Patent ES-460337-A1 (ES)
Title: A procedure for the manufacture of new stable abrasive cleaning liquid compositions.
IPC: C11D1/72
Filed: 1977-07-01
Abstract: A procedure for the manufacture of new stable abrasive cleaning liquid compositions. This invention refers to liquid cleaning compositions containing an insoluble abrasive material and which are used as cleaners for hard surfaces.  Homogeneous liquids of this type offer obvious advantages over the solid abrasive cleaners in cleaning hard surfaces.  They can be applied in easily manageable quantities to the surfaces whilst the solid cleaners must be dissolved in water before cleaning can take place.  However, the formulation of an adequate composition is not simple.  In particular, the abrasive particles are generally denser than the liquid medium in which they are suspended and tend to deposit like sediment.  Furthermore, it is necessary that the composition be quite viscous so that it can be easily applied.  It is also necessary that the liquid medium maintains its homogeneous character and is capable of maintaining the abrasive in homogeneous suspension during prolonged periods of storage.
Patent ES-462496-A1 (ES)
Title: Screen printing apparatus
IPC: B41F15/40
Filed: 1977-09-20
Abstract: A squeege structure for a screen stencil of a printing machine comprises an elongated carrier frame and a squeegee coupled to the carrier frame by a thrust drive for moving the squeegee between operative and nonoperative positions. The thrust drive includes a central first thrust drive unit and a plurality of second thrust drive units mounted on each side of the first thrust drive unit. The movable portion of the first thrust drive unit may only move along its thrust axis which is in a direction perpendicular to the longitudinal axis of the carrier frame and is restrained from moving in a direction perpendicular to the thrust axis. The movable members of the second thrust drive units may move along their thrust axes and may also move in a direction perpendicular to the thrust axis and parallel to the longitudinal axis of the carrier frame, but may not move in a direction perpendicular to both the thrust axis and the carrier frame longitudinal axis. This structure permits the first and second thrust drive units to be flexibly coupled to compensate for deflection of the carrier member to avoid seizing of the first and second thrust drive units and provide uniform pressure along the entire length of the squeegee.
