According to a modification, the flywheel 21 is mounted between two similar spaced-apart discs secured to the shaft 4, the thickness of each disc being substantially half that of the wheel 20. In this construction, the magnetic coupling members may comprise a number of cylindrical magnets disposed around the periphery of the central flywheel. The masses of the flywheel portions secured to the shaft and freely mounted thereon are substantially equal. Instead of mounting the magnet members on the wheel which is freely rotatable on the shaft, they may be mounted on the wheel secured to the shaft, the freely mounted wheel being constructed of magnetic material.
Patent GB-840730-A (GB)
Title: Process for the polymerisation of olefines
IPC: C08F2/00
Filed: 1956-08-22
Abstract: Olefines are polymerized by a catalyst of the Ziegler type made by reducing a metal compound of sub-groups A of Group IV to VI, or Group VIII or manganese, with an organo-metallic compound, and then adding a further amount of the same or another organo-metallic compound.  It is stated that the metal salt e.g. titanium or zirconium tetrachloride is reduced to the trichloride, which may then be separated, taken up in a solvent and a further quantity of the same or another organo metallic compound added. The average molecular weight and its distribution or molecular range is controlled by the nature of the catalytic complex used, and especially by the aluminium alkyl compound viz: the average molecular weight is raised by increasing the proportion of this compound present, or by using e.g. an aluminium compound of higher alkyl content and fewer halogen atoms.  By using mixtures of such compounds e.g. aluminium tri-alkyl and di-ethyl aluminium mono-chloride the range of molecular weight is broadened. Examples and graphs are given showing the combination of molecular range and molecular weights by selecting the organo-metallic compound and the proportion used, the polymer produced is of a high molecular weight or comprises a mixture of two or more molecular weights.  For example, 2 g. of TiCl4 are mixed with 1.2 g. AlCl (C2H5)2, and 0.4 g., 0.8 g., 1.2 g. of AlCl2 (C2H5) then added to the product.  The catalyst complex is used to polymerize ethylene, and polymers of average molecular wt. 70,000, 130,000, 300,000 are formed respectively.ALSO:A low-pressure polymerizing catalyst of the Ziegler type is made by reducing a metal compound of sub groups A of Group IV to VI of the periodic classification, or of Group VIII or manganese, with an organo-metallic compound, and then adding a further amount of the same or another organo-metallic compound.  It is stated that the metal salt e.g. titanium or zirconium tetrachloride is reduced to the trichloride, which may be separated, suspended in a solvent, and then aluminium dichloro mono ethyl, or the monochloro-di-ethyl compound added thereto.  The average molecular weight of the polymer and the distribution or molecular range may be controlled by the nature of the catalytic complex used.  By increasing the proportion of aluminium alkyl compound present the average molecular weight is raised; a similar effect is obtained by using an aluminium compound of higher alkyl content i.e. aluminium trialkyl and further halogen groups.  By using mixtures of such compounds, tends to broaden the range of molecular weight of the polymer.  Examples and graphs are given showing the combination of these two effects.

Title: Improvements in or relating to mechanism for actuating changespeed gears
IPC: F16H63/46
Filed: 1926-10-18
Abstract: 283,997. Moran, H. Oct. 18, 1926. Controlling variable-speed goaring.-A lever 22 which is moved to operate selector bars 23, 24 is connected through one or more flexible members 54, 56 to a preselector 52, the actual change being effected by neutral and gear pedals, which also disconnect the main clutch of, say, a vehicle. In the arrangement shown in Figs. 2, 3, and 4, the up and down positions of the preselector crank 52 gives a pin 57 on the spring 56 a bias towards a notch 27 in a slider 20 on a notch 28 in a slider 21. The left and right positions of the crank 52 through spring 56 give the lever 22 a bias towards one or other selector bar 23, 24. There is a pivot at 58. The sliders 20, 21 are coupled to move oppositely by a lever 130. These sliders are brought to the neutral position shown in Fig. 2 to allow the selective motion to take place by depressing neutral pedal 4), which may disconnect the main clutch through lever 43. The ends 25, 26 of the sliders are bent over into the way of a pin 45 carried by the lever 40 and sliding in a slot therein. The pin 45 is biased upwards by a spring 50 so that when the pedal 40 alone is depressed, the pin 45 engages projecting end 25 and carries the slider 20 to the left into the neutral position shown in Fig. 2 with notches 27 28 opposite one another. The pin 57 and the lever 22 may then cross over. When gear lever 47 is depressed, the pin 45 is thrust downwards, engages projecting end 26 and brings the sliders to the gear position shown in Fig. 3 with the notches 2'7, 28 in their extreme positions. In another form, shown in Figs. 6 and 7, the lower end of spring 54 is jointed at 73 to a plate 61 with an E slot engaged by three pins 75, 76, 77 upon a disc 60. Left and right positions of the preselector 52 bias the disc 60, shaft 62, and gear lever 22 towards one or other of the selector bars 23, 24. The up and down positions of the crank 52 bias the plate 61 to its upper or lower position which determine which way the selector bar 23 &c. is to be thrust. When neutral pedal 71 is depressed, its lower arm 97 thrusts plate 61 to the left while through a lever 43 the main clutch is disconnected. The three pins 75 - - 77 are now in vertical slot 68 so that the plate 61 is free to move up or down, which has the effect of changing the direction in which the disc 60 is to be rocked. Depression of gear pedal 72 causes a pin 95 to be struck to disengage the main clutch again, while a link 70 is engaged, which pulls the plate 61 to the right, so that through the pins 75 - - 77 the disc 60 and with it gear lever 22 are turned through an angle, bringing in the selected gear. This gear selector may be adapted to control engine speed to facilitate the change. Specification 264,998 is referred to in this connection.

A motion picture camera having setting means for determining the picture frequency and automatic means for controlling the diaphragm aperture to correspond with said frequency, also has adjusting means provided for setting the frequency and diaphragm aperture independent of the first. In the camera shown, a series of lenses, e.g. lens 3, are arranged on a plate rotatable about an axis 4-4. Each lens is carried in a diaphragm-adjusting ring with a projection 5 which is spring-urged towards a maximum diaphragm aperture position but is arrested by a stop-arm 6 of a lever 7, the second arm of which is controlled by the arm 9 of a lever rotatable about a point 10 by vertical movement of a bar 12 which is spring-urged downward. The bar 12 is connected by means of a screw 21 resting on projections 22 to a movable plate 23 which is controlled by film feed adjustment means 31, so that adjustment of the film feed gives a corresponding adjustment of the diaphragm. The film speed is varied in steps by rotating a knob 32 which places one of a number of projections 36-38 of different lengths under the lug 22 which varies the vertical position of the plate 23 and also of the brake disc 40 of a pendulum governor 41 through a pin 39. The film speed (and diaphragm) may be altered quickly and continuously by rotating a lever 45 clockwise which rotates a cam 47 to move a rod 49 to the right against a spring, so that a cam edge 56 moves the plate 23 upwards. Similarly to alter only the diaphragm aperture the lever 43 is rotated which moves the bar 12 through a cam 46 and rod 48. Cam 47 is connected to lever 45 by a hollow shaft 44 carried on a shaft 42 to which are attached lever 43 and cam 46. The film feed is controlled by a button 64 and a ring 65. For one position of this ring still shots may be taken and the diaphragm aperture may be controlled by a projection 63 which engages slot 62 on a movable rod 59, the cam 60 of which controls rod 12 and the diaphragm aperture. Operation of release button 64 moves cam 66 out of engagement with rod 12. Means may be provided to mark the film at the parts run at a different speed, which marks may be detected by speed control means in a projector.
