    • An apparatus for solder joining metal tapes to form laminated metal tapes comprises an alignment box having a base and a sidewall means extending therefrom to define a tapered inner channel extending through the box. The tapered channel having an entrance end and narrowing to an exit end. At least one tapered wall extending from the base and within the inner channel to define subchannels that are spaced at the entrance end and converge into the inner channel before the exit end. The sidewall means and tapered wall extending from the base to respective wall tops, and a cover extending over the channel and subchannels is mounted on the wall tops. The base, sidewalls, inner wall, and cover being configured to form the channel and subchannels to have a first preselected distance between the base and cover that is greater than the width of the tapes. A second preselected distance between oppositely facing walls bordering the subchannels that is greater than the thickness of the tapes, and a third preselected distance between oppositely facing walls at the exit end that is greater than the thickness of the laminated tapes. A solder duct means mounted on the box for directing molten solder into the inner channel to flow from the exit end to the entrance end. The solder duct means having a slot extending therethrough and aligned with the exit end. A seal means mounted on the solder duct means adjacent the slot for minimizing solder escaping from the slot while solder coated tapes pass therefrom, and a wiper means mounted on the solder duct means and positioned from the seal means removes excess solder from tapes passing through the seal means.
    • 用于焊接金属带以形成层压金属带的装置包括具有基座和从其延伸的侧壁装置的对准盒,以限定延伸穿过箱体的锥形内部通道。 锥形通道具有入口端并变窄到出口端。 至少一个锥形壁,其从底部延伸并且在内部通道内,以限定在入口端处间隔开并在出口端之前会聚到内部通道中的子通道。 侧壁装置和锥形壁从基座延伸到相应的壁顶,并且在通道和子通道上延伸的盖安装在壁顶上。 基座,侧壁,内壁和盖被构造成形成通道和子通道,以使得基座和盖之间的第一预选距离大于带的宽度。 邻近子通道的相对面对的墙壁之间的第二个预选距离大于带子的厚度,以及在出口端处相对面对的壁之间的第三个预选距离大于层压带的厚度。 安装在盒子上的焊接管道装置,用于将熔融焊料引导到内部通道中以从出口端流到入口端。 焊料管道装置具有延伸穿过其并与出口端对齐的槽。 密封装置安装在邻近槽的焊料管道装置上,用于使焊料从槽中逸出而最小化,同时焊接涂覆的带从其中通过,并且安装在焊料管道装置上并从密封装置定位的擦拭装置从穿过 密封方式。

    • In a rolling loop motion picture apparatus, such as a projector or camera, the movie film is pressed against a film supporting surface disposed within a light path. In order to be cleaned, the film supporting surface is moved out of the light path to an inoperative position opposite a sheet of material formed of an inert polyurethane material to which particulate contaminants adhere. The sheet is moved into contact with the film supporting surface, whereby the particulate contaminants adhere to the sheet. Then the sheet is retracted from the film supporting surface, along with the particulate contaminants. The film is guided between fixed and movable guide surfaces. The movable guide surface is spring-biased downwardly against the top edge of the film and is constrained against horizontal movement.
    • 在诸如投影仪或相机的滚动循环电影设备中,电影胶片被压靠在设置在光路内的胶片支撑表面。 为了清洁,薄膜支撑表面从光路移出到与由颗粒污染物粘附的惰性聚氨酯材料形成的材料片相对的不工作位置。 片材移动与膜支撑表面接触,由此颗粒污染物粘附到片材上。 然后片材与颗粒污染物一起从膜支撑表面缩回。 胶片在固定和可移动的导向表面之间引导。 可移动的导向表面被弹性偏压抵靠胶片的顶部边缘并被限制在水平运动上。

    • The method and apparatus of this invention is related to measuring a flow rate of a liquid having a density .rho. from a vessel having an inner cavity and a pouring channel. A flow sensor introduces a first gas flow into the liquid in the cavity at a first position, the inner cavity having a cross-sectional area A.sub.1 at the first position, and a second gas flow into the liquid in the pouring channel at a second position, the pouring channel having a cross-sectional area A.sub.2 at the second position, there being a vertical distance z between the first and second positions. A transducer provides an output signal proportional to a pressure differential p.sub.1 -p.sub.2 between the first and second gas flows. A processor receives the output signal and determines the liquid flow rate m through the pouring channel according to the proportional relation ##EQU1## where g is gravity.
    • 本发明的方法和装置涉及测量具有具有内腔和倾倒通道的容器的密度rho的液体的流速。 流量传感器在第一位置处将第一气流引入空腔中的液体,内腔在第一位置处具有横截面积A1,在第二位置处将第二气体流入倾倒通道中的液体 ,倾倒通道在第二位置处具有横截面积A2,在第一和第二位置之间存在垂直距离z。 传感器提供与第一和第二气体流之间的压差p1-p2成比例的输出信号。 处理器接收输出信号并根据比例关系通过倾倒通道确定液体流量m,其中g是重力。
