International Classification:

H04M 1/00

US Classification:

4555751

Abstract:

A mobile computing device is provided that includes a housing, a display screen, and a keypad. The housing includes a front face having a portion that has a contour. The contour may be is inwardly directed and be defined by at least a first gradient direction. The display screen is provided with the front face, apart from the portion that has the contour. The keypad includes a plurality of keycaps that extend outward from the front face. The keypad may be provided only on an occupied region of the portion of the front face that has the contour. A maximum angle formed by the occupied region of the front face relative to a horizontal reference that is coplanar with the display screen is greater than 20 degrees.

International Classification:

A61M 16/04

US Classification:

12820222, 422 85, 422 57

Abstract:

Tracheal tubes having an integrated calorimetric COindicator are provided. In certain embodiment, the integrated COindicator is selectively sealed from the remainder of the tracheal tube by a removable sterilization barrier. Also provided are COindicators that exhibit long lasting, breath-to-breath dynamic color change and are storage stable. The devices and compositions of the invention find use in a variety of applications, e.g. in emergent intubation of a subject. Also provided are methods of making the devices and compositions, as well as kits that include the devices and/or compositions of the invention.

International Classification:

B01D 3/00

US Classification:

422187

Abstract:

We provide a process to manufacture a base stock, comprising hydrocracking, separating, and dewaxing, wherein the base stock has a ratio of Noack volatility to CCS VIS at −25 C. multiplied by 100 from 0.15 to 0.40. We also provide a base stock made by a process, and a base oil manufacturing plant that produces the base stock.

International Classification:

C10M14514

US Classification:

508469

Abstract:

The invention includes a process of making a lubricating composition including: contacting a heavy mineral oil feed in a hydrocracking zone with a hydrocracking catalyst at hydrocracking conditions, whereby at least a portion of the heavy mineral oil feed is cracked; recovering at least one gasoline-range fraction and one bottoms fraction from the hydrocracking zone; passing a first portion of the bottoms fraction including not more than about 67 wt. % of the bottoms fraction to a dewaxing zone; and passing a second portion of the bottoms fraction including at least about 33 wt. % of the bottoms fraction back to the fuels hydrocracker for additional processing; and where the bottoms fraction has a viscosity at 100. degree. C. of less than about 4. 0; contacting the first portion of the bottoms fraction with a dewaxing catalyst under catalytic dewaxing conditions, where at least a portion thereof is substantially dewaxed; contacting at least a portion of the substantially dewaxed bottoms fraction with a hydrofinishing catalyst under hydrofinishing conditions, thereby producing a hydrofinished, dewaxed bottoms fraction; and removing from the hydrofinished, dewaxed bottoms fraction at least one light fraction including diesel or jet fuel range material, thereby leaving a heavy fraction including the lubricating composition having a naphthenes content of at least about 33 wt. %.

International Classification:

C10M14514

US Classification:

508469

Abstract:

The present invention provides for a lubricating composition including: a hydrocracker-derived, highly naphthenic, low viscosity index mineral oil; from about 2 wt. % to about 14 wt. % of at least one polymethacrylate polymer; and from about 2 wt. % to about 14 wt. % of a performance additive package. The hydrocracker-derived, highly naphthenic, low viscosity index mineral oil is prepared by: (1) passing a first bottoms portion including not more than about 67 wt. % of a fuels hydrocracker bottoms recycle stream to a dewaxing zone; and (2) passing a second bottoms portion including at least about 33 wt. % of the recycle stream back to the fuels hydrocracker for additional processing; and where the recycle stream has a viscosity at 100. degree. C. of less than about 4. 0; (3) contacting the first bottoms portion with a dewaxing catalyst under catalytic dewaxing conditions, where at least a portion of the hydrocracker bottoms is substantially dewaxed; and (4) contacting at least a portion of the substantially dewaxed hydrocracker bottoms with a hydrofinishing catalyst under hydrofinishing conditions, thereby producing a hydrofinished, dewaxed hydrocracker bottoms; and removing from the hydrofinished, dewaxed hydrocracker bottoms at least one light fraction including diesel or jet fuel range material, thereby leaving a heavy fraction including the hydrocracker-derived, highly naphthenic, viscosity index mineral oil having a naphthenes content of at least about 33 wt. %.
