Publication number: 20230003223Abstract: The water-conserving liquid ring vacuum pump system receives the output from a water ring vacuum pump, removes the air and contaminants from the water, and returns the clean water to the make-up water port on the pump, thereby saving most of the water that would normally be discarded. Friction in the pump also heats the water, so the system is designed to cool the water as well.Type: ApplicationFiled: September 13, 2022Publication date: January 5, 2023Inventor: JOHN B. DAVIDSON

Patent number: 10220495Abstract: Coupling mechanisms for engaging and releasing a tool attachment such as a socket from a drive element include an engaging element and an actuating element. The actuating element can include a collar or other manually-accessible part, and various features allow for a relatively small outside diameter for the collar or other part. These features include configuring the actuating element to contact the engaging element within the drive element, placing the biasing elements within the drive element, and forming guides for parts of the actuating element within the drive element. Also, the engaging element can move along a direction that is oriented at an oblique angle to the longitudinal axis of the drive element, in whole or in part. The engaging element can have a first part that moves obliquely in the drive element and a second part that moves radially in the drive element to engage the tool attachment.Type: GrantFiled: April 28, 2014Date of Patent: March 5, 2019Assignee: JODA ENTERPRISES, INC.Inventors: John B.

Patent number: 8258438Abstract: The condensation-free and bacteria-free pan system provides hygienic cover for a food preparation area. The system includes at least one pan having a top cover sheet, a heating element, a layer of thermal insulation and a bottom pan sheet. The top cover sheet is formed from a corrosion resistant material and is adapted for catching contaminants falling from overhead. The layer of thermal insulation is sandwiched between the top cover sheet and the heating element, and the bottom pan sheet is formed from a thermally conductive, corrosion resistant material, the bottom pan sheet having a lower wall and at least one sidewall. The top cover sheet, the layer of thermal insulation and the heating element are disposed above the bottom pan sheet to form a multilayer pan.Type: GrantFiled: September 8, 2009Date of Patent: September 4, 2012Inventor: John B.

Patent number: 7472629Abstract: A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end. The drive-stud element is coupled with a one-way drive transmitting wheel to rotate in unison therewith about an axis. The wrench can have a centering element that resists movement of the one-way drive transmitting wheel in at least one direction away from the axis. The drive-stud element and the one-way drive transmitting wheel can be separately formed. A method is also disclosed for operating a ratchet wrench with a drive-stud element with a drive stud at a first end and a drive recess at a second end.Type: GrantFiled: February 17, 2004Date of Patent: January 6, 2009Assignee: JODA Enterprises, Inc.Inventor: John B.
