Abstract: ABSTRACT:           In a method of manufacturing a colour cathode-ray tube comprising a magnetic quadrupole post-focusing mask the mask is formed by a plate of permanent magnetiz-able material in which apertures are provided arranged according to rows.  Sections of the plate are success-ively magnetized by positioning parallel conductors on at least one side of the plate in such manner that each time two conductors through which an electric current flows in opposite directions are situated between two rows of aper-tures and a magnetic quadrupole is formed along the cir-cumference of each of the apertures.  A number of outer-most conductors determines an edge area of the section. In order to prevent the occurrence of disturbing magnetiz-ation errors in the edge area, the edge area is made to coincide with a part of a preceding section already magne-tized according to the desired strength.  A magnetic induction is generated in the edge area according to a pattern corresponding to the existing pattern in the pre-ceding section but having a strength which decreases towards the outermost conductor.

Abstract: OPTICAL AMPLIFIERS               Abstract of the Disclosure Use is made of stimulated Raman emission to induce gain in an optical signal (13) of a first wavelength.  The optical signal (13) and a pump signal (14) are synchronously coupled to a length of optical fibre (15).  The pump signal is at a second wavelength.          The first wavelength corresponds to one Stokes shift from the pump signal.  The pump signal is generated by a semiconductor laser (11) and thus only relatively low pump powers are involved in comparison with the conventional use of YAG lasers as the pumps, however significant gain is achieved despite the low pump powers.          Preferably the optical fibre (15) has a high Raman cross-section and a low transmission loss, for example GeO2 doped SiO2 or pure GeO2.

Abstract: ABSTRACT OF THE DISCLOSURE     This is a process of fabricating turbine blades for combustion turbines.  It is an improvement to the type of process where a mold containing molten metal is cooled in a controlled fashion such that  solidification occurs slow enough to allow single crystal growth beginning at the airfoil end.  In the  improved process  solidification is monitored and magnetic mixing of the remaining molten metal is started at approximately the beginning of solidification of said root section and at approximately the same time the rate of cooling of said blade is increased to a rate faster than at which single crystal growth occurs.  Grain boundary strengthener (preferably carbon) can be added at approxi-mately the same time mixing is begun.  A blade is produced with a single crystal airfoil section and a fine grained root  section  and  without  a  substantially  inhomogeneous portion at the  interface between  the  airfoil  and  root sections.

Abstract: Title ROTOR ANTI-REVERSE ROTATION ARRANGEMENT IN A SCREW COMPRESSOR                            Inventor James C. Tischer Abstract A body located downstream of the compressor discharge port in an oil-injected screw compressor assembly includes a contoured surface for directing the flow of the gas-oil mixture discharged from the com-pressor.  The body is movable in the compressor assembly between a first position in which the flow of the mixture out of the discharge port is unimpeded and a second position in which the backflow of gas from downstream of the discharge port back into and through the working chamber of the compressor is prevented.  In the first position the body facilitates the separation of oil from the discharged compressed gas while in the second position the reverse direction rotation of the screw rotors in the compressor working chamber is prevented.  The body is positionable to the first position under the impetus of the mixture discharged from the compressor and is positionable to the second posi-tion under the impetus of the initial backflow of gas from downstream of the compressor, back to the compressor, which occurs upon compressor shutdown.
