Patent ES-363657-A1 (ES)
Title: D.c. motor control system which compares the motor current with a reference to control the motor speed
IPC: H02P3/12
Filed: 1969-02-14
Abstract: Two pairs of traction motors are supplied through a thyristor which becomes conductive or non-conductive when a current-responsive signal is less or greater than a reference signal. For braking two loop circuits are formed, each containing two armatures and the field windings of the other two motors with a common braking resistor. The thyristor is connected across a portion of the braking resistance and is controlled, as in power operations, to maintain the braking current at a desired average value. A signal current on line 31 is modified by jerk limit and load weight circuits, and is applied to a capacitor 39. The signal representing the motor current is derived from a transistor and is applied across Zener diode 37 and resistor 38. Conductors 40, 41, provide triggering signal to an "on" pulse generator 29 and an "off" pulse generator 28 respectively. The voltage-drop across the diode 37 determines the difference between maximum and minimum valves of the motor current. In the pulse generator 28, capacitors 48, 56, are charged initially, a positive signal at the base of transistor 42 turning-off the transistor 46 whereby capacitor 48 discharges through diode 50. An output pulse on conductor 27 turns-on the transistor 51 for a short period, so causing transistor 55 to turn-off whereby capacitor 56 discharges through diode 50 to provide an output pulse for quenching the main thyristor. The capacitors 48, 56 are recharged when transistor 51 is again turned-off. In the amplifier 29, the transistor 421 is turned-off to produce an output pulse which is applied to the main thyristor and a commulating thyristor.

Patent ES-381979-A1 (ES)
Title: Bobbin segregating and orienting apparatus
IPC: B65H67/06
Filed: 1970-07-17
Abstract: Apparatus for segregating a jumbled mass of bobbins and delivery of the bobbins one at a time in axial orientation. A chain conveyor includes a plurality of buckets for receiving bobbins. These buckets open inwardly and together form the bottom of a hopper which receives the jumbled bobbins. As the conveyor is driven, a bucket receives a bobbin from the hopper and carries the bobbin upwardly along a substantially straight path to a discharge chute at an upper portion of the apparatus. The buckets have a particular cross-sectional configuration so that when they are on the straight upwardly extending path they will retain only one bobbin having a rounded cross-section and within a particular range of diameters varying from an empty bobbin core to a full bobbin. If a second bobbin is picked up by a bucket it will drop from the bucket along the straight path and fall back into the hopper. By varying the inclination of the buckets along the straight portion of the path, the range may be varied. A bobbin in the hopper may tend to align itself with its axis parallel to the direction of movement of the buckets and would thus block the buckets from receiving bobbins having their axes transverse to the path of movement of the buckets. Such a parallel bobbin is flipped over so that it falls back onto the hopper with its axis transverse to the path of movement of the buckets. Bobbins are fed into the hopper responsive to a reduction in weight of the bobbins in the hopper and the hopper is driven intermittently to deliver bobbins one at a time responsive to an external demand.

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. They may be prepared by (4) reacting 1,4-dihydroxyanthraquinone 6- or 7-sulphonic acid with 1 mole of 3,5,5-trimethylcyclohexylamine and 1 mole of an amine or by aminating a l-halogeno-4-(3,5,5-trimethyl)- anilino - 6 - (or 7) anthraquinone sulphonic acid.
