Abstract: Systems and methods for extermination of ants may provide for the introduction of powder insecticide directly into an ant colony to deliver maximum saturation throughout the colony chambers or tunnels. Ants within the colony may track through the insecticide, and the insecticide may contaminate the ants' food source within the colony, thereby exterminating the ants with minimal disturbance to people or animals.

Abstract: A catalytic cracking system having a spray nozzle assembly adapted for more economical manufacture and efficient performance. The spray nozzle assembly includes an elongated pipe formed nozzle body formed of one or more lengths of cylindrical pipes which define a mixing zone and an elongated barrel extension zone that extends through a wall of the riser of the catalytic cracking system. The spray nozzle assembly includes an elongated liquid deflection member supported by the pipe formed nozzle body within the mixing zone which defines an impingement surface against which pressurized liquid hydrocarbon directed through a liquid hydrocarbon inlet impinges and is transversely directed from the impingement surface into the mixing zone for atomization and direction through the barrel extension zone by a stream of pressurized steam.

Abstract: A gas assisted liquid spray nozzle assembly having a nozzle body that defines a mixing zone, a liquid inlet communicating with the mixing zone from an end, and a pressurized gas inlet communicating with the mixing chamber from an upstream side. The liquid inlet includes a liquid injector extending into the nozzle body having a liquid inlet extension passage and a plurality of discharge orifices adjacent a closed downstream end which define an impingement surface for directing liquid into the mixing zone in transverse relation to a central axis of the mixing zone. The nozzle body and liquid injector define a plurality of concentrating gas discharge passages at respective locations of the injector liquid discharge orifices for causing individual pressurized gas to directly interact with transversely directed liquid into the mixing zone for enhanced atomization and ultimate discharge from a downstream spray tip.

Abstract: A gas assisted liquid spray nozzle assembly having a nozzle body that defines a mixing zone, a liquid inlet communicating with the mixing zone from a side thereof, and a pressurized gas inlet communicating with the mixing chamber from an upstream end. The liquid inlet includes a liquid inlet extension and diffuser post extending transversely into the mixing zone having a liquid extension passageway and a closed downstream end that defines an internal impingement surface disposed on a central axis of the mixing zone against which liquid impinges and is transversely directed into the mixing zone for atomization by pressurized gas directed centrally through the mixing zone from the gas inlet. The spray nozzle assembly includes a barrel extension zone downstream of said mixing zone with a spray tip for directing the atomized liquid in a predetermined spray pattern.

Abstract: A gas assisted spray nozzle assembly having a nozzle body in the form of a one piece hollow tubular member, such as a single cylindrical pipe section, which defines a mixing zone and a downstream barrel extension zone. A liquid inlet and an impingement pin are supported by said tubular member in opposed relation to each other at the mixing zone, and pressurized gas inlet is provided at an upstream end of the tubular member. The impingement pin in this case has an impingement surface radially offset from a central axis of the mixing zone on a side opposite the liquid inlet for receiving pressurized liquid and redirecting the liquid toward the central axis for enhanced intermixing with and atomization by the pressurized gas stream.

Abstract: A device for sensing the input shaft speed of an automotive automatic transmission that is driven by the engine through the fluid coupling of a torque converter. The speed sensor device includes circumferentially spaced markings about the transmission input shaft and a speed sensor that is placed at close proximity to the circumferentially spaced markings through a hole in the torque converter stator shaft. An electronic control unit (ECU) analyzes the sensor output signal and in the case of an active speed sensor it also functions as its power source. During vehicle operation, the transmission input shaft rotates the target wheel in front of the speed sensor causing modulation of its output signal. The electronic control unit analyzes the signal modulation and calculates the input shaft rotational speed. A variety of sensor/target-wheel options and sensor mounting techniques could be used depending on the application constraints.

A sensor target is mounted on an inner ring that is rotatable with respect to the outer ring, and a seal is mounted on the outer ring. A sensor is mounted on the seal in proximity to the sensor target, and a flexible electrical conductor is connected to the sensor for transmitting signals from the sensor. A portion of the flexible electrical conductor is fixed with respect to the housing. Circuitry may be electrically connected to the flexible electrical conductor. The flexible conductor and circuitry may be provided by a flexible circuit board.
