    • An elevating load platform comprising a base member and a load supporting member interconnected by a linkage means that facilitates vertical movement of the load supporting member generally parallel to the base member, and a plurality of coil springs positioned to urge the load supporting member upwardly relative to the base member so that when the load supporting member is laden the coil springs are compressed, and as the load is progressively removed the coil springs urge the load supporting member upwards to thereby maintain the load supporting member at a desired height, the linkage means comprising a pair of spaced scissor linkages interconnected by a central cross-member, the plurality of compression springs being positioned in a spaced array interposed between the base member and the cross-member.
    • 一种升降装载平台,包括基座构件和负载支承构件,所述负载支撑构件通过联接装置互连,所述联动装置有助于所述负载支撑构件大致平行于所述基座构件的垂直运动;以及多个螺旋弹簧,其被定位成相对于 所述基座构件使得当所述负载支撑构件被所述螺旋弹簧压缩时,并且当所述负载逐渐移除时,所述螺旋弹簧向上推动所述负载支撑构件,从而将所述负载支撑构件保持在期望的高度,所述联动装置包括 一对间隔的剪刀连杆,通过中心横向构件互相连接,所述多个压缩弹簧定位在插入在基座构件和横梁之间的间隔阵列中。

    • A herbicidal composition which comprises at least one carrier and, as active ingredient, a compound of the general formula ##STR1## in which each of n and m independently is 0 or 1; each of Ar.sup.1 and Ar.sup.2 independently is an aryl group, at least one of Ar.sup.1 and Ar.sup.2 being substituted by one or more of the same or different substituents selected from halogen atoms, alkyl groups, alkoxy groups, haloalkyl groups and haloalkoxy groups; and R.sup.1 is hydrogen, or an alkyl, alkylthio or haloalkyl group having from 1 to 4 carbon atoms, and R.sup.2 is hydrogen or a halogen atom provided that at least one of R.sup.1 and R.sup.2 represents a hydrogen atom. Certain compounds of formula I are novel.
