The first control valve (20) has a first intake (24) via which a first intake flow from the first utility port (A) to the consumer (10) is controllable, has a first return control orifice (26) via which a first return flow (28) from the consumer (10) via the second utility port (B) is controllable simultaneously with the first intake (24), has a second intake (34) via which a second intake flow from the second utility port (B) to the consumer (10) is controllable, and having a second return control orifice (36), via which a second return flow (38) from the consumer (10) via the first utility port (A) is controllable simultaneously with the second intake (34). A second control valve (40) has an intake control orifice (42) used to control the respective intake (24, 34) of the first control valve (20).

Abstract: A control device, in particular for hydraulically controlling components of mobile working machines, has a pressure supply connection (P) and a tank or return connection (T) in addition to two user connections (A, B). Control and/or regulating valves (10, 14, 16, 18) are connected between the individual connections (P, T, A, B). Two control lines (C, Z) can control at least one of the control and/or regulating valves. A modular-type functional block (24, 26) is connected to at least one of the control lines (C, Z).

Abstract: Known electron beam lithography used for manufacturing male molds is cost-intensive and very time consuming. As a result, conventional highly sensitive electron beam resists have an insufficient plasma etching resistance and galvanic molding makes special demands on the structural profile and the thermal stability and solubility of the resist structures. The novel production and use of lithographically produced resist structures as male mold material for use in imprint lithography for producing microstructures and nanostructures should thus overcome the drawbacks associated with the conventional procedure for producing male molds. To this end, a negative resist system is used whose lithographically produced structures correspond to the demands made on a male mold for molding thin polymer layers. Lithographically produced structures comprised of curable materials are thus used for molding, preferably those based on photo-reactive epoxy resins.

Abstract: Process and system for programmed control of a home and building automation system, for saving energy and improving comfort, with the process being performed by means of software and presence and activity monitoring sensors. The software includes first adaptive algorithms controlled by signals from the presence and activity monitoring sensors, for continuously detecting and storing systematic and stochastic behavior of at least one person in a room and over several rooms, and including second modifiable deterministic algorithms for adapting and triggering actuators of installations or groups of installations. The algorithms are combined with external parameters into a third algorithm to optimize the automation system as a whole and to adjust the first and second algorithms by means of feedback.

Abstract: Crosslinked polymer layers having nonlinear optical properties are produced by a process in which (A) diallyl esters of aromatic dicarboxylic acids or mixtures thereof with monoallyl monoalkyl esters of aromatic dicarboxylic acids are copolymerized with compounds having nonlinear optical activities and containing groups capable of polymerization or (B) prepolymers of diallyl esters of aromatic dicarboxylic acids or prepolymers of mixtures of diallyl esters of aromatic dicarboxylic acids and monoallyl monoalkyl esters of aromatic dicarboxylic acids are mixed with compounds having nonlinear optical activity and with or without polymerizable groups (=guest/host system), applied to a substrate and, after orientation in an electric field above 50.degree. C., crosslinked in a reaction which is initiated thermally or by free radicals.

Abstract: Structured polymer layers having nonlinear optical properties are produced by a process wherein either organic compounds containing ethylenically unsaturated groups are subjected to free radical copolymerization (A) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, or organic compounds containing ethylenically unsaturated groups are subjected to free radical polymerization and are mixed (B) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, the copolymers (A) or mixtures (B) thus obtained are exposed imagewise to high-energy radiation, the unexposed parts are removed and the structured polymer layers thus obtained are polarized in an electric field for orientation of the chromophoric structural units in the region of the glass transition temperature of the polymer and crosslinked in an applied electric field.
