Abstract: A conveyor assembly includes a support structure for a belt constructed of interlocking segments. The support structure includes straight segments that may be cut to any desired length. These straight segments are joined using a friction-fit connector. The connector does not require any drilling or other modifications to the straight segments. The straight segments may be constructed from a single sheet of stainless steel. The conveyor assembly may also include support arms, legs and other accessories.

Abstract: A switch operates between a first and a second position which selectively connects a load to a first and a second power supply. The connections are made by sliding one or more rods along their axis. The ends of the rods fit within channels to form electrical contact with the first and second power supply.

Abstract: A novel and efficient alkylation procedure of B—H-1,3,2-oxazaborolidines derived from ephedrine and norephedrine has been established. Representative B-butyl- and B-methyl-1,3,2-oxazaborolidines were prepared in good yield and excellent purity by one pot treatment of the parent boraheterocyclic compound with the corresponding organolithium reagent and subsequent hydrolysis of the cyclic borohydride with anhydrous ammonium chloride.

Abstract: A stable, wide-bandgap (approximately 6 eV) ZnO/MgO multilayer thin film is fabricated using pulsed-laser deposition on c-plane Al2O3 substrates. Layers of ZnO alternate with layers of MgO. The thickness of MgO is a constant of approximately 1 nm; the thicknesses of ZnO layers vary from approximately 0.75 to 2.5 nm. Abrupt structural transitions from hexagonal to cubic phase follow a decrease in the thickness of ZnO sublayers within this range. The band gap of the thin films is also influenced by the crystalline structure of multilayer stacks. Thin films with hexagonal and cubic structure have band-gap values of 3.5 and 6 eV, respectively. In the hexagonal phase, Mg content of the films is approximately 40%; in the cubic phase Mg content is approximately 60%. The thin films are stable and their structural and optical properties are unaffected by annealing at 750° C.

Abstract: The present invention is directed to an Fe(III) complex comprising a redox-active metal cluster in a chemically inert shell. The inventive complex has electron transfer and paramagnetic properties.

Abstract: A seismic switch is a programmable device capable of distinguishing between seismic movements due to an earthquake or an explosion, which is used to send a signal to control panels for security doors. The device uses accelerometers and a microcontroller for the detection and signal analysis of the seismic movements. In the event of an explosion or earthquake, the device produces a loud sound which serves as an audible alarm. Other proposed applications, with minor modifications to the device or software code, include monitoring of freight handling, emergency shut-off controller for industrial control systems and machinery, a by-pass system for electronic access control panels, and as a theft-deterrent or a component of a security system for automated teller machines and other valuable devices or items.

Abstract: A weed puller includes a handle, a pair of tines extending from the bottom of the handle, and a step extending back from the handle. The tines are pushed into the ground near a weed by pressing down (by foot) on the step. The handle is then pulled back. This causes the tines to pivot and lift the weed (and its root structure) out of the ground. The pivot occurs about the outer-most end of the step. The step is wider than the pair of tines so that the downward pressure on the step is distributed about a relatively large surface area. Thus, the entire step remains above ground, without breaking the ground below the step, to minimize the portion of the ground that is broken by removal of the weed.
