  • Patent number: 7066325
    Abstract: A media storage container includes a back wall with base and lid pages hingedly connected to the back wall. The base page has a hub to hold a first item of recorded media. An internal page is connected to the hinge wall and has a hub on one surface thereof to hold a second item of recorded media and a hub on the other surface thereof to hold a third item of recorded media. The hub on the internal page facing the base page is offset from the base page hub so that each hub helps hold discs on the facing page. Likewise, the hubs on opposite sides of the internal page are offset for the same purpose where additional internal pages are included.

  • Patent number: 6581337
    Abstract: A modular enclosure including first channels and a plurality of second and third channels which intersect the first channel at an angle, and a plurality of panels, each including a wall member and edge members pivotally coupled to the wall member. The wall members are configured to engage the first channel and the edge members are configured to engage the second and third channels. A method of assembling a modular enclosure is also disclosed, including providing a base including first channels, second channels, and third channels, providing a plurality of side panels each having a wall member and a first and second edge member pivotally coupled to the wall member, pivoting the first and second edge members so that they are non-parallel to the wall member, and inserting the wall members into the first channel, the first edge member into second channels, and the second edge members into third channels.

  • Patent number: 5573568
    Abstract: A method of operating a regenerative glass furnace for melting glass for the manufacture of shaped glass articles so as to minimize emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting the combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and contain permissible levels of NOx. Alternatively, the furnace may be operated at substantially stoichiometric conditions and fuel is supplied to waste gases as they leave the melting chamber. The invention also relates to a regenerator glass furnace for use in the method.

  • Patent number: 5569312
    Abstract: A method of operating a cross-fired regenerative glass furnace for melting flat glass so as to minimize emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting the combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and permissible levels of NOx.

  • Patent number: 5407089
    Abstract: A storage container assembly is disclosed comprising a lid (12) and a base container (13). The lid body has a scoop recess (26) foraged in a forward end for collecting articles, and a handle bar (32) extending from the recess to a rearward end wall (24) of the lid. The handle bar has a hand opening (34) therebeneath, and is positioned on the longitudinal center axis of the lid. The lid pivots about horizontal pivot pins (42) to selectively enclose and uncover the top opening (50) of the container, and the lid is detachable from the container upper rim by the handle bar, whereby enabling a user to collect refuse into the scoop recess.

  • Patent number: 5152420
    Abstract: A container for holding cans (C) or the like includes a base container portion (11) and a cover (12). The base container (11) includes a bottom surface (13) with side walls (14, 15) and a rear wall (16) extending upwardly therefrom forming rims (20, 21) defining an open top for the base container (11). A front wall (17) also extends upwardly from the bottom surface (13) and includes a U-shaped door frame (18) formed at the top thereof. The bottom surface (13) is undulated to form peaks (29) with a valley (30) therebetween configured so as to neatly receive the cans (C). The cover (12) includes a top surface (33) having a downturned rim (34) resting on the rims (20, 21). A living hinge (36) connects top surface (33) to a door (37) which is received within door frame (18). Cans (C) passed laterally through door (37) are automatically stacked on the undulated bottom surface (13) of the base container (11).

  • Patent number: 4399414
    Abstract: A low-noise pulse conditioner is provided for driving electronic digital processing circuitry directly from differentially induced input pulses. The circuit uses a unique differential-to-peak detector circuit to generate a dynamic reference signal proportional to the input peak voltage. The input pulses are compared with the reference signal in an input network which operates in full differential mode with only a passive input filter. This reduces the introduction of circuit-induced noise, or jitter, generated in ground referenced input elements normally used in pulse conditioning circuits, especially speed transducer processing circuits.

  • Patent number: 3974402
    Abstract: A logic level translator utilizes a TTL logic gate, a current switch, and a clamp circuit to convert CML level binary signals into TTL level binary signals. The translator provides isolation between the TTL ground and the CML ground in order to reduce noise in the CML portion of the circuit. The clamp circuit prevents a switching transistor in the current switch from reaching saturation, thereby increasing the speed of operation of the translator. A portion of the current switch provides a quick pulldown of a switching transistor in the TTL circuit to reduce noise in the TTL circuit.
