    • Apparatus for the formation of packages of elongated flexible material wound upon a pirn supported and rotated in the apparatus, the apparatus having an operating carriage mounted for reciprocation parallel to the axis of the pirn, mechanism for reciprocating the operating carriage with a basic reciprocating movement lengthwise of the pirn, a vibrator mounted upon the operating carriage, a thread guide vibrated by the vibrator in a direction lengthwise of the pirn with an amplitude which is a fraction of the amplitude of reciprocation of the operating carriage, and a controlling mechanism for insuring the periodic translational shifting of the thread guide to the top of the pirn. The operating carriage is mounted upon guideways fixed to the body of the apparatus and extending parallel to the axis of the pirn, a driving belt for the carriage having spaced parallel runs thereof extending parallel to the carriage, the carriage being selectively clamped to one or the other of the rectilinear runs of the driving belt so as to drive the carriage in the direction of the run of the belt thus gripped. The controlling mechanism comprises a controlling belt stretched between rollers at the opposite ends of the body of the apparatus, the controlling belt bearing switching dogs for controlling the mechanism which selectively clamps the carriage to one or the other of the rectilinear runs of the driving belt.
    • 用于形成缠绕在设备中支撑和旋转的皮条上的细长柔性材料的包装的装置,该装置具有安装成平行于皮条的轴线往复运动的操作托架,用于使操作托架以基本的往复运动纵向往复运动的机构 安装在操作台架上的振动器,由振动器沿斜边纵向方向振动的螺纹导向器,幅度为操作台车的往复运动幅度的一小部分;以及控制机构, 将导纱器周期性地平移到皮条的顶部。 操作托架安装在固定到设备主体并平行于皮条的轴线延伸的导轨上,用于托架的驱动带具有平行于托架的间隔开的平行延伸,托架被选择性地夹紧到一个或 驱动带的其他直线运行,从而沿着如此抓握的带的运行方向驱动托架。 该控制机构包括一个控制带,该控制带在装置主体的相对端处的辊之间拉伸,控制带承载切换杆用于控制将滑架选择性地夹紧到驱动带的直线运动中的一个或另一个的机构。

    • An elastically deformable plastic cap for containers such as bottles having necks, such containers containing materials under pressure, such as aerated liquids. The cap consists of two cylinders disposed concentrically one within the other. The outer cylinder has a sealing ring with a sealing edge at its lower end and the inner cylinder is closed at its bottom end with a diaphragm. The cylinders are connected at their upper ends by means of a ring. The bottom surface of the diaphragm and the bottom surface of the sealing ring are disposed in a first common plane; the sealing edges on the inner surface of the sealing ring and the outer surface of the inner cylinder respectively and the upper surface of the diaphragm lying in a second common plane, the second plane being parallel and above the first common plane. Preferably the inner side wall of the inner cylinder is provided with an annular step, and the inner part of the inner cylinder above the diaphragm and the outer part of the inner cylinder in the plane of the diaphragm are bevelled in the same direction to provide an outwardly and upwardly expanding frusto-conical portion connecting the lower end of the inner cylinder with the outer edge of the diaphragm.
    • 用于诸如具有颈部的瓶的容器的可弹性变形的塑料盖,这种容器包含在压力下的材料,例如充气液体。 盖子由两个圆筒组成,同心地放置在另一个中。 外筒具有在其下端具有密封边缘的密封环,并且内筒在其底端处用隔膜封闭。 气缸在其上端通过环连接。 膜片的底面和密封环的底面设置在第一公共平面内; 所述密封环的内表面和所述内筒的外表面上的密封边缘和所述隔膜的上表面位于第二公共平面中,所述第二平面平行并位于所述第一公共平面之上。 优选地,内筒的内侧壁设置有环状台阶,并且在隔膜的上方的内筒的内部部分和隔膜的平面内的内筒的外部部分在同一方向上被倾斜以提供 向外和向上扩展连接内筒的下端与隔膜的外边缘的截头圆锥形部分。
