Abstract: An apparatus for cosmogenic neutron sensing to detect moisture includes a thermal neutron proportional counter. A housing is formed at least partially from a moderating material, which is positioned around the thermal neutron proportional counter. A proportional counter electronics unit is within the housing and has a preamplifier and a shaping amplifier. The preamplifier and shaping amplifier are directly connected to the thermal neutron proportional counter. At least one photovoltaic panel provides electrical power to the thermal neutron proportional counter. A data logger is positioned vertically above the thermal neutron proportional counter and proportional counter electronics unit. A signal from the thermal neutron proportional counter is transmitted through the proportional counter electronics unit and is received by the data logger. The signal indicates a moisture content within a measurement surface of the thermal neutron proportional counter.

Abstract: A tool for twisting of the bare ends of electrical wires or conductors or connectors while simultaneously restraining rotation of wires at a predetermined distance from their bare ends. The tool reduces repetitive motion of the user when making electrical connections and can also enables the user to make more secure electrical connections. The various embodiments illustrate the invention as a hand tool or in conjunction with a power tool.

Abstract: An improved hitch assembly is described for mounting accessories while simultaneously towing a trailer. Examples of accessories include a fishing rod holder, a bicycle rack, a bridge, platform, and so on. The invention also includes a retrofit device for mounting accessories on existing hitches and an adapter device for mounting accessories on vehicles with wide bumpers.

Abstract: An apparatus for microline-by-microline illumination and scanning of a planar original has a number of spaced illumination elements, each having longitudinal and transverse dimensions substantially corresponding to a microline, and a number of spaced light-receiving elements disposed perpendicularly with respect to the microlines and corresponding to the number of desired picture elements along a microline to be scanned. Each light-receiving element at least partially overlaps a microline. The illumination elements and the light-receiving elements are respectively disposed in parallel planes in a common film. Structure is also provided at each overlap of a light-receiving element with a microline for coupling light from an illuminated microline to the light-receiving element.
