Patent GB-279551-A (GB)
Title: An improved lubrication indicator
IPC: F01M1/26
Filed: 1926-07-28
Abstract: 279,551. Smith, B. C. W. July 28, 1926. Stop-gear.-In an internal-combustion engine wherein an actuating member controlled by the pressure in the lubricating system operates contact elements forming part of an electric circuit controlling the ignition circuit of the engine, a mechanical time-limit switch is provided in the controlling circuit so as to allow the engine to be started before the actuating member comes into action. 'The pressure in the lubricating system acts through a connection 3 on a piston 6 in a cylinder 2. In its highest position, the piston abuts' against an annular disc 4. The piston rod 7 passes through an adjustable guide 8 in a disc 9 threaded into the top of the cylinder, and a spring 10 is arranged between the piston and the guide. The upper end of the rod has a recess 16 engaged by the forked end of an arm 17 pivoted on a pillar 18, the arm being provided with projections 19. A pillar 21 has a pin 23 which supports the forked end of a contact member 24 which carries a cross pin 25. A pair of springs 20 are connected between the members 19, 25, so as to provide for a quick rooking of the member 24 from the position shown in Fig. 1, where it contacts with an insulated member 26 connected to a circuit wire 29, to a position where it rests against a stop 22 carried by the pillar 21. The cylinder 2 is earthed by a wire 30, and an air vent 31 is provided between the discs 4, 9. The time-limit switch 32 comprises spring-governed clockwork mechanism wherein an arm 39 is normally pressed against a rocking lever 40, Fig. 5, so as to press an insulated spring contact 37, connected to the wire 29, against an insulated contact 38, connected by a wire 41 to a relay coil 42. By turning a knob 25, on the spindle of which is an indicator hand 36, the mechanism can be wound so as to withdraw the arm 39 from the lever 40 so as to break the contacts 37, 38 and temporarily render the controlling circuit inoperative. When, however, under the influence of the clockwork, the arm 39 returns and presses against the lever 40, the contact 37 is again pressed against the contact 38. In such position, if the oil pressure is too low, so that the member 24 is in contact with the member 26, current flows from the battery 43 through the wires 41, 29, 30 and through the relay coil 42, which latter is thus energized, attracting the armature 47 and opening the contacts 48, thus breaking the main ignition circuit 49 and stopping the engine. As applied to a magneto ignition circuit, the wire 41 is connected to the primary terminal of the magneto.

Title: Treatment of gaseous effluent
IPC: F01N3/30
Filed: 1972-04-24
Abstract: 1384342 Treating exhaust gas QUESTOR CORP 24 April 1972 [13 April 1972] 19002/72 Heading F1B A process for minimizing emission of noxious substances from an effluent containing carbon monoxide, hydrocarbons and oxides of nitrogen, comprises the steps of a) oxidizing a portion of the total oxidizable components in the effluent by introducing an oxygen-containing gas into said effluent without oxidizing completely the carbon monoxide, b) exposing the effluent to an environment to chemically reduce a substantial part of the oxides of nitrogen and c) exposing the effluent to an oxygen-containing gas to oxidize oxidizable components remaining in the effluent. An apparatus for carrying out the method when dealing with the exhaust gas from an I.C. engine comprises a manifold reactor 13 having gas passages 15, 16 and 17 which are bolted to the cylinder head 12. An engine driven air pump 9 supplies air through four tubes 21, 22, 23, 24 each of which projects into an exhaust port. The amount of air injected is sufficient to oxidize some but not all the carbon monoxide in the effluent, leaving sufficient to react with the oxides of nitrogen in the second stage of treatment, thereby reducing the oxides to nitrogen. The carburation of the engine is adjusted to provide a rich mixture e.g. 10À1 to 1 by weight, so that the concentration of carbon monoxide in the exhaust gas is between 0À1 and 15% and is preferably between 7 and 10%. The concentration of oxides of nitrogen should be less than 700 p.p.m. and preferably less than 300 p.p.m. In this first stage of treatment the carbon monoxide is reduced to about  of its original level and the oxides of nitrogen to about ¥ of their original level. The partly-oxidized effluent which should contain less than 0À3% oxygen leaves the reactor 13 by a pipe 19 and enters a device 18 which consists of a housing 27 containing catalystsupporting baffles 31. As the effluent flows through the baffles the reaction between the oxides of nitrogen and the carbon monoxide occurs, and results in the carbon monoxide concentration being reduced to about <SP>2</SP>/ 3  of its level at entry to the second stage, and the oxides of nitrogen being reduced to about 7% of their concentration at entry to the second stage. The catalyst is copper which is present as a coating on the baffles 31 and the temperature in the device is about 1800F, the oxidation in the first stage having raised the temperature of the exhaust gases by about 700F. Downstream of the baffles 31 is a tube 26 which is connected to the pump 9 and which feeds air into the device to effect oxidation of the remaining oxidizable components of the gases. The amount of air is 1 to 1¢ times the stoichiometric amount required. After passing through the third stage, the gases have the following composition CO, 32 p.p.m: NO, 12 p.p.m: HC, nil: CO 2 , 14.5%: O 2 , 4.1%: H 2 , 700 p.p.m: and N2, 81.5%. The temperature at the tail pipe 30 was 1587F. The catalyst may be a metal or metal oxide or an alloy or mixture of Groups 1B and IV to VIII of the Periodic Table.

The edges 9 are formed on porcelain members 8 each connected to an associated jaw 11 pivotable about a shaft 10 and carrying an arm 12. Springs 14 act on the arms 12 to bias the edges 9 towards each other. The ends of the band 5 are clamped between plates 17 and shaped-heads 16<SP>1</SP> of screws 16, the heads 16<SP>1</SP> being secured to an electrically non-conductive block 15. Leads 20, 20<SP>1</SP> for supplying current to the band 5 are carried between nuts 18, 19 on the screws 16 and extend to slip rings (not shown) rotatable with the cylinder 3 and which are energized by brushes (not shown). The block 15 is provided with a screw 21 passing through a support 22 on the end plate of the cylinder 3. The band 5 is tensioned when it is installed by moving the block 15 radially inwardly by tightening a nut 23. The gap between the edges 9 is such that, even when the band is elongated to a maximum, short circuiting between the parts of the band passing over the edges 9 is avoided. The radiallyoutwardly directed side of the band 5, at least, is coated with polytetrafluoroethylene.
