The invention relates to a machine for compacting and/or crushing bulk goods, two rollers (1) which can be pressed against one another at high pressure consisting in each case of a roller base body (3) and a roller case which is detachably connected to the roller base body and composed of individual segments (4). The individual segments (4) contain on the front longitudinal side in the direction o...

An electric double layer capacitor employs a paste electrode (33) between collector electrodes (34). The paste electrode (33) is compressed under a small load because the collector electrodes (34) are pressed by compression plates (21) in only an area corresponding to the paste electrode (33). With the paste electrode (33) thus compressed, the internal resistance of the capacitor is reduced and th...

The polarising electrode of an electrical double-layer capacitor cell is constituted with solid plate-like polarising electrodes (61,71) and paste-like polarising electrodes (6,7). The solid plate-like polarising electrodes (61,71) are counterposedly arranged by being separated with a separator (5). The paste-like polarising electrodes (6,7) are coated on the surfaces at the outside of the solid p...

In producing an electrical double-layer capacitor cell, when the polarising electrode ( 61,71 ) is formed by sintering to the collecting electrode ( 11,21 ) obtained by sintering a conductive powder into plate-like form, the contact resistance between the collecting electrode ( 11,21 ) and the polarising electrode ( 61,71 ) becomes extremely small. Thereby, the internal resistance of the electrica...

A battery charger having positioning and support apparatus for aligning batteries of varying sizes is disclosed. A recess in the battery charger housing has tapering sides which produce a charging pocket wider toward the front of the charger than toward the rear. Batteries of varying thickness have sloping sides which conform to the angle of taper of the battery charger. Rib members on the taperin...
