摘要： The invention relates to a sanitary tub with an outer shell made of steel sheet, an inner shell made of plastic, and an intermediate layer connecting the two shells. A protective coating is applied to the outer shell to protect against corrosion. The outer shell is provided with a coating applied to both the inner and outer sides. This coating consists of a conversion layer produced by phosphatizing, and a lacquer forming on the outer side the abrasion and impact resistant protective coating. On the inner side of the shell an agent effectively imparts adhesion between the steel sheet and the intermediate layer without mechanical roughening.

摘要： A method for producing a composite bathtub having at least one steel shell and at least one acrylic shell which are solidly joined to each other. A deep-drawn acrylic blank is first reverse-drawn over a core. An outer shell mold is then placed over the acrylic blank, at a certain distance from the acrylic blank. Once the outer shell mold and the acrylic blank are sealed off from each other, a reaction resin is injected into the space between the two shells. After the reaction resin has set, the outer shell mold is removed and the steel blank is positioned. The space between the steel blank and the acrylic blank is re-sealed and a polymer foam is injected into this intermediate space. Once the polymer foam has cross-linked, the composite bathtub is complete. One advantage of the method of this invention is that the acrylic shell and the steel exterior of the composite bathtub do not have to be identical in shape.

摘要翻译： 一种复合浴缸的制造方法，该复合浴缸具有至少一个钢壳和至少一个丙烯酸酯壳体，它们彼此牢固地接合。 深冲压丙烯酸坯料首先在核心上反向拉伸。 然后将外壳模具放置在丙烯酸坯料上方，距离丙烯酸类空白处一定距离处。 一旦将外壳模具和丙烯酸树脂坯料彼此密封，则将反应树脂注入到两个壳体之间的空间中。 在反应树脂固化后，除去外壳模具并定位钢坯。 将钢坯和丙烯酸坯料之间的空间重新密封并将聚合物泡沫注入该中间空间。 一旦聚合物泡沫交联，复合浴缸就完成了。 本发明的方法的一个优点是复合浴缸的丙烯酸酯外壳和钢外壳的形状不一定相同。

摘要： A jogger for lateral alignment of sheets in a sheet-delivering device of a sheet-processing machine, such as a printing machine, has displaceable diaphragm; resiliently yieldable member; and a pusher member connected with the diaphragm and the resiliently yieldable member so that upon displacement of the diaphragm in one direction, the pusher member first moves toward a sheet-delivery device against the force of the resiliently yieldable member and then tilts after contacting a sheet stack in the sheet-delivery device, wherein the diaphragm is elastic and pneumatically impingeable to perform the displacement, so that the pusher member automatically adjusts upon the sheet stack.

摘要： A process for producing deformable acrylic panels with increased resistance to abrasion and scratching preferably for sanitary articles to be produced by the deep-drawing process. Immediately prior to the deep-drawing step, a type of lacquer is applied to an acrylic panel. The lacquer contains dispersed nanoscale particles preferable of an inorganic material. The semifinished acrylic panel is heated and subsequently deep-drawn. The lacquer coating is applied to the semifinished acrylic panel with the help of rollers or a doctor blade. In addition, the lacquer coating can be applied by immersing or flooding the semifinished acrylic panel.

摘要： Grippers pull the leading ends of sheets along a sheet transport path, and a guidance structure facilitates sheet travel. The guidance structure comprises a plurality of longitudinally extending guide bars provided with suction openings, the ribs spaced apart transverse to the sheet-transport direction. Intermediate the bars are large-surface-area plates having suction openings. When guiding sheets printed on only one side, the intermediate suction plates are at about the same level as the longitudinally extending guide bars, and the entire face of the sheet is engaged, with the help of suction force. When guiding sheets printed on both sides, the imtermediate suction plates all drop down out of contact with the sheet, leaving only the spaced apart and narrow longitudinal guide bars to engage the sheet. The guide bars are furthermore transversely shiftable, so that they can be brought into engagement with parts of the sheets bearing no printing.

摘要翻译： 夹具沿着纸张传送路径拉动纸张的前端，并且引导结构便于纸张行进。 引导结构包括多个纵向延伸的引导杆，其设置有抽吸开口，肋横向于纸张传送方向间隔开。 中间棒是具有抽吸口的大表面积板。 当仅引导印刷在一侧的纸张时，中间吸板处于与纵向延伸的导杆大致相同的高度，并且借助于吸力将片材的整个面接合。 当引导印刷在两面上的纸张时，中间吸板全部脱落而不与片材接触，仅留下间隔开且狭窄的纵向导杆来接合片材。 引导杆还可以横向移动，使得它们可以与不打印的片材的部分接合。
