Abstract: A shape sawing system for sawing lumber pieces from a curved cant. The cant is scanned by scanners and the scan data is input to a computer. The computer determines a curved path for the saw to follow in sawing the cant into lumber pieces. The saw is laterally and pivotally adjustable to follow the determined path established by the computer. The saw is a plurality of circular saw blades having a defined cutting edge portion that is inclined from a leading point at the bottom of the cant to a trailing point at the top of the cant. The point of pivot of the saws is between the leading point and the trailing point of the cutting edge portion. The saw assembly is mounted on pads having a low coefficient of friction. Pressurized air and lubricant are delivered to the pads to reduce the friction.

Abstract: A table saw for use in dismantling wood pallets is provided with a table and band saw blade having course over table to cut nails between face boards and stringers as pallet is moved through blade. Table has convex, arcuate fence about which pallet may be twisted to facilitate cutting of nails. Table is shiftable horizontally relative to the saw blade to adjust position for use by single operator with short pallets or two operators with long pallets.

Abstract: This invention applies to a shape sawing system for sawing lumber pieces from a curved cant portion. A scanner scans the cant portion as it is conveyed on a conveyor system and inputs the scan data into a computer. The computer determines the curvature and position of the cant portion on the conveyor system. The conveyor system conveys the cant portion through side chippers and into a saw. The side chippers are independently laterally adjustable to follow the curvature of the cant portion. Guide members mounted strategic to the saw guide the cant portion into the saw. The saw is pivotally and laterally adjustable to follow the curvature of the cant portion to produce full length and partial length lumber pieces from the cant portion.

Abstract: A cassette (10) for photosensitive web material includes a hollow housing (12) having a peripheral wall (16); an exit slit (42) extending through the peripheral wall; a device (20), located within the housing, for rotatably supporting a roll (22, 24) of web material; a mechanism (32, 38), located within the housing, for engaging a lead end (26) of a web material to drive the web material through the exit slit; a knife blade (134, 136) having a cutting edge (138) extended at an acute angle to the exit slit; a recess (132) for slidably mounting the blade for movement between a first position in which the exit slit is open, and a second position in which both the web material has been cut by the cutting edge and the exit slit has been closed by the blade to prevent entry of light into the housing through the exit slit; and a knife bed (142, 144) fixedly mounted on the housing, the blade being in sliding engagement with the knife bed, whereby the blade and the knife bed cooperate to scissor the web material as th

Abstract: Apparatus and method for cutting and dispensing of adversarial interaction countermeasures, as for example chaff dipole elements for the self-protection of aerial vehicles against radar-guided missiles, providing substantially instantaneous in-flight cutting and dispensing of chaff dipole elements into the airstream along the flight path of aircraft, helicopters, and other aerial vehicles. The device comprises a drive motor assembly having a flywheel providing a motor inertia enabling the motor to maintain a substantially constant rotational speed when a load is applied for cutting of the material to be dispensed. Countermeasure articles that may be advantageously be cut and dispensed into an adversarial interaction area by the means and method of the invention include dipole elements which are interactive with radiation of varying character, e.g., infrared, microwave, ultraviolet, millimeter wave, etc., as well as less-than-lethal (LTL) adversarial interaction countermeasures.

Abstract: A method and apparatus for accurately slitting a rod into two equal sections in which the rod is longitudinally advanced to a slitter and is laterally shifted by an in-line guide adjustment system or 1GA so that the slit sections will be equal. The rod sections are measured by the 1GA after slitting to evaluate any difference in size therebetween while the sections are advancing, and the 1GA transversely shifts the rod before it enters the slitter to eliminate any size differential between the slit sections.

Abstract: An apparatus for cutting and crimping pipe having a first jaw and a second jaw between which a pipe is placed to be crimped and/or cut. At least one of the first jaw and the second jaw is mounted for relative reciprocating movement toward and away from the other, whereby the jaws are capable of cutting and crimping pipe placed therebetween. A guide mechanism, preferably a guide plate, is disposed at an angle to the jaws for guiding a pipe placed between the jaws, whereby the pipe can be cut and crimped at an angle determined by the angle of the guide mechanism. It is preferable that the jaws have a first section provided with a mechanism for cutting and crimping pipe and a second section without a mechanism for cutting pipe whereby pipe placed in the second section may be crimped only. Preferably the first jaw is driven by a hydraulic ram.

Abstract: The trimming apparatus and fixture for holding a PC board prior to and during trimming of an upper surface of the PC board utilizes a trimming blade rotated by a variable speed motor. This apparatus includes X and Y motion mechanism moved by hand grips that are spaced apart and cooperate with push button switches providing a safety control circuit. The X and Y motion mechanism employs linear ball bushings mounted and movable on hardened steel shafts. Removable holding fixtures are employed to hold and retain the PC boards during trimming. One holding fixture is used for PC boards that are not warped and not likely to warp. This fixture holds the PC board on three sides and a quick acting cam clamp is actuated to retain and release a PC board. Another fixture is adapted to hold and retain a PC board that is warped or likely to warp. Vacuum is used with a plurality of standoffs to establish the desired holding plane of this PC board.

Abstract: Apparatus is disclosed for shuttling a workpiece to a work station in a forging press and rotating the workpiece about a vertical axis to orient different portions thereof relative to the work station. The apparatus includes a workpiece support mounted on a horizontally reciprocable shuttle plate for displacement therewith toward and away from the press and for displacement relative thereto about and along a vertical axis. A workpiece to be forged is positioned on the workpiece support while the shuttle plate is displaced from the press, and displacement of the shuttle plate toward the press positions a portion of the workpiece at the press work station. A pair of leveling units are mounted on the shuttle plate adjacent the workpiece support and are operable to support portions of the workpiece outside the work station during a forging operation.
