Patent number: 7413790Abstract: An adhesive attachment is provided for securely mounting an attachment component such as a threaded stud or the like on the surface of a selected substrate, wherein the adhesive attachment provides an electrically conductive ground path for grounding the attachment component and/or a selected structure mounted thereto to the substrate. In one preferred form, the attachment component is a threaded element such as a stud or nut. Upon mounting of the attachment component on the substrate and subsequent connection of the threaded element to a mating threaded member, e.g., of the selected structure to be mounted onto the attachment component, a conductive ground pin is pressed into electrical contact with the substrate for grounding the attachment component and/or the selected structure mounted thereto.Type: GrantFiled: June 8, 2005Date of Patent: August 19, 2008Assignee: Physical Systems, Inc.Inventor: Charles G.

Patent number: 7389698Abstract: A bond strength tester unit is provided for testing adhesive bond strength of a nutplate or the like attached to a substrate, such as by adhesive bonded attachment to a blind side of the substrate in substantial alignment with a substrate opening. The nutplate may be constructed according to U.S. Pat. No. 5,013,391, and carries a fastener element such as a threaded nut or the like for subsequent connection with a mating fastener element such as a threaded bolt or the like passed through the substrate opening. The tester unit includes a tool tip having a reaction head for engaging the substrate, in combination with an actuator pin for applying a test force of selected magnitude against the adhesively bonded nutplate. In the event of inadequate bond strength, the actuator pin will separate the nutplate from the substrate.Type: GrantFiled: July 17, 2006Date of Patent: June 24, 2008Assignee: Physical Systems, Inc.Inventor: Charles G.

Patent number: 7391624Abstract: An adjustable mounting bracket for secure adhesive mounting onto an exposed edge of a substrate, wherein the mounting bracket is adapted for subsequently supporting a selected structure such as tubing, wire bundles, etc., relative to the substrate. The mounting bracket includes slidably interfitting, generally L-shaped bracket members which cooperatively define a slidably overlying pair of mounting plates and an associated pair of slidably separable clamp jaw plates having inboard faces carrying a selected bonding agent and adapted to seat firmly against opposed substrate edge surfaces. A resilient fixture pin is carried by the mounting plates and can be actuated to apply a positive force urging the clamp jaw plates against the opposed surfaces of the substrate edge of the duration of a bonding agent cure time, after which the fixture pin can be forcibly removed from the mounting bracket.Type: GrantFiled: May 11, 2006Date of Patent: June 24, 2008Assignee: Physical Systems, Inc.Inventor: Charles G.

Patent number: 6928701Abstract: An improved cable tie is provided for securely bundling one or more wires or the like. The cable tie includes a buckle formed by a buckle housing having a double-ended barbed insert mounted therein. The buckle housing defines an anchor slot open at one end for seated reception of a first end of a flexible cable strap, with the barbed insert gripping and retaining the strap therein. A through channel is also formed in the buckle housing and accommodates unidirectional slide-through passage of an opposite or free end of the strap, with the barbed insert gripping and retaining the strap free end against withdrawal relative to the through channel. This flexible strap can be formed from a high strength material such as polyetheretherketone (PEEK) suitable for use in a relatively high temperature environment.Type: GrantFiled: May 6, 2004Date of Patent: August 16, 2005Assignee: Physical Systems, Inc.Inventor: Charles G.

Patent number: 6773780Abstract: A self fixturing adhesive attachment is provided for securely mounting an attachment component such as a threaded stud on the surface of a substrate. The self fixturing attachment includes a base fixture carrying the attachment component and defining a base surface for receiving a selected curable bonding agent thereon. A resilient pressure sensitive adhesive member has a first portion carried by the attachment component at a blind side thereof, a second portion secured to the base fixture, and a third portion extending therebetween. Following pressed mounting of the base fixture with bonding agent thereon onto the substrate, the attachment component is movable to press the first portion of the pressure sensitive adhesive member into adherence with the substrate, resulting in stretched elongation of the third portion thereof to pull the base fixture with a positive force toward the substrate for the duration of the bonding agent cure time.Type: GrantFiled: August 14, 2002Date of Patent: August 10, 2004Assignee: Physical Systems, Inc.Inventor: Charles G. Hutter, III

Patent number: 6727466Abstract: An adhesive attachment assembly is provided for mounting an attachment member such as a threaded stud or the like onto a substrate, wherein the attachment assembly includes a heat source for rapidly curing a selected adhesive bonding agent. The adhesive attachment assembly includes a first attachment component defining a base surface for receiving the curable bonding agent thereon, and a second attachment component adapted for temporary connection to the substrate. Upon pressed mounting of the first attachment component with bonding agent thereon onto the substrate, the second attachment component is movable into temporary engagement with the substrate, and a spring member reacts between the first and second attachment components to apply a positive force urging the first attachment component toward the substrate for the duration of the bonding agent cure time. A heat source is carried by the first attachment component for activating and/or rapidly curing the bonding agent.Type: GrantFiled: December 11, 2002Date of Patent: April 27, 2004Assignee: Physical Systems, Inc.Inventor: Charles G. Hutter, III

Patent number: 5934803Abstract: An apparatus for mixing multi-part reaction materials under a vacuum comprises a container including a mixing chamber sized to contain a reaction material. An agitator for mixing the reaction material to form a mix includes both rigid blades and flexible paddles. The rigid blades are substantially non-deflected during mixing and cut the mix, and the flexible paddles are deflected and knead the mix. The combined action of the rigid blades and the flexible paddles under vacuum throughly mixes reaction materials and removes entrapped gases from the mix. The mix can be dispensed directly from the mixing chamber. The apparatus can be used to mix viscous materials such as bone cement.Type: GrantFiled: October 30, 1997Date of Patent: August 10, 1999Assignee: Physical Systems, Inc.Inventor: Peter S. Hutter

Patent number: 5013391Abstract: An improved adhesive mounted nutplate assembly and related installation method are provided for secured mounting of a nutplate or the like onto a substrate, particularly at a blind side of the substrate in alignment with an access opening. The nutplate assembly includes a nut member having a resilient fixture pin received therein, with the nut member being adapted for adhesive mounting onto the blind side of the substrate with the fixture pin extending through the access opening. A pulling force applied to the fixture pin draws the nut member with a positive force against the substrate. The fixture pin is sized to bind within the access opening when released to maintain this positive force for the duration of an adhesive cure period, after which the fixture pin can be forcibly drawn through and removed from the nut member. A preferred nut member comprises a nutplate having a floating nut carried by a base which is adapted for adhesive mounting onto the substrate.Type: GrantFiled: June 12, 1989Date of Patent: May 7, 1991Assignee: Physical Systems, Inc.Inventors: Charles G.
