    • In an electrical lamp, whose envelope is closed by a pinch of rectangular cross-section, through which current-supply conductors are passed and which is supported in a cap between inwardly projecting parts, which seize around the narrower side faces of the pinch, according to the invention, one of the current supply conductors is bent backwards with its part projecting from the pinch along one of the narrower side faces and is clamped between pinch and lamp cap. Thus, it is possible to use a cap having only one bottom contact and nevertheless to secure the lamp envelope to the cap without additional means.
    • 在电灯中,其外壳由矩形横截面封闭,供电导体通过该电灯,并被夹持在向内突出部分之间的盖中,这两个部分围绕夹点的较窄侧面捕获, 对于本发明,电流供应导体中的一个向后弯曲,其部分从夹紧部分沿着较窄侧面中的一个突出,并且夹在夹头和灯头之间。 因此,可以使用仅具有一个底部接触件的盖,并且仍然可以将灯泡固定到盖上而无需附加的装置。

    • In a feed pump (2) designed as a peripheral or side channel pump, guide vanes (9, 11, 12) arranged in an impeller (4) have a different angle of inclination in the radially inner region from the radially outer region. As a result, the characteristic curve of the feed pump (2) can be modified simply by exchanging the impeller (4). By virtue of the invention, the feed pump (2), whilst having an intended feed pressure and volume flow, can be set to particularly high efficiency, depending on the viscosity of the liquid to be fed.
    • 在设计为周边或侧面通道泵的供给泵(2)中,布置在叶轮(4)中的导向叶片(9,11,12)在径向外部区域的径向内部区域中具有不同的倾斜角。 因此,可以简单地通过更换叶轮(4)来改变进给泵(2)的特性曲线。 根据本发明,进料泵(2)虽然具有预期的进料压力和体积流量,但可以根据待进料液体的粘度而特别高的设定。
