Abstract: 1,267,041. Wind direction indication. PLALITE Ltd. April 30, 1970 [Jan.30, 1969], No. 5127/69. Headings G1N and G1R. [Also in Division G4] An apparent wind direction sensing apparatus for use on a wind propelled vessel or vehicle comprises a wind direction sensing device 12 which provides a signal to an indicator (50, Fig. 3 not shown) when the wind is within one of the two non overlapping ranges of apparent wind direction when the vessel or vehicle is beating to windward, the indicator indicating at least the sense of deviation from a specific preferred wind direction in the respective range, only when the wind direction is within the range. As described the apparatus is arranged for defining in addition a third non overlapping range of apparent wind directions with a corresponding specific preferred apparent wind direction, corresponding to the vessel or vehicle running before the wind. The wind direction is sensed by a vane 14 on a rotatable shaft 32 to which is attached an electrical contact wiper 22 which sweeps over contacts on circuit board 18. The contacts are arranged in three groups A, 1a-7a B 1b-7b C 1c-7c corresponding to wind directions from ahead and from aft. Corresponding contacts are connected, and triplets of corresponding contacts are interconnected by equal resistances R 1 -R 5 . The contacts are connected in a Wheatstone Bridge circuit with equal resistances R 11 -R 16  and a centre reading galvanometer 60 set to read zero when the contact wiper 22 is at the specified preferred wind direction contact (e.g. 4a or 4b or 4c). Switch S 2  enables one or other of the contacts besides the 4a, 4b and 4c contacts to be selected to indicate different specified apparent wind directions. This arrangement is such that whilst the vane 14 indicates the correct heading of the vessel or vehicle, relative to the wind the galvanometer remains centered. When the wind bears away from this heading, the galvanometer is unbalanced and indicates accordingly. Instead of the Wheatstone Bridge arrangement, each contact may be connected to an indicator light, the central, coloured one indicating the specified preferred apparent wind direction (Division G4).

When the tube includes a rectangular shadow mask 3 attached to a frame 4 a screen 13 may be attached to the frame to protect the seal 6 from electron bombardment. The screen 13 may be provided only at the four corners or may extend all round, and a flange may extend to the envelope, as shown in Fig. 6, to prevent electrons from passing round the side of the shadow mask. An alternative method of preventing the seal from charging consists in making the seal of conductive material, or of providing a conductive coating over the seal to extend between the usual conductive coatings provided on the faceplate and on the cone. Such a coating may be provided by means of an evaporator on the frame 4 which is fired like a getter. Alternatively an evaporator may be introduced into the neck of the tube to evaporate aluminium over the seal.

Title: Coin-reception devices for coin-freed mechanism
IPC: G07F5/02
Filed: 1970-05-08
Abstract: 1316092 Escrow mechanism ICE-MATIC Ltd 8 May 1970 19825/69 Heading G4V In a coin- or token-freed mechanism one or more coins inserted in an inlet 9 enter and are supported in a first coin passageway 9a by a hook 21a, and stored until a further coin is diverted by the or the uppermost coin into a second coin passageway 10 to trip a lever 24, and so retract the coin supporting hook 21a to release the stored coins through an exit 13. The stored coin or coins can alternatively be released for return to an operator through a side opening 12 adjacent the lowermost coin, after retraction of a gate 40. The supporting hook 21a and lever 24 are coupled by a rotatable bar (16) (see Fig. 2, not reproduced) and biased into the coin passageways by a counterweight (27) or springs. After tripping the lever 24(Fig. 1) the diverted coin operates a microswitch (29) (Fig. 3, not reproduced) arranged in or below the passageway 10 (Fig. 1), to free associated mechanism. The gate 40 is coupled to a normally retracted second gate 43 by a rotatable counterweighted or spring-biased bar 32. Manual operation of the bar 32 retracts the gate 40 and moves the second gate 43 to block the entrance to the second coin passageway 10, so that all inserted coins pass into the first passageway 9a and are returned. If a coin is being diverted as the bar 32 is rotated, the coin is jammed between the second gate 43 and a partition 15, so preventing complete retraction of the gate 40; release of the bar 32 is then followed by normal operation of the lever 24 and supporting hook 21a. The mechanism may be adapted for storing different numbers of coins by altering the length of the hook 21a. Specification 967,939 is referred to.
