Abstract: A method for producing a high strength, flexible crosslinked polyethylene (PEX) material is provided wherein the base polymer is intermixed with a polymer modifier which affects the amorphous region of the polymer, leaving the crystalline portion of the base polymer virtually unaffected. Consequently, the amorphous region's density is lowered, resulting in a more flexible final product, while the crosslinked molecular structure and/or crystalline portion of the polymer, which controls the strength of the base polymer, remains strong. The polymer modifier can comprise a hydrocarbon fluid such as PAO, Group III basestocks, or a gas-to-liquid hydrocarbon. The plastic material has particular utility in the production of tubing, piping, and conduits for transporting gases, liquids, and the like, as well as wire and cable coatings such as jacketing and insulation.

Abstract: A method for minimizing spherical aberration in an optical read/write drive caused by variances in lens thickness and laser wavelength. The method provides an economic solution that pairs objective lenses with laser diodes such that the spherical aberration caused by the objective lens is offset by the spherical aberration caused by the laser wavelength, thereby minimizing or completely canceling the overall spherical aberration.

Abstract: The present invention is an apparatus for controlling a water delivery system utilizing an instant flow tankless water heater. It includes a programmable microprocessor with support circuitry to achieve control of the outlet temperature of a varying flow rate and varying inlet temperature stream. The system senses a water outlet temperature and controls AC power through an on/off mechanism to regulate power to heating elements embedded in the water stream. The capabilities of the heating elements are improved through the application of using a microprocessor to perform a proportional (P), integrating (I) and derivative (D) calculation. The calculations are used to determine the operating characteristics of the heating system and to control the heating system.

Abstract: A chart recorder is described for recording parameters such as temperature and humidity on rotating planar charts. Pens, which are used to form traces on a chart as this is rotated, are moved by pen actuators along travel paths that are parallel to a straight radius relative to the axis of chart rotation. The pen actuators are electrically moved under the control of a microprocessor to positions as determined by representative of parameter values. Various mechanical and electrical control features are described whereby pen motions are caused intermittently so as to preserve battery power and achieve long term portable operation.

The underflow of the hydrocyclone is confirned by a shroud to convert horizontal components of spray into vertical components. The effluent is driven forcibly vertically onto an endless driven filter belt.

Abstract: Apparatus is provided for moving an object in an oscillatory manner and in an arcuate path through the use of a fluid. The apparatus basically includes a hollow member or elongate tube having a curved portion and means for supplying fluid in pulses or at an increasing rate and then at a decreasing rate of flow to the tube on one side of the curved portion. The change in velocity of the fluid and the rate of change cause the movement of the tube due to inertia and, to a lesser extent, friction of the moving fluid within the tube. The density of the fluid also has a substantial effect on the movement of the tube, although gas alone will cause movement. The object to be moved is engagable by the tube and is usually supported by it. The object moved by the tube and fluid can take many forms, including signs, ornaments, figures, chimes, and clock dials.

Abstract: Electrically resistive liquids such as tap water are heated in an all solid state electrical apparatus. Spaced inner and outer conically shaped electrodes provide a flow path for the water or other liquid which is heated to a preselected temperature by selectively passing alternating current between the electrodes and through the partially conductive liquid. The resistivity of the liquid dissipates the electrical energy in the form of heat which thus increases the temperature of the flowing liquid. Rapid, safe and effective control over the electrical current flowing between the conical electrodes is achieved by an electrical control circuit including a solid state alternating current switching device, a current sensing circuit, a temperature sensing circuit and a logic circuit for selective control of the switching device.
