Title: Process for the production of aluminium
IPC: C22B5/10
Filed: 1977-05-26
Abstract: In a process for the production of aluminium a molten alumina slag, containing combined carbon is circulated through one or more alternately arranged relatively low temperature zones where carbon is added to increase the combined carbon content of the slag by reaction with the alumina slag and high temperature zones where aluminium metal is released by reaction of aluminium carbide and alumina in the slag with consequent depletion of the combined carbon content. Alumina is supplied to the slag at one or more locations. The energy to drive the reactions is preferably supplied by resistance heating of the slag particularly in transit from a low temperature zone to a high temperature zone although usually additional energy is supplied to the slag in the return from a high temperature zone to the next low temperature zone.

Title: Material layer volume determination
IPC: A61B5/145
Filed: 1977-07-22
Abstract: A technique for generally determining the volume of a layer of a constituent material in a centrifugally separated mixture of material. A centrifuge tube is used to hold the material mixture and an appropriately shaped body is disposed in the tube in the zone occupied by the constituent material whose volume is to be measured. The body reduces the available volume within the tube which may be occupied by the constituent material, and thus expands the axial extent of the constituent material to make visual measurement of the constituent material more accurate.

Patent ES-8102288-A1 (ES)
Title: Compressed air servo motor - has inlet and exhaust chambers separated by piston and pressurised prior to use
IPC: B60T13/24
Filed: 1980-06-20
Abstract: The compressed air "suspended" servo motor has an air inlet chamber and an exhaust chamber sepd. by a piston. A high air pressure is maintained in both chambers when the servo motor is in its "ready for use" state. To operate the servo motor the pressure in the exhaust chamber is reduced relative to the inlet chamber to create a pressure differential across the piston. The pressure differential is controlled by a valve located in a piston passageway interconnecting the two chambers and which has an annular plunger operated by movement of an input rod to shut off the passageway. The plunger reacts against the input rod and has oppositely directed areas exposed to the exhaust chamber pressure to effect a balance on the plunger and to limit its nett reaction against the rod (18).
Patent ES-8200494-A1 (ES)
Title: Method and apparatus to prevent tampering with the price indicated by the luminous display of an electronic taximeter and taximeter provided with such an apparatus.
IPC: G07B13/02
Filed: 1980-10-10
Abstract: This anti-fraud system includes a process and devices for avoiding fraud on the price indicated by an electronic taximeter. The taximeter apparatus, which includes a luminous display unit and a computing unit, is supplied with d.c. voltage V by the vehicle battery. One particular fraud, made more difficult by this system, involves voluntary cut-off of the voltage supply to the meter. To execute this fraudulent maneuver the cabdriver firstly starts the meter, and records a price on the fare meter, with no passenger in the taxi. Secondly, before a customer is picked up, the operator cuts off the current supply to the meter, which extinguishes the fare display. Thus, as the customer enters the cab, it is not apparent that the meter has already been run-up to a non-zero value. To preclude this maneuver, the anti-fraud system has a first comparator which compares the voltage V with a reference voltage Vr and emits a constant voltage Vc if V<Vr and a zero voltage if V>Vr. Another comparison device compares the duration during which V remains lower than Vr with a reference time period duration. The computing unit and the display unit are returned to zero each time the reference time period duration is exceeded.

Title: Method and apparatus for pumping concrete to form structure at elevated heights.
IPC: E04G21/04
Filed: 1982-07-01
Abstract: A method and apparatus is disclosed for continuously pumping flowable concrete mix to elevated heights for introduction into forms used in the fabrication of annular structures such as concrete hyperbolic cooling towers. A tower crane is erected in the center of the circle for the hyperbolic structure and concrete conveying piping is provided for raising mix to a lateral conduit carried by a secondary boom suspended from the swingable overhead jib of the crane. A pumping unit at ground level forces concrete mix up the vertical piping on the tower and then through the boom supported conduit for delivery into the form structure. The jib and thereby the boom suspended therefrom are swingable through an arc of 180 DEG in one direction to cover one half of the form structure and then the jib and boom may be swung in the opposite direction through the remaining 180 DEG arc for introduction of mix into the form structure. The tower crane is of the type having a climbing cage permitting lifting of additional mast units to the top of the stack thereof using the jib as a lifting medium to increase the height of the crane. Corresponding pipe sections on the tower mast units allow delivery of concrete mix to increasingly higher elevations as fabrication of the hyperbolic structure progresses. The length of the secondary boom and thereby the laterally extending conduit supported thereby may be increased or decreased as necessary to accommodate the changing diameter of the hyperbolic concrete shell during construction.
