Patent number: 4941806Abstract: A bottled water supply system comprises a base unit into which a standard five gallon water bottle may be installed. The cover of the base unit supports the bottle in an inverted position such that the neck of the bottle projects into a water reservoir within the unit. A pump, also housed within the unit, draws water from the reservoir and pumps it to the water supply line of an appliance. Power for the pump is controlled by a pressure actuated switch so that the pressure in the supply line is maintained a predetermined level. A pair of magnetic reed switches are housed within a water tight tube in the reservoir below the normal water level. A magnetic float surrounding the tube actuates one of the reed switches when the water level falls below the neck of the water bottle, thereby actuating an alarm indicating that the bottle is empty. The second switch is actuated just before the water level drops to the level of the pump supply tube and interrupts power to the water pump.Type: GrantFiled: December 12, 1988Date of Patent: July 17, 1990Assignee: The McGregor CompanyInventors: Toran S.

Additives contained in the bottle are prevented from entering the system before the seal is ruptured, thus enabling predisposition of the bottle in the system for later dispersement of additive without premature leakage of the additives into the system.Type: GrantFiled: May 1, 1989Date of Patent: February 20, 1990Inventor: Michael B. Mivelaz

Device for dispensing a concentrate into a liquid without exposing the concentrate to the atmosphere
Patent number: 4793476Abstract: A device which can dispense a composition such as a pesticide, herbicide, fungicide, or other toxic composition into a liquid such as a solvent without exposing the composition to the atmosphere. The device comprises a jacket having a perforated top and an open bottom; a container having an open top which is sized to be removably retained within the jacket; a means for breaking a seal over the top of the container only after the container has been sealingly engaged within the jacket; a means for sealingly engaging the container and the jacket after the container has been inserted a predetermined distance into the jacket; and a graspable element coupled to the base of the container for allowing the container to be manipulated when the container is retained within the jacket.Type: GrantFiled: March 30, 1988Date of Patent: December 27, 1988Assignee: Earl H. SchruppInventor: Earl H. Schrupp -
Patent number: 4767058Abstract: A spray head is disclosed having an aligned fluid conduit leading respectively to a source of pressurized water and a spray outlet. A rotatable, vertically movable valve element lies in a suitable bore in the spray head between the conduits. The valve has a horizontal conduit therethrough which merges with a vertical conduit adapted to convey liquid from a container to which the spray head is connected. A frangible locking collar lies between the head of the valve and the upper surface of the spray head holding the valve from either rotational or vertical movement towards the container. Breaking and removal of the locking collar allows for 90.degree. rotation of the valve to unseat inwardly from a flange carried by the valve body from inwardly projecting retaining flanges carried by the spray head body thereby allowing for downward movement of the valve to puncture a seal over the container holding the liquid.Type: GrantFiled: June 30, 1986Date of Patent: August 30, 1988Assignee: Chesebrough-Pond's Inc.Inventors: Joseph P. LaRosa, Michael H. Lombardi

Patent number: 4666062Abstract: A device for mixing and spraying a mixture composed of at least two components, such as liquids, and of a propellant, comprising two containers disposed within each other for receiving the components to be mixed and the propellant, and comprising a dispensing valve mounted on the outer container and including a movably mounted dispensing tube. The dispensing valve is adapted to act on a closure member of the inner container in such a way that the inner container may be broken open by normal actuation of the dispensing valve or the dispensing tube thereof. In order to achieve and maintain a defined fluid communication between the interior of the inner container and the interior of the outer container, the closure member of the inner container preferably includes a sealing cap adapted to be pushed or urged into the container opening by the dispensing tube of the dispensing valve.Type: GrantFiled: January 8, 1985Date of Patent: May 19, 1987Assignee: F.P.D.

Patent number: 4646848Abstract: The invention is a fire suppression system for an aircraft 10 of the type having a main cabin compartment 12, such as a passenger compartment and a plurality of closable or closed-off subcompartments. These subcompartments can be any area which is separated by fixed structure from the main cabin and therefore are normally not accessible. The fire suppression system comprises a plurality of ducts 57 coupling a plurality of subcompartments 14, 15, 22 to the main compartment. The plurality of ducts 57 have first ends of the ducts 57 terminate in nozzles 58 within the subcompartments adapted to distribute the fire suppression chemical in a specific pattern and second ends terminating in disconnect valve halves 59 accessible from the main cabin compartment. A portable unit 30 having a tank 42 filled with a fire suppression chemical under pressure is moveable within the main compartment 12. Preferably, the fire suppression chemical is Halon stored under nitrogen gas pressure.Type: GrantFiled: October 26, 1984Date of Patent: March 3, 1987Assignee: Lockheed CorporationInventor: Wilhelm A. Bruensicke

Patent number: 4385714Abstract: The invention relates to an apparatus for and a method of spreading gaseous, liquid and powdered materials, that are applicable to pressing out creamy or foamy materials, too. According to the method a material to be spread is placed in a tank into the pressure vessel, overpressure is developed in the pressure vessel for spreading, whereby the tank moves towards the spreading nozzle and the spreading nozzle is communicated with the interior of the tank. The apparatus comprises a pressure vessel with its interior space divided into two sections, one of them contains the fuel tank ensuring the overpressure, the other one contains the material tank sealing airtightly the first section. The invention provides reliable spreading, not polluting the environment, the pressure vessel of the apparatus is not to be thrown away, and the tanks inside the vessel are replaceable.Type: GrantFiled: November 25, 1980Date of Patent: May 31, 1983Inventors: Miklos Szabo, Vilmos Weiperth
