  • LED lighting element
    Patent number: 9091422
    Abstract: An LED lighting element having an H-shaped housing. The housing, which may be an extruded housing, has a first section and a second section which is separated from the first section by a cross bar. A back plate is positioned opposite of the crossbar and is removably secured to the first section. A heat sink is located within the housing while a microcontroller and LED drive/control technology and integrated power supply contacts the heat sink and is attached to the back plate. An LED PC board that is electrically connected to the microcontroller and LED drive/control technology and integrated power supply is positioned in the second section and is attached to the housing. An end cap for the housing along with a method for constructing the lighting element are also disclosed.

  • Linear motion bearing assembly with integral performance enhancing features
    Patent number: 6435718
    Abstract: A self-lubricating bearing assembly for supporting a load on a guide rail which includes a carriage having first and second ends, a guide surface adapter for translation atop the guide rail and an end cap assembly which mounts adjacent one of the ends of the carriage. The end cap assembly includes a seal and a lubricating assembly having a lubricating block made from a lubricant composition and a compression housing for enclosing a periphery of the lubricating block and for biasing the lubricating block against the guide rail to cause the lubricant to contact the rail.
