Title: Operating a spark-ignition internal combustion engine with intake stroke or compression stroke injection
Inventor: BIEMELT ANDREAS
IPC: F02B75/12
Filed: 1997-10-27
Abstract: A spark-ignition internal combustion engines with one injector 4 per cylinder 2 for internal mixture formation can be operated with fuel injection in the intake stroke of the piston in the case of full load or high partial load, and with compression-stroke injection in the case of medium or low partial load. However, the compression-stroke injection is, in some cases, possible only to a limited degree because of the formation of deposits in the combustion space during compression-stroke injection, which adversely affect the mixture formation and combustion conditions. A control system 6 is therefore provided which ensures that while the internal combustion engine is operating in the compression-stroke injection mode, the injection is switched over as a function of time or of at least one monitored operating parameter, and independently of the instantaneous load request, to intake-stroke injection with simultaneous reduction of the intake air quantity. The injection is then switched back into the compression-stroke injection mode after a specific burning-clean interval has elapsed. The monitored operating parameter which causes the injection to be switched can be related to the smooth running of the engine, e.g. the rotation time of the flywheel, or can be derived from a test voltage applied across the spark plugs 5.

Patent GB-2323605-A (GB)
Title: Propane recovery process
Inventor: SORENSEN JAMES N
IPC: B01D53/14
Filed: 1996-11-01
Abstract: Increased recovery of propane, butane and other heavier components found in a natural gas stream is achieved by installing an absorber upstream from an expander and a separator. The separator is downstream from the expander and returns the liquid stream generated by the separator back to the absorber. Additionally, the recovery of propane, butane and other heavier components is enhanced by combining the upper gas stream from a distillation column with the upper gas stream from the absorber prior to injecting this combination into the separator. The upper gas stream removed from the separator is then subsequently processed for the recovery of a predominantely methane and ethane gas stream while the bottom liquid stream from the absorber is subsequently distilled for the generation of a stream consisting predominantely of propane, butane and other heavy hydrocarbon components. Alternate embodiments include an additional reflux separator in the system, or substitution of an additional absorber for the separator.

Title: Tracking and finding lost messages in a network
Inventor: ALDRED BARRY K
IPC: H04L12/58
Filed: 1999-09-29
Abstract: Messages sent over a network may include a flag to indicate that they are traceable. When a message is received at a data processing unit the flag is checked and if the message is traceable then information identifying the message and the next data processing unit that it was forwarded to are stored. A tracer message may be sent by the data processing unit which generated the traceable message. When this is received by another data processing unit, it determines if the message identified by the tracer message is present in the processing unit and notifies the originating unit if it is, if not it determines if it has information stored about the identified original message. If it does the tracer message is forwarded to the data processing unit that the original traceable message was forwarded to, based on the stored information. The network may be an asynchronous message queuing network.

Title: Fire risk elimination for flammable-liquid-filled transformers
Inventor: BASTIAN JUERGEN
IPC: H01F27/16
Filed: 1999-10-20
Abstract: A transformer arrangement comprises a first tank containing a transformer which is filled with an oil 1. The first tank is itself located in a second tank 15 which is then filled with an inert atmosphere. The said inert atmosphere comprises 95 % nitrogen, which is not used for cooling. The transformer is cooled using heat exchanger arrangements. A cascade of various heat exchanging formations, involving oil, water, alcohol and/or air and vacuum, evaporation or condensation conditions, may be used as remote cooling means. At least part of the heat exchanging system may be located inside or outside the confines of the inert gas filled tank 15. The inert gas surrounding the oil filled transformer prevents oxygen from entering the first tank when the said tank develops a leak, thus reducing the fire risk. The arrangement further facilitates the recuperation of heat lost from the transformer whilst stabilizing the temperature and pressure of the transformer allowing better fault detection.
