Patent GB-2102532-A (GB)
Title: Differential gear reducer
Inventor: NICKOLADZE LEO G
IPC: F16H1/24
Filed: 1982-07-30
Abstract: In a gearing mechanism wherein one gear (11) of a smaller diameter engages in partial mesh another gear either in the form of a rack (20) or a gear of a larger diameter, the pitch of the smaller diameter gear is made different than the pitch of the rack or the larger diameter gear thus achieving a pitch differential. To accommodate this inequality in pitch the teeth of the smaller gears are radiused (at 31) and the larger gear or rack may include rollers (22) which engage these rounded teeth to accommodate the difference in pitch by relative movement. In alternative implementations the smaller gear, rather than including teeth, may include a plurality of permanent magnets, once more distributed at a pitch different than a plurality of permanent magnets embedded in the larger gear or rack. The coercive force between the magnets can thus be used to transmit power at a gear ratio equal to the pitch differential. <IMAGE>

Title: Coin recognition
Inventor: CHAPMAN COLIN KENNETH LEONARD
IPC: G07D5/08
Filed: 1984-02-08
Abstract: Coins are recognised by monitoring the decay of an eddy current induced therein. In a preferred embodiment a coin is placed in inductive relationship with a coil 10 and a pulse of 1 to 100  mu s is applied.The decay of the eddy current induces a signal in the coil and instantaneous values are recorded, e.g. at 10  mu s, 25  mu s and 45  mu s after the pulse. The coin is recognised by comparing these values with stored values characteristic of various denominations. The characteristic values are conveniently obtained by operating in a learn mode in which coins of known denominations are measured and the maximum and minimum values are stored as the characteristic values. <IMAGE>
