  • Patent number: 4840485
    Abstract: Frequency domain cross-correlation fluorometers may be improved over present designs by providing a coherent signal at one frequency to means for detecting luminescence from a sample, which is elicited by light modulated at another frequency, in which the two frequencies, obtained from a pair of phase-locked loop frequency synthesizers, are different from each other by at least 100 hertz, which is a significantly greater difference than used in corresponding prior art fluorometers. This permits the use of the phase-locked loop frequency synthesizers, rather than the currently used direct synthesis synthesizers, providing significant advantages.

  • Patent number: 4829002
    Abstract: A system for metering nutrient media to cell culture containers includes a media flow conduit which defines at one end means for substantially aseptic communication with the source of the media. In a preferred embodiment, sterile connectors may be used for essentially sterile conditions. A branch conduit extends from the flow conduit at a location spaced from the ends. The branch conduit communicates with means for receiving a predetermined-volume aliquot of media through the media flow conduit from said one end. The flow conduit also defines a portion downstream from the branch conduit, which communicates with at least one cell culture container, each container being a flexible bag. At least part of the flexible bag is made of a material capable of providing at least 2 times the oxygen diffusion and at least 2 times the carbon dioxide diffusion between the bag interior and exterior, compared with an identically-sized, sealed bag having polyethylene walls 0.013 inch thick.

  • Patent number: 4808106
    Abstract: A mold comprises a molding chamber, a sprue aperture communicating with the chamber for introducing molding compound into the chamber, and a mold gate for regulating molding compound flow through the sprue aperture. In accordance with this invention, the mold gate comprises flexible flap means positioned to restrict flow of molding compound through the sprue aperture. The flap means is positioned to be flexed toward the molding chamber by pressurized molding compound, to permit increased flow of the molding compound through the sprue aperture into the molding chamber. The flap means is capable of returning to their original shape when the pressurized molding compound is substantially released of its pressure, particularly in the circumstance where a suction step in the molding compound pressure cycle provides a negative pressure. The flap means in its original shape at least substantially obstructs the sprue aperture.

  • Patent number: 4807327
    Abstract: A cleaning head for an air flow type cleaner defines an open-faced chamber for facing the surface to be cleaned. An air recirculating conduit draws air from the chamber through a first port in the chamber adjacent one end thereof. A baffle in the cleaning head is positioned substantially between the one end and the first port to reduce the flow of dirt-laden air to the one end. By this invention, one or more apertures provide communication at a central portion of the baffle substantially between the first port and that volume within the chamber which extends between the baffle and the one end, to provide air suction to prevent dirt accumulation in that volume.

  • Patent number: 4802549
    Abstract: A vehicle has first and second drivers' seats and a control console, the control console carrying a plurality of individual controls and display means. The drivers' seats are in side-by-side relation. By this invention, a pivot carries the control console to permit the console to pivot between at least a first position facing the first driver's seat and a second position facing the second driver's seat. Thus, two drivers may operate the vehicle from the same control console in alternating manner. Typically a, releasable lock provides retention of the control console in either of the two positions described above, and also in an intermediate rotating position in which the control console faces between the two seats. Also, cable may communicate with the control console, the cable extending through the pivot for communication with the rest of the vehicle.

  • Patent number: 4773546
    Abstract: A pallet rack discloses a pair of spaced, parallel rails, plus first and second wheeled carts mounted in rolling relation with the pair of rails. The second cart is capable of rolling over the first cart to overlie the first cart without movement-obstructing contact therewith. In accordance with this invention, each rail of the pair comprises a vertical web and a pair of generally horizontal flange portions extending outwardly in opposed directions from the web. The wheels of the carts ride on the flange portions, with the wheels of one of the carts riding on the flange portion of each rail which is opposed to the flange portions on which the wheels of the other of said carts ride. At least a portion of the web stands above the flange portions to limit the lateral movement of the wheels.

  • Patent number: 4770681
    Abstract: A dust trap for flowing gases comprises an inlet conduit which terminates in a transverse wall for impact-type dust separation (i.e. inertial separation). A side entry port is positioned adjacent the transverse wall. The side entry port communicates with the circulation chamber defining an angled opposed wall in the opposite side of the chamber of the side entry port. The angled, opposed wall is substantially perpendicular to gas flow through the side entry port, to cause flowing gas from the side entry port to split vertically into swirling upward and downward flow patterns for further dust separation. The lower part of the circulation chamber is normally closed off from the exterior. The upper part of the circulation chamber communicates with an outlet conduit.
