  • Patent number: 4961956
    Abstract: Electroluminescent phosphors, electroluminescent panels and lamps made with such phosphors, and a process and apparatus for treating phosphors are disclosed in which the phosphor particles are coated with a very thin coating of SiO.sub.2, to protect the phosphor particles from aging due to moisture intrusion. The phosphor particles are coated in a cold wall reactor by the pyrolytic decomposition of silane in the presence of heat and oxygen to a coating thickness of approximatley between 0.1 and 3.0 microns. The apparatus and method of coating includes the placement of a quantity of phosphor in a cup-shaped heated reactor bowl and subjecting the particles to a temperature of about 490.degree. C. and an atmosphere of silane and oxygen, while continuously mechanically agitating the particles with a blade arrangement in which the particles are continuously rotated and turned so as to expose the surfaces of the heated particles to the reaction atmosphere.

  • Patent number: 4960259
    Abstract: A shut-off valve for a fluid flow or an infusion instrument is described. A sleeve-form casing (2) with a lateral opening (4) between its ends is provided. An elastic tube piece (7) lies within casing (2) to allow fluid flow therethrough. A pressure body (14) is movable radially within the lateral opening (4) to selectively compress or not compress the tube piece (7) so as to occlude or open fluid flow through the tube piece (7). For simplification of manufacture and for quick operation of such a shut-off valve, especially without painful or injurious activities in operation, a tubular guide sleeve (8) is provided and surrounds the lateral opening (4) of the casing. Sleeve (8) is arranged to laterally project from the casing (2) and includes at least one pair of blocking stops (10, 10', 11 11'). The pressure body (14) has a plug shape. On the end of the pressure body (14), facing away from the tube piece (7), there is fastened a cap (16) with an elastic mantle (12) and snap ring (18) depending from the cap.

  • Patent number: 4953759
    Abstract: A metering valve assembly for dispensing measured quantities of an aerosol from a pressurized container comprises a housing constructed for sealed attachment to a pressurized container and having therein a partition wall of resilient material enclosing a metering chamber. An operating member is supported in the housing for movement between charging and dispensing petitions. In the charging position of the operating member, a charging connection is established between the interior of the pressurized container and the interior of the metering chamber to fill the chamber with a pressurized charge. In the dispensing position of the operating member, the metering chamber is shut off from the interior of the container and connected to a dispensing outlet, whereupon the pressure within the container will collapse the resilient partition wall and thereby force the contents of the metering chamber to the dispensing outlet.

  • Patent number: 4954297
    Abstract: A glosser, and method of glossing, includes a belt-type glosser in which resin-coated web or sheet material is pressed or molded against a casting surface of the belt under heat and pressure, and is thereafter removed. A matte surface is provided by forming a non-locking grooved pattern on the casting surface of the belt in the form of a diffraction grating. The grating configuration is formed with a series of lands, separated by grooves or depressions, in which the side walls of the depressions are tapered to provide a valley narrower at the bottom than at the top adjacent the land surfaces so as to be free of resin-trapping overhanging projections or portions. The spacing between the grooves may be randomized.

  • Patent number: 4952134
    Abstract: Apparatus for forming a self-standing skirt on the pressure bottom of a blow-molded carbonate beverage container. The preform is formed with an annular depending skirt, and the skirt is stretched with a stretch mechanism which engages all but a lower portion of the preform, so that during the stretching of the preform concurrently with the blowing of the preform in a bottle mold, the lower portion folds inwardly to form a bottom ledge on the stretched skirt. The mold is provided with a centering mechanism for assuring the centering of the preform within the mold cavity to assure that the preform skirt receives the skirt stretching mechanism.

  • Patent number: 4951701
    Abstract: A combined air vent and overpressure relief valve for a submersible pump includes a single tubular housing to be inserted in an opening in the upper end wall of a chamber on the outlet pressure side of the pump. The upper end of this housing has a vent hole therethrough, and inside the housing is an annular valve seat facing upwardly. A valve disk within the housing is proportioned to move lengthwise thereof toward and away from the valve seat but is normally biased into sealing engagement with the seat by a spring within the housing. This valve disk has a bleed hole therethrough, and a valve ball is caged in the lower part of the housing, below the valve seat for movement into and out of sealing engagement with the lower end of the bleed hole in the valve disk as the pressure within the chamber rises and falls.

  • Patent number: 4947685
    Abstract: A method and apparatus for measuring the repeat length (L) of a moving web includes forming a plurality of detectable marks along the length of the web at a repeated length interval. First and second detectors positioned along the web path are separated by a known distance (S). The repeat length of the web is obtained by detecting a mark moving past the first detector and then detecting a mark moving past the second detector, determining the time (t) separating the detections, and measuring the speed of the moving web (V), wherein the repeat length is calculated using the formula L=S+Vt.

  • Patent number: 4948467
    Abstract: An extended nip press for papermaking machine extracts water from a web of paper on a forming felt passing over a backing roll employing electromagnetic repulsion forces. In one embodiment, a belt is formed with permanent magnets which have thickness oriented poles and a like pole is provided external to the belt surface in non-contacting relation to provide a repulsion force to the belt which is transmitted by the belt to the felt and the paper. In another embodiment, the belt is formed of current-carrying nonferrous material and a repulsion force is formed by inducing current to flow in the belt by causing current to flow in an adjacent coil in non-contacting relation to the belt. In either embodiment, air pressure housing may be positioned over the electromagnet or conductor, to cool the electromagnet and to apply an air pressure force against the belt in the same direction as that of the induced or repulsion force.

  • Patent number: 4946405
    Abstract: An improved solderless electrical terminal connector includes a plurality of serrations or notches formed on its lower surface for improving the electrical and thermal contact between the connector and the surface onto which it is mounted. The wire receiving portion of the connector includes a set screw for holding the wire securely in place in a body member. The cross-sectional area of the body member in the direction of the wire is reduced so that it is less than the diameter of the set screw thereby to improve pullout characteristics. The opening for the wire in the body member extends into a tang to form a stop to provide for ease of installation of the wire. This placement of the wire will also reduce electrical resistance. In an alternate embodiment, a spiral groove may be formed in the wire receiving opening to cut into the wire as it is clamped in place both to improve pullout characteristics and to lower the electrical resistance between the wire and the connector.
