Title: Nuclear reactor coolant and cover gas system
IPC: G21D1/02
Filed: 1975-04-28
Abstract: A core cooling system is disclosed for a nuclear reactor of the type utilizing a liquid coolant with a cover gas above free surfaces of the coolant. The disclosed system provides for a large inventory of reactor coolant and a balanced low pressure cover gas arrangement. A flow restricting device disposed within a reactor vessel achieves a pressure of the cover gas in the reactor vessel lower than the pressure of the reactor coolant in the vessel. The low gas pressure is maintained over all free surfaces of the coolant in the cooling system including a coolant reservoir tank. Reactor coolant stored in the reservoir tank allows for the large reactor coolant inventory provided by this invention.

Title: Magnetic bubble devices with controlled temperature characteristics
IPC: H01F10/00
Filed: 1976-08-25
Abstract: The temperature variation of the bubble collapse field of a class of garnet magnetic bubble layer materials is selected by control of octahedral site substitution during layer growth. This permits the growth of layers, whose temperature dependence of critical magnetic properties more closely matches the temperature dependence of available bias magnet materials, resulting in extended operating temperature range and/or wider operating margins (with attendant improvement in manufacturing yield). A preferred substitution species is lutetium, known as a dodecahedral site occupant, for which it has been determined that a significant and controllable octahedral occupancy can be produced by suitable choice of growth conditions.

Title: Navigation system for maneuvering a structure about a submerged object
IPC: F16L1/20
Filed: 1976-09-08
Abstract: The navigation system permits remote maneuvering of a water-borne structure about a stationary object by utilizing dual sonar ranging. The structure can be self-propelled or towed by a surface craft. The transducer portion of the navigation system is mounted on the structure and the system's remaining portion is on the deck of the surface craft. For complete remote navigation, at least three but preferably four transducers are employed for positioning at the four corners of a rectangle. Each transducer is both sound-emitting and sound-receiving. The sonic impulses from each pair of port and starboard transducers are directed downwardly and inwardly. The travel time for each reflected sonic impulse is directly proportional to the slant range between the transducer and the object. The spacing between each pair of port and starboard transducers and the frequency of the emitted sound impulses are selected so that very accurate measurements are obtainable of the position of the object relative to the transducers. If the object is a pipe it is desirably maintained on a visual display in a longitudinal plane of symmetry for the two pairs of transducers. Any appreciable lateral deviation from the desired position is immediately detected and corrective action can be taken by the surface craft to reposition the structure.

Patent ES-485498-A1 (ES)
Title: Aft circuit
IPC: H03J7/02
Filed: 1979-10-29
Abstract: An automatic fine tuning (AFT) circuit is provided which generates an AFT control signal in response to a video intermedate frequency (I.F.) signal. The I.F. signal is supplied to the input of a current source amplifier, which provides current signals of like phase relationship to a discriminator network. The discriminator network is comprised of two tuned circuits, one of which is resonant at a frequency below the desired frequency of the I.F. picture carrier, and the other resonant at a frequency above the desired frequency. The tuned circuits develop voltage variations which vary differentially in magnitude in response to the frequency deviation of the I.F. picture carrier from its desired frequency. The differentially related voltages are detected by two peak detector networks for use as AFT control signals. The current source amplifier and peak detector networks may be conveniently fabricated on a single I.C. chip. The tuned circuits are coupled to the current source amplifier and peak detector networks through two external I.C. terminals.

Patent ES-8103618-A1 (ES)
Title: Pulse shaping circuit
IPC: H03K5/07
Filed: 1980-05-02
Abstract: A pulse shaping and amplifying circuit is formed by connecting a capacitor in series with the primary winding of a pulse transformer, connecting normally open switching means in parallel with the capacitor and primary winding, and connecting this parallel combination through a series inductor to a source of d-c control power, whereby the capacitor accumulates a charge from the control power source and then, during periods when the switching means is closed, discharges through the switching means and the primary winding. During its closed periods the switching means also conducts current from the control power source through the inductor, but when the switching means is opened the current in the inductor is transferred to the capacitor and the primary winding and thereby assists recharging of the capacitor. The pulse transformer is provided with at least one secondary winding which is connected to a load circuit by a full wave rectifier means comprising a first diode poled to conduct load current when capacitor discharge current is flowing in the primary winding and serially interconnected second and third diodes poled to conduct load current when capacitor charging current is flowing in the primary winding. Another capacitor is connected in series with one of the second and third diodes across the load circuit, whereby it ensures continuous load current after the first half cycle of operation of the pulse shaping circuit if the closed periods of the switching means recur at a sufficiently high frequency.

Patent ES-8303120-A1 (ES)
Title: Method of controlling operation of an electrostatic precipitator.
IPC: B03C3/68
Filed: 1981-12-16
Abstract: The invention relates to a method of controlling the DC-voltage in an electrostatic precipitator which is energized by pulses superimposed on the DC-voltage. In order to control the DC-voltage the pulses are turned off periodically and the corona discharge current, resulting from the DC-voltage, is measured and compared with a set value. If the discharge current measured is lower than the set value then the DC-voltage is increased and if the discharge current is higher than the set value then the DC-voltage is decreased. The DC-voltage may be temporarily increased during the time when the corona discharge current is measured or, alteratively the DC-voltage can be arranged to be contuously increased or decreased and the measuring of the corona discharge current can be arranged either to maintain the increase or decrease or to change an increase to a decrease and vice versa.
