Patent ES-368664-A1 (ES)
Title: Automatic optimal setting of the electrode spacing of electrolytic cells.
IPC: H02H7/00
Filed: 1969-06-21
Abstract: A control arrangement for a large number of electrolytic cells 2 comprises an electronic scanning device 3 connected to the cells through D. C. transformers 4 and feeding a central control unit 1 through an analogue to digital converter 5. The unit 1 takes the form of a digitally-operated data processing device which is programmed to control an order distributer 6 which in turn transmits signals to the electrode setting members 7 for the cells 2, so that the electrode spacing of each cell is maintained at an optimal setting (according to the cell voltage sensed by the transformer 4) or is altered to eliminate short circuit conditions. Members 7 may comprise relay controlled reversible motors and, as shown in Fig.2, selector relays 12 control respective groups of setting gears driven by motors 11 whose direction of rotation is determined by energization of one or other of relays 13, 14. The condition of the relay contacts is monitored by the unit 1 through another electronic scanning device 15, to stop the transmission of setting orders in the event of a relay fault. The distributer 6 may comprise addressable, bi-stable electronic switching stages each associated with a relay 12 and the relay 13 or 14, so that a setting operation lasts for a predetermined time determined by the unit 1. To ensure termination of setting in the event of a fault in the unit 1, the stages associated with relays 13, 14 may be monostable and dependent on pulses from the unit 1 indicative of its condition (correct or faulty). An independent time switch stage 16 also monitors the condition of the unit 1 and, in the event of a fault therein, automatically increases the electrode spacing of all of the cells 2 to prevent short circuits during the inoperative period of the unit 1. The stage 16 may also be used for remote manual control of the electrode settings.

Title: Sealing of foam plastic sheets
IPC: B29C65/00
Filed: 1970-06-17
Abstract: One or more thermoplastic foam films or foam sheets with a density below 250 kg. per cubic meter, preferably below 100 kg. per cubic meter, are sealed by overlapping the films or sheets without a bonding agent therebetween, enclosing the films or sheets at least substantially on all sides in dies 1, 2, 7, 8 adapted to compress them at a temperature above the softening point of the plastics material, foaming again the compressed product at the same temperature by decreasing the pressure, and sealing at a predetermined foam thickness by cooling at least one side. Preferably, the pressure is decreased by increasing the distance between the die sections until a predetermined foam thickness is reached. The pressure applied to the films or sheets enclosed in the dies is at least 2 kg. per square cm. If the films or sheets consist of polystyrene foam having a density of 40 kg. per cubic m., they are sealed at a pressure of 4 kg. per sq. cm. and a temperature of 120-130 C., e.g. 128 C. In another example, two cross-linked polypropylene foam sheets having a density of 70 kg. per cubic m. are sealed in 4 seconds at a pressure of 20 kg. per sq. cm. at a die temperature of 185 C. Other specified foam plastics compositions are polystyrene-rubber compositions, polyvinyl chloride, copolymers of vinyl derivatives, polyethylene and polypropylene and their copolymers and acrylonitrile-butadiene-styrene compositions. A container, Figs. 1 and 2, is made by folding a foam plastics blank 9 about a heated mandrel 1 with the upper flaps 11, 12, 13, 14 folded as shown in Fig. 2. The external planes of the blank are enclosed and compressed by heated die halves 7, 8 and a heated plunger 2. The pressure is reduced and the distance between the parts 2, 7, 8 and the mandrel 1 is increased to allow foaming. Cooling is then effected either by cooling the parts 2, 7, 8 or by removing these parts and shifting the mandrel 1 to another position in which cold or cooled parts 2, 7, 8 are applied to the blank.

Patent ES-412912-A1 (ES)
Title: Closure cap
IPC: B65D51/14
Filed: 1973-03-22
Abstract: A metal cap for closing a container, e.g. a glass container for foodstuffs, of the kind comprising a cap base extending over the container mouth and beyond its outer edge and a separate encircling cap skirt secured to the container by a screw or bayonet connection and engaging over the edge of the cap base the cap base being originally curved inwards, but being forced into an outward curve by the anchoring forces acting on its edge when the skirt is secured over it and subsequently being curved inwards again by reduced pressure formed in the container. Loss of pressure is thus indicated by a return to the outwardly curved condition. The region of the cap base projecting beyond the outer edge of the container mouth has a downwardly widening conical edge portion engaged by a rolled-in bead on the upper end of the cap skirt. The adjacent portion of the cap skirt may be conically tapered, and the conical edge portion of the cap base may terminate in an out-turned stiffening flange. The circle of contact preferably lies slightly below the plane of the container mouth. Good engagement and sealing are thereby obtained as well as reliable inward and outward curving of the cap base.
Patent ES-426416-A1 (ES)
Title: Composite transistor device with over current protection
IPC: H02H7/20
Filed: 1974-05-17
Abstract: The base-emitter junctions of a power transistor and an auxiliary transistor are paralleled. The smaller collector current of the auxiliary transistor can be sampled so as to indirectly sample the larger collector current of the power transistor. When the indirect sampling indicates that the collector current in the power transistor is tending to exceed its rated maximum value, its base and emitter electrodes are clamped. This prevents increase in the base-emitter potential of the power transistor and consequently increase of its collector-to-emitter current.

Patent ES-442605-A1 (ES)
Title: Label applicators
IPC: B65C9/14
Filed: 1975-11-13
Abstract: A label applicator has a rotating head assembly for carrying labels from a hopper for application to articles to be labelled. The labels are held on the head assembly by suction. To load labels from the hopper, the hopper is reciprocated towards a spring loaded suction head of the head assembly, depressing the head thereby connecting suction to it, and then away again. A latch locks the head in a depressed state so that a label is withdrawn from the hopper. The head assembly is driven stepwise to stop temporarily for loading a label on each head. The latch is released allowing the loaded head to spring forward when it has rotated to a desired orientation on the head assembly. The released head presses the label onto the article to be labelled simultaneously disconnecting the suction. For heat activated adhesive labels, a radiant heater, preferably a quartz infra-red tube, is arranged to irradiate labels when loaded on the suction heads.

Patent ES-468296-A1 (ES)
Title: Integrated semiconductor crosspoint arrangement
IPC: H01L21/8224
Filed: 1978-03-28
Abstract: Symmetrical integrated transistors and drive circuitry provide low loss bilateral analog crosspoints for a switching matrix. Each crosspoint comprises a high performance PNP lateral transmission switching transistor and an associated NPN vertical drive transistor formed over a common n-type buried tub in a p-type substrate. Individual crosspoints, including the transmission transistor and the drive circuitry, are isolated by means of frame shaped p-type isolation regions lying outside the buried tub. The collector of the NPN drive transistor and the base of the PNP transmission transistor are ohmically connected by means of the buried tub. Accordingly, although the transmission transistor and the drive transistor are merged in a single isolation region, current drive to the PNP transistor is by means of the NPN transistor as a functionally independent device. The lateral PNP transistor comprises stripe shaped emitter and collector electrodes which are formed in a single step with the isolation region and the electrodes are of equal doping, size, and shape. Pluralities of such emitters and collectors which are respectively interconnected by surface metallizations may be utilized to increase the efficiency and the current carrying capacity of the transmission transistor.
