    • An operating table comprises a patient rest or support structure which is mounted at a rolling bearing, i.e. a bearing associated with the rolling motion of the patient rest or support structure. The axis of this rolling bearing corresponds with a rolling or roll axis and defines a predetermined angle with the patient rest or support structure, so that the extension of the axis of the rolling bearing, subsequent to intersection thereof with the plane of the patient rest or support structure at a predetermined punctiform location, extends substantially through the center of an operating site defined in or at the head of a patient stretched out on the patient rest or support structure. In this manner, it is rendered possible that, when rolling movements or motions with the patient rest or support structure are accomplished by means of a suitable drive for such rolling motion, the center of the operating site remains essentially unchanged at the same location. By virture of this arrangement of the rolling or roll axis, the expenditure for adjusting means and mechanisms for the rolling or pivotal movement of the patient rest or support structure is considerably reduced.
    • 操作台包括安装在滚动轴承,即与患者休息或支撑结构的滚动运动相关的轴承的患者休息或支撑结构。 该滚动轴承的轴线对应于滚动或滚动轴线,并且与患者休息或支撑结构形成预定的角度,从而在与患者休息或平面相交之后滚动轴承的轴线延伸 在预定的点状位置处的支撑结构基本上延伸穿过在患者休息或支撑结构上伸展的患者的头部中或位于头部的操作部位的中心。 以这种方式,当使用患者休息或支撑结构的滚动运动或运动通过用于这种滚动运动的合适的驱动来实现时,可能的是,操作部位的中心在相同的位置保持基本不变。 通过滚动或滚动轴线的这种布置,病人休息或支撑结构的滚动或枢转运动的调节装置和机构的费用大大降低。

    • In a gasification burner comprising an antechamber for mixing fuel and primary air; a catalytic device for generating a fuel gas from the fuel/primary air mixture; a mixing chamber for mixing the fuel gas with secondary air; an annular space which surrounds the antechamber, the catalytic device and the mixing chamber being separated from the antechamber by a ring wall provided with radial canals; a combustion chamber and a burner plate terminating the combustion chamber; and an ignition chamber arranged between the combustion chamber and the mixing chamber the operating safety is increased by having the annular space also enclose the ignition chamber and the combustion chamber in ring-fashion and extend up to the vicinity of the burner plate; a primary air feed stub opening into the annular space; and baffles in the annular space which baffles conduct the primary air stream from the primary air feed stub to the radial canals of the ring wall in spiral or meander fashion about the combustion chamber and the ignition chamber.
    • 一种气化燃烧器,包括用于混合燃料和一次空气的前室; 用于从燃料/一次空气混合物产生燃料气体的催化装置; 用于将燃料气体与二次空气混合的混合室; 围绕前室的环形空间,催化装置和混合室通过设置有径向运河的环壁与前室隔开; 燃烧室和终止燃烧室的燃烧器板; 以及设置在所述燃烧室和所述混合室之间的点火室,通过使所述环形空间也环绕所述点火室和所述燃烧室并且延伸到所述燃烧器板附近而增加所述操作安全性; 进入环形空间的一次空气进料支管; 以及环形空间中的挡板,该挡板将一次气流从一次空气进料柱传导到围绕燃烧室和点燃室的螺旋或曲折形式的环壁的径向通道。
