Abstract: A CDR circuit arrangement, for example for a transceiver module, features a data recovery unit ( 4 ) for the recovery of the data contained in a received signal (DATA) by scanning this received data signal, and a phase evaluation unit for the determination of a suitable phase position for the scanning carried out by the data recovery unit ( 4 ). The phase evaluation unit comprises a scanning device ( 1 ) for the oversampling of a the received data signal (DATA) in accordance with several different scanning phases (P 0 -P 6 ), a phase detector device ( 2 ) for the evaluation of the scanning values (A 0 -A 6 ) accordingly prepared by the scanning device ( 1 ), in order thereby to derive intermediate signals (UP 1 -UP 3, DN 1 -DN 3 ), which classify the phase error during the scanning of the data signal by the scanning device ( 1 ) in respect of its size and direction of deviation, as well as a filter device ( 3 ), in order to subject the intermediate signals (UP 1 -UP 3, DN 1 -DN 3 ) generated by the phase detector device ( 2 ) to a weighted filtering process. In this situation, a setting signal (DeltaP) is generated by the filter device ( 3 ) for the subsequent regulation and control of the scanning phases (P 0 -P 6 ) of the scanning device ( 1 ).

Abstract: A spring (38) between the sleeve (23) and tube (30) preloads the withdrawal bearing (11) when in use via the driving member (31). The tube contains a recess working with the driving member to hold the sleeve in position for assembly in opposition to the spring, preventing it retracting during the operation. The member can comprise rollers working in radial bores in the sleeve and thrusting a wire ring outwards against the withdrawal bearing during assembly to lock it. The shape of the recess and the pressure exerted by the ring on the rollers are so matched to the axial force of the spring that the sleeve is held in a predetermined position during assembly. ADVANTAGE - Allows use of pre-loaded withdrawal bearing with servo-operated clutch pulled out of engagement.

Abstract: A method is provided for forming a three-layer cladding tube having an outer substrate, a zirconium barrier layer, and an inner liner having alloying elements, in which the zirconium barrier layer (located between an outer substrate and inner liner) is at least partially alloyed with alloying elements that impart resistance to corrosion. The barrier layer has a diffusion layer extending from its inner surface (facing the fuel) to the barrier layer's interior (the interior being defined between the barrier layer's inner and outer surfaces). At the interior edge of the diffusion layer, there will be substantially no alloying elements beyond those normally present in zirconium. The methods of forming such structure include a diffusion anneal of a three-layer cladding in the range of 650 DEG -1000 DEG  C. for times between about 1 minute and 20 hours. This anneal drives some of the alloying elements from the inner liner into the zirconium barrier layer to form the diffusion layer. The exact time and temperature depends upon the fabrication stage at which the heat treatment occurs.
