IPC: H04L47/43
Filed: 1992-03-10
Abstract: A switch includes a plurality of memories respectively having write terminals connected to input ports and output terminals, each of the memories including an input acknowledgement signal generating block for generating an input acknowledgement signal when data is received thereto. A multiplexer, which is coupled between the read terminals of the memories and an output port, connects one of the memories to the output port in response to a port number signal.  An output controller, which is coupled to the memories and the multiplexer, receives the input acknowledgement signal from each of the memories in order of receipt and generating the port number signal so that data stored in the memories is selected by the multiplexer in order of receipt of the input acknowledgement signal.

Filed: 1992-04-01
Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for displaying alphanumeric and graphic messages in a flat medium using a small number of geometric forms is described.  In the example, triangular and parallelogram flat paving stones or tiles are fashioned at an appropriate size, and these are arrangeable into an infinite number of letter, number or graphic forms.  The same forms, produced in different colour, can make up the background.   Mathematically defined integer multiples of the sizes of the forms are also produced, and will interfit with the original size, making it possible to easily deal with situations requiring complex detail, shading or special weight-bearing.

Abstract: A queueing and dequeueing mechanism for use in an integrated fast packet network, wherein fast packets from differing traffic types are multiplexed with one another through use of a weighted round-robin bandwidth allocation mechanism (517). Fast packets within a particular traffic type are selected for transmission through use of a head of line priority service (514), a packet discard mechanism (516), or both. The weighted round-robin bandwith allocation mechanism functions, in part, based up-on a credit counter for each queue group that represents a particular traffic type.

Title: Method and apparatus for removing waste paper from a continuous web of photographic prints
Inventor: DOLF RICHARD A
IPC: B26D5/34
Filed: 1992-06-03
Abstract: Disclosed is a method and apparatus for removing wastepaper (W) from a continuous web (2) of photographic paper upon which photographic images (P1, P2 . . . ) have been printed. Between each photograph there exists a cut mark (4) that instructs a photographic print cutter (1) where one photograph ends and an adjacent photograph begins. The method comprises advancing the web to a point where a cut mark is expected and sensing the presence or absence of a cut mark. If a cut mark is sensed, the web is advanced to align the cut mark under a cutting knife (8) and the cutting knife is cycled. If a cut mark is not sensed, the web is reversed a predetermined reverse length before the cutting knife is cycled. By reversing the web the predetermined reverse length, it is assured that any length of wastepaper cut from the web will at least be as long as the reverse length. The reverse length is long enough to prevent jamming of the print cutter.

Title: Surface adjustable bent housing
Inventor: ASKEW WARREN E
IPC: F16L27/08
Filed: 1992-06-26
Abstract: ABSTRACT OF DISCLOSURE In accordance with an illustrative embodiment of the present invention, a surface adjustable bent housing for use in a downhole drilling motor assembly includes a lower housing that is coupled by a threaded connection to a mandrel that is pivotally mounted in an upper housing by a ball-type joint and a pair of radial keys. A stack of rings having inclined end faces is mounted on the mandrel between the opposed ends of the upper and lower housing members so that the relative orientation of the rings creates a bend angle in the assembly that is rigidly maintained when the threaded connection is tightened against the rings, Longitudinal splines are used to couple the rings to the mandrel, which are selectively released during adjustment. Compressive loads due to bending moment are carried on the outer annular surfaces of the rings to provide a relatively stiff joint.

Abstract: A method and an apparatus for on-line monitoring the quality of a purified metal sulphate solution is disclosed.  The method comprises the steps of depositing metal from the purified metal sulphate solution onto a working electrode submerged in the solution by passing constant current through the solution at a current density in the range of 25 to 150 mA/cm2 for a predetermined time interval, dissolving the metal deposited on the working electrode by reversing the polarity of  the potential applied between  the working  electrode and a  counter electrode so as to pass a reverse current of the same current density through the solution until all zinc is removed from the working electrode as sensed by a sudden change in electrode potential, deriving the quality index of  the  solution  by  calculating  the  ratio  of  the dissolution time over the deposition time, and restoring the surface of the counter electrode by effecting the dissolution  of  the  metal  deposited  on  the  counter electrode at the end of each measurement.
