Abstract: An apparatus for maintaining the relationship of a transverse oscillating mechanical production member containing dye valves with a product moving linearly at a relatively high speed and with the program of operation of the valves. Encoders related to both the linear motion and the transverse motion are continuously monitored and the speed of the oscillating element adjusted to match the linear motion while a proximity switch operated at one point in the oscillating member cycle monitors the synchronization of the oscillating member which is adjustable once every cycle to maintain synchronization.

Abstract: An apparatus for spray marking lumber boards with paint at predetermined locations while they are being conveyed past the device for further processing. A tachometer and a photoelectric unit are employed for determining the location and speed of the board. A solenoid-operated paint sprayer is used to deliver the paint to the boards. Electronic control circuitry is provided to activate the paint sprayer and properly coordinate the operation of paint sprayer with the location and speed of the board so the board is marked at the desired locations.
