The vise has a lower stationary jaw member and an upper movable jaw member and a means for moving the upper jaw member vertically toward and away from the stationary jaw member to grip a cable between the jaw members. The lower jaw member has an upwardly opening cable receiving recess therein and the upper jaw member has a downwardly opening cable receiving recess therein for gripping the outer surface of a cable without crushing or damaging the cable. The vise includes a generally C-shaped mounting clamp with a clamping means for gripping a support adjacent its edge to secure the mounting clamp to the support.

Abstract: An bit driver apparatus having three joined hollow tubular sections with a flexible cable member extending through the hollow portions usable when tight turning adjustments are needed, such as in motorcycle carburetor adjustments. A rotatable handle is fixed to one of the cable's ends and a magnetic bit holder is located within the opposite hollow section such that rotation of the handle causes the holder and its mounted bit to rotate and turn an engaged screw or nut. The second joining hollow second between the other sections is bent at an angle of about 45 degrees with respect to the first handle section and the third bit holder second is joined to the second section at about the same angle but extending in the reverse direction. A supporting outer sleeve provides lateral support for the bit while in its holder.

Abstract: An improved apparatus for cutting and stripping insulated wire. The apparatus includes a pair of cutting heads which are mounted on a supporting structure in opposed relation and each head includes a cutting blade and a stripping blade which is located downstream of the cutting blade. The insulated wire is fed between the cutting heads by a pair of endless belt feed units, one of which is located upstream of the heads and the other is located downstream of the heads. Each feed unit includes an endless timing belt, and the belts of each feed unit cooperate to move the wire in both a downstream and upstream direction during the programmed sequence of operation. The belts of each feed unit are moved in a direction toward each other by a chain drive and a torsion spring is operably connected to the chain drive in a manner such that operation of the chain drive in a direction to move the belts toward each other will increase the force of the torsion spring to provide a yieldable force against the wire.

Abstract: A closure panel hemming apparatus includes a lower support supporting a lower hemming die and an upper support spaced from and mounted above the lower support supporting an upper hemming die. The upper and lower supports are relatively vertically moveable for bringing the dies toward and away from one another. A plurality of actuators of the ball screw or rack and pinion type is driveably connected to draw together the upper and lower supports, bringing the dies together for edge hemming preformed metal panels nested between the dies. Force application means including one or more clamps are actuated to connect the upper and lower supports upon their movement of the dies to a hemming position. Force is applied to the clamp(s), through separate means or by intensification means driven by the actuators, to draw the dies tightly together for completing the hemming operation.

Abstract: A spike removing system for removing deeply embedded spikes from railroad tracks. The inventive device includes a housing having an open end, an upper hydraulic cylinder attached within an upper portion of the housing, a lower hydraulic cylinder having a plurality of opposing first jaws and second jaws pivotally attached thereto, and a plunger head attached to the lower hydraulic cylinder for closing and separating the opposing first jaws and second jaws with respect to one another. The first and second jaws are preferably S-shaped and include a channel for allowing the opposing jaw to slidably move with respect to the other jaw. The jaws project downwardly when closed upon a spike, thereby digging into the tie to ensure proper engagement with the head of a deeply embedded spike.

Abstract: In a chemical-mechanical-polishing (CMP) process, semiconductor substrates are rotated against a polishing pad covered by a layer of polishing slurry. A polishing pad maintenance apparatus is developed to reduce glazing effects, enhance the pad's operating life, achieve uniform planarity through a constant polishing rate, and minimize scratches or other defects from the polished surface, during a chemical-mechanical polishing process. This invention combines both the removal of particles and debris while effectively conditioning the pad surface. The polishing pad maintenance apparatus performs three main functions: loosening particles and debris; conditioning the polishing pad; and, removing the remaining particles and debris that result from the slurry and conditioning processes. The three functions are performed in sequence by a forced fluid spray, an abrasive mechanical agitator, and a vacuum.

The angle adjusting base adjusts the angle of the clamp frame to suit to the door of a car, and the jack lifts them to a height needed. Then the distance between two clamp rods of the clamp frame and then the distance between the two clamp rods and a lateral tube are adjusted according to the size of the door of a car to be separated or attached. Thus the door or tailgate of a car is securely clamped by the device, permitting only one worker perform separating or attaching work with easiness and convenience.

Abstract: A method for machining a spectacle lens includes the step of inputting shape data of a spectacle frame opening or shape data of a shaped disk into a computing unit of a CNC-controlled spectacle lens grinding machine. Personal optometric data of a patient are input in the computing unit. A first radius of a front face of the lens blank and a second radius of a rear face of the lens blank as well as the thickness of the lens blank are input the Alternatively, the first and second radii and the thickness of the lens blank are calculated from the optometric data. The front edge curve and rear edge curve of the spectacle lens are either calculated from the shape data of the spectacle frame opening and the optometric data or based on the shape data of a shaped disk, the first and second radii and the thickness of the lens blank. The spacial curve of a suitable V-shaped bevel on the peripheral lens edge between the front edge curve and the rear edge curve is calculated.
