    • A corn harvesting implement for a field chopping machine has a drawing-in trough, a plurality of transporting passages supported on the drawing-in trough, the transporting passages including at least two outer transporting passages which are foldable upwardly to a transporting position for obtaining a smaller transporting width and foldable outwardly to a working position. The transporting passages also include stationary transporting passages. The transporting passages are arranged so that in the working position a predetermined distance is provided between at a part of at least one of the upwardly foldable transporting passages and at least a part of a neighboring part of the stationary transporting passages. Means for increasing the distance at least before a beginning of folding the upwardly foldable passages from the working position to the transporting position is provided.
    • 一种用于田间切碎机的玉米收割机具有一个拉入槽,多个输送通道,支撑在拉入槽上,输送通道包括至少两个外部输送通道,该外部输送通道向上折叠到输送位置,以获得一个 较小的运输宽度并可向外折叠到工作位置。 运输通道还包括固定运输通道。 传送通道被布置成使得在工作位置中,至少一个可向上折叠的传送通道和固定传送通道的相邻部分的至少一部分之间设置预定距离。 提供至少在将向上可折叠的通道从工作位置折叠到运送位置的开始之前增加距离的装置。

    • A filter pack for the purification of air and gases comprises an undulating sheet of elastic fleece, e.g. one made from polyester fibers, sandwiched between two sets of similarly folded parallel retaining strips interspersed with the undulations of the sheet so that each strip forms a plurality of integrally interconnected U-shaped pleats with the legs of adjacent pleats closely juxtaposed. The strips, or at least outer surface layers thereof, consist of heat-fusible material enabling the closely juxtaposed legs of their pleats to be thermally bonded together after pleating. The strips may also be made from fleece so that bonding takes place only at contact points between their fibers, allowing the filtered fluid to pass both between and through the strips. Similar bonding may take place between the strips and the sheet.
    • 用于净化空气和气体的过滤器组件包括起伏的弹性羊毛片,例如。 由聚酯纤维制成的,夹在两组相似的折叠的平行的保持条之间,散布着片材的起伏,使得每个条带形成多个整体互连的U形褶皱,相邻褶皱的腿紧密并置。 条带或其至少外表面层由热熔材料组成,使得其褶皱的紧密并置的腿在打褶之后热粘合在一起。 条带也可以由羊毛制成,使得仅在它们的纤维之间的接触点进行粘结,允许经过滤的流体在条带之间通过。 在条和片之间可能发生类似的粘结。
