Patent ES-462433-A1 (ES)
Title: Fuel injection nozzle * unit
IPC: F02M61/10
Filed: 1977-09-16
Abstract: The valve needle upwards movement is retarded by means of a weight in order to limit the fuel volume injected. The weight (27) is located in an additional chamber (28) in the injector housing (10). A push rod (29) is fitted between the weight and the needle valve stop plate and surrounded by a return spring. The needle valve causes the weight to be displaced on the lift stroke by acting on the push rod. The return spring returns the needle valve to its seat (19) independently to the weight. The weight is returned by its on spring (30) to restore contact with the push rod. A piston could be employed instead of the weight to act as a shock absorber. A restricted passage leading to a drainage is provided above the piston.

Title: A procedure and its corresponding device for treating living organisms with negative ions.
IPC: A61N/
Filed: 1978-11-08
Abstract: In accordance with the invention, two methods of treatment are combined, making a subject submitted to a unidirectional electrostatic field breathe air charged with negative ions. This unidirectional electrostatic field is created between a plate with a negative applied potential, covered with points directed towards the head of the subject and a plate with a positive applied potential in contact with the subject's body. Unexpectedly, the unidirectional electrostatic field very clearly accelerates and reinforces the effects of the negative ion treatment. For example, by this means it has been possible to eliminate hard cholesterol artificially induced in a guinea pig.

Patent ES-8407602-A1 (ES)
Title: Control device, in particular for program switches
IPC: H01H43/10
Filed: 1983-07-14
Abstract: The control device, in particular for program switches in electrical domestic appliances, has cams (1, 2) which control a multiplicity of contacts (1a, 2a). These cams can be turned by an electric motor (M) via a reduction gear. Part of this reduction gear comprises a satellite gear wheel (9) which is mounted in such a way that it can oscillate on an eccentric (10) and is in engagement with a planetary gear wheel (15) which for its part is seated firmly on an output gear wheel (14). This output gear wheel consequently turns at a non-constant rate. The splining of the output gear wheel (14) and of the cams (1, 2) is configured in such a way that, during each advancing step of the cams, they exhibit a rotational speed which successively runs through a first phase with a speed which is initially rapid and then slowed to zero, thereupon a second phase with zero speed and finally a third phase with a speed which initially grows and increases rapidly from zero. During the first and third phases, of about 0.2 seconds duration in each case, the contacts are actuated in two groups, to be precise during advancements of two half-steps of 3 DEG each at a time.
Patent ES-8502290-A1 (ES)
Title: System and method for eliminating short circuit current paths in photovoltaic devices.
IPC: H01L31/04
Filed: 1983-10-20
Abstract: Systems and methods for detecting and eliminating short circuit current paths through photovoltaic devices of the type including at least one semiconductor region overlying a substrate and a layer of conductive light transmissive material overlying the at least one semiconductor region are disclosed. The short circuit current paths which are eliminated extend through the at least one semiconductor region from the substrate to the layer of conductive light transmissive material. The resistivity of the short circuit current path is increased substantially at the interface between the conductive light transmissive material and the semiconductor region by isolating electrically the conductive light transmissive material from the short circuit current path. The isolation can be provided by removing the transparent conductive material from electrical contact or connection with the short circuit current path. The isolation also can be provided by depositing a body of insulating material onto the semiconductor region over an area including a short circuit current path prior to the deposition of the conductive light transmissive material. Further, the short circuit current path can be detected and located by applying a voltage to discrete areas of the device through a conductive solution which path then can be eliminated as described above.
