Title: Apparatus and method for cementing a liner in a well bore
Inventor: BAUGH JOHN LINDLEY
IPC: E21B33/16
Filed: 1983-02-11
Abstract: An apparatus and method for cementing a liner in a well bore utilizes a setting tool 19 having an end 49 adapted to be connected in a pipe string for extension through the liner and having an opposite end. Seal means 59 are carried by a select one of the setting tool 19 and liner 21 for forming a seal between the liner 21 and the exterior of the setting tool 19 in the annular space which is created when the tool is extended within the liner. A wiper holder 99 is connected to the setting tool opposite end and has an interior bore 101 for receiving a wiper plug 103. In the method, the setting tool 19 is lowered with the liner attached thereto into the well bore. Seals 59 on the exterior of the setting tool 19 engage the interior of the liner 21. The liner is then anchored in the well bore after which the setting tool 19 can be released from the liner. The setting tool is moved a selected distance to insure that the tool is disengaged from the liner with the wiper plug 103 being at least partly contained within the wiper holder 99 during such steps. Cement is then pumped into the liner through the operating string and setting tool mandrel. A pumpdown plug (not shown) sealingly engages the operating string and mandrel behind the cement and is pumped into engagement with the wiper plug 103. Cement is pumped out of the liner into the surrounding well bore by forcing the pump down plug and wiper plug through the liner. The setting tool is then removed from the well bore by withdrawing the operating string. <IMAGE>

Title: Method and apparatus for deriving currents and potentials representative of the impedance of zones of a body
Inventor: SMITH DENIS NIGEL
IPC: A61B5/053
Filed: 1984-04-13
Abstract: In deriving the impedance of a zone of a body errors arise when currents used stray from the zone due to movements of, and/or changes within the body. In the invention the current used for deriving the impedance is passed through a zone 16 using electrodes 5 and 8 outside the zone and the potential also required for deriving the impedance is sensed at two electrodes 12 and 13 at ends of the zone. The current is confined to the zone by passing control currents between control electrodes 4 and 7, and 6 and 9 to set up virtual current-barriers along the boundaries of the zone. Pairs of electrodes 11, 12; 12, 14, 11, 13 and 13, 15 straddling the boundaries are used to adjust currents passed by the control current electrodes to establish the positions of the boundaries and to stabilise these positions when movement and/or internal functional change occurs. Virtual barriers may be established between a plurality of impedance measuring zones by placing larger arrays of electrodes on the front and back of the body or around the body. <IMAGE>

Title: Equipment for handling loads
Inventor: BLACKSTONE CHRISTOPHER EDWARD
IPC: B66C13/06
Filed: 1985-06-20
Abstract: Load handling equipment comprises an overhead structure 1 movable along a beam 20, and a load support 2 which is suspended underneath the structure 1 by cables 9 and 10. The cables 9 and 10 are wound around a winding drum 6 powered by an electric motor 7. The cables 9 and 10 pass over respective pulleys 11 and 12 on the structure 1 and then downwardly under respective pulleys 15 and 17 on the load support 2 before passing around a common control drum 19. The cables 9 and 10 then pass under respective pulleys 16 and 18 on the load support 2 and then upwardly to be anchored at 13 and 14 with respect to the overhead structure 1. The provision of the common control drum 19 prevents swinging of the load support relative to the structure 1 in the forward and backward directions because of the tendency of the cables 9 and 10 to rotate the control drum 19 in opposite directions at the same time when the load support 2 is displaced out of a predetermined position relative to the overhead structure 1. <IMAGE>
