Title: Coaxial plug and socket connector for coaxial cable - has connection for the outer conductors made from solid tubular sections with longitudinal identation(s)
Inventor: MARGREITER HANS
IPC: H01R9/05
Filed: 1979-06-08
Abstract: The connection between the outer conductors of the cable to be jointed is made from solid tubular sections (9, 37), one fitting inside the other. There are no slits in either tube. Instead, one tube, pref. the outer (9), has longitudinal indentations (39) which protrude radially inwards and bear against the outside of the mating section (37). These indentations (39), typically three spaced at 120 deg. intervals, and the tube thickness are so dimensioned that when the parts are pushed together there is sufficient spring pressure to give an electrically and mechanically stable contact. In order to give easy entry for the inner tube (37) the indentations stop short of the end of the outer tube (9). The arrangement is mechanically stronger than in designs with an axial slit to give the spring effect. It is thus less prone to distortion by misuse.

Title: Absolute rotation speed measurement - using monochromatic light ring with single sideband modulation of opposed partial light beams
Inventor: RUSSER PETER DR
IPC: G01P3/36
Filed: 1979-08-29
Abstract: An absolute rotation measuring arrangement uses the Sagnac effect. It involves dividing a monochromatic light beam into two approximately equal intensity partial beams. These pass through an optical fibre and in opposite directions along a light path, are modulated, and recombined before being fed to a photodetector. The arrangement enables very accurate measurement to be achieved using conventional single sideband modulators. Both partial beams are modulated in single sideband modulators with frequencies f1 and f2. As they pass around the light path they exhibit a frequency difference f2-f1. The frequency of one modulater is varied to maintain either a constant or maximal detector output signal from which the rotation speed is derived using measurement constants C1,C2. The speed is equal to C1(Fl-f2)+C2.

Patent DE-3004552-A1 (DE)
Inventor: JAEGER HORST
IPC: H04M7/10
Filed: 1980-02-07
Abstract: By means of a method for exchanging switching signals in the connection traffic in telephone networks, a check of both ends of a link is intended to be enabled in simple fashion following the transmission of a long-distance call-barring signal prior to the release of the corresponding transmission. Once the long-distance call-barring signal (HKFH or HKFU) has been deactivated, it is established that the connection line and the associated transmission to the distant station are ready for operation. For this purpose, a signal string (HKA, HKE) which effects a connection cleardown and which corresponds to the direction of transmission is activated prior to the release of the corresponding transmission circuit of the first (HA) or second (UA) system by the second (UA) or first (HA) system. The long-distance call-barring signal (HKFU) then replaces the first signal (HKA) of any signal string (HKA, HKE). <IMAGE>
