摘要： A machine for the finishing of metal pieces which consists of a number of rectilineal cradle shaped vibrating units quipped with slides or casters or wheels to enable the units to move along two or more parallel metal guides or rails which constitute the work run of the machine; of two or more translating conveyor belts which move transversally to the movement of the vibrating units along the work run and which move the units from one guide to the other at the end of each work run; of a charging station for the pieces to be processed, placed at the start of the work run; of a discharge station for the contents of the units, placed at the end of the work run; of one or more work stations used for the processing of the pieces contained in the units and situated along the work run and of adjustable controls for the progress of the abovementioned units along the aforementioned guides.

摘要： The invention relates to the pretreatment of ductile non-ferrous metal to be deformed in a continuous plastic deforming device (20) in which the surface parts of the metal to be deformed do not substantially form surface parts of the metal after said deformation. Known methods of pretreatment include scaling off of thin surface layers and pickling e.g. in baths and coiling or storing the metal thereafter before feeding to the deforming device. Such methods have disadvantages in view of energy, waste of material and, in many cases, in still having some surface contamination on the metal entering the deforming device. To avoid such disadvantages, the invention proposes to spray the metal with a deoxidation and cleaning agent in one throughgoing operation directly while it is moving to the deforming device and continuously and synchronously therewith. Spraying is done by directing forceful jets of the liquid onto the moving metal surface. The spraying agent is a strong alkali and for some types of alloys there is a further spraying step using an acid such as a strong nitric acid solution in water. The metal is thereupon, while moving on to the deforming device, rinsed with water and dried.

摘要： A cleaning and anti-corrosion treatment for articles such as engineering parts and particularly for motor vehicles includes the following steps:-
(a) placing the vehicle in a chamber; (b) closing the chamber; (c) supplying a cleaning liquid containing a fat emulsifier to the chamber under pressure for a predetermined time; (d) washing the vehicle with water; (e) supplying a rust-removing and anti-corrosive liquid to the chamber under pressure for a predetermined time, and (f) drying the vehicle as necessary and removing it from the chamber. The anti-corrosive liquid used may be water-based and have the following composition per 100 ml of water:-
Citric acid (anhydrous) 3 to 52 grammes Fat emulsifier 0.001 to 4 grammes Corrosion inhibitor 0.001 to 3 grammes.
