When coffee beans are contacted directly they may have a moisture content of 20-60% and contacting is at 30-150‹C. The fatty material should contain an equilibrium moisture content, e.g. 0.9-1.2%. Contacting may be performed in a multistage counter-current process. The fatty material may be sunflower, soy bean, corn, peanut or coffee oil, triolein or lard.

Abstract: Method and apparatus for heating by means of heat pumping. The heat pumping is effected in two separate pump stages (15-22-23, 16-24-25; 115-122-123, 116-124-125). In order to reduce the energy losses air is being circulated through a heat-insulated space (10; 110) which has a substantially adiabatic relationship to the surroundings thereof and includes the condenser (23; 123) of the first stage (15-22-23; 115-122-123) and the evaporator (24; 124) of the second stage (16-24-25; 116-124-125) and the compressors (15, 16; 115, 116) and drive machinery (12, 13, 14; 112, 113, 114) of the two stages. Heat absorbed by the air from the condenser of the first stage, the compressors and the drive machinery is supplied to the evaporator of the second stage. The pump stages have different pressure and temperature gradients and are thermodynamically dimensioned in such a way that the total of the heat absorbed equals the heat of vaporization of the second stage.

Date May 1, 1980.The invention relates to a method for regulating the phase position of a controlled signal in relation to the phase position of a reference signal in a telecommunication system, and an arrangement for carrying out the method. A reference signal (C2) is delayed in a delay circuit (DL1) and the delayed reference signal (C2) is delayed in a delay circuit (DL1) and the delayed reference signal (D1) is compared with a controlled signal (C1) in a first comparison circuit (FF1) which produces a first comparison signal (Q1) at a high or a low level in dependence on the phase difference between the delayed reference signal (D1) and the controlled signal (C1). The controlled signal (C1) is delayed in a delay circuit (DL2) and the delayed controlled signal (D2) is compared in a second comparison circuit (FF2) with the reference signal (C2). The second comparison circuit (FF2) produces a second comparison signal (Q2) which is at a high or a low level in dependence on the phase difference between the signal (D2) and the reference signal (C2). The outputs from the comparison circuits (FF1,FF2) are connected to a logic circuit (LC). In dependence on the signal combination received at its inputs the logic circuit produces a binary control signal which is used to correct the phase position of the controlled signal (C1) in relation to the phase position of the reference signal (C2).
