US Patent:

44492626, May 22, 1984

Filed:

Sep 8, 1981

Appl. No.:

6/299881

Inventors:

Hendrick Jahsman - Berkeley CA
George Menor - Martinez CA

Assignee:

Siemens Medical Laboratories, Inc. - Walnut Creek CA

International Classification:

A61G 700

US Classification:

5 63

Abstract:

The medical couch contains a lower frame, an upper frame for carrying a patient table top, and a link mechanism interconnecting both frames. The link mechanism includes two pairs of pivotally interconnected support arms which are operated in a scissors action to lift and lower the upper frame with respect to the lower frame. An electronic motor drive system containing an electric motor and a lead screw is provided for performing such operation. The drive system is pivotally connected to the lower frame such that the lead screw extends towards the upper frame. The drive system is rotatable about a pivoting axis which is arranged horizontally. A nut element which is mounted on the lead screw travels therealong when the motor is in operation. The nut element is provided for supporting the link mechanism. It is pivotally connected therewith.

The nut element will be pivoted about an upper horizontal axis when it travels along the lead screw. The nut element moves the upper frame to a selected horizontal position above and parallel to the lower frame.

International Classification:

US Classification:

244121

Abstract:

An aircraft canopy fracturing system includes a canopy having fore and aft portions and a region that is severable from the canopy to provide an opening therethrough for the egress of aircraft occupants. The severable region has a shape that inhibits passage of the severable region through the opening created in the canopy once the severable region is freed from the canopy and is displaced aftward relative to the canopy. The canopy fracturing system also may include one or more mechanisms that will impart an aftward impulse to the severable region of the canopy once it has been severed and freed from the remainder of the canopy.
