  • Patent number: 8844615
    Abstract: A mechanism for pressurized delivery of material into a well without exposure to a high pressure pump. The mechanism may include material delivery equipment that is coupled to the high pressure pump or other pressure inducing equipment through a material carrier that intersects a fluid line from the pump. The material carrier may include chambers that are reciprocated or rotated between positions that are isolated from the fluid line and in communication with the fluid line. While isolated from the fluid line, the chambers may be filled with oilfield material which may then be delivered to the fluid line when positioned in communication therewith. In this manner, a supply of the oilfield material may be retained in a substantially isolated state relative to the pump and components thereof which may be susceptible to damage from exposure to the oilfield material.

  • Patent number: 7144213
    Abstract: An apparatus and method for controlling the flow of a process material from a higher pressure environment to a lower pressure environment is provided. Each of a first and second chamber is divided into a product region and a control region by a flexible boundary. Inlet and outlet flow control devices provide fluid communication between each product region and a material input line and a material output line, respectively. A chamber control device is arranged to provide fluid communication between the control region of each chamber, which is filled with a non-compressible fluid. As product fills the product region of one chamber, fluid is displaced from the corresponding control region and into the control region of the other chamber. As the control region of the other chamber expands, product is forced out of the corresponding product region and into the material output line. The product region of each chamber is alternately filled and emptied to produce a continuous transport of material.

  • Patent number: 6575347
    Abstract: A rivet feed slider configured to sequentially receive rivets from a rivet delivery path and feed the rivets to a rivet transport tube using an air supply. The rivet feed slider includes a rivet receiving chamber which is configured to sequentially receive the rivets, and an aperture is in communication with the rivet receiving chamber. The aperture allows air to flow from the air supply through the rivet receiving chamber to the rivet transport tube such that a rivet which is disposed in the rivet receiving chamber is moved into the rivet transport tube. The rivet feed slider also includes additional apertures which allow air to flow from the air supply to the rivet transport tube when the rivet receiving chamber is not aligned with the air supply. Hence, the air flow from the air supply to the rivet transport tube is not substantially disrupted.

  • Patent number: 6461085
    Abstract: A sputter pallet loading and unloading device includes in one embodiment a spindle that rotates the pallet while an arm is engaged with the spring in the pallet to open and close the spring. In another embodiment, the spindle is located adjacent an air track that moves the disk substrate over a cushion of air to the loading area of the pallet. The air pressure under the disk substrate is increased to raise the disk substrate into the loading area. Once raised into the loading area, the spring is closed, e.g., by rotating the pallet in the opposite direction. The pallet and air-track are at a small angle to allow the substrate to slide into the correct position. The simplicity of operation leads to a reduced cost and a higher throughput for this device compared to a robotic loader.

  • Patent number: 5356243
    Abstract: A downsend terminal for a pneumatic transport tube system has a pivoting tube section pivoting about an upper horizontal axis to move the pivoting tube section between a first vertical position and a second oblique position. When at the oblique second position, the carrier is dropped out of the pivoting tube section onto a carrier support holding the carrier in a generally vertical position for access to the user. When the user completes the transaction, the terminal pulls the carrier vertically back into the pivoting tube section. If the carrier is overloaded, there is insufficient force to lift it off of the carrier support, and therefore an overloaded carrier is prohibited from entering the transport tube system. In addition, the construction prevents debris and other material from entering the transport tube system.

  • Patent number: 4661026
    Abstract: A pneumatic tube send/receive terminal has a dispatch carrier that is movable between a load position and a send position. A sprocket chain fits on two sprockets and rotates under motor power, and a cam is mounted on the chain. A clapper valve or cover is hinged to a trolley or carriage that also rotatably holds the dispatch holder. A block or cog attached to the chain connects to the dispatch holder, and this rotates the same 180 degrees and then moves the trolley and the dispatch holder laterally to the send position. The cam rides a camway on the valve, and normally holds it shut, but when the chain is moved, the cam rotates over the camway and releases the valve so that it opens, and any received pneumatic carrier drops out. Rotation of the dispatch holder 180 degrees prevents inadvertent accessing the pneumatic tube with a second carrier in a single send operation.

  • Patent number: 4620656
    Abstract: This system selects and delivers a rivet of correct size for workpiece thickness at each rivet location. Positive control of rivet orientation is provided at the crucial junction point of plural supply paths with the delivery path to the riveting machine. This is done by a simplified modular device, called a "transfer station," which hands off one rivet from the correct supply path to the delivery path, on demand by a measuring device. Positive rivet-orientation control is also provided everywhere else in the system, including the escapements and the injector--making it feasible to use a pneumatic tube for delivery to the injector. Thus only the measuring device and injector need be mounted to the installing head of the riveter. Orientation at the escapement is fixed by a dual-blade mechanism that constrains each rivet shank, keeping the rivet from toppling head-first into a pneumatic supply tube to the transfer station.
