Patent number: 4264213Abstract: In storage apparatus wherein asphalt hot mix is moved by gravity along a chute from the top of a bucket elevator to the inlet of a batching hopper at the top of a storage bin, a baffle in the chute, over the inlet, prevents segregation of mix entering the hopper. The baffle is spaced forwardly of the front end of the chute bottom wall, is oriented generally vertically and transversely to the length of the chute, and is flatwise swingable backward and forward. By means of a set screw through a front wall of the chute the position of swinging motion of the baffle is so adjusted that coarse mix components, carried against the baffle by momentum, are deflected by it towards the center of the hopper. Adjustable remixing baffles in the chute, adjacent its side walls and behind the front end of its bottom wall, deflect material away from the chute side walls to effect remixing of aggregate that became segregated during its charging into the bucket elevator.Type: GrantFiled: June 13, 1979Date of Patent: April 28, 1981Assignee: Bituma-Stor, Inc.Inventor: Bruce A. Dillman

Patent number: 4058223Abstract: A pin is integral with a diaphragm and extends from one side of the diaphragm. The other side of the diaphragm is subjected to a pressure or vacuum to create a pressure differential across the diaphragm to move the pin into or out of engagement with an article within a controlled environment. The diaphragm isolates a fluid, which produces the pressure differential across the diaphragm, from the controlled environment. In one embodiment, the pin is formed at the center of the diaphragm and moves only in a straight line. In another embodiment, the pin is formed eccentric to the center of the diaphragm so as to have a combination movement of angular and straight. The pin can be employed to stop an article such as a semiconductor wafer, for example, or to raise or to lower the wafer without the actuating fluid contaminating the controlled environment in which the semiconductor wafer is disposed.Type: GrantFiled: June 19, 1975Date of Patent: November 15, 1977Assignee: International Business Machines CorporationInventor: Bernd Cruse

Patent number: 3982619Abstract: Flow control apparatus and method for controlling the flow of gravity fed substantially cylindrical objects through a gravity runway wherein a starwheel, a star-shaped ferrous pulse rotor and a ferrous rotor are each spaced from each other and axially fixed to a free wheeling shaft mounted in a frame connected to a gravity runway such that the starwheel lobes jut into and rotate through the gravity runway. Each starwheel lobe engages each of a successive line of gravity cans as the cans fall through the runway. A magnetic sensor is mounted on the frame near the star-shaped pulse rotor such that as cans free fall past the starwheels and rotate the free wheeling shaft star points on the pulse rotor rotate past the sensor and disturb the sensor's emitted magnetic field. For each disturbance, the sensor emits an electrical pulse signal.Type: GrantFiled: October 1, 1975Date of Patent: September 28, 1976Assignee: American Can CompanyInventors: Walter Joseph Sieverin, Donald Henry Ruge
