Abstract: The hydraulic transportation apparatus and method of the present invention incorporate a multiple chamber framework internally disposed preferably within at least one single shaft structure, which facilitates movement of object transport containers within the multiple chamber framework. Preferably, fluid elevation is employed to elevate and lower object transport containers and their contents within the multiple chamber framework. Each single shaft structure may be constructed from an existing rehabilitated shaft, or a newly drilled shaft. The present invention may be utilized in vertical or incline lifting environments, and an auxiliary hoist chamber may be incorporated into the multiple chamber framework for use as an alternative to, or in conjunction with, elevating objects by employing fluid elevation. The present invention may be employed in a variety of heavy lifting scenarios, including underground mining or in above ground lifting environments.

Abstract: An auger airlock assembly and end dump housing having a spring loaded bottom for use in a bulk loader which utilizes a source of negative pressure to create a suction air stream that draws particulate materials into the loader for transfer, via the auger assembly, to a location remote of the loader. Materials exiting the auger assembly accumulate within the housing to a point wherein, once the accumulated material has acquired a certain weight, the bottom of the housing is forced open to permit discharge of the material, and, once the material is removed, and is not present in enough quantity to maintain the bottom of the housing to remain open, the spring loaded connection biases the bottom back into a position sealably closing the housing. The bottom of the housing may also be opened by the auger feeding more material into an already full housing, whereby the material is compressed so as to force the door open.

Abstract: A pneumatic transport system including a user terminal at a service provider station having a movable member operably connected with a flexible drive member.

The user terminal includes control mechanisms on opposite sides of a base to enable two users to operate and access the carrier at the user terminal.

Abstract: A feeding system (10) for epoxy mould compound (EMC) pellets which has a supply bowl (12) situated outside the clean environment (24) of a conventional automatic moulding machine (26). A tube (16) extends from the supply bowl (12) to a buffer hopper (14) within the clean environment and which is located above the feeder bowl (28) of the automatic moulding machine (26). EMC pellets are transported through the tube (16) from the supply bowl (12) into the buffer hopper (14) via a vacuum suction system (34), (36) which is connected to the tube (16) in proximity to the buffer hopper (14). A counter air flow may be provided to slow the speed of the pellets as they enter the buffer hopper. Batches of the pellets accumulated in the buffer hopper (14) are periodically released into the feeder bowl (28) of the automatic moulding machine (26). The vacuum transportation system reduces dust from the pellets.

Abstract: A system (10) for carrying out transactions between a customer at a customer station (14) and a service provider at a service provider station (12), includes transferring a body (96, 140, 170) through a pneumatic transfer tube (26). The customer at the customer station provides inputs corresponding to a financial account through input devices on the body such as a card reader (72, 146, 172) and a keypad (74, 148, 172). Data input by the customer is stored in the memory (82, 158) on the body. After transfer to the service provider station, data in the memory is output to a charge device (56) which is operative to assess a charge to the customer's account responsive to data output from the memory.

A discharge manifold (18) separates the particulate material from air. A metering gate (70) is located at a base of a hopper (69), which controls the layer of particulate material deposited onto said conveyor. A second inlet manifold (26) and tubes (28) adjacent the receiving hopper entrains the particulate material in air. A receiving station (32) receives the particulate material from a second discharge manifold (30).

Abstract: The present invention provides a pneumatic transfer terminal adapted to receive and dispatch a non-captive, tubular article carrier of predetermined length from and to a single pneumatic transfer tube. The terminal includes a carrier receiver having the internal chamber dimensioned to receive an article carrier therein and to position the carrier in operable alignment with the transfer tube. The carrier receiver includes a first opening for communicating the chamber with the transfer tube and a second opening for insertion and removal of the carrier into and from the chamber. A blower assembly is attached to the transfer tube and is operable to create a vacuum therein. A gate mechanism is operable to open and close the second opening. The gate means includes a generally planar gate movable between a first position where the gate mechanism covers the second opening and a second position wherein the gate is removed from the second opening. An actuator connects the motor to the planar gate.

Abstract: A pneumatic transport system, particularly useful as a mail transport system, which includes a transport carrier moving through a pneumatic tube line between remote sending/receiving stations is described. Movement of the transport carrier through the pneumatic tube line is by means of a positive or negative air flow in the tube line provided by a blower means. The air flow direction is controlled by utilizing a series of adjustable valves, such as butterfly valves. The system additionally employs sensors for indicating the presence of the carrier in the exterior station.

Abstract: The present invention describes a stop device for stopping a carrier traveling in a pneumatic tube. The invention also includes a terminal comprising the stop device. The stop device includes a pneumatic tube having an exhaust aperture and a shutoff aperture and a pressure sensing monitor in fluid communication with the shutoff aperture. The pressure monitor senses the pressure change in the shutoff aperture caused by the carrier's movement past the shutoff aperture and activates a switch shutting off the pneumatic source. The carrier impacts an end stop and settles down on a catch which was also activated by the pressure monitor. The carrier is held in front of a door through which the carrier may be readily retrieved.

Abstract: Discharge apparatus for discharging broken-off fastener parts (such as the stems of blind rivets) from fastener installation apparatus, comprises a passageway (13) along which the parts (37) are conveyed away from the installation apparatus (11) by a flow of air generated by a vacuum pump (14). The end of the passageway (13) remote from the installation apparatus (11) is normally sealed against the entry of air by a discharge valve (16). A broken-off part (37) approaching the discharge valve (16) is detected by an approach sensor (34) which is connected by a latching relay unit (33) and a control valve (25) to actuate a pneumatic ram (22) to open the discharge valve (16). At the same time the vacuum pump (14) is turned off to prevent a reverse flow of air through the open valve (16). The part (37) is discharged through the valve (16) and into a receptacle (19) which is outside the vacuum system.

Abstract: A pneumatic tube system utilizes a carrier having at least one unlatched door which is biased to a normally open position but held closed by the conduit of the system. Access stations are associated with the conduit and permit the carrier doors to assume an open position upon reaching a station. A pneumatic system which can operate in either a pressure or a vacuum mode is activated automatically at the access station.

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.
