摘要： A crankshaft for combustion engines has a number of components joined to each other. Each component comprises a counterweight, a portion of a main bearing journal, and a portion of a crank bearing journal. Adjacent components are so arranged that their crank bearing journal portions are connected to each other to form a complete crank bearing journal, and their main bearing journal portions are secured to each other to form a complete main bearing journal. One of each pair of portions is longer than the other; and oil ducts extend through cavities in the components but do not communicate with those cavities. Instead, the ends of the ducts open through the journal bearing surfaces, and specifically through the longer of the two journal portions so that the opening of the ducts can be central of the journal and still not interfere with the joint between the components.

摘要： An x-ray examination apparatus has a bent carrier having a first end to which a radiation source is attached and a second end to which an x-ray image intensifier is connected. The radiation source and the image intensifier are respectively connected to the carrier via individual, laterally projecting booms. Each boom is connected to the carrier so as to be rotatable around an axis at the end of the carrier to which it is connected. The arrangement allows unimpacted accessibility to the patient in different types of examinations.

摘要： In the case of a patient support apparatus, a support, rotatably mounted about a horizontal spatial axis, is height-, longitudinally- and laterally-adjustable relative to an x-ray apparatus, whereby at least the height adjustment proceeds by a motor. In order, in the case of a lengthwise displacement of the patient support, to automatically conduct such a height adjustment that the isocenter moves along a path--capable of being established in advance--along the support, it is provided in accordance with the disclosure that a processor constantly determines, for the actual coordinates of the spatial axis and of the tilt angle .alpha. of the support, the height of a desired examination point and compares it with the height of the isocenter. A follow-up control coupled with the processor ensures a constant adaptation of these two values.

摘要： A patient examination table, of the type used in an x-ray examination apparatus, has one end secured to a ceiling or floor stand via a tilt mechanism which permits the longitudinal axis of the table to be tilted upwardly or downwardly. The table can be tilted around an imaginary axis, the imaginary axis being movable roughly in the middle of the examination table. The tilt mechanism includes a driven element, which may be a part of the housing for the tilt mechanism, a first gear which is rigidly attached to the stand, a second gear which is rigidly attached to the examination table and a transmission linkage between the first and second gears which permits the second gear to be movable around the drive shaft of the first gear as the driven element is rotated. The second gear is rotated in an opposite direction to the direction of rotation of the driven element.

摘要： A method is described for producing castings and removing burrs produced during the casting at the parting line of the casting mold and in regions where cores are supported in core-supporting holes formed in the mold. The casting mold is so shaped that a well-defined burr, which includes a substantially uninterrupted flange projecting from the casting, is formed in the region of the casting which solidifies opposite the mold parting line. The mold may also be so shaped that a further well-defined burr, which includes a further substantially uninterrupted flange projecting from the casting, is formed in the region of the casting which solidifies where a core of the casting mold enters a core-supporting hole. After removal of the casting from the mold, the or each flange is removed by a mechanical cutting tool or by gas cutting, preferably by employing an industrial robot to effect relative movement between the flange and the flange-removing means.
摘要翻译：描述了一种用于生产铸件和去除在铸模分模线期间铸造期间产生的毛刺的方法以及在模具中形成的芯支撑孔中支撑芯体的区域。铸造模具的形状使得在铸件的区域中形成明确的毛刺，该毛刺包括从铸件突出的基本不间断的凸缘，其与模具分型线相对固化。模具也可以是这样的形状，使得在铸件的区域中形成另一个明确定义的毛刺，其中包括另外基本上不间断的凸缘突出的凸缘，其中铸模的芯进入芯支撑孔。在从模具移除铸件之后，通过机械切割工具或气体切割来移除或者每个凸缘，优选地通过使用工业机器人来实现凸缘和法兰移除装置之间的相对运动。
