  • Patent number: 10618748
    Abstract: A packaging system and associated method for use with a pharmaceutical dispenser provides a turnkey solution for packaging pharmaceutical products such as solid medications and nutritional supplements to be taken orally in health care settings, including but not limited to long term care (LTC) and assisted living settings. An overall pharmacy system and methodology begins with bulk medications and supplements introduced into the work flow, individually packaged and assembled into medpass orders per patient and delivered to the LTC facility or other institution for patient consumption. The process begins by converting bulk medications and supplements to packaged unit doses and ultimately individually packaged medpass bags for each patient on a 24-hour schedule. The design of the overall system and its individual components allows for physical control of each unit dose package from start to finish without any unit dose package “free fall” in the system.

    Abstract: A modular air fluidized sand bed for the heat treatment of metal products is disclosed. This technology provides for the heat-treatment of steels, particularly long products, and other alloys and shapes using fluidized-sand heat transfer media. The technology directs gas burners into U-tube assemblies suspended in the media. The fluidizing agent is hot exhaust gas recovered from the U-tubes. Blended exhaust gases and cool air can maintain fluidizing gas, plenum and retort temperatures at nearly the same temperature as the sand. Constant volume and pressure of fluidizing gas maximizes heat transfer between sand and product. For extreme heating applications, a thermally insulated cover held in direct contact with the hot fluidized sand improves energy efficiency. A sand return system returns sand lost from the bed exit to entrance. The modular air fluidized sand bed includes a fluidization pressure and volume that are altered independent of a fluidization media temperature.

  • Patent number: 6770241
    Abstract: The invention is a device that is used to securely hold a crucible for lifting by a lifting device. It has a circular frame with a top bracing leg that ensures straight vertical lifting and proper alignment of the rigging. The frame diameter is slightly larger than the crucible. Vertical pieces extend downward from the top of the frame. At the bottom end of each of these vertical pieces, a hinged piece is attached. On the hinged pieces, a bottom rigging retainer is attached. The bottom rigging retainer allows the rigging to freely pass through it. The bottom rigging retainer with the hinged piece forms a loop through which the rigging is thread. The rigging securely holds the bottom of the crucible. A lifting device is attached to the riggings to lift the crucible. The frame can be made adjustable to fit many sizes of crucibles.

  • Patent number: 6669897
    Abstract: A method of treating a surface of a stacked aluminum alloy ingot during a heating process. Spacer blocks are positioned adjacent aluminum alloy ingots to form a stack, wherein the spacer block has a support surface contacting a contact surface of the aluminum alloy ingot, and at least one of the support surface and the contact surface include a fluorine containing material. The stack is heated to at least a temperature at which the fluorine containing material decomposes or vaporizes such that a layer of a fluorinated oxide compound is formed at the interfaces between the ingots and the spacer blocks.

  • Patent number: 6558615
    Abstract: An annealing basket made of steel, receiving mass-produced aluminium parts (20) for the degreasing and softening thereof, comprising a bottom and side by a frame. At least one side wall (16) is joined to the walls that protrude from said bottom and are defined frame (12) by means of at least one aluminium element (26) that can be plastically deformed when heated to an annealing temperature as a result of the pressure that is exerted on the side walls (16) and occurs in the annealing basket (10) due to thermal expansion of said aluminium parts (20), whereby the side wall (16) moves outwards to a certain degree under the effect of the increase in the volume of said basket in at least one area that is adjacent to the frame.

  • Patent number: 6505483
    Abstract: A pressure pad array is used to float glass sheets from a glass heating furnace to a ring mold in a press bending station. The pressure pads have transversely spaced, longitudinally-extending slotted nozzles angled towards one another to provide a static pressure area for floating the glass sheet. The slotted nozzles are aligned with the direction of glass sheet travel and the space between adjacent pressure pads is covered by a spacer baffle to generate additional static pressure flotation areas. The static pressure areas formed by the slotted nozzles generally produce uniform pressure profiles extending longitudinally and transversely against the sheet's underside to stably float the glass sheets on a heated gas cushion.

  • Patent number: 6495094
    Abstract: An apparatus and a method for suppressing growth of an oxide film on a coil which is a spirally wound, rolled strip are disclosed. A rolled strip subjected to rolling by hot rolling equipment is wound spirally by a down-coiler to make a coil. Covers are disposed on the opposite sides of the coil such that heat resistant materials intimately contact the opposite sides of the coil. The covers are fixed by L-bolts and nuts to cover the opposite sides of the coil with the covers. In this state, the coil is naturally cooled for a predetermined time to suppress growth of an oxide film and increase productivity.

  • Patent number: 6491865
    Abstract: A heat treat fixture is provided for supporting thin sheet-like work pieces, such as metal gasket layers, during heat treatment to achieve uniform hardness and properties of the work piece while preventing warpage. The fixture has porous, planar support walls that engage the opposite sides of the work piece. The walls include a coarse porous exoskeleton of expanded metal and an inner liner of wire mesh panels that are considerably finer than the coarse exoskeleton. The porous walls permit liquid heating and cooling media during heat treatment to flow freely through the walls for intimate contact with the work piece to achieve rapid uniform heating and cooling. The work piece is supported by the porous walls against movement out of its plane while being permitted to expand and contract within its plane to minimize warpage.
