A height-adjustable table with concealed wiring design is provided herein, which includes table surface, table leg, table foot, driving mechanism, and control device. The table leg is connected between the table surface and the table foot and includes a telescoping tube structure. The driving mechanism includes motor, first threaded rod, and connecting tube. The first threaded rod screwed to one end of the connecting tube and the connecting tube are disposed in the telescoping tube structure. The motor is configured to drive the first threaded rod to alter the length of the telescoping tube structure. The control device includes wiring and a control interface. The wiring is disposed in the telescoping tube structure and spirals around the connecting tube. The wiring transmits power to the driving mechanism and transmits a control signal from control interface to the motor to drive the driving mechanism.

A gangway connection system guides at least one power cable and has a clamping part which has at least one feed through for the power cable. The feed through extends along a longitudinal axis and between an inlet opening and an outlet opening, and has a longitudinal-section profile with an inner and an outer longitudinal-section contour. At least one of the longitudinal-section contours is curved at least regionally. Alternatively or in addition, the gangway connection system is characterized in that the power cable extends helically in a cable longitudinal direction and the clamping part has an outer face directed in the cable longitudinal direction. The clamping part has at least one abutment surface for the power cable. The abutment surface extends in an inclined manner with respect to the cable longitudinal direction.

Systems and methods according to one or more embodiments are provided for providing a durable and thermally insulated duct network. A duct network may be provided by coupling two or more foam ducts to each other. In one example, a system includes a plurality of foam ducts and a plurality of foam bellows configured to couple the foam ducts to each other. The foam bellows include one or more bellow folds to allow an expansion and contraction of the foam ducts. A plurality of structural fastening systems couple the duct network to a structure of a vessel. The structural fastening systems allow for an axial movement of the duct network as the foam ducts expand and contract. Additional systems and methods are also provided.

A retractable boom pole disclosed herein has a telescoping pole with hollow interior. A cable running at least substantially a length of the telescoping pole is centrally situated within the hollow interior at least substantially the entire length of the telescoping pole. A retraction mechanism (such as a spring-loaded or electrically powered motor device causing rotation of a spindle within the hollow interior) situated within a housing connected to the telescoping pole, causes the cable to be retracted as the telescoping pole is shortened in length. An electrical outlet or port situated within the housing is electrically coupled to the cable.

A mining machine includes a boom having an interior chamber, a saddle block coupled to the boom, a handle slidably coupled to the saddle block, and a reel system disposed at least partially within the chamber.

A pipe support system includes a pipe base, a threaded bolt having a head, a deck supported above the pipe base, and a cap removably resting on the upper surface of the deck. Methods for installing the pipe support system include determining a height of a joint of pipe or pipe component above a ground surface; selecting a length of the pipe base in accordance with the height of the joint of pipe or pipe component above the ground surface; slidably placing the bolt into an inner diameter of the pipe base until a flanged housing is landed onto a top of the pipe base; rotating the head of the bolt relative to the pipe base in order to provide micro-adjustments to the height of the deck relative to the pipe base; and placing the joint of pipe or other pipe component onto the cap, thereby supporting the pipe component above the surface.

A fluid supply system includes: fluid lines, fluid controllers and joints, in which each of the fluid lines linearly extends in an extension direction that substantially perpendicularly intersects an alignment direction of the fluid lines, each of the fluid controllers is disposed in an aligned manner in the alignment direction with connection surfaces directed to the same direction, a diameter of the pipings is equal to or less than a surface width of the connection surfaces in the alignment direction, and diameters of the joints are equal to or greater than the surface width, and the pipings that are adjacent to each other in the alignment direction are positioned with the joints displaced from each other in the extension direction.

A snorkel for guiding cables and tubes of the present teachings can include a base having an entrance and a conduit interface. The entrance can be configured to guide cabling into the conduit interface. The snorkel can include a conduit operably coupled with the base. The conduit can include a cap interface, and the conduit can receive the cabling through the conduit interface. The conduit can be configured to lower and raise within the base. The snorkel can include a cap operably coupled with the conduit. The cap can include a cable exit cavity and a tubing guide ear.
