Abstract: Title of the Invention:       Overlapped Plated Steel Strip for Making Anticorrosive Double Wall Steel Pipes Abstract of the Disclosure:         A double wall small diameter steel pipe so far obtained from a steel strip is made by using a steel strip copper-plated on both side surfaces or one side surface.  The double wall steel pipe thus made is provided with a plating layer on each or either of the inside and outside surfaces.          However, the copper-plated layer applied to obtain such double wall steel pipe is poor in the anticorrosion and is desired to be improved in the anticorrosion today.         The present invention is made by providing an over-lapped plated layer having a plated layer consisting of an Ni base - Cu alloy as a lower layer and a plated layer con-sisting of copper or a Cu base - Sn alloy as an upper layer on each or one of both side surfaces of a steel strip.  Ac-cording to the present invention, a double wall steel pipe having a coating higher in the anticorrosion than an Ni base -Cu alloy layer which is high in the anticorrosion but has not been so far used because its melting point is high can be obtained at or below the same temperature as in the conven-tional method.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to the joining of optical fibre cables.  The ends  of two optical fibres being joined together must be very precisely aligned in order to minimize losses, at the coupling or joint in the signal being trans-mitted by the channel which comprises the two coupled fibres. Various connections and joining methods are known for effecting such precise alignment, but in general they are expensive and intricate and require an operator having a high degree of skill.  The present invention provides an optical fibre cable joint comprising one or more  pairs  of coupled optical fibres, the or each pairs of coupled optical fibres being aligned by two, and only two, elongated elements having cylindrical outer surfaces. The two elements have their axis parallel and their two cylindrical surfaces in contact along their lengths to define an elongated bicuspid interstice, the pair of coupled optical fibres having their end portions disposed in and ex-tending in opposite directions along their interstice, each optical fibre end portion being in contact with both cylindrical surfaces.  The fibres are located and aligned by the two adjacent cylindrical surface only, that is to say without any assistance from the third cylindrical surface, thereby avoiding the disadvantage that the fibres must all contact the three surfaces, which requires very close dimensional tolerances.

Abstract: ABSTRACT OF THE DISCLOSURE    Mixture ratio control for internal combustion engines supplies a constant current into an exhaust gas sensor to develop a voltage of a substantial magnitude in proportion to the initial high value of the gas sensor internal impedance during low temperature conditions. The voltage so developed decreases as a function of time corresponding to the decrease of the internal impedance With temperature.          A voltage detector is provided to trigger the control system to operate in a closed loop mode when the gas sensor voltage is reduced to a level below a first threshold level.  Respon-sive to the output of the voltage detector the supplied current is momentarily interrupted to allow the gas sensor voltage to drop rapidly to a level which is higher or lower than a second threshold level depending on the concentration of the sensed gas in the exhaust system.  A second detector senses this voltage drop relative to the second threshold to determine whether the gas sensor output represents rich or lean condition.  The reference point of the closed loop is raised or lowered in response to the output of the second detector and further decreased as a function of time such that the reference point lies within the range between maximum and minimum peak values of the gas sensor output signal.

Abstract: ABSTRACT           A tilting nozzle closure for a bottle comprises a cap of plastics material having a side wall which has a low elastic deformability carrying an internal annular bead adjacent its open end for engagement with the neck of the bottle, at least part of the end wall of the cap being more resilient than the side wall and carrying a tubular nozzle and a closure member for sealing the neck of the bottle which, in use, engages with the end of the neck of the bottle and which includes a reduced portion which in use projects into the neck of the bottle.  The closure is arranged such that in use the at least part of the end wall is stressed by the attachment of thecap to the neck of the bottle to urge the closure member against the neck of the bottle to seal the bottle, but the closure member is movable from sealing engagement with the bottle neck to thereby allow the contents of the bottle to be discharged through the nozzle by the application of a transverse force to the nozzle to tilt it which results in the closure member being unseated from the neck of the bottle and in the at least part of the end wall being deformed.  In one example the closure member is integral with the cap and in another example the closure member is separate from the cap.
