Patent GB-2060682-A (GB)
Title: Hydrocarbon reforming process using platinum/rhenium-containing catalysts
IPC: C10G59/02
Filed: 1980-10-08
Abstract: A process wherein, in a series of a reforming zones, or reactors, each of which contains a bed, or beds of catalyst, the catalyst in the leading reforming zone(s) or reactor(s) comprises supported platinum and a relatively low concentration of rhenium, and the catalyst in the last reforming zone(s), or reactor(s), of the series, comprises platinum and a relatively high concentration of rhenium. The amount of rhenium relative to the platinum in the last reforming zone, or reactor, is present in an atomic ratio of rhenium:platinum of at least 1.5:1; preferably at least 2:1, and more preferably ranges from about 2:1 to about 3:1. The beds of catalyst are contacted with a hydrocarbon or naphtha feed and hydrogen, at reforming conditions, to produce a hydrocarbon or naphtha product of improved octane quality. The progressive increase in the atomic ratio of rhenium to platinum in passing from the leading zone to the last zone reduces the amount of coke deposition on the catalyst at given reforming conditions.

Patent GB-2070385-A (GB)
Title: Adaptive amplitude averaging for weighting sampling noise
IPC: H04N9/64
Filed: 1981-02-06
Abstract: An apparatus reduces quantizing noise by averaging samples of picture information only when only low frequency information is present. Thus, high frequency detail is not lost. The non-reduced noise is less noticeable when high frequency information is present. The absence of high frequency information is determined by looking (44, 54) at proximate samples to see if their amplitudes are within a selected amount of each other. The averaging typically is of two (32, 34) or four (32-38) picture samples depending upon how great an area has only low frequencies, but greater numbers of samples can be used. The number of proximate samples taken for the determination may be the same number as that taken for successive averagings. Figure 8 shows the sample values, multiplied by four, for a uniform zero input video signal, produced by the addition to the video signal of a weighting on offset signal, to reduce false contours. <IMAGE>

Filed: 1982-07-01
Abstract: A diplexing orthogonal mode transducer for isolating the signals which are transmitted and received in the two different frequency bands of a satellite communications system comprises a smooth walled inner waveguide (1) which is partly overlapped by a coaxial outer waveguide (2) having an internally corrugated section (2b) adjacent the aperture (4) of the inner waveguide arranged so that signals in the higher frequency band are confined to a central region coupled with the inner waveguide (1) and signals in the lower frequency band are confined to a peripheral region which couples with the section (2c) of the outer waveguide surrounding the inner waveguide (1). The annular section (2c) of the outer waveguide splits into four evenly arranged branches (5) which peel away from the inner waveguide (1) and transform smoothly into rectangular waveguides (6), the orthogonal polarisation components of received low frequency energy being isolated and conducted away by the branching waveguides (5, 6). The internal corrugations are dimensioned to present a capacitive reactance to the higher frequency signal and an inductive reactance to the lower frequency signal. Each branch (5) is provided with a central rib (7) along its inner wall, the ribs (7) commencing on the outside of the inner waveguide (1) before the outer waveguide branches. <IMAGE>

The float (17) is incorporated in a float chamber (14) built into a boat (13), a buoy or the like, the chamber having a water inlet pipe (5) open toward the water. The generator (21) and motion-transferring mechanism (26-45) are disposed in a housing (1) which also comprises the float chamber (14). The housing is preferably mounted in a cradle-shaped step bearing (4) which can be mounted in a boat, buoy or the like, which permits the position of the housing (1) and thereby the float chamber (14) to be adjusted about the axis of the cradle so that the float chamber can be brought into a desired vertical position independently of the slope of the boat hull. <IMAGE>
