摘要： An apparatus and method for interconnecting a drill collar and a stabilizer in axial alignment is disclosed. The tool includes an upper plate and a lower plate held in spaced, parallel relationship to one another with the upper plate having a plurality of peripheral holes around it. A plurality of rods project between the upper and lower plates, each one of the rods being mounted at a bottom end to the lower plate and inserted adjacent its top end in sliding relationship through one of the peripheral holes in the upper plate. A spring is placed around each of the rods for biasing the top plate away from the lower plate, and an attachment pin projects downwardly from the lower plate for insertion into a kelly pin hole on an oil rig. A stabilizing pin projects upwardly from the upper plate, and a rotatable plate is rotatably secured to that stabilizing pin intermediate the ends of the stabilizing pin. A heavy stabilizer having an internally threaded end can then be placed on the rotatable plate, and a drill collar with an externally threaded end can be brought into axial alignment with the threaded end of the stabilizer. While the stabilizing pin holds the stabilizer in an upright position, the rotatable plate is rotated to threadably engage the drill collar and stabilizer. The rotatable plate is spring biased and therefore yields in response to heavy loads imposed upon it, thereby allowing the stabilizer and drill collar to be threadably interconnected without damaging the threads.

摘要： A one-piece fiberboard carton having an integral dispensing flap. A tear strip is drawn along an edge of the dispenser flap which is formed intermediate the top and bottom edges of the front surface of the carton so that the flap may be pulled out of the plane of the front of the carton and disposed at an angle with respect to the carton so that when the carton is placed on a side, product stored within the carton can be dispensed by gravity feeding it through the opening adjacent the dispenser flap. Alternatively, the dispenser flap may be taped by adhering a tab to the front wall of the carton which may be cut along a line to open the same. Oppositely disposed web corners attach the dispenser flap at an acute angle to the front wall of the carton so that when it is opened, the product will not fall from the carton unless the carton is intentionally placed on its side in a dispensing position. By use of the web-connecting flaps, the dispenser flap may be opened and closed, as needed, to open and close the carton before all the product is dispensed, to dispense and store any remaining product.

摘要： A diaphragm actuated-rod operated valve assembly adapted for installation in a fluid flow is disclosed comprising a one-piece elastomeric valve-spring-seal member which is operated by the push rod and has only a static seal and in addition is provided with internal support such as to prevent an otherwise collapsible portion of the valve from grabbing the operating rod as a result of external pressure and thereby inhibiting valve operation.

摘要： A two piece torque release mechanism includes a metal cover having a peripheral flange with a plurality of circumferentially spaced, cam surfaces each including ramp and notch segments intersecting at a sharp radius point radially inwardly of a land segment; a plurality of integrally formed fingers on a driven member are sprung radially outwardly into operative engagement with the cam surfaces. Each finger has a sharp radius tip portion formed by the intersection of a flat radial surface and an inclined slip surface; the radial surfaces and notches define a positive interlock between the cover and the driven member for removing the driven member; the slip surfaces are mateable with the cam ramp segments to produce a torque release couple between the cover and the driven member to prevent overtightening of the driven member and to produce a reverse slip movement of each finger following torque release for parking the tip portions against the cam land segments so as to maintain the fingers in an unstressed position when the driven member is in place.

摘要： A rocker arm in an internal combustion engine is pivotably supported by a fixed fulcrum retainer with a rocker key operatively positioned therebetween. The rocker arm and fulcrum retainer each have a concave, semi-cylindrical bearing surface and the rocker key has a pair of spaced apart, opposed convex, semi-cylindrical bearing surfaces, the concave, semi-cylindrical bearing surfaces and associate convex, semi-cylindrical bearing surfaces having radii ratios on the order of 1.7:1 to 3:1 and preferably 2:1 whereby to effect substantial rolling contact of these elements relative to each other. In addition, the rocker arm is preferably of U-shaped configuration as defined by a base with side walls depending from opposite sides thereof. A roller follower is operatively and rotatably positioned between the side walls at one end of the rocker arm, with the roller follower having an outer peripheral surface of a diameter whereby the outer peripheral surface is in rolling contact with the base and an associate element of the valve train at this end of the rocker arm. A roller support shaft is operatively associated with the side walls and with the roller follower to loosely retain the roller follower in unit assembly with the rocker arm.

摘要： An engine cooling-passenger heating system is disclosed having an integrated multi-mode valve arrangement which operates in a no-heat mode to bypass all available flow to the passenger heater past the heater for continued circulation without disruption in the engine cooling system and further operates in a heat mode to effect flow through the heater while also being responsive to the pressure drop across the heater above a predetermined value to also simultaneously establish in the heat mode a restricted connection bypassing a portion of the available coolant to the heater to thereby limit the flow through the heater as well as the pressure differential acting thereon.

摘要： A container consisting of cooperating top and bottom trays. Each tray has opposed upstanding end walls and opposed upstanding side walls. The height of the end walls of each tray are greater than the height of the side walls of the same tray. In order to assemble the two trays together to form a container, the two trays are inverted relative to each other so that one tray forms a top and the other tray forms a bottom. The two inverted trays are rotated 90.degree. so that the taller end walls of one tray cooperates and telescopes over the shorter side walls of the other tray to form a container.
