Abstract: A fuel injection system is disclosed having a fuel injection nozzle which receives pressurized fuel pulses from a source. The nozzle includes a body having a tubular nozzle body with a longitudinally extending opening extending therethrough. A valve seat is located between the upstream and downstream ends of the longitudinal opening in the valve body for engagement with a valve member to thereby regulate the flow of fuel through the opening. A downstream stop member includes a hollow cylinder with a diametrical member extending across one end. The cylindrical stop member is received over the downstream end of the nozzle body with the diametrically extending member disposed across the downstream end of the longitudinal opening to thereby limit the outward range of movement of the valve member from the opening. As a result, the valve member and the downstream end of the longitudinally extending opening define an annular fuel metering orifice therebetween to regulate the flow of fuel from the nozzle.

Abstract: An artificial Christmas tree having an upright trunk supporting a plurality of branches to simulate foliage extending about the longitudinal axis of the trunk through an arc less than 360.degree. but greater than 90.degree. that permits the trunk to be supported closely adjacent a wall so that the tree occupies less floor space than a natural tree of the same height.

Abstract: A solar energy conversion system that provides for complete utilization of the solar energy impinging on solar collectors by having cylindrical lens type collection panels. This system can be used with separate heat sinks with fluid retained at different temperature levels activated to provide domestic water heating, hydronic building heating, and power generation by utilization of temperature differentials in the heat sumps and the generation of hot air pressure and flow within the panels, accomplished by special application of intermittent flow of both fluid and gas through the panel system.

Abstract: The assembly is composed of a framework having a longitudinal passage for receipt of a pipe to be wrapped and a number of crawler wheels which contact the outer wall of the pipe and which cause the framework to move longitudinally relative to the pipe. The assembly also includes brushes and wrapping assemblies mounted to rings which circumscribe the pipe. Rotation of the rings causes the brushes to scour the pipe outer wall and tape to unwind from the wrapping assembly onto the pipe. Hydraulic motors are provided on the assembly for powering the crawler wheels, brushes and wrapping assemblies. The hydraulic motors are activated by hydraulic fluid pressurized by pumps located remote from the assembly.

Abstract: An insulating material primarily for use on the interior of buildings and formed of a blanket of felted fibers (such as glass fibers) of relatively high density having an impervious flexible facing on one side for appearance and for defining a vapor barrier. The facing including a narrow edge strip extending beyond a margin of the fibers for defining a tab for overlapping and sealing a joint with an adjacent blanket. The marginal tab is protected during handling, shipping and installation by a disposable strip of insulation partially severed from the main body of the material but temporarily remaining in original position.
