Abstract: The present invention relates to a method and apparatus for simultaneous transmission of horizontal (H) and vertical (V) channels in a dual polarized weather radar. The goal of the invention is accomplished by placing the receiver, duplexer and polarizer equipment above the azimuth rotary joint but below elevation rotary joints. The elevation rotary joints and other associated signal paths are calibrated by using a low power signal on the radar's operating frequency that is fed into couplers above the elevation rotary joints.

Abstract: An apparatus for the manufacture of radiopharmaceuticals includes a lead chamber (6) and a loading device (5) on which a chemical system is mounted in the form of a disposable kit (5). The apparatus includes a first suspension device (9) which functions to move the loading device in a radiation-safe manner between a loading position externally of the lead chamber and a working position within the lead chamber. A second suspension device is provided for releasing a consumed disposable kit from the loading device, such as to enable the consumed kit to fall down into a bottom section (8) of the lead chamber, this bottom section serving as a waste chamber.

Abstract: Method and apparatus for measurement of the velocity of a moving target (20) in radio frequencies. From the measurement station (10) and from the target station (20), radio signals (S.sub.1,S.sub.2) are transmitted that are in different frequency ranges, as compared with each other, so that the receivers at the measurement station (10) and at the target station (20) are not subjected to interference. The radio signals (S.sub.1,S.sub.2) are received at stations (20,10) opposite to their transmission stations (10,20). The oscillator of the target station (20) is locked with the frequency transmitted by the measurement station (10) by means of a phase-locked loop (PLL). The frequency of said oscillator is passed to the transmitter part of the target station (20). The signal (S.sub.2) transmitted by the target station (20) is received at the measurement station (10). The Doppler shift (fd) of the frequency of the signal (S.sub.

Abstract: A method for measuring the velocity (v) of a moving target (A). Radio signals are transmitted by means of radio transmitter-receiver arrangements of both the measuring station (B) and the target station (A) and received at the opposite stations (A,B), the frequencies of which signal include Doppler shifts (fd) to be observed both at the measuring station (B) and in the measuring target (A). On the basis of the Doppler shifts (fd), the escape and/or approach velocity (v) of the target to be measured is determined relative to the measuring station (B). Radio signals are transmitted from the measuring station (B) and the target station (A), the frequencies of which signals deviate from each other by a relatively small frequency difference (fk) or by a Doppler frequency shift (fd), the absolute value of which small frequency difference remains at least as high as the absolute value of the largest expectable Doppler frequency shift (fd.sub.max).

Abstract: Method and device in the antenna and receiving system of a radio theodolite, wherein the radio signal arriving from the transmitter of the object (31) to be measured is received by means of at least three antennas (1 . . . n-1) in the antenna field (AK) as well as by means of a reference antenna (n). The signals received from said antennas are passed to the receiving system, being controlled and selected by an antenna-selection switch (10a). By means of said system, the phase differences between the signals of different antennas are detected and measured, on the basis of which phase differences it is possible to calculate the angles of incidence (.alpha.,.epsilon.) of the signals on the basis of the known coordinates of location of the antennas in the antenna field (AK). In the method an outer reference antenna (n+1) is used which does not belong to the antenna field (AK) proper. The phases of the antennas (1 . . .

Abstract: A telescoping torque transmitting shaft comprising a shaft having at least three longitudinally extending circumferentially spaced guide grooves and a sleeve axially slidably surrounding the shaft and having an inner counter groove opposite each guide groove. Torque is transmitted between the shaft and the sleeve by a row of balls for each guide groove, each ball being partially received in its guide groove and partially received in the counter groove opposite its guide groove. At least certain of the balls in one row are of resilient elastic material; all others are substantially harder. Bias imposed upon the shaft by the resilient balls, urging the shaft in one lateral direction relative to the sleeve, maintains every ball in torque transmitting contact with both the shaft and the sleeve, while the harder balls in the other rows, by such contact, maintain the elastic balls compressed for exerting such bias.
