Title: Operating an internal combustion engine with low nitrogen-oxide emissions
Inventor: FRANKLE GERHARD
IPC: F01N13/02
Filed: 1997-07-04
Abstract: Operating an internal combustion engine 1 with low nitrogen-oxide emissions by having two modes of operation. A first mode of operation, in which an early start of fuel injection is set, has high nitrogen-oxide emissions and low fuel consumption, and a nitrogen-oxide reducing agent 5 is added to the stream of exhaust gases upstream of a nitrogen-oxide-reducing catalytic converter 4. A second mode of operation, in which a late start of fuel injection is set, has low nitrogen-oxide emissions and high fuel consumption. A sensor 18 measures the temperature of the catalytic converter 4, and the engine is operated in the low emission second mode if the temperature of the catalytic converter lies outside a prescribable temperature range for effective catalytic nitrogen-oxide reduction. The emission levels are monitored 20 at the output of the catalyser, and the start time of the fuel injection can be adjusted to keep these at a specified level. The input levels of nitrogen-oxide can also be monitored 19 to check that the catalyser is functioning correctly.
Patent GB-2332087-A (GB)
Title: Apparatus and method relating to ion beams and gaseous plasma
Inventor: AITKEN DEREK
IPC: H01J27/14
Filed: 1997-12-02
Abstract: An ion source for the production of an ion beam or series of ion beams having a high uniformity is based on the concept of extracting an ion beam through a plurality of virtual magnetic poles provided for the purpose of containing a plasma. A virtual pole is an apparent N or S pole cusp position, when there is not physically a magnet at this position. An array of virtual poles 24 (Figure 6) is formed by aligning magnets 13 with like poles 28 facing each other forming pairs of virtual poles 24 along each mid position line 27 between the magnets. The field around the virtual poles 24 has four cusps, namely: two cusps 26 of the virtual poles 24, lying on the mid line 27 which is the axis of the virtual poles 24; and two cusps 25 at the real poles 28 of the magnets 13. In a practical construction (Figure 8A) the magnets 13 are contained within a series of tubes 41 each having triangular external section, and forming in combination an outlet electrode 31 shaped for the requirements of ion extraction through extraction slots 36. The magnets 13 are cooled by flowing coolant 32. An extraction electric field is provided by external electrodes (not shown) and an ion beam 33 is formed. Either permanent magnets or electromagnets may be used. Other aspects of the invention relate to the tensioning of parallel elongate ion extraction components, to rotation of both the ion source and a sample support to scan the beam(s) and achieve uniform ion implantation of a sample held on the support, and to electrostatically repelling positive ions and primary electrons back into the plasma while secondary electrons are removed.

Title: Puller-thruster downhole tool
Inventor: MOORE NORMAN BRUCE
IPC: E21B23/08
Filed: 1996-08-22
Abstract: A method and apparatus for propelling a tool having a body within a passage. The tool includes a gripper including at least a gripper portion which can assume a first position that engages an inner surface of the passage and limits relative movement of the gripper portion relative to the inner surface. The gripper portion can also assume a second position that permits substantially free relative movement between the gripper portion and the inner surface of the passage. The tool includes a propulsion assembly for selectively continuously moving the body of the tool with respect to the gripper portion while the gripper portion is in the first position. This allows the tool to move different types of equipment within the passage. For example, the tool advantageously may be used in drilling processes to provide continuous force to a drill bit. This enables the drilling of extended horizontal boreholes. Other preferred uses for the tool include well completion, logging, retrieval, pipeline service, and communication line activities.

Title: Brake assembly for a powered rotary tool e.g. a lawnmower or a hedge trimmer
Inventor: BOWDEN MICHAEL
IPC: F16D59/02
Filed: 1998-04-09
Abstract: A powered rotary tool e.g.a lawnmower or a hedge trimmer comprises a transmission including a rotary drive shaft 3 and a rotary driven shaft 5, and a brake assembly which includes a first brake element 7c, which constitutes part of the transmission, and a second brake element 11. The brake element 7c is movable relative to a drive element 7a circumferentially and axially of the driven shaft 5 by means of spring and a camming arrangement (9a, 9b, 10, Figure 3). When drive to the drive shaft 3 is removed, overrun of the drive element 7a causes the brake element 7c to move into contact with the second brake element 11. The transmission may include a belt or intermeshing gears, and various camming arrangements are disclosed including, in an alternative embodiment, an arrangement in which intermeshing helical gears 24, 28 effect axial movement of gear 28 (first brake element) towards and away from the second brake element 29.

Title: Cooking appliances
Inventor: FLOYD ARTHUR
IPC: F24C3/08
Filed: 1999-06-19
Abstract: A cooking appliance is disclosed in which an oven cavity <B>224</B> is heated by means of burning gas and wherein the oven has limited flue area. A fan <B>209</B> is included in the appliance which draws air into an enclosed chamber <B>212</B>. The excess air pressure in the chamber provides a flow of air through a duct <B>218</B> and around a gas burner <B>208</B> in the oven cavity. The fan causes a sufficient air flow to remove combustion products from the burner when the oven is cool. However, the appliance is configured to allow established convection currents to be sufficient without the assistance of the fan, when the oven is warm.

The conveyer is moved into and out of the upper opening 8 to allow the flap 3 to close. During a delivery the charge material, which may be of fragile green pellets, falls only a short distance into shaft 18 and forms a conical heap, the basket being in the raised position so that the bell-bottom closes the bottom of the shaft. When the shaft is filled the basket is lowered allowing the charge to run into the basket. The basket is lowered, as the conveyer delivers further charge, until it rests on stops 12. When the lower bell 4 is lowered the bell-bottom moves with it allowing the charge to run out of the basket into the furnace. The lifting device 11 then raises the bell-bottom 7 and the basket and the cycle is repeated.
