Abstract: An improved cable connector includes a connector insert having an axial bore dimensioned to receive the core of a reinforced cable. A connector body has a substantially cylindrical outer surface and a substantially cylindrical cavity. A distal portion of the cavity is dimensioned to receive the connector insert. A second portion of the cavity proximally displaced from the distal portion is dimensioned to receive the conductor strands of the cable. The connector body may be configured with one or more additional portions of the cavity having progressively increasing diameters, the number of such portions depending on the size of the cable. Alternatively, the inner surface of the cavity may have a slight taper. Using a single die, the connector body is compressed with a swaging tool at several axially spaced-apart locations to grip the conductor strands and also to grip the connector insert.

Abstract: A label for a skein of yarn includes a main portion of generally quadrilateral shape for encircling the skein. A projection is integrally formed with the main portion and extends outwardly from a side of the main portion and is bent to pass through the ends of a loop of yarn formed inwardly of one end of the skein thereby keeping the loop opened. An enlarged tab is integrally formed at an outward end of the projection and is turned downward against the main portion to secure the tab in position through the ends of the loop so that the label resists slipping along the length of the skein.

Abstract: A structured catalyst for selective reduction of nitrogen oxides with ammonia using an ammonia-supplying compound. The catalyst is preferably used for exhaust gas treatment of diesel vehicles powered by diesel motors. The catalyst is characterized by the fact that it contains a reduction catalyst for selective reduction of nitrogen oxides with ammonia and a hydrolysis catalyst for the hydrolysis of urea, where the hydrolysis catalyst is applied in the form of a coating onto the reduction catalyst. By this arrangement of the two catalytic functions in one catalyst the exhaust gas system can be made very compactly and space saving. Moreover, advantageous synergistic effects result from the direct contact of the hydrolysis catalyst and the reduction catalyst.

Abstract: A honeycomb body made from a ceramic material with improved radial pressure resistance that is of cylindrical shape and features a first and a second end face and a cylindrical shell and that is traversed from one end face to the other by axially parallel channels formed by channel walls and distributed across the cross section of the honeycomb body in a regular grid pattern, in which design an outer marginal zone of the honeycomb body, the thickness of which amounts to several channel diameters, encloses a central area. The increase in radial pressure resistance of the honeycomb body is achieved by reinforcing the ceramic material of the cylindrical shell and of the channel walls in the outer marginal zone of the honeycomb body by depositing on or in it one or several inorganic substances for the purpose of increasing its mechanical stability.

Abstract: A process for operating an exhaust gas treatment device in a gasoline engine which is operated mainly with a stoichiometric air/fuel ratio and is operated with a rich-mix air/fuel ratio when accelerating or under full load. The exhaust gas treatment device contains a three-way converter catalyst and a first lambda probe upstream of the catalyst and a second lambda probe downstream of the catalyst. The air/fuel ratio is controlled by using the signal from the first lambda probe, whereas the signal from the second lambda probe is used to check the first lambda probe (trim control) and to diagnose the function of the catalyst. Trim control with the second lambda probe is enabled only when, in the event of rich exhaust gas, the voltage difference between the probe voltage for the second lambda probe and a set point voltage is not larger than a predetermined value.

Abstract: A method for partially coating a cylindrical carrier body with a coating suspension, the carrier body having a cylindrical axis, two end faces, an envelope, and an axial length L, and being provided with a series of channels extending from the first end face to the second end face. A desired coating quantity of the coating suspension is applied onto the carrier body by vertically aligning the cylindrical axis and introducing the coating suspension into the channels through the lower end face. The carrier body, measured from the lower end face, is filled with a filling volume of the coating suspension which is metered, such that the carrier body is only filled up to a height that amounts to a predetermined fraction of its length L. Subsequently, excess coating suspension is removed downward so that the desired coating quantity remains on the carrier body.
