Abstract: HIGH RESISTANCE GROUND FAULT DETECTOR                    ABSTRACT OF THE DISCLOSURE       A ground fault detection system is taught which may be utilized on delta or wye connected polyphase elec-trical systems.  The presence of a ground fault causes the neutral to ground voltage of a wye connected electrical system to increase to some value other than zero.  Since a delta power system can be interconnected with a wye monitor-ing system to create an artificial neutral, a ground fault detector and pulsing arrangement can be provided between ground and the appropriate monitoring neutral.  This system includes a coil which actuates a relay system which causes a first resistor to be alternately connected into and dis-connected out of the ground current return path.  The connection is made in parallel with a fixed resistor.  This causes a change in the value of ground fault current with a given periodicity and frequency which in turn induces electromagnetic radiation around that path through which the ground fault current flows.  This in turn allows for electromagnetic determination of the place where the ground fault occurs.  In another embodiment of the invention, a broken delta secondary winding for a wye connected primary winding for a sensing transformer for a delta power system may be utilized in certain applications to modulate or pulse ground fault current.

Title: Method for altering the composition and structure  of aluminum bearing overlay alloy coatings during  deposition from metallic vapor
Inventor: BEALE HARRY A
IPC: C23C14/24
Filed: 1978-12-07
Granted: 1982-08-03
Abstract: ABSTRACT OF THE DISCLOSURE    The composition and structure of aluminum bearing overlay alloy coatings, such as MCrAlY type overlay coatings, are altered during deposition from a metallic vapor by biasing the substrate at a small negative poten-tial relative to ground while the vapor is at least partially ionized.  The coating layer deposited under such conditions is characterized by substantial freedom from leader defects and by a reduced aluminum content and resultant improved ductility.  Such coating condi-tions can be incorporated in a preselected manner into conventional deposition techniques, such as vacuum vapor deposition and sputtering, to produce a variety of coating compositional and structural variations from a single coating alloy ingot source.

Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold.  The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configu-rations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes.          The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space.  Solar energy collected on the absorber surface of the inner glass tube wall is trans-mitted to the u-tube and liquid therein.  The U-tube within the collectors is blackened and non-reflecting. Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer.  The heat transfer liquid is entirely within a closed circuit, which avoids leaks, re-duces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.    The manifold and tubes are fastened to a support structure of novel construction enabling fabrication as a module and mounting on a solar exposure of a structure such as a roof, wall or frame.  Several modules are interconnectable to desired capa-city for a particular solar powered heating or cooling system.

Abstract: ABSTRACT OF THE DISCLOSURE           A servo control apparatus for maintaining a scanning device, such as a beam of radiation, aligned with an information recording track on a moving record-ing medium, such as a record disc.  The apparatus is especially adapted for use in correcting for tracking deviations brought about by temperature-induced expan-sion and contraction of the disc, which causes the recording  track being  scanned  to move  radially out-wardly or inwardly relative to the beam of radiation. In the preferred embodiment, the apparatus includes a movable mirror  for oscillating the beam  in a radial direction, in accordance with a periodic dither signal.  This causes a corresponding variation in the intensity of the beam reflected by the disc, with the amplitude and phase angle of this intensity variation, relative to that of the dither signal, indicating the direction and magnitude of the deviation of the beam from the track centerline.  Whenever the magnitude exceeds a prescribed level, a step forward or step reverse pulse signal is coupled to a stepper motor, to increment the beam in the appropriate radial direction, whereby the beam  is maintained  substantially aligned with the centerline of the recording track.

An optical imaging system is described which is provided with an opto-electronic detection system for determining a deviation between the image plane of the imaging system and a second plane on which an image is to be formed by the imaging system. After a first reflection on the second plane an auxiliary beam which is obliquely incident on said plane is reflected along itself and mirror-inverted, is sub-sequently reflected a second time on the second plane, and is finally incident on two detectors. The dif-ference signal of the detectors, which is a measure of the said deviation, is independent of a tilted position of the second plane and of local differences in reflection in said plane.
