  • Patent number: 8556540
    Abstract: A deployment and retrieval apparatus for ocean bottom seismic receivers, the apparatus being a remotely operated vehicle (ROV) having a carrier attached thereto and carrying a plurality of receivers. The carrier includes a frame in which is mounted a structure for seating and releasing the receivers. The structure includes one or more movable conveyors disposed to move receivers along a linear path relative to the frame in order to discharge and retrieve ocean bottom seismic receivers.

  • Patent number: 8075226
    Abstract: A deployment and retrieval apparatus for ocean bottom seismic receivers, the apparatus being a remotely operated vehicle (ROV) having a carrier attached thereto and carrying a plurality of receivers. The carrier includes a frame in which is mounted a structure for seating and releasing the receivers. The structure may include a movable conveyor or fixed parallel rails or a barrel. The structure includes a discharge port on the frame and a discharge mechanism for removing and retrieving the receivers. A method for deployment and retrieval of ocean bottom seismic receivers includes the steps of loading a carrier with a plurality of receivers, attaching the carrier to an ROV, utilizing the ROV to transport the carrier from a surface vessel to a position adjacent the seabed and thereafter utilizing the ROV to remove receivers from the carrier and place the receivers on the seabed.

  • Patent number: 7644841
    Abstract: A manually operated dispenser of the type containing a diaphragm at the bottom of the bottle, such that when the diaphragm is compressed a quantity of fluid is dispensed above the bottle through a spout. This invention uses a unique diaphragm shaped like a blister, that is integrated into the bottle bottom with a slide-pin allowing the blister diaphragm to move up and down, but not side to side. The diaphragm seals to the bottle bottom during dispensing, but when the diaphragm is substantially compressed, the seal self breaks as the diaphragm edge expands radially from the diaphragm axis over bumps on the bottle bottom allowing the diaphragm to refill. At the fluid output of the spout is a channel valve nozzle that channels the fluid into a stream when the fluid flows, but when the fluid is not being dispensed, prevents fluid from flowing back into the bottle.

  • Publication number: 20080029560
    Abstract: The invention comprises of a two wheeled seed spreader having a centrally located box for storing the seed. The box has surrounding sides and an open bottom. A conveyor belt is mounted across the open bottom for conveying seed in the box forward to the front bottom of the box, an adjustable brush is mounted above the forward end of the conveyor and adjustable downward against the belt to vary the amount of seed conveyed off the forward end of the belt. A rotary brush is mounted just in front of the forward end of the belt and driven counterclockwise and downward against the belt to drive seed traveling off the forward end of the belt downward toward the ground.

  • Patent number: 6938655
    Abstract: A septum for chemical containers comprises a body, a first port through the body having a first interior diameter sufficient to permit a flow of a fluid through the first port, and a second bore through the body having a second interior diameter less than the first interior diameter. The second interior diameter is sufficiently small as to restrict passage of vapors evaporated from within the container. In this configuration, vapors are safely exhausted outside a work facility, and a chemical container that would be classified as Use-Open under applicable fire codes is converted to Use-Closed, enabling the work facility to increase the volume of chemicals that may be contained or used in the facility under the code, without upgrade to Hazardous Occupancy standards, or building new facilities that qualify as Hazardous Occupancy and that can use Use-Open chemical containers.

  • Patent number: 4767063
    Abstract: An adaptable material-spreading vehicle includes in combination a truck body frame, an engine mounted on the frame, a cab mounted in a forwardly positioned cab region, a removable hopper positioned behind the cab region, and a conveyor running from beneath the hopper directly through the cab region to a forwardly mounted material spreader with the hopper and conveyor being removably mounted to the truck frame, such that the material spreader vehicle can be converted to some other use. In one embodiment, the cab is provided with a central channel through the floor to accommodate the section of the conveyor passing through the cab region, with the cab being provided with sealable conveyor ports aligned fore and aft through which the cab-carrier conveyor section is passed.

  • Patent number: 4212428
    Abstract: A trailer-type vehicle for transporting and dispensing solid materials over the ground includes a self-contained, hydraulic power and control system driven by one of the vehicle's ground engaging wheels which operates a first dispensing mechanism at a selectable speed proportional to the vehicle's rate of travel over the ground, but operates a second dispensing mechanism at a constant speed regardless of the vehicle's rate of travel. A single hydraulic motor driven by a selectively engageable drive train connected with one of the vehicle's wheels is novelly employed as a hydraulic pump for delivering a force transmitting fluid through a pair of control valves to a pair of hydraulic motors respectively powering the dispensing mechanisms. One of the control valves includes provision for selectively adjusting the flow rate to the associated hydraulic motor thereby allowing adjustment of the volume of material being dispensed per area of ground covered by the vehicle.
