Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a process of manufacturing a product. In one aspect, the method comprises repeatedly performing the following: i) selecting a configuration of input settings for manufacturing a product, based on a causal model that measures causal relationships between input settings and a measure of a quality of the product; ii) determining the measure of the quality of the product manufactured using the configuration of input settings; and iii) adjusting, based on the measure of the quality of the product manufactured using the configuration of input settings, the causal model.

Abstract: The present invention provides a sander vacuum nozzle attachment also known as a dust wing adapter that captures dust while sanding by attaching to a sander and a vacuum system. It comprises of a hollow body with a central intake aperture that attaches to the dust bag mount of the sander and an outlet aperture that attaches to the suction hose of the vacuum system. The device also features a pair of wings that are placed adjacent to the sanding head and to the work surface, each wing has multiple wing intake apertures which allow dust to be drawn into the hollow body by the vacuum system. The design is efficient and compatible with orbital sander and mouse sander, and the shop vac is used as vacuum system.

Abstract: A pellet burner has inner and outer housings for defining a high pressure air plenum between. Angled perforations at strategic locations in the inner housing supplied pressurized primary and secondary combustion air so that, with pellets supplied to a burn pot of the inner housing and activation of a blower and an ignitor cartridge, the pellets auto-ignite and the air flow establishes a swirling flame in the burn pot that travels to a flame conduit of the inner housing where further swirling occurs in a venture section for shaping the flame into a clean, hot, symmetrical form.
