  • Publication number: 20080093908
    Abstract: A moveable armrest is provided that pivots from a standard use position to a stowed position behind the backrest of a vehicle seat. The armrest pivots about a horizontal axis for movement from a horizontal position along the side of the seat to a vertical position along the side of the seat, and pivots about a vertical axis for movement from the vertical position adjacent to the inboard side of the seat to a vertical position behind the backrest of the seat. The moveable armrest includes a locking mechanism to prevent unintentional movement of the armrest.

  • Patent number: 6444961
    Abstract: Temperature self-regulating food delivery systems are provided having a magnetic induction heater (32, 126) and an associated food container (76, 124) equipped with an essentially permanent ferromagnetic heating element (82, 100, 128). The heater (32, 126) and heating elements (82, 100, 128) are designed so as to heat the element (82, 100, 128) to a user-selected regulation temperature when the elements (82, 100, 128) are coupled with the heater's magnetic field, and to maintain the temperature in the vicinity of the regulation temperature indefinitely temperature regulation is a heating achieved by periodically determining at least two parameters of the heaters resonant circuits related to the amplitude of the resonant current passing therethrough during heating and responsively altering the field strength of the magnetic field. Preferably, the value of the resonant circuit amplitude and the rate of change of the amplitude are determine.

  • Patent number: 5826393
    Abstract: An adjustable, fastenerless modular shutter includes end rails having an end wall and a pair of locking portions extending therefrom. The locking portions are slidably receivable in a pair of side rails and engage the side rails to resist separation of the end rails from the side rails during assembly of the shutter. An adjusting member located on the end rail permits adjustable engagement of a shutter panel to the end rail to permit positioning and retention of the shutter panel relative to one of the end rails.

  • Patent number: 5295633
    Abstract: A paper shredder with a cutting mechanism and strippers that are formed on the bottom base of the shredder. The strippers have an arcuate shaped portion to substantially surround the space between adjacent cutting disks to prevent shredded paper from accumulating and clogging the cutting mechanism. The paper shredder has cutting disks with teeth that include a piercing tooth and a flat tooth.
