Abstract: 1,055,359. Flint feed mechanisms. COLIBRI LIGHTERS Ltd. Nov. 1, 1965 [No. 26, 1964], No. 48131/64. Heading F4F. A cigarette lighter flint feeding mechanism comprises a cylinder formed by upper and lower parts 13, 12 closed at its lower end containing an annular piston 19 which slides around a sleeve 16 containing a second piston 22, the sleeve 16 being fixed at its top end to the upper part 13 of the cylinder but being free at its bottom end. The volume below the two pistons is filled with a light oil and a compression spring 25 within the cylinder above the piston 19 causes the oil to exist under pressure which forces piston 22 upwards in sleeve 16 and holds a flint 24 in contact with an abrasive element 10 of the lighter through the top of the cylinder. The, areas of the pistons 19 and 22 in contact with the oil are in the ratio of 6: 1 and the sliding surfaces of the pistons are formed to retain sealing O-rings 20, 21 and 23. The flint feeding mechanism is mounted in a tubular housing 4 extending through the lighter fuel reservoir 7 and is screwed to the lighter by means of a threaded nose 30 of the cylinder. A fingerpiece 29 is mounted on the bottom of the cylinder. In a second embodiment, Fig. 3 (not shown), a cylinder 33 contains an inner flint supporting sleeve 34 closed at its lower end and formed at its upper end with an annular piston 36 which surrounds flint 35 and slides within the cylinder 33. The upward movement of the sleeve 34 is limited by an end closure cap 40 screwed to the cylinder 33, and removal of this cap will withdraw the sleeve 34 from cylinder 33. Air trapped above the piston 36 is compressed by the action of a compression spring 42 on the piston, the spring being held between the underside of the piston and the top of the cap 40. The pressure of the air acts on the underside of the flint 35 to force it against an abrasive element 10. Sealing 0-rings 44 are mounted in the neck 43 of the cylinder 33 through which the flint passes. In another embodiment, not shown, a flint tube is in communication at its lower end with a rubber balloon containing a pressurized fluid which forces a flint against a flint wheel.

Title: Improvements in or relating to Methods of and Apparatus for Operating a Thrust Producing Engine
IPC: F02D9/00
Filed: 1966-11-09
Abstract: 1,169,921. Automatic control of engines. OPTIMIZER CONTROL CORP. Nov. 9, 1966 [Nov.9, 1965], No.50299/66. Heading G3R. The thrust controller of a reaction type propulsion engine for a vehicle is oscillated continuously and signals corresponding to the senses of variation of the controller and the velocity or acceleration of the vehicle are compared to produce a signal which adjusts the controller to a maximum thrust position. In Fig. 1, the thrust of a propulsion engine is oscillated above and below a mean value by a controller 8. The resulting effect on the vehicle propelled by the engine is detected by a damped accelerometer 3 which, through a transistor relay 6, produces a signal 15 on increase of acceleration and a signal 16 on decrease. The latter signals are compared with signals 9 and 10 which are produced on movement of controller 8 in one direction or the other. The comparator 7 determines from the signals which direction of movement of controller 8 effects an increase in of acceleration and hence thrust, and then operates a servomotor 11 to adjust the mean setting of controller 8 in this direction so that engine thrust becomes a maximum. An arrangement in which there is continuous alternating adjustment of two engine variables under the control of a single accelerometer to get maximum engine performance is referred to.
