Abstract: An electronic adaptive control system for use with hydraulic press brakes to provide compensation for material spring back to accurately produce a desired bend angle in the work piece with a single ram stroke. Fixed input parameters associated with the press brake and material properties, together with ram position and force data are continuously input to a digital computer which calculates the precise point of punch penetration necessary to reverse ram movement in order to produce the desired bend angle in the work piece. By using in-process measurements, a significant savings in machine set-up-time can be achieved in order to produce an accurate bend angle in the work piece the first time and every time.

In use, the cable-engaging means is positioned on the cable at the location of the desired bend, the lever arm is attached to the second end of the torsion arm, and the lever arm is rotated to apply force to the cable via the torsion arm. The invention enables the bending of cables within breaker boxes or other restricted areas with a simple, hand-held tool.

Abstract: A multi-station strip metal forming press has a safety release mechanism for the transfer slide to protect the press components in the event of a jam or internal breakage. A press frame has a plurality of horizontally spaced work stations and supports a vertically reciprocable ram; a plurality of tools carried by and movable with the ram, positioned to be operatively disposed at the stations and cooperate with dies thereat to perform work on workpieces positioned at the work stations. A horizontally movable transfer slide and associated transfer rails are provided for carrying workpieces sequentially in a predetermined manner to the stations. A powered mechanism reciprocates said transfer slide and ram in timed relationship. A safety release mechanism for the transfer slide operatively disconnects the powered mechanism from said transfer slide on the occurrence of a jam anywhere in the press regardless of the point in the cycle of press operation or position of the jam and causes the transfer slide to stop.

Abstract: Apparatus and method for fabricating a multi-wire harness assembly are disclosed. The harness consists of wires which are first terminated en masse on one level, then loaded en masse into a connector block on a conveyor at a lower level. Wires are then fed to diverse lengths, cut and stripped, and the trailing ends are transported on a conveyorized clamp which parallels the connector block clamp. The apparatus utilizes a shuttle having telescoping wire guide tubes which are directed by a pivotable track first to an operating zone for termination. The shuttle has a clamping mechanism so that the terminated leads are drawn into the expanding tubes as the shuttle retreats. The track then pivots to the level of the connector, the shuttle moves against the connector block to load the terminated leads, and the clamp is released as the shuttle retreats from the block over the wires.

One base is connected to one end of a tie bar, which is pivotally fastened at the other end to a piston rod in a working cylinder. The working cylinder is pivotally fastened to a corner of a triangular straightener, another corner being pivotally fastened to one part of the other base, and the side opposite this corner bearing a thrust block or roller, which presses against the other longitudinal side of the bend of the pipe.

Abstract: A tool for bending articles having a bead or rolled edge is provided with levers defining handles and arms. Removably mounted on the arms are a male jaw member and a female jaw member having substantially complementary arcuate workfaces and grooves to receive the bead. The workface of the female jaw member preferably has a radius of curvature that gradually increases along the width of the female jaw member. Each jaw member is provided with a ledge which engages with an outobard surface of a slot in each arm to add rigidity to the jaw member to prevent warpage during use.

Abstract: A process for the manufacture of a printed circuit board is disclosed in which, during the process, conductive tracks 6 are tested for defects 8 relating to their conductivity and any detected defect 8 is repaired by securing a conductive bridge-piece 9 across the defect 8 by a reflow soldering operation. The repair is encapsulated with a protective layer 16 and the manufacturing process, which includes the further application of heat to the circuit board, is continued.

Abstract: An apparatus for bending an elongate member with a pair of spaced parallel planar flanges which normally extend from the planar web to form a channel section. The apparatus includes a platen shaped for close fitting engagement with the exterior web and flange faces of the elongate member in a region where the elongate member is bent. The platen also includes a counter-pressure member, one surface of which engages the exterior face of the web of the elongate member in the bending region. The counter-pressure member is capable of being selectively advanced or retracted within the platen. A movable head member shaped for close fitting engagement with the interior web and flange faces of the elongate member in the bending region has projections which apply a force in the bending region acting in the planes of the flanges on longitudinally spaced portions of the elongate member for relative displacement of the portions.

Upper crossheads are connected with the upright columns. The upright columns are constructed as tension-compression elements and may include tension rods. The table along with the upper and lower crossheads and possibly the upright columns can be cast of concrete.

Abstract: A tube bender construction for manual operation in bending a tube. The tube bender includes a mandrel defining a bending groove into which the tube is urged by a forming member mounted to the mandrel to swing about a bending axis of the bending groove. The tube to be bent is held against longitudinal movement during the bending operation by tube-holding structure arranged to clamp the tube against an extended groove portion of the mandrel. Movement of the forming member about the bending axis is effected by manipulation of a pair of handles which are arranged in offset manner to permit crossover of the handles and avoid interference between the user's hands thereon in the tube bending operation. The mandrel further defines an extension adapted for mounting thereof in a vise or the like. The handle connected to the mandrel is removably connected thereto as for removal when the mandrel is vise-mounted.

Abstract: An electronic device (10) is attached to a carrier tape (20) by a cluster (22) of leads (12) which are closely spaced relative to each other. The device (10) is detached from tape (20) along with the leads (12) and tape members (28) interconnecting such leads (12) for maintaining the spacings therebetween. The leads (12) are formed with a given configuration while the members (28) are still attached. Such members (28) are then trimmed from the leads (12) to electrically isolate such leads (12) while still maintaining the desired spacings therebetween.
