Patent ES-475212-A1 (ES)
Title: Engine systems
IPC: F02D21/08
Filed: 1978-11-17
Abstract: An engine system includes a valve operable to permit exhaust gas to flow from the exhaust manifold to the air inlet manifold of an engine for the purpose of reducing the noxious gas content of the exhaust. The setting of the valve is dependent upon the amount of fuel supplied to the engine by the pump. A hydraulic signal is generated and this is derived from a supply pump by way of a fixed orifice this pressure being applied to a control valve which regulates the pressure applied to an actuator including a spring loaded piston. A throttle which controls the amount of fuel delivered by the injection pump also forms a further adjustable orifice downstream of the orifice whereby the pressure downstream of the orifice is dependent upon the amount of fuel supplied to the engine.

Title: Method for preparing chlorine by electrolysis of hydrochloric acid, and electrolytic cell therefor.
IPC: C25B9/19
Filed: 1979-04-10
Abstract: In the production of chlorine and hydrogen from hydrochloric acid by electrolysis in an electrolysis cell comprising a plurality of vertically arranged bipolar electrodes, a diaphragm arranged between each two electrodes to divide the electrolysis chambers formed between them into an anolyte chamber and a catholyte chamber, and outlet and inlet devices for the electrolyte, the improvement which comprises electrolyzing the hydrochloric acid in at least two successive stages, and degassing the hydrochloric acid. Advantageously the hydrochloric acid moves from bottom to top, first through an upper stage and then through a lower stage. As a result less electrode surface is needed, a higher current density and/or voltage is possible so existing apparatus can be modified to connect more bipolar electrodes in series.
Patent ES-8101145-A1 (ES)
Title: Weft thread control device for a weaving loom with removal of the weft thread from a supply spool beside the loom
IPC: D03D47/34
Filed: 1979-08-21
Abstract: In a loom having a weft thread supply spool at each side thereof and a shuttle whereby thread from each spool is alternately carried across the shed as a U-shaped loop, improved thread guide elements, one on each end of the batten, are actuated in consequence of movement of the batten through each of its reversal positions, at one of which the batten engages the last-laid weft thread to beat up the same and at the other of which the batten begins its return for another beating-up while the shuttle moves through the shed. Each thread guide element comprises a member mounted on the batten for bodily movement therewith and for rocking movement relative thereto. Each such member rocks between a first position wherein a thread eye thereon is located to dispose weft thread extending from its adjacent spool across the shuttle path and a second position wherein the thread eye holds the thread clear of that path. Each member is rocked to its first position upon movement of the batten through its said one reversal position and to its second position upon movement of the batten through its said other reversal position. Rocking is imparted either by the inertia of a weight on the member, due to acceleration and deceleration of the batten incident to reversal of its motion, or by a friction or magnetic retarding device connected between the member and the loom frame.

Title: Machine tool control.
IPC: B23Q15/00
Filed: 1984-12-10
Abstract: A control system is provided for allowing complex shapes to be machined on a workpiece at high speed. The control system is computer (13) controlled and receives workpiece profile data which are converted into a succession of tool position signals during machining. Not all the digital signals are calculated at one time, a number of future digital signals are calculated during a succession of time intervals. In each time interval, a tool position signal is outputted which is of a constant amplitude corresponding to the required tool position and which is fed to a signal processor (19) where it is converted into a continuous signal which so changes progressively that at successive time intervals, equal to the time intervals of the tool position signals, the amplitude of the continuous signal is related to the successive values of the tool position signals. This continuous signal is fed to a closed-loop control system (22) which controls the movement of the tool holder in accordance with the continuous signal. The tool holder is of a type having a bandwidth sufficient to allow the required movements at the required speed. The control system has proportional and differential feedback (24, 25).
