Abstract: This invention is an automated system and method for washing automobiles. The invention provides a device which sprays liquid onto the vehicle, while closely following the general contour of the vehicle. The system determines that contour by analyzing and recording patterns of broken light beams when the vehicle passes by an array of photoelectric sensors. The system uses the stored information about the contour of the vehicle to control the movement of a spray bar which contains a set of nozzles. As the vehicle is pulled into the washing area by a conveyor, the spray bar initially moves with the vehicle, spraying the front grill while maintaining a constant distance from the vehicle. Then, the spray bar reverses direction, while the vehicle continues to move forward. The spray bar then travels around the vehicle contour, while adjusting the direction of the nozzles so that the liquid flows in the proper direction. After having traced the entire contour, the spray bar reverses direction again.

An air cylinder is connected with the cleaning assembly for reciprocating the assembly relative to the bracket along the axis of the lance. Pressurized cleaning fluid is supplied to the lance via the rotary union. The fluid exits the lance via the plurality of radial openings, whereby the cleaning fluid is directed under pressure against the surfaces of the pendant tubes to remove slag and other built up materials therefrom.

Abstract: An automatic high pressure, frictionless, water and chemical vehicle washing device is self-contained and has a light weight aluminum frame which can be attached to a floor by adjustable leg supports or suspended from a ceiling, allowing it to be installed easily and quickly into any self-service or automatic car wash bay. The device is powered by relatively low air pressure and the spray washing head is movable in perpendicular directions allowing the spray head to seek any possible location within the boundaries of the machine itself. Photo-electric infra-red beams sense the presence of the vehicle being washed; relay signals to a programmable controller, and direct the spray head to seek the dimensions of various sized vehicles. Once the vehicle dimensions are established via communication between the photo-eye and the programmable controller, the machine maintains a safe but effective washing distance between the spray head and the vehicle surface of approximately fourteen inches.

Abstract: In a machine for etching objects, a nozzle assembly carries out an oscillating movement transverse to the conveying direction, in which the objects to be etched are guided through the machine. The device, which produces the oscillating movement, comprises a drive motor, whereof the rotary movement is converted by means of a cam disc into the oscillating movement of the nozzle assembly.

Due to this, a particularly linear displacement-time characteristic of the oscillation movement between the reversing points is achieved, which contributes to making the etching process more uniform.
