Abstract
A skywriting apparatus produces visible vapor in a predetermined pattern to write messages in the sky and has a plurality of vapor generators attached to an airplane and spaced in a predetermined pattern. Each vapor generator has a burner which continuously burns, once ignited, until extinguished, and an oil injector which injects oil responsive to a remote control unit. The vapor generators are attached in a spaced relationship from a cable supported from a winch in the airplane and includes a second cable for spacing the generators as they are lowered from the plane.
Claims22
A skywriting apparatus comprising in combination:
- an airplane;
- a winch attached to said airplane;
- a support cable supported from said winch and adapted to be lifted by said winch and to be lowered by said winch;
- a plurality of vapor generating units for generating visible vapor on command;
- each said vapor generating unit being attached to said support cable in a spaced relationship to each other once the cable is extended and to be drawn together when such cable is raised;
- and
- a spacer cable operatively connecting each said vapor generator together at predetermined spaced positions along said spacer cable and support cable whereby said support cable can raise and lower said vapor generators and said spacer cable can maintain the vapor generator spaced when said support cable is lowered.
A skywriting apparatus comprising in combination:
- an airplane;
- a plurality of vapor generators attached to said airplane in a spaced relationship to each other;
- control means for controlling the release of vapor from said vapor generators, said control means having a film transport mechanism for driving film having a message thereon in a predetermined path, a lamp located adjacent said film transport on one side of a strip of film located therein;
- a plurality of fiber optic fibers having one end thereof located adjacent said film transport on the opposite side of a piece of film located therein;
- a plurality of photodetectors located adjacent the other end of said fiber optic fibers whereby signals are communicated from said film as said film is driven by the transport;
- amplifier means coupled to each said photodector to amplify signals generated by said photodetectors;
- and
- vapor generator vapor actuating means coupled to said amplifier to actuate said vapor generators to release vapor in predetermined patterns responsive to signals from said film.
A skywriting vapor generator apparatus comprising in combination:
- a burner having a solenoid-actuated fuel nozzle therein and a spark ignition for igniting saif fuel and an exhaust pipe connected to said burner;
- an oil injection having a solenoid actuated nozzle and being operatively connected to said burner exhaust pipe for discharging a vapor generating oil thereinto responsive to actuating said solenoid;
- control means being operatively connected to said burner for igniting said burner, and being operatively connected to said oil injector for actuating said oil injector responsive to said electrical signals from said control means;
- and
- said skywriting vapor generator aving stabilizer means attached thereto for stabilizing said vapor generator as it moves through the atmosphere.
