Patent number: 7641172Abstract: An actuator installation bracket is provided for a water shutoff system including a water line, a shutoff valve having a stem, and an actuator. The actuator includes a housing having first and second ends, sides, and a pivotable actuating member. The actuator installation bracket includes a first mounting portion having first and second ends and a base portion extending therebetween. The base portion includes a number of apertures and receives the actuator. A second mounting portion extends outwardly from the base portion and is coupled to one of the water line and the shutoff valve, in order that the pivotable actuating member of the actuator is aligned with a corresponding one of the apertures of the base portion and with the stem of the shutoff valve. A key couples the pivotable actuating member to the shutoff valve stem to open and close the shutoff valve.Type: GrantFiled: September 29, 2006Date of Patent: January 5, 2010Assignee: Eaton CorporationInventors: David L.

Patent number: 7178521Abstract: A unilimb breathing circuit has a proximal end coupling member, a distal end coupling member, an expiratory tube extending between the proximal and distal end coupling members, and an inspiratory tube extending between the proximal and distal end coupling members. The expiratory tube is a corrugated expiratory tube that is expandable between a fully compressed rest position, and a fully expanded rest position, and has a plurality of intermediate rest positions. At the plurality of intermediate rest positions, the expiratory tube is capable of maintaining its rest length without the exertion of an external force.

Patent number: 7115218Abstract: A composition of matter having a metal powder or powders of specified characteristics in a Reactive Organic Medium (ROM). These compositions can be applied by any convenient printing process to produce patterns of electrical conductors on temperature-sensitive electronic substrates. The pattern can be thermally cured in seconds to form pure metal conductors at a temperature low enough to avoid damaging the substrate.Type: GrantFiled: June 28, 2001Date of Patent: October 3, 2006Assignee: Parelec, Inc.Inventors: Paul H.

Patent number: 7014885Abstract: A device and method for depositing a material of interest onto a receiving substrate includes a first laser and a second laser, a receiving substrate, and a target substrate. The target substrate comprises a laser transparent support having a back surface and a front surface. The front surface has a coating that comprises the source material, which is a material that can be transformed into the material of interest. The first laser can be positioned in relation to the target substrate so that a laser beam is directed through the back surface of the target substrate and through the laser-transparent support to strike the coating at a defined location with sufficient energy to remove and lift the source material from the surface of the support. The receiving substrate can be positioned in a spaced relation to the target substrate so that the source material is deposited at a defined location on the receiving substrate.Type: GrantFiled: July 19, 2000Date of Patent: March 21, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Alberto Piqué, Raymond Auyeung, James Fitzgerald, Douglas B.

Publication number: 20030211246Abstract: A method of printing electronic circuits and components on polymers which would normally distort at the cure temperature of the metallic printing inks is disclosed. The method consists of restraining the polymer film either mechanically or by laminating it to a rigid backing. The rigid backing can be temporary and reusable or it can be a permanent part of the product.Type: ApplicationFiled: November 12, 2002Publication date: November 13, 2003Inventors: Paul H.

Patent number: 6153348Abstract: A metal particle liquid toner using PARMOD.TM. technology can be used to electrostatically print high resolution, electrically conductive metal images. The invention comprises a dispersion of metallic toner particles having metal particles combined with a metallo-organic compound, dispersed in an electrically insulating, organic liquid such as Exxon's Isopar with the addition of a charge director to give the proper charge on the toner particles and an appropriate conductivity to the dispersion. This dispersion can be used as a liquid toner to develop an electrostatically produced latent image. The developed image can then be heated to give a conductive image on the printing plate, or it can be transferred to a desirable low or high temperature substrate by an electrostatic gap transfer method and heated to give a conductive image.Type: GrantFiled: August 6, 1999Date of Patent: November 28, 2000Assignee: Parelec LLCInventors: Paul H. Kydd, David L. Richard
