Abstract:
Deasphalted residual oil (DAO) and the aromatics-rich extract that is derived from DAO have low polycyclic aromatics contents, relatively low aniline points, and high flash points. They form blending stocks that improve properties of mixed feedstocks to consistently produce environmentally qualified rubber processing oil (RPO) by extraction under low solvent-to-oil ratios and moderate extraction temperatures. Distilling a petroleum crude oil under atmospheric pressure generates a bottom residual oil which is then subject to vacuum distillation to yield a bottom residual oil. DAO is produced by removing the asphalt from the vacuum bottom residual oil through extraction with light paraffinic solvent. The extract of DAO is a co-product in the production of the bright stock of the lubricating oil through extraction. The feedstock is mixed with the extract from a petroleum fraction boiling in lube oil range. Liquid-liquid counter-current extraction yields a raffinate stream; removal of solvent therefrom produces the RPO.
Abstract:
A method for searching a frequency band to locate a channel. The method includes the steps of setting an initial frequency and a first frequency step; determining a frequency point based on the initial frequency and the first frequency step; determining whether the frequency point satisfies a first condition, which is continuously detecting a horizontal signal a predetermined number of times. When the first condition is satisfied, the frequency point is recorded as an entrance point. A second frequency step based on the entrance point determines a second frequency point, wherein the second frequency step is less than the first frequency step. It is then determined if a channel exists at the second frequency point. The entrance point is recorded as the updated initial frequency for the next search. The described steps are repeated for the entire frequency band.
Abstract:
A portable device has lower and upper casings. A sliding hinge has a stationary frame attached to the lower casing, a sliding frame attached to the upper casing and a resilient positioning assembly mounted between the stationary and sliding frames. The sliding frame has multiple pushing pins protruding toward the stationary frame. The resilient positioning assembly has two sliders and multiple resilient elements disposed between and abutting the sliders. When the upper casing slides relative to the lower casing, the pushing pins move along and push corresponding sliders and pressing the resilient elements. As long as the pushing pins are moved to the other sides of the corresponding sliders, the resilient elements push the sliders back and the upper and lower casings of the portable device are open relative to each other.
Abstract:
An adjustable jig for retaining glass plate includes a frame, at least two clamp guides, and a plurality of clamp. The frame has a plurality of symmetric retaining component on two parallel frame columns. The clamp guide has a connecting portion for being retained by the retaining component on two ends of the clamp guide so that the clamp guide can be fixed across the parallel frame columns. The clamp guide has an approximated T-shaped guide on at least one longitudinal side of the clamp guide. The clamp has an approximated T-shaped groove and an approximated V-shaped groove. The T-shaped groove serves to be slid into the T-shaped guide so that the clamp is sliding along the clamp guide for clamping glass of any size or shape The glass will be firmly clamped by multiple clamps through predetermined positions without risk of breakage.
Abstract:
A sliding hinge is mounted between a cover and a body of an electronic device and has a bracket, a linking panel, a slide and a connecting wire. The bracket is attached securely to the cover. The linking panel is attached securely to the body and is mounted slidably on the bracket. The slide is mounted slidably on the bracket. The connecting wire is wound around a fulcrum of the bracket and respectively connects to the linking panel and the slide. The cable of the electronic device is mounted through the slide. When the cover slides relative to the body, the slide and the linking panel relatively move in opposite directions. Therefore, the cable is folded to keep taut.

Abstract:
A method for automated channel installation comprises the following steps. In step (A), a frequency scanning operation is executed to lock on to a frequency. In step (B), it is determined whether the frequency scanning operation is complete, if so, the process proceeds to step (F), otherwise, to step (C). In step (C), it is determined whether the locked frequency corresponds to a reserved channel number, if so, the process proceeds to step (D), otherwise, to step (E). In step (D) the corresponding reserved channel number is assigned to the locked frequency, and then proceeds to step (A). In step (E), the locked frequency not corresponding to the reserved channel number is stored in a caching table, and then proceeds to step (A). In step (F), an unused channel number is assigned to the frequency stored, if any, in the caching table.
Abstract:
A method for swapping channel configuration data comprises the following steps. A channel profile table comprising a first channel number and a first primary key for mapping to first channel configuration data, and a second channel number and a second primary key for mapping to second channel configuration data is established. The first primary key in the channel profile table is swapped for the second primary key.
Abstract:
A method of manually setting a channel within a frequency range. The method comprises the following steps. A start frequency and a surf direction are set, and then surf channels. When a target channel is found or a pause instruction is received, surfing pauses. An auto naming function is executed to obtain a channel name of the target channel. A user determines whether to keep the channel name in a channel list. Surfing is repeated until the entire frequency range is searched or a stop instruction is received.
