Filed: 1974-10-31
Abstract: 1444488 Radio signalling POST OFFICE 31 Oct 1974 [31 Oct 1973] 47240/74 Heading H4L A radio station for transmitting and receiving signals within a specified band, comprises means operative to respond to an incoming primary pilot signal to provide an automatic frequency control of the station, means operative to monitor the presence of the pilot signal and the presence of an incoming secondary pilot signal and means operative to transmit the primary pilot signal in response to the loss of reception thereof for a predetermined time and the continuing reception of the secondary pilot signal. As described, the station forms part of a system in which a plurality of earth stations using frequency division multiplex communicate via a satellite relay. One station acts as a master station and transmits the primary pilot signal to enable the remaining earth stations by AFC to correct for carrier variations due to Doppler shift &c. A second station acts as a back-up station and in the event of non- reception of the pilot signal, takes over as master station and transmits the primary pilot signal. However, this non-reception could be due to a failure in the second station and to resolve this uncertainty a third station transmits a secondary pilot signal which if received by the second station when the primary pilot signal is not being received, signifies that it is the master station which is faulty. A fourth ground station may monitor both the primary and secondary pilot signals and transmit the secondary pilot signal if it is not being received while the primary pilot signal is being received. To prevent dual transmission of a pilot signal which could occur due to an intermittent failure, a master station monitors both pilot signals and if it loses its own pilot signal while continuing to receive the other it disables the pilot signal transmitter.

Filed: 1974-11-06
Abstract: The preparation of novel 4-oxo-1-pyridinylpenicillin and -cephalosporin derivatives of the formula I, in which the substituents are defined in Claim 1, is described. The said compounds are prepared by converting a 4-hydroxypyridine into the corresponding silyl ether and then condensing this with an  alpha -haloacetamido beta -lactam. The novel compounds are utilisable as antibacterial active compounds, since they have a high degree of efficacy against a large number of microorganisms. The novel cephalosporin derivatives are particularly utilisable against penicillinase-producing microorganisms and can therefore be used as antibacterial agents in the treatment of infectious diseases which are caused by gram-positive and gram-negative bacteria in poultry and animals, including humans.

An electrical unit, e.g. a transformer coil is encapsulated in a two-stage process in the second stage of which it is supported in a mould by the encapsulating material formed in the first stage. In the first example, a coil is supported in a two-part mould by two retractable supports. The mould cavity is connected to vacuum and the encapsulating material, e.g. a silicone rubber, is supplied under pressure. Selected areas of the mould are heated and cooled so that the encapsulating material remote from the supports is cured, whereas the material adjacent the supports remains uncured. The supports are now retracted leaving the coil supported by the cured resin, fresh encapsulating material is supplied to the mould and cured by heating of selected mould areas. In another example, a transformer coil is supported in a first two-part mould by parts of the mould on a layer of the encapsulating material, a further layer of material is applied to exposed parts of the coil and the mould is closed and curing is effected at selected areas. The coil is then transferred to the bottom part of a second twopart mould, the exposed part of the coil is coated with encapsulating material, the mould closed and curing is effected at the required areas. In a further example, a tape of encapsulating material is mounted in a two-part mould selected areas of which are heated and cooled so that the tape has a pheripheral uncured zone and a central curved zone. The coil or unit to be encapsulated is then located in a two-part mould by said tape and encapsulating material, of the same kind as that of said tape, is supplied to the mould cavity.
