Abstract: The present invention relates to isolated DNA coding for the restriction endonuclease  Sca I as well as to a method for cloning methylase genes from  Streptomyces  into  E.coli  by a modification of the methylase selection method. At first, the standard methylase gene selection method was tried to clone the  ScaI  methylase gene using a high-copy-number cloning vector pUC19 during library construction. The  ScaI  methylase gene was refractory to cloning by using pUC19, presumably due to the poor expression of the  ScaI  methylase gene in  E.coli . If the  ScaI  methylase is not efficiently expressed in  E.coli , the  ScaI  sites on the plasmid will not be sufficiently modified by the methylase. As a consequence, the plasmid will be cleaved and lost in the plasmid library after  ScaI  endonuclease challenge. Since the standard methylase selection did not work, the "endo-blue method" was tried to clone the  ScaI  endonuclease gene. Nineteen blue colonies were identified, but none of them yielded any detectable  ScaI  endonuclease activity. The  Sca I endonuclease gene was first cloned by inverse PCR using primers that annealed to the end of the  Sca I methylase gene. In order to increase the  Sca I endonuclease expression in  E. coli  , an optimal ribosome binding site and spacing were engineered in front of the ATG start codon and the gene was inserted into expression vector pRRS.

Abstract: A tunneling ferrimagnetic magnetoresistive sensor (10, 30, 110) that has a - R/R  greater than that of known magnetoresistive sensors, and that, with appropriate electrode materials, can undergo a substantial change in resistance in response to a magnetic field in the intensity range of 10s of Oe, which is typical of the intensity of the magnetic fields encountered in magnetic recording media such as discs and tapes. The tunneling ferrimagnetic magnetoresistive sensor is composed of a stack of thin-film layers that include a layer (12) of a ferrimagnetic material, a layer (14) of a magnetic material, and a layer (16) of an insulator interposed between the layer of the ferrimagnetic material and the layer of the magnetic material. The ferrimagnetic material is conductive. The magnetic material is also conductive and has a coercivity substantially different from that of the ferrimagnetic material. The insulating layer is of a thickness that is sufficiently small to permit tunneling of current carriers between the layer of the ferrimagnetic material and the layer of the magnetic material.

Abstract: There is disclosed an apparatus for installing a
channel-shaped sealing or finishing strip on a mounting
flange, the strip being generally channel-shaped in
cross-section but with the side walls of the channel
initially splayed apart to facilitate mounting. The
apparatus comprises a head portion and a pair of
rollers mounted for rotation on the head portion. The
rollers define between them a gap of such predetermined
distance as to enable them to apply pressure to the
splayed-apart side walls of the channel so as to close
those side walls towards each other as the head portion
is moved along the length of the flange, whereby the
side walls of the strip move into a subsequently
retained configuration in which they embracingly grip
the flange. The head portion comprises first and
second housings each of which carries a respective one
of the said rollers, and said first and second housings
are movable relative to each other to alter the width
of the said gap against a biasing means which tends to
urge the said housings in a direction to close the said
gap. In addition, the apparatus comprises a prising
means operable to prise the first and second housings
apart to widen the gap and thereby permit the tool to
be mounted on the strip. 
     A method of using the tool to fit a sealing strip
onto a flange is also disclosed.
