Abstract: A method of controlling a lift installation with at least one lift car, at least one lift control and at least one mobile apparatus, and a control system for a controlling a lift installation. A reporting device near the lift installation receives at least one activation signal from a transmitting/receiving device of a mobile apparatus. The reporting device activates in response to the received activation signal. At least one network address of a recognition device of a lift control of the lift installation is transmitted from the activated reporting device to the transmitting/receiving device of the mobile apparatus.

Abstract: This invention relates to benzylic ether phenolic resole resins prepared in a sealed reaction vessel and their uses. The benzylic ether phenolic resole resins are prepared by heating phenol and an aldehyde in a sealed reaction vessel in the presence of a divalent metal catalyst without removing water generated by the reaction until an appropriate endpoint for the resin is reached. The benzylic ether phenolic resole resins produced by the process are preferably free or essentially free of unreacted formaldehyde and can be used in the resin component of phenolic-urethane foundry binders to make foundry cores and/or molds by the cold-box and no-bake processes. The cores and/or molds are used for making metal castings.
