摘要： A resuscitation device including an air delivery device which has two rigid walls moveable toward and away from each other, is substantially rectangular, but may have rounded corners; a scissor type mechanism is employed to maintain parallelism of the walls; optional adjustment means is provided to adjust the delivered volume from at least 1200 ml, for an adult patient to a lesser amount for children and a still lesser amount for infants; the adjustment device may be coordinated with mens for simultaneously adjusting the maximum delivered pressure to levels appropriate to the adult, child, or infant patient; economy in storage and quantity of devices required is achieved.
摘要翻译： 一种复原装置，包括具有可彼此相对移动的两个刚性壁的空气输送装置，其基本为矩形，但可具有圆角; 采用剪式机构来保持壁的平行度; 提供了可选的调节装置，以将输送的体积从至少1200ml调整，对于成年患者，对于儿童来说调节的量更小，并且对婴儿的量更小; 调节装置可以与男士协调，以同时将最大输送压力调节到适合于成人，儿童或婴儿患者的水平; 实现了所需设备的储存和数量的经济性。

摘要： A two zoned grinding wheel is disclosed having a lower section or zone composed of bonded abrasive grain and an upper zone or section made up of bonded particles of a material that is softer than the abrasive grain and therefore less abrasive. The wheel is especially suitable for being held in clamps or a chuck when being used, with the clamps or chuck contacting the wheel on the upper less abrasive section thus greatly reducing wear on said clamp or chuck.
摘要翻译： 公开了一种两个分区的砂轮，其具有由粘合的磨料颗粒组成的下部或区域，以及由比磨料颗粒更软的材料的粘合颗粒构成的上部区域或部分，因此较少的磨料。 该轮特别适用于在使用时保持在夹具或卡盘中，夹具或卡盘在上部磨料部分上接触轮子，从而大大减少了夹具或卡盘上的磨损。

摘要： A grinding wheel is disclosed which is made up of sintered aluminous abrasive and a vitrified bond, the vitrified bond being a frit. A large portion of the sintered aluminous abrasive may be replaced by a non-sintered abrasive and the bond may include fillers and/or grinding aids.
摘要翻译： 公开了一种砂轮，其由烧结铝质磨料和玻璃化粘结构成，玻璃化粘结是玻璃料。 大部分烧结铝质研磨剂可以由非烧结磨料代替，并且该键可以包括填料和/或助磨剂。
