Abstract: ABSTRACT            A method is disclosed for eliminating so-called halo blocked apertures in color picture tubes.          Such tubes comprise an evacuated envelope having therein a luminescent viewing screen, an electron gun for producing at least one electron beam for exciting the screen to luminescence,and an apertured mask closely spaced from the screen for selectively intercepting and transmitting portions of the electron beam.  A getter is provided for coating an interior surface of the apertured mask with a gas-sorbing, conductive getter material film.          The halo blocked apertures are caused by insulative negatively-charged particles attached to the interior surface of the apertured mask.  The conventional tube processing includes the steps of getter flashing, cathode discharge ball gap, cathode conversion, hot shot, first low voltage age,initial testing,implosion proofing,external coating,frit breakdown check,radio frequency spot knock and final low voltage age.The method of the invention comprises controlling the getter flashing step so that the getter yields a primary film having about 50 to 75 percent of the available getter material.  The getter is reactivated, subsequent  to the frit breakdown check step and before the final low voltage age step,to provide a secondary film of getter material on the interior surface of the mask which will render conductive the insulative particles attached to the interior surface of the apertured mask.

Abstract: TUFTED ANGULAR BRUSH CONSTRUCTION              Abstract of the Disclosure A tufted brush construction comprises a thermo-plastic sheet substrate having a curved configuration and a plurality of mutually-spaced synthetic filament tufts mounted on the substrate.  Each of the tufts has an end fused integrally with the substrate and extends outwardly at an angle different from the angle of each adjacent tuft.  Preferrably each tuft extends outwardly from the substrate substantially perpendicular to the portion of the surface of the substrate mounting that tuft.  Thus, the tufts may diverge from a convex-shaped substrate to form a flared brush construction, or converge from a concave-shaped support.  Usually a handle is pro-vided for supporting the tufted brush construction.

Abstract: ABSTRACT          A condensate drain has a valve seat (4), a closure element (5) on the inlet pressure side, and at least one bimetallic snap-action disc (6,14) on the inlet pressure side.  The closure element (5) is mounted upon the bimetallic disc (6) in such a manner as to have relative axial movement.  The valve seat (4) is located within the lifting range (a4 - a8) of the bimetallic disc, wherein the force thereof acts, during the snap closing stroke, in the closing direction.  An at all times abrupt increase and decrease in the sealing force at the closure element (5) is obtained, thus preventing erosion and the deposition of dirt at the shut-off location (4,5).

Abstract: TREE AND BRUSHWOOD HARVESTER            ABSTRACT        A machine for clearing and cleanly chipping trees and brushwood in the path of the machine as it moves forward. A pair of counterrotating disk cutters cut a kerf in the standing material and propel the cut material upwardly and rearwardly to the throat between a pair of feed rollers. The feed rollers deliver the cut material to a chipper, which reduces the material to chips and delivers them to a chip storage bin. The bin can be tilted to dump chips alongside the machine. The entire mechanism is carried by a self-propelled, articulated, track-supported vehicle which is especially well-suited for operation over soft, boggy ground.

Abstract: ABSTRACT    A solar ray collection apparatus includes a plurality of lenses mounted on at least one of opposite surfaces of a lens mount.  A plurality of light conducting members equal in number to the lenses are carried by a conductor mount which is held integral with and spaced from the lens mount by spacers and a frame, so that the focal point of each lens may coincide with the adjacent end of its associated light conductor.  The lenses, lens mount, conductor mount, spacers and frame are made of materials the coefficient of expansion of which are equal to or substantially equal to each other, thereby overcoming the influence of the solar heat.  Positioning means may be employed which moves the end of each light conducting member into alignment with the center of the adjacent lens, and then to the focal point of the lens and then fixes it in position.  Stray beams in the apparatus may be converted into electrical energy at a suitable position or positions in the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE           In a magnetic reproducing apparatus for reproducing a luminance signal and timebase-compressed chrominance component signals recorded on separate tracks of a record medium, the reproduced chrominance component  signals are directly supplied to a timebase expander and this timebase expander uses a reference clock which reference clock is employed in the timebase correction of the luminance signal and frequency-divided by the timebase compression ratio whereby to perform the timebase expansion and the timebase correction at the same time.  Thus, it is not necessary that the timebase correction and the timebase expansion are performed by separate circuits and this leads to a simple circuit arrangement.

Abstract: ABSTRACT OF THE DISCLOSURE   A coupon is bonded to a component using a bonding agent which is capable of withstanding temperatures only up to a selected temperature above which the bonding agent no longer holds the coupon to the component. The component, during an operation, is intended for exposure to temperatures not above the selected temperature. An exposure of the component to the elevated selected temperature is identified by the fact that the coupon is no longer bonded to the component after termination of the operation. When the component is provided with insulation, the selected temperature is chosen to correspond to a temperature at which the insulation fails to determine the integrity of the insulation after the insulation. The coupon may be bonded to anexterior or interior surface of the component. With an exterior bonded component, visual inspection is sufficient. With an interior bonded component, detection means such as ultrasonic instrumentation is utilized to determine the presence or absence of the bonded component.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for both improving the heat distribution throughout a room from a portable kerosene heater and for collecting undesirable emissions resulting from the burning of the kerosene, includes a base adapted to be mounted on the top of the heater, the base supporting a vertically extending shaft on which is mounted a heat-driven fan formed of either paper or metal, and a disposable disk mounted a spaced distance above the fan on the same shaft, the disk serving as a collector for the undesirable emissions.  When the device is placed on an operating kerosene heater, the rising hot air and gases from the heater cause the fan to rotate, which in turn causes emissions from the burning fuel to move upwardly in a more or less cylindrical path.  As the products of combustion move upwardly, certain emissions therein such as soot, oily vapors, etc. deposit or condense onto the surface of the spinner and disposable disk.

Abstract: ABSTRACT         Electrostatic sheet feed including a translatable member having a generally planar surface formed of an electrically insulative material is disposed closely proximate to or even in contact with either the top or the bottom of a sheet stack.  A pair of electrodes in the form of an electronic grid is secured to the planar surface.  A DC voltage is applied to the electrodes selectively to effect a highly intense electric field only close to said surface.  The intensity of the electric field can be varied in predetermined relation to the applied DC voltage so as to determine the number of sheets simultaneously removed from the stack.  The electric field exerts an attractive force only on the upper-most sheet of sheets of the stack to enable stripping of only said upper-most sheet from the stack.

One of the bearings is located inside the spindle so that the bearing mountings for the rotor shaft can be spaced as far apart as possible, thus reducing the amount of wow and flutter even though the player is extremely compact.  The spindle mounting the motor shaft is driver. independently of the motor by a drive gear which engages the periphery of a gear wheel secured to the spindle.          The drive gear is driven by a drive belt which extends from the motor rotor to the player capstan.
