Patent DE-2012162-A1 (DE)
Title: Surface cleaning process whereby impuritiesa
IPC: C23G3/00
Filed: 1970-03-14
Abstract: Cleaning plant for the removal of impurities, partic. flux and soldering residues from printed circuit boards, employs a washing fluid which dissolves the impurities forming lyophobic colloids and which then passes into a chamber which is connected with a separating device, this being fitted with a cooling device used for the regeneration of the cleaning fluid. The fluid may e.g. be a mixture of (A) toluol, (B) acetic acid -n-butyl ester, (C) isopropyl alcohol, and (D) 1, 1, 2-trichlor- 1, 2, 2 trifluoroethane, where (A) + (B) >=15 vol.% of the sum of all the components. The fluid dissolves the colloids to a greater extent as its temp. is increased. The impurities are precipitated out by cooling when fluid is regenerated. An advantage of employing this process is that the impurities are converted into chemically inert colloids, thus even if they are not all washed off, they have become harmless.

Title: Multi-unit rotary gravure printing machine - central drive-motor to drive all units
Inventor: RAMBAUSEK HUGO DIPL-ING
IPC: B41F13/00
Filed: 1973-07-05
Abstract: Basically the system allows the driving parts of a printing press to be subjected to constant back pressure so that no variations will exist in the various units, which otherwise may create variations in the printed matter. To create this constant back pressure a slip coupling is provided in each of the sub power transfer circuits. This slip coupling has a predetermined, speed related capacity. This in turn has the effect that any backlash is always in a predetermined direction, and not as usual in both directions. The result is a better control of sheet and cylinder with a better register on each colour.
