Abstract: An improved apparatus and method for use with a natural gas dehydrator. The apparatus and method of the invention provide for recirculation of gaseous or combustible materials so that they are not released into the atmosphere and to provide fuel for the process. Likewise, liquid hydrocarbons are collected. Various components, including separators, an absorber, wet glycol, dry glycol, an effluent condenser, heat exchangers, and a reboiler are utilized in accordance with the present invention.

Abstract: An apparatus for the internal inspection of pipes and tubes or the like, comprising an ultrasonic measuring head and a cable coupled to the measuring head, which cable can be coupled outside the pipe or tube to be measured to a device processing the measuring data, the apparatus being provided at its distal end but behind the measuring head, with a reel for winding the cable on and off.

Abstract: The present invention is a method and apparatus for the application of fluid to soil and/or plants. A cutting blade for the soil preferably goes to depths of at least 12 inches. A nozzle/spray system is provided to the cutting blade to provide fluid during cutting of the soil. The nozzle may be protected by a shield, or recessed into the blade for protection. The primary application is the eradication of dense tree and brush species, by cutting the soil and applying an herbicide below the root crown level, in a single step.

Abstract: A method and apparatus for improving antenna efficiency. A non-grounded conductive object is placed near an antenna. An insulative layer lies between the object and the antenna. The antenna used is preferably a multiband antenna, such as a discone type antenna.

Abstract: An apparatus for generating an optical illusion comprising at least one mirror, and placed in front of the mirror a figure that is visible directly as well as via the mirror, the at least one mirror being rotatable about an axis of the apparatus, and while in use, the figure describing a path about the axis of the apparatus in such a way as to be continuously in front of the mirror, the figure during its progress over the path around the axis of the apparatus undergoing a rotation from its body axis as a rate of rotation that depends on its rate of progress over the path.

Abstract: The present invention relates to a range hood for evacuating air or emitted gas, which contains oily smoke and the like generated by cooking on a range, to the outside of a house.

Abstract: A method of separating a mixture of particles in a liquid that within chosen limits have different physical property values, wherein the particles to be separated are supplied via a feeder to a screen upon which a layer of facilitating particles is disposed the size of the facilitating parties being too large to fit through the openings in the screen, wherein particles to be separated are passed through the layer of facilitating particles and through the openings in the screen and collected under the screen, the density of the particles being greater than that of the liquid, and wherein a repetitive vertical movement is provided between the particles and the liquid, respectively.

Abstract: The invention relates to a turnstile suitable for the controlled admittance of persons to a building or to an otherwise enclosed or guarded area, comprising a body mounted on a rotatable and blockable axis, which body is provided with at least three arms extending from the body, the arms being oriented such that when rotation of the body is blocked, at least one of the arms is positioned to prevent passage, while the arms extend substantially horizontally or at an angle upwards from the body.

Abstract: A method and apparatus for assembling laser diode arrays. The invention includes the use of vacuum forces and a bi-metallic clip to place a diode array and substrate in proper alignment, and to maintain that alignment while solder pre-forms are melted in an oven to accomplish a mass fusion of the assembly.
