Each of the emitters emits a laser beam along a transmit path. The LIDAR system further includes a first telecentric lens assembly positioned within the cavity and along the transmit path such that the laser beam emitted from each of the plurality of emitters passes through the first telecentric lens assembly. The LIDAR further includes a second telecentric lens assembly positioned within the cavity and along a receive path such that a plurality of reflected laser beams entering the cavity pass through the second telecentric lens assembly.

The LIDAR unit further include a plurality of emitters disposed on a circuit board within the cavity. Each of the emitters emits a laser beam along a transmit path. The LIDAR system further includes a first optic rotatable about a first axis at a first rotational speed and a second optic rotatable about a second axis at a second rotational speed that is faster than the first rotational speed. The first optic is positioned relative to the LIDAR unit such that a plurality of laser beams exiting the LIDAR unit pass through the first optic. The second optic is positioned relative to the first optic such that each of a plurality of refracted laser beams exiting the prism disk reflect off of the second optic.

Abstract: A device for aerating a liquid, such as wine, includes a cup portion with a cavity that receives an amount of liquid therein, the cavity extending between a proximal opening and a distal opening. A neck portion of the device defines an aeration section in fluid communication with the cavity. Passages in the aeration section extend laterally to an outer surface of the neck portion through which air is drawn into the aeration section. A central passage through the neck portion is in fluid communication with the aeration section and extends to a distal opening of the device. A diffuser element between the cavity and the aeration section has arms that are configured to contact the liquid as it flows from the cavity to inhibit a swirling flow of the liquid so that the liquid passes into the aeration section in a generally vertical and linear manner.

Abstract: A pressure responsive seal ring assembly includes a first and second arcuate-shaped ring segment configured for non-interlocking assembly onto a plunger body. A tab extends beyond a first end of each ring segment and is received by a recessed portion in the first end of the opposing ring segment. The tabs and recessed portions provide a gap in the outer peripheral surface of the assembled ring. A second tab extends beyond a second end of the second ring segment and is received by a recessed portion in the second end of the first ring segment. Pads provide an inter-space effective for allowing fluid flow between the interior peripheral surface and the plunger body. The ring segments expand radially outward with an increase in pressure to provide a seal and retract radially inward with a decrease in pressure. The ring segments, however, remain connected and resist fluid flow therebetween.

Abstract: An improved polished rod for use in pumping a well has the characteristics of reducing inventory and warehouse space requirements. The polished rod is in the form of an elongated high strength cylindrical metal rod of uniform external diameter and adaptable for reciprocation in an oil well stuffing box, the exterior surface being adaptable to receive a clamp thereon by which the polished rod is reciprocated, and the polished rod having male threaded end portions at opposed first and second ends, either of which may be employed for threadable attachment to a female threaded upper end of a string of sucker rods suspended in a well. The first end portion having a thread of a first size for attachment to a sucker rod string having a female thread of mating size and the second end having a thread of a different, second size for attachment to a sucker rod string having a female thread of different, mating size whereby the polished rod may be employed for use with two different sizes of sucker rod strings.

Abstract: A safety shock absorber and wiper for use in an oil well pumping unit and attached to the top of a stuffing box. The shock absorber and wiper is constructed of a high density elastomeric material which is designed to absorb the shock created in the event a polished rod breaks or slips out of the polished rod clamp and the polished rod liner head falls and impacts the top of the stuffing box. A series of circular lip seals are formed on the inside of a passage which receives the polished rod liner. The lip seals make contact with and wipe the polished rod liner. A rigid ring is encased near the bottom of the device to provide a rigid portion so that the device can be secured to the stuffing box in such a manner as to compress a seal and prevent leaks around the mating surface.

Abstract: A composite LWIR-transmitting window (10) comprising a thin sheet of LWIR-transmitting plastic film (11) reinforced by integration with an open mesh screen (12) of fine, thin or flat metal or fibrous filaments (14, 15). The preferred plastic film is polyethylene having a maximum thickness of about 0.03", most preferably less than about 0.02". The screen (12) comprises filaments such as woven wires or fibers or formed structures of thin metal, such as flat wires of honeycomb-type meshes which are thicker in the direction perpendicular to the plastic film to maximize reinforcement while minimizing blockage of LWIR through the open mesh areas (13).

Abstract: An environmentally secure polished rod liner head is provided for use on a polished rod employed in an oil well pumping system for vertically reciprocating a string of sucker rods, the polished rod extends through a stuffing box, the polished rod liner head having a body with a passageway therethrough receiving the polished rod, a polished rod liner removably secured to the lower end of the body and encompassing the polished rod, bolts extending laterally through the upper end of the body to secure the body to a polished rod so that the polished rod liner is reciprocated with the polished rod and a closure member within the body passageway above the polished rod liner biased to close in the event the polished rod should be unexpectedly removed from the body to thereby prevent hydrocarbons from being discharged through the polished rod liner and into the atmosphere.

Abstract: A process is described for the formation of high temperature superconducting materials from perovskites by inductively coupled plasma assisted oxidation. An inductively coupled plasma reactor is used to oxidize oxygen deficient perovskites in less time and at lower temperatures than previously possible. High power densities are created within the plasma reactor. This is thought to contribute to the rapid and low temperature phase change during oxidation from tetragonal to orthorhombic crystal structure apparently required for superconductivity at temperatures greater than approximately 77.degree. K. The low temperature and rapid processing time permits the application of conventional lithographic semiconductor manufacturing techniques to be applied to the potentially high temperature superconducting perovskite materials.
