Abstract:
A drilling template for carving into the lateral edge or the jamb of a door, a cavity shaped and dimensioned to receive either a flanged lock or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs with sharp ends, and mounting holes corresponding to those of the lock or strikeplate. The template is designed to be hammered into the door edge or jamb until the sharp edge-ended edges define the outline of the lock flange or of the strikeplate as well as the amount of wood to be removed to form the mortise necessary to nest those elements. The template can be screwed in place through mounting holes that correspond to those of the lock or strikeplate. A drill is used to rout the cavity through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes. Lateral spacers are provided to align the template against the angled part of the door jamb.
Abstract:
A cylindrical plug made of elastomeric material is introduced into a cylindrical cartridge. The rim of the cartridge is swagged-in to reduce the diameter of its opening to one-third of the cartridge internal diameter and of the closely matching plug external diameter. The cartridge is held in a chamber. A tube slidingly passing through the wall of the chamber comes in contact with the plug, and holds it within the container while the chamber is filled with a highly pressurized fluid. As the cartridge is filled with the pressurized fluid the plug is tightly held against the internal end of the tube. The tube is partially withdrawn drawing the plug against the swagged opening of the cartridge. As the tube continues to be withdrawn its internal open end is separated from the plug, and pressurized fluid begins escaping through the tube indicating that the cartridge is filled. The pressurized fluid can now be evacuated from the chamber. A central part of the plug bulging through the swagged aperture provides a positive indication that the cartridge is fulled and tightly loaded.
Abstract:
A grated thin-film surface forms a plurality of successive narrow silvered planes which are oriented to provide a composite and linear mirror. The thin film can be mounted against the inside upper section of a vehicle windshield, or sandwiched between the plies of a laminated windshield. The reflective surface is covered with a layer of liquid crystal of which the opacity can be electrically adjusted.
Abstract:
A steering mechanism where the steering wheel and command console located behind it are mounted on a generally vertical support which can be pivoted about a stationary base on the floor of the vehicle in order to accommodate two side by side driving positions. A separate linkage between the command console and the stationary base keeps the latter at a constant angular position as the steering wheel is shifted between the two driving positions. A choice of gear-and-chain combination or flexible torsion-transmitting rods are disclosed for coupling the steering wheel to the vehicle steering mechanism and for keeping the command console at a constant angular position.
