Abstract: A separator (1) for electrode plates (2) in gel storage batteries having two substantially rectangular layers (3, 3?) of a flat separator material, which layers come to lie in mutually superposed relationship. In order to provide less expensive separators for the separation of plate electrodes in gel storage batteries, which have a low electrical resistance and which afford additional protection for the edges and side surfaces and at the same time permit homogenous gel filling of the storage battery, the invention proposes that the two layers of separator material are connected together at least portion-wise in the region of their edges, forming a casing or pocket for the introduction of an electrode plate and a method and battery employing the separator.

Abstract: The invention relates to a cell connector (6) for a battery, especially for absorbing, in conjunction with at least one damping element (9), the vertical forces that are caused by the impact of shocks. The cell connector (6), at one end, is connected to the positive or negative electrodes (4, 5) which are received in a housing (2) having a housing cover (3), and, at the other end, comprises at least one terminal (7, 8) projecting from the housing cover (3). The aim of the invention is to elastically dampen the electrode plates (4, 5) of an accumulator (1) which are disposed inside a housing (2). For this purpose, a terminal (6) having a supporting shoulder (11), integrally molded thereto, is used in the housing (2), a damping element (9), disposed between the housing cover (3) of an accumulator (1) and the cell connector (6), coming to rest thereon.

Abstract: A method of synthetic imaging comprising the steps of: emitting a first electromagnetic signal having a first frequency from a first radiation source, emitting at least one second electromagnetic signal having a second frequency from a second radiation source, wherein the first and second frequencies are different from each other, substantially simultaneously receiving the first signal and the second signal with a first receiver, substantially simultaneously receiving the first signal and the second signal with at least one second receiver, arranging an object on the path of at least one electromagnetic signal between the radiation sources and the receivers, wherein the signals are reflected by the object before they meet the receivers, and computing an image of the object from the signals received by the receivers and a device for practicing the method.
