Copper-catalyzed formation of carbon-heteroatom and carbon-carbon bonds

The present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide or amine moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In additional embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between a nitrogen atom of an acyl hydrazine and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of a nitrogen-containing heteroaromatic, e.g., indole, pyrazole, and indazole, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-oxygen bond between the oxygen atom of an alcohol and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. The present invention also relates to copper-catalyzed methods of forming a carbon-carbon bond between a reactant comprising a nucleophilic carbon atom, e.g., an enolate or malonate anion, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. Importantly, all the methods of the present invention are relatively inexpensive to practice due to the low cost of the copper comprised by the catalysts.

Velocity, internal ballistics and external ballistics detection and control for projectile devices and a reduction in device related pollution

Improvements to projectile devices (particularly air guns) include techniques for measuring and controlling the velocity of projectiles in the barrel and after leaving the barrel, allowing the use of non-toxic projectiles. Tracking of a projectile's flight by its unique sound and / or its unique electromagnetic signal or signal modulation are also provided, along with after-barrel guidance that can be used to improve accuracy. Control for discriminating between authorized and unauthorized users is also provided. A projectile device can also be used for inexpensive and harmless practice using optical and / or acoustic information gathered by targeting and imaging systems built into the device.

Smps circuit with multiple ac/dc inputs and application of such circuit to computer power supplies or laptop adapters

The invention relates to a switch mode power supply (SMPS—Switching Mode Power Supply) which provides the output voltages generated in the AC-network-input switch mode power supply (SMPS—Switching Mode Power Supply) circuits also with battery and similar supply inputs when necessary by using a shared power transformer (T3) having separate power input windings (7, 6) appropriate for the particular input voltage for each input supply and the power switching transistors (Q1, Q2, Q5, Q6) connected to this windings in accordance with the topology used and, which other remaining control, feedback, output rectifying and filtering circuits and other windings of the transformer are single and shared without using a second independent power supply or regulator circuit in addition to the network-input power supply. By the addition of a small dry battery, this concept is applied to the computer power supplies in order to develop an economical Uninterruptible Computer Power Supply (UCPS), which could be installed to the power supply housing in the computer case and which could power the monitor as well. It has also been applied to the laptop computer adaptors and a two-supply-input laptop computer adaptor, which works either from the automobile lighter outlet or from the network with a single adaptor, has been developed.

Municipal Casting Frame and Method of Manufacturing Same

ActiveUS20070237580A1Easily retrofittedInexpensive and practicalArtificial islandsFoundry moulding apparatusStructural engineeringManufacturing engineering
A municipal casting frame is provided with cast nut retainers that allow the frame to be used with or without a bolt-down cover. The frame defines one or more bolt holes of sufficient dimension to allow free passage of the cover bolts. The undersurface of the frame defines a cast nut retainer adapted to securely receive a nut. In one embodiment, the nut retainer includes protrusions that permit the nut to be snap-fitted into the nut retainer. In another embodiment, the nut retainer is configured to frictionally receive the nut in a wedging interaction. The present invention also provides a method for manufacturing a frame with integral cast nut retainers. The method generally includes the steps of (a) providing a core corresponding in shape to the bolt hole and the cast nut retainer, the cast nut retainer being configured to receive and retain a nut, (b) casting a frame in a mold about the core, (c) removing the cast frame from the mold and (d) removing the core from the cast frame. The process may also include the step of inserting a nut into the cast nut retainer in a direction that is in substantial coaxial alignment with the bolt hole.
