Abstract: A method for transporting a substrate is provided. In this method, a non-Newtonian fluid is provided and the substrate is suspended in the non-Newtonian fluid. The non-Newtonian fluid is capable of supporting the substrate. Thereafter, a supply force is applied on the non-Newtonian fluid to cause the non-Newtonian fluid to flow, whereby the flow is capable of moving the substrate along a direction of the flow. Apparatuses and systems for transporting the substrate using the non-Newtonian fluid also are described.

Abstract: A pneumatic mail delivery system includes a carrier having first and second open ends and corresponding hinged covers for selectably covering the open ends. The system includes first and second carrier terminals each having front openings selectively covered by hinged doors. The terminals may be positioned at a mail deposit location and a residential location. A pneumatic conduit connects the terminals through which the carrier may be guided therebetween. The conduit is connected to a blower for conveying the carrier. Spring-biased buttons attached to respective terminals are electrically connected to the blower for actuating the blower upon detecting a closure of a respective door. A photoelectric light sensor is attached to each terminal and is electrically connected to a light source mounted on the front of each terminal. Respective lights are energized when a respective light sensor detects mail in the carrier.

Abstract: A fluid pumping assembly for pumping particulate material includes a pump housing defining a pump cavity including a pumping chamber for handling particulate material, a motive fluid chamber, and a moveable diaphragm. The fluid pumping assembly also includes devices for loading particulate material into the pumping chamber, and for injecting a high pressure, high volume purging fluid into the pumping chamber. Further, the fluid pumping assembly includes a control system having a control valve for shutting off flow of high pressure, high volume purging fluid into the pumping chamber when particulate material is being loaded into the pumping chamber, thus enabling dense phase loading of particulate material, and thereby optimizing a particulate material pumping capacity of the fluid pumping assembly.

Abstract: An apparatus for feeding product to a pipeline via a venturi assembly has first and second tanks adapted to separately hold a quantity of product. The product is fed to the tanks from a supply hopper and enters each tank through an upper opening which accommodates a feed chute. The open end of each feed chute is closable by a flapper door which is swingable between open and closed positions. Pressurized air from a compressor is used to selectively close the flapper doors via a set of pressure valves which control the flow of air into the tanks. The product is fed from each tank to the pipeline through a Y-shaped housing and the venturi assembly. The housing has respective lower openings for each tank, also closable by swingable flapper doors. When the upper doors are closed by the air pressure, the product is forced out of the tank into the pipeline.

Abstract: A simplified construction of a customer terminal for a single conveyor tube visual banking service pneumatic tube system to which a teller terminal also is connected. The customer terminal has a cylindrical carrier-receiving pocket extension connected to the system tube. The pocket is formed by two molded plastic members, one fixed in the terminal cabinet and one a door. The members are hinged together so that the door may be opened for carrier placement or removal through a fixed member opening which provides access to the pocket when the door is opened. The door is biased open and is closed manually which automatically locks the door closed and pressurizes the system to send a carrier from the terminal. A carrier delivered to the terminal during system vacuum operation automatically opens the door. The system airflow terminal connection provides an air brake effect to abruptly arrest carrier movement avoiding noise and shock.

Abstract: A banking service pneumatic tube system teller terminal having a single conveyor tube. A carrier is transported in the system and is removable from the terminal housing formed of molded plastic material. The housing may be installed for carrier arrival vertically from above or below. The housing has an access opening closed by a cradle-door movable between open and closed positions. The cradle has a cylindrically walled carrier receiving compartment located between cylindrical end portions of the housing when the door is closed. One housing end portion is coupled with an end of the system conveyor tube. A carrier arrival switch is mounted on the cradle actuated by carrier arrival to automatically open the door by release of latch mechanism mounted on the cradle which normally locks the cradle-door in closed position. A carrier is presented in the cradle outside of the housing when the door opens. The cradle-door is manually closed, automatically actuating the latch mechanism to lock the cradle-door closed.

Abstract: A customer terminal for a single conveyor tube banking service pneumatic tube system. The terminal has a cabinet which can be opened by unlocking and removing a hinged front member to expose system components and terminal mechanism. The carrier receive and send housing has a hinged door and the housing communicates with the system conveyor tube. The mechanism is operative automatically to present a carrier arriving at the terminal to a customer seated in an adjacent vehicle. The presented carrier is conveniently positioned at an angle at the outer end of a pocket on the door for removal and replacement by a customer without requiring precise positioning. The carrier is returned automatically to the conveyor tube system when replaced in the door pocket. The door has safety mechanism automatically reopening the door if it encounters an obstacle on closing.
