Abstract: A fluid distribution apparatus including a housing configured to receive a drilling material and direct the drilling material onto a separatory surface; and a damper coupled to the housing and configured to distribute a flow of the drilling material onto the separatory surface is disclosed.

Abstract: A wellbore strengthening material collection system including a vibratory separator having a top deck, a middle deck, and a bottom deck, and also including a collection trough coupled to at least one of the decks and configured to receive wellbore strengthening materials from the at least one of the decks. Additionally, a collection trough including a body having an inlet and an outlet, an angled surface disposed within the body and at least on extension surface extending form the body and configured to secure the collection trough to a vibratory separator.

Abstract: A magnetic clamping system for a shale shaker including at least one screen having at least two side ends extending between a first side and a second side and at least one attachment surface. The system further includes at least one mating surface of the shale shaker configured to receive the at least one screen, and at least one magnet disposed between the at least one screen and the shale shaker, wherein the at least one magnet is configured to magnetically couple the at least one screen directly to the shale shaker. Additionally, the system includes at least one decoupling apparatus, the decoupling apparatus having a handle disposed proximate a perimeter of a shale shaker, and at least one shaft that extends horizontally between the handle and one of the at least one magnet, wherein the handle is rotatable to reverse the polarity of the magnet.

Abstract: An apparatus is presented for performing standard cell intercomparisons. An operator selects two cells in order to compare their relative voltage values. A first terminal on each cell is coupled through a common line switch associated with that cell to a common line. A second terminal on each cell is similarly coupled through an associated A switch to an A line and through an associated B switch to a B line. A potentiometer can be used to compare the voltage on line A with the voltage on line B to determine the relative voltage difference between the cells. Various mechanisms within the apparatus insure protection of the cells.

Abstract: A device mountable on top of a truck cab so to automatically warn a truck driver if the truck body can clear underneath a bridge or other overhead structure; the device consisting of an upwardly telescopic rod that is adjustable to the height of the truck body or box and which, upon contact with any overhead object, will flex and bend over so to act as a switch arm of a switch for closing an electric circuit to either a light on the dashboard or other signalling device to the driver.

Abstract: A footstep carried by a cab of a large automotive truck so that a driver of the vehicle can more easily step up or step down between the cab and ground; the footstep being vertically movable so to minimize a stepping distance; the device including a hydraulic or pneumatic powered cylinder having a slidable piston to which the footstep is rigidly secured.
