Abstract: A solar heat collector having an array of liquid transporting tubes and a plurality of heat absorber panels joined by a tube gripping accommodation on each panel providing structural integrity and good thermal conductivity.

Abstract: A vertical takeoff and landing aircraft having a tail assembly supporting structure which is pivotally connected to the fuselage, and having a shrouded fan driven by an engine submerged in the fuselage, the shrouded fan being connected to and rotatable with the tail supporting structure so as to direct the slipstream of the shrouded fan over the tail assembly at all times.

Abstract: A heat pipe to remove heat from a light fixture in a room of a building that will transfer the fixture heat to a system in a building that will in turn reject or use the fixture heat in a heating, ventilating, air conditioning system for the building.

Abstract: A wind powered electrical generating system having a suitable shaped aerodynamic duct or shroud within which a wind turbine having a fixed pitch blade is mounted, as by means of a stator means at the inlet of the duct or shroud with the stator means including mechanism for varying their effective angle of attack with regard to the approaching wind so as to provide the desired swirling approach of the wind to the turbine therebehind in achieving the desired torque and speed of shafting from the turbine to generator driven by the turbine in maintaining constant phase and frequency of the electrical output wherein the duct or shroud is mounted by a tower or shaft that will permit the cocking of the structure into the wind.

Abstract: A high-speed, real-time automatic test system element that is compatible with most contemporary computers and will interface with units under test via a front-mounted coaxial patch panel and rear exiting cables to mate with common automatic test system interconnection schemes whereby a language driver callable with programming statements enables dynamic digital testing of modern integrated circuit cards and chassis at their normal clock rates and provides a digital reading of GO/NO-GO test evaluations.

Abstract: A variable focus mirror comprising a uniform elastic disk having a mirror finish on one face thereof, which is urged against an annular fulcrum concentric with the disk by a uniform force applied at the rim of the disk. This force causes the flat disk to be flexed into a substantially spherical, nearly parabolic shape. The magnitude of the force applied controls the degree of flexure and hence the focal length of the spherical mirror. For laser beam focusing the materials are selected to be able to withstand the laser energy being reflected.

Abstract: A very low noise input charge coupled device employing switches to provide a voltage gain in all electrodes prior to or in conjunction with the transfer of the signal(s) into, for example, a shift register so as to insure a signal amplitude well above the noise level associated with the shift register of the charge coupled device.

Abstract: A supporting structure that deployed resembles a spoked wheel which is retractable into a compact volume by virtue of hinged rim and reelable spokes that is an efficient and stable structure for storing, deploying and supporting surfaces such as radar and communications antennas, shielding, earth sensing, solar cell arrays and solar energy reflectors.

Abstract: An electrical connector having a deformable tubular shell between a cable and fitting manufactured by a process of magnetically deforming the shell at one end to the underlying cable and at the other end to the underlying fitting to provide a superior EMI and shielding integrity as well as a good water tight seal without the need of potting the connection or providing special seal elements.

Abstract: A closed water/glycol solar heating system for preheating a fluid so as to reduce energy requirements in bringing said fluid up to a desired temperature and holding same, said system including a solar collector having a flexible dome.

Abstract: A process of manufacture to produce low cost pressure vessels from a length of metal tubing by use of localized heat and/or axial tensile force to shrink the diameter of the tubing at selected locations of a predetermined starting length approximately one diameter long and many diameters apart to permit subsequent separation to form open-ended pressure vessels. Subsequent conventional swaging operations could thicken and reduce the end diameters so they can be threaded.

Abstract: A device for the outside display of the level and specific density of a liquid contained within a tank, particularly for inflammable liquids, characterized by a plurality of paired light pipes having optical interface means therebetween located at intervals within a support with electrical means operable by light energy from one of the pair of light pipes being conducted thereby due to a mismatch of the index of refraction caused by an absence of fuel at the area of the optical interface to provide a display of the fluid level and/or the density of the fluid within a tank.

Abstract: An electrical connector having a deformable tubular shell between a cable and fitting manufactured by a process of magnetically deforming the shell at one end to the underlying cable and at the other end to the underlying fitting to provide a superior EMI and shielding integrity as well as a good water tight seal without the need of potting the connection or providing special seal elements.

Abstract: A jet noise suppressor nozzle comprised of a plurality of chute flow dividers through which air passes to mix with the jet gases at the boundaries formed by the downstream ends of the chute and the terminal plane of the nozzle with a plate at the forward area of the chute inlets under which jet gases are exhausted so as to create the aforementioned flow by the Coanda effect on the boundary layer air around the nozzle over the plate.
