IPC: B01L3/00
Filed: 1989-06-19
Abstract: Reaction vessel and process for the quantitation of the state or of changes of state of inhomogeneous samples with a liquid phase and one of several solid phases. The samples are introduced into reaction vessels (1), preferably in the form of a microtitration plate, and then guided through a light beam (3). Thereafter, they are analyzed by vertical photometry. The reaction vessels (1) used have rectangular base areas (2). The light beam (3) completely illuminates the base area (2) of the reaction vessels (1) in several separate sections (2').

Abstract: A tamping pad includes cutout along the length of the leading edge thereof to support at least one wear-resistant insert rigidly positioned therein. The wear-resistant insert comprises a body having a first side and a second opposed side, first and second opposed major surfaces and first and second opposed shoulders. The first side of the insert body defines a tamping blade leading edge which is arcuate in shape between the opposed shoulders. The arcuate leading edge of the insert body has a radius which defines the length of the arcuate edge to be of a ratio of about 1.3 relative to the width of the carbide insert. Preferably, the plurality of inserts extends end to end along the length of the leading edge of the blade to define the interrupted leading edge of the tamping pad as formed by the curvilinear leading edge of each of the plurality of inserts.

Abstract: In a construction made of prestressed concrete, a free space (1) is provided around a prestressed tendon (3). The sheath is removed from the exposed prestressed tendon (3), and in its place a sliding sleeve (2) is fitted. An adhesive and/or filling compound (5) is injected in the gap between the sliding sleeve (2) and the prestressed tendon (3). A rotatably mounted coil shell (4) is then placed on the sliding sleeve (2). The coil shell (4) has, laterally, a toothed ring (6) which serves for setting the coil shell (4) in rotation by means of a transmission (7) by an electric motor (11) with output drive (12). The coil shell (4) can thus be wound with a copper wire (14) from a supply coil (13). The method permits prestressed concrete constructions which already exist to be retrofitted with corresponding measuring coils. <IMAGE>
