摘要： The autoclave cure process is the representative composite fabrication technique for high quality composite materials for the aerospace and defense industry application. After lay up and vacuum-bagging in a complicated sequence, the several composite material needed in autoclave curing are cured under controlled temperature and pressure. The autoclave curing, in which the total cure process requires at least 4-6 hours, is a very expensive process. Therefore, the determination of an optimal cure process for composite prepregs is very important for guaranteed quality as well as being important economically. Theoretical models cannot be proved because of the lack of experimental methods. The experimenter must run many batches of autoclave curing trial and error at the different curing temperatures and pressures to obtain a sufficient amount of data which can experimentally determine the optimal cure process. Because this invention can continuously monitor the change of thickness of the composite laminate during curing, this measuring system, which can determine the condition of an optimal cure process, is an excellent device to obtain the degree of curing and variation of thickness of a prepreg which is optimal in physical and mechanical properties.

摘要翻译： 高压釜固化工艺是用于航空航天和国防工业应用的高品质复合材料的代表性复合制造技术。 堆叠和真空袋装复杂后，高压釜固化所需的几种复合材料在受控的温度和压力下固化。 其中总固化过程需要至少4-6小时的高压釜固化是非常昂贵的过程。 因此，确定复合预浸料的最佳固化方法对于保证质量以及经济重要性非常重要。 由于缺乏实验方法，理论模型无法证明。 实验者必须在不同的固化温度和压力下运行许多批次的高压釜固化试验和误差，以获得足够数量的数据，这些数据可以通过实验来确定最佳固化过程。 由于本发明可以连续地监测固化期间复合层叠体的厚度变化，所以可以确定最佳固化过程的条件的该测量系统是获得固化程度和预浸料坯厚度变化的优良装置， 在物理和机械性能方面是最佳的。

摘要： A transmission assembly for a bicycle which is able to achieve variations in rotational force and velocity through internal gearing mechanisms which require no variation in sprocket diameter. The transmission assembly includes a front and rear transmission means, and a chain which connects them. Each transmission means includes one or more sprockets and gear sets with which the chain connects. Each gear set then includes a sun gear, a plurality of planetary pinions which rotate and revolve around the sun gear, a ring gear encasing the planetary pinions, and a carrier to which the planetary pinions are attached. This assembly helps prevent the chain from derailling, quickens the shifting process, and simplifies the structure and construction of transmission assemblies for bicycles.
