Title: Aluminum alloy two-step aging method and article
Inventor: RIOJA ROBERTO J
IPC: C22F1/057
Filed: 1989-02-28
Granted: 1993-06-29
Abstract: Abstract of the Disclosure A method for thermally treating an article made from an aluminum alloy having a first temperature at which solute atoms cluster to yield nuclei for the formation and growth of strengthening precipitates, and a second higher temperature at which the strengthening precipitates dissolve.  The method comprises:  heating the article to allow substantially all soluble alloy components to enter into solution; rapidly cooling the article in a quenching medium; and precipitation hardening the article by aging at or below the first temperature for a few hours to several months; then aging above the first temperature and below the second temperature until desired strength is achieved.  A method for imparting improved combinations of strength and fracture toughness to a solution heat treated article which includes an aluminum-lithium alloy is also disclosed.  This method comprises aging the article at one or more temperatures at or below a first temperature of about 93°C (200°F) for a few hours to several months; and further aging the article at one or more temperatures above the first temperature and below a second temperature of about 219°C          (425°F) for at least about 30 minutes.

Abstract: ABSTRACT OF THE DISCLOSURE Ultra-rapid annealing of grain oriented electrical steel to a temperature prior to the final high temperature anneal results in improved texture and smaller secondary grain size.  The ultra-rapid anneal requires heating the strip to a temperature above about 675°C (1250°F) at a rate above 100°C per second (180°F per second). The ultra-rapid anneal is performed after coldrolling and prior to or as part of the decarburization anneal. The material willsurvive a subsequent stress relief anneal or may be further improved by various domain treatments. The ultra-rapid anneal increases productivity and produces improved core loss properties.

Abstract: ABSTRACT OF THE DISCLOSURE       An underground water warmed by the geothermy in an aquifer is pumped up by a pumping means disposed in a pump-up  well  and  the  pumped  up  underground  water  is introduced into a heat exchanger located in the pump-up well near the opening thereof.   The heat exchanger is connected to a heat radiating pipe laid under a road or a building structure on the ground through feed and return conduits.   An antifreezing fluid is filled in the heat radiating pipe and circulates through the heat radiating pipe and the heat exchanger through the conduits.   The antifreezing fluid warmed in the heat exchanger by the heat exchanging operation stores the heat in the road and transfers the heat to the snow on the ground during the passing  through  the  heat  radiating  pipe  by  the  heat radiating operation, whereby snow lying on the road is melted without sprinkling water.   The underground water cooled after the heat exchanging operation is discharged from the heat exchanger to be introduced into a water returning  artesian  well  to  store  the  water  or  to be discharged into a public discharge channel.

Abstract: ABSTRACT OF THE DISCLOSURE     A transfer apparatus is disclosed for transferring a web from a press section to a first dryer of a dryer section.  The apparatus includes a lead-in roll which is disposed closely adjacent to the press section.  A felt extends around the lead-in roll and from the lead-in roll to the first dryer such that the web extends in an "open draw" from the press section to the lead-in roll and is thereafter supported by and beneath the felt towards a dryer nip defined between the felt and the first dryer.  A vacuum generating device is disposed adjacent to the dryer nip such that the web and the felt are disposed between the vacuum generating device and the first dryer.  The web is disposed between the felt and the first dryer, and the vacuum generating device induces a partial vacuum in the vicinity of the nip so that wrinkling and breakage of the web as the web approaches the nip is inhibited.

Abstract: This invention relates to a method for the recovery of organic substances dissolved or brought into a colloid form during the manufacture of a mechanical pulp where said mechanical pulp has not been subject to previous alkaline bleaching or other previous process carried out under alkaline conditions. The method is characterized in the deacetylation of the galactoglucomannans having been brought into dissolved or colloidal form during the pulping process, and subsequent deposition of said deacetylated glucomannans onto a solid phase, such as pulp fibres or organic or inorganic additives. The deacetylation is performed either by alkali or enzymatically. The method diminishes the organic substance loading on recycling waters and effluents, and improves the yield and strength properties of the pulp.
