  • Publication number: 20190249202
    Abstract: An engineered bacterium for producing ethanol from one or more carbohydrates is disclosed. The bacterium can be made by (a) inactivating within a Lactobacillus casei bacterium one or more endogenous genes encoding a lactate dehydrogenase; or (b) introducing into a Lactobacillus casei bacterium one or more exogenous genes encoding a pyruvate decarboxylase and one or more exogenous genes encoding an alcohol dehydrogenase II; or (c) performing both steps (a) and (b). The resulting engineered bacterium produces significantly more ethanol than the wild-type Lactobacillus casei bacterium, and can be used in producing ethanol from a substrate such as biomass that includes carbohydrates.

  • Patent number: 9650206
    Abstract: A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.

  • Patent number: 8607812
    Abstract: A butterfly valve for handling materials where the temperature of the materials flowing through the butterfly valve can exceed the breakdown temperature of the sealing member with the butterfly valve inhibiting contact of hot transportable materials with the sealing member to isolate the hot transportable materials from the sealing member. Cooling conduits maintain at least portions of the valve that contacts the sealing member at a temperature below the breakdown temperature of the sealing member to prevent seal failure.

  • Patent number: 8544654
    Abstract: A magnetic separator comprising a vibratory conveyor for vibratorily flowing non-ferrous articles and articles containing ferrous material within the magnetic field of a transverse extending magnet to magnetically capture the articles containing the ferrous material while allowing the non-ferrous articles to flow therepast. The magnet is periodically retractable to remove ferrous articles magnetically adhered thereto. The use of a set of transverse extending magnets enables a continuous on-the-go separation of articles containing ferrous material from non-ferrous articles without having to shut down the vibratory conveyor.

  • Patent number: 7438090
    Abstract: A flow valve having sealing member having a first condition for engaging a housing to prevent back flow and a platform for obstructing a flow passage through the flow valve with the platform supporting the sealing member in an out-of-the-way condition to allow fluid to flow through the flow valve.

  • Patent number: 7267475
    Abstract: A mixing apparatus and method wherein the mixing apparatus includes a hopper having a port piston for periodically retracting to open a fluid port to allow a slug of gas to be quickly injected into the bottom of a hopper, which produces a mixing and blending of the materials in the hopper as the slug of gas flows upward through the materials in the hopper. The port piston periodically closes to seal the fluid port without allowing the material in the hopper to backflow, which would prevent between the port piston and a hopper sealing member from being brought into sealing engagement.

  • Patent number: 6417464
    Abstract: An attachment for a feeder conveyor with the attachment comprising an angularly positionable gate that is angularly postionable within the trough of a feeder with the postionable gate having a secondary metering outlet so that when the postionable gate is in the down position it partially close off the material flow path within the feeder while allowing only a portion of the solid materials in the material flow path to pass therethrough to thereby extend the range at which material can be controllable and uniformly delivered from the feeder.

  • Patent number: 6305412
    Abstract: A pressure relief valve that includes a sealing arrangement with a cantilevered seal that prevents fluid from escaping from a system if the differential pressure is only slightly positive yet permits fluid to be released from the system if the internal system pressure exceeds a predetermined pressure differential. In a further embodiment, the pressure relief valve includes a further scaling arrangement with a further cantilevered seal, which is normally closed, but if the internal system pressure should decrease below the external pressure a predetermined amount the second scaling arrangement opens to allow fluid into the system to thereby equalize the pressure and thereby prevent collapse of the system.

  • Patent number: 6074136
    Abstract: A multi-port pneumatic switch having a drive system including a motor and a gear reduction box that rotates a rotatable plate which carries a rotateable conduit having an offset end and a non-offset end with the offset end postionable into precise flow alignment with any of a plurality of outlet conduits through the coaction of a photoelectric alignment system that detects a light beam reflection from a reflector on the rotatable plate to immediately shut the power to the drive system and thereby stop further forward rotation of the rotatable plate. With the cessation of power to the drive system a pivotal arm swings into engagement with a radial stop on the rotatable plate to lock the rotatable plate from further forward rotation while the drive system which is powered through a gear reduction drive functions as brake to prevent back rotation of the rotatable plate once the power is shut off to the motor.
