Rate Jr Edward T, Heiting Robert F: Gridded X-ray tube gun. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, May 6, 1975: US3882339 (114 worldwide citation)

An X-ray generator has a Pierce type electron gun comprising an electron emissive cathode, field shaping electrodes connected thereto, a first accelerating anode spaced from the cathode and an X-ray target anode spaced from the accelerating anode for being impinged upon by a focused electron beam. C ...

Heitlinger Louis J, Bahr John P, Smith John H, Anderson Thomas W: Patient monitoring and data processing system. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, December 9, 1975: US3925762 (72 worldwide citation)

A physiological monitoring system for use with patients who are critically ill utilizes a system structure which is inherently modular, easily expandable, computer compatible, and 'fail soft'. The system is composed of bedside units, central station units and a central processing unit. Patient infor ...

Bowers David Lee: Body organ stimulator. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, September 17, 1974: US3835865 (61 worldwide citation)

The output circuit of an electric stimulator is connected to an organ such as the heart through a coupling capacitor. A semiconductor switch is triggered with a short pulse so that it partly discharges the capacitor and stimulates the organ. Immediately following the turn off of the first switch, a ...

Haye Paul G La, Bjerklie John W: Pollutant reduction with selective gas stack recirculation. Aqua Chem, Wiviott Fred, Hohenfeldt Ralph G, February 25, 1975: US3868211 (44 worldwide citation)

A flame is produced in a combustion chamber with a burner supplied with fuel and less than the amount of air for complete combustion. The remainder of the air required for complete combustion is injected separately. Stack gas containing substantial carbon dioxide is mixed selectively with the gaseou ...

Arneson Harold N: Blood pressure amplifier with zero balancing means. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, February 25, 1975: US3868679 (40 worldwide citation)

An amplifier for the signal from a blood pressure transducer is balanced to zero reference by introducing its offset signal and an offset balancing or correction signal to a summing amplifier. The resulting difference signal is fed to a comparator. A trigger signal at the start of balancing starts s ...

Arneson Harold N, Heitlinger Louis J: Physiological waveform detector. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, April 22, 1975: US3878833 (38 worldwide citation)

A physiological waveform detector such as for cardiac R-wave and blood pressure uses a comparator to compare the derivative of the waveform signal with a reference signal representing some percentage of the magnitude of the derivative of the waveform. If the derivative is of sufficient magnitude to ...

Weinfurt Phillip T, Lijewski Robert P: Vector contour plot of physiological parameters. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, May 14, 1974: US3811040 (31 worldwide citation)

Equiangularly spaced vectors correspond respectively with physiological parameters such as heart rate, blood pressure and others. The ends of the vectors are connected and preferably form a circular contour on an oscilloscope display screen or printed readout. Variation of the vectors from their ref ...

Johnson Paul J: Hinged extension for rain-pipe downspouts. Cooper III John C, Wiviott Fred, Hohenfeldt Ralph G, January 21, 1975: US3861419 (28 worldwide citation)

A hinged connection is provided for downspout extensions for directing rainwater away from the foundation of a structure. The hinged connection enables the extension to be selectively pivoted to provide clearance for routine yard work, such as mowing the lawn.

Thomas Frank A, Spatz Donald D: Method and apparatus for separating cheese whey protein. Osmonics, Cooper III John C, Wiviott Fred, Hohenfeldt Ralph G, April 29, 1975: US3880755 (26 worldwide citation)

Whey separated from milk curd during the manufacture of cheese is processed for human consumption by heating the whey to a temperature of 162.degree.F and holding it at this temperature for 16 seconds, cooling the whey to a temperature under 90.degree.F, separating protein from the whey, and chillin ...

Heiting Robert F, Rate Jr Edward T: Lens-grid system for electron tubes. General Electric Company, Hohenfeldt Ralph G, Wiviott Fred, October 28, 1975: US3916202 (22 worldwide citation)

An electron tube such as an x-ray tube has an anode target spaced from an electron beam emitting structure which include a cathode, focusing electrode and a control electrode. The control electrode surface nearest the anode is contoured to conform with selected equipotential values in the electrosta ...
