Patent number: 5511726Abstract: The present invention constitutes a portable nebulizer capable of producing a finely divided aerosol having uniformly sized droplets. The nebulizer includes a source of fluid such as a capillary tube coupled to a fluid reservoir to which a high voltage is applied in order to generate the aerosol by electrical atomization. The nebulizer further includes a piezoelectric crystal and a mechanism for deforming the crystal so as to generate the required voltage. The nebulizer further includes a means for mechanical positive displacement fluid control for controlling the amount of fluid atomized. By using electrical atomization to generate the aerosol and by piezoelectrically generating the voltage required for atomization, a nebulizer is provided which may be of small size so as to be suitable for hand-held operations, yet is capable of producing measured amounts of finely divided aerosols which are substantially monodispersed.Type: GrantFiled: February 23, 1993Date of Patent: April 30, 1996Assignee: Battelle Memorial InstituteInventors: Bernard J. Greenspan, Owen R. Moss, Keith E. Schleiffer, James L. Eick

Patent number: 5289948Abstract: The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber, and a corresponding piston which is acted upon by the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area, thereby generating greater hydraulic pressure for use in forming the spray.Type: GrantFiled: April 3, 1992Date of Patent: March 1, 1994Assignee: Battelle Memorial InstituteInventors: Owen R. Moss, Norman R. Gordon, Henry S. DeFord, Eugene A. Eschbach

Patent number: 5099792Abstract: An exposure system for experimental animals includes a container for a single animal which has a double wall. The animal is confined within the inner wall. Gaseous material enters a first end, flows over the entire animal, then back between the walls and out the first end. The system also includes an arrangement of valve-controlled manifolds for supplying gaseous material to, and exhausting it from, the containers.Type: GrantFiled: April 8, 1991Date of Patent: March 31, 1992Assignee: Battelle Memorial InstituteInventors: William C. Cannon, Rudolph T. Allemann, Owen R. Moss, John R. Decker, Jr.

Patent number: 4603794Abstract: A pressure multiplying dispenser for delivering fluid, preferably as a spray to the atmosphere, from a source of fluid, preferably a spray bottle, is described. The dispenser includes in combination a hollow cylindrical member, a nozzle delivery tube within the cylindrical member and a hollow actuator piston slideable within the cylindrical member which acts to multiply the pressure of a squeeze applied to the spray bottle.Type: GrantFiled: March 29, 1985Date of Patent: August 5, 1986Assignee: Battelle Development CorporationInventors: Henry S. DeFord, Owen R. Moss

Patent number: 4398498Abstract: An exposure chamber includes an imperforate casing having a fluid inlet at the top and an outlet at the bottom. A single vertical series of imperforate trays is provided. Each tray is spaced on all sides from the chamber walls. Baffles adjacent some of the trays restrict and direct the flow to give partial flow back and forth across the chambers and downward flow past the lowermost pan adjacent a central plane of the chamber.Type: GrantFiled: January 4, 1982Date of Patent: August 16, 1983Assignee: Hazleton Systems, Inc.Inventors: Owen R. Moss, James K. Briant

Patent number: 4357903Abstract: A device for producing a fluid stream of varying composition comprises a chamber having an inlet at one end and outlet at the other. Between the inlet and outlet there are substantially planar pans or baffles positioned normal to the bulk flow of fluid between the inlet and the outlet. These pans are arranged in pairs. Each pan, except those of the pair most remote from the inlet, is spaced from the walls of the chamber to permit air to flow past it. The pans of each pair are also spaced from each other, in a direction parallel to their planes, leaving an empty space along the mid-plane of the chamber. This produces a circulation and mixing of fluid between the pairs of pans or baffles. A secondary stream of fluid is introduced between two pairs of baffles in the intermediate portion of the chamber, so that the composition of the fluid is different in the portion adjacent to the outlet and the portion adjacent to the inlet.Type: GrantFiled: May 22, 1981Date of Patent: November 9, 1982Assignee: Hazleton Systems, Inc.Inventors: Owen R. Moss, Mark L. Clark, E. John Rossignol

Patent number: 4216741Abstract: A chamber for exposing animals, plants, or materials to air containing gases or aerosols is so constructed that catch pans for animal excrement, for example, serve to aid the uniform distribution of air throughout the chamber instead of constituting obstacles as has been the case in prior animal exposure chambers. The chamber comprises the usual imperforate top, bottom and side walls. Within the chamber, cages and their associated pans are arranged in two columns. The pans are spaced horizontally from the walls of the chamber in all directions. Corresponding pans of the two columns are also spaced horizontally from each other. Preferably the pans of one column are also spaced vertically from corresponding pans of the other column. Air is introduced into the top of the chamber and withdrawn from the bottom. The general flow of air is therefore vertical.Type: GrantFiled: March 5, 1979Date of Patent: August 12, 1980Assignee: Hazleton Systems, Inc.Inventor: Owen R. Moss
