Abstract: A device is provided for controlling fluid flow in oil well casings or drill pipes. The device defines a flowpath for fluid through a casing section or drill pipe with the flowpath including a throttling valve which restricts or prevents the flow of fluid therethrough. This can be used to prevent U-tubing in casings or can be used to locate leaks in drill pipes or can be used to monitor the position of successive fluids of differing viscosities in a casing string.

Abstract: A paint or coating composition and method for detecting vapor or liquid reactants, such as ammonia. The composition is composed of ethyl cellulose as a binder, a filler, such as amorphous silica, and a dye, such as bromophenol blue. The composition serves as a passive detector for vapor or liquid reactants when applied to selected surfaces as a paint. The composition is capable of detecting extremely low concentrations of vapor. Further, the composition is capable of regenerating to its original color, thereby providing repeated detection capability.

Abstract: The seat comprises a front end and a back end interconnected by foldable sides and a top which can be swung into a vertical position and inserted into the back end when the seat is collapsed. The ends are shallow, rectangular boxes with their smaller surfaces oriented top and bottom when the seat is erected. The seat further comprises two handles detachably attached to the back end and stored inside the front end when the seat is collapsed. The sides are hinged such that their centers fold inward when the seat is collapsed, allowing the ends of the seat to move together and be latched together. There are four casters, one at each corner of the bottom of the erected seat and a foot rest which swings or pivots out of the front of the seat. The casters are lockable to prevent the seat from rolling when desired. A carrying handle is attached to the front end of the top of the seat and is accessible for carrying the seat when the seat is collapsed with the top inserted and locked into the back end.

Abstract: A support garment for use during exercise. A front panel is connected to a left rear panel and a right rear panel. A left front panel strap is adapted to be connected to a left rear panel strap, and a right front panel strap is adapted to be connected to a right rear panel strap. A belt is connected to the rear of the garment at approximately the center thereof. The garment enables the wearer's shoulders to provide support to the lower back and gluteal/pelvic area by pulling upward from the shoulders. The two ends of the belt are pulled forward and upward and fastened at the approximately the waist of the wearer.

Abstract: A sheeter machine for processing dough into food products. A pair of rollers are mounted on offset shafts. A cutter mold is supported on pivotal arms. A wedge adjustment apparatus is provided for adjusting the position of the back roller relative to the front roller. A pivotal discharge arm is provided having a spring loaded tensioning assembly. First and second stripper wires are associated with the front roller to allow the cut and molded dough to be stripped from the front roller as it is moving downward toward the discharge arm. Collar assemblies are provided on the ends of the respective roller shafts. A release handle assembly is provided for moving the rear roller away from the front roller. The hopper saddle and the rollers are adapted for mating engagement.

Abstract: A safety shutdown circuit for a pneumatic pump system. The pump system includes a manifold assembly for discharging pumped liquid. The liquid is discharged from the system by a reciprocating piston apparatus which drives a liquid pump cylinder. The pump system is provided with a pneumatic safety circuit for monitoring the stroke time or rate of the reciprocating air cylinder. The safety circuit includes a safety shutdown valve and a pneumatic timer associated with the shutdown valve. The pneumatic timer vents air supply within the safety circuit after a predetermined time interval. If a leak or failure occurs in the pump system, the reciprocating piston apparatus will complete a stroke in less time than the predetermined time as a result of the pressure loss incident to the leak or failure. In such event, the air supply within the safety circuit is directed through the shutdown valve to the pump system START valve to deactivate the system.

Abstract: A scaffolding guard rail post having hooks connected thereto for securing guard rails to the post. The post comprises a longitudinal rod and each hook comprises a longitudinal leg portion connected to the rod and an arm portion. The arm portion has a lower arcuate portion, an upper arcuate portion, a longitudinal web portion intermediate to the lower arcuate portion and the upper arcuate portion, and a longitudinal lip portion. A corner guard rail post has a pair of upper hooks connected thereto and a pair of lower hooks connected thereto. The guard rail posts are secured to a scaffolding frame during usage thereof.

Abstract: A bucket conveyor frame. At least one horizontal section and one vertical section are connected by a curved section. Each section has a central support tube. A plurality of plates connected to the support tube lie in approximately vertical planes. Upper and lower chain hold downs extend the length of the sections. A transport track delivers products from an infeed station to a discharge station and a return track returns the buckets to the infeed station in a continuous loop. Chain sprockets are located within enclosed housings at the infeed and discharge stations.

Abstract: A universal accumulator for utilization in an automotive air conditioning system. An inlet fitting and an outlet fitting are connected to the top of the accumulator housing. The adjustable connection of the outlet fitting to approximately the center of the housing top permits the variable positioning of the outlet port relative to the inlet port and utilization of the accumulator in a wide variety of automobile applications. A method for replacing an accumulator with the universal accumulator of the present invention is also disclosed.

Abstract: A bucket distribution system for receiving products at an infeed station and selectively discharging the products at a plurality of distribution stations. A plurality of buckets travel in a continuous path and each receive a predetermined portion of products at an infeed station. Bucket trip apparatus at each of the discharge stations selectively pivots the buckets in a direction opposite to the direction of bucket travel to cause the buckets to discharge products therein. Feeders at primary distribution stations are adapted to roll in and out of position for servicing. Products may recirculate within the system to thereby reduce the amount of products taken off-line.
