Appl. No.:

09/824419

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02K 112

US Classification:

602263, 60232, 244219

Abstract:

A gas turbine engine includes a variable area nozzle having a plurality of flaps. The flaps are actuated by a plurality of actuating mechanisms driven by shape memory alloy (SMA) actuators to vary fan exist nozzle area. The SMA actuator has a deformed shape in its martensitic state and a parent shape in its austenitic state. The SMA actuator is heated to transform from martensitic state to austenitic state generating a force output to actuate the flaps. The variable area nozzle also includes a plurality of return mechanisms deforming the SMA actuator when the SMA actuator is in its martensitic state.

Appl. No.:

11/815694

Inventors:

Boris Traktovenko - Avon CT, US
Robin Mihekun Miller - Canton CT, US

Assignee:

Otis Elevator Company - Farmington CT

International Classification:

B66B 1/34

US Classification:

187391, 187277, 187289

Abstract:

An elevator machine () assembly useful in an elevator system () includes a motor frame () that supports a motor () for selectively rotating a motor shaft (). A brake () selectively applies a braking force to resist rotation of the motor shaft (). At least one load sensor () resists undesirable movement of the brake () and provides an indication of a load that results from applying the braking force. A disclosed example includes using a first resistive member () to resist movement of the brake () relative to the motor frame () when the load is below a threshold load and using a second resistive member () to resist movement when the load exceeds the threshold load.

International Classification:

F01B029/10
F02G001/04

US Classification:

060527000

Abstract:

A plurality of individual shape memory alloy (SMA) wires are formed into a SMA bundle to increase force output therefrom. The SMA bundle has a parent shape and a deformed shape. The SMA bundle in the deformed shape resumes its parent shape once the SMA bundle is heated to generate increased force output. The SMA wires can be configured into strands, ropes, arrays or other shapes. The SMA material is also used in a variety of actuators for generating substantially continuous motion.

International Classification:

F16H057/08

US Classification:

074462000

Abstract:

A transmission provides for the application of higher design allowables in bending, pitting, and scoring, as enabled by surface-engineering (SE) processes such as isotropic superfinishing and Me-DLC coating to effect increases in the power density of transmission systems.

US Classification:

310092000, 310112000, 310156020

Abstract:

An elevator machine () has a plurality of identical transverse flux rotor/stator modules (-) of a generally cylindrical configuration arranged contiguously on a common shaft () to provide torque to the shaft equal to the torque capability of the modules times the number of modules. A disc brake () is integrated with the motor; a two-sided brake disc () has friction pads () on both sides, braking force being applied to motor end plate () and through the brake disc to a stator () of one phase () of the motor. A process () forms variously-sized motors from identically sized modular components, in various configurations ().

International Classification:

B66B 7/10

US Classification:

187412

Abstract:

An elevator system () load bearing assembly () includes a plurality of load bearing members (-). At least one of the load bearing members (-) has a load carrying capacity that is different than at least one other of the load bearing members (-). A disclosed example includes equal numbers of load bearing members () having a first load carrying capacity and equal numbers of load bearing members () having a second, different load carrying capacities. Another example includes at least three different load carrying capacities. With the disclosed examples, the aggregate load carrying capacity of an elevator load bearing assembly () can more closely meet the load carrying requirements for a given elevator system without over-roping the system.
