Un émulateur (22) de télécommande du décodeur du câble est connecté en (23), entre le magnétoscope (14) et le décodeur (12) du câble. Tous les codes de sélection de canaux transmis au magnétoscope (14) par sa télécommande (20), sont transformés par l'émulateur (22) de télécommande en des codes d'instructions reconnus par le décodeur (12) du câble. L'émulateur (22) de télécommande supprime également l'exécution des codes de sélection de canaux transmis au magnétoscope (14), afin de maintenir le magnétoscope (14) syntonisé sur le canal fixe, dans lequel le signal du câble décodé est transmis. L'émulateur (22) de télécommande excite un émetteur infra-rouge, lequel est positionné devant une entrée infra-rouge se trouvant dans le décodeur (12) du câble. Ainsi, l'émulateur (22) de télécommande remplace la télécommande du décodeur de câble classique. L'utilisateur communique avec le système à l'aide de la télécommande (20) du magnétoscope. Pour l'utilisateur, le système (10) semble fonctionner comme le magnétoscope (14) connecté au téléviseur (19), sans décodeur (12) de câble.

Abstract: 2.1 From an amplifier and an integrating capacitor followed by comparators, an integrator with comparator outputs can be formed. The usable input voltage range for the comparators, however, is normally 2 to 3 V less than the operating voltage. A corresponding integrated circuit having this function would need a relatively large chip area. 
<??>2.2 The usable input voltage range for the comparators can nearly reach the magnitude of the operating voltage and the circuit can be accommodated on a reduced chip area by using transistors operated in saturation and a special circuit technique.

Title: Hydro-energy
Inventor: ANGER HEINZ
IPC: F01B21/02
Filed: 1991-11-14
Abstract: A new type of hydraulic system which, in continuous revolutions, with hydraulic intensification, converts forces from basic drives into high take-off forces. The magnitude of force take-off is here dependent on the size of the annular cylinder with the pressure surfaces which can be installed, the number of hydraulic cylinders in the annulus and the differences in surface area of the pressure-producing pistons. Annular cylinders with transmission multiplication capacity can furthermore be attached to one another (in the form of an assembly), the transmission ratio being multiplied according to the number. Transmission ratios, input force to take-off force, of from one to ten to one to one thousand and greater are possible here (Figure 1). In this system, there are no pressure-producing pumps. The way in which the system is constructed can vary greatly. It can be constructed as a stationary system or connected downstream of existing engines, steam engines, hydraulic motors, wind machines or turbines. This system can with great advantage be fully integrated into new systems comprising the abovementioned machines. As a further possible application, in vehicles, this system can be installed directly in the driving wheels (Figure 4). The system operates as follows: the annular cylinder is mounted on rolling bearings on the driving shaft which supports the external drive. The shaft torque is transmitted by annular thrust segments or toggle-lever systems to the pistons, which press into the hydraulic fluid. The pistons have two different diameters and a particular function for each diameter. They lead into hydraulic cylinders. Installed in the annular cylinder are pressure surfaces, cross-webs, toggle-lever systems and the pressure-multiplying hydraulic cylinders with pistons. The annular cylinder is filled with hydraulic fluid and screwed shut in an oil-tight manner. The hydraulic multiplication is due to the difference in the surface area between the small piston surfaces and the pressure surfaces and the cross-webs. In addition the hydraulic fluid also presses on the large piston surfaces, which, on the one hand, multiply pressure and, on the other hand, transmit the multiplied force to the small piston and have a pressure-intensifying effect. System dimensions: the diameters of the annular cylinders can be between 150 mm and 5 m and even larger if technically possible. The diameter is specified as desired depending on the energy requirement. <IMAGE>
