Abstract: The shaker comprises a support frame having rods extending in spaced parallel relation longitudinally thereof. A shaker table and a separate bracket are supported, at respective longitudinally spaced points, on said rods for rectilinear reciprocation along the rods. The shaker table is arranged to have a carrier, for articles to be shaken, secured thereto, and a counterweight is secured to the bracket. A pair of timing belts extend around respective gears adjacent opposite ends of the support frame, and the shaker table is secured to the upper run of the belts, with the bracket and the counterweight being secured to the lower run of the timing belts. An adjustable stroke crank means, driven by a motor or the like, oscillates driving gears engaged with the timing belt so that the shaker table and the bracket with the counterweight are reciprocated longitudinally of the rods through equal amplitudes and in respective opposite directions. Thereby, during operation of the shaker, the counterweight substantially balances the shaker table.

Abstract: A filtration apparatus for simultaneously performing a plurality of filtering operations. A plurality of filters are respectively situated beneath a plurality of reservoir cavities for supplying liquid to be filtered to the filters to pass therethrough, and a plurality of collection vials are respectively situated beneath the filters for receiving the filtrate therefrom. The entire apparatus can be inverted as a unit. A plurality of seals respectively seal the reservoir cavities with respect to the filters in such a way that during the washing operations washing liquid can wash the margins of the filters.

Abstract translation: 一种用于同时执行多个过滤操作的过滤装置。 多个过滤器分别位于多个储存器腔下方，用于将待过滤的液体供给到过滤器中以通过，并且多个收集瓶分别位于过滤器下方以从其中接收滤液。 整个装置可以作为一个单元反转。 多个密封件相对于过滤器分别密封储存器腔，使得在洗涤操作期间，洗涤液体可以洗涤过滤器的边缘。
