  • Patent number: 7240582
    Abstract: An override device is proposed to permit the manual operation of a closure which is normally driven by an electric motor. The override device comprises a manual closure driving mechanism, such as a chain engaged around a pulley, which when operated first produces the translation of a first gear along its rotation axis until this first gear meshes with a second gear connected to the output shaft of the motor which normally drives the closure. During the translation of the first gear, a switch is tripped to safely interrupt power to the motor and a mechanism is operated to disengage the motor from the output shaft. Thereafter, further operation of the chain, and therefore further rotation of the pulley, is adapted to cause the first gear to rotate instead of translating, whereby the second gear is driven into rotation by the first gear thereby causing the rotation of the output shaft and the manual operation of the closure.

  • Patent number: 6520987
    Abstract: An intravascular flexible permanent prosthesis (stent) for implantation in a body lumen such as an artery, consists of a plurality of radially expandable and deformable thin-walled ring elements aligned in a common longitudinal axis, and held together by interconnecting links so as to limit longitudinal expansion or contraction during radial deployment. The stent is delivered and expanded within a blood vessel by an angioplasty balloon catheter. The ring elements are formed of a series of hexagonal components or inverted hexagonal components, with elements of a series of hexagonal components preferably alternating with elements formed of a series of inverted hexagonal components. Each point of adjacent ring elements is adjoined by a pair of diametrically opposed links, whilst the succeeding pair of adjacent ring elements is adjoined by a pair of links which are diametrically opposed and located at an angle of 90° to the previous pair of links.

  • Patent number: 6449967
    Abstract: A high-speed evaporator defrost system is described. It comprises a defrost conduit circuit having valves for directing hot high pressure refrigerant gas from a discharge line of a compressor and through a refrigeration coil of an evaporator of a refrigeration system during a defrost cycle thereof, and back to a suction header of the compressor through a reservoir of the refrigeration system to remove any liquid refrigerant contained in the refrigerant gas prior to returning to the suction header. The reservoir has an internal pressure which is generally at the same pressure as that of a suction header of the compressor thereby creating a pressure differential across the refrigeration coil sufficient to accelerate the hot high pressure refrigerant gas in the discharge line through the refrigeration coil of the evaporator to quickly defrost the refrigeration coil. The reservoir is repressurized after the defrost cycle for using the reservoir in a refrigeration cycle.
