摘要： A hand vacuum cleaner is provided comprising a lightweight motor housing containing a revolving brush. A bag assembly is selectively separable from the housing and is sealable to the housing with an elastomeric retaining ring including a sealing and retaining bead for reception in a recessed slot area of a housing bag attachment collar. A fan is mounted to the motor on a motor shaft locking surface including a wall portion tapering towards the fan. The shaft is in locking cooperation with a mating fan bore locking surface including a wall portion tapered for close reception of the motor shaft locking surface. A shaft extension is threadedly received on the motor shaft and is urged into engagement against the fan by resistance of a revolving brush operated by a belt received on the shaft extension which continually tightens the shaft extension to the motor shaft and fixes the fan to the motor shaft. A stone shield is circumferentially spaced about the fan whereby the stone shield blocks items impinging against the housing from the fan from damaging the housing. The housing further includes an air deflector substantially received in the bag assembly having a terminal end portion disposed radially inwardly from the housing outer wall whereby the deflector directs the working air to facilitate greater storage of vacuumed dirt in the bag and prevent heavy objects received in the bag from rolling back into the housing and contacting the fan.

摘要： A method of continuously forming articles having a predetermined, varying cross sectional geometry which comprises continuously introducing molten thermoplastic material from a die opening into a nip formed by opposing rotating rolls with at least one roll having a cooled, arcuate mold cavity in its surface contoured to correspond to each article cross sectional geometry thereby providing varying clearances in the nip, progressively successively arcuately forcing the mold cavity into shaping engagement with the molten thermoplastic material to mold the articles therefrom, maintaining the thermoplastic material containing the articles in contact with one of the rolls after exiting the nip thereby forming a first, curved intermediate shape wherein the thermoplastic material is partially set, immediately passing such shape over a cooled cylindrical surface to further yet not completely set the thermoplastic material and transpose the first shape into a second shape reversely configured from the first shape, discharging the second, shape from the cylindrical surface in a substantially planar direction to straighten such shape and transpose the articles into a substantially flat condition while continuing to set the thermoplastic material, and thereafter separating the articles from the remainder of the thermoplastic material.
摘要翻译：一种连续地形成具有预定的，变化的横截面几何形状的制品的方法，其包括将熔融的热塑性材料从模具开口连续引入到由相对的旋转辊形成的辊隙中，所述辊隙具有至少一个辊，其辊表面的冷却弧形模腔成形为对应于每个制品的横截面几何形状，从而在辊隙中提供变化的间隙，逐渐地连续地弓形地迫使模腔与熔融热塑性材料成形接合以从其中模制制品，保持包含制品的热塑性材料与其中一个辊在离开辊隙之后，形成第一弯曲的中间形状，其中热塑性材料被部分地设定，立即将这种形状通过冷却的圆柱形表面，以进一步而不是完全地设置热塑性材料并将第一形状转置成反向配置的第二形状以第一形状排出第二形状，从大致平面方向的圆柱形表面排出第二形状，以矫直这种形状，并将制品转置成基本上平坦的状态，同时继续设置热塑性材料，然后将制品与其余部分分离热塑性材料。
