Granted: 1994-01-18
Abstract: ABSTRACT OF THE DISCLOSURE         In a television receiver, a change in a horizontal frequency of an input television signal between a high frequency and a low frequency is detected.  A horizontal oscillation frequency, a horizontal deflection drive pulse width, and a horizontal blanking period are changed in a first predetermined sequence in response to a change in the horizontal frequency of the Input television signal from the high frequency to the low frequency.  The horizontal oscillation frequency, the horizontal deflection drive pulse width, and the horizontal blanking period are changed in a second predetermined sequence in response to a change in the horizontal frequency of the input television signal from the low frequency to the high frequency.  The first and second predetermined sequences are opposite to each other.

Abstract: A controller for a vending machine capable of selecting a mode in which the machine is made Possible to sell commodities even if change lacks. If a forced accep-tance switch sets a forced acceptance mode, Put-in coins are accepted even if no change can be paid. When the sum of the put-in coins arrives at a predetermined set selling price, the controller generates a selling enable signal. If the machine sells a commodity in response to the selling enable signal, it pays out change in the range of the sum in which change can be paid or within the sum of the coins remaining in change coin tubes. In this case, if the coins remaining in the change coin tubes do not satisfy the required sum of change, the overall sum of change is not paid out, but a user of the machine can get a desired commodity.

Title: Ultrasonic characterization of polymer melts under processing conditions
Inventor: PICHE LUC
IPC: G01N29/024
Filed: 1992-09-15
Granted: 1999-09-14
Abstract: A method and apparatus for ultrasonically characterizing a polymer melt flowing in a predetermined direction between two opposed parallel surfaces spaced from one another to define a gap filled with polymer are disclosed. Ultrasonic pulses are propagated through the polymer melt between the two surfaces in a direction normal to the direction of flow for interaction with the polymer, the ultrasonic pulses having a duration such as to prevent successive echoes from overlapping with one another while reverberating between the two surfaces. The time delay between two echoes exiting from the polymer melt and generated from each pulse having interacted with the polymer is continuously monitored while simultaneously monitoring amplitude variations of the two echoes, to provide output signals representative of ultrasonic velocity and attenuation in the polymer melt. These output signals are processed to obtain data comprising ultrasonic velocity and attenuation values measured simultaneously as a function of time. The data is then processed to derive quantitative information relating to viscoelastic properties, structure or composition of the polymer, which can be used as input data in a closed loop process control system.

Abstract: A clock phase signal of each time slot of a TDM signal is stored into a corresponding memory location and a clock phase signal of a subsequent time slot is read from a memory location corresponding to the subsequent time slot for recovering clock pulses. A decoder is synchronized with the clock pulses for decoding an encoded digital signal of each time slot to produce a decoded signal. The error rate of the decoded signal of each time slot is decoded and compared with a prescribed value. When the detected error rate is determined to be higher than the prescribed value, the write operation of the memory is disabled to prevent the clock phase signal stored in a memory location corresponding to the decoded signal from being overwritten with a subsequent clock phase signal.

Abstract: In order to extend the life of mixing impellers which circulate materials, and particularly which suspend solids, in the form of particles which erode the blades of the impellers and place a practical limit on impeller speed and/or angle of attack due to increased erosion at high flow velocity (erosion being a function of the cube of the velocity), the blades are constructed from blades into an airfoil configuration which does not limit the thickness of the plates and thereby allows the use of thick plates having extended life. An erosion resistant layer is located at least over the leading edge region of the blade and the shape of the blade reduces velocity of flow over the leading edge; the camber of the blade being maximized midway between the leading and trailing edge. The suction surface of the blade in the region subject to erosion is continuous thereby avoiding discontinuities which form vortices which enhance erosion. Fins, which may be at the tip on the suction side of the blade from midway between the leading and trailing edges to the trailing edge reduces tip vortices thereby further extending blade life in erosion-producing environments.

Title: Nonlinear dynamic substitution devices and methods for block substitutions

IPC: G09C1/00
Filed: 1992-08-04
Granted: 2001-05-29
Abstract: Method and apparatus for nonlinearizing modulo 2 addition (24) based encryption by block substitution techniques which allows use of the substitution scheme with relatively simple hardware and yet makes cryptanalysis more difficult. The basic block substitution (22), a one to one mapping of n bit binary numbers onto themselves, is based on the fact that certain permutations of the n bit binary numbers define a block substitution by modulo 2 addition (24) of one permuted set of numbers to another, and that a subset of these define equations having an additive relationship when viewed as vectors. This allows the simple changing of the transformation on a frequent basis. Then the equations ace nonlinearized, also in an orderly (34) and readily variable manner, so that the remainder of the set equations may no longer be generated from a limited subset of the equations. Various properties of the transformations and methods of using the same are disclosed.
