    Abstract: A depolarizer includes a second birefringent plate having a thickness which continuously changes in a direction of an optical axis of the second birefringent plate; and a third birefringent plate having a thickness which continuously changes in a direction of 45 degree with respect to an optical axis of the third birefringent plate; wherein the second birefringent plate is stuck on the third birefringent plate so that a reduction direction of the thickness of the second birefringent plate and a reduction direction of the thickness of the third birefringent plate are opposite to each other.

    Abstract: A drum rotatable about an axis through its center of gravity carries troughs located in a circle concentric to said axis and which are charged at a certain level with flowing material to be measured as to quantity, whereby the drum is influenced by a driving moment from the weight of the charged material. After a certain rotation of the drum, the troughs discharge the charged material at a lower level than said charging level. Means are provided for counteracting rotation of the drum by said driving moment, said means including interconnected scoops arranged in a circle concentric to an axis through the common center of gravity of the scoops, said last axis forming an angle with a vertical line. The drum rotates the scoops around said last-mentioned axis, and the scoops successively elevate a second material from a certain level and discharge it at a higher level. The drum forms a closed chamber containing a certain amount of the second material, and the scoops are located on the inside of the drum within said chamber, whereby an accurate measurement of the weight of the flowing material is effected regardless of changes in the density of the material.

    Abstract translation: 可绕其重心旋转的滚筒可承载位于与所述轴线同心的圆中的槽，并且以一定数量的流动材料将其以一定的水平进行测量，由此滚筒受到来自 带电材料的重量。 在鼓的一定旋转之后，槽以比所述充电水平低的水平对充电材料进行放电。 提供了用于通过所述驱动力矩来抵消滚筒的旋转的装置，所述装置包括通过勺子的共同重心以与轴为中心的圆形排列的相互连接的勺子，所述最后的轴线与垂直线形成一角度。 鼓围绕所述最后提到的轴旋转勺子，并且勺子连续地将第二材料从一定水平升高并将其以更高的水平排出。 鼓形成包含一定量的第二材料的封闭腔室，并且勺子位于所述腔室内的滚筒内侧，由此实现流动材料的重量的精确测量，而不管密度 材料。

    Abstract: A container is mounted in an enclosure for movement along a fixed path. The enclosure has an outlet connected to a suction line, such as a pump, and an inlet is arranged to discharge liquid into the container. The container is moved along the path by the weight of the liquid accumulating in the container. The container is provided with discharge means which functions automatically to increase the volume of liquid discharged from the container, the arrangement being such that the discharge is equal to the flow of liquid into the container, whereby the container is moved to a position proportional to the volume of the flow of liquid into and out of the container. Position indicating means is actuated by the container to indicate the position thereof at all times, thus indicating the flow of liquid through the meter. The container discharge means is adjustable exteriorly of the enclosure to accurately indicate the flow of liquids of different densities.
