Abstract: A nuclear magnetic resonance gyroscope has a light source 10 which illuminates a magnetic resonance cell 28. The resonance cell contains a gas or vapour of optically pumpable substance and nuclear moment gases. The light not absorbed in the resonance cell is modulated in intensity and transmitted to a detector 40, which puts out an electric signal 89. Of special interest are the modulations which have Larmor precession frequencies, which are discriminated in a signal separator 110 whose output signal indicates the respective precessional frequency of the nuclear moment gases and their difference frequency. By means of a frequency comparator 134, the angular displacements of the gyroscope are detected as a function of phase changes in the precessional frequency for at least one of the nuclear moment gases. <IMAGE>

Abstract: The invention relates to a pin (21) for connecting an electrical conductor (2) to a PCB (4). The pin has a first part (24) thrust into a hole in the PCB and a second part (26), to which the electrical conductor (2) is connected by a sliding contact (8). The cross-sectional dimension (d2) of the second part (26) is greater than the cross-sectional dimension (d1) of the first part (24), and between these parts the pin (21) has a shoulder (27) with sharp edges. The hole in the circuit board is coated with a metal which is connected via tabs (22) to electrical conductors (3) of the PCB(4). The pin (21) is soldered in the hole with the aid of soldering metal (25) and flux. When the flux is heated it creeps along the surface of the pin. During soldering, the shoulder (27) with the edges prevents the flux reaching the second part (26) of the pin (21 ), the second part having contact surfaces (29) on the pin (21) against the sliding contact (8) and where the flux would be a contact resistance. The pin (21) has the advantage that its first part (24) is narrow and that the tabs (22) can have a small outside diameter. There is thus created room for a large number of conductors (3) between two adjacent pins (21).

Abstract: The present invention relates to a method and apparatus for through-connecting in a digital time switch a wideband connection including two or more channels. Each of the channels utilises a specific time slot in each frame coming into the switch, and a specific time slot in each frame departing from the switch. The problem solved by the invention is that the contents in certain outgoing time slots are delayed by one frame, whereas the contents in other outgoing time slots (so-called undelayed slots) are not delayed, which causes the information sequence in outgoing slots to be mixed up in relation to the information sequence in corresponding incoming slots, whereby the transmitted information is distorted. The method solving said problem involves that the content in delayed slots is read out from a speech store, the contents of which are in phase with the contents in an incoming frame, while the contents in undelayed slots is read out from an extra speech store, the contents of which are delayed one frame in relation to the contents in the incoming frame. The contents in undelayed times slots are thus delayed by one frame so that the contents in all time slots departing from the wideband connection are delayed by one frame, resulting in that the information is connected through the switch without being distorted.
