Patent ES-427121-A1 (ES)
Title: Fuel injection system
IPC: F02M69/14
Filed: 1974-06-08
Abstract: A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.

Title: Circuit arrangement for tuning and range or band switching of an RF resonant circuit
IPC: H04N5/44
Filed: 1975-03-14
Abstract: A television tuner features a switching voltage generator that resets the voltage across the varicap tuning diodes to about zero voltage when a new tuning range is switched on. This allows the full steepness of the capacitance-voltage characteristics of the diodes to be used in each range. This in turn allows more ranges to be tuned and reduces the effects of stray capacitances.

Patent ES-444257-A1 (ES)
Title: Fuel rod pressurization
IPC: G21C3/02
Filed: 1976-01-13
Abstract: A method and system for fuel rod pressurization and for verifying when pressurization of a fuel rod containing nuclear fuel has taken place. One end of the loaded fuel rod is inserted into a pressure chamber in sealed relation thereto, whereupon the chamber is evacuated to remove the air present. Then the chamber is pressurized with an inert gas. The fuel rod then is drilled to provide an opening in the end of the fuel rod in the chamber, whereupon the rod is pressurized with the inert gas present in the chamber. Acoustic transducers are attached to the fuel rod at predetermined locations externally of the chamber for monitoring any noise which occurs during the pressurization process, which is transmitted through the metal walls of the rod to the transducers. The transducers generate electrical signals which are proportional to the amplitude of the noise sensed and by observing the signals a calibration of the activity going on can be maintained. A pressure transducer is connected with the pressure chamber for monitoring the status of the pressure in the chamber and providing an output signal which is proportional thereto. The acoustic and pressure signals are processed through appropriate electronic circuitry and recorded in analog and/or digital fashion for providing a comparative indication as to the status of when the necessary steps and activities for pressurization of the fuel rod have been accomplished.

Title: Gas seal and silencer for use on tuyere body
IPC: F27D99/00
Filed: 1976-04-21
Abstract: A gas seal and silencer is provided for attachment to a tuyere body to minimize the gas volume and pressure loss during the insertion of a punch bar through a tuyere valve closing the tuyere and so reduce the noise created by the blast of gas leaking out during opening of the tuyere valve. The gas seal and silencer comprises a housing adapted to be secured to the tuyere body with its longitudinal axis substantially in alignment with the longitudinal axis of the tuyere, and closure means mounted within the housing for forming a seal about the punch bar when inserted in the housing. Such closure means may consist of a plurality of closure members mounted for movement toward and away from the punch bar and include means for forcing the closure members against the periphery of the punch bar so as to form a seal between the closure members and the punch bar when the punch bar is inserted in the housing. Such closure members may consist of a plurality of jaws mounted within such housing for radial movement toward and away from the longitudinal axis of the housing and having the ends thereof adapted to contact the punch bar shaped so as to substantially match the periphery of the punch bar. Means are provided for guiding such jaws in their radial movement toward and away from the longitudinal axis of the housing. The ends of the jaws adapted to contact the punch bar are rounded so as to permit the entrance of the punch bar through the jaws even if the punch bar is slightly out of alignment with respect to the longitudinal axis of the housing during insertion of the punch bar through the housing.
Patent ES-448045-A1 (ES)
Title: Fuel control valve
IPC: F02M37/00
Filed: 1976-05-18
Abstract: The disclosure illustrates an anti-tampering fuel control valve for a fuel system providing fuel at a regulated pressure to a series of unit injectors on a diesel engine. The injectors are cam actuated to inject fuel quantities related to the pressure of the fuel supplied to them. The control valve bypasses fuel from the output of the fuel system to a low pressure region when the pressure exceeds a first given level because of fuel system tampering. Orifices in the bypass flow path cause the fuel pressure to follow a schedule generally similar to the normal system pressure schedule but at lower levels. Bypass flow is continued until the fuel system pressure drops to a lower pressure than the pressure at which bypass flow begins.

Title: Method for the control of coccidiosis in poultry
IPC: A61K35/68
Filed: 1978-11-14
Abstract: Effective immunity against coccidiosis can be imparted to poultry if the birds are reared on a regular diet containing added viable sporulated coccidia oocysts at a level sufficient only to induce sub-clinical infection. Preferably the oocyst-containing diet is presented to the birds as soon as they are able to ingest solid food, and contains from 10 to 10,000 oocysts per kg of nutrient feed material. The simultaneous administration of an anti-coccidial drug at a curative level can help to control the immunity-producing infection. The oocyst-containing feedstuff of the invention can be prepared using solid free-flowing pre-mixes or aqueous concentrates, containing appropriate numbers of oocysts together with edible thickening agents. The oocysts can be protected against loss of viability through dehydration by being encapsulated. Growth of the immunized birds is sustained even when they are exposed to a severe oocyst challenge sufficient to induce serious infection in unimmunized birds.

Patent ES-479557-A1 (ES)
Title: Control systems for electric generators
IPC: H02P9/30
Filed: 1979-04-11
Abstract: The excitation winding of an alternator is energized through a silicon controlled rectifier (SCR) from the output of the alternator. The SCR is bypassed by a constant current network to allow the alternator to start up even with no excitation current, when the alternator output voltage is due to residual magnetism alone, this network can pass a current into the excitation winding, and build the current up gradually to a value above the latching current of the SCR. When this has happened, the SCR can latch on after being fired, and takes over control of the excitation current. Because the network is a constant-current network rather than a purely resistive network, it can be designed to pass sufficient current at low alternator output voltages, without having to dissipate excessive power at higher output voltages. Also, when the output voltage is at its normal operating value, the constant-current network is rendered non-conductive, to avoid the excessive power dissipation which might occur at full voltage. A protective circuit is also included, which is tripped if the voltage on the excitation winding should become excessive as the result of an overload. The tripping takes the form of the turning-on of a programmable unijunction transistor (PUT), which remains on, drawing current from a smoothed supply taken from the alternator output, until the alternator speed is reduced to a very low value. At this low speed, the constant-current network cannot pass sufficient current to allow the alternator output voltage to build up, so that the output voltage does not suddenly increase when the PUT turns off.
