Patent NL-7708309-A (NL)
Inventor: DUTILLOEIL GEORGES
IPC: H03D1/22
Filed: 1977-07-27
Abstract: The logic circuit has more than two separate conductors each connected to a common conductor via a resistor and a diode. The independent conductors are selectively connected to two differential potentials which represent possible values of logical variables. An input (2) of a detector circuit with a transistor amplifier is connected to the common conductor in a logical negation circuit. The common conductor, which is connected to the control electrode of the amplifier, will determine the setting potential for the operating point of the amplifier. An alternating signal offered to the input produces an alternating signal at the output when the woring point is in the amplifier region of the characteristics whereas the amplifier will be bottomed or saturated if the operation point outside of the amplifying region. This means no signal output.

Patent NL-8001149-A (NL)
Title: Protection device for slot of parking meter or vending machine - prevents insertion of anything other than magnetisable coin or token by using magnetically actuated shutter mechanism
IPC: G07F1/02
Filed: 1980-02-26
Abstract: This slot meter protection device allows the insertion of fully magnetisable coins or tokens, but will prevent the insertion of keys, ice-lolly sticks, beer-car rings, in appropriate coins, etc. When the edge of a suitable coin is pressed into the opening of the slot, a permanent magnet (8) is attracted to the coin, and moves downwards against the pressure of a spring (11). A recess (12) in the magnet then allows a ball (4) to move out of a depression in the sealing shutter (2) at the back of the slot. The coin then pushes up the shutter via a pair of ball-bearings (14), rods (15), a yoke (17) and a lever (18). A non-magnetisable coin cannot get past the ball-bearings (14) as the shutter is locked in position by the small ball (4), thus preventing the lever, yoke and rods from moving, while the shutter itself prevents any narrow instrument from reaching the inside of the meter.
