Abstract: A method and an apparatus for grinding the surface of a semiconductor wafer by moving a holding table and a grinding wheel relative to each other in a predetermined direction substantially parallel to the surface of the semiconductor wafer held onto the holding table to cause the grinding wheel which is rotated to act on the surface of the semiconductor wafer held onto the holding table. The semiconductor wafer is placed on the holding table with its angular position being regulated so as to direct its crystal orientation in a predetermined direction with respect to the holding table, and thus the grinding direction of the surface of the semiconductor wafer by the grinding wheel is set in a predetermined relationship to the crystal orientation of the semiconductor wafer.
Abstract: A surface blasting apparatus including a wheel mounted chassis carrying a detachably mounted blasting head assembly. The blasting head assembly includes a housing enclosing a blasting wheel mounted for rotation about an axis extending parallel to a surface to be cleaned. The housing further includes a return chute through which abrasive returns after impacting such surface. A baffle assembly and magnetic arresting assembly cooperate to clean the abrasive particles by air washing. The air is then directed through a gravitating curtain of abrasive particles at a second cleaning location for further cleaning. The dust and debris laden air is then passed through a cyclonic separator and filtering system to clean the air prior to atmospheric discharge. Variously sized blasting head assemblies can be interchangeably mounted on the chassis for accomplishing various types of blast cleaning operations.
Abstract: The mechanism comprises a rotatable central shaft with pinion, racks engaging said pinion at two different levels and a change on the outside end of each rock for gripping the wheel, which clamps lie in the same plane.
Abstract: A supply apparatus for supplying a screw, a rivet, or the like includes a chute in which one edge portion of an upper opening of a guide slit formed therein is located inside a stock section or thereabove, so that screws in an abnormal position can be removed by a brush member not on the upper surface of an oscillating dipper but on the upper surface of the chute. A timing between oscillation of the dipper and movement of the brush member need not be controlled. Screws of abnormal position can be removed with a simple mechanism so as to supply only those of normal position to a predetermined position, and to reliably return removed screws of abnormal position into the stock section.
Abstract: A device for the mechanical stripping of electrical or optical cables has a stop for a fed-in conductor. The conductor is fixed in position by clamping jaws, whereupon its insulation can be severed by at least one rotating stripping blade. Disposed immediately next to each blade is a centering jaw, which centers the conductor. The jaw is radially movable relative to the blade so as to permit the penetration of the blade into the layer of insulation. The blades and the centering jaws are positioned axially and the desired cutting depth of each stripping operation is adjusted by spindles, each of which is operated by a motor which is controlled by a digital controller.

Abstract: A device for mounting and demounting tubeless tires with respect to wheel assemblies includes a wheel support structure upon which a tubeless tire and wheel assembly is positioned. An elongate vertically disposed mounting member is releasably locked to the wheel support structure and projects vertically upwardly therefrom through the tire and wheel assembly. A wheel clamping member projects through openings in the mounting member and is urged into clamping relation with the wheel by an adjustable threaded clamping bolt. An elongate lever has a tire removing member at one end thereof, which is insertable between the tire bead and the wheel rim so that, when the lever is maintained in engaging relation with the mounting member and is moved through an arc of 360 degrees, each tire bead will be successively removed from the wheel.
Abstract: The pliers form a cable wire testing tool. At the front end of a working portion (11a), a blade-type piercing member (18) is adapted to leave, in closed condition of the pliers, a free space relative to a surface of the other leg (12) serving as an abutment (17). In use, a cable wire is placed between the working portion (11a, 12a) of the pliers. Upon compressing the legs, the piercing member (18) penetrates the cable sheathing to establish with its point the electric contact between the cable core and the pliers' leg (11) which is provided with a connecting member (20) for the connection of a test cable (22). Due to the cable wire testing pliers, the customary stripping and securing of terminals may be avoided for testing cable wires.

Abstract: A manually operated gear wrench having a fixed hand plate and a wrench plate rotatably mounted thereon. The wrench plate carries a ring gear which meshes with a pinion gear rotatably mounted on the hand plate. Studs adapted to selectively receive socketed handles and tools are connected to the pinion gear and wrench plate. By connecting an operating handle to the pinion stud and a tool to the wrench plate stud, an input to output ratio of 3:1 is obtained. By connecting the operating handle to the wrench plate stud and the socketed tool to the pinion stud, an input to output ratio of 1:3 is obtained. A releasable locking mechanism is provided between the hand plate and pinion gear to prevent relative rotation between the pinion gear and ring gear to thereby provide an input to output ratio of 1:1.
Abstract: The invention pertains to a high production tire inflator apparatus for rapidly inflating tubeless tires wherein sealing between the tires and the wheels occurs at the tire beads. A tandem expansible chamber motor unit utilizing compressed air and hydraulic pressurized fluid vertically translates a carriage upon which an annular tire seal is mounted for displacement between tire indexing, sidewall displacement and bead seating positions, compressed air being used to displace the tire seal during rapid transverse movement, and the hydraulic fluid motor being employed to lock the tire seal to resist inflation pressures during pressurization of the apparatus. The wheel and tire are mounted upon a conveyor pallet which is of such configuration to directly sealingly engage the lower tire sidewall, and during inflation all sealing occurs between the tire sidewalls and the inflation apparatus, and no sealing of the wheel rim is required.

Abstract: A pipe wrenching tool adapted to be powered by a hand held power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversely to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted at both sides to have the drive source attached at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate with respect to the pipe.
