An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related ...

Apparatus for inspecting the sealing surface area (36) of a container finish (34) that includes a structured light source (44) positioned to direct a collimated line-shaped light beam (46) onto the sealing surface area of a container as the container is moved relative to the light source. The line-shaped light beam at the container sealing surface area has a long dimension orthogonal to the contai...

The object of the invention consists in a compacting process in powder metallurgy for preparing powders to sintering operations, in which process the powders, after mixing the same with solid lubricants and liquid solvents, are preheated up to a temperature between the room temperature and the softening temperature of the lubricant employed.

A laminated film consists of a laminated membrane having as main component a wax compsn on at least one of the surfaces of a polyester film. The laminated film is characterised in that it has at least 20 pcs/100 microm 2 of protuberances having a longitudinal length/transverse length ratio of at least 3 on its surface.

A heat-insulating constructional material based on an alkalized and flooded siliceous raw material fabricated by comminuting solid ingredients and mixing all the raw ingredients, steaming a raw mixture and thermally bloating intermediate products obtained from the steamed raw mixture is designed for utilisation as warmth-keeping fills and light-weight concrete aggregates (in a particulate form) an...

A composite is produced by arranging several different materials, one of which is a material with oriented reinforcement, pre-impregnated with a resin and moulding at raised temp. for a time sufficient to harden the resin and ensure bonding between the components. The components, including the resin, are arranged at the same time, before raising the temp., i.e. the resin is not injected separately...

The present invention is to prevent stagnation, adhesion, or growth of a powdery polymer below a gas dispersing plate of a gaseous phase polymerizer, and therefore can prevent thr choking of the gas dispersing plate with the powdery polymer. An inclined member is provided below the gas dispersing plate of the polymerizer for distributing the flow of the gaseous phase toward the gas dispersing plat...
