Abstract: ABSTRACT OF THE DISCLOSURE         A novel latent heat accumulative material capable of accumulating heat in a temperature range best suited for the storage of solar energy was obtained by adding an organic compound or compounds such as urea [CO(NH2)2] to a system consisting of sodium acetate (CH3CO2Na) and water (H20).  Further addition of a crystal nucleus forming material or materials such as sodium pyrophos-phate decahydrate (Na4P2O7 10H2O) to said composition could minimize supercooling and allowed a wider scope of application of the present heat accumulative material.

Abstract: CERAMIC COMPOSITION ABSTRACT OF THE DISCLOSURE Improved ceramic compositions useful for cutting tools and the like are described.  They are composed of an essentially homogeneous admixture of sintered powders of an aluminum oxide base material with other refractories including zirconium oxide, titanium oxide, hafnium oxide, titanium nitride, zirconium nitride, and tungsten or molybdenum carbide. In addition to their common and improved properties of hardness and strength, many of these compositions may be made by simple cold-pressing and sintering procedures.  This avoids the known drawbacks of con-ventional hot press production.

Abstract: ABSTRACT OF THE DISCLOSURE   Wave soldering apparatus particularly adapted for soldering printed circuit boards which have closely packed chip components adhesively mounted on one side of the boards is described.  A novel nozzle assembly is dimensioned to be mounted to the solder supply conduit of a conventional wave soldering reservoir.  The nozzle assembly comprises a first nozzle which delivers a turbulent jet to the undersides of the printed circuit boards as they are conveyed over the nozzle assembly, and a second nozzle which delivers a smooth laminar wave through which the undersides of the printed circuit boards immediately subsequently pass.  The turbulent jet forces solder into the restricted spaces at which chip component contact pads are located and the smooth wave completes this soldering action by building of additional solder in a manner which discourages the formation of solder "icicles" and bridging.

Abstract: ABSTRACT OF THE DISCLOSURE           A hollow fiber diffusion device comprises a bundle of hollow fibers disposed in a generally rigid, tubular housing having relatively diametrically enlarged manifold members adjacent opposite housing ends.  A relatively resilient plastic sleeve member is carried at each end of the housing and sealed to it.  Each sleeve member carries an added inner sleeve of less inner diameter than the inner diameters of the manifold members.  The inner sleeve is coaxially positioned with the housing to receive, hold, and center the ends of the bundle.  Preferably, the sleeve is made of a material which sealingly adheres to the potting compound to facilitate the sealing of the system.

Granted: 1985-04-30
Abstract: IMPROVED STATOR VANE ASSEMBLY AND ASSOCIATED METHODS                   ABSTRACT   An annular inlet stator vane assembly positioned upstream of the bypass and core flow passages of a turbofan jet engine is provided with energy-absorbing bendable vanes which are fix-edly secured to an outer support shroud assembly and extended through slots in an inner shroud assembly.  The inner ends of the vanes are releasably secured to the inner shroud by specially designed deformable retention clips which are welded to the inner vane ends and shroud.  These features of the vane assembly cooperate to limit the circumferential extent of inlet vane damage caused by engine-ingested objects, and to help prevent damaged vane assembly structure from being drawn  through the core passage of the engine or blocking such core passage.

Abstract: ABSTRACT OF THE DISCLOSURE         An aerodynamic body provided with means for steer-ing in response to a body control variable signal has a hom-ing device supplying a measurement signal (.epsilon.m) of the error angle of the body.  For intercepting a target a computing unit, operating on the basis of relationships describing the aero-dynamic behaviour of the body in respect of the target, de-termines signal values (?,?)  representing approximations of the line of sight angular rate (?) and the attitude angular rate (?).  The input signal to the computing unit is the body control variable signal (u, um), which is dependent on the determined approximation (?) of the line of sight angular rate.  From said two signal values (?,?) a signal value (?) representing an approximation of the error angle is deter-mined.  An error angle difference signal value (.DELTA..epsilon.=.epsilon.m-?) is determined and fed back to the computing unit to update quan-tities in the relationships.

Title: Apparatus for maintaining the relative position  between wire being fed onto a bobbin and wire wound  about the bobbin for forming a coil of wire

Abstract: ABSTRACT OF THE INVENTION         An apparatus is claimed for maintaining the relative position between wire being fed onto a bobbin and wire wound about the bobbin for forming a coil comprising guide means for guiding the wire onto the bobbin, a sensing arm movably responsive to shifting of the wire upon winding thereof onto the bobbin and displacing means for synchronously displacing the guide means dependent upon the position of the wire wound about the bobbin.  The displacing means comprises, prefer-rably, a balanced rotary hydraulic servo-valve, a shaft which connects the sensing arm and the servo-valve, and a hydraulic cylinder secured to the servo valve, shiftably moveable rela-tive to the bobbin, responsive to movement of the sensing arm, such that as the angle between the wire being fed onto the bob-bin and the wire wound about the bobbin changes, the sensing arm is displaced thereby actuating said displacing means and causing movement of said guide means thereby re-establishing the rela-tive position between the wire being fed onto the bobbin and wire wound about the bobbin.       As the wire is fed onto the bobbin thereby forming a coil, the sensing arm shifts and, through the shaft, generates an error from null in the servo-valve.  The hydraulic cylinder, secured to the servo-valve housing, shifts responsive to such error from null, thereby moving the guide means, through move-ment of the servo-valve and shaft, to re-establish such null.

Abstract: ABSTRACT      A multi-speed transmission mechanism for use on a bicycle, for  example,  wherein  pressure  on  the  pedal  by  the  operator decreases or increases the diameter of the driver sprocket wheel to alter the gear ratio correspondingly.  The sprocket is provided with opposed segments which are linked to both the sprocket wheel and an inner control disc. The segments move radially outwardly or  inwardly  in  unison  responsive  to  limited  rotation  of  the control  disc  independently  of  rotation of  the  sprocket.  Such rotation is foot controlled by the operator. Pressure on the foot pedal  by the operator increases or decreases the working length of the bicycle sprocket chain by making the effective diameter of the sprocket smaller or larger. The position or gear ratio can be indexed by means of a synchronized stepped tooth index to control the required gear diameter and, therefore, the speed. This alters the gear ratio correspondingly. The gear ratio may be maintained without  change  by  a  locking  device on  the  sprocket wheel in contact with the control disc.
