Patent number: 9173488Abstract: A cabinet system modified to accommodate a fully retractable drawer within a drawer comprises a housing having a plurality of conjoined panels to define a first interior cavity and a first set of drawers slidably attached to tracks on the interior surfaces of opposing panels. Each drawer comprises a set of conjoined panels to define a second interior cavity panel, left panel, front panel, rear panel and bottom panel, wherein each panel has an interior surface and an exterior surface. Attached to the interior surfaces of each drawer's opposing panels is a track for slidably mounting a second drawer. When a first drawer is fully extended away from the first interior cavity, the second drawer can remain fully retracted within the first drawer or be fully extended into the first interior cavity.Type: GrantFiled: December 10, 2013Date of Patent: November 3, 2015Inventor: Thomas J. Bello

Patent number: 6130258Abstract: A method for resolving an oil-and-water emulsion is disclosed. The method comprises adding to the emulsion (1) if the emulsion does not contain a desirably high concentration of polyvalent metal cations of at least one part per million by weight, an amount of polyvalent metal cations sufficient to result in the desirably polyvalent metal cation concentration in the emulsion, and (2) an effective demulsifying amount of a combination of a terminating agent that is either a non-emulsifying hydrotrope composition or a coupling agent, and a composition comprising a polydithiocarbamate compound comprising at least two groups represented by the formula --(OR.sup.1).sub.X NHC(:S)SR.sup.2, wherein R.sup.1 represents an alkylene group of 1 to 30 carbon atoms, R.sup.2 represents an alkali or alkaline earth metal group or an ammonium group; and x represents an integer of from 1 to about 250 independently selected for each of such groups such that the total of the integers x is, on average, from 3 to about 250.Type: GrantFiled: October 7, 1998Date of Patent: October 10, 2000Assignee: Baker Hughes IncorporatedInventor: Thomas J.

Patent number: 5853592Abstract: Oil well production fluid composed of oil and water and containing in excess of 100 ppm water soluble petroleum carboxylates in anionic form dissolved in the water is treated by acidifying the fluid to a pH of 6.0 or lower with a combination of a strong organic acid and a strong mineral acid and then is intimately mixed. The oil and water are separated one from the other. The content of the water soluble organics in the water is thereby substantially transferred to the oil phase. In a second aspect of the invention, water used to extract corrosive compounds to render the oil suitable for fueling gas turbine power plants is acidified to a pH of 6.0 or lower and is thereafter intimately mixed with fuel oil.Type: GrantFiled: May 20, 1997Date of Patent: December 29, 1998Assignee: Baker Hughes IncorporatedInventors: Thomas J. Bellos, Gregory P. Noelken

Patent number: 5439592Abstract: A method for removal of water soluble organics from acidified oil process water is disclosed. The method comprises a step in which free oil is removed from such water by water-wet ultrafiltration to produce a water-rich filtrate stream which is then directed through a reverse osmosis membrane to produce a WSO-depleted stream and a WSO-rich reject stream. The method includes a recycle stream.Type: GrantFiled: September 1, 1994Date of Patent: August 8, 1995Assignee: Petrolite CorporationInventors: Thomas J. Bellos, Richard D. Keating

Patent number: 5329960Abstract: Disclosed is a valve assembly in which a valve is actuated by a flexible high pressure hose in cooperation with a commonly attached linkage. The valve assembly is attachable between a fire hose and a source of high pressure fluid. The assembly allows a user to open the valve to the high pressure fluid source from a remote location.Type: GrantFiled: December 1, 1993Date of Patent: July 19, 1994Inventor: Thomas J. Bello

Patent number: 4671815Abstract: This invention relates to salts of oxyalkylated amino compounds which render normally water insoluble components such as biocides, soluble in water and thereby improving their usefulness and effectiveness. These amino compounds render biocides such as methylene bis(thiocyanate) (MBT) and/or bis(trichloromethyl) sulfone (BTMS) water soluble. The soluble forms of these biocides afford more predictable, consistent and effective biocidal results when applied to systems contaminated with microorganisms such as bacteria, fungi, algae, molds, and certain yeasts and thus offer considerable advantages over insoluble, dispersible, emulsified forms of these biocides.Type: GrantFiled: September 13, 1979Date of Patent: June 9, 1987Assignee: Petrolite CorporationInventors: Thomas J. Bellos, Derek Redmore
