    • The present invention relates to light fast, aqueous, strippable coating compositions containing A) 40 to 90 wt. %, based on resin solids of A) and B), of aqueous polyurethane-polyureas and B) 10 to 60 wt. %, based on resin solids of A) and B), of polymers prepared from radically polymerizable monomers,wherein the percentages of A) and B) add up to 100, based on the weight of resin solids of A) and B). The present invention relates also to substrates coated with these strippable coating compositions. In addition, the present invention relates to the use of the stripped coatings as recycled material by mechanically comminuting the stripped coatings, optionally after cleaning, and then either pressing them in heatable presses to form sheets, or extruding them in an extruder to form endless thermoplastic threads, and then processing the resulting threads by known granulating methods to form cylindrical, spherical, lenticular or rhombic granules. Finally, the present invention relates to the use of the resulting thermoplastic granules for the production of articles by known processes such as injection molding, blow molding, deep-drawing, slush molding or flat extrusion.
    • 本发明涉及一种轻质,含水,可剥离的涂料组合物,其含有A)40-90wt。 %,基于A)和B)的树脂固体,水性聚氨酯 - 聚脲和B)10至60wt。 基于A)和B)的树脂固体,由可自由基聚合的单体制备的聚合物,其中A)和B)的百分比基于A)和B)的树脂固体的重量加到100上。 本发明还涉及涂覆有这些可剥离涂料组合物的基材。 此外,本发明涉及剥离的涂层作为再循环材料的用途,通过机械粉碎剥离的涂层,任选地在清洁之后,然后在可加热的压力机中压制以形成片材,或者在挤出机中挤出以形成环形热塑性塑料 螺纹,然后通过已知的造粒方法处理所得螺纹以形成圆柱形,球形,透镜状或菱形颗粒。 最后,本发明涉及所得到的热塑性颗粒用于通过已知方法如注射成型,吹塑,深冲,搪塑或扁平挤出生产制品的用途。

    • A boat drive has a housing, a tube shaft rotatable in the housing about a shaft axis and having axially opposite front and rear ends, a hub carried on the shaft rear end, and a plurality of radially projecting vanes pivotal on the hub. An axially shiftable core shaft extending coaxially in the tube shaft has a rear end rearward of the tube-shaft rear end and a front end forward of the tube-shaft front end. Mechanism connecting the core-shaft rear end with the vanes pivots the vanes on the hub on axial displacement of the core shaft. A pair of oppositely directed axial-thrust bearings on the core-shaft front end are contained in and surrounded by a hollow piston having front and rear faces axially flanking the thrust bearings. A cylinder fixed in the housing and surrounding the piston forms with the respective faces thereof front and rear compartments so that pressurization of the front compartment shifts the core shaft rearward and pressurization of the rear compartment shifts the core shaft forward.
    • 船体驱动器具有壳体,管轴可围绕轴线旋转并且具有轴向相对的前后端,承载在轴后端上的轮毂和在轮毂上枢转的多个径向突出的叶片。 在管轴中同轴延伸的可轴向移动的芯轴具有管 - 轴后端的后端和管 - 轴前端的前端的后端。 将芯轴后端与叶片连接的机构使芯轴的轴向位移枢转轮毂上的叶片。 芯轴前端上的一对相反方向的轴向推力轴承被中空活塞所包围,并具有轴向侧向推力轴承的前表面和后表面。 固定在壳体中并围绕活塞的圆筒与其前表面和后隔室的相应面形成,使得前隔室的加压使芯轴向后移动,并且后隔室的加压使芯轴向前移动。
