Abstract: The invention provides a method for moulding three-dimensional products from a mass of foodstuff starting materials which are suitable for consumption, in particular a meat mass. The method comprises the steps of filling a mould cavity, which is open on one side, with the mass of foodstuff starting materials which are suitable for consumption, which mould cavity is defined by a boundary comprising walls and base, in order to mould a moulded three-dimensional product, and the removal of the moulded three-dimensional product from the mould cavity. In the method according to the invention, during removal the adhesion forces between the moulded product and the boundary are eliminated virtually simultaneously along all the interfaces.

Abstract: A fully integratable bridge amplifier comprises two identical amplifiers (1; 5) each being provided with a first input stage (20; 40) whose inputs constitute the first non-inverting inputs (2; 6) and the first inverting inputs (3; 7) of the amplifier, a second input stage (29; 50) whose inputs constitute the second non-inverting inputs (28; 49) and the second inverting inputs (27; 48) of the amplifier, and an output stage (25; 45). The first inverting input (3; 7) of each amplifier (1; 5) is connected to the output (12) of a buffer amplifier (9) via a first resistor (R.sub.6 ; R.sub.9) which together with a second resistor (R.sub.5 ; R.sub.8) constitutes a negative feedback network between the output (4; 8) of the amplifier (1; 5) and the first inverting input (3; 7). The first non-inverting input (2; 6) is also connected to the output (12) of the buffer amplifier (9). This output (12) and consequently the first inputs (2, 3; 6, 7) of the amplifiers (1; 5) are at half the supply voltage with respect to the d.

Abstract: In an output amplifier (20) which is operated in class AB with the aid of quiescent-current means (40, 50) and which comprises first output-transistor configuration (T.sub.10 -T.sub.14) and a second output-transistor configuration (T.sub.15 -T.sub.17) with output transistors (T.sub.14, T.sub.17) of the same conductivity type, the drive signals for these output-transistor configurations are derived from the output signal (V.sub.i) of the input amplifier (10) by means of a single voltage-to-current converter (30). In the case of a positive drive of the first output transistor configuration (T.sub.10 -T.sub.14) this converter (30), together with the first output-transistor configuration (T.sub.10 -T.sub.14) and a load (R.sub.L) connected to the output (5) of the output amplifier (20), constitutes an amplifier configuration with full negative feedback, while in the case of a positive drive of the second output transistor configuration (T.sub.15 -T.sub.

Abstract: An amplifier arrangement for use in power protection circuits comprises two transistors arranged as a current mirror. The signal voltage is applied to the emitter electrode of one of the two transistors and the collector of the other transistor provides an output voltage via a resistor. The input circuit of the current mirror, in which the one transistor is included, is driven by a current source. Via an emitter-follower transistor the current source is coupled to the common base electrodes of the two transistors. The collector current of said emitter-follower transistor is fed to a tapping on said resistor in order to compensate for variations in the current gain factor of the transistors.

Abstract: A detector suitable for use in a recording amplifier of a cassette recorder for limiting the signal which is applied to the write head at a specific average amplitude. The detector comprises a pre-amplifier T1 to T4 having an input (15) and an output (17); a comparator (T6) having a first input (base) coupled to the output of the pre-amplifier, and a second input (emitter) for detecting whether a detection voltage at the second input is exceeded by the voltage on the first input of the comparator circuit; a reference voltage source (V.sub.ref); first means (4) for maintaining the d.c. level at the output of the pre-amplifier (T1 to T4) at the level of the reference voltage source (V.sub.ref); and second means (T10, T11) for raising the detection level of the comparator circuit by the reference voltage.
