Abstract: An abrasive deburring machine comprised of a plurality of individually controlled abrasive modules, each having a rotatable drum type brush with flexible bristles, the drum is mounted on a rotatable support with axis of rotation generally perpendicular to the rotational axis of the drum. Each support with brush and support drive are mounted inside of a housing therefore creating a module. Plurality of such modules can be combined in a desired configuration to form a deburring machine or finishing/polishing machine tailored to a specific geometry of the work piece or part to be deburred, finished or polished. Each drum and drum support, including its axial angular position are controlled independently, which for a pre-programmed movement of all brushes in order to conform to a complex shape of the part to be deburred, optimize the process of deburring and maximize the durability of abrasive brushes.

Abstract: A DC powered water/moisture monitor suitable for use in combination with a Christmas tree stand to detect a low water/moisture level is provided. The alarm device set forth has application in many other fields including farmland moisture monitoring, house plant, soil moisture monitoring, water tank level monitoring inter alia. The device includes an alarm, a casing, electronic circuitry and sensors/probes/electrodes for detecting moisture/water. The unit is an integral unit and combines all of these features in a one-piece waterproof assembly. The arrangement is, therefore, portable and can be readily employed in a variety of different environments.

Abstract: A writing instrument including a body having at its distal end a saddle portion in which a writing element, for example a ball, is placed, and a feeding element with a plurality of channels through which mixing components may pass for application to a surface by the writing element. The feeding element is configured with the body so that the body is rotatable about the feeding element. There is provided at least one opening or passageway in the body position between the feeding element and the writing element wherein the mixing of the components takes place.
