Abstract: A method and device for removing pollution from polluted water, consisting of a rod on which are mounted an array of spaced magnesium plates and an array of spaced copper plates. The copper plates are in contact with the magnesium plates. Polluted water passing through the plates results in precipitates of the pollutants which can be mechanically removed.

Abstract: A tool for installing an underground pipeline below an existing structure such as a sidewalk or driveway. The tool consists of a steel casing, an auger within the casing, a soil drilling bit at the end of the auger, and an hydraulic motor for driving the auger. A selected length of plastic or steel pipe is slid onto the casing before drilling. After the drilling is completed, the casing, auger, and auger bit are withdrawn from the soil, leaving the pipe length embedded in the soil.

Abstract: An optical element providing greater conversion efficiency and comprising a pyramid having a square base and four triangular faces of equal size and shape meeting at the apex. The optical element can also comprise an octahedron or double pyramid of similar configuration.

Abstract: A device for locking a brake pedal in depressed condition, comprising a first tube, and a second tube concentric and slidable in said first tube; said first tube having brake pedal engaging means; said second tube having steering wheel engaging means; said device having spring actuated button means for extending and locking said tubes together in selected positions.

Abstract: A portable, removable rear cover for an electric golf cart in the form of a flexible, thin, lightweight, weather-resistant sheet. The sheet has an upper, transparent plastic panel and a lower, woven fabric panel. Shock cords are provided for attaching the sheet to both the upper and lower portions of a golf cart frame so as to cover golf clubs stored in the well of the cart. Grommets and loops are provided in the upper portion so that the cover can be used with more commercially available golf carts.

Abstract: This device comprises a folding seat for walkers. It is inexpensive, easily removable, installable, and storable. It comprises an elongated, flexible sheet whose ends can be bent over and under the side bars of a walker and connected together underneath to form a seat by lace and eyelets. By adjustment of the spacing or overlap of the ends, the height of the seat from the floor is adjustable.

Abstract: An easily removable and reusable cable strain relief device for accommodating and fastening a cable in a socket hole in an instrument wall. The head section (2) has a collar (3) which lies flush against the outer edge of the socket hole (8) and a shaft (4) with U-shaped catch lugs (5) and (6) engaging the inner edge of the socket hole (8) and pressing against the cable (14). Cable lug (5) is externally accessible for pivoting so as to disengage the device from the socket hole.

Abstract: An improvement for a cable terminal which includes a terminal carrier 1 and a terminal clamp 12 tracked in the carrier where a flexible locking tooth 8 on the terminal carrier 1 works in conjunction with a toothed rack 24 on the terminal clamp 12. In this improvement the terminal carrier 1 is in the form of a hollow cylinder or cuboid whose upper edge includes two opposed grooves 2, 3 to accommodate a cable, and the terminal clamp 12 includes a clamping rib 19, 20, 19a, 20a which acts on the cable from above and/or laterally, centrally to the grooves, and which can be axially displaced and locked.

Abstract: An improved, personal, submersible marine vehicle with a fluid-tight elongated hull having an open back and a removable cover. Within the hull is a battery compartment. A shrouded propeller and motor depend from the hull. A dense, rigid cellular foam section fills substantially all of the air space in the hull and surrounds the battery compartment. Electrical speed control means for the motor are embedded in the foam section so that the battery is shielded from contact with any source of spark in the electrical control means. Further, the foam section provides a substantially greater effective hull thickness than the actual thickness of the hull so that the vehicle can be safely used at far greater depths. Also, the foam section renders the vehicle substantially leak-proof.

Abstract: A novel lifting device for small craft in which the mechanism includes an hydraulic pump and an hydraulic cylinder pivotally mounted on a first horizontal shaft of a support attached to a boat or stationary surface. A first arm is mounted on the first shaft, and a second arm mounted on a second lower shaft. The piston rod of the cylinder is pivotally connected to the lifting platform. The other end of the first arm is pivotally connected to the lifting platform at a higher position than that of the piston rod. The other end of the second arm is pivotally connected at the same position as the piston rod. When the piston rods are extended, the platform is lower; when the rods are retracted, the platform is higher.

Abstract: A sanitary animal-waste container suitable for installation in public places. The container has a cover and an interiorly-mounted roll of detachable plastic waste bags accessible through a cut-out in the container.

Abstract: A decorative boot having interchangeable tubular decorative components adapted to lie substantially smoothly on the outer surface of the boot between the top of the boot and the ankle portion so as to leave the heel and toe portions uncovered.

Abstract: A lubricating oil purifying device adapted to be installed in the flow line of lubricating oil passing into an oil filter, comprising a solid body made of acid-reactive material and having a central orifice in which a coupling ring is positioned.

Abstract: A device for storing and retrieving one or more drumsticks, comprising in combination: a casing open at its top and defining a cavity, a drumstick support movable within the cavity in opposition to a first spring into locking engagement with a second spring, and trigger means for releasing the second spring; said device being characterized in that releasing the second spring causes said drumstick support means to move upwardly ejecting said drumsticks.

Abstract: An integral combination of column and pile for use in building structures in a sandy soil. The method of formation is to provide a ground situs of suitable depth and width formed preferably by an hydraulic-powered auger. The situs is then filled with a cementitious slurry. A reinforced precast concrete column is provided having reinforcing bars extending a substantial length out of its bottom. The exposed bars are inserted into the slurry until the column merges with the slurry. Upon the hardening of the slurry, the result is an integral column and pile set into the ground.

Abstract: A device for diffusing chemical animal repellent, comprising a container having a ground engaging pin, a sloping cover, and orifices permitting diffusion of chemical animal repellent in the container to the outside atmosphere.

Abstract: A hyperbolic paraboloid roof structure which has in combination rectilinear panels (10) tangentially attached to a frame of beams (11) each of whose top surfaces (11a) is a semicircular arc or segment thereof. The panels are assembled from prefabricated rectilinear subpanels (13).

Abstract: An intraocular lens surgically positioned in the anterior chamber and to be used in addition to the natural lens to correct the refraction. The lens is fixated by iris stromal support, comprising an optical portion of inner concave and outer convex shape and a side support portion which has one or more pairs of pincerlike extensions for holding a portion of iris tissue. The design provides safe clearance away from the vital structures both anteriorly and posteriorly. This technique of stromal iris support permits full pupil motility. Lack of any postoperative decentration allows the system to be used for myopia, hyperopia, presbyopia or astigmatism. A non-transparent, light-impermeable ring may be incorporated to prevent glare or edge effects. The lens provides high predictability of the precalculated optical power.
