  • Patent number: 9296624
    Abstract: A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. The compact and portable liquid concentrator is mountable on a truck bed or skid for easy transportation to remote sites.

  • Patent number: 8671521
    Abstract: A control motion hinge, comprising a first leaf hinge with three knuckles to secure a first pin, wherein the two outer knuckles have roller knuckles, a link having a two knuckles on a first end to interlock with the first leaf hinge and a single knuckle on a second end, a second leaf hinge with two knuckles to secure a second pin when interlocked with the second end of the link, wherein the two knuckles of the second leaf hinge have a roller path for engaging the roller of the first leaf hinge, wherein such rollers traverse the roller path, a first spring device positioned between said first leaf hinge and said link to apply a force therebetween, and thus softly closing the door reducing the sound of closure during the final approach of the door.

  • Patent number: 6684896
    Abstract: A valve assembly includes a valve with a bobbin/valve body, a solenoid and a plunger. The bobbin/valve body is formed in one piece, and defines all of the valve's inlet/outlet ports and forms the entire support structure for the solenoid and the plunger. The valve may be connected to a manifold by press-fitting port nipples of the valve into corresponding channels in the manifold. The manifold is formed of a resilient, elastomeric material, and the port nipples include radial projecting barbs, which enable the valve to be fluidly-connected to the manifold without additional O-ring seals or other mechanical sealing devices. Fittings with barbs can likewise be press-fit in other channels of the manifold to connect the valve assembly with fluid lines or other components in the fluid system. The fittings can also be provided unitary with the manifold, and/or adhesively attached to the manifold and/or to the fluid lines and other components.
