Patent number: 9921260Abstract: A system for testing electrical continuity of a device to a source wherein there is at least one conductor connecting the device to the source can include a reference capacitive load, an oscillator, and a microprocessor. The oscillator is selectively connected to the reference capacitive load and each conductor connecting the device to the source such that the frequency output of the oscillator is a function of the selected capacitive load of the oscillator. Each conductor connecting the device to the source is connected to the oscillator such that when each one is selectively connected, the output of the oscillator is a function of that conductor's parasitic self-capacitance. The microprocessor can then compare the frequency of the signal generated when each conductor is connected to the oscillator with the frequency of the signal generated when the reference capacitive load is connected.Type: GrantFiled: December 16, 2014Date of Patent: March 20, 2018Assignee: Panduit Corp.Inventors: Rachel M. Bugaris, John C. Senese, Craig T. Hoeppner, James E. Fabiszak, Richard A. Rago, Masud Bolouri-Saransar, Ronald A. Nordin, Nekheel S. Gajjar

Patent number: 9480993Abstract: A needle assembly may include a needle, a packing assembly that surrounds a first portion of the needle, and an actuatable adjustment element coupled to the packing assembly that changes a relationship between the needle and the packing assembly when actuated. The needle assembly may also include a base assembly that has a collar section and an elongated section. The elongated section includes a bore surrounding a second portion of the needle. The bore may terminate within the elongated section and before the collar section. The elongated section may be coupled to the second portion of the needle via an interference fit.Type: GrantFiled: March 7, 2014Date of Patent: November 1, 2016Assignee: Carlisle Fluid Technologies, Inc.Inventors: Mitchell M. Drozd, Paul R. Micheli, Nekheel S. Gajjar

Patent number: 9433956Abstract: The present technique provides a system and method for improving a tip assembly for a spray coating device. An exemplary spray coating device of the present technique has a twist tip with air-assist channels. The twist tip may be applied to a spray gun and provides a portion of the fluid flow passage of the gun. Rotation of the twist tip alters the fluid flow path, resulting in increased operator control.Type: GrantFiled: January 22, 2015Date of Patent: September 6, 2016Assignee: Carlisle Fluid Technologies, Inc.Inventors: Mitchell M. Drozd, Paul R. Micheli, Nekheel S. Gajjar

Patent number: 8814070Abstract: The present technique provides a system and method for improving atomization in a spray coating device. An exemplary spray coating device of the present technique has a fine finish tip with an atomization section comprising a first fluid impingement orifice, i.e., a pre-orifice, angled toward an expansion chamber and a subsequent second fluid impingement orifice. The fine finish tip is provided as a unitary assembly that may be applied to a spray gun and that provides a fixed relationship between the pre-orifice, the expansion chamber, and the second orifice, which results in refined spray characteristics, such as uniform particle distribution and uniform fan pattern shapes.Type: GrantFiled: October 20, 2010Date of Patent: August 26, 2014Assignee: Finishing Brands Holdings, Inc.Inventors: Mitchell M. Drozd, Paul R. Micheli, Nekheel S. Gajjar

Patent number: 8690083Abstract: The present technique provides a system and for improving control of a needle valve in a spray coating device. An exemplary spray coating device of the present technique has a needle valve assembly that controls entry of a fluid to a fluid delivery tip. The needle valve assembly includes an adjustment element that is at least partially located on an exterior of the spray coating device such that the adjustment element is accessible by an operator. The adjustment element may be actuated to improve a seal around the needle so that fluid does not leak from around the needle valve assembly.Type: GrantFiled: October 20, 2010Date of Patent: April 8, 2014Assignee: Finishing Brands Holdings Inc.Inventors: Mitchell M. Drozd, Paul R. Micheli, Nekheel S. Gajjar
