Abstract: A horizontal well completion apparatus and method for heavy, viscous oil in a producing zone (14) are disclosed using a single well. Hot injection fluid is injected into an injection string (20), reduced to a lower pressure by passing the injection fluid through a choke (22). A packer (26) separates the upper well annulus (40) from the lower well annulus (42). Insulation (21) surrounds injection tubing string (20) between the packer (26) and the well head (11). Perforations (18) in the horizontal portion (12) of the well allow heated oil to flow into the lower annulus 42 in the horizontal portion (12) of the well where is picked up by the injected fluid and lifted to the surface of the well by a jet pump (28). Temperature and pressure in the lower well annulus 42 are controlled by the temperature and pressure of the injection fluid, and the pumping rate of the produced fluids.

Abstract: A hole locator for use by installers of electrical fixtures is disclosed. The locator comprises a tapered shank of light conducting material having means at a first end to pierce a hole in a panel such as a ceiling. The tapered shank wedges in the pierced hole to hold the locator in place. A light source in the second end provides light through the length of the hole locator so the installer can easily find the locator from the opposite side of the panel. An eye or a hook in the first end provides means for pulling a wire or a pull string through the hole when the locator is withdrawn from the pierced hole.

Abstract: A headrest suitable to be mounted on a vertical surface such as a rear window for vehicles is disclosed. At least one layer of plastically deformable material and at least one layer of resilient material is used to provide energy absorptive protection for the vehicle occupant's head. Vertical position adjustment may be provided on a transparent backing plate. Various signals and insignia may be inscribed on the side of the backing plate mounted toward a window.

Abstract: There is disclosed a fuel treatment device for internal combustion engines comprising a housing having an inlet and an exit, a first metallic core in the housing, a second metallic housing in the housing and adapted to form a non-linear flow path in cooperation with the first metallic core, wherein the first metallic core comprises aluminum, and wherein the second metallic housing comprises an alloy of aluminum, copper, tin, zinc, iron, nickel, lead, sulfur and phosphorus.

Abstract: An improved drumstick is disclosed having a striking tip, a tapered portion, and a straight portion terminating in a butt end and having the center of gravity 35% to 41% from the butt end. There is also disclosed an improved tympani stick having a striking head, and a handle terminating in a butt end, the improvement comprising a weight added near the butt end sufficient to balance the tympani stick 35% to 41% from the butt end.
