Patent number: 4336907Abstract: A cup-shaped retainer is provided with a side wall having a mounting rim portion joined to one end thereof and a bottom wall joined to an opposite end of the side wall and having a mounting aperture sized to threadably receive a mounting screw. The side wall of the retainer is externally sized to permit insertion thereof inwardly through an access opening formed in a vehicle body or door panel or the like and the retainer is interiorly sized to removably receive a disposable cartridge filled with a corrosion inhibiting material. The mounting screw is fitted with a sealing disc or cover and may be inserted successively through the cartridge and the mounting aperture to puncture the cartridge to permit escape of its contents, to clamp the sealing disc in surface engagement with the outer surface of the vehicle body panel peripherally bounding the access opening and to effect deformation of the mounting rim portion of the retainer into clamping engagement with the vehicle body panel peripherally of the aperture.Type: GrantFiled: December 8, 1980Date of Patent: June 29, 1982Inventor: Richard D. Cummins

Patent number: 4313501Abstract: A fire extinguishing system including a vessel having an outlet normally sealed by a frangible seal. A probe is aligned with the seal and is mounted for movement in a path intersecting the seal and spring biases the probe toward the seal in the path. A restraint is provided for normally restraining the probe in the path to prevent breakage of the seal and includes a radially outwardly opening annular groove in the probe, a series of spherical elements disposed such that they partially enter the groove, and a movable cam which abuts the spherical elements oppositely of the groove and which is configured to cam the elements partially into the groove.Type: GrantFiled: May 12, 1980Date of Patent: February 2, 1982Assignee: General Fire Extinguisher CorporationInventor: Robert D. Eckert

Patent number: 4281620Abstract: A spear head access mechanism in a liquid development system wherein a machine mounted manifold, bearing a flow-through spear head connects the developer delivery system to a storage bottle. The bottle has a self sealing closure through which the spear head is forced and is encircled in an air tight manner when the bottle is pushed into operational position. A suction tube within the bottle is entered by the spear head. Upon removal of the bottle from the machine the self sealing closure forms a liquid tight seal preventing spillage of any remaining contents.Type: GrantFiled: September 28, 1979Date of Patent: August 4, 1981Assignee: Xerox CorporationInventors: John L. McChesney, Thomas A. Tackland, Ian Turner

Patent number: 4267974Abstract: A nebulizer device for producing an aerosol spray via a flow of gas at varying oxygen concentrations is disclosed. The nebulizer device comprises a body defining an initial nebulization chamber, a subsequent baffling chamber and a venturi formed therebetween. Air intake ports are disposed on the body adjacent the nebulization chamber for providing the nebulization chamber with air in predetermined quantities. Regulating means are disposed about the nebulization chamber for regulating the flow of the air through the intake ports. An aerosol system for producing an aerosol of fine particles of liquid is located in the nebulization chamber upstream of the venturi such that the flow of the aerosol spray through the venturi encourages the atmospheric fluid to enter the device through the intake ports thereby diluting the aerosol. The venturi is located downstream of the intake ports and increases the flow rate of the atmospheric fluid through the intake ports.Type: GrantFiled: July 25, 1979Date of Patent: May 19, 1981Assignee: C. R. Bard, Inc.Inventors: Charles M. Kienholz, Clifford D. Bennett

Patent number: 4256241Abstract: A fluid-solid mixing and dispensing apparatus primarily intended for use in the application of pesticide dust. The apparatus comprises a blower and a removable, disposable pesticide dust cartridge attachable to the blower in fluid-communicating relation to at least a portion of the blower's fluid flow stream. A volume control is provided so as to regulate the quantity of fluid flowing through the cartridge, thereby regulating the quantity of pesticide dust actually dispensed.Type: GrantFiled: February 1, 1979Date of Patent: March 17, 1981Inventor: Robert S. Mesic

Patent number: 4198969Abstract: A nebulizer for forming a liquid mist in a stream of gas. The nebulizing chamber carries a liquid suction conduit adapted to communicate with a supply of liquid below the nebulizing chamber. Accordingly, as suction is exerted on the nebulizing chamber, for example, by a patient breathing in, liquid is drawn upwardly into the nebulizing chamber through the suction conduit. When the liquid reaches a predetermined level it enters into the nebulizing apparatus of the device, with the result that nebulization only takes place at a predetermined minimum level of suction.Type: GrantFiled: January 4, 1979Date of Patent: April 22, 1980Assignee: Baxter Travenol Laboratories, Inc.Inventor: Robert A. Virag

Patent number: 4162501Abstract: An ink supply system for an ink printer having a pressurizable, interchangeable ink cartridge, means for pressuring the ink cartridge upon insertion into the ink cartridge receptacle, and means for establishing fluid communication between the interior of the ink cartridge and the ink supply line to the ink jet printer before pressurization of the ink cartridge occurs. The present ink supply system also includes an improved septum and needle method of establishing fluid communication.Type: GrantFiled: August 8, 1977Date of Patent: July 24, 1979Assignee: Silonics, Inc.Inventors: Charles S. Mitchell, Glenn D. Maxwell

Patent number: 4140279Abstract: A spray gun for spraying viscous liquids such as resin has a pistol-grip handle on which a lidded container is cradled with a peripheral skirt of the lid clamped against a spray nozzle head, so that a nozzle inlet tube communicates with the container. Liquid is sprayed by compressed air supplied to the nozzle through the handle under control of a valve on the handle.Type: GrantFiled: November 8, 1977Date of Patent: February 20, 1979Inventor: Robert D. Hawkins

Patent number: 4121772Abstract: A spray can for resin paints under pressure incorporates a secondary container in its interior mounted to the normally provided elongated spray tube extending into the can. The secondary container holds a catalyst and is closed off at one end by a cap with cooperating plastic sealing members further functioning to hold a weight in such a manner that the weight in the secondary container can be released by shaking of the can to generate an inertial force. Releasing of the weight shatters the secondary container thereby placing the catalyst and resin in communication with each other, the mixture passing up through the tube and out the normally provided spray outlet when the spray valve is opened.Type: GrantFiled: August 17, 1977Date of Patent: October 24, 1978Assignee: Rubin MandrellInventor: Philip J. Cronan

Patent number: 3993245Abstract: A spraying apparatus is charged with pesticide, and optionally also pressurized, by the attachment and puncture of a pressurized container of agrochemical.Type: GrantFiled: February 3, 1976Date of Patent: November 23, 1976Assignee: Shell Oil CompanyInventor: Colin P. Smith

Patent number: 3993221Abstract: A receiving chamber is provided for receiving and enclosing a container of chemical such as an insecticide. While the container is in the chamber, a punch member perforates through the top and bottom of the container to permit the insecticide therein to transfer out from the bottom of the chamber to a main tank of water for mixing therewith. The resulting mixture is then passed to suitable spray apparatus for spraying the insecticide in agricultural operations. A plunger member coaxially surrounds the punch member and extends through the top of the chamber and can be lowered to crush the container after its contents have been emptied into the main water tank. In addition, the punch member includes an internal passage for passing flushing water into the container prior to crushing of the same so that it is cleaned out. The entire system is closed so that there is no risk of operators becoming contaminated by the insecticide chemical.Type: GrantFiled: October 24, 1975Date of Patent: November 23, 1976Assignee: Western Farm Service Inc.Inventors: Edgar M. Boynton, William H. Roberts
