Abstract: Mold-free resin-insulated coil windings are obtained by applying continuous fibers embedded in a quasi-solid-state epoxy-resin matrix, e.g. in the form of a tape, to the coil windings. The tape is locally heated up to the melting point of its polymer matrix, and is subsequently pressed against the winding body. The heated and fused resin of the tape, which is pressed onto the coil, flows under pressure into the voids and gaps between the coil windings and fills them up, thereby hermetically insulating the coil windings. After leaving the heating and pressing apparatus the fused epoxy resin becomes solid again. The resulting curing process is thus considerably simplified and shortened, compared to the state of the art.

Abstract: Concentric tilted double-helix magnets, which embody a simplified design and construction method for production of magnets with very pure field content, are disclosed. The disclosed embodiment of the concentric tilted double-helix dipole magnet has the field quality required for use in accelerator beam steering applications, i.e., higher-order multipoles are reduced to a negligibly small level. Magnets with higher multipole fields can be obtained by using a simple modification of the coil winding procedure. The double-helix coil design is well-suited for winding with superconducting cable or cable-in-conduit conductors and thus is useful for applications that require fields in excess of 2 T. The coil configuration has significant advantages over conventional racetrack coils for accelerators, electrical machinery, and magneto-hydrodynamic thrusting devices.

Abstract: Methods and apparatus are provided for wire winding and fabrication for dynamo-electric machine components such as ferromagnetic armature or stator cores for motors or the like. Wire may be wound onto individual portions of dynamo-electric machine components, which may then be assembled to form complete components. Wire may be wound by steering a rotating flyer or the like in a trajectory that closely follows the surface of the core onto which the wire is being wound. Wire may also be wound by rotating the portions during winding. The same holding members that are used to hold the portions during winding may be used to hold the portions during assembly of the portions into machine components.
Abstract: A spiral wound abrasive belt is formed from an abrasive media including a plurality of webs. The webs of the abrasive media may include coated abrasives joined by splicing media or other suitable joining material. Alternatively, the webs may include individual single or multiple layers that form a coated abrasive simultaneously along with the spiral belt without the use of additional joining material. A method of forming the spiral belt includes draping the abrasive media over a fixed hub at an angle to form the spiral belt while abutting the edges of the outermost web and overlapping the outermost web and adjacent web or webs. Heat and pressure may be applied to the joined edges to form a strong bond along the spiral seam. Another method includes introducing the webs forming the abrasive media at an angle and draping the webs over a fixed hub. The abrasive media may then be passed around an adjustable hub that provides tension in the spiral belt while allowing for different circumferentially sized belts.

The scale is electrically coupled to a controller portion of the system to automatically provide the determined weight.

Abstract: A fiber optic cable is manufactured by wrapping a cable core with a corrugated steel reinforcing tape coated on each surface by a polymer material and extruding a jacket over the tape such that the polymer material on the outer surface is bonded to the jacket and the edges of the tape are overlapped and bonded. The tape is formed and spooled so as to be continuous through the spool to a required length to match the intended length of the cable which can be as much as 18 to 30 kms. The required length of the tape is obtained by slitting master rolls of steel web into individual tapes and forming welded butt splices in the steel so that each spooled tape is of the required length. A series of the spooled tapes are then unwound side by side, simultaneously laminated with two sheets of the polymer, separated each from the next and re-wound to form a spool of single tape of the required length. If the tapes are spaced side to side, the polymer material encapsulates the tape edges also.

The process provides for winding the media onto a hub and attaching a sealing element to an outer layer of the media, wherein the sealing element is attached to the outer wound layer of the pancake such that a free end of the outer wound layer of the pancake is formed in a region beneath the sealing element.
Abstract: In a method for mounting a cable winding, cable by cable, on a stator (S) for a generator a number of cables (K) of predetermined lengths are used for the intended winding. The method implies mounting each such cable starting at the stator slot representing the middle of an intended coil arc, the first cable half being mounted according to a winding diagram in one direction from the said center slot and other cable half being mounted according to the winding diagram in the opposite direction starting from the same center slot. The method is carried out by means of a device comprising a drum means, for instance in the form of a capstan machine (2), which originally supports the entire predetermined cable length of a cable. Further, there are two cable feeders (A, B) disposed on either side of the stator (S), which alternatively lay the cable (k) in the stator slots according to the winding diagram by means of intermediate storage means (3, 4).
Abstract: A device for coiling and uncoiling elongated goods (K), such as wire, cable or the like, onto a drum (13) comprises a support (12) with driving means (25) for a spreader arm (10). The spreader arm (10) is rotatably mounted on the support (12) and supports a gripping arm (14) for coiling and uncoiling the elongated goods (K) onto the stationary drum (13). The gripping arm (14) is formed as a curved V-profile having a running track arranged for the elongated goods (K), which running track is oriented towards the drum (13). The said running track is defined by feeding rollers mounted within the gripping arm (14). The feeding rollers are spherical in shape and have a rolling resistance near zero to eliminate twisting of the elongated goods (K) during coiling and uncoiling.
