Abstract: 743,627. Dispensing liquids. BATES, G. April 2, 1954 [Dec. 2. 1953], No. 33441/53. Class 116 Liquid dispensing apparatus having a rotatable member driven at a rate proportional to the rate of liquid delivered in measured quantities has a control device for automatically limiting the maximum quantity delivered which comprises a support structure attached to the apparatus and mounting a first unit rotatable by the rotatable member and a second unit rotatable by the first unit, a cam on the second unit to operate an electric switch ; for stopping delivery and a lost motion drive connection between the units whereby the rotation of the second unit is arranged to secure after a period of rotation of the first unit substantially'equal to the period of operation for delivery of the given quantity. As shown in Fig. 1, a housing 3 contains a mercury or micro switch 8 in the motor circuit operated by a plunger 17 contacting a cam 15, having one flat surface 16, mounted on a spindle 12 mounted in the housing and rotatable by a disc 32. A spindle 5 coaxial with the spindle 12 carries a gear 6 clutched to the spindle by a friction clutch 7. The spindle 5 also carries a notched disc 18 and the spindle 12 has a projection 27 engageable by pawls 24, 26 mounted on a shaft 25 and urged to engage by a spring 28 to position the spindles initially. The disc 18 has a peg 20 and the spindle 12 also carries a disc 19 with a peg 21. The disc has a notch engaged bv a spring-pressed plunger 33 to brake the spindle 12. The spindle has a ratchet 29 engaged by a spring-urged pawl 30 to prevent rotation of the spindle in one direction. The gear 6 meshes with a gear 36 driven by the liquid flow. It is arranged that when the correct amount has been delivered the spindle 5 has made one complete rotation. This may be adjusted by varying the gear 6 or by arranging other pegs in the disc 19. If too much liquid is delivered the peg 20 engages the peg 21 and drives the shaft 12 so that the plunger 17 is raised from the flat surface of the cam 16 and the switch is operated to stop delivery. To reset the device the shaft 12 is rotated by the disc 32 until the pawls re-engage; this is also done even if the safety device has not been operated to cut out the motor. The plunger may be replaced by a flat pivoted arm.

Abstract: 1,270,597. Automatic focusing. EASTMAN KODAK CO. 3 July, 1969 [9 July, 1968], No. 33568/69. Heading H4D. [Also in Division G2] Specification describes an automatic rangefinding and focusing arrangement particularly for use on a camera and comprising a pivoting mirror 70, Figs. 2 and 7 scanning a beam of light from a modulated light source 94 across a subject plane and a receiving lens 26 directing light reflecting from the subject S, visually positioned directly in front of lens 26, on to two photo-detectors 116, 118, an electronic 106 circuit detecting and producing an output when the detectors are equally illuminated indicating that the light beam is directed at the subject, said output stopping the movement of the mirror 70. Pivotal movement of the mirrors is coupled with rotary movement of a cam 32, the surface 36 of which controls the position of the focusing lens 12. In detail the cam 32 is initially rotated anticlockwise against spring 34 and locked in position by tooth 76 engaging in rack 80. To start the automatic focusing button 20 is depressed, releasing tooth 76 and allowing the cam to rotate clockwise. This causes three actions:-(a) contacts 52 are closed by cam surface 50 whereby electrical energy is supplied to circuit 106 and to light source 94; (b) chopper read actuator 58 is pivoted about 60 by means of follower 56 and cam groove 54, whereby a read 102 is vibrated to amplitude modulate the light beam from source 94, and (c) mirror 70 commences to turn about 68 by means of follower 64 riding slot 62 and scan the modulated light beam. Part of the light beam is detected by means 104 and a signal fed to circuit 106 for synchronous demodulated of the reflected light beam signal. When photodetectors 116 and 118 are equally illuminated circuit 106 (Specification 1,270,596) feeds a signal to solenoid 82 whereby plunger 84 moves to cause tooth 86 to lock into rack 80 and stop the cam rotation. Button 22 is now depressed, moving lever 44 and releasing lens 12 whereby it moves under the action of spring 42, until follower 38 abuts cam surface 36 marked in range units. Button 22 also actuates the shutter release lever 124.
