Abstract: ABSTRACT:              Digital signal processing arrangement such as a digital filter for computing output signal samples which are each equal to the sum of products of a given plurality of pairs (for example N) of input signal samples. One of the input signal samples of the pair is, for example, formed each time by a sample x(n) of a digital signal to be fil-tered, the other input signal sample of the pair by a fil-ter coefficient z(n), wherein either the sample  x(n) or the filter coefficient z(n) can assume only a limited number of values O, ?A1, ?A2, ... ?AM, M being much smaller than N. In the case x(n) can assume only this limited number of values, z(n) is  first multiplied, owing to the x(n) be-longing to the pair, by the sign of x(n) for generating a product of the form z(n).sgn [x(n)]  . In-dependent of the magnitude of x(n) this product is applied to an accumulator which corresponds with this magnitude of x(n). After all N products have been applied to one  of the M accumulators the partial sums stored therein are  multiplied by the mag-nitude  ¦x(n)¦  corresponding therewith and the products obtained are added together.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to apparatus for ultrasonically measuring physical parameters of flowing media.  A measuring path has two ultrasonic converters with transmitting and re-ceiving devices being connected to the converters.  The path has at least one component in the direction of flow and over which ultrasonic signals are sent alternately upstream and downstream.          A comparator unit connected to the receiving device has an in-put for a reference signal from the control unit applied there-to at a predetermined time after the time of the transmitter starting signal.  The comparator unit generates early or late signals when arrival signals from the receiving device come in earlier or later than the reference signal.  A first signal level generator connected to said comparator unit produces a first main signal related to the velocity of sound in said media.          A second signal level generator connected to the logic circuit for producing a second auxiliary signal related to the flow velocity of said media.  A summating circuit has inputs con-nected to the first and second generators.  Switch and re-versing amplifier units between the summating circuit and the second signal level generator are controlled by the auxiliary flow velocity signal to and from the summating cir-cuit to provide sum and difference outputs for the summating circuit.

Abstract: ABSTRACT OF THE DISCLOSURE            A poker-Keno-type game which can be played by one or more persons. The game comprises a Keno-like "goose" containing fifty-two balls each bearing the representation of a card in a conventional deck of playing cards. After the balls are mixed or shuffled in the "goose" to assure randomness, a number of balls, corresponding to the number of cards dealt in a poker hand (e. g. five cards), are blown into "rabbit ears" in consecutive order. The results of the foregoing procedure are displayed on at least one game board. Prior to the initiation of the game, each player uses a slip in attempting to guess, for example, if one or more of the cards has a value of "9" or better with Aces being high, or a value of "2" through "7" being low.  Each player can also use the slip to guess if the hand contains conventional poker combinations such as a straight,  a flush, a full house or the like.

Abstract: Abstract of the Disclosure Foam is produced electrolytically in a liquid having foaming tendencies through the use of closely spaced electrodes of opposite polarity that are disposed in substantially upright dispositions within the body of liquid being treated.  The electrodes extend from a position deep within the body to a point at or above the surface of the body, and the electrodes are so formed or are associated with such other structure that bubbles generated within the columnar treating region between the electrodes cannot escape from the electrodes until reaching the surface of the liquid, thereby being confined and exposed to the electrodes throughout the full extent of travel by the bubbles to the surface.  By regulating the positions of the bubble outlet relative to the surface of the liquid, the characteristics of the foam produced from the bubble discharge may be varied, e.g., locating the point of bubble discharge a very slight distance above the surface of the liquid produces a creamy, relatively viscous foam having small diameter bubbles compared to the foam produced with the discharge at a more elevated position in which instance bubbles of larger diameter appear in the foam.
