Abstract: Abstract In a television receiver, a contrast control signal for controlling the amplitude of a video signal is a function of a manual contrast control component provided by a viewer, and an automatic contrast control component provided by a light sensitive circuit responsive to ambient light conditions.  A "soft" limiter limits the value of the control signal to prevent a displayed image from being extinguished due to excessive video signal attenuation in response to the control signal.  The manual control component is provided by means including a duty cycle control device such as a binary rate multiplier or pulse width modulator.

Abstract: Opening arrangements for packing containers often consist of a pouring opening formed in the packing container wall which is covered by a tear-off cover strip. To faciliate the removal of the cover strip, the same is placed so that it projects with one end portion outside the edge line of the container wall. However, this also increases the risk of unintentional opening. To reduce this risk the projecting end part (6) of the cover strip (5) may be folded about 180 DEG  to lie against the main part of the cover strip, at the same time as the cover strip is provided with one or more moulded portions (9) which make it possible to insert a finger underneath the grip lug (6) and lift the same when the cover strip (5) is to be removed.
