Abstract: ABSTRACT          An electroplating test cell comprises a tank having a housing supported within it, the housing being divided into an annular anode compart-ment and an inner cathode compartment.  A cylindrical cathode support is mounted for rotation within the cathode compartment and is vertically adjustable therein to vary its position relative to electrolyte flowed within the compartment.  The housing is supported near the bottom of the tank so that different levels of electrolyte may be maintained above the housing to provide varying liquid conditions ranging from a static pressure head to spray chamber plating.  Rotation speed of the cathode support is variable to simulate different speeds of material movement through a plating bath.

Abstract: ABSTRACT     Production is initiated, from a gas well which is kept from  pro-ducing by the hydrostatic pressure of the liquid it contains, by injecting an aqueous liquid that contains reactants which form nitrogen gas within the well or reservoir and displaces enough liquid out of the well to lower the hydro-static pressure to less than the fluid pressure in the adjacent portion of the reservoir and cause fluid to flow from the reservoir to the well.

Abstract: ABSTRACT         An elongated ski boat is provided for producing a relatively small, well-defined wake and a relatively smooth working table.  The boat comprises an elongated hull which includes a bow, a stern, a port side, a starboard side and a transom.  The hull comprises a starboard keel panel and a port keel panel, each of which extends from a location above the water line near the bow to the stern of the hull.  The keel panels join one another at a center keel line to form a V-shaped keel section having a starboard edge and a port edge.          The V-shaped keel section defines an obtuse angle at the bow which progressively increases to an angle of slightly less than 180° at the stern.  A starboard chine panel and a port chine panel are each joined to the respective edge of the keel section, extending forwardly from the stern to a location above the water line near the bow.  Each of the chine panels extends downwardly from the line of connection with the associated keel panel at an acute angle with the horizontal which angle progressively decreases to about 0° at the stern.  A starboard side panel and a port side panel connect to the associated chine panels and extend upwardly and outwardly.  The transom attaches to the starboard and port keel panels, chine panels and side panels at the stern of the hull.

Abstract: NASA Case No. LEW-12,955-1 ABSTRACT OF THE DISCLOSURE There is disclosed a method and apparatus for safely reducing abnormally high intra-ocular pressure in an eye during a predetermined time interval. This allows maintenance of normal intra-ocular pressure during glaucoma surgery.  According to the invention, a pressure regulator of the spring-biassed diaphragm type is provided with additional bias by a column of liquid. The height of the column of liquid is selected such that the pressure at a hypodermic needle connected to the output of the pressure regulator is equal to the measured pressure of the eye.  The hypodermic needle can then be safely inserted into the anterior chamber of the eye.  Liquid is then bled out of the column to reduce the bias on the diaphragm of the pressure regulator and, consequently, the output pressure of the regulator.  This lowering pres-sure of the regulator also occurs in the eye by means of a small second bleed path provided between the pressure regulator and the hypodermic needle. Alternately, a second hypodermic needle may be inserted into the eye to provide a controlled leak-off path for excessive pressure and clouded fluid from the anterior chamber.

Abstract: ABSTRACT       Apparatus for deploying a plurality of wires in predetermined co-planar relationship to each other comprises a templet having a plurality of wire-receiving grooves extending thereacross.  The grooves diverge from each other so that wires positioned in the grooves will be located in predetermined spaced-apart relationship.  The wires are pressed into the grooves by a roller which is movable across the templet.  In order to control the wires and to ensure proper placing of the wires in the grooves, a controller member is disposed in front of the roller and is movable with the roller across the templet.  The controller member elevates portions of the wires which are adjacent to the roller and approximately aligns the individual wires with the grooves into which they are to be pressed.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method and an apparatus for processing fish in the region of their gill cavities, commonly also called throating or gulletting, is described.  An unthroated fish is pushed onto a spike - shaped gulletting tool arranged above and transverse to a fish conveying path, whereby the skin ex-tending between the last gill arches and the collar bones is pierced.  The gulletting tool is provided on its upper side with a cutting edge and associated with a downwardly movable loading arm situated in its rest position approximately parallel to the spike and having a free end which is situated in the vicinity of the lower edge of the gulletting tool.          Upon completion of the piercing action, the fish moved downwardly in the conveyor path by engagement with the gill cavity side of its back bone by the loading arm, and the skin and the isthmus of the fish are severed.  The fish may then be processed furhter, e.g. fed to a filletting machine.
