Patent number: 5407386Abstract: A fail safe, segmented drive shaft system includes a segment support assembly (16) comprising a ball bearing (26), for primary rotation, disposed within a journal bearing (28), for secondary rotation, which is disposed within an elastomeric damper (30) that has a vibration probe (34) placed in it for failure detection, and a coupling assembly (18) comprising a flexible diaphragm (66, 67) for primary, flexible coupling between segments and gear teeth (72, 73) which engage for secondary coupling upon failure of the diaphragm (66, 67). The teeth are not concentric with the rotational axis, so vibration indicates failure of the primary flexible coupling.Type: GrantFiled: February 4, 1993Date of Patent: April 18, 1995Assignee: United Technologies CorporationInventors: Jules G. Kish, Charles J. Isabelle

Patent number: 5308943Abstract: A touch button switch includes a body (10) having a conductive actuator (28) slidable from one end against a surface (62) to actuate a switch (61) on a board (52) which is held in place by hook latches (53) engaging mortises (55) in the circuit board. The surface (62) may provide conduction from the touch pad to electronic motionless switch circuitry (66) so that the touch button is usable either as a tactile switch touch button, as a motionless touch button, or both. Or, the actuator can be blocked from sliding by means of a spacer (68); and the switch (61) may be replaced by a structure (61a) holding an electrically conductive surface (62a), or not: either way, the touch button will then operate only as a motionless touch button. Or, the surface (62) can be disconnected (65) from the circuit (66), or the circuit (66) can be not installed, to operate only as a tactile switch touch button.Type: GrantFiled: December 28, 1992Date of Patent: May 3, 1994Assignee: Otis Elevator CompanyInventors: Christopher P. Screven, Bruce P. Swaybill

Patent number: 5290386Abstract: A main controller (55) causes a vision controller (36) to determine the exact location of plies (24) for a composite article in response to images from video cameras (35). The main controller then causes a robot controller (40) to direct a robot (42-46) to pick up the plies and move to a neutral position. The main controller causes the vision controller to determine that the plies were in fact picked up. If so, the main controller causes the robot controller to direct the robot to move the plies to the mold while the vision controller looks for the next ply to be picked up, in overlapped fashion. Failure to properly locate the plies and failure to verify that the plies were picked up causes an automatic retry to locate the plies or verify ply pick up.Type: GrantFiled: February 5, 1993Date of Patent: March 1, 1994Assignee: United Technologies CorporationInventor: Allen E. Trudeau

Patent number: 5271484Abstract: The present invention is directed to notifying a user of an arriving elevator car in response to a hall call registered by the user, wherein notification occurs a threshold time value before elevator car arrival. In the preferred embodiment, an elevator car is assigned to a floor in response to a hall call. The amount of time required for the assigned elevator car to arrive at the floor is determined and compared with the threshold time value. If the arrival time is greater than the threshold time value, the system reexamines assignment, possibly reassigning a different elevator car to respond to the hall call. The arrival time of the assigned (or newly assigned) elevator car is again determined, and this process continues until the arrival time is less than or equal to the threshold time value. When the arrival time is less than or equal to the threshold time value, the hall lantern at the door of the assigned elevator car is energized, e.g., illuminated and/or sounded.Type: GrantFiled: April 10, 1991Date of Patent: December 21, 1993Assignee: Otis Elevator CompanyInventors: Zuhair S. Bahjat, Joseph Bittar

Patent number: 4495431Abstract: Low reflectivity electrodes (2, 7) are provided on semiconductive and piezoelectric substrates (1, 6) including a layer (3, 9) of gold-germanium mixture and a layer (5, 8) of raw gold, or only a gold-germanium mixture (10), the total germanium content of the electrode comprising approximately 2%-3% of the total gold and germanium content of the electrode, and the thickness of the electrode being on the order of 1% of the acoustic wavelength.Type: GrantFiled: August 22, 1983Date of Patent: January 22, 1985Assignee: United Technologies CorporationInventor: Thomas W. Grudkowski

Patent number: 4321601Abstract: A terrain mapping radar utilizes two sets of separately processed radar signals, each provided by a coherent pulse doppler synthetic aperture signal processing channel connected to and for processing the signals received from a selected one of a pair of vertically displaced antennas of the type utilized in phase interferometer radars. The invention provides depression angle, and therefore elevation information from the processed signals on a cell by cell basis, uniquely, for each range/doppler cell of each of the processing channels. The invention eliminates azimuthal errors which result from the ambiguity of the range/doppler annulus, and provides a useful map metric: elevation.Type: GrantFiled: April 23, 1971Date of Patent: March 23, 1982Assignee: United Technologies CorporationInventor: Donald Richman

Patent number: 3962411Abstract: Catalytic cracking of gaseous or distillate hydrocarbon fuels for the production of hydrogen (such as for use in a fuel cell) is provided in a push/pull operated dual chamber blow and run apparatus utilizing a catalytic bed employing ring catalyzed nickel supported on porous ceramic substrates, having a graduated catalyst content such that there is a low catalyst content in the portion of the bed near the inlet and a high catalyst content in the portion of the bed near the outlet.Type: GrantFiled: May 2, 1975Date of Patent: June 8, 1976Assignee: United Technologies CorporationInventors: Herbert J. Setzer, Warren R. Standley
