Abstract: TITLE:  METHOD OF AND MEANS FOR LIFTING WATER AND         GENERATING POWER THEREFORM INVENTOR:  GAD ASSAF           ABSTRACT OF THE DISCLOSURE         Water is raised from a lower to a higher level by creating an air/water-droplet environment which is effective to establish a pressure head that imparts an upward velocity to the air in excess of the downward drift velocity of the droplets whereby the latter are carried upwardly by the air. Such an environment is created by introducing droplets of relatively warm water into relatively cool air at the lower end of a vertically oriented lift tower thereby heating the air which rises in the lift tower with a velocity sufficient to carry the droplets to the upper end of the lift tower.  By directing the flow at the upper end of the lift tower toward the horizontal, the upwardly directed velocity component of the droplets is lost and they follow a ballistic path into a reservoir from which water is returned to the lower level through a hydraulic turbine.

Abstract: Abstract A composite, heavy-duty spool with plastic end cones, consisting of a cylindrical spool body of thick, rigid, heavy cardboard having open ends, and a pair of plastic end cones identical to each other.  When dismantled, the end cones can nest in each other so as to occupy little space.          Each end cone comprises a truncated, conical body portion all parts of which are essentially of uniform thickness.          Integral with the conical body portion of each cone is a strengthened peripheral rim of U-shaped cross section defin-ing an annular groove which faces axially away from the body portion.  At its small base part, each body portion has a transverse wall that is apertured to receive a draft bolt, and has a plurality of integral strengthening ribs each of which is disposed both on the conical exterior and on the transverse wall exterior.  The ribs lie in planes which pass through the axis of the body portion, and are shaped to effect a lead-in formation at the aperture of the transverse wall, to guide a draft bolt to the aperture.          The advantage of the present construction over the devices of the prior art are that the spool is rust-resistant, light weight and yet strudy, and the individual parts readily lend themselves to quick assembly so as to keep the manufacturing and storage costs low.

Abstract: ROTARY ELECTROPLATING CELL WITH CONTROLLED CURRENT DISTRIBUTION                    Abstract of the Disclosure An apparatus and a method for rotary electroplating a thin metallic film having a uniform thickness and composition throughout.  The apparatus includes a flow-through jet plate having nozzles of radially increasing size and uniformly spaced radially therethrough, or nozzles of the same size with varying radial spacing therebetween so as to provide a differential flow distribution of the plating solution that impinges on the wafer-cathode where the film is deposited. The spacing and size of the nozzles are critical to obtaining a uniform thickness.  The electrical currents to the wafer and to a thieving ring are controlled by variable resistors so as to keep the electrical current to the cathode constant throughout the plating process. In a preferred embodiment the flow-through jet plate has an anode associated therewith in which the exposed area of the anode is maintained at a constant amount during the deposition.  This method can simultaneously deposit with a uniform thickness and composition elements having a minimum gap or part size of 1 micrometer or less.

Abstract: AUTOMATIC EJECT APPARATUS FOR A SELF-CONTAINED                  RECORD PLAYER            ABSTRACT OF THE DISCLOSURE         Automatic eject apparatus is provided for a self-contained record player, that is, a record player of the type having a housing, a carrier movable into and out of the housing, a turntable mounted on the carrier and a tone arm pivotably supported on the carrier and movable between raised and lowered positions.  An energizable carrier drive bi-directionally drives the carrier into and out of the housing between withdrawn and retracted positions, respec-tively.  Sensors sense when the carrier is in its withdrawn and retracted positions, and a tone arm position detector detects when the tone arm is in its raised and lowered positions, respectively.  A tone arm drive is energizable to pivotally drive the tone arm to and from a reset position.    When an eject switch is operated, drive control circuitry responds thereto to energize the carrier drive in accordance with the position sensed by the sensors whereby the carrier is driven into the housing when the sensors sense that the carrier is in its withdrawn position, and the carrier is driven out of its housing when the sensors sense that the carrier is in its retracted position and that the tone arm position detector detects that the tone arm is in its raised position.  The drive control circuit concurrently energizes the tone arm drive to pivot the tone arm to its reset position.          The carrier thus may be ejected from the housing at any time, even when a playback operation is being performed.                             -i-
