Graphite powder having a mean particle size not larger than 30 mu m is added to a negative electrode plate for a lead storage battery. Preferably, the amount of graphite powder added is in the range of from 0.3 % to 2 % by weight. Preferably, vein powder is used as the graphite powder. More preferably, 0.3 % or more by weight of an organic expander is added.

The apparatus has a multi-line detector system (6) in which individual columns of detector elements are displaced w.r.t. other columns. Arrays of detector elements may be combined in to detector modules, at least one of which is displaced w.r.t. an adjacent module in the rotation direction of a radiation source. The displacement may be equal to the length of a display element or a integer multipl...

The winder assembly, to form cylindrical cross wound bobbins (2), has a reciprocating yarn guide (3) with a guide eyelet (6) open at the top. An additional yarn guide (7,8) is at the reciprocating yarn guide (3), on both sides of the guide eyelet (6) and at a gap from it, extending over the movement plane (E2) of the guide (3). The deflector (9) of the winder assembly, is raised at set intervals ...

As necessary, material is converted to an adequately-high density for efficient pulverization. An Independent claim is included for plant executing the process. Ahead of the turbo-rotor (5), a batch- or continuous press or compression unit (2) consolidates the raw material. Preferred features: The continuous flow of low-density feedstock, is transformed before pulverization, into a flow of indivi...

The accumulator has an electrode (1) formed with a thin lead foil (2). On both sides layers of plastics material (3) are insulating and acid resistant. These layers carry layers of positive active lead oxide (4) and negative active lead (5). The plastics material layers are formed with circular apertures such that the lead oxide and lead paste contact the lead foil.The holes on the positive side h...
