  • Patent number: 5536097
    Abstract: A modular system uses a plurality of metal pipes each having an orthogonal array of coplanar openings at one end and a threaded bore at the other end. An insert is inserted in a first pipe bore at one end next to the openings, the insert having a set of like threaded bores aligned with the openings. A coupling member external the pipe is aligned with each opening and has a bore aligned with these openings. A plurality of bolts each with a threaded end is attached to a different threaded insert bore through a coupling member and pipe opening. The bolts each have an annular groove which is aligned with a threaded bore at a second pipe other end. A set screw in the second pipe threaded bore secures the bolt by engaging the groove, locking the second pipe to the first. A foot is threaded to a lowermost vertical pipe and an end cap is used as insert for the uppermost vertical pipe.

  • Patent number: 5524834
    Abstract: The arrangement controls thread tension in a spool creel with a brake rotor (brake drum 4) for each spool holder (1). A braking element (brake band 5) operates therewith and is biasable by a tensioning lever (8) which takes an angular setting dependent upon the thread tension and the force of gravity. A fluid pressure activated biasing arrangement 13 influences the tensioning lever 8 at each spool holder 1. The fluid pressure is commonly adjustable for all of the biasing arrangements 13. In this manner a general changing of the thread tension can be combined with control of individual thread tension.

  • Patent number: 5523414
    Abstract: In the production of an N-unsubstituted maleinimide by the ring-closing alcohol-removing treatment of an N-unsubstituted maleinamic ester for conversion into an imide, an acid catalyst or a mono(cyclo)alkyl sulfuric ester is used for the reaction. In this case, the alcohol concentration in the reaction solution is preferable to be adjusted to a low level. By using a maleinamic acid and an alcohol in conjunction with an inert solvent and an acid catalyst, a mixture of maleinamic acid with an acid catalyst, or a mono(cyclo)alkyl sulfuric ester, a corresponding maleinamic ester is obtained.

  • Patent number: 5520023
    Abstract: A warp knitting machine has a machine base (10), a main shaft (12) and knitting tool bars (13 to 17). Placed on the machine base is at least one gear box (18), having at least one side wall (24, 41), which is pierced by a bearing (25). A gear mechanism (27; 43) interacts on an inner portion of a shaft segment (24; 41). The outer portion of this shaft segment is drivably connected with a carrier arm (19; 37) for tool bars (13, 14, 15). In this manner, one obtains a very compact construction which inhibits oil leakage and substantially reduces noise emission while also offering the possibility of reducing the force necessary to operate the bars.

  • Patent number: 5491996
    Abstract: A stabilizer bar or a similar metallic tube product for vehicles, has a central portion and at least two bent portions forming legs. The bar includes a thick-walled metallic tube having in the central portion a wall thickness and outside diameter in a ratio amounting to at least 1/10. This tube has an outside wall portion bent with a restricted thinning, ranging from about 5 to 15%. The bent portions are bent with an average bending radius of curvature in the range from about 1.4 to 2.1 times the outside diameter of the tube. Apparatus and methods can manufacture stabilizer bars or similar tubular metallic products of the foregoing type. For example, a method includes the steps of fitting to a bending arm one end of the thick-walled metallic tube. An inside wall portion of the tube has a radial spacing from a bending center of curvature, no greater than the length of the bending arm. The tube and the heating zone move relatively, with the heating zone advancing along the tube.

  • Patent number: 5461881
    Abstract: An arrangement for driving a warp beam employs a stepless adjustable drive (7) whose coupling element (8) is displaced by a setting member (11). The setting member (11) is controlled-by a computer (10) which provides an input arrangement (17) for the take-up of data of a predetermined thread provision (F); as well as data on the machine, the stepless adjustable drive (7) and the beam (3). The data includes a wind variable size (actual wind number w.sub.a), and data characterizing the actual wind circumference (U.sub.a). The computer has a calculating segment (18) and an output (19). With such an arrangement, the coupling element (8) can be brought into the correct target position, even before the start of the machine. The computing means can also serve as part of the control arrangement during the running of the machine.
