Abstract: A catalyst composition includes a catalytic material containing a platinum catalytic component dispersed on a bulk ceria and a palladium catalytic component; the palla­dium catalytic component may be dispersed either on the ceria or on another support, such as an activated alumina support. The catalytic material, which may include a re­fractory binder, such as alumina, may be dispersed as a washcoat on a suitable carrier, e.g., a cordierite honey­comb-type carrier having a plurality of fine gas flow passages extending therethrough. The bulk ceria may be stabilized with a zirconia stabilizer and/or a lanthana stabilizer. The catalyst composition has utility as an oxidation catalyst and as a three-way conversion catalyst. In the latter case, its activity for the reduction of ni­trogen oxides may optionally be supplemented either by adding a rhodium-containing catalytic overcoat or by pro­viding a catalyst assembly in which the above-described catalyst composition is placed in series with any suitable nitrogen oxides reduction catalyst.

Abstract: The task of conveying devices at the discharge end of extrusion presses is to convey the extruded strands away longitudinally in the direction of extrusion and then convey them transversally in their entire length or in sections. A tried and tested bar conveyor consisting of pairs of endless revolving chains with bars (19, 20) arranged between the latter and supported by the chains is preferably used as a longitudinal conveyor (2). The object of the invention is to shorten the cycle time for the taking over of strands or strand sections from the longitudinal conveyor (2) by the conveying elements (13) of the transverse conveyor and to eliminate the risk of collision between the bars (19, 20) of the longitudinal conveyor (2) and the conveying elements (13) of the transverse conveyor, this object being achieved by virtue of the fact that, over its length, the longitudinal conveyor is formed by interacting individual conveyors (12) of a length which corresponds to the interspace between respectively adjacent conveying elements (13) of the transverse conveyor which lie in the conveying area of the longitudinal conveyor (2). <IMAGE>

Abstract: In a device for use in processing a device input signal carrying a digital symbol sequence, a reception filter filters the device input signal and produces a filter output signal having a high order curvature distortion. The high order curvature distortion results in a predetermined frequency band from adjacent interference on the prdetermined frequency band by other frequency bands adjacent to the predetermined frequency band. Responsive to the filter output signal, an adaptive amplitude equalizing unit equalizes the high order curvature distortion and produces as a first equalized signal. When the device input signal decreases, the adaptive amplitude equalizing unit overestimates the high order curvature distortion to produce intersymbol interference because of appropriately suppressing the other frequency bands by the reception filter. In order to resolve the problem, an adaptive transversal equalizing unit is connected to the adaptive amplitude equalizing unit and equalizes the intersymbol inteference along a time axis of the first equalized signal to produce an output signal with the curvature distortion and the intersymbol inteference suppressed.

Abstract: An electrofusion marker which fuses two pipe sections together and acts as a passive electronic marker. The electrofusion marker includes a tubular thermoplastic fitting having a coil therein, which is temporarily energized by a power supply. This heats the fitting, causing it to fuse with the pipe sections. The coil doubles as an inductor, and a capacitor connected in parallel with the coil creates a resonant LC circuit. After the pipe sections have been fused together and buried, the joint may be thereafter located by emitting a signal into the ground, which is picked up by the resonant circuit and re-radiated. The radiated signal is detected by a receiver, indicating location of the electrofusion marker and joint.

Abstract: A connection assembly secures a running tool into a tubular casing hanger. The connection assembly includes a frusto-conical threaded section (35) on a running tool and a nose section (41) of cylindrical shape located below the threaded section. The casing hanger has a bore (13) with at least one circumferential recess (15,23). A collet ring (47) having internal threads (49) is initially carried on the nose section. The collet ring lands in the recess when the running tool is moved into the casing hanger. Continued mo­vement causes the collet ring to deflect outward. The collet ring has threads on its inner diameter that slide on the threads of the running tool to latch the members together. Slots (65,67)in the collet ring enable the outward deflec­tion to occur. A pin (31) engages the collet ring to enable rotation of the running tool relative to the collet ring to unscrew the members from each other.

Abstract: In order to fill the interior of an insulating glass pane (1) with argon, during pressing of the insulating glass pane (1) one glass pane is held in the region of a corner (2) at a distance from the spacer frame by holding this glass pane at a distance from the spacer frame by swivelling a part (12) of the press plate (11) using suction heads (19, 20) provided on this part (12). Inserted through the gap thus formed are a probe (4) for supplying argon and a probe (5) for extracting air from the interior of the insulating glass pane. The probe (4) through which argon is blown into the interior is aligned parallel to the lower horizontal limb of the insulating glass pane (1), and the other probe (5), via which air or air/argon mixture is extracted, has an opening which points obliquely upwards, i.e. away from the other probe (4). As a result, it is possible to produce insulating glass panes (1) having a filling of the interior other than air without it being necessary to bore holes in the spacer frame, the gas exchange taking place such that argon is mixed with the air displaced from the interior only to a very limited extent.
