Publication number: 20240123202Abstract: Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.Type: ApplicationFiled: December 27, 2023Publication date: April 18, 2024Applicant: NXT Biomedical, LLCInventors: Glen Rabito, Joseph Passman, Robert C. Taft, Stanton J. Rowe, Robert S. Schwartz, Alexander Siegel

Patent number: 8947102Abstract: Soil water content and bulk electrical conductivity may be determined by time domain reflectometry at multiple depths in the soil such that the entire soil profile from the surface to a user-selected depth may be characterized. A short rise-time pulse is passed into an electrode and the reflected pulse is captured at multiple times. A waveform of reflection coefficient versus time is determined, which may be used to determine the pulse travel time, effective frequency and reflection coefficients at times necessary for the determination of the soil water content and bulk electrical conductivity.Type: GrantFiled: February 24, 2012Date of Patent: February 3, 2015Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Steven R. Evett, Scott K. Anderson, Joaquin J. Casanova, Robert C. Schwartz

Patent number: 4654933Abstract: A cotton gin lint cleaner includes a rotating saw cylinder. A continuous layer of lint cotton is fed along the cylinder by feed works. The layer is seated in and moved downstream by saw teeth on the cylinder. Foreign matter is loosened from the layer as it is moved beneath grid bars spaced along the cylinder surface. A combing bar downstream of the grid bars with teeth opposed and proximate the saw teeth further cleans the cotton layer.Type: GrantFiled: April 25, 1985Date of Patent: April 7, 1987Assignee: James L. HornInventors: James L. Horn, Robert C. Schwartz, John E. Sparks

Patent number: 4454631Abstract: An emergency actuator bar extends across an opening in the housing of a lint cleaner in a cotton gin. Actuator arms which hold the bar also normally hold a trip plate in the run position. However, a workman striking the emergency bar will remove a sear on one of the actuator arms from the trip plate to permit a spring to snap the trip plate into a stop position. When the trip plate moves to the stop position, it disconnects electrical power to a motor driving the machine. The trip plate movement also applies a brake which stops the machine.Type: GrantFiled: May 18, 1983Date of Patent: June 19, 1984Assignee: Horn and Gladden Lint Cleaner Co., Inc.Inventor: Robert C. Schwartz

Patent number: 4449248Abstract: An improved battery saving circuit for radio receivers and/or radio transceivers and/or radio communication systems of same under the control of one or more control radio transmitters and/or transceivers. The "on" and "off" time intervals for the battery saving circuits in all remote radio receivers and/or transceivers is actively and dynamically controlled in real time from a central control station so as to provide improved battery saving features.Type: GrantFiled: February 1, 1982Date of Patent: May 15, 1984Assignee: General Electric CompanyInventors: Samuel A. Leslie, Robert C. Schwartz

Patent number: 4399591Abstract: Cotton in an extractor-feeder is passed through three scrubber cylinders. The first two having grid bars of a regular 1/4 or 5/16 inch spacing and the third having grid bars at about twice the regular, or 1/2 inch spacings. Any locks of seed cotton in the trash from the third scrub cylinder are reclaimed by reclamation saw which also reclaims any cotton slung off by a main saw cylinder. Also dust is removed by a suction connected into the housing.Type: GrantFiled: March 15, 1982Date of Patent: August 23, 1983Assignee: Horn & Gladden Lint Cleaner Company, Inc.Inventors: Robert C. Schwartz, John E. Sparks

Patent number: 4214348Abstract: A trash by-pass panel is pivoted to the reclamation chute wall in a cotton gin burr and stick machine such that it may be opened to allow heavier trash to be excluded from further processing, thereby increasing the efficiency of the cotton cleaning.Type: GrantFiled: January 11, 1979Date of Patent: July 29, 1980Assignee: Horn and Gladden Lint Cleaner Co., Inc.Inventors: Robert C. Schwartz, John E. Sparks

Patent number: 4210075Abstract: The bottom of a lint feeder housing is manufactured such that the high speed belt which it houses is quickly and easily changed. The bottom of the housing is lowered after loosening the four hinged thumb bolts which secure the bottom to the housing. After the bottom is lowered, the axles which support conveyor rollers are lowered a little on one side. The worn belt is removed and a new belt is slipped between the axles and the frame of the housing then over the rollers. Once the new belt is in place, the axles are raised and the bearing housings are fixed to the feed housing. Finally, the bottom of the housing is raised and secured in place.Type: GrantFiled: November 20, 1978Date of Patent: July 1, 1980Assignee: Horn and Gladden Lint Cleaner Company, Inc.Inventors: Richard E. Jackson, Robert C. Schwartz, John E. Sparks

Patent number: 4208809Abstract: The present invention relates to a recording device to be used by choreographers as a means of forming a visual record of the precise time a cue appears on an audio track and coordinating such visually recorded cues to the audio track for use as an interface between the audio track and the microprocessor or computer devices that control the visual aspects of multi-image presentations. Additionally the present invention relates to a method of using a visual recording device as an interface. An added feature of this invention is a novel charting means that is compact in size yet stores a large quantity of information to assist the choreographer in coordinating the various events to the audio track. The charting means enables the choreographer to consider the time required between activation of the visual display equipment and the occurrence of the display to allow the equipment to cycle.Type: GrantFiled: June 7, 1978Date of Patent: June 24, 1980Assignee: Talijon, Inc.Inventor: Robert C. Schwartz

Patent number: 3981573Abstract: A highly-compact audio-visual slide projection system which makes use of an array of co-planar rear-view screen sections forming a screen matrix for presenting images selectively derived from an adjacent array of individual slide projectors. Interposed between each screen section and its correspondingly-positioned projector on the same level therewith is a V-shaped reflector assembly whose inclined front leg faces the screen section and whose reversely-inclined rear leg faces the corresponding projector.Type: GrantFiled: July 29, 1975Date of Patent: September 21, 1976Assignee: Motiva, Ltd.Inventor: Robert C. Schwartz

Patent number: 3972082Abstract: A buoyant collar is stored in a biased condition around the top outside of a boat hull. Should the boat overturn the buoyancy of the collar will work against the biasing and allow the collar, still attached to the boat, to float to the surface and provide a hand hold for the persons in the water.Type: GrantFiled: May 6, 1975Date of Patent: August 3, 1976Inventor: Robert C.
