Patent GB-2309078-A (GB)
Title: Inspection system for detecting defects
Inventor: AHMED MOHAMED SAMI
IPC: G01N21/89
Filed: 1997-01-08
Abstract: An inspection system comprising a line-scan sensor connected to transmit frames 11, 12 of acquired data sequentially to two channels C1, C2 of image processing means can detect defects which appear in successive frames as two parts that are individually too small to be recognised as defects. Objects to be inspected are moved past the line-scan sensor (or vice versa), and adjacent data-containing frames are caused to overlap at their respective leading and trailing edges so that some lines of acquired data from any given frame are transmitted simultaneously to both channels. Objects on an endless conveyor may be automatically rejected when they reach a mechanism downstream of the sensor by synchronising the outputs of the two channels with the conveyor. Bones in chicken pieces using X-rays, particles in a flowing fluid, or textile or paper webs may be monitored. The height of inspected objects may be measured.
Patent GB-2309718-A (GB)
Title: Downhole tool with torque-resistant slip
Inventor: LEMBCKE JEFFREY J
IPC: E21B33/129
Filed: 1997-01-27
Abstract: A downhole tool, such as a bridge plug or packer, is supported by one or more slips 36 against rotational forces, such as those imparted from a whipstock during milling operations, as well as longitudinal forces, such as those due to uphole or downhole pressure fluctuations. The slips 36 are supported by the tool in such a way that application of torque to the tool causes the slips 36 to bite further into the casing c and increase their gripping action. This may be achieved by wedging, levering or camming the slips 36 into the surface of the casing c. The gripping action is further improved by the provision of one or more wickers 50 on a radially outer surface of each slip, the wickers 50 being oriented either obliquely to or substantially parallel to the longitudinally axis of the downhole tool. Once the tool has been set the slip support system acts to enhance the gripping action of the slips 36 regardless of the direction of the applied torque.
