Patent number: 10270320Abstract: A shaft seal assembly is disclosed having a stator including a main body and axial and radial projections therefrom. The rotor may be radially extended to encompass the axial and radial projections from said stator. A passageway formed between the radial projection of stator and rotor results in an axial passageway having its opening facing rearwardly from the rotor and away from the source of impinging coolant and/or contaminant. A concentric circumferential receptor groove in the stator facing the housing allows insertion of a conductive insert for transmission of electrostatic charge away from the shaft through the shaft seal assembly to the housing and ground. The receptor groove is opposite the axial passageway and provides for both a substantially lower contaminant environment and improved engagement with the conductive insert.Type: GrantFiled: March 21, 2017Date of Patent: April 23, 2019Assignee: Inpro/Seal LLCInventors: David C. Orlowski, Thomas D. Coe

Patent number: 5524466Abstract: A method and apparatus for hydro-forming desired features into the walls of thin-walled objects such as small tubes. A mold is provided having an internal surface that is sized and shaped to support the wall of the tubing or other workpiece and defines cavities that correspond to the desired features. A fluid filled hollow needle having no O-rings or seals thereon is provided that has at least one opening therein for supplying hydraulic fluid under pressure to the inside surface of the tubing. The needle has an outer diameter that is smaller than the inner diameter of the tubing to form a small clearance therebetween when the needle is in the tubing. The clearance is sized to prevent any substantial leakage of fluid from the needle and provide a pressure drop in the clearance sufficient to maintain the pressure of the fluid, at the portions of the wall to be deformed, high enough to deform the wall, while also facilitating insertion and removal of the needle into and from the tubing.Type: GrantFiled: July 12, 1995Date of Patent: June 11, 1996Assignee: QA Technology Company, Inc.Inventor: Thomas D.

Patent number: 4885533Abstract: A probe for providing electrical contact to electrical circuits during the testing thereof. There is a tubular housing having an open end and a generally closed end with a main portion extending from the generally closed end towards the open end and a retaining and sliding bearing portion adjacent the open end having a diameter small than the main portion. A probe plunger is disposed in the tubular housing and has a cylindrical inner portion which is a slide fit and disposed within the main portion of the tubular housing and a cylindrical outer portion of a diameter smaller than the inner portion and forming a shoulder with the inner portion at a point of meeting. The outer portion of the plunger passes through the retaining and sliding bearing portion and has an outside diameter which is a slide fit to the inside diameter of the retaining and sliding bearing portion.Type: GrantFiled: September 9, 1988Date of Patent: December 5, 1989Assignee: Q A Technology Company, Inc.Inventor: Thomas D.

Patent number: 4659987Abstract: An improvement to electrical circuit test probes of the type wherein a socket tube having a cylindrical spring loaded plunger therein is mounted in a test fixture. Electrical contact is assured between the socket and the plunger as the plunger moves longitudinally by the plunger having a resiliently flexible wand extending inwardly therefrom at an angular offset to the longitudinal axis of the plunger and the wand terminating in a bulbous contact member. The contact member is disposed within a cylindrical plunger tube and passes through an opening through which the contact member cannot pass. As a result, the wand acts as a flexible resilient finger holding the contact member firmly against the inner wall of the plunger tube as the plunger is moved in and out through its limits of movement.Type: GrantFiled: March 25, 1985Date of Patent: April 21, 1987Assignee: QA Technology CompanyInventors: Thomas D. Coe, Robert F. Gross

A plug housing having first and second cylindrical portions interconnected by a tapered portion is adapted to receive the collet member and squeeze the jaws into electrical connection with the conductor as the collet member is pushed into the plug housing. For use with the electrical circuit test probe, the plug housing has a closed cylindrical inner end adapted to be crimped into the end of a socket tube.Type: GrantFiled: March 25, 1985Date of Patent: July 1, 1986Assignee: QA Technology CompanyInventor: Thomas D.
