Patent ES-454796-A1 (ES)
Title: Closed torus tire
IPC: B29D30/08
Filed: 1977-01-04
Abstract: Method and apparatus for building a cord or wire wound carcass for a closed torus tire. An endless flattened inflatable tube providing a liner for the carcass and coaxially spaced bead rings are placed on a support comprising a cylindrical array of rolls. The bead rings are spaced axially to control the length of each turn of cord or wire wound in the flattened oval path around them. A single wire or cord is wound in a flat oval orbit about the liner and bead rings by orbiting a spool along a track having two straight parallel portions, one inside, the other outside the bead rings and liner. The parallel track portions are connected at their ends by semi-circular track portions. No rigid core is required. After winding the cord or wire about the liner and bead rings, the liner is inflated and the bead rings are shifted axially toward each other to the axial spacing appropriate for the inflated tire in use.

Title: Detection of gases
IPC: G01N25/50
Filed: 1979-08-01
Abstract: A method of detecting the presence of a foreign gas in a gaseous medium of known combustion properties uses the fact that the percentage lower or upper explosive limits (LEL or UEL) of mixtures of any flammable gas in any other gas all have approximately the same varying relationship to the percentage LEL or UEL of the mixture as a whole when a known percentage of a reference gas of known combustion properties is added to the mixture. The method comprises the steps of mixing a sample of a possibly contaminated gaseous medium with known combustion properties in a fire-safe container (12), actuating ignition means (17) in an attempt to ignite the gaseous mixture in the container (12), and using detection means (18) to detect ignition or otherwise of the gaseous mixture to enable the presence of a foreign gas above a predetermined concentration in the gaseous medium to be detected. Apparatus for use in this method comprises in combination with the fire-safe container (12), means (15) for introducing the sample of possibly contaminated gas into the container, valve means for introducing a known quantity of the reference gas into the container, and ignition and detection means (17,18) to permit and monitor attempts at ignition of the sample.
Patent ES-485009-A1 (ES)
Title: Current limiting circuit interrupter with improved operating mechanism
IPC: H01H77/10
Filed: 1979-10-15
Abstract: A current limiting circuit interrupter includes two parallel pivoting contact arms carrying contacts at the ends thereof. The upper contact arm is pivoted upon a carriage which is in turn pivotally mounted upon a mechanism frame. A latch rod is movably secured in arcuate slots in the sides of the mechanism frame. When the circuit interrupter is in the closed circuit position, a pair of springs connected between the latch rod and the carriage urges the latch rod against a reaction surface of the upper contact arm to provide contact closing pressure. Upon occurrence of severe overload current conditions, the upper contact arm pivots upon the carriage, moving the latch rod within the arcuate slots to release the contact closing pressure, allowing the springs to move the latch rod against a latching surface of the upper contact arm to latch the upper contact arm in the open circuit position.

Title: Machine for forming a tubular profile.
IPC: B31C5/00
Filed: 1980-06-10
Abstract: In a machine for forming a continuous tube which is then cut up into sections, for example to make containers, a plurality of bands of fibrous, cellulosic, metallic, plastic or other material are drawn from supply reels and pass through a gluing and labelling section where adhesive is applied to one side of the bands and labels are applied to the outer face of the center band. After application of the adhesive and labels, the bands, while continuing to move forwardly, are assembled in superposed relation with the bands laterally displaced relative to one another so that the edges of the assembly of bands are stepped. The bands are pressed together in a narrow central width only so as to bond central portions together while leaving side portions unbonded. The band assembly is then progressively formed into tubular profile, thereby bringing opposite side edges together, and subjected to pressure to bond the bands together throughout their width, bond side edges together and impart the finished shape, which may be circular or polygonal. The tubular profile thus formed is cut into sections while it continues to move forwardly and the sections are discharged from the machine.

Abstract: A process for the recovery of maleic anhydride contained as a by-product in a phthalic anhydride gaseous reactor effluent is described. This process consists of gas scrubbing in order to obtain an aqueous solution of the maleic acid and the other organic substances contained in the gas, including phthalic acid, concentration of this solution as maleic acid to a concentration of 25-35 % by weight by addition of a return stream to the solution and removal of the phthalic acid by crystallisation.
