Patent number: 5052521Abstract: A stairway wheelchair lift includes a stationary motor drive unit, a rail assembly extending along the stairway and a mobile platform movable along the rail. A flexible drive member, such as a chain or cable, within the rail assembly, is driven by the motor drive unit and is connected to the mobile platform to move the platform in either direction along the rail. The mobile platform is adapted to support and transport a wheelchair-bound passenger during use, and to fold upwardly out of the way of the stairway when the lift is not in use. An automatically actuated brake mechanism stops further movement of the mobile platform when the speed of the platform relative to the rail exceeds a predetermined threshold, and a plurality of safety sensing switches prevent operation of the lift in the presence of obstructions along the stairway or other unsafe conditions.Type: GrantFiled: May 18, 1988Date of Patent: October 1, 1991Assignee: The Cheney CompanyInventors: David W.

Patent number: 4904916Abstract: A stairway wheelchair lift includes a stationary motor drive unit, a mobile platform movable along a stairway and a user interface for receiving user-generated input commands. The mobile platform communicates with the motor drive unit through a continuously maintained broadbeam infrared communications link, while the motor drive unit communicates with the mobile platform through an intermittently established short range infrared link. The user interface communicates with the motor drive through a hard wired four conductor communicates link. The use of infrared communications links, together with the four conductor hard wired link, reduces overall system wiring, enhances ease of installation and improves overall system flexibility and economy. Microprocessor based micro-controllers, within the motor drive unit, the mobile platform and the user interface, permit system operation to be tailored in accordance with the operating constraints and requirements imposed by a particular stairway configuration.Type: GrantFiled: May 18, 1988Date of Patent: February 27, 1990Assignee: The Cheney CompanyInventors: Edward T. Gisske, John F. Prendergast, Sr.

Patent number: 4568864Abstract: A solid-state electronic control system for an electric motor which drives a pipe bending machine. A machine operator's hand switch acts through a logic system to cause the motor to run in either direction, and negates control conflicts.The logic system controls an SCR bridge system to select the direction of D.C. energization of the motor for forward or reverse drive. This bridge system is supplied from A.C. mains through a bridge rectifier comprising three diodes and one SCR. When motor drive is called for, this SCR is made conducting to provide full-wave rectification. When motor drive is terminated, this SCR is turned off so that the rectifier becomes half-wave, which facilitates turn-off of the motor reversing SCR's.A dynamic brake for the motor is turned on by a triac when motor energization is shut off.Type: GrantFiled: August 6, 1984Date of Patent: February 4, 1986Assignee: Ex-Cell-O CorporationInventor: Edward T.

Patent number: 4245148Abstract: A control circuit is disclosed suitable for use with a toaster or other food browning device which utilizes a radiant energy source to brown food. A light sensitive variable resistor, or photocell, is optically coupled to light reflected from the food being browned in the device. A voltage generated by a voltage divider including the light sensitive resistor therein is compared with a preselectable voltage generated by a second voltage divider to determine whether the heat source should be turned on or off. Suitable solid state control circuitry is provided to ensure that a start-up delay is provided at the beginning of each browning cycle and to reset the circuit for future operation when the desired browning of the food is achieved.Type: GrantFiled: September 14, 1979Date of Patent: January 13, 1981Assignee: Wisco Industries, Inc.Inventors: Edward T.
