Abstract: The invention relates to performance improvements in lead accumulators and lead-acid batteries by admixing so-called expanders or spreading materials to the active negative materials. Succinates are proposed as a new synthetic and consequently chemically clearly defined spreading means that can be used in place of lignin sulphonates, particularly iminodisuccinates or succinyl groups or oligomers containing iminosuccinyl groups or polymer compounds, individually or in any mixtures.

Abstract: An apparatus and method of varying the tonal aspects of a string instrument such as an acoustic or electric guitar which is commonly provided with a body and a fret board on the instrument's neck. The apparatus includes an upper portion and a lower portion. The lower portion is configured to connect with the fret board and to provide a base for the upper portion, The upper portion is configured to engage the lower portion. The upper portion is also configured to receive and support an instrument's strings. The upper portion is selectively movable relative to the lower portion by an operator to change the tonal nature of the instrument.

Abstract: The invention relates to a method for converting a separator processing machine for processing separators for a lead accumulator, comprising the steps of ending a supply of a first separator having a first separator width to the separator processing machine and supplying a second separator having a second separator width that differs from the first separator width to the separator processing machine. According to the invention, the separators comprise a base film body extending along a center line and a plurality of primary ribs, which are raised above the base film body along the center line by a primary rib height and are disposed mirror-symmetrically with respect to the center line, wherein the primary ribs of the second separator with respect to the center line are disposed in the same locations as the primary ribs of the first separator.

Abstract: The invention relates to a laminar textile material for covering a pasty active mass on a battery electrode. The invention further relates to a battery electrode having such a material, to a battery, and to a method for producing battery electrodes. Potential improvements of lead batteries are disclosed that are more practical than previously known solutions, and that stabilize the pasty active mass on the battery electrodes. A laminar textile materiel is disclosed to this end, comprising glass fibers and fibers made of a thermoplastic plastic, e.g. polyester.
