Abstract: An impeller pump including a housing (12) defining a seal cavity (26) having a shaft (20) rotatably mounted therein and an expeller (46) to pump fluid from the seal cavity. A dynamic seal (58) provides a fluid tight seal between the housing and the shaft. The seal comprises an axially movable primary seal ring (76) which rotates with the shaft and a mating stationary seal ring (80). Biasing means (96) urge the primary seal ring into sealing engagement with the mating seal ring (80). The radial face of the mating seal ring defines a plurality of spiral grooves (114). When the pump is operating, the primary seal ring rotates with the shaft and the grooves create a pumping action to pump air between the faces causing the primary seal ring to lift away from the mating seal ring to prevent wear and avoid undue heat generation.

Abstract: In a television transmission system a digital luminance signal Dy and two digital colour difference signals DCHR(1) and DCHR(2) are applied to a distribution circuit 3 at the transmitter end, which digital colour difference signals are applied thereto possibly after having been subjected to a vertical decimation operation with a decimation factor R. The distribution circuit 3 partitions all these signals into groups of Q samples per group. After receiving an even number of luminance groups and an even number of chrominance groups, a first half of this number of luminance groups and a first half of this number of chrominance groups is applied to a first auxiliary picture signal output 3(4) of the distribution circuit 3, while simultaneously the other half of the number of luminance groups and the other half of the number of chrominance groups is applied to a second auxiliary picture signal output 3(5) of the distribution circuit. A transformer for performing a forward two-dimensional Q*Q transform is connected to each of these auxiliary picture signal outputs.

Abstract: In a data transmission system with radio stations and devices remote from it, e.g. in a cellular mobile radio system, the radio stations transmit radio signals and receive radio signals which in each case contain data signals. According to the invention, as many as possible are shifted from the fixed stations to the remote devices for processing functions. The radio signal to be transmitted from the radio station (2) is generated by generating in the remote transmission device (10) an unmodulated carrier and a carrier modulated with the data signal, where the carriers differ in their frequency by the amount of the carrier frequency of the radio signal (f1). These two optical carriers are transmitted to the radio station (2), where they are mixed in an optical receiver to produce the radio signal containing the data signal. A radio signal which is received in a radio station (40) is optically transmitted to a remote device (44) and is further processed only when it is there. This transmission is carried out in that an optical transmitter (41) present in the remote transmission device (44) generates an unmodulated optical carrier and transmits it to an optical modulator (43) located in the radio station (40). In the optical modulator (43), the light, modulated with the received radio signal, is transmitted back and the radio signal (f1') is obtained by optical heterodyne reception of the unmodulated and the modulated carrier (v0', v1').
