Abstract: ABSTRACT OF THE DISCLOSURE           An electronic hydrometer for determining the density of a liquid, the hydrometer comprising a housing having a liquid receiving chamber and means to insert a liquid of which the density is to be determined in the chamber.   A float having a known weight is disposed in the chamber.  A connecting shaft is secured to the float and retained for guided displacement along its longitudi-nal axis in response to introduction of a predetermined quantity of liquid in the chamber.  A sensor is associated with a shaft for detecting a reference position of the shaft.  A permanent magnet is mounted in proximity of the shaft and has a magnetic core and a displaceable coil about the core.  The coil is secured to the shaft.  An electronic circuit means automatically adjusts the value of a current flowing in the coil to displace the coil and the shaft relative to the reference position.  The value of the adjusted current is calibrated by the circuit to generate an output signal indicative of the density of the liquid in the chamber.

Abstract: ADDITIVE FOR DECREASING VARISTOR VOLTAGE       ABSTRACT OF THE DISCLOSURE    An additive for reducing the varistor voltage of a metal oxide varistor is described. Nuclei having a grain size between about .5 and 20 microns are added to the varistor mixture in an amount between about .1 and 20% by weight. The nuclei have the metal oxide and additives present therein in substantially the same proportions as in the remainder of the varistor mixture. A method for making a low voltage varistor employing such nuclei is described. The nuclei may be obtained by pulverizing and classifying a small number of sintered varistor bodies having essentially the desired constituents but not necessarily the desired low varistor voltage.

Abstract: ABSTRACT An instrument for and method of measuring vergence limits of eyes of a subject.  The instrument has a grid with numerous equally spaced parallel lines.  Two dots on the grid are located on separate lines in the same horizontal plane when the lines are vertical.  A headrest maintains the eyes of the subject a fixed dis-tance from the grid.  Between the grid and the headrest, there is located an aperture so that the subject can view one dot with one eye and the other dot with the other eye.         In operation, the subject fuses the two dots so that they appear to be on the same line.  The grid is then rotated and the desired measurements are taken when the subject indicates.         Previous devices for measuring vergence limits use prisms or lenses between the eyes of the subject and the objects viewed by the subject.  It is sometimes difficult because of distortions to obtain consistent results with previous devices.

Abstract: ABSTRACT OF THE DISCLOSURE                 A process and apparatus provide enhanced recovery of ethylene, hydrogen and methane from the effluent produced by cracking olefins. A cracked gas is fractionally condensed in several stages. The overhead vapor from the last stage is refluxed in a rectifier tower to enable recovery of residual light hydrocarbons such as ethylene in the cracked gas and for improving the purity and yield of hydrogen.  The refrigeration for producing the reflux is obtained by expanding a portion of the over-head vapor from the rectifier tower.  Preferably, the fractional condensates of the cracked gas and the ethylene rich bottoms product from the rectifier tower are directed to a dementhanizer.  The overhead vapor from the demethanizer can be directed to the rectifier tower for recovery of ethylene contained therein.
