Abstract: ABSTRACT     A simple, low mass, low cost, articulating/articulating and rotating wrist assembly for use on automatic machine tools to provide two important degrees of freedom of movement of an end effector tool in the form of an articulating motion. either alone or in conjunction with a rotating motion.          Where both rotation and articulation are used the sequence is important in order to obtain new and different movements of the end effector tool for transcribing cones, etc.  The fundamental articulating motion is achieved through the  kinematics of a primary, parallelogram-type pantograph driven remotely from the automatic machine tool and employing a secondary restraining mechanism either in the form of a secondary parallelogram-type restraining pantograph or a cluster of sun, idler and planet gears.  The wrist assembly can be used in conjunction with any of the known automatic placement machine tools whether operable only along a single dimensional axis, within a plane defined by two orthogronal axes or a three dimensional space.  The configurations and relative size and length and location of the linkages comprising the pantograph are dictated by the particular amplitude and sector of motions in space that are required for any given application for which the wrist mechanism is designed and the kind of scribing movement of the working tool desired.

A socket in-cluded in such device comprises an insulative housing and first and second pluralities of contacts supported thereon arranged in laterally spaced, longitudinally corresponding positions.  Each of the contacts has a first end portion selectively plated, with gold for example, for detachable connection to a conductor of the electric component.  A second end of the contacts is selectively tin-plated and soldered to the leads of the IC package.  The second end portion of each of the contacts is formed to have thereon at least two laterally spaced contact members, thereby providing for selective securement thereto of IC packages having different laterally spaced leads.

Abstract: ABSTRACT    PROCESS FOR TREATMENT OF PHOSSY WATER FOR RECYCLING    In  the  electric  arc  furnace production of  elemental phosphorus, cold phossy water is segregated from hot phossy water.   The cold phossy water is discharged to a lined pond wherein solids settle to form a clarified cold water which is recycled for cooling and washing purposes.   The hot phossy water is passed through a lamellar settler wherein phosphorus and solids are separated as a sludge to form a clarified hot water.  The clarified hot water, without requiring additional heat, is recycled for process use.  Phosphorus is recovered from  the  sludge  to  reduce  to  a minimum  the  amount  of phosphorus discharged with dirt from the hot phossy water to the pond.

Abstract: ABSTRACT     Thrombus formation in an implantable blood pump is prevented by using a close-tolerance purge seal for the impeller shaft or rotor.  A blood-compatible fluid is used for the purge fluid (which is preferably also the bearing fluid), and the purge flow into the blood stream presents to the blood stream a benign interface between the rotating and stationary parts of the pump.  The rotat-ing and stationary surfaces adjacent the interface are so configured as to present an essentially continuous smooth surface across the interface which can be swept by the blood stream and presents no cavities in which the blood can stagnate.  The close clearances of the purge seal allow a sufficient purge flow rate to be maintained with only a minute amount of purge fluid; and in accordance with one aspect of the invention, the purge fluid can be derived from the blood stream by a protein-filtering membrane system so that no external replenishment of the purge fluid supply is necessary.

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of detented work locators are embedded in a plastic fixture pallet so the first such locator is in a predetermined position in said pallet, and so that said second locator is positioned in a predetermined location with respect to said first work locator. Each locator may be formed with a base plate sandwiched between a pair of circular ring members and so that there is formed through such members a centrally disposed circular opening.  A locator pin is inserted through said opening and locked in place therein by cooperation of a detent ring which is press fit within said central opening proximate an upper portion of said locator pin.  A lower ledge of the locator pin is disposed in a lower portion of said central opening and is spring biased so that detent notches formed in a lower surface of the detent ring seat on detent balls positioned between the detent ring and the base plate.  A cross pin extends through the locator pin perpendicular to the axis of rotation thereof.  A work base is formed with a pair of spaced openings with opposed notches in each so that when the cross pins of the two locators are aligned with the notches the base can be placed over protruding upper ends of the locator pins.  Subsequent rotation of the cross pins, under action of the detent ring and balls, moves the cross pins into positions locking the base and work against the fixture pallet surface.  One opening in the tray snugly fits about one of the locator pins to provide an accurate location of the work carrying tray on the fixture pallet. The other tray opening accommodates variations in part dimensions by being slightly elongated. Work positioners at a work station cooperate with the locators to accurately position the fixture pallet and work at the work station; said work positioners also functioning to rotate the work locators.

Abstract: ABSTRACT OF THE DISCLOSURE         The device for restraining a truck or transport trailer at a loading dock comprises a frame having a vertical securing face and a lower horizontal securing face for mounting of the device to a structure such as a loading dock and at least partially supported by  driveway in front of the loading dock. A pivotal bar member having one end pivotally secured to the frame above and intermediate the length of the lower horizontal bearing face and outwardly of the vertical securing face is movable from a generally horizontal vehicle release position to a vehicle restraining position with the bar generally perpendicular to the lower horizontal bearing face. The bar is moved by a hydraulic cylinder pivotally secured adjacent the forward end of the lower horizontal securing face and pivotally secured to said bar member to be angled rearwardly towards said vertical securing face.  The cylinder is pivotally secured to arms extending below the bar beyond the pivot securement of the bar to the frame.  The hydraulic cylinder, when actuated to extend, forces the bar to move from the vehicle release position to the vehicle restraint position.  The pivot connection of the bar is spaced from the vertical securing face at least about nine inches to accommodate therebetween a vehicle IC bar.  The pivotal bar, cooperates to define an area for confining an IC bar and restrain the IC bar in this confined area in the event that the truck or tractor trailer is advertently moved away from the loading dock without following the proper steps for disengaging the truck restraint system.  The arrangement is such to place the cylinder in compression in the event of unauthorized removal of the truck or trailer, with a large portion of the load being transmitted to the horizontal bearing face.
