Title: Improvements in or relating to the sensing of the position of a movable member in a gaming or amusement machine
IPC: G07F17/34
Filed: 1980-07-16
Abstract: In a gaming or amusement machine a reading voltage is applied to an electrical contact (1) associated with a movable member of the machine to determine the state of the contact and thereby the state of the movable member. The state of the contact (1) is evaluated by a computing unit with an input chip (16) having an operating voltage much lower than the reading voltage. At the end of a game the computing unit sends a strobe signal to a sampling switch (4) connected to a pole (2) of the contact (1) causing the switch to close briefly. If the movable member is in a winning position, the contact (1) will be in a closed position and currently will flow through the contact thereby flowing through a resistor (7) and a driver component (14) of an opto-coupler current detector (8) connected in series with the contact. The receiver component (15) of the detector (8) provides the computing unit with a detection voltage compatible with the operating voltage levels of the computing unit and electrically isolated from the reading voltage. <IMAGE>

Title: Method and Apparatus for Detecting Level of Molten Metal in Steel Manufacturing
IPC: B22D11/16
Filed: 1980-10-03
Abstract: In continuous casting, the level of molten steel 2 in mould 4 is detected by taking images of the free surface 5 with video camera 6, scanning lines substantially in parallel with the free surface.
