A conduit system for laying cables along the floor of a passenger cabin of an aircraft includes longitudinal and transverse cable guide elements respectively forming cable channels, and cable branch junctions at intersections of the longitudinal and transverse guide elements. Each guide element includes a lower part secured to the cabin floor, and an upper part secured (e.g. snap fitted) onto the lower part to cover the cable channel. The cable branch junction includes a lower section secured to the floor and covered by an upper section, and allows the cables to continue straight through the junction or to be deflected by 90° or by 180°. With this arrangement, a greater number and greater diameter of cables can be laid out with a minimal installation effort. The components of the system are easily adaptable to any required installation layout, while providing a continuous covered protected enclosure for the cables.

A shock absorber that combines both the suspension function and the shock absorbing function in one unit. It has an elongated shock body filled with hydraulic fluid and a piston mounted on a piston rod that reciprocally travels within the shock body. The shock body is telescopically received in a bypass cylinder body having a greater diameter that produces an annular chamber between the outer surface of the shock body and the inner surface of the bypass cylinder body. A coil spring is mounted on the outside surface of the bypass cylinder body to provide a suspension function by the shock absorber. A plurality of bypass tubes are associated with longitudinally spaced ports in the shock body. Adjuster rods are telescopically received inside the respective bypass tubes for controlling whether the individual ports are closed, partially open, or fully open. These adjuster rods would be manipulated externally of the shock absorber assembly.

A tungsten steel cutter which is lower cost to use and can increase fabrication efficiency and improve quality mainly includes a shank and a bit screwing at a front end of the shank. Both are made of tungsten steel and formed in an integrated fashion. The shank has a screw hole at the front end and a coupling trough formed at the front end of the screw hole. The bit has a screw bar extended from the bottom end thereof and a coupling neck at the front section of the screw bar. The coupling trough is formed at a depth same as the height of the coupling neck and the coupling trough and the coupling neck are formed at the same size. The bit and the shank have respectively a water discharge passage and a water drawing passage, and a water intake passage that communicate with each other. The water intake passage is formed at a greater diameter than the water discharge passage and water drawing passage. Thus when the bit and the shank are screwed together, in addition to screw coupling of the screw hole and the screw bar, the coupling trough and the coupling neck also form a tight coupling to minimize gaps that might otherwise happen between them like the conventional ones do. The water discharge passage and water intake passage provide cooling effect for cutting fluid and prevent debris from accumulating on the bit and affecting cutting quality. The invention provides a two-section coupling that can save the cost and improve steadiness and fabrication efficiency of precision tools.
