Abstract:
A rapid disintegrating and dispersing composition for thickening liquid waste into a thixotropic gel comprises a polymeric acrylic resin and a colloid-forming mixture of microcrystalline cellulose and sodium carboxymethylcellulose. Additional ingredients preferably used in making a tableted form of the composition include microcrystalline cellulose per se, polyvinylpolypyrrolidone, magnesium stearate and amorphous silica. The tablet is placed in suitable containment means such as a containment bag. The thixotropic properties of the composition enable the gelled waste to be restored to a liquid when small amounts of hand pressure are applied to the waste containment bag, thereby providing a convenient and simple means for disposal.

Abstract:
Procedimiento continuo para hacer piezas elementales ara cajas de cartón o cartulina, qeu comprende las operaciones de: formar una hoja fibrosa afieltrada continua y gruesa, partiendo d euna papilla acuosa de fibras, sobre una máquina de afieltrar continua; hacer pasar la hoja así formada por una serie de rodillos de escurrido, eliminando así por compresión el agua de dicha hija; rayar unas líneas de doblez en dicha hoja escurrida, para doblar dicha pieza elemental en forma de caja o recipiente; y secar la hoja rayada.
Abstract:
A process for the heterogeneous synthesis of chemical compounds such as methanol and ammonia through catalytic conversion of the respective gaseous reactants that are made to pass through a first (2) and a second (3) reaction zone connected in series with each other, in which they react in pseudoisothermal conditions, distinguishes itself in that in the first reaction zone (2) the gaseous reactants are made to flow through a fixed mass of an appropriate catalyst in which a plurality of substantially box-like, plate-shaped heat exchangers (21), arranged side-by-side and crossed by a heat exchange operating fluid, is dipped.
