Patent number: 4691808Abstract: At a single floor of a building, such as at the lobby, destination calls are entered via a destination call entry device touch pad such as a (12) so that overall system response can be optimized during up-peak service intervals. A maximum number of calls are assigned to each car in order of its priority, or advantageous situation with respect to loading the lobby passengers, and the dispatch interval for each car is individually adjusted. The calls may be assigned to a car prior to its arrival at the lobby, and call assignments are audibly and/or visually displayed by an indicator device (16).Type: GrantFiled: November 17, 1986Date of Patent: September 8, 1987Assignee: Otis Elevator CompanyInventors: Frederick H.

Patent number: 4691115Abstract: A system for rotating a drive mechanism which can be connected to an electrical generator or the like. The system (10) is particularly suitable for providing electrical power to a residence and includes a reservoir (14) for containing a volume of liquid such as water (16). Weight is applied to the upper surface of the liquid for forcing it downward. This liquid is discharged from the reservoir through a spout (36) which concentrates the discharged liquid into a stream which is directed against a drive mechanism (38) such as a turbine (40) for imparting rotational forces. The discharged water is received in a catch basin (50) from which it is then moved, as by pumping, back into the reservoir for a further cycle of operation.Type: GrantFiled: January 31, 1986Date of Patent: September 1, 1987Inventor: Jerry W. Robinson

Patent number: 4685536Abstract: The respective status signals of an existing relay type elevator and an electronic elevator are loaded by a group-supervisory computer, together with hall call signals, and operation commands according to which the elevators are to respond to the hall call signals are generated and sent to the existing relay type elevator and the electronic elevator.Consequently, even in a case where one or more elevators in a relay type elevator group in operation has/have been replaced with an electronic elevator or electronic elevators, the service of elevator group supervision is prevented from lowering. Moreover, the group supervision service can be enhanced by increasing the use of an electronic elevator already and combining it with relay type elevators in operation.Type: GrantFiled: May 22, 1986Date of Patent: August 11, 1987Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Youichi Ichioka

Patent number: 4686377Abstract: A float mechanism for generating energy from waves. Floats are coupled together such that they can pivot about a horizontal axis relative to one another. Hydraulic cylinders on either side of the attachment points compress and extend with the wave motion. Check valves control flow to and from the cylinders. The floats are pivotally tied to a floating structure such that they can pivot about the structure on the surface of the water as may be required for maximum efficiency. Water compressed from the cylinders feeds a turbine which in turn feeds a generator for the generation of electrical power. In the second embodiment, floats are coupled together by means of compound bell cranks and hydraulic cylinders are coupled between alternate bell cranks at the lateral arms thereof.Type: GrantFiled: April 8, 1986Date of Patent: August 11, 1987Inventor: Gary Gargos

Patent number: 4683990Abstract: A relative position derivation, sensing and indicator system primarily adapted for conventional elevators. The system displays elevator position and travel direction at each floor with a relatively old fashioned appearing indicator apparatus including an "antique" faceplate and a simple rotatable pointer arm driven by a stepper motor assembly. Electronic solid state digital circuitry is employed to derive suitable control signals for driving the associated stepper motors which rotate the pointer arms associated with each position displayed. A plurality of vanes vertically aligned within the hoistway are provided with parallel, offset rows of perforations. A generally U-shaped vane reader traveling with the elevator car establishes a pair of rapidly pulsed, oppositely directed infrared light beams across a void-like channel formed between its sides.Type: GrantFiled: August 29, 1985Date of Patent: August 4, 1987Assignee: Innovation Industries, Inc.Inventor: Mark W.

Patent number: 4683989Abstract: An addressable elevator communication controller which, when addressed by a valid input message, prepares a return message and has its return data interface enabled for one message. The return message is automatically clocked out of the communication controller via the enabled return data interface as the next input message is clocked into the controller, regardless of whether the incoming message is addressed to this communication controller or to another communication controller. The communication controller is operable in one of two completely different modes, simply by controlling the logic level of one input pin. Input messages, as well as message clocking input pulses, are screened through digital correlators which discriminate actual signals from line noise.Type: GrantFiled: February 14, 1986Date of Patent: August 4, 1987Assignee: Westinghouse Electric Corp.Inventors: Lawrence T. Pillage, Arthur A. Anderson

Patent number: 4682673Abstract: When a plurality of preset buttons among a plurality of buttons provided on a destination call registration panel have been successively depressed in a predetermined sequence and within predetermined time intervals, the presence of a request for a special operation is determined so as to register a call to a specified floor not indicated on the panel. When the request for special operation is not determined, a call to a floor corresponding to a depressed button is registeed as usual. In this manner, the destination floor call registration panel can be used for registering cage calls under normal operation and for instructing special operation without any change.Type: GrantFiled: January 21, 1986Date of Patent: July 28, 1987Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yasukazu Umeda, Shintaro Tsuji

Patent number: 4671391Abstract: A moving distance detector for an elevator including an encoder pulse receiver having a differential amplifier for receiving input signal pulses generated upon movement of an elevator cage and transmitted on first and second signal transmission lines. Resistors are respectively connected between the first signal transmission line and a first input terminal of the differential amplifier and between the second signal transmission line and a second input terminal thereof to provide a difference between the low and high voltage signals at the first and second input terminals of the differential amplifier. Since the biasing voltage of a signal provided at one of the input terminals of the differential amplifier when the corresponding transmission line is interrupted is set to be sufficiently different from the high or low voltage level of the signal at the other input terminal, an output representing a fault or unstable state in the balancing transmission lines is readily produced.Type: GrantFiled: May 19, 1986Date of Patent: June 9, 1987Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Isao Sasao
