Abstract: A nozzle for a spray gun, in particular a paint spray gun, has at least one material nozzle having a hollow portion for the passage of material to be sprayed; a material outlet opening; and a disk element extending radially from the material nozzle and having at least one passage opening. The nozzle has at least one first baffle disk which is arranged on the disk element and has an inner and an outer circumference. The first baffle disk is arranged on the disk element directly, in particular without a sealing element arranged inbetween. The disadvantages that separate sealing elements have to be specially produced and may be lost or damaged, can thereby be avoided. The nozzle according to the disclosure and related nozzle sets, paint spray guns and methods for producing nozzles are functionally reliable, have only few individual parts and a compact design and are quiet.

Abstract: A main body for a spray gun, in particular a paint spray gun, has at least one head region for attachment of a nozzle arrangement. The head region has at least one inner wall, one outer wall and one middle wall arranged therebetween. The walls are formed in encircling fashion and in one piece with the main body, with the front end of the middle wall set back in relation to the front end of the outer wall along an axis. This main body does not require any additional sealing element for sealing between the atomization air region and horn air region. The middle wall is well protected against damage even when a nozzle has been unscrewed, and the gun head can be of very compact design.

Abstract: In a load monitoring device of a mechanical type with a deformable basic body (1), the latter has a deformation part (2,3) provided with detent stops (5,6,7) which hold pivoting levers (10,11) in positions corresponding to different load ranges. When predetermined limit values are reached, the detent stops (5,6,7) release the free ends (8,9) of the pivoting levers (10,11), and these are transferred by springs (12) into positions corresponding to the respective degree of loading or of overloading.

Abstract: Fatty acid esters of oxalkylated alkylalkylenediamines, which may be quaternized:Esters of oxalkylated alkylalkylenediamines, which may be quaternized, of the formula ##STR1## where the individual symbols have the meaning given in the description, process for their production and their use as corrosion inhibitors, particularly in crude oil recovery plants and crude oil treatment plants.

Abstract: A process for providing gamma globulin with improved intravenous compatibility. In the process, gamma globulin precipitated from blood or blood products is dissolved in an aqueous solution containing a hydrocolloid. The hydrocolloid is capable of forming a lyophilic sol. Gamma globulin is then precipitated from the solution to provide gamma globulin having improved intravenous compatibility.
