  • Patent number: 6360890
    Abstract: A storage book for holding a plurality of discs, other substantially-flat objects, or combinations of discs and objects, such as CDs, DVDs, computer diskettes, photographs, or the like, and having front and back covers interconnected by a spine member and movable between a closed position, in which the covers are generally stacked in parallel disposition to one another, and an open position, in which the covers are generally co-planar, and having a spacer attached to one of the covers, and further having at least two adjacent disc holders each pivotally mounted at a fixed location on the spacer such that the disc holders are movable between a folded position, in which the disc holders fully overlap in stacked relation when the covers are in closed or opened position, and an unfolded position, in which the disc holders partially overlap in staggered relation to one another when the covers are in open position.

  • Patent number: 6186690
    Abstract: An improved strap connection system for releasably binding pages together within covers in a lay flat condition including a pair of cover pieces and a strap having one end anchored to one cover piece, the other end extending away from the cover piece and an arrangement for releasably securing the extending end of the strap to the other cover piece. In a preferred embodiment, the improved strap connection system is utilized in an album including a front album cover, a rear album cover and a pair of flexible strap members with one end fixedly secured to the rear cover and with the other end extending away from the rear cover. The arrangement for releasably securing the extending ends of the strap members preferably comprises a retaining sheet attached to and forming a pocket with the front cover and the extending ends may include a textured surface for frictionally retaining the ends within the pocket.

  • Patent number: 4855046
    Abstract: Disclosed is a simple, economical ion exchange system for cleaning water, particularly rinse water from plating operations. Two or more identical cannisters with clear plastic sidewalls are connected in series and each contains resin in a central zone for removing anions or cations from water pumped from a reservoir through the cannisters. The resin material is held between permeable separator plates which also define inlet and outlet plenums accessible through openings in the sidewall near opposite ends of each cannister. The identical cannisters are stackable in one or more vertical arrays containing any suitable number of cannisters. Standard screw-type pipe fittings connect the inlet and outlet of successive cannisters to facilitate rapid disassembly of a multi-cannister ion exchange system and removal/replacement of cannisters whose resin requires regeneration.

  • Patent number: 4783249
    Abstract: The continuous flow of fresh water to and metal hydroxide contaminated water from a counter flow rinse tank in an electroplating apparatus is greatly reduced or eliminated by a parallel flow path provided to an adjacent ion exchange treatment unit and from the ion exchange unit back to the rinse tank. The rinse tank is fitted with a submerged pump to provide the rinse water to the ion exchange unit and through this unit back to the rinse tank.

  • Patent number: 4501650
    Abstract: In a plating machine the circuit board workpieces are held in clamp assemblies which grip the leading edge of each board so that the lower edges of the boards can be plated as the clamps travel around the machine. These clamps are adjustably mounted on a chain, and can be quickly removed for varying the spacing between them. Each clamp is designed to be loaded by the machine operator in a one handed operation without any separate clamp opening motion by him.

  • Patent number: 4394241
    Abstract: An overhead monorail transports racks, in which individual generally flat planar workpieces are suspended, along a path which may provide for several discrete processes in the production line of the circuit boards, and which path includes horizontal linear portion defined in a receptacle adapted to contain an electrolytic solution through which solution the racks and workpieces move between opposed insoluble electrode grills. A pressure manifold is provided at the bottom of the electroplating tank and upstanding nozzle defining towers are adapted to spray electrolyte from immediately behind the above mentioned insoluble electrode grills to continuously impinge upon the surfaces of the circuit board as the boards pass downstream through the tank. Metal to be plated is stored in receptacles behind the pressure manifold nozzle defining towers and the workpiece racks and anode baskets are coupled to a primary source of electrical power such as a rectifier.

  • Patent number: 4377461
    Abstract: The tab plater has holders mounted on trolleys to move planar workpieces through plating heads designed to treat and to plate the lower marginal edges. Each holder includes a vertically oriented work arm and an adjustable bracket which is adapted to clamp the upper edge of each workpiece. Each plating head has a chamber which includes insoluble anode means and nozzle openings communicating with plenum chambers containing electrolyte fluid under pressure to spray the workpieces as they move through the plating head.

  • Patent number: 4268206
    Abstract: An automatic electroplating machine has a plurality of plating barrels supported by cantilever arms on an elevator-conveyor for intermittent movement along a continuous, generally horizontal path to and through a plurality of work stations. Groups of barrels are lowered into and lifted out of a series of treating tanks located at work stations and along a rectilinear portion of the conveyor path. When the barrels are in lowered positions pinions on some of the barrels are engaged with reciprocally movable rack assemblies which oscillate the barrels in unison about horizontal axes and within the associated treating tanks.
