Patent DE-4435316-A1 (DE)
Inventor: HAGEDORN OLAF
IPC: B65D27/00
Filed: 1994-10-01
Abstract: The invention relates to envelopes (3) made from waste paper. To this end, the recycled envelopes (3) are folded from pieces of waste paper obtained directly from paper waste so that its preparation does not require the use of any chemical additives, e.g. bleaches, and the addition of water. According to the invention, the waste paper collected and sorted for this purpose is cut into the sections (1) to be processed further, whereby the section shapes (1) and the position of the fold lines (2, 4, 6, 8) are advantageously laid out according to the waste paper sizes used. As the waste paper requires no laborious processing, the production and use of the envelopes (3) of the invention for postal and other purposes results in a particularly favourable eco-balance.

Title: Linear amplifier circuit for direct current and alternating current
Inventor: RIEDER JOACHIM
IPC: H03F3/30
Filed: 1985-03-12
Abstract: The principles of "linear amplifier circuits for direct current and alternating current" have been known for a long time and are partly derived from the valve techniques. The type which is most commonly used at present comprises a differential input and a final push-pull stage and operates with a counter-coupling. The final transistors operate usually as emitter-followers at the dynamic operation point A-B. This principle requires that the voltage amplifier reaches the voltage amplitude of the output voltage. In the new "linear amplifier circuit for direct current and alternating current", the final transistors (T3, T4) operate as a common emitter at the dynamic operation point B-C and the currents thereof are coupled. The voltage amplitude of the voltage amplifier (OP) has no importance since said voltage allows only the flow of a current to zero. Said current, however, flows from the positive or negative side in the voltage amplifier (OP) and simultaneously controls the final transistors (T3, T4). In case of a small signal or without the latter, the output voltage (U-aus) is generated by two pretransistors (T1, T2). These also operate as a common emitter and their currents are also coupled. The output voltage is obtained from the difference of the collector currents of the push-pull transistors (T1, T2, T3, T4). Said voltage is counter-coupled to the differential input amplifier (OP) and is thus adjusted at a fixed ratio to the input voltage. As the voltage amplitude is smaller at the output (U-aus) of the voltage amplifier (OP) than the input voltage, its open loop amplifier is exclusively used to compensate for the non-linearities of the amplifier. Even the output load has no influence on the output voltage. As the voltage amplitude of the voltage amplifier is only a few volts, the voltage amplifier may be a conventional operational amplifier which is commercially available, even in the case where the output voltage of the final stage is high. Due to the dynamic operation point B-C of the final transistors (T3, T4), the ratio between the output power and the dissipated power is very advantageous, of the order of 3/1. This new principle enables the construction of better linear amplifiers with a reduced number of component parts.
