Title: Manufacture of high purity zirconia from low-silica zirconiferous materials.
Inventor: SINHA HARI NARAYAN
IPC: C22B34/14
Filed: 1987-06-17
Abstract: High purity ZrO2 is obtd. from low SiO2-contg. zircon material by leaching with H2SO4 at 175-250 deg.C, the H2SO4 concn. being such that it boils at the leaching temp. The temp. is pref. 200-250 deg.C and the H2SO4 concn. is 80-88 wt.%. Leaching is initiated with 98% H2SO4 at 175-250 deg.C and the water then produced by the leaching dilutes the H2SO4 until its concn. is such that it boils. The starting material is caustic-leached, plasma-dissociated zircon. The high purity ZrO2 prod. is claimed.

Title: Prodn. of pulsating currents with different amplitudes
Inventor: RODRIGUEZ DIONISIO
IPC: H02K39/00
Filed: 1987-12-21
Abstract: The method is intended for prodn. of pulsating currents with different amplitude of the pulses and is based on establishing in each phase of the transformer primary which feeds the electrolytic chain of one or more tappings which correspond to different voltages. These tappings are used selectively to obtain corresponding pulses of different current amplitudes at the outlet. The conduction times are a multiple of the number of tappings establised in each phase of the primary, to balance the transformer functionally. - The method replaces the current amplitude differences achieved by varying the conduction angle of the thyristors which control the transformer primary, resulting in a substantial energy saving.
Patent ES-2005499-A6 (ES)
Title: Dealkalized sheet glass
Inventor: HECO ANDRE
IPC: C03C21/00
Filed: 1987-12-01
Abstract: Dealkalized sheet glass having a core region which is not dealkalized, having a pre-dealkalization bulk sodium ion concentration of at least 8%, calculated as weight percent sodium oxide in the sheet glass, which pre-dealkalization bulk sodium ion concentration continues to be maintained in the core region of the sheet glass, and having a surface which is dealkalized to a depth such that a sodium ion concentration gradient exists. The sodium ion depletion is maximum at the surface, the depth at which the sodium ion concentration is 90% of the pre-dealkalization bulk sodioum ion concentration is at least twice the depth at which the sodium ion concentration is 50% of the predealkalization bulk sodium ion concentration, and the sodium ion concentration at a depth of 50 nm is not more than 50% of the pre-dealkalization bulk sodium ion concentration. A long-lasting dealkalization is achieved because of a reduced tendancy to ionic migration due to the shape of said sodium ion concentration gradient.

Title: Decorative high-pressure laminate and a process for producing a surface layer thereon.
Inventor: HOLZER DR HERBERT
IPC: B44C5/04
Filed: 1989-11-16
Abstract: The invention concerns the production of a decorative high-pressure laminate with a surface layer (3) on the surface of which an adhesive primer layer (4) of polyvinyl butyral is applied. The adhesive primer layer (4) enables a lacquer coating to be applied subsequently, so that a lacquer layer optimally suited to the particular application for which the laminate is eventually used can be chosen. The adhesive primer layer (4) can be applied by impregnating a web of paper with melamine resin, dusting the impregnated web with polyvinyl butyral powder while the resin is still wet and then drying. Another way of producing the coat is to apply polyvinyl butyral in alcoholic solution to a web of paper which has been impregnated with melamine resin and dried, and subsequently drying.

Title: Process for manufacturing floor tiles (paving stones), covering tiles and ceramic paving
IPC: B28B3/00
Filed: 1990-04-16
Abstract: Shaping and enamelling of the "untreated" piece takes place at the pressing station. To this end, the press receives, firstly, moistened pulverulent clay and, secondly, a dry enamel sheet which is positioned on the clay charge. Next, joint pressing of the clay and enamel sheet takes place, resulting in an already enamelled "untreated" piece. The process makes it possible to dispense with the enamelling lines of the production chain and the auxiliary enamelling preparation sections.
