Title: Improvements in or relating to control mechanism for motion picture apparatus
IPC: G03B19/18
Filed: 1963-09-17
Abstract: 1,043,388. Cine cameras; control mechanisms. EASTMAN KODAK CO. Sept. 17, 1963 [Sept. 24, 1962], No. 36529/63. Heading G2E. A cine camera has a control mechanism which is actuated by a trigger 20 and which permits continuous or single frame exposures to be made, the kind of exposure being determined by the setting of slide tab 26. Pin 106 carried by the rotating blade shutter 22 describes a circular path about the axis of the shutter, an overcentre spring 86 moving a pivotally mounted blocking mechanism into and out of the path of the pin to control the shutter movement. The mechanism comprises two overlying spring steel members 74 and 88 normally biased away from each other and a catch 102 which normally latches the members together for movement as a unit by engagement with the tab 98 on stop lever 88 which projects through cut-out 100 in blocking member 74. In the OFF position the mechanism is toggled so that lever 88 is in the path of shutter pin 106. In the RUN position the mechanism is toggled by spring 86 to pivot about the ears 76 and lever 88 is moved forward out of the path of pin 106 thereby starting motor 24 and the shutter rotates until the trigger is released, U-shaped spring member 34 thus moving trigger 20 outwards to the OFF position so that spring 86 snaps member 74 back to the Fig. 5 position. For SINGLE FRAME operation, the blocking mechanism moves to a limited extent decided by the setting of slide member 112 controlled by slide tab 26, the tab being moved laterally to the left until the rearmost stepped surface 128 on stop member 124 engages the front surface 130 of member 74 when the trigger 20 is depressed. Shutter pin 106 is released and the shutter makes one revolution until the pin engages cam surface 108 of latch 102, which has remained in its path, and moves the latch out of engagement with tab 98 so that lever 88 snaps back into the path of pin 106 and stops the shutter. Lever 88 has a depending tab 92 which engages contact arm 94 when the lever is moved rearwardly so as to open switch 96 and stop the motor 24. When tab 26 is in its central LOCK position, the legs 114 of slide 112 are in the path of movement of projections 118 on trigger 20, and the trigger cannot be depressed. The tab is moved laterally to the right for RUN operation and projections 118 are no longer blocked, while step surface 126 of stop member 124 is positioned to engage surface 130 of member 74. Handle 30 operates on optional trigger latching device. In an embodiment, the blocking member has pivotally mounted on it, a stop lever which also comprises a switch element for the motor circuit and which eliminates the need for a separate latch to hold the two members together.

Abstract: 1279851 Combination locks P BOUDIN J DE LAREBEYRETTE and M LIESSE 22 July 1969 [29 July 1968 5 Dec 1968] 36761/69 Heading E2A [Also in Division B8] A tube for obnoxious materials e.g. drugs, which are dangerous to children, is provided with a closure which can only be removed by performing a number of sequential operations. The closure may be fastened to the container by a simple translatory movement. A tube container has two tabs 4 and 5 (Fig. 1) with lugs 3a and 3b. The closure comprises two parts 6 and 11, part 6 having a ring 7 integral with it and provided with a gap 9. Part 11 constitutes a second ring with a gap 13 in it. The two parts of closure may be fastened to the tube by simply pressing them down over the end of the tube, deflecting the two tabs 4 and 5 in the process. To remove the closure the parts 11 and 6 must be rotated independently with each other until the lugs on parts 4 and 5 correspond with the notches 9 and 13 in the rings 7 and 12. The tap may then be lifted until lug 3a engages ring 12. A further rotation of ring 12 is then necessary to allow removal. The space at the bottom of the container closed by a simple slide top, may contain highly coloured harmless pills capable of staining the fingers thus indicating that the child has been playing with this type of container. In Figs. 5 and 6, a plug 31 slides into the top of the container. The plug is held in position by tab 35 engaging ring 41 between lugs 37 and stop 36. To remove the plug it must be rotated until stop 36 aligns with slot 41a the plug is then depressed thus deflecting the tab. The plug is then rotated until stop 36 aligns with stop 42, the plug then being slid out. Stop 42 keeps the tab 35 deflected preventing re-engagement with ring 41. In Fig. 7, the container top has a flange 48 with a groove 49, and a freely rotatable ring 52, having a groove 57 is mounted by means of a circlip below the flange. The cap 50 engages in the ring 52 by means of lugs 59 and tab 58. To remove the cap the ring 52 must be rotated so the grooves 57 line up with groove 49. Then the cap 50 must be further rotated so that the lug 59 lines up with the two grooves.

Abstract: 1359438 Marine propulsion A C SMITH 8 Aug 1972 [28 Sept 1971] 37005/72 Heading B7V [Also in Division F1] A pump used for marine propulsion comprises impeller vanes 17, Fig. 1, within the hollow crank-shaft 15 of the I.C. engine driving the pump. Water is taken in through an inlet 11 and expelled as a propulsive jet through a manuallydirectable nozzle 41 at the stern 9 of the boat. A thrust reverser 42 can be moved downwardly to reverse the direction of the jet. The supply of water to the jet can be blocked by a valve 35. A pipe 33 connected to the inlet 11 upstream of the valve 35 supplies water to the engine cooling water circulator. Exhaust gases and cooling water are discharged into the jet stream via an ejector passage 48 and carried away by the jet stream. A pivoted flap 79, Fig. 3, forms a non- return valve to prevent backflow of water into the exhaust manifold 47. When the valve 35 is closed, there is sufficient leakage through it to muffle exhaust noises. Accessories such as the cooling water circulator, an oil pump, a generator and a starter are connected to the shaft 15 via a shaft 21 and helical gearing. The shaft 15 may be forged in two semi-cylindrical halves, with portions of cam lobes 19 integrally attached and impeller vanes 17 forged or welded in position. Passages 61 for supplying oil to the shaft bearings may be formed in at least one of the mating faces of the two halves of the shaft. The two halves are welded together. The cam lobes 19 are connected to the pistons of a reciprocating engine or, as shown, to the generally triangular rotors 53 of a rotary engine. In the case of a rotary engine, each cam lobe may be replaced by a gear meshing with an internal gear on the rotor. The moment of inertia of the shaft 15 may be sufficient to permit the omission of a separate flywheel.
