Patent ES-479778-A1 (ES)
Title: Safety closure device
IPC: F16K21/04
Filed: 1979-04-20
Abstract: The device comprises a conduit 1 for introduction to a pressurised distribution system and a piston 31, 32 automatically displaceable to sealingly cooperate with seating 8 in the event of excessive pressure differential across the piston, e.g. due to a fracture in a downstream pipe. The piston is re-opened by knob 42. As shown, in the normal equilibrium position of the piston, fluid flow is established between the inlet 13 and outlet 12 via arcuate passages 33, 34 in two relatively rotatable piston parts 31, 32. Relative rotation of the latter adjusts the flow duct section at 33, 34 to set the pressure difference across the piston for normal flow conditions. Axial movement of the piston is restrained, as by the frictional grip provided by seal 6, to maintain the piston in its equilibrium position until a threshold value of the pressure difference is exceeded. Other embodiments incorporate, respectively, adjustable magnets and a diaphragm subjected to fluid pressure to provide the axial restraining means. The drive for rotating the relevant piston part may include gearing.

Title: Apparatus for operating on hollow workpieces.
IPC: B21D17/04
Filed: 1979-06-13
Abstract: In a rotary turret-type machine, in which operations are performed on successive can body cylinders (8) or the like by a mandrel (159) inside the workpiece co-operating with a beading rail (176), each workpiece is guided smoothly into a cradle (151) which so supports and locates it throughout its stay in the machine that axial movement of the mandrel is unnecessary. Each cradle is reciprocated towards and away from the mandrel by a fixed cam (145). Each cradle has a spring loaded support roller permitting eccentric support of the can body during beading. Each mandrel preferably has a quick-acting coupling (200) permitting temporary radial displacement of the mandrel without loss of parallelism to accommodate a can body side seam. This coupling consists of a spring mounted support plate (305) engaging a register plate (304) through three balls (306) mounted in seats (307) in the rings to give radially-yielding tripod support.

Patent ES-8107301-A1 (ES)
Title: Stable high copy number plasmids, their formation and use in protein production.
IPC: C12N15/00
Filed: 1979-12-24
Abstract: The problem of producing stable DNA plasmids of high copy number is solved by selecting mutants in which an altered repressor gene leads to high copy number replication. Translocatable elements in the plasmids are disabled in such a way that readthrough expression of heterologous DNA inserted in the plasmid will not continue into the translocatable elements or into elements which as a result of expression mediate rearrangement of said translocatable elements. Such plasmids may be used to produce a desired protein by introducing them into the genetic system of a host organism and permitting the organism to grow and phenotypically express its genotype. The invention also includes a method for removing 3 min cutting restriction sites and maintaining 5 min cutting restriction sites in DNA comprising cutting the DNA with appropriate restriction enzymes, treating the cut fragment with the enzyme DNA polymerase I in such a manner that 3 min single stranded tails are removed and 5 min single stranded tails are repaired to double stranded form, and blunt-end ligating the fragment to its previous orientation.
