Title: Means for controlling the supply of liquid fuel to internal combustion prime movers
IPC: F02D1/02
Filed: 1945-10-23
Abstract: 600,522. Fluid pressure servomotors. LUCAS, Ltd., J., and IFIELD, R. J. Oct. 23, 1945, No. 27877. [Class 135] [Also in Groups XXVI and XXVII] The supply of liquid fuel to discharge nozzles located in a combustion chamber is regulated by the pressure drop across two coaxial metering orifices arranged in parallel and having their effective areas varied according to atmopheric pressure, a manually operable valve further controlling the flow through one of the orifices. As applied to a combustion turbine the metering orifices are formed by a slidable plug x co-operating with a fixed plug z, the fuel flowing from a swash-plate pump b to an inlet S and through holes 10 to the first orifice y and through a manually operated valve 2 to the second orifice w, the metered fuel flowing through a pipe t to the nozzles v. The area of the orifices is varied according to atmospheric pressure by capsules 16, 17 controlling through a lever 14 a valve 13 permitting fuel to flow through a passage 11 in a piston 6 attached to the plug x, the resulting pressure difference on opposite sides of the piston causing it to move against a spring 8. The pressure drop across the metering orifices is applied to the opposite sides of a capsule 19 controlling a valve 18 causing a servomotor k to vary the fuel delivery from the pump.

Title: Distance measuring instrument for motor vehicles
IPC: G07B13/04
Filed: 1973-06-13
Abstract: 1381212 Odometers RECORD TAXAMETER AB 13 June 1973 [28 June 1972 (2)] 28114/73 Heading G1K [Also in Division G4]  The distance covered by a motor vehicle is printed, e.g. for taxation purposes, on a card (17) Fig.2 (not shown) insertable into a slot 16 in the casing 19 of distance measuring apparatus comprising an accumulating counter 18 mounted in a frame 8 pivotable on an axle 20 in the casing 19 to move between a protected position (full lines on Figs.3, 5) and a printing position (chaindotted lines) adjacent the slot 16 in which the counter 18 marks the accumulated distance on the card (17), through an opening 30 in the side wall of the slot 16, a guard 27 normally covering the opening 30 and being inter-connected with the counter frame 8 so that it exposes the opening 30 immediately prior to the printing operation and returns to its position covering the opening immediately after the printing operation. The counter 18 drive is taken from a flexible shaft between the vehicle gear-box and a tachometer, and rotates a cam 3, Fig.3, to rock a lever 4 carrying a driving pawl 6 of the counter. When the counter pivots to its printing position, the lever 4 loses contact with the cam 3, rocking under the action of a spring 5, so that any drums advanced only half a step in the counter are advanced to show integral figures prior to printing. The print-actuating mechanism, Fig.4. The axle 20 is cranked at one end and acts as a torsion bar. An elbow linkage 11 connects the crank with a nut 10 on the screwed shaft of a hand wheel 9. With the elbow linkage 11 straight, the hand wheel is rotated to move the nut 10 towards the axle 20, to load it torsionally. At the end of its travel, the nut 10 strikes a lever 23 which, via a shaft 24, releases a retaining pawl 12 of the counter frame 8 so that the counter is pivoted upwards by the torsion bar 20 to press the card (17) between the counter drums and a stamping pad 1. As the counter reaches its printing position, a bar 22 on the frame 8 collapses the elbow linkage 11, allowing a spring 13 to return the counter to its normal. protected position. The hand wheel 9 must be rotated in the opposite direction to straighten the elbow linkage 11 and to re-engage the pawl 12 with the frame 8. In a modification, Fig.7, a pushpull member 33 replaces the screw and nut and hand wheel. A pin 34 on the member 33 engages an inclined slot 35 in a swing arm 32 to which is pivoted one end of the elbow linkage 11. A projection 37 on the linkage trips a release member 38 for the pawl (12). The guard 27 is a flat plate movable in the slot 16 and is pivoted at 28 to links 29 rotatable at their other ends on the shaft 24 of the casing 19, and to a link 26 pivoted at its other end to a bar 25 across the counter frame 8. As the counter is raised to the printing position, the guard is drawn deeper into the slot 16 to uncover the opening 30.
