Title: Improvements in or relating to ignition system of internal combustion engines
IPC: F02P3/01
Filed: 1957-02-05
Abstract: 833,011. Ignition systems. WESELCO Ltd. Feb. 5, 1957 [Oct. 5, 1956; Jan. 15, 1957], No. 3912/57. Class 7(4) An ignition system for an internal combustion engine comprises a transistor, means for coupling an output circuit of the transistor to an input circuit thereof, whereby the arrangement is adapted to produce high frequency oscillations, means for raising the voltage of the high frequency oscillations to a level appropriate to operate a sparking plug for the engine and mechanically operated contacts associated with the arrangement for controlling the supply of current to the plug the contacts being included in a circuit in which substantially no direct current is flowing. As shown, a PNP junction transistor 1 connected in circuit with coils 2, 3 produces high frequency oscillations. A booster coil 4 coupled by means of a magnetic circuit with the coil 2 supplies high frequency oscillations to a distributer arm 5. When the contact breaker contacts 7, 8 are closed the coil 2 is short circuited and the oscillations are interrupted. A separate coil in series with the coil 2 may be used to supply the oscillations to the coil 4. In a modified oscillator the coil 3 is coupled to a coil in the emitter lead. Several ways of controlling the system by a contact breaker are described. A resistance may be used so that the oscillations are not strong enough to produce a spark across the plug until the contact breaker is operated. The movable contact of the contact breaker may be connected to the emitter or base circuit of the transistor. Fig. 5 shows a modification in which a coil 14 is associated with the contact breaker. Until the contacts 7, 8 are moved apart the oscillations are not sufficient to produce a spark across the plug. Transistors of the NPN type may be used instead of the PNP type.

Title: Photographic shutter
IPC: G03B7/083
Filed: 1953-02-13
Abstract: 748,406. Photo-electric exposure control. DURST SOC. PER AZIONI FABBRICA MACCHINE ED APPARECCHI FOTOTECNICI, DURST, J. and DURST, G. Feb. 13, 1953 [Feb. 15, 1952, July 9, 1952], No. 4174/53. Class 40 (3). [Also in Group XX] The speed of operation of a camera shutter is controlled by a pneumatic device the flow of air in which is controlled by a shutter positioned by the moving element of a photo-electric exposure meter. As shown, the pointer c of a moving coil galvanometer fed by the photoelectric cell carries a shutter b which is positioned over a wedge-shaped aperture d in the top of a cylinder obturating more or less of the aperture according to light intensity. Inside the cylinder is a piston f the connecting rod g of which is coupled to a shutter-operating member h. To set the shutter which consists of leaves n, o, a lever m is pressed which moves the leaves to the position shown where they are held by pawls p and q and moves the piston f to the top of the cylinder loading a piston restoring spring i, the piston being held in this position by the shutter release l. When this release lever is pressed spring i moves piston f creating a partial vacuum in the cylinder and releasing in turn pawls p and q. The period between the release of the two leaves depends on the speed of movement of the piston and this in turn is controlled by the extent of the obturation of the apertures by the member b. This member is flexible and is drawn against the apertures by air pressure. Instead of a single aperture a number of separate holes arranged to be successively closed may be provided. An arrangement is also described (Fig. 6, not shown), in which the invention is applied to the control of everset shutter.
