    • There is described a new bending and squeezing blade for sheet metal bending machine. The blade comprises a bending tooth provided with a head surface that is suitable to engage the edge of a sheet metal to carry out its bending at 90° and with a foot surface that is suitable to engage the 90° folded edge of the sheet metal to carry out its additional bending at an angle greater than 90° and its possible squeezing on the remaining part of the sheet metal up to an angle substantially equal to 180°. In order to assure the locking of the sheet metal during the operation of squeezing the machine preferably comprises a blank holder provided with a pressing member, that can be controlled so as to project from the support foot of the blank holder in order to lock the sheet metal on a fixed counter blade.
    • 描述了一种用于钣金弯曲机的新型弯曲和挤压叶片。 刀片包括弯曲齿,其具有头表面,该头表面适于接合金属板的边缘以执行其在90°处的弯曲,并且具有适于接合金属板的90°折叠边缘的脚表面 以大于90°的角度执行附加的弯曲,并且可能在金属板的剩余部分上挤压到大致等于180°的角度。 为了确保在挤压操作期间金属板的锁定优选地包括设置有按压构件的坯料保持器,其可以被控制以从坯料保持器的支撑脚突出以便将片材 金属在固定的反向叶片上。

    • Apparatus and methods are disclosed for performing power compensation in a differential scanning calorimeter. The device operates by first subjecting only a reference material, in a single furnace, to a predetermined, variable, temperature program supplied by a program control. The values of the heating power supplied to the reference material are stored in a memory as a function of the temperature measured at the single furnace by a temperature sensor. The sample is then exposed, in the same furnace, to heating powers which are consecutively applied to the furnace, under program control, in accordance with the values stored in memory. The real temperatures of the sample are then measured by the temperature sensor. A supplementary compensating heating power is supplied to the sample, which power varies in accordance with the difference between the stored, programmed temperature and the real temperature in the sense of eliminating this temperature difference. This supplementary compensating heating power is then outputted to and registered, respectively, at an output device such as a recorded or computer.
    • 公开了用于在差示扫描量热计中进行功率补偿的装置和方法。 该装置通过首先在单个炉中仅使参考材料经受由程序控制提供的预定的,可变的温度程序。 提供给参考材料的加热功率的值根据温度传感器在单个炉中测量的温度存储在存储器中。 然后根据存储在存储器中的值,将样品在相同的炉中暴露于在程序控制下连续施加到炉的加热功率。 然后通过温度传感器测量样品的真实温度。 补充补偿加热功率被提供给样品,该功率在消除该温度差的意义上根据存储的,编程的温度和实际温度之间的差异而变化。 然后,这种补充补偿加热功率分别输出到输出设备,例如记录或计算机上并注册。
