A movement-tolerant wiring arrangement for, among other things, a stand device configured for arrangement in an operating room incorporates a mounting apparatus for movement-tolerant mounting of at least one line, for example a cable, about an axis of rotation between two connection components that are displaceable, such as being twistable, relative to one another; and a fastening apparatus for arranging the at least one line relative to one of the connection components, for example at a socket of the stand device; wherein the mounting apparatus is fixable to the fastening apparatus and configured for movement-tolerant, such as, rotation-tolerant guidance of the at least one line about the axis of rotation and/or in the direction at least approximately parallel to the axis of rotation. Furthermore, a rotary joint, a socket or a stand device, respectively, can incorporate such a wiring arrangement, and can use of such a wiring arrangement at a stand device, for example, in the operating room.

The present invention discloses a winding device that includes a screen, a shaft portion to which one end of the screen is fastened, a rotary shaft member that fits to an end portion of the shaft portion so that the rotary shaft member is rotated around a rotation axis along an axial direction of the shaft portion, and a biasing portion that biases the rotary shaft member in a rotation direction for winding the screen. A relative rotation restriction structure and a movement restriction structure are formed on a fitting portion between the shaft portion and the rotary shaft member. The relative rotation restriction structure restricts a relative rotation of the shaft portion with respect to the rotary shaft member. The movement restriction structure restricts a movement of the shaft portion in the axial direction with respect to the rotary shaft member.

A spool-supplying apparatus for managing a plurality of spools is presented and is comprising a spool support frame, a spool-supporting axle secured in cantilever, at a first end thereof, to the spool support frame, the spool-supporting axle being configured to support a plurality of axially-supported spools thereon, the plurality of spools axially engaging the spool-supporting axle through a second end thereof, and a spool unwinder operatively associated with the spool-supplying apparatus for unwinding a spool, the spool unwinder being configured to rotatably engage a first spool from the second end of the spool-supporting axle. A method of using the spool-supplying apparatus is also presented.

A cable system A includes a cable 3 for connecting a base device 1 and a travelling body 2, a reel device 10 mounted on the travelling body 2, a motor controller 40 for controlling a motor 15 of the reel device 10, and a rotary encoder 16 (rotation sensor) for detecting rotation of a reel 12. The motor controller 40 basically makes the motor 15 free, when the reel 12 is rotating in an unreeling direction, and basically applies a rotational torque in a reeling direction to the reel 12, when the reel 12 is rotating in the reeling direction. Furthermore, even if the reel 12 is rotating in the unreeling direction, if an unreeling speed of the cable 3 exceeds a travelling speed of the travelling body 2, the rotational torque in the reeling direction is applied to the reel 12. Slackening of the cable 3 is thereby prevented.

A method of laying an optical fiber comprises providing a continuous optical fiber, a first segment of optical-electrical hybrid cable having a first fiber receiving tube, and a second segment of optical-electrical hybrid cable having a second fiber receiving tube. The optical fiber is laid into the first fiber receiving tube using an air-blowing device. A leading end of the optical fiber is fixed in a transfer apparatus after the leading end passes through an outlet of the first fiber receiving tube. A portion of the optical fiber which has passed through the first segment is wound in the transfer apparatus until the optical fiber is completely laid in the first segment. The leading end of the optical fiber is detached from the transfer apparatus. The portion of the optical fiber which has passed through the first segment is laid into the second fiber receiving tube using the air-blowing device.

A firefighter training unit for simulating use of a fire extinguishing system, the unit including: a reel; a user-manipulable nozzle; a hose having opposite ends attached respectively to the reel and the nozzle and being partially wound around the reel, wherein rotation of the reel in a first rotational direction allows the hose to be unwound from the reel; a motor configured to drive the reel in a second rotational direction which causes the hose to be wound onto the reel; one or more devices for providing one or more output signals corresponding to one or more simulated operating conditions of the fire extinguishing system; and a controller configured to drive the motor in response to the one or more output signals so as to apply torque to the reel in the second rotational direction to simulate forces applied to the hose during operation of the fire extinguishing system.

The present invention is an apparatus, system and method for use of an offshore hose loading station comprising multiple modular reel assemblies that may be selectively configured to a frame attached to a ship and or vessel wherein the reel assemblies may be powered by one motor and engaged for rotation by one shaft and provides a jumper shaft for when a module is taken out of line.

A retractor may include various features that reduce the amount of space necessary to secure an object, for example, a wheelchair in a vehicle. In one embodiment, the webbing is designed to come off of the top of the retractor spool, which shifts the webbing take-off point from the spool rearward, as compared to prior art retractors. In another embodiment, the retractor is provided with a webbing guide that rotates around at least a portion of the circumference of the retractor spool. The rotatable guide also shifts the take-off point from the webbing guide rearward, as compared to prior art retractors. In yet another embodiment, the retractor is provided with both a rotatable webbing guide and webbing that comes off of the top of the spool.

An abseiling device includes an annular spool with an inner surface, the spool being rotatable around a central axis. The spool includes an annular gear around its periphery with gear teeth facing the central axis. A line is wound around the spool, with one end fixed to the spool and the other end having an attachment mechanism. The device also has a shaft which is co-axial with the central axis and a centrifugal brake attached to the shaft. The centrifugal brake includes brake pads for applying a breaking force to the spool. The device also has a brake gear attached to the shaft, the brake gear being rotatable with the shaft, and a compound gear. The compound gear includes a first gear for engaging with the brake gear and a second gear for engaging with the annular gear. The first gear has a greater number of teeth than the second gear. When the spool is at rest the brake pad extends around over 80% of the circumference of the inner surface of the spool.
