Abstract: For the handling of portable large containers, lifting and depositing devices are used, which have rack and pinion jacks to be attached to the corners of the containers by brackets. There rack and pinion jacks have tubular winch shanks which are approximately the height of the containers, into which are guided tubular uprights with the racks. Because of tolerance variations, the danger here arises of an impaired guidance of the uprights with the result of a poor operation of the gearing. To avoid this difficulty, a guide tube is connected with the bottom end of each tubular winch shank. Guide surfaces in the guide tube can be produced with great precision and at low cost. The housing of the winch gearing is configured integral with the guide tube. Thus, a small amount of side play can be left between the upright and winch shank without adversely affecting the rack and pinion gearing operation.

Abstract: A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a first stop member movable along one of the X and Y axes and a clamping element a second stop member for clamping the workpiece against the first stop member for movement therewith. The second stop member element is movable independently of its associated first stop member as well as therewith, and each stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. The machine tool also includes a computer system control for operating the motors which drive the guide assemblies.

Abstract: A quick change mounting plate for securing an end fed or a side fed electrical terminal applicator, alternatively, to a press for operating the applicator, is provided with latches for locking the base plate of the respective applicator to the mounting plate. Each latch is movable between a raised latching position and a lowered position in which the latch does not interrupt the surface of the mounting plate, upon which surface the respective base plate is to be supported. The latches, one of which is positioned substantially centrally of said surface, are located to engage, in their raised positions, the edes of the base plate of the respective applicator. The latches which are not to be used for this purpose in respect of a particular base plate are kept in their lowered positions so that surface to surface contact between such base plate and the mounting plate can be achieved.

Abstract: An expansive sleeve provided with at least one stress cover associated with a hollow workpiece, which stress cover is provided with basically annular thickened regions bearing respective stress surfaces. It is desired that these outer stress surfaces be essentially in the form of cylindrical casing surfaces but that there be no radial outbowing of the individual stress surface so as to form a contact locus in the form of an arc resulting from a peak. This is achieved in that the basically annular thickened regions each comprise a protruding structure equipped with a cylindrical stress surface. With this expansive sleeve, the stress surface is no longer subject to bowing and formation of a peak contact locus comprised of an arc, because the stress surface is on the protruding structure.

Abstract: Apparatus is provided for pulling very long lengths of optical fiber and coaxial cable from a single pulling location through a polyethylene for polyvinyl chloride (PVC) subduct which extends continuously between input and output manholes through lengths of buried duct pipe and intermediate manholes. Jacketed aramid fiber pulling tape is located in the subduct with its pulling end extending out of the output end of the subduct and connected to a power driven reel. The other end of the tape extends out of the input end of the subduct and is attached to one end of the cable. Liquid silicone lubricant is poured into the input end of the subduct ahead of the cable. The power drive is energized to cause the reel to move the tape in the subduct for pulling the one end of the cable slowly into and then rapidly through the subduct with less than a prescribed maximum pulling tension on the cable. In an alternate embodiment, the lubricant is silicone grease.

Abstract: A spacer bar is used to place ceiling runners at a predetermined distance apart. At either end of the bar is pivotally mounted a holder and this allows the bar connecting together the two holders to be freely movable relative to the holders. A holder is placed on one runner in position and the second holder holds a new runner to be placed in position. The new runner may be swung in position and spaced from the first runner due to the means connecting the two runners together.

Abstract: A lifting and depositing device for portable containers comprising a plurality of rack and pinion jacks, some of which are mounted on support legs of the container. Each rack and pinion jack has an accessory gearing which can be pivoted outwardly or removed, so that when accessory gearing is pivoted outwardly, a support leg can be manually moved axially relative to its guide part, if the container, e.g., is offset on the loading surface of a truck. Thus, the gearing operation and time-consuming crank work required until now for two idle strokes per work cycle is avoided.

Abstract: In laying an electric cable underwater, the finishing end of the cable is brought ashore by laying the cable end portion (from the cable laying ship) along a course parallel to the shore and as close to the shore as the ship can reach, then pulling the cable end to shore using a rope, pulling the cable end along the shore to the intended landing point, and then pulling the cable end in-land along the intended laying line until the whole cable is positioned along this line. Buoyancy devices are attached at intervals to the cable end portion for the duration of the landing process, to facilitate the sliding movement of the cable over the bottom.

Abstract: The invention relates to a system of stretching overhead electric lines, more particularly high-tension lines, according to which a pilot cord or haulage cable is positioned in conventional manner over a set of top pulleys positioned at the highest point on each pylon in the line, and is then used to pull a first haulage cable or guard cable together with at least one other supplementary haulage cable, and/or supplementary guard cable. Each supplementary cable, after passing the top pulleys on which the first haulage cable or guard cable have been laid, is slid and guided downwards until it rests on pulleys underneath. In this manner, each further haulage cable is already positioned for drawing a conductor or bunch of conductors and other haulage cables if required.

Abstract: A surgical staple remover has two pivotally connected arms, each of which is made up of a proximal handle piece and a distal nose piece. All four pieces are held together by a single pivot pin, and the handle and nose pieces of each arm interfit with one another so that both pieces of each arm pivot as a unit about the pivot pin. The nose piece of a first arm includes two, small, laterally spaced members which can be slipped under the backspan of a surgical staple to be removed. The nose piece of the second arm includes a single member which is initially between and above the two laterally spaced members. When the arms are manually squeezed together, the single member bends the center of the staple backspan down between the laterally spaced members and pivots the legs of the staple out of the tissue.
