The inverted inventory bin is moved onto a conveyor and the inventory bin lifted thereby leaving the inventory items on the conveyor.

Abstract: The invention relates to a Surf Pool wherein a portion of the beach is provided with a wave catch basin. With the wave catch basin extending along the length of the beach, the wave catch basin will allow water to go over an infinity edge and settle in the wave catch basin, wherein wave energy backflows are eliminated and rip currents are avoided. With the wave catch basin extending along the beach side of the surf pool, the water that is collected in the wave catch basin and by pumping water out of pipe fittings or creating positive suction into pipe fittings, alters the flow of the rip current, thereby altering the wave formation characteristics. As the rip currents enter the rip current flow channels on both sides of the surfing reef, water can be suctioned down through return pipes or pumped in any direction along the surf pool bottom to stop the rip currents in the rip current flow channels, which helps the breaking waves from becoming distorted as they break.

Abstract: An improved device for discharging water that is capable of efficiently generating an effective wave-like motion within a body of water. Wave generation devices based on water filled elongated tubular chambers having a substantially closed rear end and a substantially open front end and using compressed air to discharge water, such as the wave cannon, may experience operational inefficiencies from variations in quantities of compressed air. Reducing the quantity of compressed gas may result in ineffective waves and damage to the elongated tube as internal low pressure conditions collapse. A source of make-up fluid configured to mitigate internal low pressure conditions can enable effective wave generation with reduced quantities of compressed air.

Abstract: A truck including a container used to transport and dispense loose particulate materials. A moving floor is located on the floor of the container to move loose particulate materials within the container into a feeder and dispensing system. The container includes two opposing augers mounted on the inner surface of a rear door of the container. The augers feed loose particulate material within the container to a mixer. The mixer helps to break up the loose particulate material to keep it from bridging as it drops into a feeder. The feeder regulates the flow of loose particulate material into a mixing chamber. A high volume air blower is connected to the mixing chamber. The blower forces a high volume of air through the mixing chamber and out of the mixing chamber into an attached hose. As loose particulate material drops into the mixing chamber, it mixes with the air flow and is blown out of the attached hose.

The new method eliminates the labor intensive prior method of wheelbarrowing sand or gravel from the off-load site to the selected site and the need then to rake or hoe the sand or gravel to properly spread it about the selected area.

Abstract: The specification discloses an apparatus for harvesting vegetables such as onions, including a topping plenum and a root cutting bed. Onions are removed from the ground by a self-adjusting digger conveyor which conveys them to an elevator conveyor. The elevator conveyor rises steeply over the large diameter, wide tires which convey the apparatus through the field. From thence the onions are conveyed beneath a vacuum plenum through a first air flow zone which is baffled so that the air flow is just sufficient to raise the tops of the onions off the conveyor and then through a second air flow zone where the onions are actually lifted off the conveyor and into registry with a registering and cutting means which cuts the tops off the onions. From thence they drop onto a root cutting bed which removes the roots of the onions and conveys them to a bulk loading conveyor. Dirt and offal drawn into the vacuum fan are conveyed out of the vacuum fan housing by a continuous conveyor system.

The conduit tangentially enters a vacuum chamber which is connected to a vacuum source.

This acceleration increases the distance between cups and permits sufficient time for their individual removal. In a practical apparatus, the accelerating device is an air nozzle to apply pressurized air along the conveyor and push along the cups.

Abstract: An underground mining method and apparatus which utilizes at least first and second spaced-apart shafts extending essentially downwardly into the earth and at least one lateral opening connecting the two shafts at a location below the earth's surface. An empty ore carrier is dropped into a first of said shafts and allowed to gravitationally fall towards the bottom of said shaft, its rate of descent being controlled by regulating the flow of air out of the bottom of said shaft. When the empty ore carrier reaches its stopping point in the first shaft, the carrier is transferred into the lateral opening filled with ore, then into a watertight compartment which is sealed and filled with water, and then into the second water-filled shaft. The ore-bearing carrier then floats to the earth's surface, is emptied, and returned empty to the first shaft for a repeat of the above procedure. Several carriers are kept in service at the same time.

In one embodiment, the air track member extends between a pair of holders which respectively supply and receive discs carried by the track member. The discs may be carried to a predetermined fixed point, released, and subsequently retrieved from the same position.
