Abstract: A connecting terminal (10) for electrical apparatuses such as lights, ovens, washing machines or the like is shown and described, having an insulating body (11) and conductor connecting contacts arranged therein, at least one of which is a protective conductor contact (16), having an externally-located two-limbed connector (21), which is stamped from a thin, flat sheet and which passes through the wall of the insulating body (11) facing a terminal support (23) for direct contact engagement in an insertion opening (22) of the terminal support (23) and can be connected or is connected via connecting limbs (27, 28) to cut-outs (29, 31) in a positively locking or clamped- fitting manner. In the case of such a connecting terminal, a particularly secure connection of the connector (21) to the terminal support (23) is achieved according to the invention in that both limbs (25, 26) of the connector (21) make transitions into the connecting limbs (27, 28) and the connector (21), with the connecting limbs (27, 28), forms a component which overall has an essentially U-shape, and in that the unobstructed width (33) of the insertion opening (22) in the terminal support (23) is at least slightly smaller than the maximum spacing of the narrow external edges of the limbs (25, 26) of the connector (21) from one another.

Abstract: A loaded antenna (11) comprises a wave source (12) of an arbitrary polarized wave, a reflector (13) disposed near the wave source (12), with the surface opposite to the wave source (12) limited in area, and a dielectric (14) disposed on the opposite side of the reflector across the wave source (12), at least with the surface opposite to the reflector (13) formed parallel to the reflector (13). 
     By properly selecting the mutual interval among the dielectric (14), wave source (12) and reflector(13), the dimension and the dielectric constant of the dielectric (14), the vibration component in the running direction of the wave within the dielectric (14), the vibration component in the direction vertical to the running direction, and the vibration component between the reflector and dielectric are superposed, so that the electromagnetic field distribution in the vicinity of the dielectric (14) is made uniform. Thereby, high gain and high efficiency are realized, and the structure may be notably reduced in size.

Abstract: A ring for circulating multiple packets each containing control information and data such as digitised audio, includes a monitor system for preventing the unwanted accumulation of "full" packets in the ring which have already circulated once and have consequently fulfilled their function. Each node normally cancels all packets it has originated, after one circulation of the ring. In case this system breaks down, a monitor node sets "on" a monitor flag in all the packets it receives and re-transmits and cancels any packets it receives which have failed to have been cancelled by the other nodes and in which the monitor flag is consequently still "on".

Abstract: A multiple access communications system comprises a node spacecraft GEO and several user spacecraft LEO₁ tO LEO n . Each user spacecraft LEO₁ to LEO n  includes a transmit/receive terminal head 18₁ to 18 n , and the node spacecraft GEO includes n transmit/terminals 22 to 22 n  and a single beacon unit 24. The beacon beam may be operated to initiate acquisition phases which allow two-way communication to be established between the transmit/­receive terminals 22₁ to 22 n  on the node spacecraft and the transmit/receive terminals 18₁ to 18 n  on the corresponding user terminals. The acquisition phases include a period during which the beacon scans an uncertainty cone associated with the node spacecraft. This scanning period is reduced for second and subsequent acquisitions by using the first and subsequently acquired communication links to provide a more accurate estimate of the angular attitude of the node spacecraft, thus reducing the extent of the uncertainty cone.
