Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servomotors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.

Abstract: A fan spray nozzle provides a linear spray pattern of very fine droplets suitable for spraying thin invert emulsions containing active agents such as herbicides, pesticides, fungicides, growth regulators and the like, especially using an array of nozzles mounted on a moving vehicle. Each nozzle has a nozzle plug fitted into a nozzle body having an indentation complementary to the plug. A chamber in the body is coupled to the indentation and to an inlet for feeding pressurized liquid into the chamber. One or both of the nozzle plug and the nozzle body have a plurality of narrow grooves (0.001 to 0.015 inch or 25 to 400 microns in width), in a line along an abutment between the nozzle body and the nozzle plug and leading from the chamber to an external wall of the body. A manual release such as a thumbscrew holds the nozzle plug in the indentation, and when released enables the nozzle plug to pivot or hinge relative to the nozzle body, thereby separating the two and flushing the orifices in a direction limited to the direction of normal spray discharge. The hinging is facilitated by an elongated seal between the plug and the body along an edge of the indentation opposite from the orifices, and an O-ring on the shaft of the release that resiliently biases the plug to lift from the body.
