Title: Inducing torsional vibration in a drill string for friction reduction
Inventor: WORRALL BOB
IPC: E21B28/00
Filed: 2009-05-01
Abstract: A method of conducting borehole operations using a downhole tool positioned in borehole by means of an elongate tubular drill string comprises imposing a torsional vibration upon the tubing string at a frequency of less than about 5 Hz. The vibration may be controlled to a predetermined length of the string, or may encompass its entire length. The operation may be a drilling operation, and the downhole tool a drilling assembly. The string may comprise a coiled tubing. A suitable vibrator may comprise a high torque, low speed electric motor located at the same end of the tubing as the drilling assembly. The vibration may be monitored and a feedback signal produced to be used in controlling the vibration frequency. The vibrations will reduce the amount of friction between the tubing and the walls of the borehole.

Title: Processing electronic receipts
Inventor: PHILLIPS GARETH
IPC: G07G1/14
Filed: 2009-09-14
Abstract: An electronic receipt server is described which, upon receiving receipt data associated with a customer purchase transaction from a first entity 601, generates a reference associated with the customer purchase transaction 602, stores the receipt data in the data store in association with the reference 603 and returns the reference to the first entity 604. On receipt of a request including the reference from a second entity 605, the server sends an electronic receipt to the second entity 608, the electronic receipt being associated with the reference, and presents the customer purchase transaction according to the receipt data. A point of sale system sends receipt data to a first entity (e.g. receipt server) and receives a corresponding reference back. The POS system then embeds the reference in a message associated with the transaction to a second entity (e.g. acquiring server). Image watermarking may be used for the receipt and the reference may be generated as a hash of the card number or a timestamp.
