Abstract: An economical apparatus and method for reprocessing scrap film. The apparatus includes a film-air separation chamber for separating air from incoming strips of scrap film, a cutter for cutting the strips into fine pieces, and a storage tank or further reprocessing means to which the cut pieces of scrap film are conveyed. A air bypass line having a computer-controlled valve conveys air directly from the film-air separation chamber to the cutter outlet when the valve is in an open position, and causes all of the air to flow into the cutter inlet when the valve is in a closed position. The open or closed position of the air bypass valve depends upon the cutter motor power, which varies as the volume of scrap film in the cutter varies. Due to the inclusion of the accurately controlled air bypass valve, only a single fan is needed to convey the film into and out of both the film-air separation chamber and the cutter.

Abstract: The invention concerns equipment for continuous chopping of municipal refuse and other solid wastes in general, consisting of: Section I: refuse collection subsystem, first compaction and conveyance to chopping section; Section II: subsystem for final compaction and chopping ribbon of refuse; Section III: subsystem for collection of chopped refuse and conveyance to landfill sites; Section IV: subsystem for collection and disposal of wastewaters. The equipment permits a ten-to fifteen-fold reduction in the initial volume of the refuse, together with a chopping operation which allows this volume to be maintained and to obtain refuse of a sufficiently uniform size prior to transportation or to disposal in landfill sites.

Abstract: A mechanical device to be used for removing coconut meat from coconut shell consisting of a serrated edge and a clamping device that will be attached to a stationary flat surface and will hold the tool in an upright position. The serrated edge will be used to grind coconut meat away from coconut shell, one half shell at a time.

Abstract: The invention relates to a machine for compacting and/or crushing bulk material, in which two rollers which can be pressed together at high pressure each consist of a main roller body and a roller shell which is releasably connected to the main roller body and is composed of individual segments. Each of the individual segments has one single lug projecting in the circumferential direction on the front long side in the direction of rotation of the roller and one single complementary recess on the rear long side in the direction of rotation of the roller. The generatrices of the outer surfaces of the segments point in the circumferential direction and run radially with respect to the roller axis. This results in a simple construction of the segments and a high degree of security against tilting.

Abstract: An improved centrifugal impactor for crushing rocks includes a hollow housing having a peripheral crushing chamber and a rotor mounted in the housing for rotation relative thereto about a generally vertical axis and spaced radially inwardly from the crushing chamber so as to define an annular passage for communicating a flow of rocks from an upper inlet opening and the crushing chamber to a lower outlet opening. The rotor includes a horizontal platform and a pair of outer and inner annular vertical barrier members attached to and extending upwardly from the horizontal platform. The outer barrier member is disposed about a peripheral edge of the horizontal platform.

Abstract: A method and apparatus for inserting fasteners which are press fit through aligned apertures in side-by-side workpieces. The apparatus includes a frame which is moveable relative to the side-by-side workpieces, the frame including a main frame and a subframe mounted on the main frame and moveable between the first and second positions. The subframe carrys tooling in the form of a drill and an upper ram. Also, mounted on the main frame are upper and lower spaced apart clamps which may be selectively moved into contact with upper and lower surfaces of upper and lower workpieces. The upper ram can be moved into contact with a headed fastener to force the shank of the fastener through aligned apertures drilled in the workpieces.

Abstract: An improved method and joint structure are provided for assembling a self-clinching fastener to sheet material, particularly thin sheet metal, in which an aperture and a peripheral flange are formed in the sheet metal; thereafter the shank portion of the fastener is inserted into the flange followed by clinching the fastener to the flange to secure the assembly. The sheet metal aperture and peripheral flange can be fabricated in a single work station in which the fabricating tooling punches the sheet metal aperture and extrudes or shapes the peripheral flange between a pair of forming dies. Assembly of the fastener joint with the flanged metal is performed in a second work station in which the fastener shank is inserted into the flange and then the head portion of the fastener is driven into the flange material to begin the clinching step.
