15 Feb 2000TL;DR: In this article, the use of the highly viscoelastic low molecular weight polymer in combination with the higher molecular weight thickener enables the production of very widely cross-graded engine oils, especially oils with a low temperature grading of 0W or better.
Abstract: High performance engine oils and other liquid lubricants comprise a liquid lubricant basestock of low viscosity from 1.5 to 12 cSt (110C) with two dissolved polymer components of differing molecular weights. The basestock is preferably a single PAO or blend of PAOs with a co-basestock component which is preferably an ester or an alkylated aromatic of comparable viscosity. The lower molecular weight polymer is highly viscoelastic in character and is preferably an HVI-PAO; this component in the lubricant which provides unexpectedly high film thickness and unexpectedly good wear protection under conditions where the second, higher molecular weight polymer may lose some or all of its thickening power. The use of the highly viscoelastic low molecular weight polymer in combination with the higher molecular weight thickener enables the production of very widely cross-graded engine oils, especially oils with a low temperature grading of 0W or better. Oils with cross gradings of 0W20, 0W30, 0W40 or even more widely cross graded, for example 0W70 or higher may be achieved.

TL;DR: The southern Whidbey island fault as discussed by the authors is a dextral strike-slip fault along the eastern side of a continental margin rift that is capable of generating large earthquakes (M s ≥ 7).
Abstract: Information from seismic-reflection profiles, outcrops, boreholes, and potential field surveys is used to interpret the structure and history of the southern Whidbey Island fault in the Puget Lowland of western Washington. This northwest-trending fault comprises a broad (as wide as 6–11 km), steep, northeast-dipping zone that includes several splays with inferred strike-slip, reverse, and thrust displacement. Transpressional deformation along the southern Whidbey Island fault is indicated by along-strike variations in structural style and geometry, positive flower structure, local unconformities, out-of-plane displacements, and juxtaposition of correlative sedimentary units with different histories. The southern Whidbey Island fault represents a segment of a boundary between two major crustal blocks. The Cascade block to the northeast is floored by diverse assemblages of pre-Tertiary rocks; the Coast Range block to the southwest is floored by lower Eocene marine basaltic rocks of the Crescent Formation. The fault probably originated during the early Eocene as a dextral strike-slip fault along the eastern side of a continental-margin rift. Bending of the fault and transpressional deformation began during the late middle Eocene and continues to the present. Oblique convergence and clockwise rotation along the continental margin are the inferred driving forces for ongoing deformation. Evidence for Quaternary movement on the southern Whidbey Island fault includes (1) offset and disrupted upper Quaternary strata imaged on seismic-reflection profiles; (2) borehole data that suggests as much as 420 m of structural relief on the Tertiary-Quaternary boundary in the fault zone; (3) several meters of displacement along exposed faults in upper Quaternary sediments; (4) late Quaternary folds with limb dips of as much as ≈9°; (5) large-scale liquefaction features in upper Quaternary sediments within the fault zone; and (6) minor historical seismicity. The southern Whidbey Island fault should be considered capable of generating large earthquakes (M s ≥7) and represents a potential seismic hazard to residents of the Puget Lowland.

TL;DR: In this paper, the authors measured the deuteron T 1 as a function of water layer thickness for a carefully prepared series of hectorite-D 2 O samples and found that at room temperature, the surface effect on the rotational properties of water molecules is negligible.

24 Mar 1989TL;DR: In this article, a catalytic cracking process is provided featuring multiple risers (26, 27) in which a variety of hydrocarbon conversion reactions take place, a stripping unit (36), in which entrained hydrocarbon material is removed from catalyst and a regeneration zone (2) where spent cracking catalyst is regenerated, which comprises: a relatively high boiling hydrocarbon charge material (30) in a first riser (27) in the presence of a first catalyst component which is an amorphous cracking catalyst and/or a large pore crystalline zeolite cracking catalyst
Abstract: A catalytic cracking process is provided featuring multiple risers (26, 27) in which a variety of hydrocarbon conversion reactions take place, a stripping unit (36) in which entrained hydrocarbon material is removed from catalyst and a regeneration zone (2) in which spent cracking catalyst is regenerated which comprises: a) converting a relatively high boiling hydrocarbon charge material (30) in a first riser (27) in the presence of a first catalyst component which is an amorphous cracking catalyst and/or a large pore crystalline zeolite cracking catalyst to provide lighter products: b) converting an ethylene-rich charge material (88) introduced to a second riser (26) at a lower level thereof in the presence of a second catalyst component which is a shape selective medium pore crystalline silicate zeolite catalyst to provide heavier products and to increase the temperature of the catalyst in the region: and, c) converting a naphtha charge material (89) introduced to the second riser (26) at a higher level thereof in the presence of the second catalyst component to provide a relatively high octane gasoline product.

06 Sep 1991TL;DR: In this article, a rear contact construction on silicon solar cells comprises aluminum contacts with silver soldering pads, and the nickel is introduced into the contact construction to reduce the contact resistance between the aluminum contact material and the silver pads.
Abstract: A known rear contact construction on silicon solar cells comprises aluminum contacts with silver soldering pads. According to this invention, nickel is introduced into the contact construction to reduce the contact resistance between the aluminum contact material and the silver pads. In one embodiment, the nickel is applied as an intermediate layer (32) between the silicon substrate (2) and each silver pad (20). In a second and preferred embodiment, the nickel is incorporated into the silver ink that is used to make the soldering pads.
