and from the tundish to a casting machine  of  a  steel  continuous  casting procedure,  is controlled by the application of a magnetic field to the metal.  A magnetic field-producing device surrounds a tube conveying the molten metal between two locations.          The magnetic field produces a restriction in the molten metal by interaction with eddy currents induced in the molten  metal.    The   restriction   is   of   variable cross-sectional dimension, depending on the strength of the magnetic field, and thereby controls the flow rate of the molten metal.

Abstract: MICROWAVE DIRECTIONAL FILTER             WITH QUASI-ELLIPTIC RESPONSE            ABSTRACT OF THE DISCLOSURE      Circularly polarized radiation is tapped off from an input waveguide through an input iris into an entry cavity, where it is resolved into two orthogonal linearly polarized components.  These respectively proceed along two discrete paths to an exit cavity.          In each path six independently tunable resonances --traversed by both direct and bridge couplings --provide enough degrees of freedom for quasi-elliptic filter functions.  In the exit cavity the resultants from the two paths are combined to resynthesize circularly-polarized radiation, which traverses another iris to the output waveguide.    In one layout, four resonant tri-mode cavities form a rectangular array -- with entry and exit cavities at diagonally opposite corners and intermediate cavities for the two discrete paths in the two remaining corners. In another layout, six dual-mode cavities form a three-dimensional array: entry and exit cavities stacked one above the other, and two intermediate two-cavity stacks for the two discrete paths adjacent the entry/exit stack.

Abstract: ABSTRACT OF THE DISCLOSURE     A drill bit having thermally stable PCD cutting elements includes a matrix body element having a plurality of spaced cutting elements supported in a body of matrix material such that a substantial portion of the cutter is above the body matrix and a minor portion is received within the body matrix. The cutters have side surfaces exposed and are so positioned that at least in some of the cutters more surface area of one side face is exposed as compared to the other side faces. The cutter support may include a small pad of matrix material to reduce the loading directly on the PCD. In a preferred form the PCD elements are mounted on pads or blades formed by spaced channels. The hydraulics are straight radial flow and improved hydraulic flow is achieved through the use of waterways which concentrate the fluid flow near the face of the cutters. In one form, improved hydraulics are obtained by having one fluid discharge port for each of the radially disposed fluid channels. Various forms and arrangements are disclosed.

Abstract: A method for preventing corrosion of an expandable mounting element which involves introducing a sealing composition into a mounting hole of a support structure first to fill the hole about half-way, then driving an expandable mounting element into the half-filled hole to displace the sealing composition initially against the base of the mounting hole and then up along the surface of the expandable mounting element until the excess emerges out of the mounting hole. A compressible impact device, which has an upper and lower part and a spring part fixed therebetween, is arranged so that an impact tool can be driven against the upper part to fully drive the expandable mounting element into the mounting hole, effecting a sealing compaction in correspondance with the pressure exerted by the spring part. All gaps and cracks are thereby sealed against corrosive media.
