Title: Shape recognition systems
IPC: G01B11/245
Filed: 1972-02-12
Abstract: 1398720 Shape recognition LUCAS ELECTRICAL CO Ltd 2 Nov 1972 [16 Nov 1971] 53027/71 and 6680/72 Heading G1A In a shape recognition system, as an article (9) Fig. 2 (not shown), moves in front of an array of photo-cells (11), if the correct shape is detected by the cells, logic circuitry gives an output signal to for example increment acounter. As described in the embodiment of Fig. 1 in which 24 photo-transistors 11 are mounted on a board in front of which the articles are moved, the photo transistors 11 are connected via associated two-position switches 21 to NAND gates 25, 26, 27, the outputs of which are connected to a further NAND gate 35. To set the apparatus up, an article of the shape to be recognized is positioned in front of the photo-transistors. All the transistors then receiving light have movable contact 22 of their associated switch 21 positioned on contact 24 so that, with transistor 15 conducting as a result of the applied light, a "1" signal is applied at the output of the switch. All the detectors not receiving light have the contact 22 positioned on contact 23 so that, with transistor 15 non conductive and transistor 18 conductive, a "1" signal is again applied at the output of each switch. The gates 25, 26, 27 thus have "1" signals on all their inputs the resulting "0" outputs after inversion by transistors 32, 33, 34 resulting in the disabling of gate 35. Transistor 36 is consequently turned on so that current flows through resistor 37. After the apparatus has been set up the articles may be moved on a conveyer in front of the phototransistors and whenever the pre-selected arrangement of lit and unlit photo-transistors occurs, the resulting voltage across resistor 37 increments a counter. Alternatively the counter may be replaced by a warning device or an arrangement for diverting incorrectly shaped components. In a modification the photo-transistors are positioned remote from the article, the light being conducted to them by optical fibres. Alternatively if a magnified or reduced image of the article is required a lens system may be positioned between the articles and the detectors.

Title: Improvements relating to radio receiving sets
IPC: H03D7/10
Filed: 1937-03-10
Abstract: 490,244. Valve circuits for wireless reception. COLE, Ltd., E. K., and BROOKE, H. A. March 10, 1937, No. 7007. [Class 40 (v)] In a radio receiver comprising an oscillatormixer circuit to which automatic volume control is applied, frequency drift with change in signal strength is reduced by connecting a resistance R2 between the screen grid G4 and the oscillator grid GT. An increase of signal strength causes grids G4, GT to become more positive with the result that the impedance in shunt with the oscillator tuned circuit is reduced, thus compensating for the decrease in capacity which is otherwise produced. Resistance R3 is connected to earth or chassis instead of directly to the cathode and is of the order of 0À5 megohm. The oscillator-mixer may comprise a triode-hexode as shown, or two separate valves.
