A signal transport system and a transport method are provided. A whole lowspeed signal containing a client overhead received from a client network is transparently subjected to time division multiplexing and an additional overhead is inserted in the whole signal and further subjected to wavelength division multiplexing, so that the digital signal having the addition overhead is transported in the wavelength division mode represented by one wavelength to a receiving equipment.

A low transport vehicle has a platform carried by a number of wheels arranged in a transverse row, hydraulic means being provided to raise and to lower the platform. In order to prevent a tilting of the cargo during voyage with the platform with respect to the wheels in raised position, the hydraulic system is arranged in such a manner that a ram operating an outward wheel in the row may be blocked-off from the system if the pressure in the system at the opposite end of the row falls below a pre...

A tape transport includes a fixed support for receiving a tape cartridge having a tape drive roller engaged with a bi-directional capstan. The capstan, together with a reversible capstan drive motor and a heat sink surrounding the motor, comprise an integral unit which is mounted to the cartridge support through biasing springs which enable the unit to pivot about its center of gravity relative to the support. The capstan, through its c.g. mount, applies a constant force to the tape drive roller...

A marine transport system encompasses at least three ports. A plurality of modular hold units are releasably engageable with any one of a plurality of vessels and are so sized that, when loaded with cargo, each hold unit consumes a substantial fraction of the load-carrying capacity of any one of the vessels. A dock facility is located in each port for supporting a hold unit, independently of any of the vessels, so that cargo can be worked into and out of the hold unit through at least one side o...

A transport vehicle providing for a light-weight frame structure including a plurality of transversely extending, longitudinally spaced divider members for supporting bulk cargo in individual bays, and with the loads and stresses being dispersed throughout the frame structure. The frame structure extends into a goose-neck connection for a tractive vehicle.

Method and apparatus for transporting lengths of film in a camera, particularly for taking pictures from a fluorescent screen, such as an X-ray screen. Using a single motor, the rate of transport is made independent of the rate of exposure, thereby allowing for maximum exposure times, permitting low radiation intensities.

A multipart, collapsible box for transporting small items being made of a folded sheet casing and two end elements. The casing is folded to form a bottom, side walls and inwardly extending flanges. The end elements are adapted to have the end edges of the casing to be fitted and secured therein. Each end element has two side portions, each with a projection to be fitted into a hole in the respective side wall of the casing for securing the end element to the casing. Guide bars are provided on th...

A transport container especially suitable to be supported on a cart or trolley, and also suitable for use in an aircraft, if desired, is constructed as a parallelepiped. Two oppositely located doors are connected by hinges to a frame structure. The hinges form part of the frame structure and allow the doors to open through an angle of 270.degree.. Corner braces having mutually perpendicular tenons mate with tubular metal stock such as sectional rods to form the frame of the container. The metal ...

A wheeled transport vehicle of the kind disclosed in my prior application Ser. No. 553,163 now U.S. Pat. No. 4,005,784, is provided with at least one laterally adjustable barrier member which forms a side or end of an interior space within which successive layers of bales or other articles are formed on or over the floor. A vehicle of the aforesaid kind has a body which is open at the back and comprises spaced side walls and a front wall and a vertically movable floor is arranged therein and is ...

A transport device comprising a pair of substantially identical dolly devices for moving hospital beds and the like. Each dolly device comprises an elongated base plate having a pair of swivel mounted casters or wheels attached to the lower surface thereof and an attachment member disposed on the upper surface thereof configured to operatively engage and secure the hospital bed thereto.
