Title: Colour pictures from electronic video signals
IPC: H04N9/75
Filed: 1976-09-27
Abstract: 1506836 Television systems ASSOCIATION OF MOTION PICTURE & TELEVISION PRODUCERS Inc 27 Sept 1976 [25 Sept 1975] 39945/76 Heading H4F A chroma keying system compensates for colour impurity in the foreground scene backing colour throughout a continuous range of transparency of the foreground scene, and distinguishes between foreground objects of backing colour and flare, i.e. backing colour that appears as edge lighting of a foreground object as a result of scattering. The foreground and background scene video signal generators 20, 40 pass component colour signals R, G, B to a mixer unit 50 which feeds composite scene video signals to a utilization device 70 and a monitor display 68. To compensate for impurity in the backing colour, e.g. blue, the foreground red and green components are modified (A2, A3) by values corresponding to the transparency of the foreground and adjustably derived (R1, R2) from an amplifier A 1. The amplifier forms the difference of the foreground blue component and either the green component, the modified green component, or, if the foreground contains a light blue area, an adjustably (42, A5) greater or lesser proportion of the modified green component. The background scene component signals pass to the mixer unit 50 via amplifiers 71-73 controlled by a signal (S) which is the difference of the foreground blue component and the adjusted modified green component. To compensate for flare the foreground blue component passes to the mixer unit via a circuit 60 which modifies it such that it can exceed the green component only to the extent that the green exceeds the red component (62), and further such that it cannot exceed the adjusted modified green component (A5). This allows foreground blue objects to be reproduced correctly but prevents blue flare into flesh tones and white.

Abstract: 952,276. Coffee-making machines. P. E. JANNIN. Oct. 25, 1962 [Oct. 31, 1961], No. 40494/62. Heading A4D. In a coffee-making machine, hub 21 rotates about the shaft of a driving motor 16 and carries four filter holders in turn beneath each of four processing stations of the machine. When the machine is started by a coin freed arrangement, the processes of supplying a holder with coffee grains, tamping the grains by means of an electromagnetically operated plunger 89, at B, percolating the grains with hot water, at C, and washing out the spent grains by means of a sprinkler rose 121, at D, are carried out simultaneously on each filter holder. The coin momentarily closes a motor starting switch and the shaft of motor 16 begins to perform a single revolution, during the first part of which hub 21 is keyed by downward movement for rotation with the shaft for a quarter turn thereof and, thereafter, is allowed to rise under spring action to disengage from the shaft. Each filter holder is thus moved to the adjacent processing station and the remainder of the revolution of the motor shaft operates switching cams to bring about the four processes. In the percolating station a cam operated finger 105 presses the holder into liquid tight engagement with the boiler 101 and the boiler valve 102 is operated twice. The first flow of water moistens the grains and is followed by a pause which allows them to swell. The second flow produces a cup of coffee and can be prolonged by means of a pushbutton control. Syrup is simultaneously supplied from tank 132.
