Anyone read german? Short one page translation help needed

Hello, been looking at some older papers in chemistry, specifically dichromate oxidations and came across a paper in german which I can't get a good translation for.
The main question is what are the yeilds stated at the end? 80% or 8 of ten? Is someone would feel like typing up a short english version, much obliged.
This is a patent dealing w/ oxidation of codeine to 14hydroxycodeinone
---
20 Teile Kodein werden in 80 Teilen Wasser unter Zusatz von 25 Teilen Eisessig in Losung gerbracht und die
abgekuhlte Flussigkeit mit einer Losung Von 20 Teilen Natriumbichromat in 25 Teilen Wasser versetzt. Es
entsteht ein oliger Niederschlag, der nach kurzem Erwarmen fest und kristallinisch wird. Das Reaktionsgemisch
wird auf dem Wasserbade langsam unter standigem Ruhren auf 80 erwamt, wobei sich der Niederschlag auflost
Nunmerhr unterbricht man das Erwamen; infolge einer Nachreaktion steigt dic Temperatur bis etwa 90.
Nach kuzem Stehen kuhlt man stark ab un fallt die neugebildete Base durch Zusatz von uberschussiger
Chromsaurelosung als Bichromat. Die aus dem Bichromat in ublicher Weise isolierte Base kristallisiert aus Alkohol
in Blattchen vom Zersetzungspuknt 273 und zeigt die eigenschaften des von freund und Speye r beschriebenen
Oxykodeinons
Teile Kodeinon werden in 80 wasser unter Zusatz von 25 teilen eisessig in Losung gebracht und dann eine Losung
von 8 Teilen Natriumbichromat in 25 teilen wasser hinzugegeben. Der weitere verlauf der Reaktion gestaltet sich,
wie in Beispiel 1 angegeben. Man erhalt eine Ausheute von 8 bis 10 Teilen Oxykodeinon.
===
The lat section is particulary intersting. Man erhalt eine Ausheute von 8 bis 10 Teilen Oxykodeinon. What is that?

freetranslation.com gives me:
20 Parts code become water in 80 parts under addition of 25 parts ice vinegar in Losung gerbracht and that
Abgekuhlte Flussigkeit with a Losung of 20 parts Natriumbichromat in 25 parts water transfers. It
An oliger precipitation, that emerges heated after short firmly and kristallinisch becomes. The reaction mixture
becomes on the water baths slow under standigem Ruhren on 80 erwamt whereby the precipitation listed itself
One interrupts Nunmerhr the Erwamen; as a result of an after reaction, dic temperature climbs until about 90.
After kuzem standing kuhlt one strongly from un the newly formed base falls through addition of uberschussiger
Chromsaurelosung as a Bichromat. The base isolated out of the Bichromat in ublicher manner crystallizes out of alcohol
in leaf of the Zersetzungspuknt 273 and shows the characteristics the of friend and Speye r of described
Oxykodeinons
Kodeinon would divide will divide brought ice vinegar in Losung in 80 waters under addition of 25 and then a Losung
Of 8 parts Natriumbichromat in 25 divide water there supplement. The further course of the reaction forms itself
How in example 1 indicated. One receipt an Ausheute of 8 to 10 parts Oxykodeinon.
-----------
maybe that will help.

sorry too tired to translate the whole thing and i doubt i'm the only one here that speaks german anyway.
the last line means: one receives a yield of 8-10 parts oxycodeine.

20 parts Kodein are put in 80 parts Water with 25 parts icevinegar
and the cooled off liquid is transferred to a solution of 20 parts natriumbichromat(not sure what this chemical is, wasnt old enough to do science when i was in germany) in 25 parts water
an oily downforce occurs, that after a quick heating turns hard and crystaline Das Reaktionsgemisch
the reactionmix is heated under constant stirring to 80, which causes the downforce to disappear
now one stops the heating and the after-reaction brings the temperature up to about 90
After a quick stand, one cools down strongly and "fallt"(this could be fällt i guess but that doesnt make sense, its the important verb f the sentence tho) the newly created base through addition of leftover
Chromsaurelosung(copper acid solution?) as Bichromat. the out of the Bichromat standard isolate base crystalises out of alcohol
in leaves from Zersetzungspuknt(melting point i believe) 273 and shows the properties that are described by friend and speye r
Oxykodeinons
Parts Kodeinon are brought into solution in 80 parts water under addition of 25 parts icevinegar
and then given into a solution of 8 parts Natriumbichromat in 25 parts water. the rest of the reaction continues as described in example 1.
phew. sorry i dont know any technical terms or chemical names in german
