Patent ES-483680-A1 (ES)
Title: Method of growing plants
IPC: A01G9/10
Filed: 1979-08-27
Abstract: Plants are grown in shaped suitable substrates 16 which rest on a support 10. Between the support 10 and the substrates 16 are provided two nets 17, 18. Periodically the roots are sheared either by moving the nets relative to one another, or by the action of a blade or wire 14 moving between the nets. This shearing aids growth since the removal of each root tip results in the growth of several root tips.

Patent ES-8102994-A1 (ES)
Title: Process for removing alkalinity and hardness from water.
IPC: B01J49/00
Filed: 1980-02-15
Abstract: Raw water is fed to a first column containing a weak acid cation exchange resin in hydrogen form where alkalinity causing ions and hardness causing ions to the extent of alkalinity are converted to carbonic acid. The carbonic acid, which hydrolyzes to dissolved carbon dioxide, is stripped from the water in a decarbonation unit by passing air countercurrent to the flow of water through the unit. The water is then fed to a second column containing a weak acid cation exchange resin in sodium form which removes residual hardness causing ions along with neutralization of any mineral acids or residual dissolved carbon dioxide. Both resins are substantially completely regenerated upon exhaustion to provide a process in which the maximum capacities of the resins are utilized, and the process is carried out with a minimum of monitoring and control.

Title: Device for transporting and launching a plurality of projectiles contained within a container.
IPC: B64D1/04
Filed: 1980-05-22
Abstract: The invention concerns a process and apparatus for transporting and dropping a plurality of charges contained in a single container. Within the shell of the container is arranged a plurality of modules, the bodies of which contain a charge, which may particularly be military said modules are extracted one by one, upon command, through the rear of the shell. This extraction can take place only if a general mechanical control element has moved from a position called the "safety" position to a position called the "cocked" position, a movement which can take place only when the means for fastening the container has been released from the lug holding it to the carrier vehicle. The invention is applied particularly to modular bombs having fragmentable modules designed for neutralization of relatively widespread ground targets.

Title: Method of protecting a thyristor switch of a pulse generator.
IPC: H02H7/00
Filed: 1982-05-20
Abstract: Method of protecting a thyristor switch element, of a pulse generator supplying a capacitive load, against damage during sparkovers which occur in the load, the method comprising triggering the thyristor or thyristors (T) in the switch element to conduction if a sparkover occurs in the load (CF) during a period of pulse decay. This can be achieved by starting a timer whenever a pulse starts, the timer running for the duration of the pulse, and detecting the slope of the voltage across the load as a function of time and triggering the thyristor to conduction when the slope of the voltage function exceeds a preset value at a time when the timer is running. Alternatively, for use in an energy conserving pulse generator system, where the pulse current consists of half a period with a current running in one direction and half a period with the current running in the opposite direction, the pulse current can be sensed and the thyristor triggered to conduction if a shift of current direction occurs during a period of pulse decay.

Title: Digital television receiver automatic chroma control system
IPC: H04N9/68
Filed: 1983-03-11
Abstract: The gain of the chroma signal in a digital television receiver is controlled in accordance with the value of a composite gain factor which is an accumulation of gain control factors provided by a user color control, automatic chroma control, and chroma overload. Gain control according to the composite gain factor is realized by a coarse gain block, which increments or decrements the chroma signal gain in increments of six dB, and a fine gain control over a range of six dB or less, in finely controlled increments. In a preferred embodiment, the digital chroma gain system is operated under control of a microprocessor, which receives signals representative of chroma overload, user control settings, and chroma burst amplitude. The microprocessor then calculates the composite chroma signal gain and apportions the gain between the coarse and fine gain control blocks. In the preferred embodiment of the invention, the coarse gain block comprises controlled shift registers for controlling the chroma signal gain over a range of 18 dB in 6 dB increments. The fine gain block comprises an adder and a random access memory (RAM), addressed by the chroma signal, which contains a data table computed by the microprocessor.
