Abstract: Disclosed herein is a novel, compact, real time optical particle identification and characterization system and method of use within both gaseous and liquid media. The system can implement elastic and/or inelastic light scattering techniques simultaneously and complimentarily under the same sensor platform. By separating the sensing components from the electro-optical unit and using optical fibers for interconnection, only the sensing components need to be exposed to the environmental conditions. This reduces the design constraints on the electro-optical unit and permits the incorporation of optical components into the sensor probe that can withstand high-temperature, high-pressure, and corrosive environments. Thus, the system can be used in benign, moderate, and harsh environments.

Abstract: Disclosed herein is a novel system and method for the remote characterization of visible emissions, and more particularly, to compact, optical sensors which can remotely measure the opacity of a visible emission plume from a stationary source. Assessing visible emissions is important for compliance with environmental regulations and to support the regulatory reporting needs of Federal and State inspectors. By reducing the power consumption of the laser source and the signal processing, a compact, handheld or hand portable, battery-operable opacity measurement system can be realized while allowing eye-safe operation. The system and method may also be applied to non-stationary sources.

Abstract: Disclosed herein is a novel optical particle characterization system and method of use that can be applied to harsh environments. By separating the sensing components from the electronics unit and using optical fibers for interconnection, only the sensing components need to endure harsh environmental conditions. This reduces the design constraints on the electronics unit and permits the incorporation of optical components into the sensing probe that can withstand high-temperature and high-pressure environments.

Abstract: A fuel injector is cooled by steam during operation of a combustor. The injector includes a conduit for channeling fuel into the combustor, and a jacket covering the conduit through which steam is channeled for cooling the injector. The steam may be mixed with the fuel, or kept apart from the fuel in the injector by flowing through passageways in the jacket. Cooling can be further improved by expanding the steam through an orifice prior to entry into the injector.

Abstract: A retractable tape measure having a housing with an opening therein through which a portion of the tape extends with the remainder of the tape being coiled around a spring biased reel having a hub around which the tape is coiled. Opposed annular ends on the hub retain the tape coiled therearound. One of the annular ends has a serrated circular peripheral edge with about 100 to about 150 serrations. A first locking mechanism is shiftably mounted on the housing movable vertically into and out of engagement with the tape. Second locking mechanism is shiftably mounted on the housing movable radially into and out of engagement with the serrated edges. The second locking mechanism has a plurality of serrations thereon which when engaged with a plurality of serrations on each annular end provide a positive lock for the tape coiled around the reel hub to prevent further withdrawal of the tape. The second locking mechanism may be spring biased.

Abstract: A fixture for use with a retractable tape measure having a tab at the end thereof perpendicular to the tape. The fixture has a base with opposed side walls at least one of which defines a recess for receiving the tape end tab therein. A retaining member extends over a portion of the for frictionally retaining the tape between the base and the retaining member. A spacer bar extends away from one of the side walls intermediate the tape and the surface on which the fixture rests to protect the surface when the tape and the fixture are moved therealong. A combination of the fixture and a retractable tape measure is also disclosed.

Abstract: A clip for use with a retractable measuring tape container where the clip has a flat portion connected at one end to a first pencil holder and connected at the other end to a second pencil holder. The first pencil holder is shaped to receive and hold a pencil. The second pencil holder is shaped to receive and hold a carpenter's pencil hexagonal in transverse cross section. The clip has sinuous means intermediate said first and second pencil holders for cooperating with a releasable fastener mechanism on the container for maintaining the clip firmly against the side of the container for a retractable measuring tape.

Abstract: A hacksaw frame having a blade holder having opposed blade clamping surfaces and means for locking the surfaces in clamping relationship loosely mounted on the frame for holding a hacksaw blade, and tensioning means on the frame for holding a blade under tension.

Abstract: Means for holding prescription eyeglasses with the ear pieces removed in a conventional scuba mask in which the scuba mask comprises hood or body portion and a transparent wall surface at the front thereof. The means comprising a member which has a bottom portion and spaced side portions with the spaced side portions each terminating in a hooking end.
