Abstract
Advertising in the sky is produced by a plurality of fog emitting nozzles, for example each at the outlet of a canister containing fog producing material under pressure, which canisters are supported in spaced apart relation along a length of a winch line cable suspended from an aircraft. Each nozzle is controlled by a solenoid valve, the solenoid of which is activated on a timed schedule predetermined to contribute to the production of one or more letters, numerals, and/or designs in the sky in the creation of advertising material.
Claims7
Sky typing apparatus for attachment to an airplane, comprising:
- (a) an elongated support line arranged to be suspended from an airplane when in flight,
- (b) a plurality of fog dispensing nozzles each having an infeed end and secured in spaced apart relation along said support line,
- (c) electric solenoid valve means associated with each dispensing nozzle for opening and closing the nozzle,
- (d) container-confined fog producing material under pressure connected to the infeed end of each nozzle, and
- (e) control means connected to said valve means for selectively controlling the opening and closing of the dispensing nozzles in a predetermined sequence, the control means including a computer in the airplane capable of being programmed to provide electric output signals to control activation of the electric solenoid valve means according to airplane speed to produce a predetermined printing in the sky.
A method of sky typing utilizing only one airplane to accomplish the printing of letters, numbers, words, designs and like indicia in the sky, the sky typing method comprising:
- (a) suspending a plurality of vertically spaced fog emitting nozzles from an airplane as it travels through the sky, and
- (b) selectively emitting fog producing material from the vertically spaced nozzles in a predetermined sequence to form individual portions of indicia, the individual portions combining to form complete indicia, and
- (c) adjusting the predetermined sequence of emission of fog producing material from each individual nozzle according to variations in airplane speed, wind and other factors which affect the proper positioning of the individual indicia portions for combining with other portions to form complete indicia.
