Abstract: Example techniques involve selection of playback devices within a media playback system for outputting a media stream based on user input. An example implementation involves a controller causing a plurality of first representations of at least some of a plurality of playback devices to be displayed on a first portion of a display. The controller causes a plurality of second representations of at least some of one or more groups playback devices to be displayed on a second portion of the display, each group having at least two associated playback devices of the plurality of playback devices. The controller receives an input indicative of a particular group of the one or more groups and adjusts a selected status of the particular group. The controller also determines which playback devices are associated with the particular group, and adjusts a selected status of the playback devices that associated with the particular group.

Abstract: In an example embodiment, a system of lifting, lowering and rotating a display may include a housing, a rotator, and a hoist. The rotator may be configured to selectively rotate the housing such that a display functionally coupled to the housing is rotated. The rotator may include an anchor and a rotating portion. The anchor may be configured to be attached to an elevated surface. The rotating portion may be configured to be functionally coupled to the housing, and configured to rotate relative to the anchor. The hoist may include a member and a hoist motor. The hoist motor may be configured to selectively rotate the member such that a cable functionally coupled to the member is wound about the member when the member is rotated in a first direction, and the cable is unwound from the member when the member is rotated in a second direction.

Abstract: Tar sand and Gilsonite are preferably crushed together so that the Gilsonite overcomes the stickiness of the tar sand and the tar sand alleviates Gilsonite dust, the relative proportions and the character of Gilsonite being such as to produce an additive product for an asphalt, usually refinery asphalt, and a resulting modified asphaltic cement for paving purposes to simulate Trinidad Lake Asphalt. One embodiment of the additive composition of the invention results in an asphaltic cement that outperforms that produced by use of Trinidad Lake Asphalt as the additive, while a second embodiment of the additive composition of the invention contains additional tar-sand-extracted bitumen and the resulting asphaltic cement more closely matches the performance of that containing Trinidad Lake Asphalt as the additive. The invention includes a system for extracting bitumen from tar sand and in one form provides for adding Gilsonite to the extracted liquid bitumen so it will effectively solidify when cooled.

Abstract: A composition useful in copying and printing is described. In one embodiment, the composition comprises a purified fraction of uintaite and a thermoplastic polymer. Preferably, the composition comprises a maltene-enriched fraction of uintaite derived by solvent extraction, a thermoplastic polymer and a colorant. In another embodiment, the present invention is an electrophotographic method comprising the steps of generating a latent electrostatic image; developing said latent image with a toner comprising a purified fraction of uintaite; and fixing said toner. The present invention is also a printing ink emulsion comprising a maltene-enriched fraction of uintaite.

Abstract: A water-based drilling mud additive comprising a pre-blended combination of about 2 parts of high softening point uintaite, about 1 part of a lower softening point uintaite, about 1 part of causticized lignite, and a strongly lipophilic, non-ionic surfactant is disclosed. This composition decreases shale sloughing and borehole instability during drilling of wells.
