Abstract: A method and apparatus for splitting logs, comprising an engine or prime mover actuating a reciprocating trolley through mechanical linkages along a fixed bed such that the trolley may urge a log to be split against a blade or wedge with mechanically amplified force sufficient to accomplish the splitting but may be instantly reversed and withdrawn to starting position at a rate of speed substantially higher than the speed of the splitting stroke as a result of differing mechanical advantages of the forward and reverse mechanical linkages.

Abstract: Apparatus for cutting and removing layers of photoresist overlaying tooling holes in a printed wire board blank. A lower cutter is mounted on a base so that its cutting edge projects above the upper surface of the base a distance substantially equal to the thickness of a layer of photoresist. A cutter head is mounted on the base for movement parallel to the upper surface of the base. An upper cutter is mounted on the cutter head for movement by a cutter actuator to cause the upper and lower cutters to sever segments of layers of photoresist overlaying a tooling hole of a PWB blank positioned between them. Each cutter is provided with a plunger movable within their respective cutters. The upper surface of the lower plunger, when the lower plunger is retracted, projects above the lower cutting edge of the lower cutter; and the upper plunger is biased downwardly so that its bottom surface projects below the cutting edges of the upper cutter.

Abstract: A tree cutting device comprises two opposed curved knife blades, each defining a portion of a surface of revolution. Swingable arms for the curved knife blades are journalled on separate shafts which are arranged with their axes in a common plane inclined relative to the center line of the trees to be cut. The separate shafts are arranged at an angle to each other so that their axes intersect at a point between the journalling means for the arms and the intersection between the common plane for the axes of the shafts and the center line of the maximum diameter tree to be cut. Preferably, each knife blade defines a portion of a sphere. To assure proper guidance of the knives, the knife edge of each blade is located unsymmetrically relative to the thickness of the blade.

Abstract: The device includes a fixed separating member with two mutually parallel thread guide plates spaced from one another and a cutting body movable toward the fixed member and operable by a textile machine. The cutting body includes two clamping shanks, which in the course of a cutting motion slide against the outer surfaces of the guide plates with a predetermined contact pressure in order to tension a thread guided crosswise over the guide plates. The cutting body also includes a blade so arranged between and parallel to the clamping shanks that in the direction of the cutting motion its cutting edge lies behind the clamping edges of the clamping shanks.

Abstract: A shear for cutting sheet material which functions by pivoting a specially constructed pointed blade about an axis by means of an arm so that the blade pierces into and then cuts the sheet is described as well as the method for its use. The blade is constructed such that it has double cutting edges forming a point wherein the cutting edge towards the pivot axis for the arm is concave and forms the point with the other cutting edge in a shape which approximates a shark's tooth. The blade pierces the sheet when the arm is pivoted towards the sheet and then cuts outward along a square edged surface on a frame supporting the arm away from the place where the sheet was pierced by the point. The shear is particularly adapted for the hand cutting of U shaped building channel to a predetermined length.

Abstract: A table for a saw has three equal table segments supported on foldable legs. The three segments are spaced from one another by spacer elements and held in position by front and back longitudinal rails and nut and bolt combinations through the spacer elements. The spacer elements hold the table segments spaced from one another thereby defining first and second lateral slots within which the rail of a mitre gauge can ride. Four spacer elements are integral parts of a spacer bar. Each spacer bar has laterally spaced spacer elements and vertically spaced spacer elements thereby providing numerous accurately dimensioned spacing locations between adjacent table segments. The spacer elements and longitudinal rails in combination establish table element positioning and rigidity with respect to one another as well as established two longitudinal slots having a uniform predetermined width.

Abstract: A method of producing stereoscopic film from standard 35 mm film is described in which the standard 35 mm is longitudinally cut in half. Selected sprocket holes in each half are enlarged to provide a series of locating holes at regular intervals along the film. Each locating hole enables a corresponding pair of stereoscopic film frames on the film to be located in a viewing position. Also described is a viewer for viewing the stereoscopic films. The viewer incorporates a locating finger which engages each locating hole in turn to locate and hold the film steady while viewing. The viewer includes a reciprocating drive means for driving the film. The locating finger is withdrawn from a locating hole when the drive means performs its forward stroke and the forward stroke is limited when the finger engages the next hole. The finger remains engaged with the next locating hole during the return stroke of the drive means thereby preventing any inadvertant movement of the film during the return stroke.
