Title: Fuel injection nozzle units
IPC: F02M61/20
Filed: 1971-10-30
Abstract: 1406216 Fuel injection nozzles CAV Ltd 17 Oct 1972 [30 Oct 1971] 50534/71 Heading F1B A liquid fuel injection nozzle unit in which a valve member shaped to co-operate with a seat is moved by fuel pressure against resilient means away from the seat, is characterized in that a fluid pressure operable means is provided to which fuel under pressure, leaking between the valve member and a bore in which it runs, is led,the means being coupled to the valve member so that the fuel under pressure assists the action of the resilient means in closing the valve member on to its seating valve means being provided for controlling the pressure of fuel applied to the fluid pressure operable means. The unit comprises a body 10 against the lower end face of which a nozzle head 12 is held by a screw cap 13. A valve member 14 slides in a bore in the body and cooperates with a seating in the head 12. A fuel space 16, communicates by passage 15 with pump 30. Fuel pressure lifts valve member 14 against a spring 19. Fuel which leaks past valve member 14 is conducted by a passage 23 to the chamber 20 and acts on piston 18, the lower end of which bears against push rod 21, so that the fluid pressure produces a force acting in the same direction as the spring. The maximum pressure in the chamber 20 is limited by a valve 24 consisting of piston 25 which is moved to the right (in the Fig.), by the fluid pressure, against a spring. Excessive pressure moves the piston so that fluid exhausts between the edge of a formation in the piston and the shoulder formed by a step in the cylinder. Fluid from the chamber beneath the piston 18, drains through a passage 26 at a rate controlled by a restriction 27. When the engine is started from rest, only the spring 19 resists the valve opening movement, the fluid pressure in chamber 20 increasing with engine speed. In a modification the piston 18 is replaced by a diaphragm.

Abstract: 1469268 Electric control of ship propulsion BOEING CO 27 Nov 1974 [10 June 1974] 51485/74 Heading G3N A combined control system for a reverser bucket and a prime mover throttle control on a hydrofoil craft employs potentiometers mechanically linked to a manual control and having non-resistive contact sections to provide control of the bucket position when the prime mover is idling and subsequent control of the throttle valve when the bucket is positioned. As shown the potentiometer 76 is used to control the energization of the throttle control valve 108 of the prime mover 58 driving the pumps 56 which provides the propelling water jet 40 and for this purpose is provided with a contact section 88 at the centre of travel of wiper 72. The potentiometer 78 controls the bucket position and has a centrally disposed resistive section 110 flanked by contact sections 112, 114 so that movement of throttle lever 68 from the central point causes the bucket drive valve 60 to be moved until the reset potentiometer wiper 132 is balanced with the potentiometer wiper 74. A manually controlled switch 138 connects the bucket control mechanism to pre-set potentiometric chain 120, 122, 124 to hold bucket 46 stationary so that prime mover starting and running can be controlled by the throttle. In operation the prime mover idles at 6000 rpm during movement of the buckets to select forward or reverse motion and then speeds up as wiper 72 contacts section 96, 94 to 13,250 rpm ahead or 7,600 rpm astern respectively to increase the speed of the jet and thus the speed of the hydrofoil.

Title: Exposure delay mechanism for a camera shutter
IPC: G03B9/64
Filed: 1976-12-17
Abstract: 1525320 Shutter delay mechanism SEIKO KOKI KK 17 Dec 1976 [19 Dec 1975] 52792/76 Heading G2A A delayed action mechanism for shutter release is such that the shutter may be prevented from opening after the release button has been pressed, if desired, and which mechanism may be charged to any extent desired. The mechanism shown is mounted on an upper plate 1 and a lower plate 1b. A driving shaft 2, spring-urged clockwise, carries a gear 3 and a cam 8. To charge the shaft 2 it is rotated anti-clockwise, so that a second gear 4 engaging with gear 3 is moved bodily to the left, since its shaft 4a can slide in a slot 1a. This disengages gear 4 from a third gear 5. Movement of shaft 4a also pivots a detent 13 clockwise, which allows a spring-urged locking lever 11 to pivot clockwise. This in turn engages and pivots an anchor 7 into a position where it locks a toothed star-wheel 6 against rotation. An arm 8a on cam 8 rides past an arm 9b of an operating lever 9 into any position between arm 9b and a stop 16. The mechanism is now in the charged position of Fig. 1. On pressing the release button 12, lever 11 is pushed anti-clockwise, which releases detent 13 to pivot anti-clockwise under its spring loading. Detent 13 engages shaft 4a and pushes it to the right, and also latches behind lever 11, thus preventing any possible clockwise movement thereof. Anti-clockwise movement of lever 11 also releases anchor 7 from its locking engagement with star wheel 6. Movement of shaft 4a to the right also brings gear 4 into engagement with third gear 5 which is in engagement with a pinion portion 6a of star-wheel 6. Thus as driving shaft 2 is rotated clockwise by its driving spring, all the gears 3, 4, 5, 6a rotate. This is the running down position of Fig. 2 (not shown). Gear 3 and cam 8 are rotating clockwise with shaft 2, so that arm 8a engages and pushes lever 9 anti-clockwise. The other end 9a of lever 9 is engaged in a notch of the shutter release rod 10, so the latter is driven downwards, thus releasing the shutter to effect an exposure. If it is desired to prevent a picture being taken after button 12 has been pressed but before the shutter opens, shaft 2, and hence cam 8 and gear 3, are rotated anti-clockwise. This causes shaft 4a to move to the left, pivoting detent 13 clockwise, which has the effect, as described above, of moving anchor 7 into its locking position. As soon as the anti-clockwise force on shaft 2 is released, the mechanism is once more locked in a fully or partly charged position.
