US Patent:

39599051, Jun 1, 1976

Filed:

Jan 22, 1975

Appl. No.:

5/543122

Inventors:

Arthur K. Thatcher - Merritt Island FL

International Classification:

G09F 100

US Classification:

40124

Abstract:

Method and apparatus is disclosed for editing and mounting segments of recording tape containing prerecorded visual information, such as segments of an electrocardiogram (ECG) recording tape. The disclosed apparatus includes an editor for storing and feeding the tape past a window through which the tape may be viewed. Upon detection of a desired tape segment, the tape is halted and marked with the aid of a scale mounted adjacent the window opening. Thereafter, the tape is severed at each mark to form a segment having a longitudinal length corresponding to the particular type of information contained on the severed tape segment. In the preferred embodiment, the apparatus is adapted to process electrocardiogrphic recording tape and the editor scale includes a zero mark and a plurality of index marks spaced from the zero mark by distances corresponding to the desired longitudinal length of various groups of lead segments such as ECG leads I-III, V. sub. 1 -V. sub. 6, aVR, aVL and aVF. The method includes mounting the lead segments in a predetermined overlapped sequence in order to display al standard ECG lead segments within an area of 81/2 by 81/2 inches on a standardized lead segment mounting chart.

Appl. No.:

6/118451

Inventors:

Arthur K. Thatcher - Merritt Island FL
Ed R. McCarter - Maitland FL

International Classification:

F02M 2900

US Classification:

123590

Abstract:

This invention relates to a computer controlled fuel system for an internal combustion engine including a low profile carburetor for permitting engine operation on very lean fuel/air ratios without sacrificing engine performance during critical engine operations such as start up, warm-up and acceleration. The low profile carburetor provides a single point source fuel dispersion and includes one or more throttle controlled, sliding plates for increasing fuel entrainment at low engine speeds by increasing the velocity of the airstream flow through the carburetor just before the dispersion point and by maximizing the lateral distance between the point of fuel dispersion and the carburetor airstream. The computer controlled system includes various threshold circuits for providing additional fuel and/or water injection into the carburetor airstream upon detection of predetermined engine conditions.

Appl. No.:

6/723837

Inventors:

Arthur K. Thatcher - Merritt Island FL
Ed R. McCarter - late of Maitland FL

International Classification:

F02C 100
F02G 300

US Classification:

60740

Abstract:

The sonic dispersion system includes a sonic dispersion unit (18) mounted upon a mounting assembly (100,102) and having an active surface (116) with a central apex (120) positioned in spaced relationship to the mounting assembly. Material directing units (92,94) direct material against the active surface so that the material is redirected thereby toward the apex. The sonic dispersion unit (18) may be used in combination with a control system (10) which controls the amount of material provided from two separate material sources (14,34).

Inventors:

Arthur K. Thatcher - Merritt Island FL
Ed R. McCarter - Maitland FL

International Classification:

F02H 500

US Classification:

123445

Abstract:

The computer controlled sonic fuel system employs a fuel computer to convert engine manifold pressure, temperature and RPM into variable fuel pulses which are directed onto the active surface of a sonic fuel dispersion unit. This sonic dispersion unit converts pulses of fuel into a substantially nonpulsating fuel-air mixture having a fuel-air ratio which remains substantially constant regardless of variations in engine manifold pressure, temperature and RPM. This is a division of application Ser. No. 593,001 filed July 3, 1975, which is a division of appln. Ser. No. 293,377 filed Sept. 29, 1972, now U. S. Patent 4,100,896 filed July 18, 1978.
