Abstract: A vent control system having a closed biased vent valve is used to separate vapor and/or air from a liquid in an enclosed chamber. The closed biased vent valve has a float having an upwardly extending float arm which cooperates with a lever arm of the closed biased vent valve to prevent unintended release of vapor or liquid from the enclosed chamber. The upwardly extending float arm and the lever arm are coupled to one another when the float is located beneath a designated level in the enclosed chamber and are decoupled from one another when the float rises above the designated level. The vent control system is much less susceptible to vibration induced vent opening than a traditional vent valve. The vent control system is well suited for use in a fuel vapor separator that includes a housing having the enclosed chamber formed within it.

Abstract: The tire of the invention incorporates an active nylon flipper in each bead region. The flipper is active in the sense that it actively absorbs differential shearing strains that arise between each turnup end of the ply and each rigid metal bead during heavy-duty service. In conjunction with each of the two flippers, a chipper protects the portion of the ply lying closest to the wheel rim when the tire is mounted. A nylon patch overlaps the respective end of each chipper, the turnup end of the ply, and the radially outermost part of each flipper. The shearing modulus of the nylon material of each flippers and each patch is intermediate between the shearing moduli of the adjacent materials, which thus distributes and absorbs shearing stresses in ways that reduce the tendency of the turnup ends and the radial most part of the chippers to separate from the adjacent tire structures during heavy-duty operation.

Abstract: A laminator comprises a pair of pressure rolls 2 having a substrate 1 and a film 55 sandwiched therebetween and bearings 3 adapted to rotatably support opposite end portions of the pressure rolls. One end of a lever 7 is attached to a housing of each bearing. The other end of the lever 7 extends in an axial direction of the pressure roll 2 and is located inward of the bearing 3.

A shaft 16 is disposed in spaced parallel relation to the pressure roll 2. Extension arms 17 are formed in the housings of the bearings 3. The extension arms 17 are connected to the shaft 16, to thereby enable the shaft 16 to support the bearings 3.

Abstract: The invention relates to a device and a method for fitting motor vehicle tires onto rims of disk wheels having a tire fitting tool (17) which can rotate about an axis and is mounted at a distance from the axis, an electric motor (2) as a drive motor for a rotational drive of the tire fitting tool (17) about the axis and a power supply device for the drive motor, the power supply device being connected to a gradient-limiting device which, when a predefined gradient of the torque transmitted from the drive motor (2) to the tire fitting tool (17) is exceeded, causes a braking current for stopping the rotational drive to be supplied to the drive motor (2). With the gradient as switch-off criterion, switching off takes place significantly before the limiting value of the torque or of the motor current is reached, so that the tire is handled more gently and it is ensured that the tire is not damaged by the interrupted fitting procedure.

The apparatus is designed to receive, generally by adhesive affixation, a display graphics screen such that generally the entire length of one of the screen edges is affixed to the apparatus, with the length of the screen edge and the apparatus generally equaling that of the corresponding display frame segment. Additionally, the screen mounting apparatus includes an elastic portion which permits a limited degree of resilient movement when force is placed upon the screen at assembly and disassembly. The tension force required to mount the apparatus and the affixed screen to a display frame is thus distributed along the entire surface of the apparatus and screen, and not at isolated fastening points.

Abstract: A reverse break stamp hook assembly and method for breaking a biscuit from a casting. The reverse break stamp hook assembly is mounted to an upper trim die of conventional stamping equipment, and includes a leg that hangs from a pivot attached to a mounting bracket and a counterweight arm that extends from the pivot. The hook includes an angled front portion and a catch portion. As the upper trim die moves toward a lower trim die during the downstroke, the angled front portion of the hook contacts an edge of the biscuit. The contact between the edge of the biscuit and the angled front portion of the hook causes the hook to pivot away from the biscuit until the catch portion passes below the biscuit. The counterweight causes the hook to pivot back toward the biscuit, positioning the catch portion under the biscuit. During the upstroke, the catch portion engages the bottom side of the biscuit and causes the biscuit to break from the part as the upper trim die is raised.

Abstract: The present invention provides diamond tools, and a method for the formation thereof, using CVD techniques. In one aspect, an ephemeral mold is provided which has a diamond interface surface configured to inversely correspond to the desired shape for the working surface of a diamond layer in a tool. After the mold is provided, various CVD techniques may be used to deposit diamond layers upon the diamond interface surface of the mold. Following diamond deposition upon the diamond interface surface, the mold may be removed by various means, such as chemical etching, etc. Thus, the working surface of the diamond receives a shape which inversely corresponds to the configuration of the mold's diamond interface surface. The diamond mass may then be incorporated into a tool, if such incorporation has not yet taken place.

Abstract: The method relies on the simultaneous filling of mold (1) from its bottom through main casting gutter (3) and rising of molten metal (2) in a secondary gutter (6) which branches off from the start of casting gutter (3), with said molten metal (2) rising in secondary gutter (6) in the same amount as in mold (1), so that when the latter is full the main casting gutter (3) is sealed and feeding from the secondary gutter (6) continues, causing it to overflow and fill the corresponding feed head (5) provided on top of mold (1), with secondary gutter (6) communicating at the top with said feed head (5) so that once said feed head is full secondary gutter (6) is sealed. In this manner, the most liquid metal will reach the top part of mold (1) and may be fed to it to compensate contraction of the metal as it cools. A further object of the invention is the device (7) which seals the main casting gutter (3) and the secondary gutter (6), with these two sealing devices (7) being identical and independent.

Abstract: A heat sink includes a base having first and second regions, a first fin of a first type disposed on the first region of the base, and a second fin of a second type disposed on the second region of the base. The first and second regions of the base may be integral with or attached to one another. Such a heat sink can dissipate heat from multiple electronic components with the respective fin type that is most cost effective for each respective component. Using such a heat sink often reduces manufacturing time and costs as compared to using a separate heat sink for each component. In addition, such a heat sink can dissipate heat from multiple regions of a single electronic component with the respective fin type that is most cost effective for each region.
