Patent number: 5507090Abstract: A method for making a plurality of stress sensors includes creation of cavities and corresponding diaphragms in a thin metal front plate, preferably by an acid etching process. A thin back plate, preferably comprising metal, is secured to the front plate over the cavities, preferably by welding. A plurality of strain gages is bonded to the diaphragms in the front plate with a layer of bonding agent such as epoxy. The bond layer is of substantially uniform thickness on at least that portion of the front plate where the diaphragms are located. As the bond layer cures, a magnetic force is applied to the diaphragms to reduce their movement toward the back plate, and to thereby assist in creating a bond layer of substantially uniform thickness near the diaphragms. A suitable magnetic force may be applied by positioning a rare earth magnet near the diaphragms. The magnetic force may be supplemented by a mechanical force.Type: GrantFiled: July 20, 1994Date of Patent: April 16, 1996Assignee: Thiokol CorporationInventors: John Shipley, Lloyd T.

Patent number: 4010524Abstract: There is disclosed a manufacture of a continuous hinge. The process is as follows. A metal strip is fed intermittently by a predetermined length towards a press-machining station where the strip is simultaneously cut and bent to form a hole, flap, swaged flap and loop during the stoppage of the strip. The strip having loops is cut into predetermined length to form leaves for a hinge. A pair of leaves are assembled by inserting a pintle through the aligned loops, and the assembly is reformed by roll means.Type: GrantFiled: November 6, 1975Date of Patent: March 8, 1977Inventors: Akashi Osamu, Nakamura Masazo

Patent number: 4004340Abstract: The slide frames consist of plastic material and are supplied ready for use. The film is fed in steps to a cutting device for severing the leading film section. The film section severed by the cutting device is gripped in the cutting station by a plierlike gripping device and in this position, without being pivotally moved through 180.degree., is inserted as far as possible for projection into the internal space of a frame, which is held ready in an expanded or unfolded position. The film section is held in this position for projection until the expanded or unfolded frame part is released. Two protective strips of transparent material, such as polycarbonate, are fed on respective sides of the film strip before the cutting device. The protective strips have for each feeding step at least one perforation hole, which is aligned with a perforation hole of the film strip. The two protective strips sandwiching the film strip are subjected to the same process steps as the film strip in unison therewith.Type: GrantFiled: December 18, 1974Date of Patent: January 25, 1977Assignee: Geimuplast Peter Mundt KGInventor: Otfried Urban

Patent number: 3998300Abstract: A drum brake shoe has a rim providing a lining support plate, the rim edges being formed with projections and recesses on either side of a center section. The width of the rim is substantially constant throughout the majority of its arcuate length. The arrangement permits the stamping of nested rim blanks, each blank extending transversely across a sheet, with approximately 25 percent less material used than would be the case if the rims were made of full constant width to support the entire brake lining. The brake lining is attached to the outer surface of the rim and is directly supported by the rim center section and the projections extending laterally therefrom. The lining is unsupported in the areas where it extends over the recesses. The projections and recesses may be generally rectangular or curvilinear.Type: GrantFiled: April 14, 1976Date of Patent: December 21, 1976Assignee: General Motors CorporationInventor: William M. Sullivan

Patent number: RE33606Abstract: A power transmitting belt manufacture wherein belts are molded to have various cross sections. The belts are machined to a desired cross section. Each belt is entrained about drive and driven pulleys to run the belt under a preselected tension. At least one roller is caused to engage the back surface of the driven belt to reinforce the otherwise unsupported belt at the point of cutting between drive and driven pulleys. A pair of opposed cutting blades are engaged with the opposite sides of the belt to form the opposite side edges of the final belt section.Type: GrantFiled: December 26, 1989Date of Patent: June 11, 1991Assignee: Mitsuboshi Belting Ltd.Inventors: Yoshihiko Kamiyama, Misao Fukuda, Akihiro Nagata
