Abstract: A truck bed extender is attached to a tail gate by mounting brackets. The mounting brackets attach to the tail gate only, and require absolutely no alterations to the truck bed. The truck bed extender may be easily removed by removing two pins or may be folded against the tail gate for minimum intrusion into the truck bed when the tail gate is closed. A telescoping back section may be adjusted for various truck bed widths. Corners of the truck bed extender are squared off to maximize use of the extended truck bed.

Abstract: A wheel frame for supporting at least two wheels along the bottom surface of a vacuum inlet nozzle of the type commonly used for vacuuming concrete floors of shops and other areas which have cement or wooden floors. The wheel frame is rectangular and has preferably two wheels held by the frame. The frame fits over the conventional vacuum nozzle and snaps over the flange at the bottom of the vacuum nozzle. The wheels are positioned so that they are near the back of the nozzle so that the front edge of the nozzle can be lifted by tilting the nozzle toward the back. This greatly facilitates the vacuuming up of leaves and other larger objects which do not fit under the front edge of the conventional vacuum nozzle.

Abstract: A process for disposing of solvent-containing liquids so that they do not contaminate ground water. An absorbent blend is mixed into a water-containing solvent mixture at the rate of about 1 lb. of blend per gallon of liquid. The blend is made up of a swellable polymer, consisting of polyacrylamide/polyacrylate co-polymer salt or poly 2-propenamide-co-2-propenoic acid homopolymer salt which swells and absorbs liquid. The blend also contains a mixture of solid absorbents. The resulting mixture is stirred in the container until it becomes thick and then it is allowed to set to provide a disposable modeling clay-like solid. The resulting solid material, after curing, may be then simply added to solid trash, and thus, be freed from contaminating ground water.

Abstract: A brake assembly for inline skates. The brake assembly has a braking roller which is turned by one or more of the wheels of the inline skate when the roller is in a braking position. The braking roller then expands outwardly and causes its outer surface to rub against a braking surface causing a braking action. The braking roller may be carried by a pair of carrier plates movably positioned within the frame which holds the inline skate brake wheels.

Abstract: A modular fuel dispensing and containment assembly for storing fuel in at least one fuel tank and for pumping the fuel to a group of fuel dispensers. The assembly has a reinforced concrete vault located underground which contains a fuel tank within its interior. The fuel tank is separated from the interior walls of the vault. The fuel tank has a turbine corridor on its lid, which corridor has an interior volume which leads from the fuel tank to a series of piping corridors. The turbine corridor and the piping corridors are all underground and the piping corridors lead to dispensing modules which are located under the dispensers or gas pumps. The dispenser modules and piping corridors are all sufficiently large to permit the entry of service personnel to their interiors. The interiors of the various corridors and modules form a single interconnected air volume.

Abstract: A water activated release triggering mechanism is removably held to an exterior surface of a buckle housing and includes at least two probes and at least two batteries distributed between independent paths, for firing a squib. The distribution of batteries between independent paths precludes false firing from a single short with the body of the housing. The triggering mechanism is designed to be impervious to Electro Magnetic Interference (EMI) and to preclude false release in the presence of 20,000 volts of Electro Static Discharge (ESD). The triggering mechanism may be easily removed for servicing, replacement, or for upgrading. In one embodiment, the triggering mechanism causes the buckle to release in the same manner as during manual release.

Abstract: A fitting for releasably constructing a structure from tubing. The structure may be a machine housing providing safety during machine operation, which housing requires removal for machine maintenance. The fitting includes a corner piece and at least two arms extending from the corner piece, each arm having a central axis and an outwardly extending slice through the arm separating a distal end of each arm into a first finger portion and a second finger portion. A threaded hole orthogonal to the central axis and centered on the slice, has tapered threads. A screw resides in the threaded hole, wherein the screw and threaded hole have cooperating threads (e.g., cooperating tapered threads). A tubing end is slid over the arm, and includes an access opening allowing access to the screw. The screw may be advanced into the threaded hole, thereby spreading the finger portions and locking the tubing on the arm.

Abstract: An earthquake actuated micro switch includes a ball which falls into a micro switch actuating position when disturbed. The ball normally resides in a shallow ball seat. A sufficient disturbance causes the ball to escape the ball seat, and fall into a switch seat. When the ball comes to rest in the switch seat, a lower surface of the ball pushes a micro switch actuator, thereby actuating the micro switch.

Abstract: A device for engine exhaust extraction improves engine performance and efficiency. The device includes outer and inner tubes sharing a central axis. The inner tube is held in place by supports connected between the inner tube and the outer tube, which supports have a fan-like orientation. Helically oriented vanes reside on an outer surface of the inner tube, which vanes extend outward. An inlet flow separates into an outer flow between the inner tube and the outer tube and an inner flow inside the inner tube. The fanblade-like supports and helically oriented vanes cause the outer flow to rotate about the central axis of the device. The flow recombine near the device outlet.

Abstract: A noise maker includes a face piece, a blow tube, and noise making tongue. The face piece may be a small planar representation of a face or of a portion of a face if a clown, monster, cartoon character, or the like, and may be made from cardboard or plastic. The blow tube extends inwardly from the face piece and the tongue extends outwardly from the face piece. The blow tube includes a tube passageway running the length of the blow tube, and the tongue includes a tongue passage running the length of the tongue. Blowing into the blow tube results in producing a raspberry noise at an opening end of the tongue. A lanyard may be attached to the face for carrying.

Abstract: A sealed liquid accumulator for accumulating a liquid in a box which is sealed to prevent the escape of odors from the interior of the box. The accumulator has an outlet tube for evacuating liquid from the interior of the box by way of a vacuum. A source of replacement air is supplied to the box through a controlled valve.

Abstract: A two-piece articulated snowboard having a first section held to a second section by a connector. the connector is configured so that it permits some bending so that the longitudinal axis of the board bends at the connector. Preferably, the connector permits very little or no twisting so that the first and second sections stay in the same horizontal plane.

Abstract: A back support apparatus having a pair of elongated, inflatable bladders which are spaced parallel to each other. The pair of bladders are vertically attached to a front panel of a backpack such that when the bladders are inflated by a pump, the user may experience cushioned back support on opposite sides of the user's spinal column, especially along the thoracic region.

Abstract: A brake assembly affixed to a skateboard. A brake drum is held to an inner surface of one of the wheels of the skateboard and has an outwardly facing braking surface. A brake pad is held between the underside of the board and the outwardly facing braking surface. A brake pedal extends through an opening in the skateboard. When the brake pedal is depressed, the brake pad moves downwardly and contacts the outwardly facing braking surface, thereby slowing the wheel to which the brake drum is affixed.

Abstract: An easily removable and replaceable toilet seat and hinge assembly. When it becomes necessary to clean the top of the toilet and seat and lid, a toilet seat and lid may be readily removed without having to remove the bolts which hold the seat and lid on the toilet. Instead, male and female clip members hold the seat to the toilet and may be readily snapped in and out of attachments to remove or replace a toilet seat and lid.

The drawing element is held above the surface of the viscoelastic solution and a portion of viscoelastic solution which has been drawn up with a drawing element falls slowly off of the drawing element to provide an entertaining and interesting display. Preferably, the drawing element has a horizontal bar which is slowly rotated into and out of the viscoelastic solution providing an ever-changing display.

Abstract: A surfboard having composite covered honeycomb deck and bottom surfaces. The surfboard has a hollow inner volume which contains a longitudinally oriented stringer. The stringer is spaced both from the nose of the surfboard and from the tail of the surfboard so that the nose and tail are more flexible than the length containing the stringer. The process of making the board is also disclosed.

Abstract: A parachute canopy release mechanism. The canopy release releasably holds a strap holding member. The strap holding member is released by movement of a latch, which in turn is released by an actuating lever which is protected against inadvertent opening by a cover. The cover has a cover lock which further prevents the inadvertent release of the latch. The release mechanism can have a removable triggering unit which is activated when the mechanism is exposed to water.
