Abstract: Apparatus for counting particle contamination in a liquid and including a hydraulic cylinder for receiving the liquid and having mechanism for forcing the cylinder piston to exhaust the liquid from the cylinder and into a sensor where the particles are counted. The apparatus includes electric switches connected to the sensor and responsive to the position of the cylinder rod for setting the sensor in various positions for counting. Also, liquid lines are connected with the sensor, and valves are used for directing the liquid to the cylinder and the sensor, and a line restrictor creates the desired pressure in the fluid. The apparatus may receive the liquid from several lines, through a dispensing valve, or it may receive the liquid from a special container.

Abstract: A heavy duty pipe spreader to open formed steel-line pipe, approximately 40 feet long, of approximately 0.250 to 0.750 wall thickness, so as to obtain an approximate 2 inch permanent edge separation prior to O.D. sub-arc welding. The pipe spreader is comprised of an approximately 45 feet long boom, pivotally supported at one end by a vertically adjustable base support and intermediate its length by four hydraulically actuated devices under the boom and mounted to the floor; these devices retract as the pipe telescopes onto the boom. A device at the extreme front of the unit centers and assists in stabilizing the pipe and unit during spreading. The pipe is received on five support rollers, the first of which drives the other four, and all of which are fixed in place and rotate only to move pipe over the vertically adjustable boom. Attached to the boom structure are five sets of pivoted arms which are operated by wedge devices attached to a center pull rod.

Abstract: A vehicle has a bed divided into a plurality of bays by means of dividers. Article carriers are constructed to be positioned in the bays by means of a loader-unloader such as a lift truck. Each article carrier is provided with at least one locking mechanism which automatically unlocks when engaged by a loader-unloader, and automatically locks into the bed of a truck when released by the loader-unloader after being positioned in a chosen bay.
