Patent number: 4210042Abstract: A simple direct acting mechanism moves a circular rotatable disc cutter or two such cutters first to rollably engage a hard surface and then to traverse the surface to part the stock between a side-by-side pair of cords or wires. The cutter or cutters are blunt edged, as well as unheated and so avoid baring the cords or wires while parting the stock without the undesired effect of sharp or hot knives. The cutter or cutters are shiftable along the axis or axes to accommodate deviation of the cords with respect to the travel of the cutter. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.Type: GrantFiled: January 24, 1979Date of Patent: July 1, 1980Assignee: The Goodyear Tire & Rubber CompanyInventor: Gilbert A.

Patent number: 4173913Abstract: The cutter is primarily intended for use in cutting holes of various sizes in self-adhesive pads used by people who have had Ilyostomy and collostomy operations. It consists of a holder in the form of a hinged case for a square pad, a rotatable blade carrier, and a blade adjustably carried in a radial slot in the blade carrier. The blade carrier is formed in two parts having a snap engagement with each other, and the arrangement is such that on release of the two parts from each other all of the components may be separated for cleaning.Type: GrantFiled: March 8, 1978Date of Patent: November 13, 1979Inventor: Barrie F. Nicholson

Patent number: 4100828Abstract: A multicell battery case, adaptable for use with a variety of cell-pack sizes, is molded with universal-sized cell compartments and opposing spacer-ribs projecting a predetermined distance into the cell compartments from the compartments' walls so as to provide an inter-rib gap across the compartment substantially equal to the narrowest cell pack useful with that case. The case is thereafter adapted for use with thicker cell packs by trimming back the opposing ribs to increase the gap therebetween to approximately the thickness of the cell pack actually destined for use with that case. Preferably, rib-shaving blades are inserted into the case and guided in spaced relation from the rib-bearing walls to remove distal portions of the ribs. Means are provided to detach the shavings from the container at their roots.Type: GrantFiled: May 19, 1977Date of Patent: July 18, 1978Assignee: General Motors CorporationInventor: Robert H. Thune

Patent number: 4015496Abstract: A tube cutoff apparatus arranged to provide an improved cutoff of a tube avoiding dimpling of the tube. The apparatus includes an improved blade configuration and mechanism for moving the blade in different directions to effect a multistep tube cutoff. In a first step, the tube is chordally notched, and in a second step, the tube is diametrically sliced to provide a dimpleless cutoff.Type: GrantFiled: February 6, 1976Date of Patent: April 5, 1977Assignee: Hill Engineering, Inc.Inventor: Donald R.
