摘要： Disclosed is a traversing microtome having a base (10) and a movable carriage (13). A blade holder (12) with a blade (16) is mounted on the base (10), and an object holder (14) is mounted on the carriage (13). To carry out the cutting process, the carriage (13), together with the object holder (14) and the object (15), is moved against the stationary blade (16). Between the guide rails (18,18') of the base (10) and the carriage (13) a bearing gap (30) with a width of a few microns is created by means of air bearing elements (21,21'), and consequently only a minimal force is required to move the slide (13). Between the air bearing elements (21,21'), magnets (22,22') are arranged so that their attracting forces act against the air pressure of the air bearing elements. In this manner, the force needed to arrest the motion of the carriage (13) at any given location of the guide rails (18,18') is extremely low. The carriage (13) cannot be moved when the supply of air is interrupted. The air bearing elements are suspended in the manner of a pendulum and are adjustable in height; the latter is true for the magnets (22,22') also. In view of the air bearings, no lubrication is required for the guide rails (18,18').

摘要： A microtome actuable both manually and by a motor, with a single coupling element, whereby rotation of the hand wheel when the motor drive is engaged and thus the risk of injury by the manual grip are excluded. The coupling element is located in the hand wheel and is capable of locking in two positions by means of pulling and rotating, the respective positions establishing the manual or motor drive mode. The drive mode is made readily apparent from the outside by means of symbols. In the hand wheel, an equalizing weight for the object carriage is provided.
摘要翻译：切片机可手动地和通过电动机致动，具有单个联接元件，由此在电动机驱动器接合时手轮的旋转被排除在外，并且因此手动把手的伤害风险被排除在外。耦合元件位于手轮中，并且能够通过拉动和旋转锁定在两个位置，各个位置建立手动或电动机驱动模式。驱动模式通过符号从外部显而易见。在手轮中，提供了用于对象托架的均衡重量。

摘要： A method for determining the element concentration in electron beam melting is used for the continous measurement during the melting process especially for melting alloys. According to the invention, the X-radiation generated during melting is utilized by concurrently measuring the intensity of the characteristic radiation of the element to be determined and the intensity of another portion of the X-ray spectrum from the same location of the melt. The quotient of both measurands then is a function of the concentration of the element to be determined.
