Abstract: The invention is directed to a device for the concentration of fluids comprising a donor receptacle containing a fluid to be concentrated, the donor receptacle comprising a plunger; a receiving receptacle to receive the concentrated fluid, the receiving receptacle comprising a plunger; a concentrator device that is connected to the donor receptacle and the receiving receptacle; and a housing that encloses the donor and receiving receptacles and the concentrator device that the plungers of the donor and receiving receptacles are enclosed within chambers that are gas tight.

Abstract: The invention is directed to a work station for use in performing processing of patient samples, storing equipment and drugs in a hospital and the like, the cart having a lower housing having caster wheels mounted on the bottom thereof, the lower housing having angular-shaped side panels therearound which may be opened for entrance into all sides of the housing, and one or more of the side panels; an upper housing mounted on top of the lower housing, the upper housing having one or more side panels therearound; and one or more work areas mounted on top of the upper housing, the shelf adapted for receiving point-of-care equipment.

Abstract: A system for controlling slack in a winch rope associated with a vehicle can include a winch, a plow, and a support member pivotably coupled to the plow and carrying a pulley that receives the rope for raising and lowering the plow. A limit switch can be operatively associated with the winch and configured to selectively enable and disable lowering of the plow by the winch. A first member can be carried by the support member and operatively associated with the switch. A biasing member can bias the support member to a first position when a load on the winch rope is below a predetermined threshold. The first member can be in at least substantial alignment with the switch when in the first position. The switch can change an activation state upon the first member being in the first position to automatically disable lowering of the plow by the winch.
