Title: Manufacture of solid ammonium phosphate
IPC: C05B7/00
Filed: 1975-09-12
Abstract: The invention relates to a process for the manufacture of solid monammonium phosphate with good granulation properties suitable for use in compound fertiliser manufacture. An improvement in product quality is obtained when between 20% and 80% of an aqueous slurry of ammonium phosphate, formed by the ammoniation of wet-process phosphoric acid, is mixed with a second acid prior to entry into a moisture disengagement unit.

Patent ES-468946-A1 (ES)
Title: Blow molding method
IPC: B29C49/04
Filed: 1978-04-19
Abstract: Thermoplastic pre-forms which are obtained as a result of expansion of parisons in a pre-form blow mold are transformed into bottles or analogous hollow shaped articles in a final blow mold. The first stage of transformation involves mechanical stretching of the pre-form in the cavity of the final mold simultaneously with or prior to admission of a compressed blowing fluid to expand the major portion of the pre-form into contact with the adjacent surface of the final mold. The next stage involves admission of the blowing medium at a higher pressure to effect abrupt biaxial expansion of the closed end and of the portion intermediate the closed end and the major portion into contact with the adjacent surfaces of the final mold. The configuration of surfaces which are contacted by the bottom and intermediate portion of the shaped article is such that radial expansion of the corresponding portions of the pre-form in response to admission of blowing fluid at an elevated pressure necessarily takes place simultaneously with axial expansion. This is achieved by employing a final blow mold with a fixed internal bottom surface which causes the bottom of the shaped article to assume a concavo-convex shape, or by employing a final mold whose bottom surface is movable in a direction to reduce or increase the volume of the cavity prior to admission of blowing fluid at elevated pressure.

The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)
