Patent number: 5005281Abstract: Complementary laminations for a stator pole assembly and a cooperating rotor pole assembly of an electric motor or generator are produced simultaneously from a plate of magnetic material. The plate is stamped to produce an outer peripheral edge corresponding in shape to the exterior of an annular stator yoke and to produce a central aperture shaped to be received by an indexing element of an indexing table. The plate is then repeatedly indexed about its center in equal angular increments and a punch is displaced in a reciprocating rectilinear fashion synchronized with the indexing to punch a multiplicity of identical apertures equally-spaced circumferentially. The apertures are shaped to define internal edge surfaces in the plate corresponding in shape to radially inner surface of the stator yoke and to radially outer surfaces of a central hub of the rotor pole assembly and to define a multiplicity of identical radial webs.Type: GrantFiled: August 20, 1990Date of Patent: April 9, 1991Assignee: Dynamics Systems International Inc.Inventor: William Burns

Patent number: 4999901Abstract: The invention provides a process of producing a nozzle member for sucking and transporting a string of yarn having an inner diameter which varies along an axial direction of the nozzle member. The process comprises the step of drawing a pipe stock having a predetermined outside profile so as to transfer the outside profile in an axial symmetrical relationship to an inside profile of the pipe stock. By the process, a nozzle member can be produced readily with a high degree of accuracy.Type: GrantFiled: June 8, 1990Date of Patent: March 19, 1991Assignee: Tsudakoma Kogyo Kabushiki KaishaInventors: Hidenobu Toratani, Tamio Moribe, Ryuuichi Takenaka, Tooru Nakagawa

Patent number: 4862574Abstract: Improvements are made in a panty protector of the kind comprising adhesive attachment and provided with transversely extending flaps. The peripheral shape of the protector is such that it is possible to produce the sheet of material of construction for the protector and simply cut said shapes out of said sheets with minimal waste.Type: GrantFiled: February 21, 1989Date of Patent: September 5, 1989Assignee: Personal Products CompanyInventor: Wassim Seidy

Patent number: 4832316Abstract: A method of forming a wall security fixture of the kind having an elongate rail and a plurality of upstanding palings connected to the rail. In the method, a flat sheet of material is punched to form a series of flat, intermediate paling members which are located side-by-side in complementary relationship. The individual intermediate members are then folded about an axis of symmetry to form V-shaped palings which have outwardly splayed end portions which can be welded or otherwise fixed to the web of a channel-shaped rail to secure the paling to the rail. The invention extends to wall security fixtures formed according to the method.Type: GrantFiled: May 4, 1987Date of Patent: May 23, 1989Inventor: William H. Mincher

Patent number: 4805289Abstract: An electric motor mount is achieved by first and second sheet metal pieces, the first piece being longer than that of the second and the first piece having a first and a second end, the second end being wider than that of the first end. The first and second pieces are stamped in sequence from a strip of sheet metal, and the first piece has a median transition portion forming a transition in width between the wider second end and the narrower first end. This median transition portion is complementary to a portion of the second piece, so that they are nested together, with no waste in the sheet metal strip. Each piece is bent at about right angles, and then the first ends are mounted to the motor at motor mounting apertures, and the second ends form mounting feet to be attached to a support for the motor and motor mount.Type: GrantFiled: June 10, 1988Date of Patent: February 21, 1989Inventor: Giles W. Morrill

Patent number: 4773147Abstract: A method of manufacturing blow molded plastic cases of the type comprising two hollow hinged containers where at least one of the containers has a compartment, and a door for the compartment is presented. The method allows the manufacture of compartment doors as part of an integrated manufacture without requiring a separate blow molding step to make the door. The method comprises blow molding a standard size door as one face of a first hollow container, in an area of the container which would otherwise be cut out and discarded, removing the door from the container, storing the door for future use, and assembling the first hollow container with a second blow molded hollow container to make a first case. A third and fourth hollow container are blow molded, and an area sized to accommodate the door stock is cut from the third container. The door is retrieved from stock and mounted in the third hollow container.Type: GrantFiled: August 18, 1987Date of Patent: September 27, 1988Assignee: The Plastic Forming Company, Inc.Inventor: Peter T. Schurman

Patent number: 4748838Abstract: A method for making a corrugated thin metal strip wherein corrugations are linear and extend obliquely from one longitudinal marginal edge to the opposite longitudinal marginal edge of the strip. The invention involves passing the thin metal strip through corrugating rolls for impressing a series of single apex, V-shaped chevron corrugations into the surface of the metal strip. The rolling of the strip between the helical gears is done in such a way that the apex of the V-shaped chevron is the last portion to leave the corrugating rolls whereby the apex is in tension and enables metal strip to be split into two obliquely corrugated metal strips along the apices of the chevron.Type: GrantFiled: May 18, 1987Date of Patent: June 7, 1988Assignee: W. R. Grace & Co.Inventor: Richard C. Cornelison

Patent number: RE38396Abstract: A method of making pairs of thread splits inserts used to injection mold bottle preforms. Machining a hollow outer part of the pair of thread split inserts with an opening therethrough and outer portions of two cooling conduits extending from the opening therethrough to respective inlets and outlets. Making an inner part of the pair of thread split inserts by injection molding a ceramic core with the required shape and investment casting the inner part around the ceramic core. The outer surface of the inner part having grooves to partially form inner portions of the two cooling fluid conduits. Then machining the cast inner part to fit in the opening through the outer part. Mounting the outer part around the inner part with the inner and outer portions of the two cooling fluid conduits aligned. Applying brazing material between the inner and outer parts and heating them in a vacuum furnace to integrally braze them together.Type: GrantFiled: August 3, 2001Date of Patent: January 27, 2004Inventor: Jobst Ulrich Gellert
