Abstract: A method for minimizing localized corrosion of fluid containers that occurs as a consequence of most non-chemical procedures for removing scale deposits is described. It counteracts the unavoidable side-effect of the lowering of the local pH in the vicinity of the bubbles of CO.sub.2 that are generated during an electromagnetically-induced controlled precipitation procedure. The method is a simple and facile procedure for curbing the localized corrosion occurring as a result of most non-chemical procedures for removing scales. The method is desirably performed by an induction coil wrapped around a fluid container such as a pipe encrusted with scale through which hard water is flowing. A pulsing electrical current is successively applied through the coil and halted, preferably for 3 to 10 minutes each. When the current is applied, a transitory induced magnetic field is generated in the solution, and scale encrusted on the fluid container dissolves in the solution.

Abstract: An oil-and-water mixture is supplied to a tank which is closed at the bottom and open at the top, generally midway between top and bottom. A closed vessel envelops the upper portion of the tank. A vacuum is drawn at the top of the tank and vessel. An oil coalescer is placed between the mixture supply and the open tank top and a water coalescer between the supply and the closed tank bottom. Separated oil spills over the open tank top into the vessel, and is discharged from there. Separated water is discharged from the closed tank bottom.

Abstract: A collapsible artist's water color palette comprising a plurality of rectangular trays non-fixedly attached to one another such that simple manipulation into a stacked, compact configuration for transport, or alternatively, a side-by-side, planer, configuration for mixing may be accomplished. In the stacked configuration, an upper tray serves as a lid for the tray below and, thus, prevents spillage of wet, runny paints and contamination of individual paint receptacles. A lid is provided to cover the uppermost tray when in the stacked configuration, and doubles as an additional working surface when in the planer configuration. Moreover, the subject invention provides a unitary structure so arranged with its integral components that paint receptacles and mixing surfaces may remain in an upright position during use and manipulation from one configuration to another, thus further reducing the possibility of paint spillage and contamination.

Abstract: An improved ground stake apparatus for the support of small garden fences used to protect flower beds, seedlings and the like. The invention is comprised of a stake adapted with a plurality of incrementally spaced apertures through which one or more removable U-shaped bridge members are inserted to form channels for the retention of horizontal wires of conventional fencing. Hour-glass shaped clips are also provided to secure the bridge members in place at the desired elevation along the elongate shaft of the stake. Additional features of the invention include an enlarged head having elevated nubs to reduce hammer slippage while driving the stake and a ventral fin attached along the bottom of the shaft for the prevention of both axial and lateral movement of the stake once inserted into the ground.

Abstract: A method of producing weldless resonating monolithic cavity comprising the steps of: arranging a die which can be disassembled into sectors and having the form of the internal cavity of the resonator; spinning a foil by using said die so as to provide a monolithic weldless body of metal sheet which coats exactly and completely the die; and disassembling and removing the sectors of the die through one opening of the resonator.

Abstract: A balloon inflation device with a light source involving a tube with internal electrical conducting wire such that a power source can be attached to one end of the tube, a light bulb can be attached to the other end of the tube and the power source will illuminate the light bulb. The tube also has a radially projecting flange with a chamfered edge on its outer surface such that the tube can be inserted into a balloon, light first, and the stem of the balloon can be stretched over the flange, holding the tube in place and creating a mechanical seal that prevents gas from passing between the flange and the balloon stem. The power source of the light bulb can be removed from the tube and a gas stream can be projected into the balloon, inflating it, but the tube is arranged and configured such that the gas in the balloon cannot flow out of the balloon through the tube.

Abstract: A generally vertical tube communicates at its lower end with a reservoir containing the heavier of two liquids to be separated (water in the case of oil and water separation). A vacuum system is used to create at the top of this tube a lower pressure than at the bottom. The mixture of the liquids to be separated is injected into the tube at an intermediate location between top and bottom with relatively low velocity and turbulence, and close to, but below the level of the interface between the two liquids, which becomes established as they separate. The interface level location is maintained by controlling the top-to-bottom pressure difference and the evacuation rate of the lighter liquid.

Abstract: The method and apparatus of this invention entraps liquids within wax and transforms naturally occurring or synthetic waxes into a state characterized by the fact that when the waxes solidify, they do so in forms different from those forms into which they would solidify except for the transformation. The entrapment and transformation is achieved by subjecting the waxes to force. As examples of apparatuses which can supply the force to effect the transformation, a piston apparatus and an ultrasonic apparatus are disclosed. The triglyceride waxes are one type of wax which may be transformed by the method and apparatus of this invention. Transformed triglyceride waxes are superior hosts for liquids entrapped within their matrix. The subject method is particularly effective for minimizing loss of liquids due to volatilization the entrapment process.

Abstract: A trocar consisting of a trocar in a central opening in a cannula. The cannula is provided with at least one separate passage running parallel to the central passage. The separate passage is connected to a source of cleansing fluid and a pumping means for pumping fluid through the separate passage. The separate passage terminates in an orifice near the distal end of the central opening of the cannula. In operation, when the cannula is used to provide access for a laparoscope or other viewing instrument, the end of the viewing instrument may become clouded with moisture and other debris. In this case, the end of the viewing instrument may be withdrawn into the distal end of the cannula adjacent the fluid orifices. The pumping means is actuated and cleansing fluid is forced over the end of the instrument cleaning away the obstructing matter without removing the instrument from the cannula.

Abstract: A method and apparatus for the modification of the physical properties of polymers through pressure processing techniques. The apparatus is comprised of a piston device which acts on the polymer substrate charged within the confines of a compression chamber. The piston delivers an abrupt pressure change to the substrate for the purpose of effecting the desired modification of physical properties including altered thermal, viscosity, solubility, turbidity and hardness profiles. Predictable characteristics may be imparted to the substrate through variation of pressure duration and intensity as well as the number of piston strokes applied. Modification of the physical properties of starch and gum arabic, in particular, is disclosed.

Abstract: A carrier or receptacle for a computer disc and printed matter relating to its contents is disclosed. It is comprised of a sheet of semi-rigid, durable material such as paperboard or spunbonded olefin fabricated to a specific configuration and having score lines at various locations such that flaps and hinges are formed to enable folding of the sheet into a multi-pocket storage apparatus. The pocket designated for the storage of the computer disc is dimensioned so as to permit its easy insertion and removal and to further permit the user to view the identification label of the disc when stored. One or more additional pockets for the retention of information cards or other media, containing printed matter, are also provided and have open or transparent windows to enable viewing of the printed information when inserted. The dimensions of the subject device closely conform to those of the disc stored therein such that storage of both, within conventional disc storage cabinets and the like, is made possible.
