Abstract: A photographic film cassette manufacturing apparatus, has a perforator for providing a long film with perforations and a cutter for cutting the long film into individual filmstrips to be contained in the film cassette driven synchronously with transport of the long film. A magnetic recording head for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator and the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, a trailing end of the individual filmstrip in the first direction is moved in a direction which is reverse to the first direction to secure the trailing end to the spool. A cassette shell consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the position of flanges of the spool.

The outer annular flange further includes a plurality of arches formed therein.

Abstract: A wheel cover is formed to include a wrap around the circumference of the wheel cover. The wrap is an aesthetic portion of the wheel cover and not a part of a mechanical lock. It is formed in the wheel cover by spinning the wheel cover about its central axis. When the wheel cover is spinning at an appropriate speed, at least one pair of rollers is moved toward the spinning wheel cover. Lock generating rollers provide a force which is directed radially outwardly while wrap generating rollers provide a force which is directed radially inwardly. This force is of such a magnitude that it forces the outer edge of the wheel cover to follow the contour of the rollers. When the wrap is completely formed, the rollers are removed from engagement with the wheel cover and the wheel cover is stopped from spinning. Once the wheel cover is removed from the fixture of the spinning machine, it proceeds with further manufacturing steps to complete the manufacturing thereof before it is mounted to a wheel.

Abstract: Upper and lower mirror image die plates are resiliently supported and have predetermined displacement values for forming vortex generators and foldline crease channels without compressive deformation in a porous sintered metal fiber sheet material. Cutters and ridges coupled to the upper and lower die plates form the respective vortex generators and channels. The sheet of so formed material is then placed in an apparatus for bending the sheet at the foldline channels to corrugate the sheet without deformation of the sheet material between the corrugation bends. Fingers align with and engage the channels. The fingers are on plates that are ramped closer together simultaneously while the fingers on two mirror image coplanar sets of plates displace toward each other as the sheet material is folded. Pins on a pair of rotating levers engage each of the finger plates of the two sets for relatively horizontally displacing the plates and corresponding fingers as they are ramped together vertically.

Abstract: A method of connecting the free end of an elastomeric cord to the hook of a connector, that is attached to a loop on the other end of the cord, to form an endless drive belt to connect a pair of rotary drive members, which utilizes a novel tool. The tool has a retainer segment and a contact segment comprising a pair of curved contact arms flanking a finger and forming an opening, and a handle. The tool contact segments are placed on one of the rollers with the finger in the roller drive groove and the handle resting on an adjacent roller. The connector and attached cord end loop are placed in a retainer pocket on the finger. The cord free end is then grasped and pulled around both rollers, which clamps the tool to the roller, and onto the hook to form the endless belt. The handle is grasped to raise the tool, pivot it around the roller to unclamp the tool, and slide the tool to disengage it from the drive belt.

Abstract: The combination of a lawn mower assembly and a clamp assembly. The lawn mower assembly has a housing defining a cutting chamber, a shaft journalled for rotation in the housing around an axis, and a cutting blade that is selectively a) releasably attached to the shaft to rotate with the shaft in a predetermined path around the shaft axis and b) separable from the shaft as to facilitate reconditioning or replacement of the cutting blade. The clamp assembly includes a first jaw having a first surface and a second jaw having a second surface. The second jaw is movable relative to the first jaw between i) a first relative position wherein the first and second surfaces are spaced from each other a first distance and ii) a second relative position wherein the first and second surfaces are spaced from each other a second distance that is less than the first distance.

Abstract: Identical ring-shaped metal blanks are machined whereby each blank forms a plurality of identical components. The blanks are first machined on both sides, and then a stack of the blanks is clamped axially adjacent one another on an arbor. Tools machine the blanks for reshaping the blanks. One of the tools is a slitter which makes axial cuts through the stack to separate each blank into a plurality of components distributed around the axis.

Abstract: A method of manufacturing a wheel rim for a two-piece vehicle wheel assembly. The method includes the step of casting a one-piece alloy wheel form. The wheel form defines an integrally-formed annular rim blank and supporting center. The rim blank includes opposing first and second annular edge portions. The first annular edge portion of the rim blank is machined, and then the second annular edge portion of the rim blank is machined. After the machining steps, the one-piece wheel form is cut to separate the machined wheel rim from the supporting center.

Abstract: The invention relates to a method for assembling and disassembling an installation present on a seabed, for instance a pipeline lying on a seabed, wherein components, for instance pipe flanges, are mutually attached by means of nut and bolt connections and the nut and bolt connections are released and/or secured by means of a wrench. Nut and bolt connections are herein released by divers using a wrench. This is heavy and difficult work. It is impossible for divers to operate at considerable depth. Complicated and very costly pipeline connections are then applied which can be released and secured without divers. The invention has for its object to reduce the stated drawbacks of the known method. To this end at least one wrench is used, of which an engagement cup for engaging a nut and/or a bolt head in axial direction of a nut and bolt connection for manipulating is displaceable relative to a cup carrier counter to spring action.

Abstract: A rewind spring in a cassette for a seat belt retractor is assembled by first placing a mechanism cover on a winding jig. An arbor is fitted to a winding shaft of the jig. One end of a coiled metal bank spring is then fixed to the spring arbor. The band is then wound onto the arbor in the mechanism cover and a spring cover is fitted to the mechanism cover. Finally, a locking clip is attached to the spring cover to lock the arbor against rotation. A spring arbor for use in the cassette has a generally cylindrical shape and an axially extending slot for receiving an end of the spring. A step is provided in the profile of the cylindrical outer surface of the arbor in the region of the slot to compensate for the thickness of the band wound thereon.
