Abstract: Disclosed is a hand held radius alignment tool with an adjustable pointing device, which is pivotally mounted at one end of a single u-shaped rectangular casing for finding the rotational and desired angle from 0 to 90 degrees on the radius alignment tool. The radius alignment tool is positioned on the new piece of tubing and is allowed to slide up and down and rotate around the axis of the tubing. The technician will align the pointing device's centerline to the centerline on an existing piece of tubing while sliding the radius alignment tool up and down and rotating the tool on the new tubing. Once the tubing alignment tool and its pointing device are properly aligned with the existing tubing's centerline, the technician will use the alignment-indexing marks on the tubing's grooved radius block (which is installed in the radius alignment tool) to show where to pencil mark the new tubing. The technician will mark the starting position and the orientation position on the tubing.

Abstract: Disclosed is a handcuff with a set of arcuate blades that are pivotally mounted at opposite ends of a single rectangular box-like casing. A set of telescoping handles, for slidable movement, is supported by a set of internally mounted cam assemblies. The cam assembly has concave cam surfaces. As the rectangular box-like casing bumper makes contact against the suspect's wrist, the officer will apply a forward movement of the telescoping handles. This forward movement of the handle and cam assembly causes the cam's concave surfaces to engage with the pivotal blade rollers. This will cam the blade rollers and rotates the first arcuate blade in a clockwise direction and the second blade in a counter clockwise direction encircling the suspect's wrist. To open the arcuate blades, one would insert and rotate a key to release the cam locking assembly.

Abstract: A cable gripping device which is readily adjustable and fail-safe. The device includes cylindrical inner and outer housings in telescoped relationship which contain an inner gripper member and an outer compression spring connected to the housings. When the housings are biased apart by the compression spring, the gripper member is forced into tight contact with a rope or cable passing axially through the housings, locking the assembly in position on the cable. If the housings are moved toward each other, the compression spring is compressed and the gripper member is loosened, allowing the assembly to be moved along the cable. If the operator releases the housings, such as by slipping and falling, the compression spring automatically moves the housings apart, causing the gripper to again grip the cable. This device is especially suitable for use by workers in high locations, since they can move about along a safety cable without unhooking their safety lanyards from the cable.
