Abstract: ABSTRACT This invention relates to a reliable and simple loading mechanism for a video tape recorder which makes it possible to rewind a loaded tape into a cassette without having to greatly force it.  The mechanism employs a plunger activated by a play back or video recording button which slides a slide plate, an idler, a gear mechanism which draws a tape from the cassette through at least a pinch roller which contacts a capstan, and a stop button which restores the pinch roller toward the cassette in order to change it over to unloading.  A swingable plate at the gear mechanism operates when changed over to unloading, and a swingable board operates with a pin formed at the swingable plate to restrain the slide plate from restoring.  This allows the drawn-out tape to be wound into the cassette through the take-up reel when the pinch roller is restored toward the cassette.

Abstract: ABSTRACT OF THE DISCLOSURE           An illustrative embodiment of the invention provides a valve seat that has hot, cold and discharge water apertures.          A plate, relatively rotatable with respect to the valve seat, is pressed against the valve seat surface.  A cavity formed in the plate adjacent to the surface in contact has a pair of axisymmetric lobes which are asymmetric with respect to an axis that is perpendicular to the axis of symmetry,  This configuration permits cold water flow first through the valve with counterclockwise motion of the plate in spite of the relative sources of hot- and cold-water through simple inversion of the plate, as appropriate.  Hot and cold-water pressure loss and surge protection, moreover, is provided through a pressure balancing valve.

Abstract: MUD DEGASSER PUMP     Abstract of the Disclosure.  Gas laden drilling mud is effectively handled by a centrifugal pump system which allows the flow of released gases from the drilling mud to move in the same axial direction as the mud flow through the pump; whereupon the re-leased gases may be conducted to safe disposal areas.  A hollow-centered impeller is driven by a hollow shaft through which the gases may be withdrawn.  A prerotation chamber and impeller shroud below the impeller admit drilling mud into the impeller housing, providing the drilling mud with initial rotational velocity through a reduced radius, and further establishing a central opening through which gases escaping from the drilling mud will be released due to centrifugal forces on the mud.  Released gases may then be removed through the central passage in the hollow shaft, which shaft may be provided with external means for preventing upward flow of fluid therearound. la

Abstract: ABSTRACT          An electrode for use in an electrolytic process is provided with a mixed oxide interface between a titanium base and an outer coating. The mixed oxide is formed at said interface by means of titanium from the base and noble metal from a solution containing a predetermined amount of HCl which attacks the titanium base surface. Slow drying provides a metal chloride mixture which is thermally converted to said mixed oxide of titanium and noble metal in a given ratio, whereby to protect the titanium base from oxidation, An outer coating of manganese dioxide or lead dioxide is electroplated on the mixed oxide layer so as to provide an inexpensive electrode with improved resistance to oxidation.         This electrode can be used for various processes where a high resistance to oxidation is required, e.g. as a manganese dioxide anode in a metal electrowinning process or as a lead dioxide anode for electroflotation ox organic oxidation reactions.

Abstract: SEISMIC PROSPECTING USING A CONTINUOUS SHOOTING         AND CONTINUOUS RECORDING SYSTEM            ABSTRACT      A method of seismic prospecting is disclosed wherein the seismic source (14) is excited in such a manner as to maximize the use of the energy (24) generated thereby.  In certain cases it may be desirable to convert the received seismic signals to their frequency domain counterparts before performing subsequent processing.          Such conversion may be performed using the discrete Fourier transform with the result that transformed values are obtained only at certain discrete frequencies.  It may further be desirable that processing be performed only at subsets of the total set of discrete frequencies with the values at the remaining frequencies being discarded.  In the practice of the present invention, source energy is generated only at those discrete frequencies at which subsequent processing is to be performed.  As a result there is substantially no source energy in the transform values at the frequencies which are discarded.

Abstract: A B S T R A C T   A printed circuit board, and method for its fabrication, wherein a first side of the board includes a network of interconnection wires channeled generally in groups along pathways apart from the region for the installation of electrical components and the board apertures through which their associated leads pass. The network of wires is encapsulated below a plastic sheet adhered to the surface of the circuit board after wiring. The electrical components are subsequently installed from the same side as the network of wiring and are electrically connected into the wiring network by wave soldering applied to the opposite board surface. Such a printed circuit board permits the doubly efficient use of automated interconnect wiring in combination with component installation by wave soldering. The network of wiring is typically adhered to the surface by a layer of sheet adhesive applied under elevated temperature and pressure. The adhering of the Interconnect network keeps individual wires from interfering with the installation of circuit components and makes possible the location of both components and interconnect wiring on the same circuit board side. This in turn frees the opposite side for mass installation techniques such as wave soldering.
