Abstract: ABSTRACT OF THE DISCLOSURE        A vapour generator is disclosed having a vertical flue and a transverse flue branched off the former.  The tubes of the flue walls extend longitudinally of the respective flue. Some of the wall tubes of the vertical gas flue are used as support tubes whose top ends are secured to a support structure.  The tubes of the transverse flue are bent outwards of the respective wall planes at the point where the transverse flue branches off.  The non-supporting tubes of the vertical flue are bent outwardly so as to become disposed in groups, each group coinciding with a vertical plane generally parallel with the direction of and disposed within the transverse flue.  Each such plane also includes one of the supporting tubes, the supporting tubes being the only ones continuing within the plane of the upright wall of the vertical flue.  Near the top wall transverse flue, the non-supporting tubes of the vertical flue are again bent back to return to their original alignment with the corresponding wall of the vertical flue.  The points where the non-supporting tubes are bent away from and back to the vertical flue wall are disposed exteriorally of the transverse flue.  Structural simplicity of a vertical gas flue and a more uniform length of the tubes forming the vertical flue are among the features of advantage of the present invention over prior art.

Abstract: ABSTRACT OF THE DISCLOSURE The hollow tubular member or blank which is to serve as a sleeve for a corroded tube of the steam gener-ator of a nuclear reactor plant and which is too long to be manipulated under the tube sheet of the reactor,  is prebent into a shape such that it can be manipulated and is then progressively straightened under the tube sheet as it is progressively inserted into the tube.  The straight-ener includes a plurality of grooved rolls mounted stag-gered and rotatable in a train.  Each roll forms a channel engaging half of the periphery of the member.  The contour of the engaging surface of each roll is the same as the contour of the member over half of its peripheral surface so that each roll mates with the member over half of its peripheral surface.  The rolls are in frictional engagement with the member and advance the member while bending it so that the material of the member is stressed beyond its elastic limit oppositely to the stress beyond the elastic limit,  which  produced  the  bending,   sufficiently  to straighten the hollow member.

Abstract: ABSTRACT           A reference frequency and low voltage detector circuit for use with a constant frequency A.C. voltage source is disclosed in which a first supply circuit supplies a first voltage wave form having a repetition rate and magnitude proportional to the A.C. source voltage.  A second supply circuit supplies a regulated D.C. voltage of a fixed magnitude as long as the amplitude of the A.C. source voltage is normal.  The voltages produced by the first and second supply circuits are supplied to noninverting and inverting input terminals of a differential amplifier which produces a rectangular wave output signal only when the A.C. source voltage is normal.  The differential amplifier output signal provides a frequency reference under normal conditions and signals a user device to switch to a secondary mode of operation when the repetition rate of the rectangular wave form changes.

Abstract: ABSTRACT        PROCESS FOR THE ELECTROLYTIC PRODUCTION          OF FLUORINE AND NOVEL CELL THEREFOR      A cell and process is provided for the production of fluorine comprising electrolyzing a liquid mixture of fluorides of alkali metal, ammonium and hydrogen fluoride.  The cell anode comprises a  stack of anode plates with internal passages or it may comprise a carbon shape provided with grooves and passages and fitted to a central conductor which conducts current from the exterior of the cell to the carbon anode plates within the cell.  The anode having a substantially expanded working surface has the capability of removing fluorine internally.  A louvered cathode permits most of the hydrogen to be vented away from the zone between the electrodes through which current passes thus reducing the ohmic voltage loss.  The cathode, rather than being louvered, can be expanded metal or punched sheet or gauze.  The anode, cathode and barrier may be cylindrical in form although other shapes, for instance rectangular or square in cross section or even of hexagonal section, may be used if desired.  Combination of the segmented anode design with a louvered cathode provides a unique cell for fluorine production because virtually the same electrolysis condition exists at any part of the anode and cathode.

Abstract: CHIMNEY CLEANING APPARATUS Abstract A chimney cleaning system is permanently installed on a chimney for cleaning a flue of the chimney by either manual or automatic operation.  The flue brush is seated in the chimney flue with cables also inside the flue secured to both ends of the brush for pulling the brush either upward or downward.  A control box with a clutch mechanism for actuating or driving the cables in either direction by manual or automatic operation is installed outside the chimney at a convenient selected location on the side of the chimney.  First and second lengths of cable secured to the top and bottom of the flue brush pass around pulleys mounted or anchored at the top and bottom of the chimney, then pass through guide sleeves and holes drilled in the side of the chimney to the control box.  The control box is provided with a crank shaft and first and second reels mounted on the crank shaft for free wheeling on the shaft.  A clutch mechanism upon actuation engages the shaft with either the first or second reel for rotation of either the first or second reel with the shaft while the other reel remains free wheeling.  Thus, the reels can rotate in opposite directions on the same shaft reeling in one length of cable for pulling the brush in a desired direction while paying out the other length of cable on the slack side of the brush.  The crank shaft can be rotated by either a manual crank or a motor such as an electric hand drill.
