Abstract: A decorative ornament is supported on a Christmas tree branch by a holder comprising a pair of arms interconnected for movement between open and closed positions. A spring constantly urges the arms to the closed position in which the tree branch is affirmatively gripped by the holder, and in which the ornament is reliably locked in place on the holder.

Abstract: A life support stretcher bed includes an undercarriage which is supported on the ground for movement from one location to another by respective wheels which are commonly lockable by a braking mechanism to prevent movement of the undercarriage from a selected location. A platform is supported on the undercarriage for raising and lowering relative thereto by means of a hydraulically operating lifting arrangement which includes a control arrangement mounted on the undercarriage. An intraaortic balloon pump unit that is supported on the ground by respective casters for movement in any direction along the ground is connected to the undercarriage for shared movement therewith at a predetermined distance from the undercarriage. The platform includes straps for holding the patient supported in a supine position on the platform in such position, and side rails which can be moved from a position above the platform into an out-of-the way position.
