Patent EP-0049021-A2 (EP)
Inventor: BUHSE ULF
IPC: H04N5/60
Filed: 1981-09-28
Abstract: The invention relates to a circuit for use in a receiver which can receive two-tone/stereo signals. This circuit is intended to make a choice between mono or stereo reproduction of signal A or of signal B and vice versa. The circuit comprises two bistable multivibrator circuits which are controlled by a common, user-operable switch and by characteristic signals which are derived from the characteristic frequencies relevant to the different types of programs. The control is such that when the switch is operated only one bistable multivibrator circuit can be changed over (namely the bistable multivibrator circuit associated with the relevant characteristic frequency received.) A logic circuit which is controlled by the bistable multivibrator circuit as well as by the characteristic signals operates a change-over switch for switching to the desired reproduction.

Abstract: An operator for rotating blade dampers including a frame and a plurality of interconnected blades adapted for rotation within the frame, which operator comprises a pair of pivotally interconnected members operatively associated with the blades of the damper and the damper frame, and an actuator for causing articulation between the operator members, thereby rotating the damper blades between a fully open and a fully closed position. A variety of actuators may be used, including cable-type actuators as well as electrically and pneumatically operated actuators. 
     The operator is configured so that the amount of rotation of the damper blades which is caused by a given amount of operation of the actuator increases as the damper blades move toward the open position, and so that an over-center position is defined wherein the operator members are substantially longitudinally aligned and in which the blades of the damper are locked in position.

Abstract: @ Apparatus for detecting missing areas or folded corners in sheets, for example banknotes (14), is disclosed. Figure 1 shows a banknote (14) being scanned in a strip along one edge of the banknote. A strip light source (12) and a strip sensor (16) are disposed on opposite faces of the banknote which is caused to move perpendicularly to the light path between the source and sensor, and perpendicularly to the plane of the drawing. A photometer (18) responds to the total amount of light transmitted through the edge strip of the banknote (14) as the banknote is scanned. A filter (20) may be inter posed in the light path to improve the sensitivity of the apparatus. The total amount of transmitted light detected by the photometer (18) is integrated over a period of the scan during which the intensity differs substantially from the mean level for an unflawed portion of the banknote. Integration is thus performed only over missing or folded areas of the banknote. It may also be limited to only the leading and trailing portions of the edge strip of the banknote, corresponding to the corners of the note.In order to compensate for the passage of a skewed banknote passing through the apparatus, integration is inhibited over the said period whenever the intensity waveform from the photometer (18) is steeper than a predetermined gradient.
