Patent GB-2018985-A (GB)
Title: Detecting Flaws in Sheets
IPC: G01N21/89
Filed: 1979-05-11
Abstract: Method and apparatus for detecting holes or surface flaws in sheet material such as tinplate 10 moving in the direction of the arrow where a beam from a laser passing through a modulator (not shown) is scanned by a mirror drum 14 across cylindrical mirror 16 and plane mirror 17 to produce a slit shaped beam and the light passing through a hole is received by a bunch of light guides 22 and passed to a photomultiplier 36. Light reflected from the sheet surface strikes semi-diffusing retro-reflector 61 and travels back along a path similar to that of the original beam to second photomultiplier 63 which registers faults on the sheet surface which are characterised by changes in reflectivity. The output of photomultiplier 36 is also used to control the modulator hence the scan. Potential scan errors at the sheet edge are corrected by a half-wave plate (Figures 10, 11). Holes not substantially normal to the plane of the sheet may be detected by a dual- beam scanning arrangement (Figure 6). The position of a flaw can be detected by correlation of its resultant signal with a signal related to the scan. <IMAGE>

Patent GB-2052793-A (GB)
Title: Settlement tank sludge removal
IPC: B01D21/00
Filed: 1980-03-11
Abstract: The apparatus for the sludge removal provides selective and steady flow conditions for variable sludge qualities, free of pulses or surges which contribute to water flowing in preference to denser sludges. Flow is created by the temporary application of a vacuum to an inverted bell 4 which envelopes the top of a vertical withdrawal pipe 3 connected to the tank bottom, the sludge entering the bell subsequently discharging through an orifice 22. Control of operations can be suited to needs as follows:   (1) Start up is by an electrical timer. Shut down is by measuring increased head at a discharge orifice caused by increased flow rates of thinning sludges. (2) Start up and shut down is controlled by switches operated by pressure or buoyancy devices, located in the tank or withdrawal pipe, which are sensitive to density changes.   Electrical power failure during operation will cause a valve to vent the apparatus to atmosphere and thus fail safe. The vacuum can be created by hand pump should electrical power be unavailable. <IMAGE>
Patent GB-2047063-A (GB)
Title: Linkage for a number of farm implements
IPC: A01B73/06
Filed: 1980-04-09
Abstract: This invention is a linkage for enabling a number of rollers (13,14) to be towed by a single tractor, side rollers (14) being capable of being in an in-line position behind the central roller (13) for moving from field to field, or in a laterally extended working position with their inner ends in line with the outer ends of the central roller. In Figure 1, (not shown), a side roller (14) is pivotally connected on a frame (17) pivotally connected on the central roller frame (12) and moved between its two positions by an actuator (19). In Figure 2 a side roller (14) is towed by a link (21) whose angle with the roller frame (15) is adjusted by the actuator (19) so that the roller will assume one or other of its positions. The actuators can be operated from the towing tractor so that the user does not have to dismount, or can each be replaced by a pair of links of fixed length, either one of which can be used after manual adjustment of the angle. <IMAGE>

Title: An artificial breathing device
IPC: A61M16/00
Filed: 1980-04-17
Abstract: A device for artificial respiration is attached by an unobstructed air duct 10 to the outer end of a flexible endotracheal tube or to a breathing mask. It is provided with a regulating valve 2 which has its inlet side connected to an oxygen supply via an "on-off" time-cycling apparatus of known design, while its outlet side is connected to the air duct 10 through a small-bore tube 14 which extends close and parallel to the air duct wall in the direction towards the mask or the endotracheal tube. Oxygen passing through the small-bore tube 14 into the air duct 10 at great velocity draws air from the outside by injector action and presses it into the lungs of a patient. Upon the end of the "on" part of the cycle the air is expelled by the elasticity of the lungs and of the chest cavity and can freely escape through the unobstructed air duct, which likewise permits the ejection of mucus, blood and other excretions. <IMAGE>

Title: Well-logging system and method
IPC: G01V11/00
Filed: 1980-09-22
Abstract: In a well logging system all logging measurements are derived in digital form and on the same depth-dependent basis, whereby measurements taken during one trip through a borehole may be combined with other logging measurements taken during a different trip through the same borehole, and whereby all of the measurements may then be processed at one time to derive various lithological indications. The logging measurements and lithological relationships may also be correlatively displayed on a real- time basis with respect to at least some of the logging measurements from which they are derived. Visible representations of such lithological relationships are generated to provide qualitative and quantitative indications of subsurface earth characteristics along the borehole. Such indications may be in both a linear and in a non-linear or symbolic form, and may also be recordable. <IMAGE>
