International Classification:

F16D 6900

US Classification:

188250G, 187370, 187375

Abstract:

An elevator safety brake for stopping an elevator car is provided with a brake shoe having a molybdenum alloy friction surface for contacting an elevator guide rail surface to provide a stopping force. The molybdenum alloy contains 99. 4 weight percent molybdenum, 0. 5 weight percent titanium and 0. 1 weight percent zirconium. The friction surface of the brake formed from the alloy exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

International Classification:

B66B 700

US Classification:

187414, 52 30

Abstract:

A hoist tool for lifting a machine assembly in an elevator to an installation position is mounted to a machine beam which also supports the machine assembly. The hoist tool is thus mounted in a location where it does not require any additional axial space. Preferably, the hoist tool is mounted to one lateral side of the machine assembly, and within an axial extension of the machine assembly downwardly from the machine beam into the hoistway.

International Classification:

A61K 3174

US Classification:

424 7808, 424426, 604 20

Abstract:

An apparatus is provided for applying to a surface of mammalian tissue including soft, living tissue an initially fluent material and then activating the material by exposure to an energy source. The material may be a liquid capable of polymerization to a non-fluent state by exposure to actinic light. The device, and methods that may be practiced in association with the device, enable a wide range of medical conditions to be treated including, for example, the application of a barrier to soft tissue to prevent post-surgical adhesions.

International Classification:

B66B 504

US Classification:

187376

Abstract:

An elevator safety brake is provided comprising two cantilevers, a pivot, a spring, and a hold-off-engagement linkage. In one embodiment, the hold-off-engagement linkage is comprised of two upper struts, and two lower struts. When it is desired to slow or stop the elevator via the safety brake, the lower struts move from a first position in which the lower struts are substantially in alignment with one another and the cantilevers are in an open position, to a second position in which the lower struts are not substantially in alignment with one another and the cantilevers are in a closed position. When the cantilevers are in the closed position, the spring exerts a force via the cantilevers on the guide rail in order to decelerate the elevator.
