Abstract: A method, a waterproof liner and waterproof panels for installations in basins and canals (10) both dry and with stationary and flowing water. The liner consists of a plurality of prefabricated panels (14; 14A) comprising at least one flexible waterp¬roof membrane (16), made of geosynthetic material, provided with side anchor bands (23) for anchoring to the ground and with side sealing flaps (26); the panels (14; 14A) that are rolled up into rolls are sequentially unrolled and extended by fixing provisionally along at least one anchor band (23), by joining simultaneously the flaps (26) of adjoining panels (14; 14A) by means of an intermediate zip fastener (28). Subsequently, the individual panels (14; 14A) are firmly anchored by friction to the bottom (11) and/or to the banks (12) of the basin or canal (10), by means of a permanent ballast (30). According to a first solution, the panels (14) comprise superimposed waterproof memb¬ranes (16, 17) made of geosynthetic material, and are configured with filling chambers or cells (18) into which a ballast cementitious mixture is injected; in a second solution each panel (14) consisting of a single flexible membrane (16) made of geosynthetic material, permanently ballasted by prefabricated blocks of concrete (49); in a third solution the panels (14A) comprises a first waterproof membrane (16) and a second waterproof membrane (50) folded in a tubular shape and welded to the first watertight membrane (16). The individual panels (14; 14A) can be removed and replaced by operating underwater, restoring the seal between panels (14; 14A) of the entire waterproof liner. s

Granted: 1993-05-04
Abstract: ABSTRACT      A fasciated yarn suitable for making apparel fabric and having properties approaching that of ring spun yarn is produced by vacuum spinning, including directly from sliver.  The elongated hollow shaft (20) of the vacuum spinning apparatus has a vacuum reservoir (32), or interior chamber, that is generally in the shape of a right circular cone, and the interior passageway (31) of the shaft from the first end (21) thereof to the interior chamber can have the form of a right circular cone frustum.  The peforations (40) operatively connected to the interior chamber have a generally wedge-shape.  The perforations and the passageway sections between the first end of the shaft and the perforations are dimensioned so that they allow sufficient air flow to achieve optimum fiber wrapping action.  The fasciated yarn comprises vacuum spun yarn consisting of fibers including core fibers and wrapper fibers, the wrapper fibers being predominantly individual fibers although having some groups of wrapper fibers.  The groups of wrapper fibers appear as non-uniform, non-consistent groups and provide a relatively smooth appearance. The wrapper fibers are wrapped at a helix angle of about 30° (e.g. about 30-50°), and about 20-30 percent of the fiber mass comprises the wrapper fibers.  The wrappers are essentially devoid of auger or corkscrew appearance.  The core fibers are essentially parallel staple fibers.  Initial threading of the vacuum spinning apparatus is provided by a vacuum tube (745) mounted for rotation about an axis parallel to and spaced from the axis of rotation of the shaft, the vacuum tube being connected up to a vacuum reservoir (742) and source of vacuum (728) and rotatable from an inoperative to an operative position.

Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE           A method and unitary apparatus purifies solid metallic gold.  For that purpose, the gold to be puri-fied is  immersed and  electrolytically  dissolved into a pregnant electrolyte comprising an aqueous solution of a halide ion source impregnated with a catalyst, preferably a peroxide or a nascent oxygen source, for leveling the overvoltage of gold.   The dissolved gold ions are segregated from the cathode by a semi-perme-able barrier,  the insoluble impurities are separated from the gold-containing liquidus, and then the gold is selectively reduced to metallic form from the liquidus by a selective  chemical  reducing  agent.   With  this method and apparatus, gold in metallic form of at least 99.95% purity can be obtained.

Abstract: METHOD OF PREPARING YEAST-LEAVENED           BREAD CRUMBS                     ABSTRACT A method of preparing yeast-leavened bread crumbs suitable for use in a stuffing mix.  A fully developed bread dough which has a generally low water content of not more than 60% based on flour weight, is sheeted and baked in sheet form.  The dough sheet has a thickness of 1/4 to 3/4 inches. Proofing of the dough is limited to provide a baked sheet having a density of from 17 to 36 pounds per cubic foot.  After cooling, the baked bread sheet is subjected to staling for a maximum of ten hours. The staled sheet is then divided into bread crumbs. The entire process, after providing the developed dough, is preferably carried out in not more than twelve hours.  The short processing time is largely attributable to the relatively short staling period.

Title: Method for generating a lattice structure with a phase shift on the surface of a substrate
Inventor: HEISE GERHARD
IPC: G03F7/20

Granted: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE          A method for generating a lattice structure with a phase shift on a surface of a substrate characterized by the steps of exposing of a photo-sensitive surface in an optical interference field and then subsequently exposing the same surface to a second interference field with the spatial frequencies of the two interference fields being changed a small amount between the two exposures.  The photo-sensitive surface can be a photoresist layer applied on the substrate.  After developing of the layer, this lattice structure is produced by etching.  Another embodiment of the method is produced by means of a laser-active etching wherein the photo-sensitive surface is composed of a substrate surface in contact with an etchant and the etchant reaction is activated by the exposure.
