Patent ES-365959-A1 (ES)
Title: Apparatus for continuous thermal treatment of pourable granules
IPC: B65D88/64
Filed: 1969-04-12
Abstract: Apparatus for the continuous thermal treatment of pourable granular material comprises at least one, e.g. as shown, two, treatment zones 3 delimited at the bottom by fittings 11 and laterally by vertical walls 2 and a flow stabilization zone 4 between the lowest fittings and a discharge zone having two parallel walls and two converging walls 6, the height of the stabilization zone 4 being greater than the product of its width (measured transverse to discharge slot 7) and the tangent of the slope angle of the material, and the angle between walls 6 being smaller than 0À8 times the difference between 180 degrees and twice the slope angle of the material. A substantially "plug" flow of material through the apparatus is achieved as long as the width of the treatment zone is less than 1500 mm. Fittings 11 are gas inlets or heating and cooling elements. The ratio of the width of the discharge slot 7 and the width of the treatment zones 3 is preferably less than 0À1 in order to dam the flow of material for control of residence time. A discharge roller 8 adjusts the quantity of material discharged. For drying polyethylene terephthalate chips a lock-chamber bunker 13 is provided to prevent premature exposure to the atmosphere. The apparatus may comprise several arrangements as in Fig. 1 disposed side by side with a common feed pipe 1 and a common discharge funnel 14 (Fig. 5, not shown). The common interior walls may be omitted (Fig. 6, not shown) but in this case the treatment zones lying above each of the several discharge zones are considered separately for selection of dimensions.
Patent ES-367452-A1 (ES)
Title: Color killer and acc circuits
IPC: H04N9/71
Filed: 1969-04-20
Abstract: In a colour television receiver a common automatic chroma control and colour killer circuit comprises an amplifier circuit, coupled to the receiver's burst amplitude detector, which operates in two modes i.e. in the ACC mode in which the gain of the receiver's chrominance amplifier is controlled when the amplitude of the burst signal is above a certain level, and in the colour killer mode in which the chrominance amplifier is rendered inoperative when the burst amplitude is below this level. In a first embodiment, Fig. 1, the base of transistor 50 is coupled to the output terminal of the burst amplitude detector. In operation for a first range of burst detector output voltages (zero or low amplitude bursts), the base-collector junction of transistor 51 remains reverse biased, and transistors 50, 51 provide a high gain twostage D.C. amplifier for kill/unkill control of the bandpass amplifier 23. When the burst amplitude rises sufficiently to forward bias the base collector junction of transistor 51, transistor action is lost in transistor 51 with a consequent reduction in gain at the D.C. amplifier for killer control purposes. For the range of detector output voltage above that which produces forward biasing of the base-collector junction of transistor 51, the voltage at the collector of transistor 51 directly follows (without polarity inversion) the changes at the collector of transistor 50. These followed changes are applied to the chrominance amplifier 22 to adjust its gain for automatic chroma control purposes. Increase in burst amplitude produces a gain reduction in the amplifier 22. In a second embodiment, Fig. 3, in which independent ACC threshold adjustment is possible according to the magnitude of resistors 66 and 67. Further, the level at which the mode shift takes place is determined independently of threshold determination for initiation of ACC action. This level is determined by voltage divider 64, 68 which biases the cathode of diode 63, the mode shift taking place when the burst detector output level rises sufficiently to forward bias the diode 63. The bursts are eliminated from the demodulator channel by gating the bandpass amplifier 23 with deflection pulses Diode 63 may be replaced by a transistor (Fig. 4, not shown).

Patent ES-383303-A1 (ES)
Title: Apparatus for regulating fluid flow through plastic tubing
IPC: A61M39/28
Filed: 1970-09-01
Abstract: The rate of flow of a fluid through plastic tubing is varied by clamping a portion of a circumferential section of the tube wall with sufficient force to fully close that part of the passage between the clamped wall portions, permitting fluid flow only through the resulting, remaining open cross-sectional area. Cold flow of the plastic material of the clamped portion of the tubing wall, such as might otherwise effect a change in the remaining cross-sectional flow area, is prevented or minimized by rigidly confining the clamped section. To adjustably vary the flow rate, the operative, passage-defining wall section of the tubing is varied by uniformly varying the ratio of the section of clamped tubing, and the remaining, operative wall portion of the tubing, or by deforming the operative wall portion.

When the anthraquinone starting material bears a 1-aralkylamino- or 1 -cyclohexylamino group this may be acylated prior to condensation with 3,5,5-trimethylcyclohexylamine and subsequently hydrolysed. They may be prepared by (2) reacting a 1- halogeno - 4 - (3,5,5 - trimethyl) - anilinoanthraquinone with an amine and then, if the amine contains no SO 3 H . group, sulphonating the product with sulphur trioxide or an agentyielding sulphur trioxide. They may be prepared by (3) reacting a l-amino-4-(3,5,5-trimethyl)-anilino anthraquinone with a halogeno aliphatic or aromatic compound or with benzyl alcohol, or alternatively with an xunsaturated aliphatic carboxylic acid or a halogenoacetic acid and then with an amine to form the acid amide in presence of an inorganic acid halide, the products then being reacted with sulphur trioxide or an agent yielding sulphur trioxide.

Filed: 1975-01-09
Abstract: A method of insulating an electrical conductor by applying thereto a coating of a polyesterimide resin which can be hardened through its free OH groups from a resin melt at above 100 DEG C., wherein the resin used is solvent-free and has been prepared by esterification or ester-exchange of starting materials for the polyesterimide in the presence of an excess of one or more short-chain diols and subsequent removal of the diol or diols in such a way that the condensation is only effected to an extent such that the Durrans softening point of the unhardened resin is not above 150 DEG C. (preferably not above 100 DEG C.) and the viscosity of the molten resin at 180 DEG C. is not above 5000 (preferably not above 1000) mPa s (cP). This process avoids the disadvantages encountered when a solvent is present in the insulating bath.
