Title: An improved time measuring apparatus driven by a synchronous motor and an auxiliary movement
IPC: G04C15/00
Filed: 1936-12-14
Abstract: 466,746. Time switches. LANDIS & GYR AKT.-GES. Dec. 14, 1936, No. 34263. Convention date, Dec. 18, 1935. [Class 38 (v)] [Also in Group XVIII] Time-measuring apparatus in which a day disc or dial plate 11 is driven by a synchronous motor 5 and an auxiliary movement 7 in reserve, particularly for driving time switches, is characterized in that the dial plate 11 carries switch-controlling pins 9 and 10 which actuate only a controlling device 18, 19, 20 whereby the motor 5 is caused to actuate the time switch 16 from time to time. An overrunning gear 1 is provided so that normally the dial 11 is driven by synchronous motor 5 through train 2, 3, 4, 1 whereas during current failure, the reserve movement 7 drives plate 11 through train 6, 1. The spring of movement 7 is wound up by motor 5 through train 8. A train 2, 14 drives one sun wheel 13 of a differential gear 12, of which the planet wheel 27 is carried on shaft 15 together with switch 16 and two cams 25, 26 the effective points of which are 180‹ apart. The other sun wheel 17 is rigid with detent wheels 18, 19 freely rotatable on shaft 15. A pawl 21, normally held up by latch 23, coacts with wheel 18 and has an arm coacting with cam 25. Similarly a pawl 22 and its arm, controlled by latch 24, coacts with wheel 19 and cam 26. Normally, as shown, motor 5 rotates wheels 13, 27, 17 in the directions shown, with shaft 15 stationary. When pin 9 on dial plate 11 knocks aside the latch 23, pawl 21 drops and holds wheel 18 so that shaft 15 is now rotated and the switch 16 is rotated to the " off " position. After a half revolution, cam-25 raises pawl 21, which is relatched by arm 23 and shaft 15 is again stationary. Later, pin 10 removes latch 24, pawl 22 arrests wheel 19, shaft 15 is again rotated and switch 16 is rotated to the " on " position. As before, after a half revolution cam 26 causes the relatching of pawl 22 and shaft 15 is once more immobile. If current fails, reserve movement 7 drives the plate 11, pins 9 and 10 release pawls 21 and 22 to hold the wheels 18, 19 but no movement of shaft 15 or switch 16 can take place until current is again supplied to motor 5.
Patent GB-1045967-A (GB)
Title: An ignition system for internal combustion engines
IPC: F02P7/03
Filed: 1963-08-29
Abstract: 1,045,967. Ignition systems. PAL-MAGNETON, NARODNI PODNIK. Aug. 29, 1963 [Sept. 4, 1962], No. 34280/63. Heading F1B. An ignition device for multi-cylinder internalcombustion engines comprises at least two switching circuits each of the circuits including at least one step up transformer one circuit being coupled to the spark plugs associated with every other cylinder according to the firing order and the other circuit being coupled to the remaining spark plugs, the circuits being coupled to each other so that when one of the circuits is rendered conducting through an impulse from a timing transmitter the other circuit is rendered non-conducting and vice versa whereby when one or the other of the switching circuits stops conducting the variation of current in the primary winding of the associated step up transformer induces a voltage in the secondary winding which is fed to the appropriate spark plugs. In Fig. 1 on opening of the contacts of the contact breaker 16 the transistor 11 cuts off and the current in the primary winding 18 is cut off. This results in a rapid collapse of the magnetic field which induces a voltage in the secondary winding 20. At the same time however, the transistor 10 starts conducting. After reclosing of the contacts of the contact breaker 16 the transistor 10 stops conducting. Fig. 2 shows a modification in which alternating current is generated by a transistor associated with a transformer 30 and with a disc 38 comprising alternate metallic and non-metallic sections. This current rectified by a rectifier 36 controls the apparatus 37. In another modification there are four ignition transformers supplying six sparking plugs. In a further modification a disc similar to the disc 38 is associated with a coil instead of a transformer. The circuit supplies eight sparking plugs. Timing may be controlled by induction manifold vacuum and by a centrifugal mechanism.
