Title: Process for the oxidizing dehydrogenation of isobutyric acid to methacrylic acid.
IPC: B01J27/18
Filed: 1981-06-13
Abstract: Isobutyric acid is oxidatively dehydrogenated to methacrylic acid by passing a gaseous mixture of isobutyric acid, oxygen, nitrogen and optionally water vapor at temperatures of 300 DEG -450 DEG C. and pressures of 0.5 to 5 bar over a catalyst comprising molybdenum oxide, which also contains vanadium, phosphorous and a metal selected from the group consisting of alkali metals, alkaline earth metals, zinc, silver, aluminum, titanium, lead, manganese, iron, cobalt, nickel and tin, preferably precipitated on a solid silica support and calcined at 200 DEG to 400 DEG C. At conversion levels of 80 to 100% of the isobutyric acid used, a methacrylic acid selectivity of 60 to 74% is attained.
Patent ES-8204382-A1 (ES)
Title: Linear drive unit for vibratory conveyor
IPC: B65G27/24
Filed: 1981-07-17
Abstract: A vibratory conveyor has a continuous trough that extends over one or more linear drive units. Each drive unit has an elongated base that extends longitudinally of the conveyor. The base is resiliently mounted to a fixed support. A trough support is disposed parallel to the base. A driver is arranged to move the trough support longitudinally of the conveyor and relative to the base. A plurality of leaf springs extend in an at rest position generally perpendicular to the direction of linear drive, longitudinally of the conveyor. These leaf springs interconnect the base and the trough support at longitudinally spaced locations. The base and the trough support are disposed laterally of each other in a horizontal plane. Preferably, the leaf springs are mounted for pivotal movement about axes extending laterally of the conveyor between the base and the trough support. Such movement adjusts the transverse angle of inclination between one side of the leaf spring and a vertical line. This adjustment can be made without changing the direction in which the leaf springs extend in an at rest position between the base and the trough support, and the adjustment provides a desired vibration angle for the trough. The angular difference between the transverse angles of inclination at the sides of the various leaf springs provides for rotational motion of the trough support relative to the base. This motion compensates for rotational motion of the drive unit on its fixed support due to inertia forces.

Patent ES-8401699-A1 (ES)
Title: Television display system with reduced line-scan artifacts
IPC: H04N5/44
Filed: 1982-09-01
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
Patent ES-8401527-A1 (ES)
Title: An improved method for the production of nucleosides.
IPC: C12R1/13
Filed: 1982-11-26
Abstract: In a fermentation procedure for the production of nucleosides i.e. inosine and/or guanosine using an adenine-requiring microorganism, the fermentation is carried out by allowing a source of adenine to be present in the medium in an excess amount over the amount of adenine that would be conductive to a maximum yield of inosine and/or guanosine in aerobic culture using ordinary air, and cultivating the microorganism while an oxygen-rich gas is bubbled into the medium. Thus, inosine and/or guanosine are accumulated in high yield in the fermentation broth.

Title: Propeller driving displacement type ship
IPC: B63H5/08
Filed: 1983-02-04
Abstract: In order to increase the efficiency of the propeller and hence of the propulsion, the diameter of the propeller (5) arranged at the stern is increased to at least 1.2 or better still 1.5 times the draught at the stern of the vessel under ballast, so that in operation the propeller projects out below the keel line (3) of the ship. So that the ship can travel in harbours, harbour entrances, canals or similar waterways with limited depth, the propeller (5) is brought into an inoperative position, in which no part of the propeller projects beyond the keel line (3) of the vessel, and locked in this position. The ship is then preferably propelled by an auxiliary propulsion, for example a rotating thrustor (8) and also controlled with the aid of this.

Patent ES-8507727-A1 (ES)
Title: Load break switch.
IPC: H01H33/02
Filed: 1984-04-11
Abstract: A single-phase ground enclosed load break switch (205) for distribution voltages has a hermetically sealed cylindrical metal housing (210) of from 2 to 6 inches diameter which contains an insulating gas under pressure. The switch has a movable contact assembly (219) to contact a pair of opposed stationary coaxial conductors (224, 226) within the housing. Movement of the contact assembly (219) along one conductor (224) breaks the connection with the other conductor (226) and simultaneously reduces the sliding contact force on the first conductor (224). The switch has conductive bands (350, 352) coaxially positioned near the housing (210) around the conductors for low voltage measurements monitoring conductor energization and contact position. A rocking bellows (266) at the fulcrum of a crank actuator (264) provides a compact hermetic seal for the actuator without excessive strain of the bellows. A safety interlock with a visual indicator (318) locks the contact assembly in case of a loss of pressure. Excessive pressure in the switch (205) causes the bellows (266) to be punctured with consequent locking of the contact assembly. The switch (205) is small enough to be mounted directly on a transformer or placed into a cable, without the need for a separate enclosure.

Patent ES-8600504-A1 (ES)
Title: Trigger mechanism for an automatic gun.
IPC: F41A7/00
Filed: 1984-04-27
Abstract: The firing mechanism for an automatic firing weapon comprises a catch pawl or detent by means of which a to-and-fro moving weapon breechblock can be retained in its rear or rearmost position. To prevent damage to the breechblock or the catch pawl it is necessary, upon impact of the breechblock against the catch pawl, for such catch pawl to have been completely pivoted into the path of travel of the breechblock. The release of the catch pawl, which can be pivoted by the action of a spring into the path of travel of the breechblock, is accomplished by a feeler lever. This feeler lever fixedly retains the catch pawl in its breechblock release position by means of a firing or trigger lever. The feeler lever is retained, on the one hand, by a control or cam surface of the breechblock and, on the other hand, by a stop lever in its locking position in which it holds the firing lever in a position preventing the catch pawl from engaging with the breechblock. The stop lever can be pivoted out of its locking position for the feeler lever by a release lever which can be actuated in conjunction with the firing lever.

Title: Sheet metal spacer for friction clutch
IPC: F16D69/00
Filed: 1984-07-27
Abstract: Friction couplings, especially for motorized vehicles, with a coupling carrier disc which can be secured to the crankshaft of an engine, an axially movable pressure plate, a leaf spring provided between the latter and the coupling carrier disc and which is supported, via radially outer zones, against the coupling carrier disc and which works on the pressure plate via zones which are radially located further inwards, in which, between this latter pressure plate and the coupling carrier disc, provision is made for elements for the transfer of the overturning (turning) moment, and with a pressure counterplate which, via spacer elements, may be held axially and firmly in rotation against the coupling carrier disc and with a coupling disc located between the aforesaid disc and the pressure counterplate. The aim of the present invention was to make these frictional couplings cheaper, to make them smaller or, also under given spatial conditions, to increase the diameter of the friction and thereby the work capacity, and, moreover, the object was to improve functioning and to lengthen effective duration. This is achieved in accordance with the present invention in that the spacer element is configured as a sheet moulding and in that said piece opens to the counterpressure plate on that side which is remote from the engine.
