Patent ES-346860-A1 (ES)
Title: Intake system for internal combustion engines having at least two carburettors
IPC: F02M1/00
Filed: 1967-11-07
Abstract: In an intake system having at least two carburetters 1, 2 supplying individual main ducts 6 and 7, each main duct communicates with a duct 12, 13 leading to a common mixing chamber 14 and a duct 15, 16 leading back from the mixing chamber. A shut-off valve 17, 18, provided in each main duct between the ducts 12, 13 and 15, 16 is adjustable so that at idling and low output of the engine the valve will be closed and the whole fuel-air mixture passed through the mixing chamber and at high engine output the valve will be opened and substantially the whole mixture passed through the main duct. One wall of the mixing chamber 14 forms part of the wall of the exhaust pipe 19 to provide heating for the fuel-air mixture and ribs 20 project into the chamber to promote mixing. The valves 17, 18 are operated by a cam on the spindle of the respective mixture throttle 4 and 5. The spindle (21, Fig. 2, not shown), of the mixture throttle 4 is secured to a lever (22) formed with a cam face (23) which co-operated with a roller (27) on a lever (26) secured to the shut-off valve spindle (25). The throttle spindle (21) is rotatable through an angle before the cam face (23) contacts the roller (27) and then the shut-off valve spindle (25) is rotated more and more relatively to the turning angle of the throttle spindle until the valve and throttle simultaneously reach their fully open positions.
Patent ES-355598-A1 (ES)
Title: Device for winding flexible tubing carrying fluid under pressure
IPC: B66C13/14
Filed: 1968-06-28
Abstract: A device for winding a flexible pipe comprises a drum 10 supporting a flexible pipe 9, a fixed support 11 on which the drum is rotatably mounted, an hydraulic motor 14 coupled to the drum, an hydraulic receiver e.g. a double acting jack for a grab or bucket, fed by the pipe and movable with respect to the support 11, a twoway flow selector 19 between a fluid source 16 and the motor 14, the movement of the selector 19 being dependent on the direction of movement of the receiver relative to the support 11, a first conduit 18 delivering fluid during winding of the pipe, a first calibrated valve 22 in the conduit 18, a second conduit 21 delivering fluid during unwinding of the pipe, and a second valve 23 calibrated at a pressure less than the valve 22 in said conduit 21, the two conduits having a common point 30 located downstream of the valve 22 and upstream of the valve 23. During winding of the pipe, a contact 26 of an electromagnetic circuit is closed and the selector 19 connects the fluid source 16 to the conduit 18, the valve 22 being set to provide a torque on the motor 14 which corresponds to a tangential force at least equal to the weight of the pipe 9. Thus the pipe is wound under constant tension, excess fluid being returned to the source 16 via the valve 23. When the pipe is unwound, the contact 26 is broken and the selector 19 connects the motor 14 to the source 16 via the conduit 29, 21. In this case, the motor 14 is driven by the rotation of the drum 10 due to the pull of the pipe 9 and fluid is fed through the motor, the calibrated valves maintaining the correct pressure of fluid to tension the pipe 9.

Title: Method for controlling tube height by tensile inflation
IPC: B21D53/04
Filed: 1970-05-06
Abstract: In a method of making a tube-in-strip heat exchanger formed from composite strip provided with an internal pattern of stop weld material, a tensile force is applied to the strip 6 whilst the tubular passages are expanded by fluid under pressure. The strip 6 is held by a clamp 20 and pulled by a grip 21 to produce a tensile force of 40-110 p.s.i. whilst water under pressure or air under pressure at 2000-2700 p.s.i. is supplied through a device 22 to expand the passageways. The composite strip is formed by hot-rolling after which it is annealed, cold-rolled and further annealed. Opposite sides of the composite may be of the same or different metals, e.g. Al, Cu. The heat exchanger may have marginal fins (14, 15), (Fig. 4, not shown), formed by slits or fluid-inflated passages.

Title: Echo canceller
IPC: H04B3/23
Filed: 1973-08-09
Abstract: An echo canceller for a long-distance telephone circuit comprising a hybrid whereby a branch network supplied by the signals of the incoming direction of the four-wire path is provided with a number of outputs which correspond to systems having pulse responses which are linearly independent from each other provides output signals which are directed by way of gain elements to an adder whose output signal is subtracted as a simulated echo signal from the signals of the outgoing direction of the four-wire path. Each gain element can be adjusted by the integrated output signal of a multiplying arrangement which multiplies the respective output signal of the branch network with the remaining echo signal which is being weighted with one or several weighting factors in the outgoing direction of the four-wire path. A control arrangement is fed by the output signals of the branch network and the remaining echo signal, the control arrangement controlling the weighting factor or factors in such a way that the weighting factors normally accept the maximum value and are attenuated in case of the occurrence of interfering noise in the outgoing direction of the four-wire path greater the stronger the interfering noise and the better the already achieved setting accuracy of the gain elements, such as for example in the case of the occurrence of speech signals of the near-end subscriber.

Patent ES-471676-A1 (ES)
Title: Installation control valves
IPC: F16K1/22
Filed: 1978-07-13
Abstract: An installation control valve, for example for use in a fire fighting sprinkler installation, comprises a pivotal butterfly valve disc co-operable with a movable stop, which in one position abuts the valve disc to retain the valve closed against pressure forces acting thereon. A retaining mechanism is releasably held to resist stop movement and so prevent valve disc opening but is operable under a predetermined condition to permit stop movement from said one position to a second position. When the stop is in the second position, unequal pressure forces on either side of the valve disc cause same to move thereby opening the valve.
