Abstract: A golf ball is provided with evenly and uniformly distributed dimples so that at least four great circle paths on the surface of the golf ball do not intersect any dimples. The spherical surface of the golf ball is divided into fourteen geometric shapes, comprising six spherical squares and eight spherical hexagons. The arrangement of the dimples on the spherical surface is generally defined by the sides of the spherical squares and hexagons. The uniform distribution of dimples and great circle paths is such that the golf ball displays multiple axes of symmetry.

Abstract: A device for metering a fluid product comprises a closure cap threaded onto the nack of a container and acting on the stem of a valve member to lift the latter of a seat formed at the lower end of a cylindrical wall fixedly inserted into the neck of the container against the action of a resilient member.A metered dose of the product is dispensed by turning the container upside down and unscrewing the closure cap by then filled with the metered dose.In the inverted position the fluid product contained in the container flows into a chamber defined by the cylindrical wall via the opened valve member and a passage associated to the resilient element. The flow of the fluid product into the chamber is stopped by the engagement of the valve member with its seat as the closure cap is being unscrewed.In another embodiment, an intermediate element having a screw-threaded neck portion and a seat for the valve member is secured to an annular rim of a container.

Abstract: An electrically operated firing piston is provided for effecting the firing of a perforating gun in a subterranean well. The electrical firing system is disposed within a hollow housing which is detachably secured to the gun and is subject to the fluid pressures surrounding the perforating gun. The electrical firing system is armed through the application of a fluid pressure to the exterior of the housing which is in excess of the well hydrostatic pressure, thereby preventing premature firing of the perforating gun before insertion at its desired position in the well. The generation of an electrical firing pulse is controlled by a microprocessor which is preset to be responsive only to a selected value of fluid pressure surrounding the control housing. Thus, the pressure surrounding the perforating gun may be reduced to a selected under-balanced condition before the firing of the gun can be effected.

Abstract: A combined cycle waste-to-energy plant is utilized to thermally convert municipal and industrial solid wastes into essentially complete products of combustion and use the combustion heat to produce steam and/or electrical power. The plant includes a building enclosure having a waste receiving area, a waste fuel separation and processing area, an incinerator area and a heat recovery and power generation area. Processed waste fuel is delivered to a series of incinerators by an automated conveyor and hopper system, and the waste fuel is burned in the incinerators by hot exhaust gas delivered thereto from one or more combustion turbines located outside the building and drivingly connected to electrical generators. Inlet air to the turbines is drawn from with the building to maintain its interior at a negative pressure, thereby preventing waste odors and pathogens from escaping from the building.

Abstract: Disclosed is a nestable bed. The bed includes a rectangular frame adapted to receive a mattress. The frame has a longitudinal axis and a transverse axis. A pair of first legs are mounted to a first end of the frame with the legs lying in a plane perpendicular to the longitudinal axis. A pair of second legs are mounted on opposite sides of the frame with the second legs lying in spaced apart planes perpendicular to the transverse axis of the frame. The first and second legs are skewed or canted such that substantially identical beds may be nested on top of each other with their sides and ends coincident. Rollers are mounted to the first legs such that the bed may be stood on end and rolled about.

Abstract: A separable fluid pressure activated firing mehanism for a perforating gun comprises a pressure-operated tubing valve, a packer, and a tubular housing assembly defining a plurality of fluid pressure chambers therein. The first chamber contains a light density, clean, compressible fluid which is subject to well annulus pressure above the packer to provide a reference pressure. A second chamber sealably mounts a piston-type firing pin, which is normally secured by a locked latch in an elevated position above a detonatable primer and the lower portion of said firing pin is exposed to the reference pressure. The latch is unlocked through the application of a predetermined annulus pressure above the packer to a locking piston which moves to unlock the latch and trap the reference pressure in the first chamber. A further increase in said annulus pressure opens the tubing valve.

Abstract: A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by flow restrictive passages formed in the piston or in the cylinder wall. When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through the restrictive passages resulting in heating of the fluid. When the strut rebounds or extends its piston rod fluid is forced to flow through the restrictive passages preferably at a more restricted rate.

Abstract: An air impingement tunnel oven is provided for very rapidly and evenly cooking food items carried horizontally through the tunnel on a suitable conveying mechanism. The oven is provided with upper and lower plenum ducts which are positioned in a vertically spaced relationship within the tunnel so that food items traversing the tunnel pass between them. Vertically facing wall portions of the plenum ducts have cross-sections which are defined by alternate series of generally V-shaped ridges which respectively project toward and away from the interior of their plenum ducts and extend generally perpendicular to the direction of food item travel within the tunnel. A series of rectangular air slots are formed in apex portions of the ridges which project away from their plenum duct interiors. Separate fans are utilized to supply heated tunnel air into the plenums in a direction generally parallel to the ridges therein, the ridges functioning to facilitate even air distribution to the air slots.

Abstract: A subterranean well casing float tool is comprised of a tubular metal housing which is securable to a well casing conduit. Varing means are implaced within the housing, with substantially all of the components of the valving means, save a biasing means, are thermosetting. The valving means has a thermosetting frame and valve head and valve seat means relative to the frame. A biasing member, such as a compressed spring is used for urging the valve head toward the valve seat to a closed position. A compartment including the valve head is provided for enclosure around the biasing means when the valve head is moved fully away from the valve seat to protect the spring from errosive turbulent fluid flow when the valve head is in the open position relative to the seat. The valving means is directly secured to the housing by means of thread members having profiled shear surfaces such that the shear area of the valving means is substantially greater than that of the metal housing.

Abstract: A catamaran boat comprises two pontoons which are rigidly interconnected in laterally spaced relationship by a plurality of transverse beams. An air guiding sheet is rigidly connected to the bottom surfaces of the transverse beams and defines an air tunnel extending above the water between the two pontoons. The air guiding sheet is upwardly curved at its forward end and is provided with one or more transversely extending downwardly projecting ribs or bulges which result in a compression of the air in the tunnel when the boat is moving through the water. This substantially increases the lift exerted on the boat, permitting it to ride at a higher level and achieve higher speeds. The inner vertically extending walls of the spaced pontoons are disposed at an angle to the vertical, with each inner wall extending outwardly toward the outer wall by a slight angle. This configuration permits the boat to traverse shallower waters than has been heretofore possible with catamaran type boats.

The treatment fluid comprises an acidic injection medium and an acid corrosion inhibitor. The intensifier is introduced into the fluid for deposition on or effective treatment contact with the high alloy steel. A method of inhibiting acidic corrosion and a method of treating a subterranean well for enhanced production also are disclosed.

Abstract: An improved rotor-type carburetor for use with an internal combustion engine is provided which, in one embodiment, is adjustable to selectively vary its constant fuel-air ratio by axially moving an internal body portion thereof relative to the turbine rotor assembly of the carburetor. Alternatively, the constant fuel-air ratio of the carburetor may be altered simply by replacing such internal body portion with a differently configured one. Undesirable fuel delivery from the turbine rotor to the engine during turbine spin-down is significantly diminished through the use of an internal fuel reservoir structure, formed within the carburetor body, which functions to capture and retain unneeded fuel discharged from the rotor during turbine spin-down periods. During turbine spin-up periods (e.g., when the engine is being started) the reservoir-retained fuel is released into the engine's incoming air stream to hasten fuel delivery to the engiune during initial portions of turbine spin-up periods.
