21. The transmission system has four forward and two reverse gears, and incorporates the steering system and the hydraulic retarder . 22. In the 1960s the hydrodynamic retarder was also introduced as a third stage which complemented the torque-converter and fluid coupling. 23. It has developed various subsystems of transmission like torque converter, Fluid coupling and retarder , Steering units, Final drives etc. 24. A vapor-retarder , Lea explained, is the paper, foil or plastic found on " faced " insulation. 25. They claim that approximately 300 vehicles, mostly route buses are using Hinos HIMR ( Hybrid Inverter Controlled Motor & Retarder ) system. 26. This element consists of a second synchronously rotating quarter-wave retarder and a linear polarizer in front of the photo-detector. 27. When a vapor-retarder is used, he said, the vapor-retarder should be between the insulation and the area being insulated. 28. When a vapor-retarder is used, he said, the vapor-retarder should be between the insulation and the area being insulated. 29. Motive power for the Fuchs 1 is provided by a Mercedes-Benz Model OM 402A fully automatic six-speed transmission with integrated retarder . 30. A " "'dough retarder " "'is a refrigerator used to control the fermentation of yeast when proofing dough.
