  • Patent number: 6409308
    Abstract: A method of forming one or more nozzles in a substrate used, for example, as a nozzle plate in an inkjet printhead of a thermal inkjet printer, using laser ablation, An opaque mask is interposed between a source of a laser beam and the substrate and includes one or more transparent, ring-shaped orifices therethrough arranged in a closely-spaced matrix. The beam is emitted from the laser source towards the mask such that the opaque portions of the mask block the beam from passing through the mask except for through the ring-shaped orifices. The beam is thereby separated into one or more ring-shaped beam portions, each of which penetrates the substrate at approximately the same and substantially constant intensity to ablate one or more ring-shaped openings in the substrate arranged on the substrate as a closely-spaced matrix. Ring-spaced openings each defines a center plug portion, which is removed from the substrate, for example, by vacuum or adhesive.

  • Patent number: 6267472
    Abstract: A heater chip module is provided comprising a carrier adapted to be secured directly to an ink-filled container, at least one heater chip having a base coupled to the carrier, and at least one nozzle plate coupled to the heater chip. The carrier includes inner side walls and a support section which together define an inner cavity. An edge feed heater chip is coupled to the carrier support section. The heater chip includes side walls. The support section includes first and second passages which define first and second paths for ink to travel from the container to the inner cavity. The inner cavity and the heater chip are sized such that a first side wall of the heater chip is spaced from a first inner side wall of the carrier and a second side wall of the heater chip is spaced from a second inner side wall of the carrier. A nozzle plate is coupled to the heater chip and the carrier. The nozzle plate has a width such that the nozzle plate extends over an outer surface of the carrier.

  • Patent number: 6260723
    Abstract: A package for flowable media and a snap lid which package and snap lid are both made from thermoplastic material, in which a collar-shaped head of the package surrounds a pouring aperture of the package, which collar-shaped head has a retaining ring on its outside, an inside annular surface, and an upper end having an edge with a snap catch, which upper end can be closed using the snap lid. The snap lid has a closing wall from which an annular sealing lip projects towards an inside of the package, and can be brought into contact with an inside surface of the edge in sealing engagement. The closing wall is provided with an outside catch for snap engagement with a snap catch of the edge of the head. The head of the package widens outwards and upwards at its edge, and both the inner surface of this edge and an outer surface of the sealing lip on the snap lid are curved convexly relative to each other. The invention also includes preforms for making the package of the invention.

  • Patent number: 5862912
    Abstract: A package (10, 100) of building-panel products consists essentially of panels (20), panel accessories (30, 32a-d, 110a-d, 120), and at least one binding means (80, 70a, 70b), which may include strapping and/or clamping elements. The panels, which are to be mounted to a structure such as a house, are arranged in a stack (20a). The accessories, which are to be mounted to the structure in association with the building panels, are positioned to frame one or more sides of the panel stack so as to help maintain the panels in stacked relationship. The binding elements releasably secure the accessories to the stack of building panels to form a cartonless package.

  • Patent number: 5849131
    Abstract: Our unique process applies pressure sensitive hot melt adhesive to fiberglass insulation with improved adhesion to the insulation surface and the adjoining substrate. As opposed to the typical spray or bead extrusion methods, the preferred embodiment applies a ribbon of adhesive to the blanket and pulls it into the insulating glass with a vacuum. The adhesive penetrates the glass and becomes an integral part of the insulating blanket.

  • Patent number: 5797513
    Abstract: An insulated vessel (10, 100, 130) is provided which is adapted to receive a low or high temperature material to be insulated from the environment. The vessel comprises inner and outer membranes (20, 110, 140) and (30, 120, 150) and an outer casing (40, 170). The inner membrane defines an inner cavity for receiving the low or high temperature material and has a first portion which defines an entrance into the inner membrane. The outer membrane encases the inner membrane such that a space is defined between the inner and outer membranes. The outer membrane includes a second portion which is positioned adjacent to the first portion. An insulating material (60, 160) is located in the space between the inner and outer membranes. The inner and outer membranes are joined together so as to seal off the space from the environment. The space is evacuated to less than atmospheric pressure. The outer casing surrounds the outer membrane and has sufficient strength to provide structural and abuse integrity to the vessel.
