Tesco PLC is a British multinational grocery and general merchandise retailer headquartered in Cheshunt, Hertfordshire, England, United Kingdom. It is the third largest retailer in the world measured by profits and second-largest retailer in the world measured by revenues. It has stores in 12 countries across Asia and Europe and is the grocery market leader in the UK , the Republic of Ireland, Hungary, Malaysia, and Thailand.Tesco was founded in 1919 by Jack Cohen as a group of market stalls. The Tesco name first appeared in 1924, after Cohen purchased a shipment of tea from T. E. Stockwell and combined those initials with the first two letters of his surname, and the first Tesco store opened in 1929 in Burnt Oak, Barnet. His business expanded rapidly, and by 1939 he had over 100 Tesco stores across the country.Originally a UK-focused grocery retailer, since the early 1990s Tesco has increasingly diversified geographically and into areas such as the retailing of books, clothing, electronics, furniture, toys, petrol and software; financial services; telecoms and internet services. The 1990s saw Tesco reposition itself, from its perception as a downmarket "pile 'em high, sell 'em cheap" retailer, to one which appeals across a wide social group, from its Tesco Value to its Tesco Finest ranges. This was successful, and saw the chain grow from 500 stores in the mid-1990s to 2,500 stores fifteen years later.Tesco is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index. It had a market capitalisation of approximately £20.5 billion as of 4 August 2014, the 28th-largest of any company with a primary listing on the London Stock Exchange. Wikipedia.

Present embodiments are directed to a circulation system including a circulation management system. A housing of a coupling feature of the circulation management system is configured to extend over a box end of a pipe element. A seal disposed within the housing is configured to engage with a face of the box end. A force-application feature is configured to force the seal against the face of the box end to establish a sealed engagement between the circulation management system and the pipe element. A flow path of the circulation management system extends through the housing and the seal, wherein the flow path facilitates fluid flow into the pipe element from the circulation management system when the sealed engagement is established. A port to the flow path is configured to couple with a fluid flow supply feature.

A drilling system includes a multi-function sub configured to be coupled to a top drive of a drilling rig and configured to be coupled to a tubular in order to selectively transfer a torque from the top drive to the tubular. The multi-function sub includes a torque sensing component configured to measure the torque provided from the top drive to the tubular via the multi-function sub, a clutch configured to suspend a transfer of torque from the top drive to the tubular when the clutch is released, and a clutch actuator communicatively coupled to the torque sensing component and configured to release the clutch when the torque measured by the torque sensing component is greater than a threshold torque value. The multi-function sub also includes a compensator configured to enable the multi-function sub to move the tubular in an axial direction relative to the top drive.
