Title: Device and method in a cellular mobile telephone system
Inventor: BODIN STIG ROLAND
IPC: G01S5/14
Filed: 1997-09-23
Granted: 2005-10-25
Abstract: The present invention relates to a method and an apparatus in a cellular mobile telecommunication system, primarily the GSM system, to determine the geographical position of a mobile station. The distance between the mobile station and a radio base station is estimated from the propagation delay. The propagation delay is determined according to the present method where the mobile station sends access bursts to the base station which measures the access delay of the arrived bursts in the same way as an ordinary handover. No confirmation on received access bursts is sent from the base station to the mobile station and therefor the handover attempt is terminated. The connection between the mobile station and the previous base station is re-established. The measured access delay is proportional to the propagation delay and thereby also to the distance to the mobile station. The mobile position can be determined with good accuracy if values from at least three base stations are obtained, although with less accuracy if only two values are obtained. Also an access delay measured by earlier known methods can be used together with measurements achieved with the present method to determine the mobile position.

Title: Coiled tubing drilling with supercritical carbon dioxide
Inventor: KOLLE JACK J
IPC: E21B21/06
Filed: 2000-03-14
Granted: 2006-11-14
Abstract: A method for increasing the efficiency of drilling operations by using a drilling fluid material that exists as supercritical fluid or a dense gas at temperature and pressure conditions existing at a drill site. The material can be used to reduce mechanical drilling forces, to remove cuttings, or to jet erode a substrate. In one embodiment, carbon dioxide (CO2) is used as the material for drilling within wells in the earth, where the normal temperature and pressure conditions cause CO2 to exist as a supercritical fluid. Supercritical carbon dioxide (SC-CO2) is preferably used with coiled tube (CT) drilling equipment. The very low viscosity SC-CO2 provides efficient cooling of the drill head, and efficient cuttings removal. Further, the diffusivity of SC-CO2 within the pores of petroleum formations is significantly higher than that of water, making jet erosion using SC-CO2 much more effective than water jet erosion. SC-CO2 jets can be used to assist mechanical drilling, for erosion drilling, or for scale removal. A choke manifold at the well head or mud cap drilling equipment can be used to control the pressure within the bore hole, to ensure that the temperature and pressure conditions necessary for CO2 to exist as either a supercritical fluid or a dense gas occur at the drill site. Spent CO2 can be vented to the atmosphere, collected for reuse, or directed into the formation to aid in the recovery of petroleum.

Abstract: A method for producing power, in accordance with the present invention, comprises the steps of: supplying clinker form cement production apparatus to a grate cooler for cooling the clinker; and extracting hot air from the grate cooler and supplying it to a filter e.g. an electrostatic precipitator or bag filter. When an electrostatic precipitator is used for extracting particulate matter from the hot air supplied from the grate cooler, the filtered air exiting the electrostatic precipitator is supplied to an air-heat transfer fluid heat- exchanger for heating the heat transfer fluid. A working fluid is vaporized using heat in the heated heat transfer fluid and vaporized working fluid and heat depleted heat transfer fluid is produced. Heat in the heat depleted heat transfer fluid is used to pre-heat working fluid while vaporized working fluid produced in the vaporizer is supplied to a turbine for producing power. Vaporized working fluid exiting the turbine is supplied to a working fluid condenser that condenses the vaporized working fluid exiting the turbine and produces working fluid condensate that is supplied to the vaporizer. Preferably, the method includes supplying the vaporized working fluid exiting the turbine to a recuperator that heats working fluid condensate supplied from the working fluid condenser prior to supplying the working fluid condensate to the vaporizer. Furthermore, preferably, the working fluid condensate is supplied to a pre-heater that preheats the working fluid condensate and produces preheated working fluid that is supplied to the vaporizer.
