Title: Exhaust gas treating system for internal combustion engine
IPC: F01N3/38
Filed: 1972-02-04
Abstract: 1346154 Purifying I C engine exhaust gas NISSAN MOTOR CO Ltd 4 Feb 1972 [17 Aug 1971] 5404/72 Heading F1B An I. C. engine exhaust gas purifying system comprises a catalytic reactor 11 disposed in exhaust pipe 10 and a burner unit 14 upstream of reactor 11 for controlling the temperature of the catalyst 12. Unit 14 includes a burner chamber 15 which can be supplied with an airfuel mixture through passage 17 and communicating with exhaust pipe 10 through duct 16. Passage 17 includes an air pump 25 drivable through an electromagnetic clutch 26 and a Venturi 19 into which fuel may be drawn via nozzle 20 from float chamber 21. A shut-off valve 24 is associated with nozzle 20. The catalytic reactor 11 contains two thermostatic switches 33, 34 incorporated into a control circuit Fig.2 (not shown). To start the engine an ignition switch (32) is closed and providing the catalyst temperature is below a lower limit, e. g. 500‹ C, switch 33 also closes to cause fuel valve 24 to open, and energization of burner igniter 29 and clutch 26. Thus a fuel-air mixture is supplied to burner chamber 15 through passage 17 together with additional air from by-pass 28, the combustion gases flowing through duct 16 to heat catalyst 12. When the temperature of the latter reaches 500‹ C switch 33 opens to shut-down burner unit 14. At about 650‹ C switch 34 closes to energize only clutch 26. Thus pump 25 directs a stream of cooling air through chamber 15 and duct 16 to prevent overheating of catalyst 12. The latter is therefore maintained between about 500 and 650‹C throughout the engine operating range. A modified control circuit Fig.4 (not shown) includes a timing device (44), logic circuit (46) and an acceleration sensor (43) which cause operation of burner unit 14 for a predetermined time during acceleration.

Abstract: 616,288. Automatic voltage regulation. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 22, 1946, No. 5544. Convention date, March 21, 1945.. [Class 38 (iv)] [Also in Group XXXVI] In a supply arrangement comprising a voltage transformer 3 in series with a resistance 4 in a circuit fed from a capacitative voltage divider 1, 2 non-desirable oscillations are damped out and voltage regulation effected by a compensating transformer 5 with one winding in parallel with the resistance. As shown, the resistance 4 is in series with the primary winding of the voltage transformer 3 and in parallel with the primary winding of the compensating transformer 5, the secondary windings of the two transformers being connected in series across a load 6, 7, e.g. relays or instruments. Alternatively the primary windings of the two transformers may be connected in series and the resistance put in parallel with the secondary winding of the compensating transformer. The transformers are generally of the same K.V.A. rating, but the voltage of the compensating transformer is about half that of the other. The voltage transformer is connected across one of a large number of series connected condensers, of which only two are shown.

Title: Improvements in and relating to dynamo electric machines
IPC: H02K23/20
Filed: 1916-04-17
Abstract: 150,357. British Thomson - Houston Co., (General Electric Co.). April 17, 1916. Exciting; cores.-A dynamo-electric machine, more particularly adapted for use on an automobile as an engine-starting motor and as a generator of practically constant electromotive force for lighting and battery-charging, is provided with three field-magnet windings 21, 26, 27. The winding 21 is distributed in slots in two opposite quadrants of the field structure 20 and is arranged with its axis at an angle of forty-five electrical degrees to that of the armature winding 22; the winding 21 is connected in series with the armature winding. The winding 26 is a magnetizing- winding and has its axis at right-angles to that of the armature winding; the winding 27 acts in opposition to the winding 26 and is connected between an auxiliary brush 28 and the nearer main brush 24. The winding 26 is either a pure shunt winding, as shown in Fig. 8, or it may be connected between the brushes 28, 34. When the machine operates as a motor, the effect of the armature current predominates and the winding 21 gives the starting characteristics of a compensated series motor, the effect of the windings 26, 27 being negligible. When operating as a generator, the demagnetizing effect of the winding 27 increases as the speed rises so that the voltage is kept fairly constant. The winding 27 embraces only a portion of the polar arc occupied by the winding 26, the flux threading the portions 30 remaining substantially constant. To improve commutation, wide slots 25 are provided for the reception of the coils 26 etc.; the slots 25 are preferably closed by non-magnetic wedges 31, while the other slots in the field magnet are closed by magnetic wedges 32.

Other examples are concerned with coagulating mixtures of a natural rubber latex and a barytes slurry, a 30 per cent GR-S Type I latex and a soapstone slurry, a rubber latex and a limestone slurry.  Road construction compositions are made by mixing the powders with powdered or liquid asphalt, or by first mixing the powder with an asphalt solvent such as fuel oil, diesel oil or light lubricating oil and incorporating this mixture into a mixture of asphalt and crushed limestone, slate, slag, gravel or the like. Specification 767,682 is referred to.

Title: Improvements in or relating to endless conveyors for automatically delivering carriers for work-pieces at pre-selectable delivery points
IPC: B65G47/48
Filed: 1963-02-18
Abstract: 959,943. Endless conveyers. G. M. PFAFF A.G. Feb. 18, 1963 [Feb. 19,1962], No. 6389/63. Heading B8A. An endless conveyer 1 for workpiece carriers 7 each having a hook-shaped suspension member 7a received on a conveyer member 4 by a supporting member 8 and which are deposited automatically on receiving bars 29 at predetermined delivery stations is characterized by a V-shaped supporting member 8 mounted on a spindle 6 and co-operating with stationary guide rails 30 at the delivery stations. A conventional selector device 31 with contact member 32 cooperates with switches 33 actuating a push-rod 39 of an electromagnet 38 to push a release lever 34 from its normal spring-retained (dotted) position into the path of a control rod 18 where it is retained by a spring latch 40. This causes the rod 18 to rotate against a spring 20 and tilt a control disc 9 attached to the spindle 6 through a driver 22 engaging a pin 24 on the control disc, a pin 26 sliding in a slot 28 in a wall 5 limiting the angle of tilt. Sideways movement of the conveyer member 4 is limited by a roller 47 engaging a guide 46. The hook 7a slides down the arm of the V and engages a guide rail 30 at the end of which it drops on to a receiving bar 29. When the conveyer member 4 has moved sufficiently for a roller 15 on the rod 18 to clear the release lever 34 the roller 15 under the returning action of the spring 20 on the rod 18 forces the latch 40 to release the lever 34 which is returned to its inoperative position by a spring 37. At the same time an aim 12 attached to the rod 18 acts on a rib 10 on the control disc 9 to return the support 8 to its initial position where it is held by the arm 12 and a corresponding arm 11 on the symmetrically arranged rod 17.
