  • Patent number: 4989402
    Abstract: The invention relates to textile machine control. The run of spinning units is controlled by two busses, a two-way bus, and a reserve one-way bus, the latter being activated, as a rule, by a central electronic system, and possibly, though less often, by the operator. A suitable arrangement of the circuits on the criterion of whether they belong to the two-way bus or to the one-way one, facilitates troubleshooting and permits shorter repair time on vast systems comprising a plurality of work stations of the textile machine.The invention can be used on various types of spinning machines where a predetermined length of wound yarn is required.

  • Patent number: 4974791
    Abstract: A magnetic tape cassette has an improved reel spring, slack limiter and tape guide. The reel spring has a generally rectangular shape with first and second parallel edges extending substantially along its entire length. A flat, central base portion of the spring is bounded by a pair of transition portions which extend at an angle out of the plane of the base. A pair of outer end portions set at a sharper angle to the base complete the spring configuration. A polypropylene slack limiter applies a preloaded tension on the magnetic tape. The polypropylene eliminates the need for laminating a separate bearing material to the slack limiter. The tape guide has a semi-cylindrical, stainless steel insert attached to a plastic mounting core. The core is fastened to the cassette housing.

  • Patent number: 4958404
    Abstract: A card for producing fibrous webs or random webs of textile fibers comprises a plurality of cylinders in series with metallic wire. The cylinders rotate in a predetermined mutual sense to which worker rolls are coordinated. The cylinders and workers are covered by trough-shaped plates. The trough-shaped cover of the cylinders or workers (7, 8, 9) is formed of a plurality of trough sections (20a, 20b, 20c, 20d, 20e) which are arranged in close succession. The trough sections are adapted to be adjustable and to be opened respectively. By this means, a control of the optimum air amount at the rollers may be achieved uniformly over the working width.

  • Patent number: 4936028
    Abstract: A shoe with replaceable outsole, destined for use as a tourist, army, work, etc. shoe. It is basically comprised of an upper portion (the shoe itself) to which the uppersole is permanently attached in some manner, a removable outsole with an interlocking feature on top which engages with the bottom of the uppersole and with a varying bottom portion (depending on the use it is put to) and, a removable set of connector rods.The uppersole on it's bottom portion has a tread with a set of openings. On the upper portion of the outsole there is a tread with a similar set of openings, fitting exactly into the space between the openings of the uppersole. The two interlock to form a complete sole. Horizontal openings or bushings are placed in straight lines the length of the sole. Removable connector rods are then placed into these openings or bushings, providing a secure attachment for the outsole.

  • Patent number: 4936030
    Abstract: This invention relates to a shoe having a mechanism in its sole to transmit the mechanical energy of heel impact to the front of the foot, where it is stored and then released during thrust. The mechanical energy of the impact on the rest of the foot (in front of the heel) is also stored and then released during thrust. The shoe is energy-efficient in that it returns as much of the energy of impact as possible to the runner during thrust. This means that the leg and foot muscles do not have to do as much work to lift the body weight against gravity. In addition to this resiliency feature, there is a compliance feature which reduces the impact shock on the runner's skeleton, muscles, and tendons. This compliance is achieved because the foot impact force is transmitted to the upper skeleton through a spring, which softens the shock transmitted to this upper skeleton.

  • Patent number: 4936521
    Abstract: In a winding machine where material is wound onto a non-rotating spool by a flyer that revolves around the spool, a device for moving, clamping, and releasing the spool moves the spool into position for winding, traverses the spool axially as the flyer rotates around the spool to properly distribute the material on the spool, and moves the spool away from the winding position. The device also clamps the spool as it moves the spool into position for winding and unclamps the spool as it moves the spool away from the winding position.

  • Patent number: 4934620
    Abstract: For the construction of an insulating wound body 8 for electrical insulation purposes, in an installation 50 for the formation of a stack 24, sheets 21 and/or precut sheets blanks 21' are prepared from a web of material. The sheet stack 24 precedes the winding apparatus 10 and the winding material is supplied in a manner such that the width of the sheets corresponding to the winding width coincides with the length of the sheet segment, and the length of the sheets corresponds to the width of the web. The winding material is taken by a perforated conveyor 9 revolving around rolls (in the running direction of the winding apparatus 10), and the insulating sheets 21 and/or sheet blanks 21' are entrained by the segment of the conveyor belt between a lower roll 1 and the preceding reversing roll 3 and wound with edge to edge contact, without gaps, onto a conductor or inner tube 5 freely supported between the stationary lower roll 1 and upwardly mobile upper roll 2, without tensile stresses.

  • Patent number: 4930711
    Abstract: A method and apparatus for removing a section of a sheet of material being wound on a roll. The apparatus removes the section and then positions the lengths preceding and following the removed section in overlapping relationship with one another so that the overlapped lengths can be wound onto the roll. In the preferred embodiment, the preceding length of the sheet is temporarily displaced from the travel path by a vacuum plate and, during the temporary displacement, the section to be removed is moved downstream to a discharge position and the following length is moved into overlapping relationship with the displaced preceding length. Additional winding assemblies for winding the sheet onto other rolls can be used to provide a substantially continuous winding operation.

  • Patent number: 4928904
    Abstract: A position sensor for sensing the position of an optical fiber with respect to the axis of a bobbin as the fiber is being wound to the bobbin. The apparatus and method illuminate the fiber being fed onto a bobbin with an externally incident energy which is internally reflected within a portion of the fiber. The position of the illuminated portion of the fiber is detected and the winding process may be controlled based on the detected position.

  • Patent number: 4923140
    Abstract: A bail reversing apparatus of the invention has an abutting member formed on the reel body which is made to abut against a kick member to turn the kick member and thereby return the bail support member to the reel-up position. This enables efficient, quick and smooth reversing of the bail support member and does not require high precision in machining the kick member. The apparatus is also characterized in that the kick member is, either directly or through a working rod, connected to the bail support member, so that the reversing mechanism becomes very simple contributing to further reductions in the weight and size of the rotor.

  • Patent number: 4921184
    Abstract: A locking mechanism for looking a winding shaft wound a webbing to prevent the winding shaft from rotating at excessive movement more than a predetermined amount of acceleration in a horizontal direction. The locking mechanism has an operating member which is inclined at the excessive movement more than the predetermined amount of acceleration in the horizontal direction to lock the winding shaft. The operating body has a pair of plate-like inertia portions extended symmetrically with respect to the axis of the winding shaft in the direction to approach an outer periphery of the webbing wound around the winding shaft. The operating body is inclined by the inertia portions when the acceleration is exerted. Thus, the locking mechanism locks the winding shaft by means of these inertia portions and the locking mechanism can be made small in the vertical direction.
