Isolated nucleic acid molecules encoding polysialyl transferases, and the polysialyl transferases themselves are disclosed. SEQ ID NOS: 1, 2, 7 and 8 present examples of these. The nucleic acid molecules and the proteins can be used diagnostically or therapeutically. Additionally, antisense oligonucleotides and antibodies are described, which can also be used diagnostically or therapeutically.

The disclosure illustrates an isolated rocker arm cover for an internal combustion engine. An elongated continuous elastomeric seal element extends from a groove around the periphery of the rocker arm cover. Spring loaded fastener assemblies resiliently hold the cover against the engine with a sufficient force to provide an effective oil seal but still maintain the cover isolated from the engine. The seal element has a configuration assuring a narrow contact area between the ring and the engine.

In a semiconductor integrated circuit consisting of a plurality of semiconductor chips each having a plurality of islands, two or more bonding wires each having different potential are connected to bonding pads formed on the surface of semiconductor chips. The islands are isolated by a dielectric isolation region comprising polysilicon film and isolation film formed in an isolation groove. The polysilicon film is exposed at a dicing line region around the semiconductor chip and a surface of the ...

A pull-type mower conditioner type harvester has a mobile main frame carrying a vertically adjustable header or subframe which carries a plurality of harvesting components that extend between the opposite sides of the header, including a reciprocating sickle type cutter bar. The cutter bar includes a transverse support member that spans the width of the header and carries the cutter bar components, including a wobble type drive at one end of the cutter bar. The cutter bar is connected to the hea...

A photosensitive integrated circuit switch that operates in the same manner as back-to-back photosensitive SCR's. The invention combines the monolithic, junction-isolated construction of the basic photrac, described in U.S. Pat. No. 3,918,083, and the operational characteristics of a dielectrically isolated photrac, described in co-pending application Ser. No. 616,040, but incorporates the single-quadrant gate-triggering feature of the latter. Its simplified construction makes it advantageous in...

A strap for mounting an electrical wiring device in a mounting box comprises a yoke member having laterally projecting tabs on each end thereof, the tabs being fastened to the mounting box. A pad of electrically insulating material is positioned upon the tab so as to be interposed between the tab and the mounting box when the strap is mounted. The tab and pad are each provided with a slot through which a mounting screw passes, and the portion of the pad defining the slot has a beveled aperture w...

The present invention relates to an isolated bacterial reverse transcriptase. The reverse transcriptase synthesizes a peculiar RNA-DNA complex called msDNA which is a single-stranded DNA structure branched out from an RNA molecule. The gene coding for the reverse transcriptase has been isolated and sequenced. It codes for a polypeptide of 485 amino acid residues. This is the first time that a reverse transcriptase has been found, identified and isolated from a prokaryotic microorganism of which ...

A motion transmitting remote control cable assembly (10) comprises a motion transmitting core element (12) having a terminal (14) attached to one of its ends, where the terminal includes a passageway (16). The assembly also includes a socket member (20) disposed in the passageway for interconnecting the core element (12) with a control element (18). The assembly (10) is characterized by including a separate isolator (22,22') interposed in the passageway (16) between the socket member (20) and th...

A vibration isolated shift lever comprises a control lever, a shift plate, a transmission plate, a transmission lever and resilient bushings located between the shift plate and transmission plate. The shift plate triangularly shaped and is provided with three shift plate apertures one being located at each of the apexes of the triangular shift plate. The transmission plate provided with a transmission lever receiver that is bolted to the transmission lever. The transmission plate is triangularly...

A field shield isolated transistor is provided wherein the left-hand edge (E1) of a left-hand contact pad (51a) is positioned a distance (d5) to the right of the left-hand edge (F1) of a left-hand field shield gate electrode (41); the right-hand edge (E2) of the left-hand contact pad (51a) is positioned a distance (d6) to the right of the right-hand edge (F2) of the left-hand field shield gate electrode (41); the left-hand edge (E3) of a right-hand contact pad (52a) is positioned a distance (d7)...
