Abstract: A conveyor system has a pair of outer wheel tracks and a pair of inner wheel tracks, the wheel tracks of each pair being spaced from each other and extending parallel to each other. Each wheel track has at least one generally vertical portion and at least one generally horizontal portion. A conveyor member has two pairs of wheels, the wheels of each pair being located on opposite sides of the member, each pair of wheels engaging one pair of wheel tracks; the wheels and tracks are configured and oriented relative to each other so that the member is maintained in a selected orientation as the member moves relative to and along the tracks. The conveyor system includes a lift subsystem for preventing slippage of the conveyor member as the conveyor member travels around a curved portion of the conveyor system.

Abstract: A pneumatic transmission system having a carrier automatic braking system contains a transport conduit having a first end and a second end and being capable of permitting the transfer of a carrier therethrough, a first station for sending and receiving a carrier located on one end of the transmission conduit, and a second station for sending and receiving a carrier located on the other end of the transmission conduit. A motor blower, capable of moving a volume of air through a conduit, is enclosed within a supply/exhaust branch which is connected to one of the stations. A valve, capable of closing, to thereby create an air block in the supply line, is also disposed within the supply/exhaust branch. The motor blower blows air to move the carrier from one station to the other. The valve is activated, after deactivating the motor blower, when the carrier is detected at some predetermined location along the transport conduit.

Abstract: A pneumatic transmission system having a carrier automatic braking system contains a transport conduit having a first end and a second end and being capable of permitting the transfer of a carrier therethrough, a first station for sending and receiving a carrier located on one end of the transmission conduit and a second station for sending and receiving a carrier located on the other end of the transmission conduit. A pair of motor blowers, each capable of moving a volume of air in opposing directions through a conduit, are enclosed within a supply branch which is connected to one of the stations. The first motor blower blows air to move the carrier from one station to the other. The second motor blower is activated, to operate concurrently with the first motor blower, when the carrier is detected some predetermined location along the transport conduit.

Abstract: A tape conveyor system for moving a carriage along a path having at least one vertical curve and at least one horizontal curve comprises a carriage track, a tape guide, and a carriage. A block on the tape is movably positioned between two elements on the carriage to effect movement of the carriage along the carriage track. The tape guide orients the tape width horizontally during each vertical curve and vertically during each horizontal curve. The carriage track has two opposing channels, and the carriage has wheels in each channel so that the carriage can move along both horizontal and vertical track portions in a stable manner. A container can be mounted to the carriage via a leveling mechanism which cooperates with cam guide surfaces on the carriage track to control the orientation of the container.

Abstract: A pneumatic transport system includes a pneumatic transport tube having a stop device mounted therein. A window aperture is defined through a wall of the transport tube such that a pneumatic tube carrier is presented for retrieval through the window aperture upon its arrival. A pneumatic pressure source is provided to cause the carrier to move through the transport tube.

Abstract: A pneumatic transmission system is provided. The system comprises a transmission tube having a first end and a second end. A blower adapted to force air from the first end to the second end of the transmission tube is interconnected to the first end of the transmission tube. A vacuum source having a capacity at least as great as that of the blower is connected to the transmission tube proximal the second end. The vacuum source creates a flow of air from the second end of the transmission tube to the vacuum source, thereby decelerating a carrier being transmitted to the second end of the transmission tube.

Abstract: A pneumatic transmission system adapted to send a carrier from one terminal to a second terminal with apparatus to control the free delivery of the carrier to a terminal comprising a check valve to relieve pressure behind a carrier once it has passed a check valve and an adjustable air valve to control the negative pressure ahead of the carrier to control the free delivery of the carrier from the end of the transmission tube in a single tube reversing system with negligible amount of air being taken into or discharged from the open terminal.
