Abstract: A system for removing airborne contaminants from the effluent air streams om spray paint booths and the like. The system includes a rectangular shaped underground pool having pool of water positioned below the work area. The underground pool has a plurality of suction pipes which are uniformly distributed throughout the pool at a distance of between one and two inches above the pool of water. The suction pipes terminate in a plenum located adjacent the underground pool. A gas turbine engine which is connected to the plenum is used to draw air including airborne contaminants into the plenum from the work area. Solid airborne contaminants such as droplets of water soluble paint, sand and the like will fall into the pool of water. Lighter airborne contaminants, such as gaseous toxins are drawn through the gas turbine type engine into a after-burning incinerator.

Abstract: The device uses a sensor probe in which a plurality of electrolyte level sensor coils and/or specific gravity stratification indicators are stacked vertically in the walls of a hollow electrically insulating and chemically nonreactive elongated probe housing such that the sensor coils never come into contact with the electrolyte. Balanced transformers or series resonant coils are used to sense changes in electrolyte level and/or changes in specific gravity at various respective levels to indicate stratification of electrolyte. The fields of the sensors are changed by the amount of electrolyte in the area of the sensor coils. These changes operate to produce signals that are read as digital or analog outputs.

Abstract: A digital circuit comprising a pair of D Flip-Flops which synchronize an oming NRZ.sub.-- L serial data stream to an external ten megahertz clock signal. The combination of a third D Flip-Flop and an EXCLUSIVE-NOR gate generates a clear pulse whenever a change of state occurs within the synchronized serial data stream. This clear pulse is supplied to a ten state state machine resetting the state machine to state S0. When the state machine transition to state S4 the state machine generates an enable signal which is supplied to a toggle Flip-Flop enabling the Flip-Flop allowing the Flip-Flop to change state. The ten megahertz clock signal then clocks the toggle Flip-Flop causing the Flip-Flop to change state. At state S9 the state machine again provides an enable signal to the toggle Flip-Flop enabling the toggle Flip-Flop which allows the ten megahertz clock signal to change the state of the output of the toggle Flip-Flop.

Abstract: A multistatic radar signature measurement apparatus comprising a curvilin sensor array of photonic sensors which are used to measure the radar cross section of a target. The array of photonic sensors provide for the simultaneous collection of target scattered measurement data over an approximately semi-spherical field of view. Laser light passing through each photonic sensor of the sensor array is modulated by the photonic sensor in direct proportion to the strength/intensity of scattered waves from the target as the scattered waves pass through each photonic sensor of the sensor array. The modulated light from each sensor of the sensor array is then transmitted to an optical switching network which samples the optical signals from the array. The sampled optical signals are next provided to an RF receiver which converts the sampled optical signals to equivalent RF electrical signals.
