    摘要: Epoxy acrylates and carboxyl group-containing epoxy acrylates of formulae III and IV of the claims that are relatively polymolecular and are chemically crosslinkable can be used in photoresist formulations with the additional use of highly polymerized polymer binders. Such resist formulations are used in particular in the field of printed circuit boards and printing plates, are applicable from aqueous medium, are almost tack-free and have very good edge coverage, especially on conductors.

    摘要: A coaxial valve includes an actuating drive, a valve housing (11), a valve sleeve (12) that is longitudinally slidable in the valve housing (11) between open and closed positions, and a closing body (13) arranged coaxially at one end of the valve sleeve (12). In the closed position, the valve sleeve seals against the closing body. In the open position, the valve sleeve is spaced from the closing body, to open a valve opening cross-section (V). The actuating drive includes an electric servomotor (21) with a linear actuator (22), and a transmission mechanism (30) for transmitting the linear movement of the actuator to the valve sleeve. The transmission mechanism includes a rocker lever with a first end articulately connected to the linear actuator, a second end articulately connected to the valve housing, and a middle section articulately connected to the valve sleeve.

    摘要: Orthocarbonates of the formula I ##STR1## in which R is C.sub.1 -C.sub.4 alkyl, x is zero, 1 or 2, and A is a trivalent radical derived from an aliphatic triol by omitting the hydroxyl groups, the hydroxyl groups of the triol being bonded to different carbon atoms, are suitable as cocomponents in the curing of epoxy resins in that they limit the reduction in volume occurring during curing of epoxy resins. In addition, the cured resins are distinguished by increased flexural strength and impact strength.
