Publication number: 20140166624Abstract: A method and apparatus for sterilizing and destroying a syringe needle includes a rotating needle carriage that receives a needle in a loading position. The needle carriage includes a port sized to accept a pen-type hypodermic syringe and an insert to downsize the port for accepting a conventional hypodermic syringe. The needle carriage is rotated downwardly to a cut-off position. At the cut-off position, two opposing contact blades pinch the needle, which electrically connects the positive and negative terminals of a battery. Current flows through the contact blades to shear the needle. The sheared portion of the needle then falls into a waste compartment in the bottom of the apparatus. When the syringe is removed from the needle carriage, the needle carriage rotates upwardly and returns to the loading position.Type: ApplicationFiled: December 13, 2012Publication date: June 19, 2014Applicant: Q Care International LLCInventor: William F.

The device includes a base secured to the work support table of the saw and extending away from the saw blade. An arm is mounted at the end of the base, remote from the blade, and is spaced above the base. Also included are means with the arm for movably mounting a trammel point which engages and holds the center of the arc to be cut either on the work piece itself or on a holder therefor to determine the radius of the arc, as well as manual and power means for rotating the work piece about the trammel point.Type: GrantFiled: May 12, 1976Date of Patent: February 21, 1978Inventor: Rouchdy B. Raphael

Patent number: 4047458Abstract: A guide plate assembly, mountable on the table of a saw which guides a sheet rotatably fixed to the guide plate to enable the saw blade to cut the sheet into a circular disk of a desired diameter. The assembly includes a first slide bar that may be latched in position in a miter slot of the saw table, with a plate attachable to the first slide bar that is slidably latched to the first slide bar, and a second slide bar fitted with one or more cylindrical pivot holes which is also slidably latched in an open slot of the plate. A pivot screw, in the form of a wood screw fitted with a cylindrical head is fastened to the center of a sheet, to be cut, and the cylindrical head rotatably mounted in a pivot hole of the second slide bar, so that the sheet may be circularly rotated about the cutting edge of the saw blade.Type: GrantFiled: June 29, 1976Date of Patent: September 13, 1977Assignee: The Raymond Lee Organization, Inc.Inventor: Lester W. Hall

Patent number: 4027566Abstract: A horizontal base including a plurality of side by side horizontally spaced apart parallel guides is provided and a follower is selectively removably engageable with any one of the guides for guided movement therealong. A workpiece support is rotatably supported from the follower for angular displacement about an upstanding axis substantially normal to the plane containing the guides and the base is stationarily positionable on the horizontal table of a band saw or jig saw and a workpiece to have a constant radius arcuate cut made therein may be supported from the workpiece support and angularly displaced therewith in order that the blade of the saw may make the desired arcuate cut. The spacing of the parallel guide with which the follower is guidingly engaged from the blade of the saw determines the radius of curvature of the arcuate cut to be made.Type: GrantFiled: May 13, 1976Date of Patent: June 7, 1977Inventor: Thomas D. Harrill

Patent number: 4024782Abstract: An apparatus is disclosed for splicing the trailing end of an expiring web of an old stock roll to the leading web end of a new stock roll. The new stock roll is provided with a splicing tape for initially releasably attaching the leading end of the new stock roll to its outer web convolution. A plurality of sensors are provided for positioning the new stock roll and splicing tape in a precise presplicing position prior to the splicing operation. During the splicing operation, a web guiding and severing mechanism guides the expiring web into engagement with the new stock roll, severs the expiring web, and splices the trailing end of the expiring web to the splicing tape on the leading end of the new stock roll.Type: GrantFiled: June 27, 1975Date of Patent: May 24, 1977Assignee: Eastman Kodak CompanyInventors: Martin W. Kron, Victor I. Polz

Patent number: 3951023Abstract: Apparatus for feeding a continuous web of photosensitive paper into a reprographic machine so that the leading edges of the paper and a transparent master sheet to be copied are coincident as they enter exposure and developing stations, and to ensure that the tail end of the paper is cut, during continuous forward movement of the leading edge, so that the trailing edge of the severed paper coincides with the tail end of the master sheet. The feed path of the paper includes a curved portion defined by an arcuate-section guide and a concentrically mounted roller. A loop of paper is formed by moving the roller out of the guide and the rear end of the paper is then held stationary and cut by a guillotine while the paper forming the loop is continuously fed forward. The timing of the feeding and cutting operations on the paper is controlled by micro-switches actuated by the leading and trailing ends of the master sheet.Type: GrantFiled: June 11, 1973Date of Patent: April 20, 1976Assignee: Harper & Tunstall LimitedInventor: Adi Kaikhushiroo Ashburner
