Abstract: A control method for the carrier wave of the FM synthesizer for a radio telephone system and a corresponding circuit with a processor (16), a crystal oscillator (15) in the processor, a digital/analog converter (18) and a counter (14) and with connection to the control voltage (Vohj) of the voltage-controlled synthesizer crystal oscillator (1) and with connection to the synthesizer intermediate frequency (IF2), the voltage-controlled synthesizer crystal oscillator (1) being controlled in this circuit by locking (synchronising) to the carrier frequency (fin) of the signal transmitted by the base station and received. In the circuit, the telephone processor (16) uses the counter (14) to count periods of the receiver intermediate-frequency signal (IF2) during the constant time T and obtains as a result a particular number (M) which is subjected to digital/analog conversion, the voltage obtained being used for controlling the voltage-controlled crystal oscillator (1) of the synthesizer. In the locked state, the control number (M) does not change with different counts. <IMAGE>

Abstract: The invention provides a method for the production by welding of a heat exchanger pipe starting with a round metallic pipe onto which external metallic fins are secured so as to be perpendicular to the axis of the pipe. Each metallic fin is produced in two halves in such a manner each fin has a coxial semicircular recess or bay whose radius mateches the external diameter of the metallic pipe and on each side of such recess there are two side surfaces so that after mounting the fin halves on the pipe there is a small gap at the parting line between the two halves. After mounting the two fin halves on the metallic pipe the respectively radially outer and parts of the gap are spot welded together and on cooling down the fin the fins shrinkage at the weld spots causes the two fin halves to pressed on the pipe with their recess boundaries engaging the outer surface of the pipe.

Abstract: Method which involves determining the position of a number of measured objects (5, 7) by determining a number of directions to the measured objects from at least two measuring stations (1, 3, 101, 102), of which at least one is mobile, the method being used to decide which of the points of intersection (112 - 115) between the directions correspond to measured objects and which ones do not correspond to measured objects. Changes in the mutual movements between the measuring stations and the points of intersection are in this case determined by comparison between the paths in which the points of intersection and the measuring stations are moving. The points of intersection whose movement is not affected by changes in the movement of other points of intersection, or by changes in the movement of at least one measuring station, correspond to positions of measured objects. <IMAGE>

Abstract: A dual chamber cardiac pacemaker has a pulse controller for delivering stimulation pulses to the ventricle of a heart, a ventricular sensor for sensing ventricular depolarization, and a unit for identifying a beginning of an A-V interval of the heart. The pulse controller causes a ventricular stimulation pulse to be generated at a predetermined energy level after the expiration of a predetermined A-V interval. The controller prolongs the A-V interval under certain circumstances. Upon the expiration of the prolonged A-V interval, the pulse controller causes the ventricular pulse generator to emit a ventricular stimulation pulse at a higher energy level than the predetermined energy level to evoke a response in the ventricle. This allows the intrinsic heart activity to be detected and utilized, while ensuring safe pacing, as well as successful and reliable stimulation and maintaining a low power consumption during normal operation.
