Abstract: ABSTRACT :                The invention relates to a commu-tatinn device for the selective control of data transport. There are two data inputs and two data outputs, each of the latter comprising a buffer for storing, for example, each time a data word. A number of possibilities of data transport can thus be selectively controlled, i.e. four for a single connection and two different ones for pair-wise connection. There are also provided, for example, seven input control lines, i.e. two lines for receiving a signal which indi-cates whether information is present on the asso-ciated input line, two lines for indicating the se-lected output buffer, two erase lines for making a data buffer freely accessible after output of data from the data buffer, and one priority line for granting priority to one of the two input lines if both lines select the same data buffer.          There are, for example, four output control lines, i.e. two lines which indicate that the data present on the input lines have been taken up in the selected output buffer, and two lines which indicate whether an output buffer contains data. Commutation devices of this kind can very quickly realise the data transport itself and can, moreover be grouped in a specific arrangement in order to form a breathing buffer or a device in which the data partly determine their own path (for example, in the case of sorting or associative searching).

Abstract: ABSTRACT  OF THE DISCLOSURE.      Apparatus and method for sorting scrap metal pieces dependent on the type of metal therein.  The apparatus includes a conveyor and feeding means to feed the scrap metal pieces on to the conveyor, together with an X-ray fluorescence detector to examine each metal piece and determine the type of metal as a result of the character-istic X-rays emitted.  A respective control signal is utilized to move pegs on the conveyor so as to permit the respective metal piece to exit from the conveyor along a respective path and to enter a bin for that particular type of metal.  In this way scrap metal pieces of different metal are collected in different bins for subsequent processing.

Granted: 1981-08-25
Abstract: ABSTRACT OF THE DISCLOSURE     Molten metallurgical slags are expanded by contact with water in a liquid or vapor state by passing the molten slag along a prefoaming or expanding through by delivering the slag to this trough via an intermediate trough which is shift-able along the prefoaming trough in order to vary the location at which the slag contacts the prefoaming trough and the expend-ing-agent film thereon in accordance with physical characteris-tics of the molten slag, especially its temperature and visco-sity.  From the pre-expanding or prefoaming trough, the par-tially expanded slag may be subjected to expansion by conven-tional means, e.g. a rotating drum which disperses the slag particles trough the air so that they can be collected in a completely expanded, dry and solidified state.

Abstract: ABSTRACT OF THE DISCLOSURE           Scroll apparatus for pumping liquids wherein recessed liquid transfer passage means are provided in the end plates of the scroll members.  The transfer passage means may be inner passages within the scroll involutes, outer passages outside the scroll involutes or a combination of inner and outer passages.          These passages are located and configured to be opened substan-tially immediately after the orbiting involute wrap has reached that point in its orbiting cycle to define three essentially completely sealed-off liquid zones.  These passages remain open at least until the liquid passages between the wraps are suffi-ciently large to prevent any substantial pressure pulsations within the scroll liquid pump.  The scroll liquid pumps may be operated to pump liquid radially inward or outward.

Abstract: APPLICATION OF                        JAMES V. DAVIDSON            ECCENTRIC ROTARY VALVE WITH CONTROL-IMPROVING            WING MEMBER                   ABSTRACT OF THE DISCLOSURE      The two supports for the plug in an eccentric rotary valve are joined and rotatively coupled by a wing member.  As the plug is rotated from its closed position on the cooperating seat by the rotation of a shaft fixed to one of the plug supports, the wing member lies in the fluid flowing through the valve.          This fluid flow causes the wing member to exert a rotative force on the shaft in the direction to move the plug in its valve-opening direction.  This force shifts the inherently unstable control region of a rotative force, which the fluid flow causes the plug to exert on the shaft, and thereby extends and widens the range of plug positions in which an external rotative force applied to the shaft, as by a valve actuator, can uniquely determine, and exert exclusive control over, the shaft and plug positions.

Abstract: Abstract of the Disclosure A process is described for sealing anodic coatings on aluminum and the alloys of aluminum while simultaneously impregnating the anodic coating with organic resin during the sealing operation, thereby providing a protec-tive coating to the anodized aluminum which, among other things has superior corrosion resistant characteristics. A specified water-borne resin coating material possessing excellent stability at temperatures in excess of 170°F is used to convert the unsealed anodic coating to the monohydrate/trihydrate form of aluminum oxide during the sealing step of an otherwise conventional aluminum anodizing process. Subsequently, the sealed anodic film is cured at temperatures up to 500°F. This process provides a total protection system having characteristics superior to separately sealed and organically primed aluminum obtained through conventional processing.
