Abstract: A route data base generating system avoids GPS satellite signals sources for land based vehicle azimuth and heading determinations in areas where reception of the satellite signals is unavailable or impaired and relies on vehicle part movements that are equitable to the heading and azimuth changes of the vehicle for determining such vehicle orientations. Part movements equitable to the heading changes are found in the vehicle wheel assemblies. A route data base founded on interconnecting linear route segments that are arranged in and end-to-end serial order is advocated and wherein the angular deviation between connecting segments in the order is predetermined. Various uses of the generating systems and related procedures are advocated for both on-the-road and off-road usage.
Abstract: A spear assembly for an underwater spear gun has an elongate shaft adapted to be fired from a spear gun and has a long axis, a forward portion, and a rearward portion. A tip member includes having front and rear portions with the tip member being removably attached to the forward portion of the shaft. An elongated cable has a forward end attached to the tip and a rearward portion attached to rearward portion of the shaft. Two barbs are included to improve operation of the spear. A rotatable rear cable restraint impedes movement of the cable and the tip member until the spear is fired from a spear gun. Another restraint means is also used for releasably securing the forward end of the cable to the tip member at a medial portion thereof. The assembly can also be used with pole spears and Hawaiian slings.
Abstract: A reduced material fastener has a shank cross-section selected to provide a parting line. Having a parting line means that the fastener may be made using two opposing dies, including roller dies, to cold form the cross-section. The cross-sections do not have to be symmetrical with respect to the parting line as long as hypothetical dies can be separated. Typical fasteners include common nails. Cross-sections having parting lines may have fin-like protuberances that result in less material being used for the same overall outline as a round cross-section. A computer aided design methodology and a nail making apparatus are also disclosed.
Abstract: A magazine doubler includes a resilient body with two cavities each having upstanding ribs to carry magazines therein at different heights. A bracket and spaced screws are mounted medially between the front and back of the body to squeeze the body to generally conform it to carried magazines therein. A blocking element is used to replace the top round in one magazine to prevent the upper round from being dislodged during use of the doubler. Such element is tethered and biased by a rubber band looping around one of the screw shanks.
Abstract: System and method for a continuous process for separating particles according to their magnetic properties such as Curie point includes a feed of hot particles having different magnetic properties on a moving surface spaced above a stationary magnetic assembly. The temperature of the bed of particles is controlled to enable selective separation of different factions of particles based upon the temperature of the particles. The magnets are maintained substantially below their Curie point. Gaseous nitrogen is fed into and from the inside of the magnetic assembly to enhance the cooling of the magnetic assembly and to inhibit oxidation. The gas exits through high temperature bearings to inhibit debris therein. A thermal shield is placed between the moving surface and the magnets and below tubes carrying a cooling fluid to maintain magnets substantially below their Curie point. The entire process is contained with an inert gas-purged cabinet.
Abstract: Making a spear gun shaft includes selecting a solid steel drill rod of desired length; wrapping the rod with thermo-setting polymer impregnated carbon fiber sheet; covering rod with compression wrapper; curing the resin coated rod in an oven; removing the covering; machining the cured resin to the desired diameter with ends exposing drill rod; affixing a spear tip-carrying member to an end of the rod; affixing a trigger-engaging member to opposite end of the rod; affixing collars over the joints formed between rod and members to reinforce the shaft at the respective joints; mounting a sliding collar onto rod; and affixing the collars with metal adhesive to waterproof and seal the respective joints covered by the collars.

Abstract: A mobile clean room has a substantially rectangular frame having an upper and lower portion and is formed of a plurality of metal tube members and transparent plastic wall panels affixed to the frame to form an end wall and front and rear walls. A floor plate is affixed to the lower portion of the frame. A plurality of locking swivel wheels is affixed to the lower portion of the frame. A ladder is mounted between the floor plate and the upper portion of the frame. A dust guard assembly is attached to the top of the frame and is movably mounted. A door is pivotally mounted to the frame.
Abstract: An adjustable and removable rail light mount for attachment to a firearm having a mounting rail includes a rail mount attached to a rail and a light carrier rotatably attached to the rail mount to position a light to the left or right of a firearm by way of an axle carried by the rail mount. The axle fits through the rail mount and the light carrier. Passageways in the rail mount and the light carrier for the axle include grooves that engage detent bosses on the axle to maintain the light carrier in the selected location. Light carrier is removable when it is rotated to a centered downward position.

Abstract: A boat lifting assembly includes a cradle for carrying a boat mounted between three pilings on each cradle side. A pair of support housings is affixed to the pilings on each cradle side. A pair of hydraulic lifts are housed in the housings and connected to the cradle for moving same vertically. Each lift includes a horizontally extensible piston carrying a piston pulley block and a stationary hydraulic cylinder. Three cables have one end portion threaded between the pulleys of the block and the cradle. Transition pulleys are supported by the housing and direct the cable vertically for moving the cradle when the block is moved. Additional pulleys and various anchor points may be employed to provide for vertical lifts of 1.5, 2.0 and 3.0 times the distance of movement of the piston. The housings are in the same plane as the cradle deck and/or dock.
Abstract: A seat belt receiver attachment includes an elongate connection member removably mountable closely adjacent a seat belt receiver and a planar flexible shield member having an inside surface locatable adjacent a holster worn by a user with the outside surface being adjacent a seat belt receiver. The shield member and connection member include spaced side edge portions and a plurality of pairs of spaced mounting holes and may include a pair of spaced ears having mounting holes therethrough. Elongate straps are threadable through the mounting holes to secure the members together. A releasable fastener attaches the members together for assembly positioning.
Abstract: A net holder for carrying a landing net has an upper housing in the form of a channel member with a downwardly disposed opening hinged at its rearward portion to the rearward portion of a lower housing in the form of a channel member slightly narrower than the upper housing with an upwardly disposed opening. The hinge is spring-biased to force the upper housing downwardly onto and over the lower housing to enclose a landing net therein. The front of the lower housing has a notch into which a handle of a net can be inserted and thereby secured. The holder can be attached to the inside or outside of a boat by any appropriate fastener.
Abstract: A divided storage system is formed of a collapsible container and a collapsible divided file assembly. The container includes a planar blank having a centrally-located bottom panel with four side portions, four side panels each foldably attached to a respective one side portion and movable to a position perpendicular to the bottom panel fasteners are carried by each side panel for attaching the side panels together to define an interior space. The file assembly includes files each locatable adjacent to the side panel and removably attachable thereto.
