Patent number: 7150845Abstract: A method and molding tool for the molding of both one- or multi-component parts preferably comprising plastic material which may be integrated together with parts of another material, such as steel and copper, where the turnable middle section during the molding process is supplied with material on at least one of the surfaces thereof, that in contrast to the normal procedures are not at a right angle to the closing direction between the stationary mold part and the movable mold part of the tool. This can be realized by molding a part or a piece of a part and/or by molding around a special part for the in-molding on at least one of these surfaces of the turnable middle section. This molding and/or insertion can take place while the tool is closed and can be performed on several surfaces at the same time in order to save cycle time.Type: GrantFiled: May 15, 2000Date of Patent: December 19, 2006Inventor: Jes Tougaard Gram

Patent number: 7138081Abstract: A method for fabricating a seal-integrated separator for a fuel cell is presented, with which seals can be accurately positioned and the assembling time for the fuel cells may be greatly reduced. The method comprises the steps of: providing an upper mold having a groove positioned corresponding to second and fourth seals disposed on one side of a separator body, and a lower mold having a groove positioned corresponding to first and third seals disposed on the other side of the separator body; holding the separator body between the upper mold and the lower mold; and injecting melted seal material to form the seals into each of the grooves in the upper mold and the lower mold through separate gates respectively formed in the upper and lower molds. Through this method, a seal-integrated separator having the first to fourth seals which are integrated on both sides of the separator body is fabricated.Type: GrantFiled: November 30, 2001Date of Patent: November 21, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masajirou Inoue, Toshihiko Suenaga, Nobuaki Kimura, Keisuke Andou

Patent number: 7128860Abstract: The invention relates to the production of composite insulators consisting of a shank in the form of a bar or a tube, which is provided with a covering and which comprises plate-like screens which are distanced from each other. The covering and the screens are made of an elastomer material with high insulating qualities. As a result, the number, distance, form and size of the screens can vary from insulator to insulator. According to the invention, at least one injection mould (10a, 10b, 11a, 11b, 12a, 12b, 13a, 13b) for injecting a screen (2, 3, 4, 5, 19, 20, 21, 22) is arranged downstream from a device which is used to provide the shank (1) with a covering. The injection mould can be advanced in order to inject a screen upon the shank and opened in order to unmould said screen. An advancing device is also provided in order to displace (16) the shank (1) or the screen mould.Type: GrantFiled: October 12, 2001Date of Patent: October 31, 2006Assignee: Lapp Insulator GmbH & Co. KG.Inventors: Rene Mainardis, Michael Braune

Patent number: 7105116Abstract: A non-rotating anatomical-shaped breast implant having a front side with a smooth surface and a rear side with a textured surface. A smooth surface ripples or wrinkles little, if at all. Rippling or wrinkling of the implant may undesirably produce a visible or palpable waviness on the skin of the breast. A smooth surface is more likely to produce the look and feel of a natural breast. A rear side with a textured surface is desirable because tissue growth of the body, after the implant has been implanted, engages the textured surface to anchor the implant in place such that the front side with the smooth surface remains matched with the front side of the body and such that the anatomical-shaped breast implant with its tear drop shaped fullness remains at a natural position within the breast. The disclosure further includes a method for minimizing the rotation of an implant within the body and a method for making an implant envelope that has different thicknesses.Type: GrantFiled: June 16, 2003Date of Patent: September 12, 2006Inventors: Howard T. Bellin, Kenneth C. Kredovski, Ruairidh W. Campbell

Patent number: 7081223Abstract: A valve for controlling the flow of a gas therethrough which requires no machining in order to attain an effective seal between the valve seating surface and a rotatable plug element. The valve seat surface remains as cast while the plug consists of an overmolded plastic. The overmolding defines an array of pliable sealing ridges. The use of overmolding facilitates the use of cost-saving plastic materials, and obviates the need for expensive machining of the cooperating surfaces.Type: GrantFiled: November 19, 2003Date of Patent: July 25, 2006Assignee: Robertshaw Controls CompanyInventor: David Khoury

Patent number: 7070725Abstract: A method (10) includes the steps of placing an insert (12) into a mold cavity (20), molding an insulating layer (30) of a homogeneous and continuous composition (28) over the insert (12). The next step includes placing the insert (12) with the insulating layer (30) into a second mold cavity (36) followed by the step of molding the part (46) of a homogeneous part composition (44) over the insert (12). The insulating layer (30) is disposed between the insert (12) and the part (46) and bonded thereto. The method (10) includes painting the part (46) wherein a paint (48) is injected into the second mold cavity (32) over the part composition (44). Flexible properties of the insulating layer (30) adapt to the differences between coefficient of thermal expansion of the part (46) and the insert (12) thereby eliminating problems of potential cracks, sink-marks, and the like.Type: GrantFiled: June 25, 2003Date of Patent: July 4, 2006Assignee: Mathson IndustriesInventors: Boney A. Mathew, Ernest John Socha

Patent number: 7041245Abstract: A method of making a golf ball having a core and polyurethane including the following steps. A first portion of polyurethane is placed in a first cavity, and the first portion of polyurethane is allowed to partially cure to a selected state of gel. The core is positioned within the cavity while the core is vertically and laterally centered within the cavity. A second portion of polyurethane is placed in a second cavity at a time subsequent to placing the first portion of polyurethane in the first cavity. The second portion of polyurethane is allowed to partially cure, and the first and second cavities are mated together to cure the polyurethane around the core.Type: GrantFiled: January 14, 2000Date of Patent: May 9, 2006Assignee: Acushnet CompanyInventors: John Calabria, Dean A. Snell, Shenshen Wu

Patent number: 7029265Abstract: An apparatus for the continuous and nondestructive production of plastic panels which are provided with undercut anchoring studs, web profiles or other forms of attachment (28) on one or both surfaces comprises a temperature-controlled chill roll (11), which has peripheral cooling bores (15) in the roll body (17). The roll body (17) is formed at the circumference as a polygon with flat supporting surfaces (25), against which the molding/demolding strips (13) are placed or from which they are lifted. The molding/demolding strips (13) are moved by means of piston/cylinder arrangements (16) and piston rods (18). The piston rods (18) move through transverse bores through the roll body (17). The melt is filled into molds (27) of the molding/demolding strips (13) by the counterpressure between the shaping roll (11) and a counterroll (10) and is cooled down. During the filling of the molds (27), the molding/demolding strips (13) are pressed against the flat faces of the roll body (17).Type: GrantFiled: December 3, 2003Date of Patent: April 18, 2006Assignee: Alois Gruber GmbHInventor: Alfred Plammer
