Abstract: A b s t r a c t The invention is related to a method and an apparatus for measuring the flow velocity of a flow, stream or jet of molten radiation emitting material, in particular a freely falling jet of molten glass. The intensity of the radiation emitted from a limited section of the material flow is detected by means of two radiation detectors at two separate locations mutually spaced apart by a predetermined distance along the flow path of the material flow. From the output signals of the two radiation detectors all pulse-like amplitude variations having an amplitude exceeding a pre-determined magnitude are discriminated. These pulse-like amplitude variations originate from randomly occurring, local, descrete, short variations in the intensity of the radiation emitted by the material flow caused by randomly occurring inhomogeneities in the material, for instance in the form of air bubbles in a jet of molten glass. The time interval between a pulse-like amplitude variation in the output signal from the upstream detector caused by an in-homogeneity in the material flow and the occurrence of a pulse-like amplitude variation in the output signal from the down-stream detector, which has been caused by the same inhomogeneity in the material flow, is measured and used as a measure of the travel time of the material flow between the detector locations for calculating the flow velocity of the material flow. Also the volumetric flow rate of the material flow can be determined by measuring also the diameter of the material flow with the aid of a linear array of photo diodes and calculating the volumetric flow rate on the basis of measured values of the flow velocity and the diameter.

Abstract: CAPACITIVE KEYSWITCH     Abstract of the Disclosure A capacitive membrane keyboard is described which has an upper flexible membrane with a first pattern of interconnecting conductive areas deposited on it at each key station of the key-board.  A second pattern of interconnecting conductive areas are deposited on a substrate below the first pattern.  At each key station the conductive lands are aligned with each other.  An electrically insulating spacer separates the pair of conductive lands at each key station when the keyswitch is unactuated.  In one embodiment of the keyboard a dielectric film layer lays over all of the bottom conductive land areas and over the entire lower second circuit pattern.          In another embodiment, a dielectric layer is deposited on at least one of the conductive lands at each key station which consists of a polymer dielectric film or other suitable dielectric coating.  In still a further embodiment, the lower and upper conductive areas may be made of an oxidizable metal, such as aluminum or tantalum, which has its surface oxidized in an oxidizing atmosphere to form a thin insulating dielectric layer on one or both of the lands of each key station.  An elastomeric cushion may rest on top of the upper membrane so that when the actuator of the keyswitch is depressed it will cushion the force of the actuator so as to protect the upper membrane and may provide some return bias force.

Abstract: ABSTRACT Much better control of the grind of a rotary mill and much more uniformity of grind of the mill is achieved by better control of air flow through the mill, provided by making the milled product collecting pan of the mill air-tight and regulating the amount of air allowed to escape from the pan. The apparatus of the invention includes a housing in which are mounted two discs in spaced, confronting axial alignment, each disc having extending therefrom toward the other disc concentric rows of teeth The rows of teeth overlap so that alternating rows of radially spaced, interposed teeth are formed. One of the discs is adapted to be rotated in relation to the other disc and grain to be milled, along with any air flow through the mill, is introduced through an inlet to the area between the discs inwardly of the innermost rows of teeth An outlet into a substnatially air tight collecting pan is provided for the milled material after it passes radially outwardly through the interposed rows of teeth An air control valve in communication with the collecting pan controls air flow out of the collecting pan which, in turn, controls air flow through the mill. Making the innermost row of teeth on the staionary disc, and makng them shorter than the other teeth, substantially prevents the throwing of pieces of grain back out through the inlet under low feed condition.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is a multiprocessor machine control system in which the failure of one of the processors to reset can be ignored by the rest of the control system. In particular, a software crash or other abnormality on one of the processors will generate a reset procedure. If the processor cannot be reset, this will indicate a processor board failure such as a hardware failure. If the processor and its controlled elements are not crucial to the machine operation, then the control will ignore the failed processor as though it were not in the control system, and continue with machine operation.
