Abstract
Abstract A facsimile printer-enlarger comprising an optical-mechanical scanning system by which light patterns reflected off a graphic original are scanned line by line by a photocell which converts them into electrical signals. The signals are amplified and control two air-pulse generators that are situated upstream and downstream of a fulcrum nozzle through which a stream of marking ink is directed. An air pulse from the upstream generator deflects the ink stream a small amount which deflection is greatly increased downstream due to the leverage action of the nozzle. The downstream air-pulse generator assists in the deflection. A printout is established as the ink stream strikes a recording surface. The printout is enlarged either by optically increasing the size of the reflected light patterns, mechanically enlarging the scanning ratio of the photocell and printout, or both. In a modified form the downstream air-pulse generator may be a constant airstream to act as a biasing force. In a second modified form either pulse generator may utilize a constant airstream that is modulated in accordance to the signals received. In still another form the pulse generators are staged for recording enlargements or for general fluid-amplification applications. A method of making an enlarged facsimile is also disclosed.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
88 words
A method of recording with a marking fluid comprising the steps of: forming a marking stream having a central axis; applying a fulcrum force on the marking stream with a component of said force acting perpendicular to said central axis and directing said marking stream at a recording surface; and altering the direction of said marking stream upstream of said fulcrum force in response to information signals to increase the magnitude of said perpendicular component whereby deflecting said marking stream an increased amount downstream of said fulcrum force.
Claim 2
Independent Claim
88 words
A method of recording with a marking fluid comprising the steps of: forming a marking stream having a central axis; applying a fulcrum force on the marking stream with a component of said force acting perpendicular to said central axis and directing said marking stream at a recording surface; and altering the direction of said marking stream upstream of said fulcrum force in response to information signals to increase the magnitude of said perpendicular component whereby deflecting said marking stream an increased amount downstream of said fulcrum force.
Claim 3
Dependent Claim
43 words
The method defined by claim 1, further including applying a second fulcrum force on said marking stream with a component of said force acting perpendicular to said central axis and in a direction opposite to said perpendicular component of said first fulcrum force.
Claim 4
Dependent Claim
33 words
The method defined by claim 2, wherein the resultant of said fulcrum forces on said marking stream is balanced by a constant air pulse on said marking stream downstream of said fulcrum forces.
Claim 5
Dependent Claim
108 words
The method defined by claim 2, wherein said fulcrum forces form said marking stream into a fan shape having a higher concentration of marking particles around said central axis of the stream than at its edges; intercepting at least a portion of said marking stream prior to reaching said recording surface when the marking stream is deflected; and altering the direction of said marking stream upstream of said fulcrum by an amount proportional to the magnitude of said information signals and whereby the concentration of the marking particles striking the recording surface varies depending upon the amount of deflection of the marking stream downstream of said fulcrum forces.
Claim 6
Dependent Claim
59 words
The method defined by claim 2, wherein said marking stream includes ink and further including the steps of intercepting at least a portion of said marking stream when the marking stream is undeflected and intercepting a larger portion when the marking stream is deflected and generating said information signals by converting light reflected from graphic images into electrical signals.
Claim 7
Dependent Claim
17 words
The method defined by claim 5, wherein said method produces an enlarged facsimile of said graphic image.
Claim 8
Dependent Claim
30 words
The method defined by claim 2, wherein the direction of said marking stream is altered by displacing the marking stream with a signal-controlled fluid pulse upstream of said fulcrum forces.
Claim 9
Dependent Claim
25 words
The method defined by claim 7, wherein the signal to said signal controlled air pulse is at a frequency of about 200 cycles per second.
Claim 10
Dependent Claim
30 words
