Abstract: A spirit level including an aluminum body having at least one unpainted leveling surface for placing on a surface and a bubble vial for indicating the inclination of the surface to the horizontal wherein an unpainted leveling surface of the at least one unpainted leveling surface is protected by a readily manually removable elongated protective strip.

Abstract: The present invention is directed toward portable visible light beam pointing devices for set out, marking, and other handyman purposes, and thumb pressure mounted fixtures fashioned as hooks, hook racks, wall mounts, and the like. The pointing devices include a light beam generator, and a pair of orthogonal bubble vials for indicating the orientation of the pointing device along orthogonal axes in a horizontal plane. The thumb pressure mounted fixtures have a body member and at least one thumb tack-like member with a central portion having a steel spike transversely directed relative to the body member for driving into a supporting surface. The thumb tack-like members are intended to be manually collapsible from an arc shaped inoperative configuration with a concealed spike to a generally M-shaped operative configuration with an exposed spike for driving into a supporting surface.

Abstract: A handheld seed planting device including a rule-like seed spacing member with two or more dibbers and a depth marker for facilitating seed planting in terms of the spacing between neighboring seeds and/or their seed planting depth. Dibbers preferably double up as depth markers but a depth marker may alternatively be implemented as a simple depth gauge for clipping onto a seed spacing member.

Abstract: A method that allows a space vehicle to determine navigation information represented by the contents of a state vector. The method includes the steps of intermittently receiving navigation signals, initializing the state vector with an estimate of the navigation information, and generating a predicted state vector that represents the predicted values for the navigation information after a predetermined time increment in the future. The method further determines whether a navigation signal has been received within a predetermined window of time from a navigation beacon. If a navigation signal has been received, the method updates the state vector and the contents of the state vector are propagated forward in time to provide an estimate of the navigation information after a predetermined time increment. In some instances, however, a navigation signal is not received within the predetermined window of time.

Abstract: A prepeg formulation comprising prepreg filament fibers unidirectionally aligned, and/or woven and nonwoven fabrics, a thermosetting matrix resin and a small amount of well dispersed inorganic whiskers in the resin, alone or in combination with extremely fine fibers of a thermoformable polymer having at least one of a T.sub.m or T.sub.g greater than about 300.degree. C. or no T.sub.m or T.sub.g and a decomposition temperature greater than about 300.degree. C. The preferred matrix resin is a blend of a thermosetting epoxy resin and an amorphous thermoplastic polymer having a T.sub.g greater than about 195.degree. C.
