  • Gear unit with improved lubricant supply
    Patent number: 9297454
    Abstract: In order to implement a reliable supply of lubricant to gear unit components during emergency or spinning operation of a gear unit, level control is provided in a lubricant sump of the gear unit as a function of the operating state by means of a control unit associated with a lubricant pump. During normal operation the level is adjusted to dry sump level. In contrast, the lubricant pump is switched off in emergency or spinning operation, so that a splash lubrication level is automatically achieved in the lubricant sump.

  • Interlacing apparatus and process for filament interlacing
    Patent number: 6112386
    Abstract: An apparatus for interlacing a multifilament yarn includes a housing with a conduit defined therethrough. A jet nozzle is configured with the housing. The jet nozzle includes a main channel symmetric to the yarn conduit axis and at least two side channels. The main channel directs a greater volume of pressurized air into a central region of the yarn conduit as compared to the side channels that direct a lesser volume of pressurized air to peripheral zones where substantially no interlacing of the yarn takes place.
