摘要： A molded, one-piece plastic dental treatment tray for applying fluoride or other medication to a patient's teeth. The tray has a pair of elongated locking flanges on one of its handles which engage the lateral edges of the other of its handles to hold the tray folded up with its two teeth receiving troughs in an aligned, assembled relationship. At least one of the handles is molded at an angle with respect to the bottom of its trough to help ensure that when the tray is folded up, the free ends of its troughs are urged into contact with each other, to enable the tray to be inserted more easily into the patient's mouth. The bottoms of the troughs are flat and smooth enough for them to move easily over each other in any direction while in the patient's mouth, so the tray will better accommodate any individual differences in the mouth, jaws or teeth of the particular patient.
摘要翻译：一种用于向患者牙齿施加氟化物或其他药物的模制的单件塑料牙科治疗托盘。托盘在其一个手柄上具有一对细长的锁定凸缘，其接合另一个手柄的侧边缘，以将托盘折叠成两个接受槽的对齐的组装关系。手柄中的至少一个相对于其槽的底部以一定角度模制，以帮助确保当托盘折叠时，其槽的自由端被推动彼此接触，以使托盘能够更容易插入患者口中。槽的底部是平坦和光滑的，使得它们能够在患者口中以任何方向容易地彼此移动，因此托盘将更好地适应特定患者的嘴，颌或牙齿中的任何个体差异。

摘要： A mechanism for producing a multiple number of drum beats from a single downward depression of a drum foot pedal. A slipping linkage is utilized to produce multiple oscillations of a shaft member during the continuous downward motion of the drum pedal. The drum mallet is attached to the oscillatory shaft and therefore produces a number of beats for each foot pedal depression.

摘要： Disclosed herein are methods for controlling bubble formation in a polymerization reactor. The method includes: (a) determining a concentration of at least one component at a location in the reactor using a mathematical model; (b) determining a vapor pressure of the composition based at least in part upon the concentration of the component; (c) determining an operating pressure of the reactor at the location; (d) determining a pressure difference as ΔP=PX−PV, wherein PX is the operating pressure and PV is the vapor pressure; (e) comparing the ΔP to a threshold value; and (f) implementing an effect when the ΔP is less than the threshold value.
