Abstract: A base carries a tool head having two bore containing members that are relatively rotatable with respect to each other on a common axis of rotation. The bore portions contained in the two members are offset from the common axis of rotation by no more than one bore diameter. The two portions of the bore align in one relative position of rotation, but a handle is connected to at least one member to move at least that member to a position in which the bore portions are partially misaligned, severing any rod placed in the common bore by a combination of offset shearing action and rotary wringing action.

Abstract: A vacuum system for removal of debris in the form of shavings, particles, or the like has been developed for use inside of a cryostat to evacuate and collect such material as it is generated during specimen preparation using a microtome, also inside of the cryostat. The system includes a vacuum assembly unit containing a vacuum collection nozzle having a suction duct. The cold assembly unit is moveably positioned adjacent to the microtome knife so that debris is suctioned away and removed concurrent with or immediately after its production during cryotomy, and is captured in a cold primary filter. The frozen debris does not melt, but remains rigid while it freeze-dries and is trapped on the filter as cold air flows over and through it, thereby maintaining the collected waste material in a very porous state.

Abstract: A transportable facility for recycling waste plastics comprises at least one chipper, one storage hopper, and one extruder connected by constant-operation conveyors and integrated into components that are ready to either operate or move to another site. The components can be combined into an enclosed and modular production plant.

Abstract: A hole puncher formed as one piece of plastic molded into base, handle and receptacle portions hinged together by flexible, foldable joints. The one-piece plastic construction can be assembled quickly as a hole puncher by folding the portions into predetermined positions. A feature of the hole puncher is the use of a plastic locking strap connecting the handle and the base, for maintaining the handle folded over the base. Another feature is the use of translucent plastic material, enabling the user to visually check the desired alignment of pins with the paper to be punched, to assure proper location of the punched holes. The design provides an attractive, affordable and easily assembled design without sacrificing strength and durability.

Abstract: A die press unloader which retrieves material from beneath the lower die of a pair of dies mounted in a die press. The material which is retrieved will have passed through the lower die, and can comprise either scrap, for example in making perforated strip or product, for example in making shaped blanks from a strip. The unloader utilizes a combination of gravity and a mechanical arm, preferably actuated by a double-acting air cylinder, the movements of which are controlled by the press itself.

Abstract: A slicing machine has a housing, a rotatable blade on the housing having an edge defining a blade plane, and an input table on the housing displaceable parallel to the plane past the blade edge and having a holder adapted to hold a foodstuff to be sliced by the blade. The foodstuff is movable from a starting position by the table and holder toward the blade to slice the foodstuff. An abutment plate on the housing is displaceable between a shield position lying generally on the blade plane and a retracted position offset away from the table from the blade plane. An actuator connected between the housing and the plate sets the plate in its positions. A sensor generates an output when the foodstuff is moved out of the starting position. A control unit connected between the sensor and the actuator displaces the plate out of the shield position when the output is generated.

Abstract: A power take-off system for attachment to the elongated bar of a chain saw. A shaft is rotatably carried by a housing which is attached to the bar of the chain saw. A gear is carried on the shaft and is located in a transverse aperture in the bar such that the gear is driven by the nose sprocket in the bar. The housing serves as a guard over the chain on the bar also. The power take-off system may be provided as a self-contained integral unit which replaces the existing cutting bar on the chain saw.

Abstract: An apparatus for shredding debris from lawns and trees, such as twigs, leaves and like material has a housing in which a rotor is rotatably mounted about an upright axis. The plane of the rotor is thus generally horizontal and supported on a frame which permits movement across the ground. A vertical shaft engine is mounted on the upper side of the housing and supports the rotor within the housing cavity. The rotor has blades which generate an air flow as the rotor is rotating, to provide a vacuum in the center portions of the rotor. The vacuum draws material through a central opening in the bottom of the housing, and the blades impel the material outwardly toward pivotally mounted shredder blades at the outer periphery of the rotor. The rotor also mounts chipper blades in an upper surface thereof with an upwardly extending guide chute receiving limbs and guiding such limbs into the path of the chipper blades as the rotor is rotated, to chip branches, limbs and the like.

Abstract: A tire cutting machine that cuts the sidewalls from passenger car tires. The cutting operation is performed on both sidewalls simultaneously. The inner side of the tire tread rests on two rollers so that the tread becomes the reference point for the cutting blades. The tire tread is brought into contact with a drive wheel positioned on the outside of the tire tread and opposite one of the rollers on the inner side of the tire tread. The drive wheel causes the tire to rotate in a vertical plane. Two cutting blades (one on each side of the tire) are brought into contact with the sidewalls to sever them from the tread. As the cutting blades move towards the sidewalls, guide rollers move in unison with the cutting blades to center the tire between the blades and keep the tire centered as the sidewalls are cut.

Abstract: An apparatus and method for slicing food products such as loaves of bread and the like where multiple slices are formed at substantially the same time. A blade cleaning assembly is included for removing slicing debris from band slicing blades after having moved through the product being sliced. Multiple blade continuous cleaning by opposed scraper blades through which each band blade passes achieve the desired cleaning function. The apparatus and method are particularly well-suited for removing slicing debris from loaves of bread which are of the so-called no-fat or low-fat variety.

Abstract: A piercing die including a punch and a die cooperating with each other to effect a piercing operation on a metallic workpiece sheet, the punch having an outer peripheral edge having a closed profile at a working end thereof. The outer peripheral edge of the punch has a first and a second chamfered portion which are formed such that the amount of chamfer of the first chamfered portion is larger than that of the second chamfered portion. The first and second chamfered portions are formed along large-curvature and small-curvature portions of the closed profile of the punch, respectively, and/or along acute and obtuse outer peripheral portions of the punch whose working end face is inclined with respect to the direction perpendicular to the piercing direction. A piercing method using the punch and die is also included.

Abstract: A device which trims off the perforated margin strips of printer paper and cuts the paper transversely to separate it into individual pages. The paper which discharges from the printer is drawn around a tension bar and is applied to a toothed belt driven by feed wheels. Cutter wheels act against a grooved roller to cut along the tear lines of the margin strips. A photocell based counting system counts the perforations which pass the photocell to indicate each time the paper is advanced to position one of the transverse fold lines at a cutting station. Then, the paper is stopped and a cutter wire is pulled through the fold line to separate the leading page from the rest of the paper sheet. Each time a new sheet of paper is loaded, a special control circuit assures that the initial advance of the sheet stops with the leading edge of the paper at the cutting station.

Abstract: A vertically moveable upper receiver is suspended on the machine by spring means and has a central vertical cavity therethrough. A pair of opposed springs bias together jaws in the receiver having aligned notches therein which receive the part. The upper tool or punch descends through the cavity, engages the part, drives it out of its notches and downward against the inward pressure of the jaws, the receiver descending through this operation, and the part arrives precisely centered at the setting locus.

Abstract: A planetary ball mill in which a plurality of mill pots revolve by receiving a rotational force from a main shaft, while rotating on their own axes. A feed is continuously supplied to the mill pots so that ground particles are discharged out of the mill pots utilizing air flow. A partition for dividing a grinding chamber from a discharge pipe is disposed on the discharge side of the chamber of each mill pot so as to permit only the feed already ground to pass through. The feed having passed through the partition is collected by way of a discharge chute not rotating but surrounding a discharge pipe which rotates relative to the discharge chute to generate a negative pressure which assists the discharge of ground feed from each mill pot.
