A process for the preparation of a pressure-deformable resin which comprises the following steps: Preparation of 40% of a silicone rubber and 58% of a silicon oxide; introduction of the silicone rubber and the silicon oxide into a stirrer (stirring unit); melting of the mixture and thorough stirring of the mixture for 20 minutes in order to mix the mixture uniformly; addition of 1% of pigment to t...

A process is proposed for separating volatile aroma substances from liquid mixtures, and an apparatus for carrying out such a process which additionally includes a separator. In the process, the liquid mixture is separated by a separation membrane into a retentate and a permeate containing the aroma substance in enriched form.

A granular vinyl chloride polymer is produced by mixing an aqueous dispersion of a vinyl chloride polymer with an organic liquid being difficulty soluble in water and incapable of dissolving or swelling the vinyl chloride polymer to prepare an aggregate of particles of the vinyl chloride polymer, dehydrating the aggregate and then drying it. The drying is carried out by using a fluidized drying ma...

Electrodepositable primer compositions comprising an aqueous dispersion of an ionic epoxy-based resin, a hindered amine light stabilizer and an antioxidant mixture which comprises a phenolic antioxidant and a sulfur-containing antioxidant. The primer compositions find particular use under topcoats which are permeable to UV radiation which, in the absence of the hindered amine and antioxidant mixtu...

A trimming process by a laser beam is disclosed. The trimming process comprises two steps. In a first step, a laser shield layer (12) is formed over an untrimmed region (11a) of a trimmed material (11) adjacent to a trimmed region (11c). The laser shield layer has a higher heat conductivity than the trimmed material and a large reflectivity for laser beam. In a second step, the trimmed material is...
