  • Method and equipment for Jacquard selection in a textile machine
    Patent number: 6145349
    Abstract: The invention relates to Jacquard selection in a textile machine characterized by a selection jack (1) provided with a spring (M1) by which, after the preselection phase in which the jacks are guided by a cam inside the cylinder, they move out under the pressure of the spring, thus modifying the path or the functions; or remain contained and/or retained in the cylinder by a selector and/or other member disposed frontally which prevents their moving out. According to circumstances, the selector, even if fixed, can move vertically, horizontally and also radially, with minimum time and space, without lateral impact on the incoming butts and/or jacks. Finally, the actuators, together with the cams of the jacks and/or needles, are incorporated in a modular support to modify the type of selection and/or for textile operations other than the Jacquard type.

  • Method and apparatus for bandwidth control in an over subscribed computer network switch
    Patent number: 6145010
    Abstract: A switch of a computer network with a plurality of dual speed Ethernet client ports and at least one high speed Ethernet uplink port. The combined data rate of the Ethernet dual speed client ports has a maximum value which is higher than the data rate of the Ethernet uplink port. The Bandwidth Control limits the number of enabled Ethernet client ports so that the combined data rate of the enabled client ports substantially equals, or slights exceeds the data rate of the uplink port. In this way the speed and amount of switch memory can be minimized in the switch itself and the memory burden is divided among the clients. The dividing of the memory burden greatly reduces the worst case scenario and allows each client to individually chose the speed and amount of memory based on its own cost/benefit situation.
