Abstract: A base for a hydraulic spreading ram for rescue work with crushed or collapsed motor vehicle bodies wherein the body must be spread to extricate a trapped victim. The base is U-shaped, having parallel upper and lower arms, and a vertical connecting arm spanning and connecting the upper and lower arms. A stationary jaw is fixed to the lower arm. A movable jaw is constrained to slide along the vertical connecting arm by guide plates fixed to the movable jaw and which ride along grooves formed in the vertical connecting arm. The upper arm is aligned with the lower arm, and has a threaded opening for receiving a correspondingly threaded hydraulic ram in an orientation such that the ram forces the movable jaw downwardly towards the stationary jaw. The movable jaw has two receptacles each disposed to receive a ram which is employed to spread the vehicle body. The two receptacles provide a selection of positions for the ram which spreads the vehicle body.

Abstract: A cable guide is provided for guiding lines or cables in a guide channel, the guide preferably having a continuous, elongated slide strip, which can be disposed in a curved orientation to form opposite upper and lower strands and a deflection zone between them. The cable guide has a plurality of guide links that can pivot relative to one another and are preferably arranged on the side of the slide strip facing away from the opposite strand and mounted on the slide strip in detachable fashion. In order to improve a generic cable guide such that it has a longer service life and less noise emission, elements are provided, in addition to any existing slide strip, that absorb the tensile forces acting in the longitudinal direction of the cable guide when it is in essentially extended position. The tensile force-absorbing elements are preferably designed as positive locking elements, e.g., in the form of projections protruding into the pivoting plane and corresponding recesses arranged on adjacent guide links.

Abstract: A method for drawing a cable which inherently lacks tensile strength into cable channels or cable pipes includes providing a tensile yarn skin on the end of the cable before the step of drawing the cable into the channels or pipes. The yarn skin can either be a net hose or a spin-wrap applied onto the cable. One application of the method is the connection of the cable incoming at a terminal tower to a switching center or exchange.

Abstract: A cable assembly includes a cable member and an outer jacket member disposed about the fiber optic cable member in slidable relation. In a preferred embodiment, the outer jacket member is a woven article, made from low friction, synthetic fibers such as polyester, nylon, Teflon, PEEK, or polyvinylidene fluoride. The outer jacket member serves as a sleeve that extends at least the same length as the cable member. In use, the outer jacket carrying the cable member may be attached at one end to a pull cord or tape that extends through the length of a conduit. A pulling force is exerted on the pull cord at a remote end of the conduit, causing the outer jacket member and cable member to be drawn through the conduit. The outer jacket bears most of the force of the pulling action, and the only force exerted directly on the fragile cable member is that of friction between the jacket and the cable.

Abstract: A platform is held atop a vertically moveable dual position leveling base by three draw screws, three push screws, and three spring-loaded pins. The leveling base is configured to secure and orient the platform such that an upper surface of the platform is substantially horizontal with allowance for adjustments in each of two positions. The platform is pushed upwardly relative to the base by the spring-loaded pins. The orientation of the platform in one position is adjusted by the three draw screws, which pull the platform down against the upward force of the spring-loaded pins. The base also has an upper position in which the platform is pressed into sealing engagement with a lower mating surface of a chamber. Three adjustable push screws provide the desired platform orientation by limiting the movement of the platform towards the base.
