A system and method for filling pot holes. The system includes transferring aggregate from an aggregate tank. Activator is likewise transferred from an activator tank. The activator is mixed with the aggregate to form a homogenized mixture. A liquid is introduced into a homogenized mixture to form a slurry and then a pot hole filler. The pot hole filler is directed through an exit end of a mixing tube.

A memory element of the present invention is split to minimize the magnitude of electrical current flowing therethrough as the split memory element is being heated to its transitional temperature, thereby permitting the cross-sectional area of the lead wires used to conduct an electric current to the memory element to be minimized. The split memory element includes a tip member and first and second strip members aligned in side-by-side relation. Each of the tip member, first strip member, and second strip member are made of a shape-memory alloy and have a characteristic internal structure. Each strip member includes a shape-memory portion coupled to the tip member, a lead-attachment portion, and partition means for interconnecting the shape-memory and lead-attachment portions. Each partition means has an internal structure which is dissimilar to the characteristic internal structure of the tip member and the first and second strip members so that certain ions originating in the electrically conductive wire lead coupled to the lead-attachment portions are substantially isolated or otherwise contained in the lead-attachment portions to prevent contamination of the shape-memory portions.

Carbon nanotubes are grown directly on metal substrates using chemical vapor deposition. Metal substrates are comprised of catalysts which facilitate or promote the growth of carbon nanotubes. The nanotube coated metal substrates have applications including, but not limited to, heat transfer and thermal control, hydrogen storage, fuel cell catalytic reformers, electronics and semiconductors, implantable medical devices or prostheses, and tribological wear and protective coatings.

A compact and lightweight electric generator for portable power applications employs a new engine design and integration approach for reducing engine and generator weight. A unique flywheel alternator generates electrical power and provides inertia for the engine, pressurized air for cooling, and inertia for the alternator. An engine cowling provides rotating component protection, a fan shroud mechanism, cooling air ducts, and a cooling mechanism for handling large quantities of heat produced by rectified power conversion.
摘要:
A system and method for applying a coating to a surface. The coating can include any typical coating, but in some examples includes a styrenated acrylic coating. The coating is first applied. Thereafter, a quick-set formula which includes a brine solution is applied atop the first coating. The quick-set formula sets the first coating. Thereafter, a second coating, or multiple coatings, can be applied atop the first coating. Due to the quick-set formula, the second coating can be applied in less than 15 minutes.

A compact and lightweight electric generator for portable power applications employs a new engine design and integration approach for reducing engine, generator, and starter weight. A unique flywheel alternator/starter configuration that generates electrical power, rotates the engine for starting, provides inertia for smooth engine operation, pressurized air for cooling, and inertia for the alternator. An engine cowling provides rotating component protection, a fan shroud mechanism, cooling air ducts, and a cooling mechanism for handling large quantities of heat produced by rectified power conversion. An electrical hook up that allows the generator to provide transient surge capacity for starting inductive loads, or improved load leveling and fuel efficiency.
