Title: Improvements in toy vehicles and tracks
IPC: A63H18/16
Filed: 1957-08-12
Abstract: 876,054. Toy vehicles and tracks. HESLOP, J. D. Oct. 23, 1958 [Aug. 12, 1957], No. 25429/57. Classes 132(2) and 132(3). A track for use with electrically driven toy vehicles has spaced strips of electrically conducting material for supplying current to the driving motors of the vehicles and includes a guide strip of magnetic material for magnetically controlling steering gear provided on the vehicles. A track section consists of a base 10 of insulating material on which are sprayed magnetic strips 12 of iron dust admixed with an adhesive. The base is then sprayed with a layer 13 of insulating paint, and a series of copper strips 14 are sprayed on the layer 13. The sides of the base are bent over to encircle bus-bars 15, 15A formed with projecting pins 16 for engaging in sockets 36 of the bus-bars of adjoining sections of the track. Alternate copper strips 14 are connected to the busbar 15 and the remaining copper strips are connected to the other bus bar 15A. A toy car is driven by an electric motor 24 and is steerable by castoring wheels 22 controlled by a magnet 28 which follows the iron strip 12 between a pair of copper strips 14; contact strips 25 on the motor engage the strips 14. A fixed magnet 29 of the same polarity as the magnet 28 repels the front magnet of any other car which is following too closely and causes the following car to steer away. The deflected car continues to travel by inertia until its steering magnet coacts with another iron strip 12 and guides its contact strips 25 on to the associated pair of copper strips 14. The fixed magnet 29 may be placed at the front of the car and the pivoted magnet 28 at the rear. On curved sections of the track the iron stripsmay deviate from the copper strips towards the inside of the bend so causing cars approaching the bend at its outer side to move on to copper strips situated nearer the inside of the. bend. The copper strips may extend transversely to the length of the track, the contact strips on the cars being appropriately staggered so that they make contact with alternate copper strips as the car follows a longitudinal iron strip. Banking, flyovers and cross-overs may be provided. By placing a number of the vehicles on the track, the user may simulate conditions on motor racing tracks. According to the Provisional Specification, each vehicle has a reciprocating electric motor and the steering is controlled by a pivoted magnet co-operating with an associated pulse emitter.

Title: Ignition systems for internal combustion engines

Filed: 1973-05-30
Abstract: 1412711 Ignition systems ROBERT BOSCH GmbH 30 May 1973 [31 May 1972] 25802/73 Addition to 1027532 Heading F1B An ignition system for a spark ignition internal combustion engine has a first circuit with a primary winding of an ignition transformer and with a storage capacitor 3 for storing electrical energy, a second circuit with an induction winding 1 for storing magnetic energy and control means in each of these two circuits whereby at the instant of ignition the storage capacitor 3 and the induction winding 1 release the energy stored therein to the transformer secondary circuit 9, the control means of the second circuit comprising a contact breaker switch 8 which is operable to control an electronic switch 4 of the control means of the first circuit, the contact breaker switch being connected in parallel with an ignition capacitor 7 when an operating switch 22 is closed a voltage is applied to the input 24, 25 of the voltage converter 20 whereupon a high oscillating voltage is produced in the charging winding 11. This high voltage is converted to a pulsating direct current by the diode 12 and the capacitor 3 is charged. With the contact breaker switch 8 closed the source of direct current 21 supplies current to the winding 1. If the contact breaker switch 8 is opened at the instant of ignition the emitter collector path 32, 34 of the transistor 31 becomes conductive. Thus the control capacitor 36 previously charged by the source of direct current 21 can now discharge by way of the resistor 38, the resistor 33, the emitter collector path 32, 34 and the control resistor 35. A voltage thus appears across the resistor 38 and positively biases the control electrode 37 of the thyristor 5 relative to the cathode 16 to an extent where the switching path 17-16 of the thyristor becomes conductive. Thus the storage capacitor 3 can discharge by way of the switching path 17-16 and the primary winding I of the ignition transformer to produce a spark at the plug 10. At the same time the primary winding circuit is interrupted by the opening of the contact breaker switch 8 whereby a voltage is induced in the secondary winding 9 so that a train of sparks follows the ignition spark produced by the discharge of the condenser. In a modification (not shown) a permanent magnet driven by the engine is associated with the primary winding of the ignition transformer and in a further modification the charging voltage for the capacitor 3 is produced in a charging winding associated with this permanent magnet. Other modifications are described. The secondary winding 9 may be associated with a distributor and a plurality of sparking plugs.
