摘要:
A coupling assembly for optionally connecting a driving axle in a motor vehicle having multiple driving axles is disclosed. The coupling assembly comprises an externally controllable friction coupling with a coupling input part and an output part. The input part is rotatingly drivable around an axis of rotation A. A differential drive with an input element and two output elements which are drivingly connected to the input element, are also included. The input element of the differential drive is arranged coaxially relative to the coupling output part and drivably connected to the coupling output part for the purpose of transmitting torque. A driveline assembly having such a coupling assembly is also disclosed.

An expansion joint system (10) traverses a slot (12) between concrete slabs (14, 16). The system includes nosings (32, 34) overlying an expansible member (40) of unitary construction and made from resilient material. The expansible member has ribbed flaps (42, 44) with holes (48) therethrough. The flaps are attached to the slabs by a layer (46) of adhesive bedding material. The expansible member includes a first segment (69), a second segment (82) and a third segment (96). The segments each include pad portions (70, 84, 98), and web portions (78, 92, 102) extending downward from the pad portions into the slot. The adjacent web portions are joined at locations (106, 112) vertically below the pad portions of the segments.

The invention relates to a drive assembly for a motor vehicle with a drive unit and multiple driven axles. The drive assembly comprises a transfer case 12 which distributes torque introduced by the drive unit 4 to a first driveline 5 and to a second driveline 7, wherein the first driveline 5 is permanently drivingly connected to the transfer case 12 in order to transfer torque to a first driving axle 6 and wherein optionally, in addition to the first driveline 5, the second driveline 7 can be drivingly connected to the transfer case 12 in order to transfer torque to the second driving axle 8, and a propeller shaft 24 which is arranged in the torque flow between the transfer case 12 and the second driving axle 8, wherein there are provided first coupling means 22 for coupling and uncoupling the propeller shaft 24 relative to the drive unit 4, as well as second coupling means 26 for coupling and uncoupling the propeller shaft 24 relative to the second driving axle 8.

A differential drive with a rotatably arranged differential carrier (11) in which a multi-plate coupling (23) is arranged so as to be effective between the differential carrier (11) and a sideshaft gear (29), wherein the differential carrier (11) includes a dish-shaped carrier part (12) in which there are received sideshaft gears (28, 29) and differential gears (26, 27). The differential carrier includes a dish-shaped cover (14) which receives the plates of the multi-plate coupling (23).
摘要:
The invention provides hyperactive mutant recombinases and hybrid mutant recombinases, and methods for their identification. Also provided are nucleic acids encoding hyperactive mutant recombinases and hybrid recombinases, as well as vectors and host cells. Host cells include eukaryotic cells capable of expressing said recombinases and carrying out site-specific recombination in the cell. The mutant recombinases may be used, for example, in biotechnology, gene therapy or transgenic applications.
摘要:
An assembly for precisely positioning a pair of die members beneath a reciprocating press ram, wherein a clamping assembly extends between each die member and a frame supported on a bed of the press for clamping and unclamping the die members. A self-lifting assembly provides a force which bears downwardly against the frame and upwardly against the die members for appreciably reducing frictional contact therebetween. An adjustable key is positioned for aligning the frame beneath the reciprocating ram. Finally, positioning apertures are provided for aligning the die members relative to one another on the frame.

The invention provides assays that can detect multiple genetic variants of a gene (e.g., a mycobacterium gene) in a sample using a pool (using 2, 3, 4, or more) of oligonucletide hybridization probes.

An expansion joint sytem (10) spans a slot (12) of adjacent concrete slabs (14, 16). The system includes a boxed out area (22) adjacent the slot. A plate member (32) extends across the slot. A preformed resilient pad (42) is positioned above the plate member. Nosings (64) of resilient material are bonded to the pad and to the surfaces bounding the boxed out area. The pad has a cross sectional configuration that achieves enhanced bonding to the nosings, greater flexibility and resistance to failure in cold weather, and greater elongation without failure.
