Patent ES-8301520-A1 (ES)
Title: Anti-graffiti facing of walls or similar surfaces.
IPC: B05D5/00
Filed: 1981-07-17
Abstract: Facing of a wall or similar surface primarily for anti-graffiti purposes is effected by firstly the application thereto of a primer and sealing bonding agent such as a resin which may contain a proportion of aggregate such as china clay. This seals the surface and provides an adhesive coating for receiving a further coating composition, e.g. in paste form. The further coating composition comprises setting and filler materials such as gypsum and china clay respectively together with a resin binder and also a hardening and strengthening constituent such as mica. On setting, the coating composition provides a hard indentation resistant surface, but prior to setting, the surface is textured preferably to a pattern. A finish coating of cellulose based paint is then applied to the surface so that it can be over-sprayed by the same kind of paint to obliterate aerosol spray paint graffiti marking on the surface. The coating composition is preferably dyed with colouring matter at least approximating in colour to that of the finish paint coating.
Patent ES-8205580-A1 (ES)
Title: Method for improving the electrical conductivity of a steel surface having a coating of ferrous oxide.
IPC: B03C3/74
Filed: 1981-09-21
Abstract: The electrical conductivity of metallic surfaces may be regenerated in situ by treating the surface with a regenerating agent in the form of a hydrogen halide such as hydrogen chloride. Hydrogen halide may be utilized in either liquid, gaseous or vaporous form. If so desired, an ammonium salt such as ammonium chloride may also be used to enhance the regenerative powers of the hydrogen halide. For example, the surface of steel may be treated with hydrogen chloride and ammonium chloride to enhance the formation of ferric oxide which possesses a greater electrical conductivity than does ferrous oxide.
Patent ES-8301646-A1 (ES)
Title: Seat belt retractor assembly with post emergency spool release.
IPC: B60R22/40
Filed: 1981-09-21
Abstract: An emergency spool release for use with a seat belt retractor mechanism is shown wherein the seat belt mechanism includes a spool for storing a belt which restrains the passenger of a vehicle during an emergency. The belt is urged into a retracted position by spring means while the protracted position of the belt is restrained in an emergency by the automatic engagement of a locking pawl against ratchet teeth found on the periphery of the spool. The automatic engagement is accomplished by an inertia locking system. In some situations, the automatic inertia locking system does not disengage thereby making it difficult to accomplish further protraction of the seat belt in a post emergency situation. The locking pawl in the seat belt mechanism of this invention is capable of a rotational motion to engage the ratchet teeth under the urging of the inertia locking device. It is also capable of a transverse motion under the urging of a manual unlocking device for post emergency release. Transverse motion of the locking pawl is accomplished by a lever which is attached to the locking pawl and spring biased into the automatic position. Actuation of a lever either manually or by a second lever mechanism causes the transverse motion of the locking pawl to unlock the seat belt mechanism in the post emergency condition.

Title: Wire electrode spark erosion.
IPC: B23H1/00
Filed: 1982-02-12
Abstract: Hardmetal lamina are cut, by a process known as electrical discharge machining, from a block of hardmetal using a wire electrode. The laminae so formed may then be attached by adhesive or epoxy resin to a suitable base in order to form a hard metal surfaced tool. Provision is made for preventing this hardmetal from shearing from its mounting, and also to remove any heat generated within the hardmetal. Reference is made especially to using the above construction for a 'slipper' within a tile producing machine. The word 'hardmetal' is used to denote powdered carbides of the transition metals, cemented into solid masses by a matrix of a metal of a lower melting point.

Title: Clutch control means.
IPC: B60W30/18
Filed: 1982-04-06
Abstract: An electronic control for a vehicle transmission having a clutch, the engagement of which is controlled in response to a clutch engagement signal. An electronic speed ratio logic for selection of the appropriate transmission gear ratio can produce a disengagement signal which overrides the engagement signal to cause disengagement of the clutch. A limiter is activated by a gear change signal from the logic to produce a limit signal which partially overrides the engagement signal to prevent full engagement of the clutch when the disengagement signal ceases, and the gear change signal is in operation.

Patent ES-8502287-A1 (ES)
Title: Apparatus and method for monitoring stored material
IPC: G21F9/36
Filed: 1982-08-25
Abstract: An apparatus and method for monitoring stored material is disclosed. Material to be stored and monitored is placed within the innermost container of a series of nested containers and monitoring fluids are circulated in a closed loop of fluid flow through the spaces between the nested containers. Monitoring devices are used to analyze said monitoring fluids to detect leakage of the stored material from the innermost nested container and to detect the migration of external fluids into the series of nested containers. A computer based monitoring system continually checks the values of various parameters of the monitoring fluids to immediately detect and report the presence of stored material or external fluid in the monitoring fluids. The stored material may then be immediately retrieved from storage to repair leaks in the series of nested containers. The invention is particularly suited for monitoring the storage of hazardous material such as radioactive waste material.

Patent ES-8501253-A1 (ES)
Title: Reaction drive sprinkler
IPC: B05B3/08
Filed: 1983-05-11
Abstract: A reaction drive sprinkler, particularly of the large gun type, is provided with an improved drive assembly adapted for full- or part-circle rotation of the sprinkler in steps about the axis of a water supply standpipe. The sprinkler includes a relatively large and outwardly inclined range tube from which a relatively high energy water stream is projected a substantial distance for irrigation purposes. The drive assembly comprises a drive nozzle mounted on the range tube for bleed passage of a relatively low energy portion of the irrigation water supplied to the range tube and for directing this low energy stream into engagement with one of a pair of oppositely angled deflector spoons at the end of a counterbalanced and pivotally mounted reaction drive arm. The drive nozzle is movable with respect to the range tube and is mechanically shifted by a reversing mechanism for aligning the low energy stream first for cyclic interruption by one of the deflector spoons to rotate the sprinkler stepwise in one direction through a preselected arcuate path and then for cyclic interruption by the other deflector spoon to rotate the sprinkler stepwise in an opposite rotational direction back through the preselected path. In one preferred form, the range tube is supported for rotation by a bearing assembly which includes a force-biased seal member responsive to increasing water pressure for increasing frictional resistance to rotation whereby the stepwise movement of the sprinkler is maintained substantially uniform throughout a range of water pressures. Moreover, the range tube is advantageously provided with a discharge nozzle assembly which is adjustable to select the angle of inclination of the projected high energy water stream.
