Patent number: 11073150Abstract: A method, system, and apparatus for testing mobile pumps and mobile fire pumps. Exemplary embodiments described herein can reduce or eliminate the discharge of water used for testing pumps to the ground or other ambient environments. Further, exemplary embodiments can reduce or eliminate the potential for contamination of water bodies and reduce or eliminate need for large transportable reservoirs as a source of water. Exemplary embodiments can include attachment of hose valves to pump outlets for controlling a flow rate of water as well as water pressure. A hose may further be coupled to each hose valve and looped to a pump inlet, allowing for the recycling of water. Flow meters may further be provided on the looped lines to measure water flow. A low flow capacity water source and discharge may be utilized to provide further control of or adjustment to test system temperature, water flow and pressure.Type: GrantFiled: December 12, 2019Date of Patent: July 27, 2021Assignee: Haines Fire & Risk ConsultingInventor: Stephen W. Haines

Patent number: 5188589Abstract: An irrigating sleeve for use in combination with the cutting tip of a phacoemulsification handpiece containing a base having a nose and a hollow interior; a tube connected to the base at the nose having an interior surface, an open end opposite the nose and a longitudinal bore to receive the cutting tip in communication with the hollow interior of the base; and a rough texture comprised of random bumps and pits on the interior surface of the tube for reducing the amount of surface contact between the cutting tip and the interior surface of the tube during tube compression and for bathing the cutting tip continuously in a lubricant.Type: GrantFiled: October 10, 1991Date of Patent: February 23, 1993Assignee: Alcon Surgical, Inc.Inventors: Peter Wypych, Stephen W. Haines

Patent number: 5022810Abstract: A transfer device is provided for moving an object from a first location to a second location, in particular a gurney for transporting a hospital patient. The device includes a litter mechanism for carrying the object to be transported thereon and a support structure for supporting the litter mechanism and for transporting the litter mechanism between the first location and the second location. In one embodiment, the litter mechanism is pivotable with respect to the support structure to aid in transferring the object/patient thereto and therefrom. In a second embodiment, the litter mechanism is also moveable laterally and transversely with respect to the support structure. Underneath the support structure are outriggers which are extendable outwardly from the device to stabilize the device and prevent it from tipping over when the litter mechanism is extended transversely with respect to the support structure.Type: GrantFiled: September 1, 1989Date of Patent: June 11, 1991Assignee: Lavelle Aircraft Company, Inc.Inventors: Lionel Sherrow, Harold Rosenthal, Joseph M. Spitz, Stephen W. Haines

Patent number: 4983160Abstract: An improved irrigation fluid conduit for use with a coaxial surgical irrigator-aspirator for ophthalmic surgery. The conduit includes a hollow body adapted for attachment to the surgical irrigator-aspirator and a thin-walled tubular sleeve extending from the hollow body to surround the aspiration conduit of the instrument. The body and sleeve are homogeneously molded from polypropylene, which permits a rigid thin wall sleeve having a wall thickness not greater than 0.006 inches and a length-to-wall thickness ratio of more than two, and which is transparent when immersed in the aqueous humor of the eye for increased visibility by the surgeon of the adjacent tissues.Type: GrantFiled: November 28, 1988Date of Patent: January 8, 1991Assignee: Nestle S.A.Inventors: Dennis L. Steppe, Stephen W. Haines

Patent number: 4935005Abstract: A fluid flow control apparatus specially adapted for use with an ultrasonic surgical tool which provides for irrigation of a surgical site and for aspirating fluid from the site comprises a source of irrigation fluid, comprises an irrigation fluid conduit for conducting the irrigation fluid to a surgical site, an aspiration fluid conduit for conducting fluid away from the surgical site, a suction pump connected to the aspiration fluid conduit for aspirating fluid from the surgical site, a pressure-sensitive control system for removing the source of suction from the aspiration conduit when a predetermined value of suction is exceeded, and a valve for controllably admitting irrigation fluid into the aspiration fluid conduit. A check valve in the irrigation conduit prevents a reverse surge when the irrigation fluid is admitted to the aspiration conduit.Type: GrantFiled: February 1, 1989Date of Patent: June 19, 1990Assignee: Nestle, S.A.Inventor: Stephen W. Haines

Patent number: 4418944Abstract: A fluid coupling has a male member having a generally rigid base and an attached, relatively resilient face with a first fluid flow path opening from the resilient face. A female member of the coupling has a generally cylindrical receptacle with an opening for admitting the male member and a second fluid flow path for communication with the first fluid flow path in the male member when the male member is inserted into and rotated in the receptacle. The male and female members have cooperating cam surfaces opposite the opening into the fluid flow path in the member for urging the members together with a force directed at the opening. The force compresses the resilient face of the male member against the receptacle to seal the fluid flow paths about the openings. The preferred embodiment is a T coupling in which the male member has a third fluid flow path extending through it and in communication with the first fluid flow path.Type: GrantFiled: February 11, 1981Date of Patent: December 6, 1983Inventors: Stephen W. Haines, Stephen R. Marshall, Mark E. Steen, Robert C. Swanland
