Abstract: The invention relates to a process for the preparation of resols by reacting phenolic compounds with aldehydes with catalysis by metal salts whose cation can easily be precipitated as low-solubility salts in industrial processes. In this process, a dispersant is added to the reaction mixture comprising phenolic compound, aldehyde and metal salt before, during or after the condensation reaction, and a complexing agent is admixed after the condensation reaction is complete and after the dispersant has been admixed. The resultant resins are transparent even after neutralization using sulphuric acid.

Title: Current supply circuit for roof support electrohydraulic control system or other control systems used in mining and underground building
IPC: H02J3/14
Filed: 1988-05-09
Abstract: A power supply arrangement which is intended, in particular, for intrinsically safe electro-hydraulic control systems for mining and comparable applications, in which several control units and loads controlled thereby are supplied as a group from a common constant voltage source. The voltage source has a current capacity which is smaller than the total current requirement of all the units and loads supplied by it. Each control unit has actual value current measuring device and two controllable current sources which are connected to a common potential line which can simultanously act as a data bus. The arrangement enables the respective effective dynamic current consumption and demands of the control units and loads to be ascertained to enable the available power of the constant voltage source to be determined at any time at the individual control units. The available power of the source can be utilised for an optionally time-staggered ordered control process according to predetermined priorities without overloading the voltage source.
