Abstract: ABSTRACT OF THE DISCLOSURE     A liquid pipeline surge reliever system wherein a main surge relief valve of the expansible tube type is connected into a diverter line from the pipeline.  The valve opens when pressure in the diverter line exceeds a jacket control pressure.  The jacket is evacuated through a bleed valve, which may be a smaller expansible tube valve but with enough capacity to very rapid evacuation of the main valve jacket.  Gas pressure from a suit-able source is connected to the main valve jacket which, in turn, is connected to both the jacket and the inlet of the bleed valve.          Pressure of pipeline liquid in a sensing line opens a pilot valve through which the jacket of the bleed valve is exhausted should the pipeline pressure reach a predetermined surge level.  Pipeline pressure at that surge level also closes an on-off valve in the gas supply line while the surge is being relieved.

Abstract: "HITCH ASSEMBLY" ABSTRACT OF THE DISCLOSURE          A hitch assembly consists of a scissors action connectable between the clevis of a towed vehicle such as an implement or the like and between a towing vehicle such as a tractor or the like.  One end of the scissors action is closed and pivotally connected to the clevis and the other end is also closed and connectable to the tractor draw bar or the like.  A control plate is operatively con-nected between the scissors action intermediate the ends thereof and the connection to the tractor draw bar.  One end of the scissors action is connected, for example, to the front aperture in the draw bar of the towing vehicle whereupon the tractor or towing vehicle is backed up rela-tively close to the clevis of the towed vehicle.  The scissors action may then be extended and/or swung from side to side manually so that it aligns with the aperture in the clevis which may then be pinned into position.  The tractor is then backed up, and stops on the control plate engage the sides of the rearwardly extending draw bar thus forcing the alignment of the clevis with the draw bar. When the scissors action is fully retracted, a spring load-ed pin automatically engages through apertures in part of the scissors action, the draw bar and the control plate thus locking the hitch assembly in the towing position.

Abstract: Abstract of the Disclosure A variable gain servo solenoid controlled directional valve comprising a valve body having an elongated bore, a sleeve in the bore, a spool reciprocable in the sleeve and a force motor for reciprocating the spool and/or sleeve. The valve body has an inlet pressure port and outlet pres-sure ports to the interior of the sleeve.  The spool con-trols the flow through the sleeve and is movable from a null position to selective positions permitting flow to the outlets of the body.  The sleeve includes a bypass channel formed on the periphery thereof.  Upon shifting of the spool fluid flow is under the control of the spool to one of the outlets in the body.  Upon continued move-ment of the spool the sleeve is moved axially so additional fluid will flow from the inlet port in the body through the bypass channel to the selected output port of the body with-out passing through the interior of the sleeve.

The amplitude probability density functions corresponding to accurately known excitation signals may then be processed to obtain in a description of the transfer characteristic for the analog-to-digital converter to be calibrated   In a particular embodiment the excitation signals applied to the analog input of the analog-to-digital converter are pairs of signals representing accurately known rising and decaying exponential signals, and particularly exponential signals which are complementary to one another. Histograms of the digital response to the analog excitation signals are then constructed which correspond to amplitude density  functions.  The histograms may be processed in a manner which produces the transfer characteristic of the converter under test which is independent of the dynamic characteristics of the excitation signals, thus eliminating the need for accurate knowledge of the parameter values the testing circuit.

Abstract: TITLE APPARATUS FOR FAST ACCESS TO A       SERIES OF STORED IMAGES     INVENTOR Alexander Szabo ABSTRACT OF THE DISCLOSURE           The apparatus includes a frequency selective memory having a storage material for storing frequency holes in at least two spatial dimensions and a frequency dimension.  Interference patterns are stored in the memory such that each complete interference pattern is found in the spatial dimensions while the series of interference patterns is in the frequency dimension.  A laser beam is directed onto the surface of the memory to read the memory.  By changing the electric field across the storage material, subsequent interference patterns are shifted in the frequency dimension into resonance with the laser beam thereby changing the interference pattern detected.  The interference patterns may be a series of holographic interference patterns which would provide as an output a series of three dimensional images, or they may be a series of gratingd which would provide a laser beam which scans in a spatial dimen-sion as an output.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed new and improved multi-phase thermoelectric alloys (10) and a method for making the same. The alloys are disordered mate-rials having a multiplicity of matrix crystallites (12) separated by generally disordered grain boundaries (14) containing transitional phases and grain boundary regions (16) of various phases in-cluding electrically conductive phases having at least one phase having high electrical conducti-vity.    The alloys (10) are formed from a mixture of at least two separately prepared multiple element compounds preferably a first compound Bi10Sb30Te60 or Bi40Te48Se12 and a second compound Ag25Sb25Te50.  These compounds while crystalline, have different crytalline structures.  They them-selves are polycrystalline and do not represent the most stable crystalline structure.  The first compound has a rhombohedral crystalline structure and the second compound has a face centered cubic crystalline structure.  The compounds are combined in solid particulate form in proportions of 97 to 99.25 percent Bi10Sb30Te60 and 3 to .25 percent Ag25Sb25Te50 or 99 percent Bi40Te48Se12 to 1 per-cent Ag25Sb25Te50.  The mixture is then heated in a quartz tube to an elevated temperature and then drawn through a temperature gradient for cooling.    The alloys include in the grain boundary re-gions (16) various phases of silver and telluri-um.  The silver containing phases establish low resistance current paths through the crystallites to provide the alloy with high electrical conduc-tivity.  The disorder of the grain boundaries (14) and the non-highly electrical conductive phases of the grain boundary regions (16) provide low thermal conductivity desired for thermoelectric applications.    Also disclosed are alloys doped with a dopant such as tellurium iodide to form thermoelectric alloys having maximized S2o products.
