Abstract: A terrestrial magnetism responsive device adapted to use a north or south seeking magnet in both north and south headings, the device including a housing having a north or south seeking magnet therein, the magnet being suspended adjacent one pole by a sensitive spring to permit the magnet to be movable horizontally, when released, from a north pointing position or a south pointing position. The method includes the releasing of a north or south seeking magnet in the housing so that it is free to move easterly or westerly on the spring, moving the housing over the areas to be explored, and recording the east/west diversions of the magnet and the exact locations of the diversions.

Abstract: An anemometer for measuring the component of air or of a similar fluid speed along its axis of rotation, in which the anemometer has a plurality of generally radially directed, helicoidal airfoils. The airfoil effect is produced by the helicoidal twisting which results in a vacuum being produced on one side thereof according to the direction of rotation. Each of the airfoils has a plurality of helicoidal edges, each edge being formed by the intersections of two or more plane surfaces so as to form airfoils having parallelogram or substantially parallelogram cross-sections. Each airfoil extends outwardly from a rotatable hub and is attached to the hub at its inner end but is spaced in part from the hub by a cutout area, such as a slot across the airfoil.

Abstract: A self watering apparatus for home growing bean sprouts includes a housing divided into an upper compartment and a lower compartment by a horizontally positioned divider plate provided with orifices. An open top sprout container tray is placed within the lower compartment of the housing, the bottom of the sprout containing tray is provided with a drainage opening. A tilting water container is pivotally mounted in the upper compartment of the housing, the tilting water container has an established capacity and collects water from a water supply line at a controlled rate. Each time the volume of water collected in the tilting water container reaches the established capacity, the tilting water container discharges the collected water on the divider plate and drains through the orifices into the open top sprout container tray.

Abstract: The present splitting saw generally comprises an elongated housing one end of which generally constitutes a drive end and the opposite end a driven end for an endless saw blade. The drive end mounts an electric motor connected by gearing to a drive pulley around which the drive end of said saw blade is trained, and the driven end is provided with a takeup pulley over which the opposite end of the pulley is trained.Both the drive and the driven pulleys are provided with radially and uniformly spaced drive pins, and the saw blade is provided with apertures that are spaced to receive the outer ends of said drive pins thereby effecting drive connections between the drive pins and the pulleys and the apertures in the saw blade.

Abstract: An illuminated position indicator for a control shift lever in which the shift lever housing has an associated dial with viewable character indicia thereon representing the respective driving range positions of the shift lever, the dial being associated with a light source providing a general illumination of all the dial indicia, and wherein a lens positioned between the dial and light source provides a concentrated beam for intensified illumination of the indicium corresponding to a selected position of the shift lever, a connection with the shift lever being such as to provide relative movements between the light beam and dial in response to shifting movements of the shift lever. In a modified arrangement, the dial indicium is visually intensified by colored backing member that is moved rectilinearly below the dial in response to selective movements of the shift lever.

Abstract: A high performance portable knockdown boat structure having one or more unique inflatable hull structures in the form of a relatively low pressure envelope which tapers from its mid-length to its opposite ends, and is provided with a sectionalized light weight reinforcing tubular member which can be inserted endwise into a longitudinally extending surface sleeve. The reinforcing member is easily inserted into the sleeve when the envelope is deflated, and upon inflation of the envelope will be retained and anchored against removal. The unique envelope may be readily embodied in boats of the single hull type with or without an outrigger, as well as in boats having more than one hull, and particularly to provide a unique, lightweight, high performance catamaran.
