Abstract: A method to create, distribute and install on an installation computer a uniquely customized instance of a software application that is authenticable and traceable to a particular user. A secure distribution agent resident on a distribution computer collects identifying information, and calculates a cryptographic signature of the software application and identifying information. The identifying information and cryptographic signature are embedded in the software application by the secure distribution agent. The software application with embedded data is transmitted via a distribution channel to the installation computer. A user installation agent resident on the installation computer manages the installation of the software application with embedded data on the installation computer. Prior to installation, the user installation agent may use the cryptographic signature to verify that the software application, and the identifying information are authentic and have not been tampered with.

Abstract: Method for removing an oil filter from an engine when the filter is to be replaced or removed and apparatus for assisting such oil filter removal. An air valve is positioned on the casing of the oil filter and air is injected into the volume of the oil filter surrounding the internal filter. The air displaces oil in the oil filter. This reduces the quantity of oil in the oil filter and, after the air chuck and compressed air line are removed from the air valve, allows the oil filter to be removed without dripping oil on the floor of the garage or on the operator performing the servicing of the oil filter.

Abstract: An improved endoscopic system for visualizing subgingival dental procedures. The device comprises a dilator projection incorporated into or onto the body of a dental instrument utilized to remove plaque and calculus from subgingival tooth surfaces. The projection preferably comprises a thin, flat shield portion having an arcuate shank portion extending therefrom. In use, the shield portion of the dilator projection is operative to dilate or spread the gingiva away from the adjacent tooth surfaces upon which the dental instrument is utilized to remove plaque and calculus. Formed within the shank portion of the dilator projection is at least one lumen for receiving an endoscopic viewing apparatus, that receives and transmits an optical image from the interior of the gingival sulcus or periodontal pocket to an image displaying device positioned outside the patient's body. Additional lumens may be formed within the shank portion of the dilator projection for the infusion of fluid or suction/aspiration.

Abstract: A rearwardly swinging operator enclosure is provided for a skid-steer loader having vertical lift arms. The enclosure, as well as the links coupling the lift arms to the loader are both pivotally mounted high on laterally spaced apart support posts carried at the rear of the enclosure. The raised pivotal mountings permit the enclosure to swing rearwardly and high above the loader components housed beneath the enclosure to allow maintenance activities to be conveniently carried out from the front of the loader. The raised pivotal mountings further permit the use of a cross member to reinforce both the support posts and lift arm links and yet avoid interference with swinging movement of the enclosure or lift links. With the cross member positioned near the top of the support posts, rear visibility is enhanced.

Abstract: A skid steer loader control linkage engageable by an operator for controlling speed and direction of the vehicle. The control linkage operatively engages a roll over protection structure that is shiftable between a lowered operating position and a raised position whereat vehicle compartments are exposed for access by the operator. The engagement of the control linkage against the roll over protection structure shifts the control linkage between an operative position and an inoperative position as the roll over protection structure shifts between the raised and lowered positions.

Abstract: A rapidly solidified amorphous metallic alloy is composed of iron, boron, silicon and carbon. The alloy exhibits in combination high saturation induction, high Curie temperature, high crystallization temperature, low core loss and low exciting power at line frequencies and is particularly suited for use in cores of transformers for an electrical power distribution network.

Abstract: This invention is based upon the discovery that the characteristics of toner resins made by emulsion polymerization can be improved by utilizing diacid cycloaliphatic emulsifiers in the synthesis thereof. Toner resins which are made utilizing such diacid cycloaliphatic emulsifiers do not exhibit significant electrical charge effects from the residual level of soap in the resin compared to resins made using standard soaps; such as, rosin acid soaps and fatty acid soaps. They also generally contain a lower level of ash since salts do not need to be used in their coagulation. As a result of the low level of ash, the toner resin made from the diacid soap exhibits excellent resistance to moisture sensitivity and adsorption. This feature gives the toners made from these resins better electrical charge stability compared to resins made from conventional soaps since adsorbed moisture is known to neutralize electrical charges. Toners made from these resins also exhibit greatly improved adhesion to paper.

Abstract: A system and method reorder instructions for effecting faster branch execution. A processor element is coupled to receive stored instructions in a first order, and to process the received instructions in a different order, the processing occurring after each stored instruction of a first type is issued, and after a delay time, after each stored instruction of a second type is issued. The delay time is based on a delay value associated with the second type of instructions. In particular, the instructions include branch and non-branch instruction wherein firing time information identifies a time of execution of the branch instruction which is a variable number of instructions cycles prior to a time of execution of a last to be executed instruction in a basic block. Accordingly, branch instructions can be completely executed no later than during the processing of the last to be executed non-branch instruction in the basic block thereby speeding up overall processing of the software program by the system.

Abstract: A combustion assembly, particularly for a gas turbine engine, comprises a unitary baffle disposed in an axial inlet opening of a flame tube, which baffle has a plurality of air admission apertures extending therethrough and a plurality of fuel spraying devices mounted thereon. Each fuel spraying device includes a body having co-axial air and fuel passages therein, these passages communicating with outlet passage in the body through which, in use, a mixture of air and fuel is ejected. The fuel spraying devices are mounted on the baffle so that the outlet passages are disposed on a downstream side of the baffle, and also the fuel spraying devices are disposed between the air admission apertures to ensure substantially uniform mixing of the said mixture of air and fuel and air passing through the apertures in use.

Abstract: A large scale integrated (LSI) array of standard cells arranged in rows and columns adapted to receive different metallization patterns for producing custom circuits. Disposed in one half of each cell is a first power contact and contacts for the sources, drains and gates of field effect transistors of one conductivity type. Disposed in the other half of each cell is a second power contact and contacts for the sources, drains and gates of field effect transistors of complementary conductivity type. The pattern formed by the contacts in one half of a cell is the mirror image of the pattern formed by the contacts in the other half of the cell. The symmetry of the components of each cell is such that the metal interconnection pattern of a cell or a combination of cells for producing a given logic function may be inverted about the horizontal or the vertical plane of symmetry of the cell for producing a logic function relates to said given logic function.
