  • Patent number: 5627341
    Abstract: A raceway assembly is provided for repositioning an electrical fire alarm pull station from a first position to a second lower position on a wall. The assembly covers the opening in the wall at the first position so that patching of the opening at the first position is not necessary. The assembly also covers the electrical wiring which extends from the first position to the second position within the assembly, and the assembly has a low side profile to provide a pleasing appearance and minimal intrusion into the adjacent hallway or room space.

  • Patent number: 5433034
    Abstract: An ironing table (40) has an ironing board (41) which is perforated by a number of bores. A vacuum pump or suction fan is mounted in a housing (47) adjacent the board (41) and can communicate with a chamber (46) disposed below the board (41). The pump or fan operate to lower the pressure in the chamber (46) thereby forming a pressure gradient between top and bottom surfaces of the ironing board (41) whereby steam will be positively drawn from an iron through the garment being ironed, into the bores and into the chamber (46). The steam will condense on the relatively cooler walls of the chamber (46) and will drain to one end due to the inclined base of the chamber (46) and can be drained away after ironing via drainage tap.
