    • Improved apparatus and method are provided for the dispensing of particulate material from the gravitationally bottom discharge mouth of a hopper. In a presently preferred form, the particulate material moves downwardly first through a conically sided zone to a toroidally-configured aperture, and, after passage therethrough, moves downwardly through a cavity that preferably has a cross-sectionally circular perimeter. Centrally upstanding in the cavity is a body with preferably conically diverging sides over which the particulate material moves downwardly to a cover plate or deck which has a circumferentially extending discharge opening through which the particulate material is discharged. Most preferably, the body also extends upwardly through the aperture and through the conically sided zone. Particulate material downward movement and discharge is produced by shaking, preferably vibration, of the deck. A presently preferred particulate material is fish feed. The apparatus and method avoid particulate material bridging and hang-up and provide the capability for achieving uniform dispensing rates generally independently of the fill level of particulate material in the hopper.
    • 提供改进的装置和方法用于从料斗的重力底部排出口分配颗粒材料。 在目前优选的形式中,颗粒材料首先通过圆锥形侧面区向下移动到环形构造的孔,并且在通过之后,向下移动通过优选具有横截面圆形周长的空腔。 在空腔中中央竖立的是具有优选锥形发散侧的主体,颗粒材料在该主体上向下移动到具有周向延伸的排放开口的盖板或甲板,颗粒材料通过其排出。 最优选地,主体还向上延伸穿过孔并穿过圆锥形侧面区域。 颗粒材料向下运动和排放是通过摇动,优选地振动的。 目前优选的颗粒材料是鱼饲料。 该装置和方法避免了颗粒材料的桥接和悬挂,并且提供了通常独立于料斗中的颗粒材料的填充水平实现均匀分配速率的能力。

    • Apparatus for feeding poorly flowable dry particulate materials includes a rotary supply hopper having an interior chamber for receiving and containing a quantity of material and an annular sidewall open at a lower edge, a stationary platform having a circular groove formed in a top surface of the platform encircling an upright central axis and an opening extending through the platform adjacent to the circular groove, spaced from the central axis and defined between the circular groove and central axis, a support structure supporting the hopper above the platform to undergo rotation relative to the platform about the upright central axis with the lower edge of the supply hopper being spaced from and extending downward into the circular groove of the platform such that the platform serves as a stationary bottom for the rotary supply hopper, and an annular discharge spout attached at an open upper end to the platform below and encircling the opening through the platform and having a transfer passage extending from the open upper end to an open lower end so that material can undergo gravity-assisted flow downward through the platform opening and discharge spout passage for discharge at the open lower end of the discharge spout. The apparatus also includes a stripper blade rotatably mounted to the discharge spout and extending radially inward across the open lower end thereof for engaging discharging material to assist its movement away from the open lower end of the discharge spout.
    • 用于供给不良流动干燥颗粒材料的设备包括旋转供料料斗,其具有用于接收和容纳一定量材料的内部室和在下边缘开口的环形侧壁,具有形成在平台的顶表面中的圆形槽的固定平台 环绕直立的中心轴线和与该圆形槽相邻的平台延伸穿过平台的开口,与中心轴线间隔开并限定在圆形槽和中心轴线之间;支撑结构,其支撑在平台上方的料斗以相对于平台围绕 供应料斗的下边缘的直立中心轴线与平台的圆形槽间隔开并向下延伸到平台的圆形槽中,使得平台用作用于旋转供料料斗的固定底部,以及附接在开口上部的环形排出喷嘴 结束到平台下面,并通过平台环绕开口,并具有一个转动 从打开的上端延伸到开口的下端,使得材料可以经受重力辅助的流动,通过平台开口和排出喷口通道,以在排放口的开口下端排出。 该设备还包括可旋转地安装到排出口并且沿其开口的下端径向向内延伸的剥离器叶片,用于接合排出材料以帮助其移动远离排放口的敞开的下端。

    • Apparatus and method for containing and feeding particulate material tending to pack into a mass from an elongated hopper having opposed sloping walls converging downward and inward towards each other to terminal margins presenting between them an elongated laterally restricted outlet for directing material onto a conveyor below. Gates are provided to close the outlet for containing the material and to open the outlet to discharge it onto the conveyor belt. Baffles within the hopper are provided to divide the cargo at a level spaced above the outlet into several piles which merge above and below the outlet. In this way the material is channelled to the outlet so that lateral arches which may be formed in the material are prevented or broken up to assure feeding. Pressure may be relieved on some of the piles by flanges extending laterally of the baffles. The invention also includes the combination of gates equipped to break up longitudinal arches with baffles to prevent the formation of lateral arches.
    • 用于容纳和进料的微粒材料的装置和方法,所述颗粒材料倾向于从具有相对的倾斜壁的细长料斗包装成块,所述相对的倾斜壁朝向彼此向下并向内收敛,以在其间呈现的端部边缘之间延伸有用于将材料引导到下面的输送机上的横向受限的出口。 提供盖以关闭用于容纳材料的出口并打开出口将其排出到输送带上。 提供料斗内的挡板,以将出口间隔开的水平分隔成几个在出口上方和下方合并的桩。 以这种方式,材料被引导到出口,使得可以形成在材料中的侧向拱被防止或分解以确保进料。 压力可以通过在挡板的侧面延伸的凸缘在一些桩上减轻。 本发明还包括装配有用于将纵向拱门与挡板分开以防止形成横向拱门的组合。

    • For measuring the proportion or quantity of a component in a radiation-transparent mixture, a beam is passed through the mixture and subsequently split by a beam splitter into a measuring beam and a reference beam. The measuring beam is passed through a narrow-band interference filter which has a transmitting wavelength that corresponds to a discrete absorption wavelength of the component. This filter is oscillated in a range of oscillation which traverses the absorption maximum. The reference beam is passed through a narrow-band interference filter which has a transmitting wavelength that differs from the absorption wavelength of the component. Subsequently, the radiation intensities of the measuring beam and the reference beam are separately detected and their difference is formed. This difference is a function of the proportion or quantity of the component.
    • 为了测量辐射透明混合物中组分的比例或数量,将光束通过混合物,然后由分束器分裂成测量光束和参考光束。 测量光束通过窄带干涉滤光片,窄带干涉滤光片具有对应于部件离散吸收波长的透射波长。 该滤波器在穿过吸收最大值的振荡范围内振荡。 参考光束通过窄带干涉滤光片,该滤光片具有不同于部件的吸收波长的透射波长。 随后,分别检测测量光束和参考光束的辐射强度,并形成它们的差异。 该差异是组分的比例或数量的函数。
