Title: Automotive internal combustion engine having an exhaust cleaning system
IPC: F02P5/155
Filed: 1974-03-08
Abstract: 1444473 Purifying IC engine exhaust gas NISSAN MOTOR CO Ltd 8 March 1974 [13 March 1973] 10621/74 Headings F1B and F1H An internal combustion engine comprises an afterburner 36 connected to the exhaust pipe 14 of the engine, an exhaust gas recirculation passageway 74 connecting the exhaust pipe to an air inlet, a valve 76 in the passageway, and sensing means 80 sensing the temperature of the afterburner 36, the arrangement being such that when the temperature of the afterburner is below a predetermined level, the valve 76 is opened with or without some delay letting exhaust gases into the air inlet to heat the air drawn into the engine to cause rapid increase in the temperature of the exhaust gases and thereby enable the afterburner to reach its activation temperature rapidly. A temperature sensor 70 in the water jacket 22 of the engine controls a switch 72 and consequently a solenoid valve 58. When the temperature of the water is below a predetermined level, the solenoid valve opens to connect the inlet manifold 28 to a chamber 62 of a throttle control unit with the result that the throttle 18 is moved to a position of fast idle until the water temperature reaches the predetermined level. Two sets of contact breakers 48, 48' provide normal spark advance and retarded spark advance respectively, the sets being connected in parallel, with the retarded set 48' having its circuit completed through either a relay 86 or a time relay 54. The relay 86 is closed whenever the afterburner temperature is lower than its predetermined value and the time relay 54 is closed whenever the selfholding relay 56 is energized, i.e. when energizing the starter motor. Hence, on cold starting the throttle 18 will be moved to fast idle and the ignition will be retarded in compensation.

Filed: 1952-04-28
Abstract: 703,045. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 28, 1952 [May 26, 1951], No. 10622/52. Class 38(3) [Also in Group XXXV] When a predominantly resistive shunt 30 is connected across at least part of the field windings 23 of a D.C. motor M fed from a source having a substantial ripple, a mutual-inductor divider 31 is arranged to divide the ripple between the shunt and the field winding. Such an arrangement improves the operation of a series wound traction motor M supplied through rectifiers 11, 12 carried on the vehicle, in a system such as forms the subject of Specification 682,610 in which the D.C. is arranged to have a substantial ripple to reduce harmonies in the trolley wire 3 which give rise to telephone interference. As the motor is accelerated, taps 8, 9 on supply transformer 6 are moved from low to high voltage positions by a controller, switch FS1 being closed and switches FS2 and FS3 opened so that no D.C. flows through shunt 30 and the ripple divides through the halves of the mutual inductance 31 which thereby has negligible effective inductance. The controller then closes switch FS2 and opens switch FS1 so that shunt 30 is connected in parallel. with field winding 23, the D.C. component dividing in the ratio of the resistances of the shunt and winding, and the ripple dividing in inverse ratio to the inductance values of the two parts of inductor 31. To improve the motor performance the ratios of division of D.C. component and of ripple may be made the same, and may be kept the same when, by closing switch FS3 and opening switch FS2 the resistance of the shunt 30 is reduced and the number of turns of that part of the inductor supplying the shunt is also reduced.

Abstract: 108,202. Wade, H., (Universal Winding Co.). July 27, 1916. Winding-machines.-The object is to provide a traverse mechanism capable of minutely accurate adjustment for different lengths of traverse and for the position of the traverse with regard to the winding-spindle, and to ensure a constant speed of movement of the guide throughout the full extent of the traverse, the invention being particularly intended for use in machines for winding electrical coils of the kind described in Specification 91/13. The sliding frame K carrying the hinged guide carrier K<1> is connected by the traverse rod R to a slide S, which moves in a straight guide-way P, which can be adjusted towards and from the centre of motion m of the oscillating lever M by means of a hand-operated screw X, Y, the scale upon the frame H<2> indicating the extent of the traverse which is given to the rod, and the slide S moving in the slot m<4> of the oscillating lever m with the adjustment of the guide-way. The oscillating lever M is operated by the cam C by means of a stud o<2>, which engages both with the cam and the lever and is also constrained to move in a straight line by being carried by an horizontal slide on the side of the fulcrum m opposite to that on which the slide S and guideway P are situated. The relative movements of the stud o<2> and slide S are thus the same throughout the winding operation. In order to provide a small adjustment of the frame K relative to the winding-spindle, the enlarged extremity T of the traverse rod R is connected to the slotted frame K by means of a stud of which the part which engages with the slot k<3> is eccentric to the main portion, so that by rotating the stud the position of the frame K is adjusted, the amount of the adjustment being indicated on a notched or graduated arc. The machine is shown provided with a second traverse cam C' so that a layer of yarn or insulating material may be wound simultaneously with the wire &c. wound by the traverse cam C. The driving-connexions between the spindle and the cams C, C' are the same as those described in Specification 12167/13.
