Abstract: Extraction devices and related methods are disclosed. Extraction devices disclosed may include a hopper, a piston, and an evaporation chamber. The hopper may be filled with a plant material and a solvent. The piston may be removably housed within the hopper so as to form a hermetic seal with the hopper. Once a solvent and extract mixture is formed within the hopper, a valve in the bottom of the hopper may be opened to allow the solvent and extract mixture to flow into the evaporation chamber via gravity. The remaining plant material may be compressed by the piston to remove any remaining solvent and extract mixture. The solvent may be evaporated in the evaporation chamber leaving a purified plant extract. Various types of plant materials may be used within the hopper. Various types of solvents may be used as well, including heptane and hexane.

Abstract: Apparatus include an atmospheric pressure glow discharge (APGD) analyte electrode defining an analyte discharge axis into an APGD volume, and a plurality of APGD counter electrodes having respective electrical discharge ends directed to the APGD volume, wherein the APGD analyte electrode and the APGD counter electrodes are configured to produce an APGD plasma in the APGD volume with a voltage difference between the APGD analyte electrode and one or more of the AGPD counter electrodes. An electrode can be integrated into an ion inlet. Apparatus can be configured to perform auto-ignition and/or provide multi-modal operation through selectively powering electrodes. Electrode holder devices are disclosed. Related methods are disclosed.

Abstract: This hauling tarpaulin can be deployed, loaded with refuse, moved and unloaded by a single person. A stored tarpaulin rolled about a mandrel is easily unrolled and filled with lawn refuse. The mandrel holds the tarpaulin flat on the ground despite wind. When the hauling tarpaulin is filled with refuse, the hauling line is pulled, causing the mandrel to rise up on its legs, and the sides to rise, forming a boat-shaped structure which engulfs the refuse. The hauling tarpaulin then is pulled by the hauling line to the refuse collecting point. At the collecting point the tarpaulin is restored to its flat form and the waste material unloaded.
