  • Patent number: 6152032
    Abstract: A mist containment system including shieldings (6, 7) assigned to a rotating surface (2). Gaps (4, 5) are created between the shielding (6, 7) and the rotating surface (2). Mist contained within the shieldings (6, 7) is kept within the shielding (6, 7) and prevented from escaping through the gaps (4, 5) either by a negative pressure differential device creating a negative pressure differential across the gaps (4, 5) or in alternative by a condensation device (17) condensing solution which is collected by gravity or by electrostatic charging the spray particles contained in the mist as well as the rotating surface (2).

  • Patent number: 6119591
    Abstract: A processing method for undetachably printing pictures on the surface of a fastening sheath for a shoe lace head, including the steps of: processing acetic acid fiber at high temperature and then pressing the fiber into transparent film which is wound into a roll of film; printing one side of the film with necessary colorful pictures by general ink printing technique; printing two liquid transparent inks onto the side of the film to cover the colorful pictures as a protective coating for protecting the colorful pictures from being corroded by chemical adhesive agents; and by means of a fixed mold and a movable mold, which are unifiedly operated at a certain temperature, placing the head section of the shoe lace on the fixed mold and spraying chemical adhesive agents such as MEK, acetone, toluene, etc. thereon. The roll of film is then cut off into a segment of film having a certain length with the necessary colorful pictures.

  • Patent number: 6109719
    Abstract: The invention described in the specification relates to an apparatus and method for cooling a printhead containing multiple semiconductor substrates. The substrates which contain a plurality of energy imparting devices for energizing ink are attached to a metal substrate carrier for providing efficient heat transfer from the substrates. A temperature sensing device is attached to the carrier for measuring a temperature of the substrate carrier during a printing operation and for generating an input signal to a controller. The controller, in turn, sends an output signal to the printhead to selectively energize one or more of the energy imparting devices on each substrate in response to the input signal and a thermal expansion value based on the temperature of the heat transfer member. Because the timing of energization of the energy imparting devices is controlled in response to the carrier temperature and its expansion characteristics, more cost effective materials for the carrier can be used.

  • Patent number: 6095088
    Abstract: A pet litter box assembly is provided having an open-ended base into which litter can be placed, a cover which can be latched upon the base in order to seal the base and a waste collecting member mounted within the cover at a position spaced from the underside of the cover. When waste and used litter deposited in the base needs to be separated from non-used litter placed in the base, the cover can be seated upon and latched to the base and the pet litter box assembly can be rotated to cause the contents of the base to flow onto the waste collecting member. The waste collecting member includes numerous filtering orifices that are sized to permit non-used litter granules to readily flow therethrough while waste and used litter is collected in the waste collecting member for disposal. The base and the cover have double-wall constructions and therefore each includes inner and outer wall portions.

  • Patent number: 6067904
    Abstract: An inking-pad printing press has at least one container (1) for inking a printing plate and a press device for pressing the container against the printing plate. The printing plate (2) and the container are moved in a mutually reciprocating manner by a drive mechanism in order to ink a printing block of the printing plate. During the inking process, the position of the container relative to the longitudinal axis of the printing block and hence to the printed image is varied by a further relative movement. This further relative movement is, for example, an oscillating, rolling, swaying, swinging or thrusting movement.

  • Patent number: 6065885
    Abstract: An improved reusable media carrier having positive alignment capability and improved carrying characteristics for advancing one or more pieces of printable card stock media or the like through a computer printer, word processing printer, or copy machine. Such means is in the form of a flexible rectangularly configured carrier, particularly suited for use with printers or copy machines having friction, sheet-feed mechanisms. The carrier is comprised of an essentially rectangular sheet of paper or other flexible material folded in such a way as to provide retainers for positively engaging at least two adjacent side edges of a piece of media to be printed. In addition, the retainer means may include hard stops for effecting positive media alignment and location. Furthermore, the carrier may include embedded strips of stiffener material for minimizing curl of the media carrier.

  • Patent number: 6065399
    Abstract: A screen off contact arrangement in which a rectangular screen holding frame [11] is adapted to secure the screen [13] on its two side rails [17,18]. Four off contact devices at the corners of the frame [11] allow adjustment of the off contact distance between the screen and the pallet. A scaled knob [33] enables incremental movement of the shaft [29] to move it relative to the fixed front and rear rails [15,16]. Each shaft [29] is secured to the ends of the side rails [17,18] so that incremental movement of the knob [33] results in movement of the screen [13]. The advantage is a simple repeatable manual adjustment.
