Abstract: An improved fuel additive formulation, method of use, and method of producing the fuel formulation are described. The improved fuel additive of the present invention comprises a mixture of nitroparaffins (comprising nitromethane, nitroethane, and nitropropane), and a combination of modified commercially available ester oil and toluene. The ratio of ester oil and toluene to nitroparaffin is preferably less than 20 volume percent, with nitroparaffins comprising the balance of the additive. A method of preparing and using the additive formulation is also provided.

Abstract: An advertising display mounting device is provided for attaching promotional displays, dispensers, or other objects to a price channel mounted on the edge of a grocery or other retail store shelf. The advertising display mounting device has first and second clips adapted to mate with the price channel of a grocery or other retail store shelf. The clips are forced into mated relation with the price channel by a locking slide. First clip is provided having a plurality of teeth. Second clip has a slot formed therein for accepting first clip so that first and second clips are oriented parallel to each other and to the price channel. A channel formed in second clip accepts a locking slide, also having one or more teeth for cooperating with the corresponding teeth on first clip. As locking slide is forced into the channel, first and second teeth mesh and move the first clip relative to the second clip to lock the mounting device in the price channel.

Abstract: A method and apparatus of reclaiming hazardous inorganic wastes to produce an environmentally benign abrasive for use in loose grain processes, as a coated or bonded abrasive, or as a polishing grain. A tough and useful abrasive, with a MOH hardness of 7 to 8, is manufactured from emission control dusts of the aluminum industry or sludges from other industries, and may include small amounts of lead and cadmium oxides as toughening agents. The abrasive particles are sized by air sifting or by water sedimentation separating methods.

Abstract: A mounting device is provided for attaching promotional displays, dispensers, or other objects to a shelf in a grocery or other retail store shelf. The mounting device has resilient first and second jaws that are forced into engagement with the shelf by a locking slide. In one preferred embodiment, first jaw and second jaw are oriented at slightly less a 90.degree. angle relative to the body of the mounting device. The body has a vertical slot into which a rack attached to the second jaw slides and a horizontal channel into which a locking slide is inserted to cooperate with the rack. The rack has teeth which mesh with cooperating teeth on a locking slide to move the jaws together. In addition, the body has, for example a price channel, to which an advertising or promotional display device such as a shelftalker, or other object can be mounted.

Abstract: An addressing device has an address generator (43), data wire (1), combined address and a supply wire (2) and ground wire (3) that form a cable (1,2,3). This cable (1,2,3) connects to multiple addressable units (14), containing switching means (13), that are connected to the data wire (1). Every addressable unit (14) comprises an address detector (12), which controls the switching means (8,13). The address generator (43) will issue a standardized signal, that will change a parameter by the influence of an impedance member (7) together with the cable length, so that after the commutation of the first switching means (8) and the information transfer via a second switching means (13), the same standardized signal can be used to select the addressable unit of the next cell.

Abstract: An adapter device is provided for varying the length of a ball point pen refill cartridge to enable the cartridge to be used in a variety of ball point pen housings. The adapter consists of a barrel which slips over the distal end of a refill cartridge and is securely connected to the cartridge by a channel formed in the barrel. The barrel comprises detachable sections which are removed as necessary so that the cartridge with the adapter attached barrel sections is substantially equal in length to the exhausted refill cartridge. The channel permits air to flow to the ink cartridge, enabling ink to be flow easily from the cartridge.

Abstract: An aortic graft and system and method for implanting the aortic graft are provided. The aortic graft comprises a substantially cylindrical graft material with attachment means which comprise a plurality of post and hook assemblies which are implanted with a double catheter system to penetrate the aorta wall above and below the aneurysm to provide firm attachment of the aortic graft and, thereby, exclude the aneurysm from the circulatory system.

Abstract: An improved athletic shoe sole of the type with annular cleating segments has an annular cleat set projecting from the main sole surface and disposed along a substantially circular path, the set having a plurality of cleat nodes each of which is arranged in a substantially abutting relationship to at least one adjacent cleat node. Each node has a distal end or tip spaced from the main sole surface and first and second edges on opposite sides of the distal end with proximal ends terminating on the circular path. Improved pivotability and traction characteristics are provided.

Abstract: A circuit for securing a power supply is provided. The circuit consists of an energy storage means for supplying current to a load. The energy storage means receives current from the power supply at first and second current levels. The first current level is greater than the average current necessary to supply the load and the second current level is less than the average current necessary to supply the load. The current level of the power supply alternates between the first and second current levels as a function of a comparator means and a switching means assuring an adequate supply of current to the load. The comparator means compares the voltage across the energy storage means to a reference voltage and actuates the switching means. Hence, the current supplied by the power supply is different than the current supplied by the energy storage means to the load and the electrical characteristics of the load remain undetectable from the radio frequency emissions of the power supply.
