Abstract: The invention relates to a process for the production of tall oil from soap oil and to the use of heating in order to improve the production of tall oil. Soap oil, which has been produced by neutralization of tall oil soap, is acidulated by reacting the soap oil with an acid and freed tall oil is recovered. In the acidulation step, the temperature is raised above 100° C., preferably over 105° C., for improving the acidulation of soap oil. The acid is preferably concentrated sulfuric acid.

Abstract: This device (12, 14) for mixing radiofrequency signals (RF) comprises: —a mixer circuit (18, 20) adapted to mix at least two signals, one of which is a radiofrequency signal; and —a current mirror circuit (22, 24) receiving signals delivered by the mixer circuit and delivering output signals. Wherein said current mirror circuit (18, 20) has two stages, each with a low pass passive filter.

Abstract: The invention concerns controlling automatic gain control for a digital signal receiver. The method includes receiving a digital feedback signal for controlling an amplifier and processing the digital feedback signal to deliver a driving signal to an analog amplifier. Processing the digital feedback signal comprises regulating the evolution of the driving signal so that it is maintained constant during a predetermined period of time after every change.

Abstract: There is a need for a cheaper method of producing bleached TMP and CTMP without impairing the properties of the pulp.

Abstract: A device for determining and adjusting the upper dead-center position in piston engines, in which the position of the piston is measured by an electrically operated sensor (1). The sensor (1) is an eddy-current sensor.

Abstract: A configuration arrangement, data processing system and a computer program product for flexible communication infrastructure for a multi-user application to be provided to a programmable application network. Each user is a client comprising a client computer and is able to participate in the application as a session participant. Human supervising commanding operator after installation of the configuration elements should be essentially avoided. At least one session profile comprises a set of application network parameters valid for an application session (APS). The session profile initializes and prepares the programmable application network in connection with or before the start of the application session. Each of a number of client profiles comprises a set of application network parameters valid for the client participating in an application session.

Abstract: A device for determining and adjusting the upper dead-centre position in piston engines, in which the position of the piston (5) is measured by means of an electrically operated sensor (1). The sensor (1) is an eddy-current sensor.

Abstract: A protective circuit is disclosed for protecting an integrated circuit against electrostatic discharge, so-called ESD. The integrated circuit is connected to a supply voltage via a V.sub.cc -pad (2) and an earth pad (3). The protective circuit, which is particularly intended to protect a positively supplied circuit for radio frequency applications against both negative and positive voltage pulses, comprises an input pad (14) and at least one PNP-transistor (20), the input pad being connected to the integrated circuit, and the PNP-transistor being connected with its collector to the input pad, and its emitter to the V.sub.cc -pad or to the earth pad. The base of the PNP-transistor can be connected to its emitter either directly or via a resistor (24), or not be connected.

Abstract: The present invention relates to a method for arrangement of a buried capacitor on a substrate or the like, and a buried capacitor arranged according to the method. In order to diminish the resistive losses in a capacitor and to make it more efficient, in semi-conductor circuits, instead of the polycrystalline layer, one or more bodies of metal such as aluminum or tungsten may be used. This has been made possible using a new technique in which a trench filling of conducting material is etched away without removal through etching of the insulating layer in the trench. After the removal through etching of the trench filling, the trench is filled using the metal as above, whereby the insulating layer between the conducting material and the metal body will separate two conducting surfaces, thereby forming the buried capacitor.
