             Zo augustus ’99 voor de oppervlakte verbinding (55 m.) beide helmen twee haspels gemaakt.   Begin september ’01 kon weer eens een duik gemaakt worden. Moest er weer even inkomen.

           De bovenglas opzet nog even verbeteren.                                                                                           Begin oktober nog eens, ging flink beter die keer.

        Eind oktober een extra mogelijkheid klaar.     In september detail foto’s binnenwerk helm genomen.

        Nu is rebreath te duiken bij spoelen helm met lucht van oppervlakte.

                                                                                           Deze techniek zó werkte goed en betrouwbaar.  Te veel koppelingen en zichtbare leidingen, oogt niet.

                                                                           Alleen de beide reduceren waren door lichte vervorming, door later aan lassen, niet meer zoals ze

                                                                           wezen moesten. Door druk invloed nu loopt de dosering op.  Dat was weer te compenseren door dosering

                                                                           op diepte dan terug te zetten. Beide reduceren 4 instellingen en samen flink méér. Niet de bedoeling zó.

         De twee middelste zijn drieweg snel afsluitertjes. Ermee zijn beide 5 liter                                  Onder aan contralong in epoxy behuizing een afsluiter ter verwijderen water uit de long.

       cilinders bij te zetten op apart. De in V-vorm voor beluchten en ontluchten

       bovenste cilindertje klephuizen achter op helm.

                                                                                                                                                                                                        In P.V.C. huis een gesloten lood accu van 12 volt 6,5 amph.

                                                                                                                                                                       In behuizing aan met aan Lp slang, daar door stroomdraad, een

                                                                                                                                                                       zekering. Omgeving druk kan niet bij de accu komen.

   Tussen de twee grote klephuizen nu goed de ruisdemper spoellucht geplaatst met in actieve kool, flink                                De Lp en Hp slangen prima aangesloten zó.

   rustiger nu in de helm. Die harmonica slang zó later weer verandert.  Batterij geheel kan ook zó met op

   cilinders dan een simpelere absorptiepatroon opzet. Zó dan rebreath duiken bij helm spoelen met lucht

   van boven. Dat dan bij een langdurig karweitje, groot deels ter plaatse, op diep water. Moet even

   verder gegaan worden dan kan de oppervlakte verbinding los gekoppeld worden.

                                                                                                      73

                                                                                                            Even beide systemen in november ’02 achter huis op getuigt na wat aanpassingen.

 

                                                                                         27                                                                                                                               28                                            

                                    75                                       76

                                                                 De lamp goed af te stellen zo.                                                           Het bijtstuk ligt nu zonder hinder goed voor in de helm.

                    77                   78                      79

                                                                                                          Het solide binnenwerk grote kleppengeheel.

 

                                                               32                                                                                                                                                           33

                                                                                                                                                           De techniek voor spoellucht. Tussen afsluiters en begin en begin luchtslang. In de grote drietrap

                                                                                                                                  reduceer twee paddenstoel met een steel diameter van 11 millimeter. Het doseersysteem links

                                                                                                                                  boven heeft 8 snel instellingen. Nog geen probleem met die opzet zó gehad.

 

                                                                           34                                                                                                                                                                          35

     82-reduceers-onder      83

                      De tweetrap reduceren prima onder zo en kan bij afsluiters komen.

 

                                                                                           36                                                                                                                                                                            37

                                                                                                                                                        Even terug in de tijd, begin september ’01 een nieuw voorglas geplaatst en volledige revisie helm.

                                                                                                                                                        Die revisie benam nogal tijd.  Dat probleem loste ik op in ’05.

 

                                                                                                       38                                                                                                                                              39

                                                      87                                                     88

                                               Via deze opzet waren de doseringen op diepten goed te                                                       Een heel solide test tankje.

                                                        controleren. Zó goed duiken naar diepwater goed kunnen

                                               simuleren.
