Filed:

Feb 12, 2010

Appl. No.:

12/705159

Inventors:

Carroll G. Rowe - Washington AR, US

International Classification:

F16K 31/12
F16K 31/36

US Classification:

137508, 137505, 13750525, 13750528, 137488, 251 635

Abstract:

A pressure regulator is capable of automatically regulating the inlet water pressure to a compressed air foam system (CAFS), thereby allowing direct connection between a high-pressure water source, such as a hydrant, and the CAFS. The pressure regulator includes an inlet, a valve that regulates flow from the inlet, and an annular piston that circumscribes the inlet and which is linked to the valve. The relative area of the inlet and the piston determine the maximum pressure that may be attained at the CAFS water inlet, due to pressure on the piston forcing the valve closed.

International Classification:

B60P 104

US Classification:

214353

Abstract:

A device upon which a cylindrical bale of hay or any other appropriate commodity may be loaded and transported including a carrier frame, hitch frame which is pivotally connected to the front of the carrier frame, axle and wheels which are connected to the carrier frame, braking means for the axle and wheels, a fork which is pivotally connected to the carrier frame and is used to pull the bale onto the carrier frame, and a limiting strap which is attached to the carrier and hitch frames for stopping and maintaining the carrier frame in an upright position when the bale of hay has been loaded upon said frame.

Inventors:

Carroll G. Rowe - Washington AR

International Classification:

B01F 304

US Classification:

261 181

Abstract:

Apparatus for generating foam for use in fire fighting having two plates housed in a chamber which respectively introduce pressurized air and a water/surfactant solution between the two plates where foam is generated and emitted from an aperture on the side of the chamber. The pressurized water/soap solution enters the chamber through an orifice in one plate. Pressurized air enters the chamber through a number of channels bored through the other plate, such channels appearing in an annular groove which circumscribes the water inlet. The plates are provided with surfaces which are brought together to form a restricted area therebetween. The restricted area balances the pressure between the incoming water and the incoming air by achieving an equilibrium at some particular radius out from the center of the two plates. This equilibrium radius moves in and out from the center as necessary to keep the two pressures balanced. The apparatus also includes a pressure regulating system that automatically cuts off the flow of pressurized water and air when the foam dispensing nozzle is turned off.

International Classification:

A01D 7814

US Classification:

56 159

Abstract:

A hay rake moveable between a rake position and a transport position. A frame assembly supported by an axle and wheels carries two sets of fingerwheel hay rakes which are rotatable on an axis positioned transversely to the axle. A hitch assembly which is connected to a towing vehicle is pivotedly connected to the frame. A connecting linkage is provided between the hitch assembly and the frame and a power source is connected to the frame for rotating the wheel rakes about their axis and rotating the frame relative to the hitch assembly thereby rotating the rakes between a downward and outward rake position and an upward and inward transport position.

International Classification:

US Classification:

Abstract:

Apparatus for generating foam for use in fire fighting having two plates housed in a chamber which respectively introduce pressurized air and water/soap solution into the space between the two plates where foam is generated and emitted from an aperture on the side of the chamber. Pressurized water/soap solution is introduced through an orifice into a small opening through one plate. Pressurized air is introduced into the other plate through a number of channels bored through the plate to an annular grove on the surface of the plate. The plates are provided with flat surfaces which are brought together to form a narrow gap. The narrow gap balances the pressure between the incoming water and the incoming air by achieving an equilibrium at some particular radius out from the center of the two plates. This equilibrium radius moves in and out from the center as necessary to keep the two pressures balanced. The incoming air pressure is set at a desired level, and the incoming water pressure is adjusted to a slightly higher initial pressure.

US Classification:

56377

Abstract:

A hay rake having a frame assembly, having a front, a back and two sides and supported by wheels for being moved by a vehicle. A first and second set of a plurality of fingerwheel rakes are provided with each set rotatably carried adjacent opposite sides of the frame about a separate axis. Each of the axis are at an angle to vertical and horizontal. A power actuator on the frame rotates the rakes about the axis for rotating the rakes downwardly, outwardly and backwardly for moving the rakes to a rake position and rotates the rakes upwardly, inwardly and forwardly to raise the rakes to a transport position.
