The lead accumulator has oxygen excess, and has auxiliary electrodes with less capacity than those normal. There is very little clearance between the two types of electrodes. Separators alongside the auxiliary electrodes are pref. of felted micro-glass wool, and have much lower resistance than those between the normal electrodes. - On charging oxygen commences to generate where the resistance is t...

There is described a device for producing heat energy and simultaneously auto-regulating the speed of a windmill or wind-turbine, which comprises a water brake or hydraulic brake mounted on the rotating shaft of a windmill or wind-turbine, which brake is comprised of a cylinder-shaped body (1), at least one rotor (16) mounted on said rotating shaft (2), and a stator (15) mounted about said rotatin...

The mechanism is for laying hoses or lines in the earth, and has a cutting blade (10) with a control (14) for hose insertion in the ground. This control comprises a telescopically projectable arm (3), one end of which is attached to a vehicle with a horizontally pivotable superstructure (2). - The other end of the arm has a holder (8) which supports the cutting blade, and which is rotatable around...

Packaging container for beer or other pressurized filled goods are conventionally manufactured in the form of metal cans. Attempts to use less expensive material, such as paper, has thus far been unsuccessful due to the material's lack of strength and difficulties in sealing gable tops and the jacket.This invention provides a packaging container and a method of manufacturing the same that eliminat...
