Abstract:
Apparatus for supporting a coaxial cable, or the like, and effecting cutting and stripping operations to remove a portion of one or more layers which concentrically cover a central conductor. A single blade, having a circular cutting edge, is moved in an orbital path about the cable with rotary motion of a motor translated to orbital motion of the blade through a plurality of plates relatively movable on crossed, linear, roller bearings and a shaft eccentrically affixed to the motor with the shaft and motor axes at an acute angle to one another. The shaft extends through a spherical bearing mounted in one of the plates, thereby translating nutational motion of the shaft to orbiting motion of the plate which is directly attached to the blade. A unique clamping assembly includes a pair of jaws having respective gear racks engaging a single pinion gear on a motor output shaft for linear movement of the jaws by equal distances in opposite directions. A microprocessor controls the level of current to the motor, thereby adjusting the clamping force applied to the cable, and increases this force during the stripping operation, when maximum axial force is applied to the cable. A guide bushing establishes the radial position of the cable axis and is stationary during blade movement, thereby permitting the opening in the bushing to closely approximate the cable diameter. The position of the bushing is adjustable to align the central axis of the bushing opening with that of the blade cutting edge. The bushing is also movable to an inoperative position to permit unobstructed access to the blade for replacement thereof. A pair of gripping members are movable to engage the severed portion of the covering layer to assist in the stripping operation, and a unique combination of hardware and software is provided for calibrating the position of the gripping members at equal distances from the axis of the cable.
Abstract:
A cutting/stripping apparatus, and methods of operation thereof, which include at least one first blade for rotary motion about the central axis of a multi-layered workpiece, and at least two, second members/blades reciprocally movable along essentially linear axes, toward and away from the one another while remaining equally spaced on opposite sides of the central axis. The general structure of the apparatus may be a single, orbiting blade to provide cutting of the outer layer about its entire periphery and a pair of members movable toward and away from one another to engage the outer layer. The pair of members may have linear, opposed edges, or may have a V-shaped or radiused (curved) cutting edges. Electronic controls and software, together with selective operator inputs which define operation of the apparatus, permit cutting the outer layer of the workpiece by either the rotary blade or the reciprocating blades.
Abstract:
First and second rotating units (110, 120) include a pair of rotors (111, 121) opposing each other, a spindle (113, 123) provided between the pair of rotors, and an impacting body (130, 140) mounted rotatably on the spindle (113, 123). The impacting body (130, 140) is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of a periphery of the impacting body can be positioned beyond a periphery of the rotor. The impacting bodies of the first and second rotating units impact on an object to be processed sequentially while the rotating units are rotated at a high speed, thereby cutting the object to be processed. A cutting depth by the impacting body of the second rotating unit is larger than that by the impacting body of the first rotating unit, and the impacting body of at least one of the rotating units impacts on the object to be processed at least at a critical impact velocity. This makes it possible to cut an object to be processed formed of a single material or a composite material using a single cutting tool and to extend the lifetime of a cutting device and improve the reliability thereof.
Abstract:
An apparatus for the simultaneous shearing of two sides of the boiling water nuclear reactor control rod. The rotation of the rods at 90 degree rotation and the shearing of the second two sides underwater in a nuclear waste storage pool.In a previous application by A. H. Krieg, Ser. No. 692,849, we have seen the crushing of a BWR control rod for the purpose of reducing nuclear radioactive waste. The control rod however has an end referred to as the velocity limiter end, which is round and bulbous. This end can not be crushed practically, due to its mass. The purpose of this invention is to shear or cut-off the velocity limiter from the rest of the control rod thus having the remaining cruciform crushable. Between the velocity limiter and the rest of the control rod are 2 "D" shaped holes, hereafter refered to as the "D" holes. At this point the control rod is solid and does not contain hollow fins or boron rods.The control rod can therefore be sheared at the "D" hole without concern of polluting the containment pool. At the bottom of the velocity limiter, in its center, is a protrusion which is cylindrical. This protrusion is allowed to stick into a hole in the turntable that rotates the velocity limiter in 90 degree increments for shearing and alignment. At the bottom of the velocity limiter are four ball or wheel like protrusions. These fit into slots in the turntable, and because they are in alignment with the fins, cause the correct positioning of the entire device for shearing. They act as the positioning stop for a rotating device that controls the turning of the control rod. In this manner, it is possible to index the control rod in such a way so that the shearing heads can be activated and carry out their designed function. After the first shearing operation is complete the shearing heads are retracted from the control rod to a sufficient distance to allow rotation. After completion of rotation, the shearing heads are returned to their working position.

A hand-operated dry wall taping machine includes an elongated tubular main body portion, to be held by the operator, with a tape applicator head at the end adjacent the seam being taped. A supply reel of tape is carried from the tubular body. The applicator head includes a dry wall cement dispenser box, through which the dry wall tape is fed. Cement is dispensed onto the side of the tape which is to face the wall being taped. A rotary tape shear is disposed up-tape from the cement dispensing box. A hand actuated pneumatically operated cylinder actuates the rotary shear at the end of the seam being taped and advances a short length of tape through the cement dispensing box in readiness to commence taping of the next seam.
Abstract:
Apparatus for cutting logs, such as tree trunks, into lengths comprising a frame, a pair of spaced substantially parallel shafts rotatably mounted on the frame, and a pair of blade members mounted on the shafts so that a log can be fed between the blades. The blades are rotated in relatively opposite directions so that during a log cutting stroke, the blades move toward each other and into a log therebetween so as to cut substantially entirely through the log. fluid actuated cylinder assembly drives the blades through the cutting stroke. The blades are configured so that they will follow the path of least resistance during cutting movement into a log and the apparatus is particularly adapted for inclusion in a tree harvesting machine which converts standing trees into logs of predetermined length.
