    Abstract: The invention concerns a device for the oil treatment of sintered parts consisting of a drum (11, 111) which is mounted so that it can rotate about a vertical axis and which can be driven. It has a drum mantle (11′, 111′) and loading and unloading devices so that it can be loaded and unloaded axially, a floor that tightly closes the opening in the floor (19, 119) against the-drum mantle (11′, 111′), connections (28, 29, 30, 31/128, 129, 130, 131) leading into the drum (11, 111) for liquid and gaseous treatment media for carrying out the treatment phases, and outlets (35, 135) for letting treatment fluids out of the drum (11, 111). The task of the invention is to create a device that not only mechanizes the treatment process but also can be repeated many times, always in the same way. This problem is solved by the connections (28, 29, 30, 31/128, 129, 130, 131) being arranged to lead axially into the loading opening and the outlets (35, 135) through the drum mantle (11′, 111′).

    Abstract: An epoxy resin composition is disclosed. The composition comprises a polyepoxide and a curing amount of a bis(hydrogen maleate) derivative of a polyoxypropylenediamine. This composition when cured produces unexpectedly superior encapsulations which are more flexible and less brittle than those of the prior art.

    Abstract: A self curing aqueous solution/dispersion comprising about 50-70 wt. % water, about 25-35 wt. % of a novel N-polymethylene substituted polyoxypropylene polyamine and about 3-9 wt. % of a curable polymer-forming component such as an epoxy-resin is described. The solution is useful for injection into permeable earth formations such as unconsolidated sands to reduce their permeability and consolidate the formation. Novel N-substituted polyamines of the formula [NaO.sub.3 S--R.sub.1 ].sub.m A wherein R.sub.1 is a C.sub.2 to C.sub.6 polymethylene group and A is a polyoxyalkylene polyamine are employed in the solution to render the epoxy-resin component adequately soluble or dispersible in the aqueous solution and to act as the curing agent for the resin.

    Abstract: The blade-type focal plane shutter formed with a plurality of telescopically operating opening blades movable in front of a film gate. A drive lever for the opening blades is operatively connected to said opening blades and carries a diffusedly reflecting mirror which before the commencement of the exposure operation lies in front of the opening blades in the film gate and is movable out of the film gate during the opening movement of the opening blades. The mirror together with the opening blades forms a reflection factor which corresponds to the mean reflection factor of different film types.
