Patent ES-364963-A1 (ES)
Title: Dynamic braking of induction motors
IPC: H02P3/22
Filed: 1969-03-18
Abstract: An induction motor M is stopped by actuating a micro-switch to de-energize relay IL and disconnect the motor from the supply. Relay IIL is connected across capacitor Q and rectifier V which are now supplied by the motor moving under its own inertia. Capacitors S, T, V, are thus connected across the stator windings so that the motor is self-excited for braking. As the motor speed decreases, the relay RL becomes insufficiently energized to hold contact Ra, whereby relay IIIL is energized from capacitor Y. This causes the stator windings to be shortcircuited, and the motor is brought to rest. Capacitors X and Z maintain the relays IIL and IIIL energized for a period longer than the stopping-time of the motor. In a modification, two stages of capacitive braking are introduced, and this is followed by D.C. injection braking, Figs. 2 (not shown). In a further embodiment the contactors are replaced by thyristors, Fig. 3 (not shown).

Patent ES-418734-A1 (ES)
Title: Process
IPC: C07C11/02
Filed: 1973-09-13
Abstract: There is described the separation of aliphatically unsaturated hydrocarbons from gaseous mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is present essentially in a solid matrix that is a film membrane or is in contact with a film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The liquid barrier is in contact with a relatively non-volatile, hygroscopic agent that may be in solution in the liquid barrier or composited with the solid matrix, This agent may serve to reduce the loss of water from the liquid barrier which loss may otherwise be excessive. The hygroscopic agent when composited within a hydrophilic film membrane, may serve to increase the permeability of the film and maintain the strength of the film when it is swollen with the aqueous liquid barrier. The metal ions in the liquid barrier may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of the metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.

Patent ES-455332-A1 (ES)
Title: Styrene polymer foam and preparation thereof
IPC: C08J9/14
Filed: 1977-01-25
Abstract: Thermoplastic synthetic resin foam articles are described which, in accordance with machine production, are elongated principally in the longitudinal direction and have a cross sectional dimension of at least 6.35 mm and a cross sectional area of at least 51.6 cm<2>, where the cells have a mean cell size in the range from 0.1 to 1.2 mm. These cells contain at least one low-permeability halogenated blowing agent. The blowing agent remains in the cells during use of the foam articles, for example for insulation purposes, and there is no significant release thereof into the atmosphere. On the one hand, this prevents readily volatile halogenated blowing agents entering the ozone layer around the earth, where they can have a damaging effect, and on the other hand very low thermal conductivity of the foam articles is achieved, significantly lower than that of the corresponding foam articles containing air instead of the low-permeability blowing agents.

Containers which are lying down, two containers stuck together, or containers which have a bent neck portion are rejected.
Patent ES-459830-A1 (ES)
Title: Electronic device for monitoring excess flowing medium demand or consumption
IPC: G01R21/133
Filed: 1977-06-16
Abstract: The device exhibits an electronic up/down counter (1). This is supplied with the pulse repetition rate (I1) corresponding to the consumption and output by the electricity meter (2), on the one hand, and with a reference pulse repetition rate (I2) output by a reference pulse frequency source (4), on the other hand. The up/down counter (1) is incremented by the pulses (I1) coming from the electricity meter (2) and decremented by the pulses (I2) coming from the reference pulse frequency source (4). As soon as one counting capacity is filled up, it is reset to the count zero at the same time, a following overconsumption counting mechanism (7, 8) is incremented by one step. Exceeding of the overconsumption threshold for a short time does not necessarily lead to a recording process. As a result, an electromechanical overconsumption counting mechanism can be used, the count of which does not get lost even when its supply voltage is lost.

Patent ES-463171-A1 (ES)
Title: Contactless control pulse generator for rotary machine timing
IPC: F02B1/04
Filed: 1977-10-13
Abstract: For generating control pulses for timing gasoline engine ignition, a rotor of magnetically conducting material with one or more notches in its edge cooperates with a stator also of magnetically conducting material having the configuration of a shallow U, of which the extremity of one leg presents a broad area to the narrow air gap between it and the edge of the rotor and the other leg presents essentially a knife edge. A magnet is mounted on the former leg and a pick-up device, such as a Hall generator, field plate, inductive winding or a reed switch is provided on the other leg to produce an electric signal in response to changes in magnetic flux. The passage of the notch by the broad area foot of the stator produces at most an insignificant change in flux, whereas passage of the notch by the other stator leg produces a sharp change in flux and hence a control pulse.

Patent ES-473335-A1 (ES)
Title: Starter motor for an internal combustion engine
IPC: F02N11/00
Filed: 1978-09-14
Abstract: A starter motor for an internal combustion engine has an electromagnetic switch (11) and a "tooth against tooth" safety spring (37) to deform to allow the switch core (14) to move into a switch closing position even if the teeth on the starter pinion (10) and the starter ring gear of the engine are coincident rather than meshing as the pinion (10) contacts the starter ring gear. The "tooth against tooth" spring is a leaf-spring (37) serving as a yieldable fulcrum for the yoke, and the moving core (14) of the switch accommodates slidably a contact-bearing rod (15) of the switch which rod also passes slidably through the fixed core (13) of the switch. At its end remote from the contact, the rod (15) engages a yieldable stop (34) which biases the rod towards a "contact closing" position. The fixed core is thus devoid of a contact-closing spring and has a more massive flux path than it would otherwise do.
