Abstract: ABSTRACT OF THE DISCLOSURE           A method of viewing nuclear magnetic resonance, wherein a test sample is immersed into a unidirectional polarizing magnetic field and subjected to the effect of a radio-frequency magnetic field directed at and perpendicular to the unidirectional polarizing magnetic field.  The amplitude of the radio-frequency magnetic field is selected so as to exceed the average local magnetic field set up by the gyromagnetic nuclei of the test sample, and the component of magnetization of the test sample longitudinal to the unidirectional polarizing magnetic field is viewed at a frequency of nuclear magnetic resonance in an effective magnetic field in a frame of reference rotating about the sense of the unidirectional polarizing magnetic field at a frequency of the above radio-frequency magnetic field in the direction of natural Larmor precession of the gyromagnetic nuclei in the test sample.          The method makes it possible to appreciably increase the resolution of nuclear magnetic resonance in solids and to obtain valuable in-formation on chemical bonds, electron-nuclear interactions and other intrinsic properties of substance.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved valve pin for a valve gating injection molding system.  Heat transfer to the gate area is extremely critical in valve gating systems and this is even more so when new high density glass filled materials are being molded.  Thus it is necessary to provide substantially increased and more uniform heat transfer to the gate area.  Accordingly, the invention provides an improved valve pin having at least a portion of the valve pin adjacent the tip end being formed of an elongated hollow sealed tube which which contains a vapourizable fluid under a partial vacuum.          The back end of the tube receives heat from the surrounding heater cast to vapourize  the fluid in the area.  The vapour pressure establishes circulation of the vapour towards the cooler tip end of the tube.  The energy required to evaporate a liquid is the latent heat of vapourization and this energy is released by the vapour when it condenses upon encountering a cooler portion of the tube as it moves towards the tip end.          The condensed liquid then returns to the back end of the tube where it is again evaporated.  Circulation may be very rapid to provide a very greatly increased rate of heat transfer along the tube and the temperature drop along the length of the tube is reduced to a minimum.  This allows minimum injection pressures and valve pin forces to be used with consequent decreases in manufacturing and operating problems and expense.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to systems and methods for generating electrical power from light radiation, and specifically from solar radiation.  Among the most impor-tant existing devices for converting solar energy into electricity are devices comprising photoelectric material which is substantially monocrystalline and must be grown from crystalline solution, with a high failure rate.  De-vices and fabrication techniques utilizing polycrystalline semiconductive materials have generally proven inadequate due to high production costs.  Also, the failure rate in fabricating such devices is relatively high because of penetration by impurities.  There has been a recent attempt to form photo-voltaic power generating means with a com-pound semiconductor materials having a cadmium sulfide layer.  However, the results were poor since the oadmium sulfide was sometimes porous giving rise to shorted junc-tions.  The present invention provides an economical and reliable semiconductor photo-voltaic cell and a method for making It.  The semiconductor in the present invention is electrolytically formed at a cathode in an electrolytic solution by causing discharge or decomposition of ions or molecules of a non-metallic component with deposition of the non-metallic component on the cathode and simultane-ously providing ions of a metal component which discharge and combine with the non-metallic component at the cathode thereby forming the semiconductor compound film material thereon.  By stoichiometrically adjusting the amounts of the components, or otherwise by introducing dopants into the desired amounts, an N-type layer can be formed and thereafter a P-type layer can be formed with a junction therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE         The carebro-spinal-fluid pressure monitoring device disclosed herein employs a flexible, ribbon-like distal portion providing generally parallel front and back surfaces.  The front surface has a recess near the distal tip of the catheter so that when the tip of the catheter is inserted between the dura mater and arachnoid membrane, with the back face of the catheter supported by the patient's skull, the arachnoid membrane bridges the recess.  A longitudinal lumen communicates between the recess and a pressure monitoring device for providing a pressure trans-mitting fluid couple therebetween.  The ribbon-like distal portion is of essentially constant cross-sectional shape and is of sufficient length to permit the catheter to exit the scalp through an incision spaced from the point at which the catheter passes through the skull.  This design enables the catheter to be removed by being drawn longitudinally from the point of exit from the scalp.

Abstract: ENERGY STORAGE AND RETRIEVAL AS HEAT                     ABSTRACT         Energy is stored by heating a salt to a temperature above its latent heat of fusion to convert the salt to a liquid state. Heat is retrieved by moving a heat transfer fluid that is immiscible with the salt and has a density less than that of the salt over the top surface of the liquid salt at such a velocity that the upper layer of the salt is emulsified with the heat transfer fluid to crystalize the salt in the upper layer. Heat is thereby exothermally surrendered to the heat transfer fluid and the crystalized salt gravitates from said top surface, thereby maintaining the top surface h a liquid state. It is preferred to move the heat transfer fluid over the top surface of the salt in either a vortex pattern, or an outward radial pattern.
