Abstract: Described herein is a combustion process waste receptacle having a fluid lock that has an open state (in which fluid contaminants can pass into a fluid contaminant reservoir) and a closed state (in which fluid contaminants are prevented from entering into a fluid contaminant reservoir). The fluid lock preferably transitions from the open state to the closed state when the fluid contaminant reservoir is full. The fluid lock preferably includes a float chamber and a floatable float.

Abstract: An outdoor power equipment having sitting configuration and standing configuration is presented herein. The outdoor power equipment can be transformed from the sitting configuration to the standing configuration and vice versa, allowing an operator to use the outdoor power equipment in either a sitting position or standing position. The sitting position can place the operator at least in part forward of a drive axis of the outdoor power equipment, whereas the standing position can place the operator at least in part coincident with or behind the drive axis. The outdoor power equipment can be electric powered in some aspects, with modular and replaceable battery packs.

Abstract: A process for forming a three-dimensional article in sequential layers in accordance with a digital model of the article. The process comprises the steps of defining a layer of powder material, applying a liquid reagent to the powder layer in a pattern corresponding to the digital model, and repeating these steps to form successive layers. The powder comprises a first reactive component and the liquid includes a second active component capable of reacting with the first reactive component so that the article is built up in layers.
