Abstract: A method for producing an electrocompacted and aligned strand is disclosed. The method includes the steps of: providing a channel having an anode on one side and a cathode on the other side separated by a non-conductive material to form an electrode; dispensing a solution comprising one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature into the channel to complete a circuit between the anode and the cathode; applying a DC current in the range of 1-200 volts to the electrode through the solution in the channel to form an electrocompacted and aligned strand; and transferring the aligned strand out of the electrode. The one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature can comprise collagen molecules that have different charges at different pH values. Materials including electrochemically aligned and compacted compounds are also disclosed.

Abstract: The present application discloses a magnetic component, comprising a magnetic core comprising at least one core column; a winding winded on the core column and comprising a first coil and a second coil adjacent to the first coil; a cladding member covered on at least a portion of an external surface of the first coil; and a positioning member extending from the cladding member and the first coil, wherein the second coil is pressed on the positioning member.

Abstract: Apparatus and method for use in handling a load, the apparatus comprising a load bearing elongate member (2) and a load bearing mechanism for paying out and recovering the load bearing elongate member; at least one service umbilical (9, 10) and a mechanism (12) for paying out and recovering the service umbilical; at least one securing member, and a wrapping device (15, 16) for rotating the securing member around the load bearing elongate member and the service umbilical as they are being paid out and to unwrap the or each securing member from the load bearing elongate member and the service umbilical as they are recovered. The rotation of the securing member by the wrapping device is powered by power supplied via a power conduit (25) in the form of an elongate flexible conduit wrapped onto a power conduit drum that has a central axial bore arranged concentrically with the load bearing elongate member during handling of the load.

Abstract: A filament winding device enables fiber bundles to be wound around the outer circumference surface of a liner at equal intervals even when the winding angle of the fiber bundles changes. The filament winding device includes a first helical head on which fiber bundle guides are radially disposed in the periphery of a liner to be transported; and a second helical head which is disposed adjacent to the first helical head and on which the fiber bundle guides are radially disposed in the periphery of the liner The filament winding device also has phase adjusting means for adjusting the phase difference between the fiber bundle guides on the first helical head and and on the second helical head in accordance with the angle (?) at which the fiber bundle is wound around the liner.

Abstract: A filament winding apparatus that prevents excessive unraveling of a fiber bundle due to variations in the speed at which the fiber bundle is wound includes a hoop winding device having a wrapping table, a bobbin support unit, a braking unit, a slack removal unit, a detector, and a controller. The slack removal unit absorbs slack caused by the difference between winding and unraveling speeds of the fiber bundle. The detector detects whether the amount of slack absorbed is equal to or greater than or is less than, a predetermined amount. When the amount of slack is equal to or greater than the predetermined amount, the controller increases the braking force of the braking unit for braking rotation of a bobbin. When the amount of slack is less than the predetermined amount, the controller reduces the braking force of the braking unit for braking rotation of the bobbin.

Abstract: Disclosed is a filament winding device wherein an FRP layer is prevented from becoming thick by avoiding piled fibers in the case of the feeding of multiple filaments when a plurality of fibers are fed simultaneously. For realizing this theme, a filament winding device moves a fiber guide member equipped with a plurality of fiber feeding ports relatively in an axial direction of a wound member rotating relatively about the axis, and feeds fibers through the fiber feeding ports to wind the fibers around the wound member, wherein the fiber feeding ports are provided only in part of the fiber guide member. When the fiber guide member is moved relatively in the axial direction of the wound member, a plurality of fibers are fed only from one side when viewed from the wound member and the fibers are wound around the wound member while being gathered on the periphery of the wound member.

Abstract: A winding apparatus for and a method of applying a winding of a band-like material to a limb of a transformer core. The winding apparatus includes a guide member arranged to be fixed in relation to the core limb and a rotary member carrying a supply of a band-like material.

Abstract: A filament winding apparatus reduces fluctuations in a winding operation by bringing a plurality of guide portions that guide fiber bundles to a liner close to the liner in a winding unit. Each of the guide portions is a tubular member having a guide hole penetrated from a base end to a leading end portion. The leading end portion has a smaller thickness width. Each of the guide portions guides a second fiber bundle to the liner by passing the second fiber bundle from a side of the base end portion to a side of the leading end portion of the guide hole. By rotating each of the guide portions about an axis of the guide portion, and by sliding the guide portions in the radius direction of the liner, the guide portions can be brought close to the liner.

Abstract: A continuous winding machine uses embedded controllers to monitor and control the winding settings in maximum speed applications. Power is supplied to the embedded controllers from a main power source through a rotary transformer. The control system can be operated either through wired connections to a local computer or processor, or through a wireless system, or a combination of both, depending on the specific application. The machine uses a high speed, closed loop tensioning system that includes the filament supply spools and the mandrel supply and takeup spools. The control system menu includes the various winding operations useful to each user. The control system menu can be accessed remotely via computer, or by telephone.
