Patent ES-297488-A1 (ES)
Title: Alternating current generator having a phase shifting feedback circuit
IPC: H05B6/04
Filed: 1964-03-11
Abstract: An oscillator comprises a valve amplifier having a resonant output circuit 2, Fig. 1, which is back-coupled to the input of the valve via a four-terminal network 5 comprising first and second shunt reactances 12, 13, respectively, of the same sign, and in which the reactance 12 may be wholly or in part the input reactance of the valve. The network also comprises first and second series reactances 14, 15, respectively, which, with the input to the valve grid, as shown, are both of the opposite sign to the shunt reactances: with the input to the cathode instead, the reactance 15 must be of the same sign as the shunt reactances (Fig. 2, not shown). The reactances 13, 15 may be variable. The use of a capacitor as reactance 12 reduces harmonics. The reactances 13, 14 are made of the same absolute value at the operating frequency and reactance 15 much greater than either: with these conditions, the phase-shift through the network is 180 degrees (or 0 degrees in the alternative cathode drive circuit) and is independent of the input resistance 11 of the valve, so that grid current does not affect the phaseshift of the feedback path and hence the efficiency of the oscillator. Correction for the finite value of the reactance 15 can be made by slight variation of the reactances 13, 14 from exact equality. The reactance 15 may be coupled to the rest of the network 5 via a transformer, the shunt reactance 13 being connected either across the primary or secondary windings, or distributed between the two (Figs. 3, 4, not shown) the connections to one side of the transformer may be reversed, enabling the sign of the reactance 15 to be the opposite to that used in the basic network (Fig. 5, not shown). In an oscillator using a network of this latter type the valve obtains its anode supply over a choke 20, Fig. 6, and feeds via blocking capacitor 27 a tuned circuit 24, 25 in which the load 26 is placed in series with inductor 25. The four terminal network comprises capacitors 12, 13c, 15c and inductor 14, the capacitors 13c, 15c being variable, and the valve is biased by means of grid leak 21. In another embodiment the anode of the valve is grounded and the second series reactance 15, Fig. 7, of the four terminal network comprises an inductor through which the D.C. supply to the cathode is fed. The anode load, coupled over blocking capacitor 27, comprises a network of the type disclosed in Specification 971,315.

Title: Face seal structure
IPC: F15B13/00
Filed: 1969-10-15
Abstract: A device for raising the pressure of a lowpressure first liquid by a high-pressure second liquid, e. g. process liquids from an exchange crystallization sea-water desalination process, comprises a rotor 10, e. g. driven by an electric motor, and a stator 32 with liquid connections 55, 76 and 64, 79 which sequentially register with rotor bores 16, 18 containing ball pistons 28, 30, sealing between the rotor and stator being effected by plates 60, 86 formed with arcuate ports and located by the stator and provided with sealing elements engaging the rotor and stator, the sealing elements defining areas exposed to pressure which are related, as claimed, to provide a biasing force on the plates. Low-pressure liquid is supplied at connection 55 and high pressure liquid at connection 79, connection 76 being connected to atmosphere and connection 64 to a pressure storage means. In the position shown, piston 28 is moved to the left by incoming low-pressure liquid. On rotation of the rotor, when bore 16 communicates with connections 79 and 64, high-pressure liquid from connection 79 moves piston 28 to the right and discharges the liquid at increased pressure through connection 64. Plates 12 and 14 are secured to the rotor and provide the rotor surfaces engaged by the seals on plates 60 and 86. The sealing element 102, Fig. 7, on the rotor side of each plate 60, 86 comprises a thin sheet of high shear strength and low coefficient of friction, e.g. polyamide resin impregnated with graphite, and is bonded to the plate 60, 86 by adhesive. Alternatively, the plate may be made of the same material as, and formed integrally with, the seal element. The element is located by plate ribs 100, 103. The other side of each plate has O-ring seals 110, 114 and 118 around the plate periphery, central aperture 90 and high-pressure port 92, respectively. The seal 118 also encloses parts of the lands between the arcuate ports in the plate so that the hydraulic pressure at port 92 acts over a larger area to produce a small resultant force acting to continuously bias each plate 60, 86 against the rotor even when bores 16 and 18 are traversing the lands between the plate ports.
Patent ES-374499-A1 (ES)
Title: Electric switch with a snap-action system
IPC: H01H5/04
Filed: 1969-12-12
Abstract: A snap action thermostatic switch assembly of the type having a bimetal arm and an omega spring. The assembly has a fixed contact and a pair of resiliently mounted movable contacts on opposite sides of the fixed contact. The movable contacts have lugs and the bimetal arm has an actuating element which engages these lugs to move one contact or the other away from the fixed contact. The bimetal arm has a displacement range so that the actuating element thereof separates from the contact lug of a movable contact that is brought into engagement with the fixed contact. With this construction the tendency of a movable contact to rebound is minimized by reason of the mass associated with a movable contact being reduced the instant the movable contact touches the fixed contact.

Title: Method and furnace for combusting carbonaceous fuel
IPC: F22B31/04
Filed: 1975-12-30
Abstract: During the combustion of carbonaceous fuels at temperatures above 1800 DEG C in the presence of an at least stoichiometric quantity of air, major quantities of nitrogen oxides are formed. In order largely to avoid the formation of nitrogen oxides, the combustion is carried out in two stages, as follows: in the first stage (612), thermal combustion of a carbonaceous fuel (620) is carried out with a less than stoichiometric quantity of air (652). The exit gas from the first phase (612) is mixed with additional air (662) to form a mixture whose adiabatic flame temperature is above the auto-ignition temperature of the mixture. This mixture is burned in the presence of a catalyst (634) at a temperature above the auto-ignition temperature but below a temperature which would lead to a noticeable formation of nitrogen oxides.
