Title: A universal joint and bidirectional overrunning clutch assembly
Inventor: ITO KENICHIRO
IPC: B60K17/34
Filed: 1992-04-29
Abstract: A driving force transmission device for a four-wheel drive vehicle has a homokinetic joint (2) having an outer ring (5) and a clutch device (3) having an outer ring (6) coupled to the outer ring of the homokinetic joint. An input shaft (14) is rotatably inserted in the outer ring (6) of the clutch device (3). A cage (17) is rotatably mounted between opposed surfaces (15, 16) of the outer ring (6) and the input shaft (14) and has pockets (19) in which sprags (21) are mounted. The sprags engage the opposed surfaces (15, 16) when the input shaft and the cage rotate relative to each other either clockwise or counterclockwise. Springs (22) bias the sprags towards a disengaged position. A pin (26) couples the cage (17) and the input shaft (14) together for rotation with a degree of relative rotation therebetween and a member (30) coupled to the cage or the input shaft produces relative rotation therebetween to control the operation of the engaging elements (21). <IMAGE>

Title: Glycoprotein encoded by a human endogenous retrovirus K envelope gene
Inventor: DIERICH MANFRED P
IPC: C12N15/48
Filed: 1992-11-10
Abstract: By means of a polymerase chain reaction a 1053 bp DNA segment from the putative outer membrane part of the human endogenous retrovirus (HERV)-K-envelope gene was amplified. A 959bp part of the amplified DNA was inserted into the pAX-bacterial-expression-vector. A recombinant fusion protein of a HERV-K-envelope-portion with * small Greek beta *-galactosidase was obtained. A monoclonal antibody was generated which recognizes the envelope portion of the fusion protein (FP). This mAb is capable of immunoprecipitating a 67kD glycoprotein from the human breast carcinoma cell line T47D, the amount of which is strongly enhanced after stimulation with estradiol/progesterone. The same band could be precipitated from other carcinoma cell lines (Hep2, MCr7 and HELA), but not from the human B-lymphoblastoid cell line Raji and the mouse myeloma cell line Ag8.653. The data suggests that the antigen recognized by the anti-HERV1 mAb is the translational product of an active HERV-K-env gene or whole HERV-K provirus.
