Patent ES-310055-A1 (ES)
Title: Modulator circuit for pulse-modulated magnetron transmitters
IPC: H03C5/04
Filed: 1965-03-03
Abstract: A pulse modulator for a magnetron with means for blocking the circuit between pulses comprises a blocking oscillator T1 which is triggered by input pulses applied at terminal E and supplies positive square wave pulses which are applied via diode G2, capacitor C2 and transistor amplifier T2 to the gate electrode of a semi-conductor thyratron Thy which discharges a pulse forming network including inductors L1-L3 and capacitors C3-C5 through the primary of pulse transformer Tr2 having a secondary winding connected to the magnetron. On discharge of the network a second secondary of the pulse transformer provides an output pulse which charges C2 to a positive value in excess of any spurious pulses supplied by the blocking oscillator. The charge on capacitor C2 blocks the circuit for a period depending on the valve of R2, through which the capacitor discharges, and allows time for the thyratron to recover and for the pulse network to recharge.

Title: Apparatus for forming a beaded shell
IPC: B21D17/02
Filed: 1966-02-08
Abstract: A method of corrugating a hollow metal body of circular, elliptical or polygonal cross-section comprises forming corrugations by means of parallel rings of internal die-segments which are moved axially as they are expanded. Axial tension, produced by expanding the corrugations, may be used to move the dies axially, or (Fig. 1) they may be moved axially by the expanding forces applied, through a rod 49, by an hydraulic cylinder. The die segments (36), Fig. 9 (not shown), are held, by garter &c. springs 41, in tapered pockets 39, Fig. 3, in the opposed faces of rings 38a-38g which are carried by flanged sleeves 44 slidable on a support 31 fixed to a carrier 22. Rubber &c. O-rings 42 form the work-engaging surfaces of the die-rings, and bearing liners 40 are bonded to the segments 36 or the pockets 39. Axial movement of an end-plate 48 moves the rings 38b-38g axially and cams the segments 36 outwardly until the rings are in contact with each other. One or more of the die-rings may be made inoperative, Fig. 8 (not shown), by replacing two or more die-segments of the selected rings with others having tails (56) which extend inwardly and thus prevent relative axial movement between the cam-rings (38b, 38c, 38e, 38f) on each side of the diesegments.

Patent ES-358132-A1 (ES)
Title: Nuclear power plant protective system employing logic materices
IPC: G21C7/36
Filed: 1968-09-13
Abstract: In a nuclear reactor safety control system, the control rods are released so as to shut down the reactor, when variables monitored, such as primary coolant flow, water level, load and neutron flux, vary from predetermined values. Each variable is monitored by several, independent, sensing devices which are arranged in groups, each group containing one sensing device for each of the variables. Each sensing device energizes an associated relay coil during normal reactor operation and the coil is deenergized to fail safe when the undesirable condition of the variable monitored occurs. The contacts controlled by the relay coils are arranged in a number of independent matrices, each of which incorporates the contacts of some of the relays. This results in " redundant instrumentation " which permits correct operation of the safety control system when only some of the sensing devices are functioning satisfactorily. In a further embodiment, the control circuit is formed of a number of isolated sections, each supplied from a separate energy source.

Title: Code reading method and apparatus
IPC: G11B5/09
Filed: 1969-08-06
Abstract: In a code read-out method and apparatus, a code carrier is in the form of a circular plate of non-magnetic material having, on one surface, clock indicia in the form of concentric, uniformly spaced annular bands of magnetic material and having, on the opposite surface, signal indicia in the form of concentric, selectively spaced annular bands of magnetic material, each opposite a different respective clock indicia. The code carrier is passed along a detection path and between a pair of magnetic pick-up heads which are disposed directly opposite each other, and each of which is associated with a different respective surface of the plate. Both heads are connected in parallel to an AND circuit and to an OR circuit. The OR circuit provides an output pulse responsive to detection of an indicia on either surface of the plate. The AND circuit provides an output pulse responsive only to simultaneous detection of indicia on both surfaces of the plate. Thereby, the output clock pulses are readily discriminated from the output signal pulses. Preferably, the magnetic material is imbedded in annular channels in the plate surfaces.

Title: Frame synchronization system
IPC: H04J3/06
Filed: 1971-07-06
Abstract: A binary information signal having a given bit rate and either one of two different synchronization codes and two local binary synchronization reference signals are applied to a digital comparison circuit, the two output signals indicating a match or mismatch between the successive adjacent bits of the information signal and the associated one of the reference signals. The two output signals are OR-ed and AND-ed with these functions being applied to a common decision circuit having a decision level resulting in a "1" output when the decision level is not exceeded and a "0" output when the decision level is exceeded. Search logic operates on the above AND function, or a separately produced AND function, of the two output signals and cooperates with the output of the decision circuit to achieve synchronization to either of the two synchronization code patterns. The search logic is described as employing the immediate response circuit and technique, the look-ahead technique employing one shift register and the look-ahead technique employing two shift registers.
