Title: Improvements in or relating to devices for governing and controlling ships engines and variable pitch propellers
IPC: B63H3/10
Filed: 1964-12-10
Abstract: 1,093,950. Controlling variable pitch propellers. KARLSTADS MEKANISKA WERKSTAD A.B. Dec. 10, 1964 [Dec. 11, 1963], No. 50230/64. Heading B7V. Apparatus for governing and controlling a ship's engine speed and propeller pitch comprises devices which sense engine temperature and/or engine load to - influence by signals the extent of control of the fuel supply and propeller pitch so that engine speed does not become too high and the engine is not overloaded before working temperatures have been reached. Compressed air is supplied by piping 11a to inlet valves of a fuel supply adjusting device 2 and a propeller pitch setting device 3 both of which are controlled from instrument 1. Pneumatic signals are emitted from the controller 1 via line 9 to a known balancing valve arrangement 12 which is supplied by means not shown with hydraulic fluid under pressure and which is connected via lines 14, 15 to opposite ends of a cylinder 17 containing piston 16. The position of piston 16 in the cylinder is arranged to affect the pitch of the propeller 22 and pistonrod 18 is arranged to actuate the lever arm 13 via an arm 20 in the form of a cylinder pivoted at 19 and via arm 20 in the form of a piston in that cylinder. The assembly 12-21 forms a servomotor and feed-back line in which lever arm 13 actuates valve 12 in the opposite direction to that initiated by line 9 from the control instrument. Engine temperature sensing device 24, engine loading sensing device 25, speed control device 29 and a second engine temperature sensing device 32, together with fuel supply adjuster 2 are interconnected in various ways so that excessive temperature and/or engine loading caused by excessive speed in the circumstances can feed back through line 23 for the correct balance in valve 12, in propeller pitch and/or in fuel supply to be restored. Actuable device 4 can, if necessary, be brought into operation to by-pass the governing devices.
Patent GB-509265-A (GB)
Abstract: 509,265. Gas-lighters. PARKINSON STOVE CO., Ltd., COX, F. L., and SMITH, R. E. Jan. 14, 1938, No. 1255. [Class 75 (iii)] A gas torch 15 is connected by a flexible tube 14 to a gas cock 12 which allows a relatively large flow of gas when the cock-plug 13 has still a substantial part of its opening movement to make so as to ensure gas issuing from the torch before a friction-wheel 31 is actuated through a trip device at the end of the opening movement for igniting the torch. As shown, the transverse bore 20 of the cock-plug opens into shallow depressions 21 which restrict the flow of gas at the end of the opening movement. The amount of gas passing to the torch in the final position can be varied by adjusting a setscrew 25 engaged by a radial abutment on the cock-plug. The friction-wheel 31 and flint tube 30 are mounted on a carrier 17, secured to the cock-plug and formed with a socket 19, in which the torch is detachably held as by a spring-pressed ball catch so as to constitute the operating lever for the cock. The frictionwheel is connected to a rotatable spindle 33 on the carrier through a one-way coupling consisting of a roller 35, housed in a wedge-shaped opening 34 in a sleeve 32 and co-operating with the serrated inner surface of the wheel. On opening the cock, a spring-pressed pawl 38 on the spindle 33 is held by a cranked lip 39 on a gas-collecting hood 40 to tension a spring 41 until, at the end of the movement, the pawl rides off the lip and allows the spring to actuate the wheel 31. The mechanism is preferably enclosed in a detachable shield which slides on to the carrier. Specifications 486,686 and 493,110 are referred to.

Title: Improvements in or relating to containers
Inventor: MITCHELL JOHN ROTHWELL
IPC: B64D17/78
Filed: 1965-01-29
Abstract: 1,137,503. Dropping by parachute. G. Q. PARACHUTE CO. Ltd. 25 Jan., 1966 [29 Jan., 1965; 12 Feb., 1965], Nos. 52723/65 and 6261/65. Headings B7G and B7W. A container for articles dropped from the air is provided with means for transmitting two different forms of signal such as a visual signal and an audible signal or two different forms of visual signal and with means for attaching one or more parachutes for supporting the container during at least part of its journey to the ground. One form of the container (Fig. 1) comprises a case 11 fitted with a lid 12, an audible signalling device 14, lamps 15, 16 and batteries 20, 21. The lid 12 carries a contact bar 19 for connecting the batteries 20, 21 to the signalling device 14 and the lamps 15, 16 and a switch 18 which can be moved to insert the device 14, the lamps 15, 16, or both, into the circuit. A main switch 17 can be operated by hand when the container is about to be despatched or can be arranged to be operated when a parachute to which the container is attached is deployed. A modified form of container (Fig. 5) has two compartments 57, 58, the latter housing the container shown in Fig. 1, with the lamps protruding as shown at 40, 41. The compartment 58 is closed by flaps 49, 50 carrying rubber pads 51, 52. The compartment 57 houses a parachute and is closed by a flap 43 to which the parachute is connected. Two handles are provided, the handle 44 which is attached to the container being smooth and shorter than the other handle (not shown) which is attached to the apex of the parachute and has a bulged end. When the container is thrown towards the target, the smooth handle 44 is released by the user but the other handle is retained, the bulged end assisting the user to retain this handle. The inertia generated drags the parachute from the container. When the parachute is deployed, a second snatch occurs which first operates the switch 18 (if this is arranged to be operated when the parachute is deployed) and then pulls the other handle from the grip of the user. The container then floats to earth supported by the parachute through rigging lines and a bridle 59, which passes through a loop 60 formed in the flap 43. If the signalling device in use whilst the container is falling is a visual device, its path can be watched from above and below. When the container is on the ground its signalling devices enable it to be quickly and easily located. Such a container can be used as a training device or as means to enable a group of parachutists to keep together if they are falling at night or in cloudy or foggy conditions.

Abstract: 1279728 Cinematographic apparatus EASTMAN KODAK CO 30 Oct 1969 [31 Oct 1968] 53251/69 Heading G2E A cine projector includes a mechanism for separating leading end of the roll of film on a supply reel and comprises a stripper 35 movable about pivot 70 to engage the periphery of the roll 28 and separate the free end of the film as the roll is rotated in the unwinding sense by frictional engagement of the roll periphery by a driving belt member 34 pivotable at 49, movement of stripper 35 and member 34 to their operating positions being effected by a manually operable lever 17. A drive control member consisting of a rod 129 rotatable about its longitudinal axis to "forward" or "reverse" positions as an end 132 is engaged by a cam surface 133 of interlock lever 124. When projection is completed film tension increases to depress snubber 83 whose pin 134 displaces a trigger surface 135. This displacement disengages trigger latch tooth 121 from a support plate 118 which then pivots anti-clockwise about stud 119 to displace interlock lever 124 and hence cam 133 to shift rod 129 to the "reverse" position. The movement of plate 118 also shifts lever 107 whose fingers 108, 109 open the spring-loaded halves 91, 95 of the gate as the projector enters the rewind mode. Manual control of rod 129 is possible by use of pin 134. A spring-loaded re-view handle 18 may be manually turned to pivot interlock lever 124 and so shift rod 129 to the "reverse" position. The projector then re-winds until handle 68 is released when forward drive re-commences.
