Abstract: An adjustable bar-guiding device includes at least one pair of complementarily-shaped jaws which are slideably associated with a fixed frame with the interposition of at least one movement lever mechanism which is actuated by at least one fluid cylinder. The jaws perform a translational motion according to a stroke of mutual approach/spacing apart, between a first configuration of substantial juxtaposition of their respective surfaces and a second configuration in which the surfaces are located at a predefined distance for containing a bar.

Abstract: A vise jaw accessory that attaches to a conventional vise having a unique means of mounting above the vise, using a set of accessory jaw brackets, front and rear, with special mounting provisions for each, capable of supporting and positioning a set of accessory jaws that hold and stabilize a wide variety of irregularly shaped objects by means of opposing arrays of spring-loaded pins capable of individual deflection. The jaws are designed to be interchangeable to accommodate work types ranging from delicate to heavy-duty, as well as flat faces or other jaw face types.

Abstract: A gripping apparatus is disclosed. The gripping apparatus includes a first finger including a plurality of first sawteeth along a first longitudinal end and a receiving area being located between adjacent sawteeth and a second finger including a plurality of complementary sawteeth juxtaposed from the first sawteeth. One of the first and second fingers is movable relative toward the other of the first and second fingers such that an object to be gripped is positioned in the receiving area by one of the plurality of complementary sawteeth. The object is releasably retained against the receiving area by the second finger. A method of gripping an object is also disclosed.

Abstract: A composition for the cleaning of residues from substrates from about 0.01 percent by weight to about 10 percent by weight of one or more fluoride compounds, from about 20 percent by weight to about 50 percent by weight water, from about 20 percent by weight to about 80 percent by weight of an lactam solvent and from 0 to about 50 weight percent of an organic sulfoxide or glycol solvent. The composition has a pH between about 6 and about 10. Additionally, the composition optionally contains corrosion inhibitors, chelating agents, surfactants, acids and bases. In use of the composition, a substrate is contacted with the composition for a time and at a temperature that permits cleaning of the substrate.

Abstract: A gripper which is structurally simple and can reliably and quickly grip small articles of various different shapes. The gripper has a base including a fixed portion and a movable portion movable longitudinally toward and away from the fixed portion, a first gripper portion provided on the fixed portion, a second gripper portion provided on the movable portion, and a moving/fixing mechanism for gripping a small article of an indefinite shape by moving the second gripper portion toward the first gripper portion.

Abstract: A gripping device which can grip small articles of different shapes without the need to work its chucking surfaces or to use blocks and liners in combination, and which can position articles in parallel to or perpendicular to a reference surface with a single gripping device. A fixed yoke, a movable yoke and an anvil-side yoke are connected to two columns so that all the yokes can pivot relative to the columns and the movable yoke can further slide relative to the columns to form a parallel crank mechanism. The fixed yoke is provided with a threaded shaft for moving the movable yoke. V grooves are formed in opposed surfaces of the movable yoke and the anvil-side yoke. A plurality of cuts are formed at the portion where the V-grooves are formed in parallel to the columns. The cuts define plate members having V-grooved gripping portions meshing with each other.

Abstract: A clamp for dipping printed circuit boards into a solder bath of a solder coater machine is disclosed. The clamp comprises first and second interdigitated, coplanar fingers connected respectively at common ends thereof to a pair of spaced, parallel first and second plates. Pivot pins respectively connect adjacent first and second fingers to each other to define a pivot axis extending parallel to and between the distal ends of fingers and the first and second plates. The second plate is spring biased from and movable towards the first plate under an applied actuating force to pivot the second fingers out the plane of the first fingers enabling insertion of a printed circuit board between clamping surfaces defined by the distal ends. The pivot pins and spring mechanism are spaced a sufficient distance from the distal ends to avoid contamination by solder particles and flux during the coating process and to avoid interference with air leveling knives closely spaced to the coated board upon removal from the bath.

Abstract: A clamping device for rectangular configurations characterized by two opposed jaws each having right-angled jaw portions and each pivotally mounted on separate support means for movement to and from each other so that the jaws form rectangular openings with self-adjusting aspect ratio for holding a rectangular workpiece.

Abstract: A method and apparatus for machining on a rotary lathe (L) the bearing journal (14) of an elongate rotary drill bit body section or so-called lug (W). A workpiece holder (H) adapted to be removed from and positioned on the lathe (L) grips the bit body section (W) in a predetermined position. The holder (H) with the drill bit body section (W) is inserted loosely within an inclined pocket (O) on the lathe (L) defined by parallel upper and lower planar surfaces (74, 76). Positioning pins (86) on the lathe (L) engage the lower surface of the holder (H) and move the holder (H) against the upper planar surface (74) of the pocket (O) for the machining operation. After the machining operation on the bearing journal is completed, holder (H) is released by the positioning pins (86) and the holder (h) with the finished bit body section then removed from the lathe (L).

Abstract: A vee block clamp is provided intended chiefly to hold items having a curved outer surface. The clamp comprises a plurality of clamping blocks with oppositely facing inclined edges cooperating to define a vee shaped support surface. The dimensions of the support surface are adjusted according to the size of the item to be supported by longitudinally sliding the clamping blocks toward and away from each other. The clamping blocks are constrained for horizontal sliding motion only so that the blocks are prevented from rotating relative to each other.

Abstract: Manually-operated field apparatus is disclosed for applying a pressed-on coupling to the end of a hose. A frame carries two threadedly-adjustable sets of interleaved clamping plates for clamping a hose end therebetween in a predetermined orientation. The frame defines a pair of tracks on opposite sides of the hose parallel thereto, on which are respectively slidably mounted two runners of a coupling carriage for supporting the coupling between the runners coaxially with the held hose end. A manually-operated ball-type screw and nut assembly mounted on the frame is engageable with the coupling carriage for moving it along the tracks toward the hose end for pressing the coupling onto the held hose end.

Abstract: A pipe-gripping vise accessory has a first jaw with a fastening device for removably affixing it to a first face of a first clamping member of a vise. The first jaw has a back in juxtaposition with the first face of the first clamping member when affixed thereto and a front spaced from the back and formed in a plurality of stepped teeth following a semicylindrical pattern. A second jaw has a fastening device for removably affixing it to a second face of a second clamping member of the vise. The second jaw has a back in juxtaposition with the second face of the second clamping member when affixed thereto and a front spaced from the back and formed in a plurality of teeth following a semicylindrical pattern.

Abstract: A pair of V block centers, for being used with a conventional V block, in order to support and center any rectangular stock upon the V block, while being machined; the pair of V block centers each consisting of an elongated rectangular bar, which has one of its longitudinal corners cut out to form an inside square corner, in which a rectangular work piece is positioned, an opposite longitudinal corner of the bar being cut off at a forty-five degree angle, in order to rest against the angular face of the conventional V block, the V block centers thus supporting the work therebetween, while a conventional V block clamp then holds the work secure therein.
