Title: Tampon applicator
IPC: A61F13/26
Filed: 1977-12-12
Abstract: A tampon applicator has an outer tube (1) containing the tampon (3), from which can be telescopically extended an inner tube (2) through which passes an extraction card (4).

Title: Method and apparatus for cleaning strip in a molten salt bath
IPC: B08B11/00
Filed: 1978-01-17
Abstract: Strip is cleaned by passing it through a molten salt bath in a rectangular tank having U-shaped heating tubes arranged horizontally along each longitudinal side of the tank. Agitators positioned within L-shaped ducts at diagonally opposite corners of the tank cause movement of the bath past the heating tubes, thus heating the bath uniformly and keeping it in motion to prevent sludge from settling out. A second tank arranged along one side of the main tank has two spaced apart openings into the main tank and an agitator which causes movement of molten salt therethrough. The second tank also has a settling chamber therein through which molten salt passes slowly so as to cause sludge to settle out.
Patent ES-467345-A1 (ES)
Title: Method of manufacturing products of cross-linked thermoplastic material
IPC: B29C48/475
Filed: 1978-02-27
Abstract: The process comprises forming a mixture containing a thermoplastic material and a cross-linking agent and causing the mixture to enter a die head. A pressure is exerted on the mixture in the die head along the axis of the die head so as to sinter the mixture. The die head is heated to a temperature lower than the temperature at which the cross-linking agent becomes substantially decomposed so as to cause fusion of the mixture and produce a formed material. The formed material is passed through a bath of molten salt downstream of the die head. The temperature of the molten salt is such as to achieve the decomposition of the cross-linking agent and the cross-linking of the formed material. A device is described for carrying out the process.

Title: Electromagnetic relay
IPC: H01H49/00
Filed: 1978-05-18
Abstract: An electromagnetic relay is provided in which the housing therefor is divided into two space areas, namely, one for the contacts, which is sealed off from a coil space area. The contact space is substantially sealed from the coil winding by having the carrier for the movable armature, the movable contacts and the stationary contacts on one side of a base body, and the coil on the other side. The contact area is provided by the base body and a protective cap. Stationary contact terminals are embedded in the wall of the base body. Spring biased movable contacts are mounted in the contact space. The protective cap closely adjoins the base body. The coil has a ferromagnetic core which at opposite ends of the coil have uprising flanges which form pole shoes. These flanges extend through openings in the base body in proximity to the armature. A permanent magnet means is also located in the contact space area in proximity to the pole shoes so when the coil is energized the carrier is shifted from one position to another to open and close switch contacts. The flanges are sealed to the base body and act as the supporting means for the coil.

Patent ES-8202141-A1 (ES)
Title: Method of compensation for target location changes when firing ballistic missiles
IPC: F41G7/34
Filed: 1981-04-03
Abstract: Changes in the location of targets when firing ballistic missiles from firing devices aligned with respect to a particular target position can be compensated for without the need to realign the firing devices by establishing trajectory correction values which take into account the relation between the firing direction of the firing device and the expected position of the target when a missile fired in the firing direction will reach the position the firing direction was set for the missile to reach. These correction values are introduced before or at firing into an electronic storage means of the missile and after a predetermined time of flight cause the trajectory of the missile to be altered so that it is redirected towards the target's expected position by release of signals from the electronic storage means to trajectory adjusting means of the missile, such as fins, auxiliary rockets or jet-deflecting devices.

Filed: 1981-05-29
Abstract: Characters stored in a memory 44 are displayed in rows and columns on a display means 11, the rows and columns being counted by a video row counter 49 and a video column counter 45. The address generator 53 for memory 44 includes a roll register 90, the count of which is added (mod the number of rows) to the video row count by a PROM 91, thereby scrolling the display the PROM 91 is divided into blocks by the video row count, the blocks containing modular addition tables. However, certain blocks are instead filled with just the video row count. This results in the corresponding rows in memory 44 (used for system control information), stored in fixed locations in memory 44, appearing in fixed rows on the display, unaffected by scrolling of the variable data in most of the memory and display. A second PROM 92 combines the adjusted row count with the column count.
