摘要： A mixing valve apparatus is disclosed, for producing a mixed fluid of a desired temperature obtained by mixing high temperature fluid and low temperature fluid with each other. The apparatus includes a pressure-sensitive control unit (6) which operates in response to the differential pressure (.DELTA.P) between the inlet pressure of the low temperature fluid and the pressure of the mixed fluid, and which unit controls the opening degree of an inlet valve (V.sub.1) for the high temperature fluid. Pilot passage (R.sub.0 .about.R.sub.3) for communicating the inlet pressure of the low temperature fluid to said unit is provided with a throttle (L, L.sub.1) whose effective surface area varies in response to the temperature of the mixed fluid, to compensate the opening degree of the inlet valve (V.sub.1) for the high temperature fluid upon variation of the temperature of the mixed fluid.

摘要： A method of and an apparatus for making a dental set-up model utilizable in the practice of orthodontics and, more particularly, to facilitation of making the dental set-up model. The shape of an impression which is a replica of dental teeth and dental alveolar ridges of a patient is first converted on a non-contact basis into electronic data by means of a three-dimensional profile analyzer utilizing an irradiation beam. Using this electronic data and within the framework of such electronic data, representative plane defined by anatomically proximal contact points A1, anatomically distal contact points A2 and an intermediate point E between the bucco-cervical point B1 and the lingo-cervical point B2 are formed by cutting out the individual teeth. Subsequently, for each tooth, a DI line, which is a straight line connecting between the bucco-cervical point B1 and a representative point C of a cusp or edge that has been projected onto the representative plane, and a DH line intersecting the DI line perpendicularly at a point spaced a predetermined distance from the representative point C towards the dental alveolar ridge are formed. Then, the DH lines for the respective teeth are arranged on a plane along a guide line descriptive of an ideal individual dental arch form and respective heights of the DH lines for all teeth which have been lined up to a predetermined height are adjusted to a predetermined level, followed by adjustment of the angle of inclination of the representative plane for each tooth relative to a facial reference line set up on the face.
摘要翻译： 一种用于制造牙科设置模型的方法和装置，其可用于实践口腔正畸学，并且更具体地涉及促进制作牙科装置模型。 首先，通过利用照射光束的三维轮廓分析仪，首先将患者的牙齿和牙槽嵴的复制品的形状在非接触的基础上转换为电子数据。 使用该电子数据并且在这样的电子数据的框架内，通过解剖学上近端的接触点A1，解剖学远端接触点A2和颊部颈部点B1和侧颈部点B2之间的中间点E限定的代表性平面由 切出个别的牙齿。 随后，对于每个牙齿，DI线是连接颊部颈部点B1和已经投影到代表性平面上的尖点或边缘的代表点C之间的直线以及与DI线相交的DH线 形成了与代表点C间隔开预定距离朝向牙槽嵴的点垂直的位置。 然后，各齿的DH线沿着描述理想的单独牙弓形状的引导线布置在平面上，并且已经排列到预定高度的所有齿的DH线的相应高度被调节到预定的 水平，然后调整每个牙齿的代表性平面相对于设在脸部上的面部参考线的倾斜角度。

摘要： A bimetal steam trap is disclosed, which includes a temperature-responsive valve arrangement and a bimetallic column formed of a plurality of pairs of bimetallic discs which are superposed with each other. The valve arrangement has a valve element normally biased by a spring toward its open position, which biasing force is overcome by the thermal expansion axial thrust generated by the bimetallic column when condensation temperature within the steam trap is above a predetermined level. To permit an axial displacement of the valve element in precise alignment with associated valve opening, an elongate valve member is provided at one end with the valve element, and serves to support the bimetallic column as an integrated sub-assembly.
