Patent ES-322908-A1 (ES)
Title: Improvements in devices for stabilising the resonant frequency of cavities, as a function of the temperature
IPC: H01P7/06
Filed: 1966-02-11
Abstract: A cavity resonator is compensated for changes in resonant frequency due to temperature variations by means of an independent piston supported upon members which are deformable under the influence of the temperature variations. As shown, a cavity 601 of the re-entrant type (part only shown) is tuned by axial movement of the re-entrant portion 602 which, for this purpose, is threaded into a radially compressible collar 609 carrying an internally bevelled lock-nut 616. A coaxial temperature-compensating piston 604 is carried upon a rod 607 screw-threaded into a guiding member 606 which slides axially within the tuning piston 602. The axial position of member 606, and hence of the piston 604, is determined by the length of three tubular temperature-responsive liquid-filled bellows 610 (two only shown) against which the member 606 is pressed by a spring 614. The end of the rod 607 is located by a flexible blade 671. Guiding member 606 is positively connected to the piston 602 by the bellows 610 so that rotation of the piston causes rotation of member 606 and axial movement of rod 607. Hence, the penetration of the piston 604 #e varies with the penetration a of the tuning piston 602. The resulting variation in compensation sensitivity with resonant frequency can be made to follow a given linear or other law by suitably choosing the pitches of screw threads 661, 631. In a modification, the bellows are replaced by stacks of arcuate bi-metallic elements (512, Fig. 5). In another embodiment the two pistons are manually and independently adjustable.
Patent ES-337882-A1 (ES)
Title: Apparatus for Plasma Production and Interaction
IPC: H05H1/22
Filed: 1967-03-11
Abstract: In a nuclear fusion device, plasma beams are formed, and react with each other, in the cavity 10. The gas in the cavity is ionzed by an H.F. electric field formed by the resonating, in the TE 112 mode, of the cavity, excited by klystrons 14, 141. The electrons are attracted to the medial plane and so form the identical plasma beams which pass through each other and oscillate in the central zone. Axial containment is effected by magnetic microns formed by windings 24, 241, 26, 261. A radial magnetic field is formed by conductors 28. Injection of ionized gas is effected by the focusing of a laser beam a lithium hydrate within the cavity 10.

Patent ES-440696-A1 (ES)
Title: Data and signaling multiplexing in PCM systems via the framing code
IPC: H04J3/12
Filed: 1975-09-03
Abstract: A subsystem is added to an existing PCM system to provide N additional data channels and to increase the number of signaling channels. The subsystem includes a framing code generator to produce a framing code having a data code bit position for each of 6N system frames with certain of the bit positions having a distinctive pattern of code bits to provide frame synchronization for the receiver of the existing system and the receiving portion of the subsystem. The N additional data channels are time multiplexed by timing signals from the frame code generator and then the frame code generator inserts each channel of N time multiplexed channels into a different one of N others of the code bit positions to convey the additional data in the framing code without altering the distinctive pattern of code bits. The framing code generator also provides other timing signals to increase the number of signaling channels. A framing code receiver of the subsystem recovers the additional data channels from the framing code, the additional signaling channels and synchronizes the system and subsystem in response to the distinctive pattern of code bits. The subsystem may be converted to Western Electric D2/D3 compatibility by opening a strap on each of the framing code generator and framing code receiver.
