Abstract: This invention relates to a method for converting a binary coded data signal into a pulse frequency modulated code (P-F SK), where the frequency is that of a transmitter clock when the data signal is low (high), and half that frequency when the data signal is high (low), and where the code always changes state when the data signal changes state. The highest code frequency is obtained by combining the data signal with the clock signal to produce two signals of half the clock frequency, which two signals are applied to an exclusive OR gate.

Abstract: There is disclosed herein a signalling system between two units for a data transmission system which transmits digital data messages character by character between these two units. The signalling system includes a transmitter-receiver disposed in each of the two units having a control output for controlling the data transfer registers of the corresponding one of the two units. These transmitters-receivers are connected by two wires. The first wire permits transmission of clock pulses for synchronization and the second wire permits the transmission of signalling by means of the presence or absence of a current at predetermined bit times of the data characters.

Abstract: A switching network for multistage switching systems using IC techniques is proposed in which each switching matrix is selfsufficient, i.e. operates independently during both path finding and marking. This is accomplished by a selection circuit inside each switching matrix which circuit can be easily combined with the other logic elements for passing on offering and catching signals to form an integrated circuit.

Abstract: Ultrasonic remote control device for television receivers. In the one stepping direction only control steps of odd, and in the opposite direction only control steps of even ordinal number are used. During the control operation alternate steps are skipped until an overshoot condition is reached at which point one reverse step brings the control to the desired position. This results in an increased number of steps, in a control of finer graduation and in a rapid reset.

Abstract: The conductor cross-section of hollow power cable is changed in accordance with varying heat conductivity conditions along the line. The hollow inner section is decreased in diameter by adding conducting material to provide increased internal heat conductivity in areas of low external heat conductivity. The outer diameter remains constant. One variation uses a smaller diameter helical conductor to support added outer wire conductors. Another type uses an inner perforated pipe of different diameters and added layers of profiled wire conductors. The transition is graded to avoid sudden changes. The hollow inner duct may be filled with a coolant such as oil.

Abstract: An elevation measuring device for an air navigation system which includes a ground beacon using a commutated array transmitting successively from one radiator element at a time. One element of said array acts as a commutating cycle beginning marker and as a phase and amplitude reference. The airborne receiver imposes a programmed amplitude and phase modulation on successive sets of received pulses to simulate a scanning beam and effects a comparison of measured absolute values from pulse set to pulse set to produce elevation angle information. The first such set represents a first fraction (first half for example) of the array elements and the second set represents the remaining array elements.
