Abstract: A battery system and method of operation are shown. The battery system utilizes a microparticle fuel slurry containing microparticle spheres surrounded by active electrochemical material. In the operation of the battery system, the microparticle spheres are attracted to battery-cell electrode plates and held there by a magnetic field. The core of the microparticle spheres and battery-cell electrode plates may be permanently magnetic or ferromagnetic in nature. The magnetic field may originate from permanently magnetic materials or be induced using magnetic field windings or the like. The battery system may be recharged by replacing spent microparticle fuel slurry with unspent slurry. In some applications, such as when used to power an electro-motive vehicle, a reserve of unspent microparticle fuel slurry may be stored on-board the vehicle and used to periodically replace spent microparticle fuel slurry during operation.

The surface will typically be a table, and the arms and restraining bar may be pivotally secured to the table by one or more sides that are pivotally secured to the table, so that the arms and restraining bar rotate about the same axis relative to the table. This axis of rotation of the arms and restraining bar may be disposed between front and rear ends of the table and above the table surface, so that the arms may extend substantially horizontally between the front end of the table and the axis.

Abstract: Automated hydroponic plant growing apparatus, for providing an equal supply of nutrient solution, at a controlled rate, to plants in each of a plurality of individual growth chambers, with provision of flow irrigation of each plant in each chamber. The apparatus provides for fully powered, pressurized flow of nutrient solution through separate lines to each growth chamber, and provides for automatic maintenance of equal levels of nutrient solution in the various chambers of the system, having return flow lines for return of any excess accumulation of nutrient solution from any one growth chamber to the central distribution chamber. Through provision of pressurized flow of nutrient solution to the growth chambers, the system avoids any need to rely even in part on gravity flow of nutrient solution, and so may be used with all components located on a single level, e.g. all resting on a common floor.

Abstract: An aircraft ice detection and de-icing system is disclosed in which an aircraft is positioned remotely from a laser beam generator, a beam of radiant energy is reflected from a mirror so that the beam impinges upon and creates a footprint upon a surface of the aircraft and the mirror is manipulated to move the footprint about the aircraft surface. The beam has a wavelength that is preferentially reflected by the aircraft surface and absorbed by ice, snow and water, so the beam heats and removes ice, snow and water from aircraft surfaces as the beam's footprint is moved thereabouts. A remote thermal monitoring system may also be used to monitor temperatures at the aircraft surface for detecting regions experiencing temperature rises at relatively increased rates as the regions are treated with the beam, thereby indicating the presence of ice, snow or water. A visible light may also be used simultaneously to track and indicate movement of the footprint of the treating beam about the aircraft surface.

Abstract: A stump cutting or grinding apparatus and method are disclosed which utilize a pump for attachment to a power takeoff of a tractor, a cutting or grinding device for attachment to a backhoe arm of the tractor, a motor connected to the cutting or grinding device, a plurality of lines for circulating hydraulic fluid between the pump and the motor and a plurality of lines for passing a portion of the hydraulic fluid through the hydraulic system of the tractor. Passing a portion of the circulating hydraulic fluid through a hydraulic system of the tractor enables the tractor to cool and filter the fluid and eliminates the need for a separate tank or reservoir that would otherwise be needed to contain and treat fluid being circulated between the pump and motor. A scoop may be attached to the cutting or grinding device for moving or removing rocks, dirt or debris from around the stump.

Abstract: An antimony recovery process is disclosed in which antimony-containing material is leached in a solvent including elemental sulfur and a caustic to preferentially leach antimony. The antimony-containing leach liquor from the leaching step is separated from the insoluble residue by filtration, and the antimony compounds in the separated leach liquor are crystallized to separate the antimony compounds from impurities which are left in solution in the leach liquor. The crystals are then redissolved and treated to create marketable antimony products of high purity, such as antimony metal, sodium hydroxy antimonate, sodium antimonate, antimony pentoxide, and antimony pentasulfide. Alternatively, the crystallized antimony compounds comprising primarily sodium thioantimonate crystals may be recovered and sold without further treatment. Waste products may be treated with soluble iron compounds and lime to render the waste products safe for disposal.
