Abstract: Oligoester acrylate resins having a high content of solids and comparatively low viscosity, and aqueous coating agents with a low content of organic solvents for obtaining coatings with high resistance to chemicals, more particularly high resistance to acids and oily soot, and very low tendency to yellowing.

Abstract: The invention concerns a binder suitable for clear or pigmented coating agents. Binders based on copolymers containing hydroxyl groups have hitherto a high solvent content. The solids content of the new binders is improved without affecting the viscosity; gloss, body, flow and processing properties of coatings containing the new binders are improved. The binders consist essentially of a copolymer containing hydroxyl groups, made from specific quantities of styrol, tertbutacrylate, isobutyl methacrylate, 2-ethylhexyl methacrylate, 2-hydroxypropyl methacrylate, butanediol-1, 4-monoacrylate, acrylic acid and glycidyl esters of .alpha.-alkylalkane monocarboxylic acids and/or .alpha.,.alpha.-dialkylalkane monocarboxylic acids.

Abstract: A displacement pick-up arrangement for the position detection of a plunger is a component of a pressing station of a section of an I.S. glass-forming machine in which a plunger is inserted into a mold recess of a parison mold holding a glass gob at this time, and includes a ring-shaped core which is carried by a piston rod mounted to said plunger. The core forms an actuating element for changing the inductivity of a coil which is arranged in a ring-shaped frame between a cylinder and a guiding cylinder for the plunger.
