  • Publication number: 20240125385
    Abstract: A zero turning radius mower park brake system includes a park brake pawl on a transmission which engages a park brake to a pair of independently driven traction wheels. A park brake link may be pivotably mounted to the park brake pawl and connected to a left steering lever and a right steering lever. The park brake link may pivot while moving the park brake pawl forward to a park brake engaged position if only one of the steering levers is moved outward from a neutral traction drive position.

  • Publication number: 20240119753
    Abstract: A method includes transmitting a request for a computer-readable routing diagram, such as a wiring diagram, a pneumatic or hydraulic line diagram, or an optical cable diagram. The method also includes receiving, in response to the request, a routing diagram including a connectable component and at least a portion of a routing set. The connectable component is associated with both a connectable component identifier and the routing set. The routing set contains one or more routable components, such as electrical circuits, pneumatic or hydraulic lines, or optical cables. Further, the method includes displaying, on a display, the routing diagram and at least the portion of the routing set highlighted. Displaying at least the portion of the routing set highlighted occurs in response to an occurrence of the connectable component being selected from the routing diagram displayed on the display or in response to the request including the connectable component identifier.

  • Patent number: 8495844
    Abstract: A self-adjusting trim assembly used at the junction of a wall and ceiling where the wall finishes are to remain stationary while the ceiling is expected to flex due to loads on ceiling structure and normal variations in the height of the supporting structures due to temperature, moisture, creep or other factors effecting the height of the support structures. This trim assembly has two interlocking components comprised of a retainer clip having a vertical back portion (1a), a horizontal projecting tongue (1b) and the interlocking hook portion (1c) and also of a trim strip having a horizontal top portion (2a), a vertical face portion (2b) and an interlocking hook portion (2c) with the vertical face portion of the trim strip designed to cover the gap between stationary wall finishes and a flexing ceiling while trim strip remains flush with the ceiling structure, thus leaving no unsightly gap.

  • Publication number: 20100042582
    Abstract: A method for identification of application interdependency. The method includes receiving dependency data in a Application Interdependency Identification Tool (AIIT) system, and identifying a plurality of applications and dependency relationships corresponding to the dependency data by a dependency engine. The method also includes displaying the dependency data according to the identified applications and dependency relationships. There is also an AIIT system including a dependency engine and a dependency database. The AIIT system is configured to receive dependency data. The dependency engine is configured to identify a plurality of applications and dependency relationships corresponding to the dependency data and display the dependency data according to the identified applications and dependency relationships.

  • Patent number: 6634939
    Abstract: A ventilation system includes one or more exhaust fans and one or more make up air fans. Each fan has is driven by a motor operating at a constant speed. Each fan and motor are coupled by a torque converter, so that the torque applied to the fan is constant. Exhaust fan speed varies according to the ideal gas law, whereby the fan speed automatically varies in response to changes in system conditions, such as temperature and the associated changes in air density and resistance to the fan.

  • Patent number: 5096655
    Abstract: A process for producing an injection molded product includes the step of introducing an amount of a molten thermoplastic sufficient for the preparation of the injection molded product into a mold cavity. A quantity of heated gas is introduced into the mold cavity, the molten thermoplastic in the mold cavity thereby forming a gas cavity in the molten thermoplastic. The heated gas is then vented from the gas cavity and a cooling gas is introduced into the gas cavity. The injection molded product is cooled and then the cooling gas is vented from the gas cavity.
