An elevator is provided with an auxiliary escape device consisting of a manually-operated compression-decompression apparatus located at an emergency window of the elevator cab. The compression-decompression apparatus has a fluid pipe and a compression or decompression valve which is fastened at one end thereof with an oil pressure mechanism. In the event of an accident or power outage causing the elevator to incapacitate, the compression-decompression apparatus is exerted on by the pressure of a person's hand so as to actuate the compression or decompression valve, thereby causing the oil pressure cylinder to move up or down to drive the elevator cab upwards or downwards to a desired floor where the trapped passengers can escape.       Recently Added Patents Derivative products Moving object detection using a mobile infrared camera Modified glucose dehydrogenase gene Process for formation of highly uniform arrays of nano-holes and nano-pillars Role-based access control Protecting sensitive email Method for measuring I-V characteristics of solar cell, and solar cell   Randomly Featured Patents Activity based remote control unit Flea collar concealer Method and apparatus for producing extreme ultra-violet light for use in photolithography Bed pad, an automobile seat pad, a pillow or a similar cushionlike item Drilling sampling/testing equipment Method for producing baked products Filtering unit having separately attachable filter cassette, filter cassette, and method of filtering Print data transfer system, method of transferring print data, and computer program product to effect the method Microwave oscillator having improved phase noise of oscillation signal Alkylation process of alkyl-benzene with olefin using a sodium-and-potassium catalyst © 2006-2008 PatentGenius.
