Abstract: An electrostatic spray applicator system of the type utilizing pressurized air from an external source to develop the electrical voltage driving conditions within a spray applicator. The electrical operating conditions are represented by electrical signal generating devices within the applicator, and these electrical signals are converted into optical signals within the applicator for transmission to a remote source. The optical signals are received at the remote source and converted back into electrical signals corresponding to the parameters being measured, and are subsequently converted into decimal display values for visualization by an operator.

Abstract: A low-pressure desalinization in a water chamber having an open end submerged in a water supply such as an ocean. An air exhaust pump draws air out of the water chamber to lower the surface tension of an upper stratum of water, which is thereby converted to vapor and subsequently condensed to nonsalinated water and collected in a U-shaped trap with a pair of sealing, closable valve. Although specifically designed for desalinization purposes, the apparatus may be used for distilling non-potable fresh water to potable fresh water. The system may also be used to de-water sludge in paper producing plants and also in the diary industry and other projects where large amounts of water need to be drawn off. The system would be appropriate in municipal water systems also as an odor controlling entity, in milk concentrate, maple syrup operations or cheese factories. Moreover, a velocity enhancing parabolic channel is disclosed for efficiently utilizing the potential energy of the fresh water.

Abstract: An electro-optic cell linear array, such cells being commonly referred to as PLZT cells or Kerr cells, for use in an electro-optic imager wherein the electrode lines are placed at from 15.degree. to 75.degree. relative to the centerline of the array. The advantages of such a configuration are that the electrode lines are not imaged and that adjacent cells have overlapping areas of exposure.

Abstract: A device for humidifying gases without oxygen comprised of a gas conduit for passing the gases through the device to be humidified having a portion of the conduit being permeable to water but a barrier to electrolytes. The portion of the gas conduit is positioned closely adjacent the anode of a galvanic cell also having a cathode. A reservoir is provided for placement of the galvanic cell and the portion of the gas conduit therein which is at least partially filled with an electrolyte solution.

Abstract: The present invention is a warm-up weight for softball bats that includes an open-ended cylindrical, tubular section integrally connected to a conical, tubular section. The conical section may be wedged against a tapering portion of a softball bat while the cylindrical section extends over a hitting, cylindrical, barrel portion of the softball bat. The cylindrical section includes an inner leaf spring cantilevered toward the open end of the cylindrical section.

Abstract: An improved coupler for use in assembling display frames is provided. The coupler includes a male plug, a female receptacle and a locking lever. After insertion into frame members, the plug and receptacle are engaged and locked in place. The coupler enables a frame which can be assembled and disassembled by hand and which provides a smooth, finished appearance having no outstanding protrusions.

Abstract: A diskette sleever device having a hopper for supporting a stack of empty sleeves, and a feed mechanism for receiving unsleeved diskettes, wherein the topmost empty sleeve is held in a predetermined position along the diskette transport path, and a pair of oscillatory fingers are engageable into the empty sleeve to open it, and a blower assembly is positioned adjacent the upper side of the sleeve to develop a negative pressure to create a suction force to retain the upper side of the sleeve in an open position while the transport mechanism inserts the diskette into the open sleeve.

Abstract: A wheel alignment system including four vehicle supporting members and four alignment fixtures is provided. The fixtures may be attached to the supporting members or directly to a vehicle wheel and include a guide block and a plurality of swiveling rim claws to ensure they may be quickly, securely and accurately attached, thereby increasing the speed and accuracy of wheel alignment operations.

Abstract: A double-sided central electronics complex (CEC) is provided for increasing the logic card density in a logic cage or CEC. Specifically, two logic cages or sub-enclosures are integrated, sharing one backplane card so that logic elements may be plugged into the CEC from both sides. The CEC is formed by unitary sheet metal side plates, top and bottom cast or guides and a single double-sided backplane assembly.

Abstract: A capacitance gauge system is described for determining the thickness of thin-film non-conducting material (i.e. polyethylene, vinyl, etc.). An elongated capacitance sensing head is applied to one side of the material being measured thereby disturbing the electric field produced by the head. Internal circuitry monitors the effect of the material under test and produces an output proportional to the variation in the material's thickness. A new method of resolving capacitance changes results in the ability to resolve capacitance changes on the order of 5.times.10.sup.-17 Farads in a linear manner with the benefits of simplicity, excellent stability, low power requirement, and small physical size. These factors allow said apparatus to be incorporated into a small hand-held unit. Because of this advancement in portability, accurate measurements can be made more quickly and conveniently than previously possible.

Abstract: A lightweight infant stroller is provided for carrying an infant while walking or while walking, running or jogging at a faster than walking pace. The stroller includes three large diameter wheels arranged in a tricycle configuration, a lightweight foldable frame to which the wheels are attached and an infant holder made from a flexible material supported by the frame. The frame includes pivotally connected upper portion and a lower portions, whereby the portions may be folded against one another so the stroller occupies a minimum space during transport or storage. The rear wheels are removably attached to the frame; they may be removed completely for storage and, for use, the distance between the rear wheels may be selectively varied to enhance stability.

Abstract: A double-sided backplane assembly is provided for increasing the logic element density in a logic cage or CEC.
