Patent ES-460534-A1 (ES)
Title: Article presence sensor
IPC: H03K17/955
Filed: 1977-07-08
Abstract: Apparatus for sensing the presence of an article. One end of a very high impedance resistor is held at a fixed voltage. The other end of the resistor is connected to a sensing element. When an article is placed close enough to the sensing element, a form of capacitive coupling to ground is created which causes a minute current flow through the resistor. This causes a small voltage drop across the resistor. The current and voltage difference are presented to a voltage follower which effectively amplifies the current. Sample and hold circuits furnish a signal which indicates the actual voltage level. A minimum level detector measures the voltage level with no article present. This level is compared with the sample and hold signal, and an article present signal is generated if the sample and hold signal is a pre-selected amount greater than the minimum level.

Title: Seat height adjustment mechanism
IPC: B60N2/18
Filed: 1978-02-03
Abstract: A seat height adjustment mechanism comprises a seat base frame mounted on a supporting fixture by means of front and rear sets of levers to enable the vertical height of the front and rear ends of the seat base to be adjusted relative to the fixture.

Filed: 1980-04-22
Abstract: Living plants, in particular coniferous plants, with the exception of Picea, Abies, Tsuga, Larix, Taxus and Cedrus genuses, are preserved in that they are caused to suck up a preservative liquid which is based on glycerine and water in the tolume proportions of 18:82 to 35:65 and contains dyestuffs for replacing the color of the plant parts after the preservation. The dyestuffs are to comprise, apart from a blue and possibly also a red dyestuff, tartrazine (C.I. 19140, E102) in a concentration of from 2-10 g/l of preservative liquid. The blue dyestuff comprises preferably patent blue V (C.I. 42051, E131) in a concentration of from 0.1 to 0.8 g/l and the red dyestuff most preferably of new coccine (C.I. 16255, E124) in a concentration of from 1 to 20 g/l. The relative concentrations between the different dyestuffs are adapted into conformity with the sought-for color of the preserved plant. The preservative liquid may advantageously also contain at least one plant nutrient substance, in particular a water-soluble potassium salt, preferably potassium nitrate in a concentration of from 1 to 15 g/l. The preservation is effected at a temperature of from 15 to 33 DEG C in a current of air at a relative humidity of at most 60%, the preservative liquid preferably being a few degrees centigrade warmer than the current of air.

Patent ES-8304328-A1 (ES)
Title: Television receiver power supply
IPC: H04N3/18
Filed: 1982-04-13
Abstract: The primary winding of a high leakage inductance transformer is coupled to a source of alternating input voltage to develop alternating polarity output voltages across tightly coupled secondary windings, including a high voltage winding of the transformer. Various DC supply voltages, including the ultor voltage, are derived from the secondary winding output voltages. To regulate the secondary winding output voltages, a ferroresonant circuit comprising a capacitor and a saturable reactor is coupled as a load circuit to one of the transformer secondary windings. When the saturable reactor magnetically saturates during each half cycle of the alternating polarity output voltage, a circulating current is generated and flows between the saturable reactor and the capacitor. To enhance the power supply efficiency and reduce the temperature rise within the magnetizable core of the saturable reactor, the parameters of the transformer and ferroresonant load circuit are selected so as to generate a relatively low amplitude circulating current. To improve output voltage regulation when a low amplitude circulating current is developed, a compensating drive winding is provided that is magnetically tightly coupled with the primary winding of the high leakage transformer. The compensating drive winding is coupled in series with the saturable reactor winding across the capacitor and polarized relative to the capacitor coupled transformer secondary so as to oppose the tendency of the output voltage amplitude or half-cycle volt-second area to vary with variations in input voltage amplitude.
