摘要： A frame element, especially for window and door construction, which is formed as a composite member with a hollow metallic profile member covered by a sheath of synthetic resinous material. The sheath includes mounting lugs and grooves for directly supporting window or door members. The hollow metal profile is provided with outer flanges formed as extensions of side walls of the member, which flanges serve to provide a rigid support base for supporting the loads applied to the frame element by way of the sheath. Interlocking groove and strip connections are provided on the sheath and the profile member at the corners formed respectively between the outer flanges and the immediately adjacent joining side wall of the profile member. These interlocking groove and strip connections assure an elastic, resilient seating of the plastic sheath against the outer confines of the profile member over the entire surface of the profile member.
摘要翻译：一种框架元件，特别是用于门和门结构，其形成为具有由合成树脂材料的护套覆盖的中空金属型材的复合构件。护套包括用于直接支撑窗户或门构件的安装凸耳和凹槽。中空金属型材设置有形成为构件的侧壁的延伸部的外凸缘，该凸缘用于提供刚性支撑基座，用于支撑通过护套施加到框架元件的负载。在护套和轮廓构件上，分别在外凸缘和轮廓构件的紧邻的接合侧壁之间形成的角部设置有联锁槽和带连接件。这些互锁槽和条带连接件确保了塑料护套的弹性的弹性座位，在轮廓构件的整个表面上抵靠轮廓构件的外部限制。

摘要： Apparatus for automated polyelectrolyte measurement of liquid process materials including a sample vessel which defines an electrically insulating, cylindrical cavity below a larger-diameter reservoir. Electrodes are located at the ends of the cylindrical cavity and an insulating piston is reciprocated with a predetermined, small clearance within the cavity. The charge displacement is measured between the electrodes. An outlet channel opening at the floor of the cylindrical cavity is connected to an outlet pipe. A rinsing duct with valve control for introducing a rinsing fluid into the reservoir. A controller is connected to an actuator for reciprocating the piston, to a valve in the outlet pipe and to the rinsing valve. After each polyelectrolyte measurement the substance under test is removed from the sample vessel through the outlet channel, rinsing fluid is introduced, and the rinsing fluid is removed through the outlet channel while the piston reciprocates. The reciprocation of the piston provides a pumping action which is used to expel the substance under test and enables effective rinsing and cleaning of the apparatus with no need for manual intervention.
摘要翻译：用于液体处理材料的自动聚电解质测量的装置，包括在大直径贮存器下方限定电绝缘的圆柱形空腔的样品容器。电极位于圆柱形腔的端部，并且绝缘活塞在空腔内以预定的小间隙往复运动。在电极之间测量电荷位移。在圆柱形腔的地板处的出口通道开口连接到出口管。具有阀控制的冲洗管道，用于将冲洗流体引入储存器。控制器连接到用于使活塞往复运动的致动器，连接到出口管中的阀和冲洗阀。在每个聚电解质测量之后，通过出口通道将样品从样品容器中取出，引入冲洗流体，并且当活塞往复运动时通过出口通道去除冲洗液。活塞的往复运动提供了一种泵送动作，用于排出被测物质，能够有效地冲洗和清洁设备，无需手动干预。
