Title: Gel method for preventing water-influx
Inventor: PHELPS CRAIG HENLEY
IPC: C09K8/50
Filed: 1993-11-16
Abstract: A method to prevent damage to a water-sensitive hydrocarbonaceous fluid-producing zone (14) of a formation (10) which is penetrated by a well (12) which has a water-influx problem. A gellable petroleum mixture is injected into the well where it forms a solid hydrophobic gel in situ sufficient to temporarily close pores in the water-sensitive zone. The mixture is allowed to remain in the water-sensitive zone (14) for a time sufficient to form a solid gel so as to preclude fluid entry into the water-sensitive zone (14). Afterwards, an aqueous based gel mixture is injected into the water-influx zone (16) where it forms a solid hydrophilic gel which is substantially stable thereby precluding fluid entry into the well. Subsequently, the solid petroleum gel degrades at formation conditions and opens the water-sensitive zone (14) to production of hydrocarbonaceous fluids. Thereafter, substantially water-free hydrocarbonaceous fluids are produced from the watersensitive zone (14).

Title: Multimedia moving picture and audio data reproduction control in response to a skip command to a desired picture
Inventor: SAKAMOTO HIDEO
IPC: H04N7/173
Filed: 1997-06-26
Abstract: A moving picture data reproducing system has a server 11 and a terminal 12. The server sends compressed moving picture and audio data to the terminal corresponding to a command issued from the terminal. The terminal reproduces moving picture and audio data corresponding to the compressed moving picture and audio data. The server starts sending the compressed moving picture and audio data that start from a designated skip position after the lapse of a predetermined time period without a protocol performed in a control portion when the terminal sends a skip reproduction command to the server while the terminal is reproducing a moving picture and causing the terminal to reproduce the moving picture that start from the designated skip position when the terminal receives the compressed moving picture data that start from the designated skip position. A part of communication performed in the control portions is thus omitted. Thus, processes after a skip reproduction request is issued until moving picture and audio data are reproduced are performed at a high speed.

Title: Vectors which express a coloured protein for detection of integration into a cell
Inventor: OEHLER STEFAN ANDREAS
IPC: C12Q1/68
Filed: 1997-08-16
Abstract: A process for the detection of integration of transformation vector DNA into a target cell comprises the insertion, into said DNA, of a DNA sequence which either encodes a coloured protein or encodes a protein which develops colour on exposure to an appropriate co-factor. The said sequence may be used in the production of a reporter construct by operatively linking thereto a regulatory element from a gene, especially for the transformation of plants and animals. The preferred protein is either a cytochrome (in which the co-factor is an iron ion), especially cytochrome ba3 of Thermus thermophilus (in which the cofactor may be a copper ion), or a carotenoid binding protein (in which the co-factor is the appropriate carotenoid).

Title: Locating a mobile telephone using time of arrival measurements
Inventor: LUDDEN BRENDAN PATRICK
IPC: G01S5/06
Filed: 1998-06-10
Abstract: Apparatus and method for determining the location of a subscriber unit 1 in a mobile telecommunications network and particularly in a GSM cellular network, includes the provision of several receiver or "slave" stations 4, 5, 6, controlled by a "master" base transceiver station 2 and positioned at separate known locations within each cell. Each of the receiver slave stations 4, 5, 6, which are synchronised by means of an on-board GPS receiver clock (10 fig. 2), measures the time of arrival of a signal (e.g. fill frame) transmitted from the subscriber unit 1. The time of arrival measurements recorded by each "slave" station 4, 5, 6 are then transmitted (e.g. via SMS, GPRS or USSD) to a computation device 3 for computation of the subscriber unit's 1 location relative to the "slave" stations 4, 5, 6. The computation device 3 may be provided at the "master" station. In operation, the "master" station may on reception of a location request from the subscriber unit 1 or network, perform a rough estimate of the location of the unit 1 using GSM data (e.g. power measurement, timing advance data etc), decide which "slave" stations 4, 5, 6 to use in the location determination and then instruct the "slave" stations to start receiving signals and the subscriber unit 1 to transmit a signal burst. Power and signal quality estimates may be provided along with time of arrival and spatial or polarisation diversity techniques may be used to improve sensitivity,(e.g. reception of two successive signal bursts on different antennas at the slave stations).
