The angle adapter according to the invention for a powder spray device comprises an upstream housing, which has an upstream powder channel, a connection to the powder spray device, and a longitudinal axis, about which the housing can be rotated. The powder spray device additionally comprises a pivot body comprising a downstream powder channel, which connects to the upstream powder channel The pivot body can be pivoted about a pivot axis, whereby the pivot axis runs obliquely to the longitudinal axis. A nozzle is additionally provided, which connects to the pivot body. Several webs and grooves are provided at the housing and pivot body, whereby the webs protrude into the grooves, and the webs and grooves are formed so that they form a labyrinth. A high voltage line is furthermore provided, which extends from the upstream housing via the pivot body all the way into the nozzle and which is formed there as high voltage electrode.

A cosmetic treatment method. The method includes creating, on a region of the keratin materials to be treated, a set of adhesive areas and of non-adhesive areas extending between the adhesive areas. The method includes electrostatically projecting fibres onto the region.

Techniques related to retroreflective surface layers for micro-mobility transit vehicles are disclosed. A retroreflective surface layer may be formed over at least a portion of a component of a micro-mobility transit vehicle by forming a powder coat layer over the portion of the component and baking the powder coat layer to cure the powder coat layer. An uncured clear coat layer may be formed over the powder coat layer. The uncured clear coat layer may be impregnated with a plurality of glass beads via an air-pressure applicator. The uncured clear coat layer impregnated with the glass beads may be baked to cure the clear coat layer. The retroreflective surface layer may include the powder coat layer, clear coat layer, and the plurality of glass beads distributed within the clear coat layer. The retroreflective surface layer may reflect incident light back to its source with minimal scattering of the light.

An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO.sub.2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO.sub.2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO.sub.2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO.sub.2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO.sub.2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.
