Patent DZ-3025-A1 (DZ)
Inventor: MARTINS DIAS SUSETE MARIA
IPC: C02F1/72
Filed: 2000-03-21
Granted: 2004-03-27
Abstract: The present invention concerns a process for the treatment of effluents by means of catalytic oxidation with hydrogen peroxide, using heterogeneous catalysis in the presence of metal pairs with anodic and cathodic characteristics (for instance iron and copper). This process can be applied to the effluents of the food-processing industries (olive oil mills, distilleries, sugar refineries, coffee production, tanneries, etc.). The pre-treated residues can be used as fertilisers or in the production of acetate derivatives. This new process has advantages in economic and environmental terms and allows the self-regeneration of the metals through a process of oxidation/reduction of their ions, which leads to only traces thereof in solution, therefore avoiding the habitual need for a step involving the recovery and/or elimination thereof.

Patent ES-280286-A1 (ES)
Title: Device for orienting and feeding articles to a movable support
IPC: H01J9/24
Filed: 1962-08-25
Abstract: Caps 8 for electric filament lamps are lifted from a container 6 in which they are randomly disposed and are placed in correct orientation on a conveyer 2. A reciprocating member 11 periodically lifts a number of caps 8 into a vibratory conveyer 15. The latter in conjunction with a gate 16 delivers the caps 8 one by one to respective recesses 19 of a rotating member 18. Each cap 8 tends to fall base-downwards into the recess 19 and this action is assisted by the action of an air jet passing from a conduit 43. The caps then pass to a vibratory conveyer 31 and thence via a gate 28 (Fig. 1, not shown), to a respective holder 3 of the conveyer 2. An air jet 52 operates during the latter operation. When a predetermined number of caps have backed up along the conveyer 31 a light from a source 50 is obstructed resulting in stopping the table 18. The member 11 may be replaced by a helical vibratory member.

Patent ES-322940-A1 (ES)
Title: Fluid control valve
IPC: F16K11/07
Filed: 1966-02-11
Abstract: Each valve of a bank of valves has a spool valve 7 slidable in a bore 6 intersected by a pair of exhaust ports 17, working ports 9, 10 feeder ports 14, 15 and an open-centre supply port 11. The feeder ports 14, 15 are in communication through a check valve 16 and the port 14 opens into the supply port 11 upstream of the bore 6 the port 11 has upstream and downstream sections connected to adjacent valves, which sections are in communication when the spool is in the neutral position only in any other position the communication is prevented and fluid is supplied to the required working port from port 14 or 15. The working ports 9, 10 are connected to the rod and head end of a jack 8 and the spool has a " slow " and " fast " lower positions " slow " lowering is effected by passing the fluid from the jack head-end to exhaust via a restricted passage 20 in the spool the passage 20 is removed from the path of the exhaustive fluid during " fast " lowering. " Fast " lowering is prevented by a stop if the jack is heavily laden, the higher exhaust pressure resulting therefrom being sufficient to move a piston 26 within the spool 7 to the right against an adjustable spring causing a cam 32 to urge balls 22 radially to engage shoulder 25 so preventing further right-ward movement of the spool. Inward camming of the balls by the shoulder 25 also provides the operator with an indication by " feel " when he moves the spool into the " fast " lower position, such as when the jack is lightly or moderately loaded. In another form (Fig. 4, not shown), the valve has both " fast " and " slow " raise positions and the stop is operative during either " fast " raise or lower if the jack load is heavy. In the " fast " raise position a regenerative action is provided by using the fluid exhausting from the rod end to augment that supplied by the pump to the head end. The stop device may be connected by external passages to the jack, and the device may operate in the neutral position only of the valve.

Patent ES-364334-A1 (ES)
Title: Fluid compressors and turbofan engines employing same
IPC: F02K3/06
Filed: 1969-03-03
Abstract: A compressor, e.g. in a turbofan engine as shown, comprises a rotor 34 having a row 36 of relatively long blades extending to an outer duct wall 38, and a row 62 of relatively short blades extending to a splitter ring 54. Air discharged at relatively low energy from the inner portion of blade row 36 is guided by vanes 56 into the blade row 62 where it received additional energy. Air discharged at relatively high energy from the remaining portion of the blade row 36 passes through flow straightening vanes 70, struts 72 and a propulsion nozzle 15. Flow straightening vanes 64 are inclined as shown in Fig. 3 with their concave surfaces facing generally towards the inner wall 80, to encourage the air to flow inwardly into inlet 46 of high-pressure compresser rotor 24. The leading edge of nacelle 42 forms a second splitter. During deceleration of the engine, the rotor 24 decelerates more rapidly than the rotor 34 and therefore is incapable of receiving all of the air leaving the vanes 64. However, the excess is readily diverted into nozzle 15 without substantial increase in back pressure and consequent stall at the vanes 64.
