Abstract: A reinforcement assembly to be impregnated with a plastic or rubber material for reinforcing an article, such as a pneumatic tire, the assembly having three layers of cords: a core layer, an intermediate layer and an outer layer. The intermediate layer and the outer layer have the same direction of winding and the same pitch. When the core layer is wound in the same direction as the intermediate layer, the pitches of these layers differ in such a manner that the ratio between the difference in the values of these two pitches and the larger value of these two pitches is at least equal to 0.30. In the intermediate layer the axis of each cord is arranged along a helix such that the ratio between the radius of curvature of said helix and the diameter of said cord is less than 75.

Title: Data communication system

Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE          A device is placed intermediate a data transmitter, such as a facsimile machine and the public switched telephone network, and selectively processes the calls in a predetermined manner.  The signals sent by the transmitter are monitored by the process intermediary and when a particular type of signal is identified, the device processes this signal in a different manner.  For example, a particular type of signal could be a long distance signal whereupon the device stores the long distance number, supplies a current back to the transmitting device indicating that the connection has not yet been made, and then completes a call to a data transmission network with the process intermediary then connecting the data transmission network with the transmitting device after the device has transmitted the long distance number to the data transmission system.  The transmitting device believes the data transmission system is the identified receiver and the data transmission system will transmit the required protocol signals to the transmitting device whereafter the signals then are transmitted in the normal manner.  The data transmission system will then transmit this signal through the data transmission system to a regional location and then retransmit the data over telephone lines to the receiver.  The present invention also relates to the combination which includes modified transmitters, receivers, the public switched telephone network and the data transmission system which cooperate to transmit the data from the transmitter to the receiver in a more efficient manner as well as the process by which this combination transmits the information.  A modified data receiver is taught which is actuated by means of a non-telephone communication link and the receiver does not require a dedicated line.  The modification can be in the form of a process intermediary for use with existing receivers.

In a DPCM coder, wherein respective prediction values (s) are subtracted from digitized picture element signals (s), the difference signals that result represent the prediction error .DELTA. supplied to a circuit element for outputting a quantization error (11) pertaining to a difference signal.  In a following adder, quantization errors (q) are added to the prediction errors ( .DELTA. ), whereby the quantized prediction error ( .DELTA. q) can be taken at the output of the following adder.  For forming the  reconstructed  picture  element  signal  (sR), the quantization error (q) is  added to the current picture element signal (s) in a first adder and is supplied to a  first subtraction means via a predictor.    In an embodiment of the circuit, a DPCM structure that has a shortest possible ciritcal path for a DPCM structure that is composed of a quantizer, of an addition and of a register can be produced by dividing the predictor upon insertion or removal of individual registers.
