Title: Improved hydrofoil keel
Inventor: SIMS MERRICK LEVISON
IPC: B63B3/38
Filed: 1985-02-12
Abstract: A hydrofoil shaped keel for sailing craft designed to minimise the yaw angle and to maximise the boat speed when boating, by a combination of the following novel features: The creation of a vorticity reducing channel or trap along the lifting surfaces by increasing the thickness/chord ratio of the keel section from the top of the keel to the foot. The arrangement of the ratio of keel lifting surface area to sail area so that the keel operates close to that angle of attack giving its highest lift/drag ratio throughout a given wind speed range. By variation of the keel surface area to vary the wind speed range in which it operates as above. By variably cambering the keel section through novel means, to further increase keel lifting capacity and to reduce the angle of attack at which its highest lift/drag ratio occurs, thus further reducing the boat's yaw angle.

Title: Identifying the position of objects or zones
Inventor: SMITH MARTIN PHILLIP
IPC: G01S17/06
Filed: 1989-05-05
Abstract: In order to identify diamonds in gangue, incident radiation from laser 3 is scanned along an extended line across particulate gangue, and the diamonds 2 are identified by detecting the Raman radiation which is emitted, using a narrow pass band filter 9 in order to block out other radiation. In order to identify the position along the scan line from which the Raman radiation was emitted, the incident laser radiation is pulsed at a pulse frequency which changes along the scan line, and the frequency of the Raman radiation detected is sensed. In this way, one can simplify the equipment needed. <IMAGE>

Title: Coin discriminator
Inventor: HENDERSON ANTHONY
IPC: G07D5/02
Filed: 1989-12-05
Abstract: A coin discriminator has an opening 2 to receive a coin. Entry of the coin pushes back a slider 4 to enable the coin to pass along a coin rundown path 5 to a pivotally mounted sensing arm 6 that is connected to a pivoted vane 8. The coin pivots the arm 6 by an amount dependent upon the diameter of the coin, and this movement is converted into a larger movement of the outer portion of the vane 8. The displacement of the vane is detected by an optical detector 10 which produces a number of electrical pulses dependent upon the number of holes 9 which are swept past it. Electrical contacts (17, 18) (Figure 3) are utilised to test whether the coin is metallic. <IMAGE>
