  • Patent number: 4813316
    Abstract: A food product slicer includes a rotating blade and a carriage for supporting the food product. The carriage is mounted for lateral motion along a linear path to bring the food product into contact with the blade. A drive motor is selectively connected to the carriage for movement of the carriage along the path. In accordance with a method of automatically operating the slicer, the carriage is moved along the path by the motor to a predefined reference position nearest the operator. A motor position count is initialized, and during all motor energization, a count is generated corresponding to incremental movement of the carriage along its path. The motor is energized for a count to move the carraige to a position corresponding to a start of a slicing stroke. The motor is then energized for a count sufficient to move the carriage to a second position corresponding to a completion end of the slicing stroke.

  • Patent number: 4809787
    Abstract: An ice breaking attachment for impact hammers. The main component is a rigid metal beam used to transfer the blows of the impact hammer to the ice surface and then when the beam breaks through the ice distribute the impact of those blows over a large enough area to prevent damaging the underlying surface. The beam has a convex lower edge that also helps prevent damage to the underlying pavement. A vertical metal sleeve welded at the center of the beam accepts the blunt end of the impact hammer bit, and tether cables or chains attach the apparatus to the frame of the impact hammer.

  • Patent number: 4809789
    Abstract: A finned impact-operated boring tool according to the invention has an elongated body with a frontally tapered nose which merged with a generally cylindrical housing. A circular array of fins project radially from the housing along the surface thereof rearwardly of the nose of the tool and near the juncture of the nose with the housing. Each fin is generally rectilinear, and the fins are spaced apart to define a series of grooves therebetween which extend in the lengthwise direction of the tool. The distance from the bottoms of these grooves to the lengthwise axis of the tool housing is greater than or equal to the distance from the tool axis to the outer surface of the housing. According to one embodiment of the invention, the fins are formed on a replaceable collar which fits over the node of the tool. The finned boring tool according to the invention has improved movement speed through the ground.

  • Patent number: 4807362
    Abstract: The present invention is a hidden belt weapon which, by means of a simple twisting motion on the part of its wearer, detaches from a belt and simultaneously deploys to a "throwing-star" or "Ninja star" configuration. The operative belt-fastening means (the buckle proper) need not detach with the weapon. More particularly, the hidden belt weapon comprises a backing within which is mounted a central rotating member. A plurality of knife blades are rotatably attached to the periphery of the central rotating member by means of a plurality of blade deployment pins. When the central rotating member and the knife blades are in their collapsed configuration, the member and blades are concealed by the cover. Concealment of the blades by the cover enables the user to carry the weapon in a highly-accessible position on the body, such as over the belt buckle, without detection of the weapon.

  • Patent number: 4807365
    Abstract: A method for making the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape, in which a shear foil is mounted in an arcuate condition in a shaving-head frame without the cutter so that the foil assumes a free clamping curvature which is not influenced by the cutter, a normal-pressure distribution is applied perpendicular to the foil curvature which simulates the pressure distribution between the cutter and the foil in conformity with a desired effective shaving area, so that the shear foil experiences in said effective shaving area a deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponding to the desired normal-pressure distribution on the cutter in the desired effective shaving area relative to the shear foil.

  • Patent number: 4805823
    Abstract: A guiding pocket for driving staples is described, in which a first set of parallel sides helps form the opening for the guiding pockets. These parallel sides are connected to tapered sides, which are in turn connected to a second pair of parallel sides, creating a hexagonal shaped pocket. The resultant pocket configuration possesses self-centering features, which in turn reduces jamming and misformed staples and allows for simpler manufacturing and inspection.

  • Patent number: 4802395
    Abstract: A knife assembly for a net dispensing apparatus used on a round baler is disclosed wherein the knife assembly is moved into a cutting position engageable with the netting material without imparting impact energy into the netting material. The knife assembly includes a knife holder having a curved portion wrapped concentrically around a pivot shaft and a detachable knife member. When the knife assembly is moved into a cutting position, the netting material forms an angle around the cutting edge of the knife member with a portion of the netting material extending generally parallel to the plane of the plane of the knife member. The tension applied to the netting material by reason of the net dispenser feed roll being halted and the cylindrical bale continuing in rotation pulls the netting material across the cutting edge of the knife member to effect a severance thereof.
