Title: Rebuilding of worn, wear resistant machine parts - is carried out by diffusion treatment such as nitriding, boronising, carburising or carbonitriding
Inventor: SCHEIBE WOLFGANG
IPC: C23C8/00
Filed: 1978-10-06
Abstract: The parts are esp. those requiring high dimensional accuracy and high wear resistance and, when they become worn, they are subjected to a diffusion treatment, e.g. nitriding, borom diffusion, carburising, or carbonitriding, in solid, liq. or gaseous media., so atoms diffuse into the parts and form cpds. with the substrate. The diffusion process results in the growth of the parts, and is controlled so that the parts are restored to their original dimensions. Used, e.g. for rebuilding pistons and cylinders of diesel fuel injection pumps.

Title: Formaldehyde treatment of liq. manure - giving deodorisation, disinfection and stabilisation
Inventor: LEGEIN KAREL LOUIS
IPC: C05F3/00
Filed: 1979-01-09
Abstract: Liq. manure is deodorised, disinfected and stabilised by treatment with a soln. of HCHO. The manure is from pig, poultry, beef or calf rearing. The amt. of HCHO used depends on the concn. of the soln. and the reactivity of the manure. Reaction of HCHO with the manure leads to foaming; the amt. of foaming is proportional to the viscosity of the manure, the rate of mixing of the HCHO and manure, the temp., the concn. of the HCHO soln., and possible local over-concn. of the HCHO in the manure. The treated manure can be stored for months in the open air, without affecting the adjacent environment. Bacterial action in the manure is stopped, the treated manure can be exposed to increased temp. or can be dried.
