Abstract: A firearm mounting plate assembly is provided. The firearm mounting plate assembly includes a firearm slide with a first side, a second side, and a top side. A recess defined by a first slide wall and a recess base surface is disposed on the firearm slide top side. The recess includes a rib. The firearm mounting plate assembly includes a mounting plate with a top surface, a bottom surface, a front side, and a rear side. The mounting plate includes one or more bosses. The mounting plate is configured to secure within the recess of the firearm slide.

Abstract: A method and apparatus for obtaining at least one normalized baseline spectrum for a processing volume of a processing chamber; calculating a distribution value of the normalized baseline spectrum; obtaining a plurality of normalized cleaning process spectrums; calculating a distribution function of the plurality of normalized cleaning process spectrums; comparing the distribution value to the distribution function; and determining an end point by identifying when the distribution function approaches the distribution value.

Abstract: A multi-grade engine oil composition meeting required specifications of manufacturers is provided. In one embodiment, the engine oil composition contains a sufficient amount of a Pour Point Reducing Blend Component for the engine oil to have cold crank simulator viscosity at ?20° C. of less than have a cold crank simulator viscosity at ?20° C. of less than 9000 cP and a mini rotary viscometer (MRV) viscosity at ?20° C. of less than 60,000 cP. The Pour Point Reducing Blend Component is selected from 1) an isomerized Fischer-Tropsch derived bottoms product; 2) a bottoms product prepared from an isomerized highly waxy mineral oil, or 3) an isomerized oil having a kinematic viscosity at 100° C. of at least about 8 mm2/s made from polyethylene plastic.

Abstract: A light-emitting structure of a decorative toy including a frame including an inner side wall and an outer side wall between which there is a groove provided with a plurality of partitions. A transparent upper cover is arranged on a top of the frame and a printed circuit board is mounted on a lower side of the frame. A plurality of light emitting members are at a circumference of the circuit board adapted to be located within the groove of the frame controlling means is electrically connected to the light emitting members via an electrical cord and provided with a loudspeaker and a switch. A translucent gem is filled into the groove of the frame to form a translucent region around a circumferential portion of the frame and to fix the printed circuit board within the frame. A bottom cover is fixedly mounted on a bottom side of the frame.
