Methods, apparatus, and systems for inserting overlay content into a video signal are provided. An overlay content signal containing overlay content is received. In addition, a compressed video signal is received from a video source and decoded. An insertion window portion of the decoded video signal is identified. The overlay content signal and the insertion window portion of the decoded video signal are processed to produce a modified insertion window portion of the video signal. The video signal and the modified insertion window portion are then processed to produce a modified video signal. The data rate of the video signal may be modified during the overlay content insertion process.

A device for handling stacking or removing articles from a stack, has a stacking wheel located between the lifting elements for stacks and a conveyor. When the stacking wheel turns, depending on the direction of its rotation, an article is moved from the conveyor onto the stack in the lifting direction. The stacking wheel bears pairs of holding plates distributed around its periphery; on them swivelling fingers are supported. The swivelling fingers are pressed by springs into their action position in which they project over the facing surfaces of the holding plates and fit into receiving openings of the articles when articles are moved by the stacking wheel. Control plates are assigned to the stacking wheel and engage with their ramp edges the concave, downwardly pointing surface of the swivelling fingers to swivel them into their readiness position which does not project to the inside over the holding plates.

The invention is concerned with control of a continuously variable vehicle transmission. The transmission in question is to have a variator (10) which is coupled between a rotary transmission input (32) and a rotary transmission output (46), to provide continuous variation in a transmission dive ratio, via a launch device such as a clutch (62; 68). The variator and the launch device are constructed and arranged to exert a required torque, defined by an input signal. In accordance with the invention, the same control signal is used to control both the variator torque and the torque capacity of the launch device. In such an arrangement, vehicle launch (i.e. moving away from rest) can be controlled in a straightforward manner by progressively raising the relevant control signal, preferably a hydraulic pressure signal. Further independent claims are including for applying traction load to races (20, 22) of the variator and for a method setting torque of the launch device (62; 68) higher than torque of the variator (10).
