摘要： A hydraulic unit has a hydraulic component, a hydraulic line connected to a hydraulic connection of the hydraulic component, and a hose and fitting connected to the hydraulic connection. A tear-out preventer having a cable loop secured by a cable clamp acts on the hose. The cable clamp comprises a clamping block, which has two crossing passages and a rivet. A first passage, through which the cable is guided, has, in the region of the crossing with the second passage, a width corresponding to at least double the thickness of the cable plus the diameter of the non-deformed rivet. The second passage is configured in a stepped manner with a narrow primary portion arranged on one side of the first passage and a wide secondary portion arranged on the other side. The rivet braces the two strands of the cable against the inner wall of the first passage.

摘要： A through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is provided. The apparatus includes a web-carrying structure configured to move and a first component having at least one sealing element adjacent the web-carrying structure, where the sealing element is configured to reduce the infiltration of ambient air into the through-air apparatus. The apparatus also includes at least one channel configured to direct air to the sealing element to reduce the infiltration of ambient air into the through-air apparatus. A method of operating a through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is also provided. The method includes directing air to a sealing element to reduce the infiltration of ambient air into the through-air apparatus.

摘要： A thread protector that has an external sleeve to protect threads disposed on a tubular member. The thread protector includes a flange disposed on a first end of the external sleeve to be engageable with an end of the tubular member. The thread protector also includes a securing apparatus extending from the flange to frictionally engage an inner side of the tubular member to maintain the thread protector's engagement with the tubular member, the securing apparatus including a magnet that increases the force of the frictional engagement of the securing apparatus with the inner side of the tubular member. The securing apparatus can also extend from the flange to frictionally engage an inner side of the tubular member to maintain the thread protector's engagement with the tubular member, the securing apparatus rotatable relative to the external sleeve. A method of protecting pin threads of pin ends of tubular members by installing a thread protector on an end of a tubular member.

摘要： A temporary pipeline protection apparatus. The apparatus includes a cylindrical sleeve having a pair of halves, each of the halves having a pair of opposed edges parallel to an axis of the cylindrical sleeve. A first edge of each pair of edges of the halves are connected together by at least one hinge assembly configured to move among a closed position, an installation and removal position, and a shipping and transportation position. A latch is configured to close the cylindrical sleeve at a second edge of each of the edges when in the closed position.

摘要： A long object guiding device includes a long tubular member and is configured to guide a long object inserted through the tubular member while protecting, with the tubular member, the long object in correspondence with displacement of the tubular member. The tubular member has a long sheet shape in an unfolded state. A longitudinal direction of the tubular member intersects a width direction. A first joint portion is disposed on one side edge of the tubular member in the width direction to extend in the longitudinal direction. A second joint portion is disposed on an other side edge of the tubular member in the width direction to extend in the longitudinal direction. At least one end of the tubular member, in the longitudinal direction, has a passage portion that allows for passage of an end of the long object.
