Abstract: 1434972 Stopping IC engines P SCHMIDLI 25 July 1973 [25 July 1972 6 Oct 1972 19 Jan 1973] 35387/73 Heading F1K [Also in Division H2] In order to reduce atmospheric pollution the control system of an internal combustion engine in a vehicle is provided with means whereby the engine may be stopped when the vehicle is stationary and restarted when required without recourse to the normal starting system of the engine. The control system of an I.C. engine comprises the normal ignition-starting switch 3, ignition coil 4, starter motor 5, and a normally closed switch 7 responsive to a parameter of the engine when running. The system is further provided with a restarting switch 13, which may be associated with the vehicle clutch or accelerator pedal and a series of relays 19, 35, 51, 73, 87 and a time delay switch 63. The engine is normally started by closing the starter switch 3 thereby energizing the starter motor 5, the switch 7 opening to de-energize the starter motor 5 when the engine is running. When the vehicle is stationary depression of a push button 36 closes contacts 37, 39 in relay 35. Coil 25 of relay 19 is then energized from a line 17 connected to a battery 1 by the ignition switch 3 thus moving contact 23 from contact 22 to contact 24 to remove the energization of the ignition coil 4. The engine now stops and the switch 7 closes to complete the circuit of a hold-on coil 41 in relay 35 by way of contacts 81, 82 in relay 73. At the same time an indicating lamp 46 is energized to inform the vehicle driver that the push button may be released. Simultaneously by way of a conductor 48, relay 51 is energized to close contacts 56, 57. When it is required to restart the engine, pedal 11 is moved to close the switch 13 which causes energization of relay 73 by way of the time delay switch 63 and the switch 7. Operation of the contact 80 to contact 83 then de-energizes relay 35 and thereby de-energizing relay 19 which returns to normal thereby reestablishing the circuit to the ignition coil 4. Energization of relay 73 energizes relay 87 so as to energize the starter motor 5 thus restarting the I.C. engine, the switch 7 opening when the engine is running to stop the starter motor 5 and return the relay system to the normal state. The time delay switch 63 is provided to de-energize the system should the engine not be started within a predetermined time. The relay system may be replaced by solid state components and the switch 7 may be made responsive to any desired engine parameter.

Abstract: 522,438. Assembling can lids and bodies. BARLOW, R., RENOLD, P., HORNE, J. W., and GODDARD, E. Dec. 8, 1938, No. 35831. [Class 83 (iv)] Embossing.-In an apparatus for clenching covers to container bodies for food stuffs and, particularly oval or rectangular cans, in order to hold the covers in position during the heating of the contents prior to seaming, the bodies which have turned over edges, are mounted on a conveyer which moves between one or more pairs of resiliently mounted rolls for turning the edges of the cover about the edges of the body. The covers 7 are fed from a hopper 9 on to guides 6 by a reciprocating platform 10 in two stages, being marked by a stamp 13 at the first station. The blanks are held in the hopper by these jaws 12 carried by arms 15, the arms and stamp being operated by cams on a common shaft. The body 5 is moved along guides 1 and the cover along guides 6, 8 which are curved to assemble the parts, by dogs 4 on a chain conveyer 2 which moves the assembled parts through pairs of spring pressed rolls 22, 23, 24. The rolls 22 turn the edges of the cover downward and the rolls 23 turn it inwardly and upwardly beneath the edge of the body to complete the clenching. The rolls may be carried in spring-pressed slides 25 provided with adjustable screws 30 for adjusting the tension of the springs and with end stops 32, or may be carried by pivoted arms connected together by a common spring. The slides 25 are arranged normal to the tangent to the curved surface of the container so as to reduce friction. To avoid the tendency of the rolls to push a curved can away from the dogs 4 the rolls 23 are so disposed that the maximum width of the container does not pass beyond these rolls until the rolls 22 have completed their operation so that the rear of the container is held by the rolls 23 in engagement with the rolls 22. Similarly the control rolls 24 hold the rear of the container in engagement with the rolls 23 during the clenching operation of the rolls 23. The container may alternatively be positively held between a pair of grippers on the conveyer, so that a single pair or two pairs of rolls only need be used. When pivoted arms are used additional springs may be employed to exercise the spring tension on the rear half of the containers so as'to obtain an even clenching effect or the arms may be disposed at an acute angle with respect to the path of travel of the bodies. The rolls may be adjustable to suit cans of different sizes. A pair of rigidly mounted rolls may be mounted in front of the clenching rolls to reset the sides of a can body which may have been expanded by the pressure exerted when e.g. fish is pressed into the container.
