Patent ES-8307559-A1 (ES)
Title: Alloy for antifriction bearing layer and process of forming an antifriction layer on steel supporting strip
IPC: B22F7/00
Filed: 1981-09-22
Abstract: The properties of copper-tin-lead alloys are improved with respect to mechanical resistance and resistance to corrosion by the incorporation therein, in specific proportions of nickel.

Patent ES-8305042-A1 (ES)
Title: A method of creating an expression plasmid.
IPC: C12Q1/68
Filed: 1982-02-26
Abstract: Novel plasmidic expression vehicles and methods of using them in the production of useful polypeptides by recombinant bacteria are described. The plasmids employ a tryptophan promoter-operator system from which the attenuator region ordinarily present has been deleted. Bacteria containing the plasmids can accordingly be repressed by the addition of tryptophan against expression of desired polypeptides coded for by inserted genes while they are grown to levels suitable for industrial-scale production. Additive tryptophan may then be withdrawn, essentially derepressing the pathway and permitting efficient production of the desired product in high yield.
Patent ES-8303547-A1 (ES)
Title: High-porosity heat-compacted nickel powder electrode for alkaline water electrolysers.
IPC: C25B11/06
Filed: 1982-03-10
Abstract: The invention concerns a highly porous electrode of special construction and hot-pressed or sintered from nickel powder with the addition of a catalyst and a method for its manufacture. The electrode is characterized by catalytic promotion and long term stabilization by means of an addition of Ti and/or the formation of a surface layer of a stable mixed Ni-Ti oxide so that, when it is used for the electrolysis of water in alkaline electrolytes, the production of the gases of electrolysis takes place with the lowest possible polarization even at high current densities and that it retains its catalytic properties even at high temperatures of the electrolyte or during long times of operation. Because of its favorable properties, the use of the electrode is not limited to water electrolysis technology but is also possible in other technical fields of application such as, for example, the electrolysis of alkali chlorides or the hardening of fats. The electrode can be used both as an anode and a cathode.

Title: Method and apparatus for sealing cut sheet material
IPC: B26D7/06
Filed: 1983-03-24
Abstract: An automatically controlled cutting machine includes a conveyor table having an endless conveyor belt for moving segments of limp sheet material onto the table for cutting. A cutting carriage and blade are mounted for controlled movement over the support surface of the table to cut pattern pieces from the limp sheet material positioned on the surface. A vacuum system holds the material in a compressed state on the support surface during cutting, and an air-impermeable overlay is spread on top of the cut material to seal the material and prevent leakage into the vacuum system. The overlay is an elongated strip with the opposite longitudinal ends wound into rolls. One roll is mounted on a self-retracting roller and connected with the cutting carriage to spread the overlay onto the cut sheet material as the carriage moves back and forth. The other roll is mounted on a motor driven roller at one end of the conveyor belt with the interconnecting portion between the rolls overlying the support surface of the table and any layup thereon. As the cut layup is moved off of the cutting table, the overlay material is retrieved by the motor driven roller. At periodic intervals, portions of the overlay strip accumulated on the motor driven roller are shifted back to the self-retracting roller mounted on the cutting carriage.
