Patent number: 5271762Abstract: Adsorbers used to dry air frequently contain 4A or 13X molecular sieve zeolites, which are intermittently reactivated by thermal regeneration. When the air pressure in a thermally regenerated adsorber is increased, such as during start-up, after adsorbent reloading, after apparatus repair, maintenance or inspection, or after repressurization following thermal regeneration, nitrogen adsorbs preferentially relative to oxygen in activated 4A and 13X molecular sieve zeolites. This produces an oxygen-enriched, high pressure gas within the adsorber vessel which emerges immediately after the adsorber is brought on line. The oxygen-enriched, high pressure gas can cause fires, explosions, and other deleterious effects in and downstream of such adsorber vessels. This invention provides thermally regenerated air driers and air drying processes using adsorbent compositions that do not adsorb nitrogen preferentially to oxygen.Type: GrantFiled: September 29, 1992Date of Patent: December 21, 1993Inventors: Gregory R. Schoofs, Richard J. Schoofs

Patent number: 5147419Abstract: Adsorbers used to dry air frequently contain 4A or 13X molecular sieve zeolites, which are intermittently reactivated by thermal regeneration, When a thermally regenerated adsorber is repressurized, nitrogen adsorbs preferentially relative to oxygen in activated 4A and 13X molecular sieve zeolites. This produces an oxygen-enriched, high pressure gas within the adsorber vessel which emerges immediately after the absorber is brought on line. The oxygen-enriched, high pressure gas can cause fires, explosions, and other deleterious effects in and downstream of such adsorber vessels. This invention provides thermally regenerated air driers, adsorbent chambers and air drying processes using adsorbent compositions that do not adsorb nitrogen preferantially to oxygen. Thermally regenerated air driers, adsorbers and drying processes using such adsorbent compositions prevent the problems associated with transient oxygen enrichment.Type: GrantFiled: July 19, 1990Date of Patent: September 15, 1992Inventors: Gregory R.

Patent number: 4674243Abstract: A spacer bar for use in double glazed windows is disclosed. The spacer bar is an elongated tube or conduit having a generally rectangular cross section. The spacer bar has two pairs of opposing planar faces. Each planar surface of one pair lies against the interior surface of one of the glass panes of the double glazed window and one planar surface of the other pair faces the space between the panes and the other planar surface of said other pair faces the atmosphere. A small diameter tube passes through the surface facing the atmosphere. The portions of the small diameter tube lying on either side of the conduit surface are bent downwardly. The portion of the small diameter tube which lies inside the conduit is bent downwardly and extends to a point at least 5 inches below its entry point and the other portion of the small diameter tube which lies outside the conduit is also bent downwardly so that it lies adjacent to and generally parallel to the outer face of the conduit.Type: GrantFiled: September 10, 1984Date of Patent: June 23, 1987Assignee: Schoofs IncorporatedInventor: Richard J.

Patent number: 4508699Abstract: An improvement in the Claus Process for producing sulfur by reaction of hydrogen sulfide with sulfur dioxide at elevated temperature in the presence of a porous catalyst is described. The improvement lies in employing a porous catalyst, preferably alumina, having a large surface area at least 40% of which is provided by pores having diameters over the range 40 A.degree. to 150 A.degree. or having at least 20% of its surface area provided by pores having diameters over the range 80 A.degree. to 150 A.degree..Type: GrantFiled: January 13, 1984Date of Patent: April 2, 1985Assignee: Schoofs, Inc.Inventor: Richard J.
