The invention relates to an accumulator with two circuits, i.e. an accumulator having two circuits which contains a plurality of cells connected to one another in series, each individual cell within the cell having positive plates, connected to one another in parallel, and negative plates, connected to one another in parallel, which are arranged in a common acid chamber and are separated from one ...

Methods are disclosed for reproducibly fabricating and using <100> thermal-field built-up field emission cathodes through the selective thermal elimination of contaminants and preservation of specific surface oxides in conjunction with the application of an E-field to promote faceting of certain planes while discouraging faceting of the [100] planes. An example in which <100> oriented tungsten wir...

PURPOSE:In automatic change gear vehicles, to reduce the discharge of harmful component by preventing the quick increase of the negative pressure in a suction pipe when accelerator is reset after acceleration.

PURPOSE:Operation of clutches between engine and driving wheel is actuated by signals from fluid pressure and electronic control circuit.

An arrangement in association with infusion bags which are made of double layers of a soft, flexible film. Two separate chambers 10, 13 are formed between the films by means of joining the films in regions 3, 4, 6 around the chambers. The chambers are provided with connections 14, 17 through which infusion liquid can be withdrawn using a tubular member which has been passed through the connection....

A process for the production of combustible gas from waste materials and other combustible materials, in which the charge is dried, its combustible parts are subjected to low-temperature carbonization and the low-temperature carbonization gases are converted to combustible gas in a hot reaction bed. The charge is subjected to low-temperature carbonization at a temperature of from 300 DEG to 600 D...

A vibratory drive assembly for use with an electric motor driven apparatus comprising a plate driven in reciprocating vibratory movement and mounted on a frame via integral hinge strips which are arranged with their longitudinal directions transverse to the direction of vibratory movement and transverse to the longitudinal direction of an associated pin-shaped drive element.

Potassium is recovered as a dilute KOH solution from residue solids resulting from conversion of manganese ore to K2MnO4 by reacting the solids with a Ca(OH)2 under specified conditions. The resulting KOH solution can be returned to the K2MnO4 plant and the solids of reduced potassium content are suitable for disposal in a landfill.
