Abstract: A ram feed waste incinerator apparatus includes a vertical waste storage cylinder positioned above a combustion chamber and contains a movable ram to force the waste to be incinerated downwardly against a transversely extending, rotatably driven bar at the top of the combustion chamber. Combustion temperature control is provided by feeding air into the combustion chamber and by rotating the bar to abrade char from the waste supported by the bar. A bed of ash is maintained within optimum levels for thermal protection of bottom of the combustion chamber.

Abstract: A system for allowing a robot to be moved and set up quickly to perform a variety of work tasks at different work locations is disclosed. Once roughly positioned at a work location, the robot uses position sensors to establish in its computer memory a set of coordinate axes which match precisely the intersections of the three planes of a reference structure which is in a fixed position relative to the work location. All robot movements required to carry out the work task are made with respect to this set of coordinate axes so that the work task program remains the same independent of the exact position of the robot. A sensor holder and sensor storage bracket which uses the straight line horizontal and vertical movement capability of the robot to permit a programmed pickup and storage of the sensor is disclosed.

Abstract: A cooking appliance, particularly adapted to heat boilable pouch packaged foods, employing incandescent electric lamps as a radiant heat source. Cooking is controlled without a timer by sensing expansion of the plastic pouch containing the food. Venting is employed which permits the appliance to be extremely compact while permitting the use of decorative wooden end panels which will not overheat.

Abstract: The inspection probe for inspecting tubular members comprises a plurality of axially oriented plastic strips which form the circumference of the probe with each plastic strip having mounted thereon an eddy current coil. A rubber tube is disposed on the interior of the plastic strips so that when the rubber tube is inflated, the plastic strips and coils are forced outward into close contact with the tubular member so that the eddy current coils can detect flaws in the tubular member. The eddy current coils are held against the tube wall even when the tube has been deformed into an irregular configuration.

Abstract: A molded case circuit breaker includes separable contacts, a conventional operating mechanism, and means for magnetically stretching the arc upon contact separation to provide current limiting action. In a first embodiment, the arc stretcher comprises three separate stacks of spaced parallel U-shaped magnetic plates each oriented to provide a slot parallel to the plane of the loop formed by an expanding arc. In a second embodiment, the U-shaped plates each comprise a plurality of coplanar interleaved magnetic plates electrically insulated therebetween and having extending members to form pins lining the sides of the slot formed by the stack of plates. Additional independent pins inserted into the slots of an arc chute are also provided. A third embodiment includes fixed and movable contact arms and conductive means attached thereto to provide current flow in opposite directions through the contact arms. The contact arms and conductive means are positioned and sized so as to provide positive arc positioning.

Abstract: A circuit breaker includes a slotted magnetic device having a plurality of spaced slotted conductive plates and a moving contact arm positioned within the slot when the circuit breaker is in a closed circuit position so that current flowing through the contact arm has a component in a vertical direction with respect to the slot. An overcurrent condition through the circuit breaker causes magnetic flux to be generated within the slotted magnetic device which develops a force to drive the moving contact arm from the front to the rear of the slot in a direction generally parallel to the bottom of the slot, thereby actuating the circuit breaker from a closed circuit position to an open circuit position. The circuit breaker also includes an arc-extinguishing device including a plurality of apertured conductive plates. The moving contact arm includes a probe member extending into the apertures of the plates when the circuit breaker is in a closed circuit position.

Abstract: An elevator system including an elevator car mounted for movement in a building to serve the floors therein. The deceleration control for stopping the elevator car accurately at a selected floor, regardless of load and direction of the elevator car, continuously adjusts the braking torque to provide the desired velocity versus time pattern, and the desired distance versus time pattern, wherein both the deceleration distance and the deceleration time are fixed quantities.
