Abstract: A leader member is attached at one end to a lead end of the cable on its storage reel and at its other end to a cable pulling rope. The leader member is formed from a number of flexibly connected segments. Weights are attached to the leader member to counteract the tendency of the cable to twist or rotate as it is being strung. The segments of the leader member and the weights are shaped so that they pass readily over cable stringing blocks or pulleys. The weights are located on the leader member so that only one of them at a time can be engaged and disabled by a stringing block or pulley.

Abstract: An apparatus is provided for grounding power distribution cable so that maintenance can be perfomed on power distribution equipment or the cable. The apparatus has multiple wells, at least two of which are adapted to receive any of several types of conductor bushing inserts to match the cable elbows, while a third receives a load break bushing which is adapted to receive a grounding elbow.
Abstract: An installation tool for attaching electrical lines to electrical equipment, such as at elbow to bushing terminations. The tool readily allows firm gripping and transfer of force by a servicing worker to the elbow bushing connection to insure firm connection. It is particularly adapted for use in areas too small or confined to permit use of conventional tools.
Abstract: A new and improved apparatus is provided to permit a live or hot electrical power line to be cut in the field for line service or other purposes. The apparatus is connected at each end to the line at positions spanning the site of the cut. The attached end portions are then moved closer to each other, easing the tension on the portion of the line to be cut. The apparatus is then connected to the live line with jumper cables, forming a parallel electric circuit. The line is then cut and a cut end tied back. Flow of current through the apparatus is broken. An interrupter in the apparatus suppresses any arc which may tend to form.

Abstract: A steam supply system is provided for use in conjunction with both a superposed turbine driven by a steam boiler and a process chamber. The steam boiler operates at a pressure above that needed for consumption in the process chamber and uses highly purified water. The process chamber can use steam which has been generated from relatively low purity water and may be any steam consuming process, such as in one embodiment coal gasification, not requiring that the water be returned for re-use as steam. Energy remaining in the high purity steam after it leaves the superposed turbine is used in a condensing reboiler to heat the water into steam for the process chamber. The two fluids are kept essentially isolated from contact with each other in the condensing reboiler, and the high purity water is pumped back to the high pressure boiler in a closed loop system.
