Abstract: An inboard-motorboat-engine flusher has an inlet enclosure (1) with a means for attachment (5, 6, 11, 16) to a bottom (3) of a boat (4), a conduit (7) in fluid communication between an outside and an inside of the inlet enclosure, and a hose connector (8) on the conduit.

Abstract: A cargo submarine has a cargo section (2) between tapered peripheral buoyancy sections (2-5) and an on-board cargo-handling components (32-49) capable of rapid loading and unloading of large volumes of cargo. A hydrodynamic tower (14) conveys fresh air in and exhaust gasses out while traveling submerged sufficiently deep to avoid wave undulation. Dual electronic controls (51-57) in a tower bridge (27) and in a main bridge (50) are provided for large vessels. A crane (32) with automatically-adjustable weight balancing and electronic controls is telescoped from within the vessel. A shore ramp (47) and a ship ramp (44) are provided for fast and convenient motorized or manual handling of commercial or military cargo at beaches and shores without docks. Special hydrodynamic configuration and contouring result in less drag-per-length coefficient of marine vessels, resulting in less ton-mile propulsion costs than for optimized displacement-hull ships.

Abstract: A method for accomplishing the above and other objectives has steps of applying a mild solution of acid to surfaces of grout and tile, letting the surfaces dry for approximately 12 hours, applying a grout colorant and sealing material, referred to as grout-treating material, to the grout and such surfaces of tile as the grout-treating material contacts in an application process, allowing grout-treating material on grout and tile surfaces to dry, cleaning the grout and tile surfaces with a non-solvent cleaner and then merely scraping and vacuuming or sweeping the grout-treating material from the surfaces. A small portion of the grout-treating material which might stick to surfaces of some types of tile in the event of errors in applying this method can be scraped off easily or removed with a scrub pad. The preferred acid is 3-to-15 percent oxalic acid in a solution with water. Similar proportions of muriatic acid or sulfanilic acid can be used as substitutes for oxalic acid.

Abstract: A speed selector (24, 25, 40) actuates a computer (32, 35, 38, 39) to calculate optimum engine speed, speed-change rate and gear ratio for achieving a selected speed of a motor vehicle (18). An actuator (36) then accomplishes throttling of an engine (19) with a throttling means (20) and gear changes of a transmission (21) as necessary to achieve the selected vehicle speed with least-possible fuel consumption and exhaust smog. When a desired change in speed is made, it is maintained in a cruise-control mode with optimized rates of change of throttling and gear-shifting for necessary changes in engine speed for varying terrain and driving conditions.

Abstract: A waterproof closure seal (20, 22) for closing openings on bags, pockets and other items having two components, a male (2) and female (1) component. The male component (2) has a planar base (12) with a wide insert having indentations (10a, 10b) on each side which fits into a cavity (8) on the female component (1) when pressure is applied on the outside of both components (1, 2). The female component (1) has legs (7a,7b) on each side of the cavity (8) with hooks (6a, 6b) which fit into the indentations (11a, 11b) on each side of the male insert (3) to better grasp the insert. The female component (1) may have one or more ribs (14) extending from it which fit into matching grooves (15) on the male cavity (2) to form an even better seal. An elastomeric overlay (16) can be molded on the male insert (3) to better maintain the seal even in extreme temperature conditions. The male and female component may be attached to each other at one end and used to seal a bag, such as a potato chip bag, to preserve freshness.

Abstract: A sectional folding table has a first-tabletop frame (3) with an outside periphery into which a second-tabletop frame (4) and foldable legs (16, 18) of the second-tabletop frame are pivotally foldable. An attachment side (20) of the first-tabletop frame is attachable to a separate structure such as a vehicle compartment (15), to another table or to other desired objects of a desired height as an option to primary legs (26, 27). Legs of both tabletop frames are attached pivotally to a joint side (10) and positioned in juxtaposed relationship for side-by-side pivotal folding. Several embodiments are shown.

Abstract: A fish dehooking device is provided with a rigidly holdable T-shaped handle and a long rod with a smoothly-bent angled section at the opposite end for removing fishhooks from any depth within a fish. An optional enlarged spreader section of the rod is provided as a wedged base for removing the fishhooks and for preventing dislodged fishhooks being removed from puncturing intestinal sections or air bags that would lower the quality of the meat of the fish. The enlarged spreader section also allows fishhooks to be removed from the mouths of larger fish that have strong jaws and dangerous teeth. A method of using this device allows the holding and placing of hooked fish without contacting the fish or sharp projections on some types of fish.
