An apparatus and a method for molding optical lenses are disclosed. The apparatus comprises a first molding shell with a first diameter, a sealing element surrounding the first molding shell, and means for radially clamping the sealing element against the first molding shell, a second molding shell having a second diameter greater than the first diameter, and means for axially clamping the second molding shell with its inner shell surface against a radial front surface of the sealing element. This is done such a hollow cavity is enclosed between the molding shells and the sealing element. The radially clamping means and the axial clamping means are structurally distinct and independent one from the other. The axially clamping means are arranged on an outer shell surface of the second molding shell, opposite to the inner shell surface.

A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50.degree. C. and 90.degree. C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

Apparatus for controlling the operation of the engine-transmission

To improve vehicle operator comfort and safety and to reduce wear and tear on the automatic transmission, the apparatus prevents an upshift whenever the accelerator pedal is released very quickly. The apparatus stores the load signal which prevailed when the load was abruptly reduced, thereby simulating to the transmission controller a continuation of high load and preventing an undesired upshift, for example in downhill operation and during roll-outs. Normal load signals are restored whenever the accelerator pedal is returned to a predetermined point. In one embodiment, the stored load signal is a hydraulic pressure and in another embodiment, for use with an electronic transmission controller, the load signal is an electrical signal. In a third embodiment, the upshift control signal from the controller to the transmission is interrupted when the apparatus indicates a complete release of the accelerator pedal.
