  • Patent number: 7584547
    Abstract: A fluid level measuring gauge for accurately measuring and reading a fluid level in a fluid level access chamber having one or more bends and interior chamfered shoulder zones, the fluid level measuring gauge including an elongate blade having an upper and lower portion where the upper and lower portions of the fluid level measuring gauge are in a constant twist formation for creating a nonwiping motion during insertion of the fluid level measuring gauge into and out of a fluid gauge access chamber, a flat shaped measuring region, including an upper port and a lower port in an up and down direction on the measuring region, a handle attached to the blade for controlled insertion and removal of the fluid level measuring gauge, and a spherical chamfer advancing guide affixed to the leading end of the elongate blade, opposite the handle.

  • Patent number: 5218699
    Abstract: A system for making procedure calls can be used with a network of computers. An application program on a local node calls a desired library procedure. The library procedure can be available on the local node or a remote node, and the location need not be known by the application. If the library procedure is available on a remote node, a remote router procedure communicates a procedure identifier to the remote node. The procedure is executed, and any results are returned to the locol node, to be returned to the application program.

  • Patent number: 5146593
    Abstract: A system software interface is provided which is called by applications programs using a standard format. All calls to system library routines are made through this interface. When called, the interface determines the location and original language of a desired library procedure. The interface then sets up parameters and calls such procedure using the calling convention which it expects. The interface receives any results generated by the library procedure, converts them to the return convention used by the calling application, and returns the results to the calling application.
