Abstract: A method for effecting a repair and/or strengthening of a pipe. The method comprises cleaning an affected area of a surface of the pipe to provide a cleaned surface of the pipe surface for an area requiring repair; applying a continuous strip around the pipe from a portion prior to the effected area and allowing the continuous strip to extend to a portion after the affected area. The continuous strip forms a spiral sleeve spaced from the pipe surface to provide an annular chamber between the pipe surface and the spiral sleeve.

Abstract: A blanking line including an uncoiler, a first feeder, a slitter, and a shear. A coil of metal is carried by the uncoiler. The first feeder removes the material from the coil and typically includes a leveler for leveling the metal. The metal is fed from the leveler into a looping pit that is located between the leveler and slitter. The slitter feeds and slits the material a predetermined distance and is driven with servo motors. The looping pit acts as an accumulator allowing the metal to hang so the slitter can move metal intermittently into a shear while the leveler runs at a constant rate. The shear cuts the material to a predetermined length corresponding with the distance that the material is fed by the slitter. A measuring wheel may be included to measure the distance that the material is moved by the slitter.

An offset is added to the angle of rotation between each spacer-forming step to inhibit the nesting of bumps in the cavities of adjacent strip layers.

Abstract: A wire condenser element bending method and a wire condenser element bending apparatus bend two wire condenser elements by pressing the wire condenser elements against a bending roller to form two scroll wire condensers simultaneously. Inner edge parts of the wire condenser elements are held by holding devices at diametrically opposite positions on the outer circumference of the bending roller. Pressure rollers press the two wire condenser elements against the bending roller while the bending roller is rotated to form two scroll wire condensers simultaneously. Each wire condenser element serves as a separator for separating layers of the other wire condenser element.

Abstract: A method and an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer. Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap.

Abstract: The invention provides that a former (A,B,C) is used for forming scrolls from strip metal (30). The former has a scroll flight which is in two parts (A,B) which are relatively movable in the direction of the axis about which the former (A,B,C) rotates to coil the strip (30) about the flight (A,B) by drawing it radially into the former. In the first stage of the process the strip (30) is coiled about the inner part (A) of the flight, the outer part (B) being held displaced axially so as not to interfere with the initial coiling by the strip (30), until the strip (30) clears the end of the outer part (B) of the flight which then move into the plane of the inner part (A) of the flight and coiling can continue onto the outer part (B). The apparatus can also, in selected embodiments, include additional mechanisms for making circles and arches from the strip and for cutting, punching, twisting and right angle bending the strip from the same drive.

Abstract: This wrapping apparatus comprises a belt nester for wrapping stacks of thin amorphous steel strips about an arbor. The belt nester includes (a) a belt wrapped about the arbor and movable along its length to impart rotary motion to the arbor and (b) means for successively feeding individual ones of the stacks into the space between the belt and the arbor. The wrapping apparatus further comprises means defining a first substantially-flat surface upon which the stacks are supported as they are fed into the space between the belt and the arbor and additional means defining a second substantially-flat surface extending parallel to the first flat surface. Control means operates when a stack that is being wrapped on the arbor passes between said flat surfaces to bias one of the flat surfaces toward the other and to compress the stack between the two flat surfaces as the stack is wrapped.

Abstract: A carrier matrix wound of a carrier strip having undulations in its transverse direction has deflections of the carrier strip, said deflections being arranged in planes. During the winding process, the deflections are created by the insertion of deflection pins between the corresponding winding layers. The deflections pins, in this case, are inserted between the winding layers as a function of the desired cross-section of the carrier matrix so that after the winding process and after the removal of the deflection pins, the carrier matrix can be inserted into a sheath that has the desired cross-section of the carrier matrix. By combining several winding bodies of this type into one carrier matrix, arbitrary cross-sections of carrier matrices can be produced, particularly cross-sections having concave archings. During the making process, the deflection pins are fitted through the corresponding bores of two winding disks that are connected with one another in a torsionally fixed way.

Abstract: In this method, a plurality of elongated sheets of magentic steel are provided, and these sheets are wound in superposed relationship about an arbor, thereby forming an annulus of gradually increasing diameter about the arbor.

Abstract: A method of tensioning metallic strips on a slitting line is combined with the steps of uncoiling a metallic web having a non-uniform cross sectional thickness from an uncoiler, slitting the web into a plurality of strips having varying thicknesses, and recoiling the strips into individual strip coils on a recoiler, the tensioning method being the additional step of deforming the thinner portions of the web intermediate the uncoiling and recoiling steps so that a raised pattern is imparted to the thinner portions thereby increasing the effective cross sectional thicknesses of the thinner strips to that of the thicker strips so that the strip coils formed from the strips are of similar diameter and the strips can be recoiled at the same rate, thus preventing the formation of slack strips.

Abstract: Metallic bodies having discontinuously contacting sheet surfaces such as convolute-wound corrugated/non-corrugated metal sheet auto catalyst supports having metal-to-metal diffusion bonds formed at the contacting surfaces are provided. The diffusion bonds formed at the contacting surfaces are provided. The diffusion bonds are produced by heating the body in a non-oxidizing atmosphere, whereby metal from one surface diffuses into the metal from an adjacent surface. Some bonds may also be formed by welding. The bond-formation step may be performed in tandem with a subsequent step of oxidizing the sheet surfaces where they are not bonded, e.g. for making them into a more effectively-adhesive substrate for the catalyst they are to bear.

Abstract: A method for winding a spiral coil involving the steps of winding a metal band on a mandrel while in advance of the mandrel continuously forming a succession of regularly-spaced deformations in the band edges which protrude alternately from the opposite band surfaces to space the coil turns. During the winding, and for each successive turn, the sequence of deformations is shifted along the band, in one direction or the opposite, by a predetermined dimension such that oppositely-protruding deformations on adjacent turns come into tangential locking engagement with each other at the start of every succeeding turn and all projections on each turn come into such locking engagement. Apparatus for performing the method is also disclosed.

Abstract: A device for forming a scroll from a strip of metal, such as is used in the manufacture of wrought ironwork. An outer former with a generally cylindrical surface and a slot is rotatably mounted on a base plate and an inner former also with a substantially cylindrical surface is rotatably mounted eccentrically on the outer former. A clamping member is eccentrically arranged on the inner forming surface, so that a strip extending through the slot to lie adjacent the inner forming surface may be clamped thereto by the clamping member during relative rotation between the clamping member and the inner forming surface. Thereafter, continued rotation of the inner forming surface wraps the strip therearound while stop means prevent rotation of the outer former. The stop means is then released to allow the outer former to rotate with the inner former thereby completing the scroll by wrapping the strip around the outer forming surface.
