Abstract: A battery bushing for rechargeable batteries has mounting and contacting sections and a torque ring between these sections. The torque ring or the outer surface can be endowed with several indentations. The mounting section is configured to hold the battery bushing within a battery cover, into which it is preferably injection molded. The battery bushing is a hollow body with outer and inner walls. At the contacting section, the outer wall is conically shaped. At the mounting section, the outer wall has at least one circumferential projection forming a labyrinth. The inner wall comprises at least an upper section, approximately surrounded by the contacting section and preferably having a conical shape, and a lower section approximately surrounded by the mounting section. The lower section preferably has (in a lateral sectional view) a concave shape. Between the upper and lower sections, there may be an edge or a step.

Abstract: A battery bushing for a rechargeable battery has a mounting section and a contacting section. There is a torque ring, between the mounting section and the contacting section. The torque ring or the outer surface itself can be endowed with several indentations. The mounting section is configured to hold the battery bushing within a battery cover, into which it preferably is injection molded. The battery bushing is a hollow body, which has an outer wall and an inner wall. At the contacting section, the outer wall is conically shaped. At the mounting section, the outer wall has at least one circumferential projection forming a labyrinth. The inner wall comprises at least two sections. An upper section is approximately surrounded by the contacting section, and preferably has a conical shape. A lower section is approximately surrounded by the mounting section. The lower section preferably has (in a lateral sectional view) a concave shape.

Abstract: A terminal for a battery has a mounting section and a contacting section. There is a torque ring between the mounting section and the contacting section. The mounting section is for holding the terminal within a battery cover, into which it preferably is injection molded. The terminal is a hollow body, which has an outer surface and an inner surface. At the contacting section, the outer surface is conically shaped. At the mounting section, the outer surface has at least one labyrinth ring forming a labyrinth. The inner surface comprises at least two sections. An upper section is essentially surrounded by the contacting section, and preferably has a conical shape. A lower section is essentially surrounded by the mounting section. The lower section preferably has a concave cross-sectional shape. Between the upper section and the lower section, there is an edge. The edge at the inner surface may be essentially surrounded by the torque ring at the outer surface.

Abstract: The invention relates to a copper-tin alloy, comprising 0.2 to 0.8% by weight Sn, 0.1 to 0.6% by weight Ni and/or Co, 0 to 0.05% by weight Zn, 0 to 0.2% by weight Fe, 0.008 to 0.05% by weight P, and also Cu as remainder. The invention furthermore relates to a corresponding composite material having a base material made of such an alloy and also to suitable uses thereof. The technological and physical properties are comparable with those of a CuFe2P alloy. However, the alloy according to the invention and also a tin-plated composite material made thereof can be readily recycled.

Abstract: According to the invention, a time emitter of a subscriber (1) provided as a reference in a network regularly and/or randomly transmits reference time signals (TR1). A subscriber (2) approximately adjusts the local time measurement thereof in relation to the time measurement of the reference subscriber (1) only if the difference between the reference time (TR) and local time (TL) is less than a predetermined or predeterminable threshold value (e), at the moment when the reference time signal is received and/or a signal path is kept clear between the subscriber (2) and the reference subscriber (1) or the network for instantaneous data transmission.
