Title: Optical fluid analysis signal refinement
Inventor: DONG CHENGLI
IPC: G01N21/00
Filed: 2004-04-22
Abstract: Fluid sample data is refined by obtaining optical density data at a channel for methane, oil or another constituent and optical density data at another channel such as a water, colour or base (scattering) channel. An absorption function for this channel can be determined and used to calculate the portion of the signal at the methane or oil channel which is due to water, colour or scattering. By obtaining data at further channels, a series of equations can be solved to calculate the portion of the signal which is due to each of a plurality of factors. These portions can then be removed to give a more accurate indication of the level of methane or oil in the fluid sample.

Title: Ball-valve dispenser with resiliently biased two-part housing
Inventor: OPHARDT HEINER
IPC: F16K5/08
Filed: 2004-06-24
Abstract: A dispensing ball-valve 10 comprises a valve body formed from a top half member 14 and a bottom half member 16, enclosing a dispensing ball 20 with a fixed volume cavity therein. The ball 20 is rotatable in the valve body about axis 58 to dispense a metered quantity of a granular solid material (figure 2, not shown). The two halves of the valve body 14, 16 define bosses 54, 56 which are provided with grooves for accommodating resilient O-rings 60, 62. The O-rings 60, 62 and bosses 54, 56 therefore form a resilient biasing means which biases the two parts of the valve body together. If a particle of the solid being dispensed becomes trapped between ball 20 and valve body 14, 16, then the O-rings 60, 62 tend to deform elastically and the two housing members 14, 16 are forced apart slightly. This prevents the ball-valve dispenser from jamming.

Patent GB-2430876-A (GB)
Title: Alternating pressure mattress
Inventor: DAVIES COLIN
IPC: A47C27/10
Filed: 2005-10-04
Abstract: In an alternating mattress alternate cells are inflated before supporting cells are deflated to keep the patient stationary. Lack of movement in the patient avoids motion sickness, makes sleeping easier and is better where there are spinal injuries. The device keeps the patient stationary by actively monitoring pressures within the inflatable cells. The device inflates cells in sequence and monitors the inflated cells to an accurate pressure before deflation of the next cell occurs. This process works with any pressures, timings or sequences that are set via the control program. The use of hospital clean air and vacuum can be used in conjunction with the above device or used independently to replace any pump within existing alternating pressure devices. The use of clean air will avoid any contaminant or infectious element within the ward atmosphere from entering the device. The use of vacuum to expel the air will avoid the release of any contaminant already existing within the equipment or mattress into the atmosphere. If desired, clean air can be used without vacuum. In this case, the clean air can be allowed to escape through the top layer of the mattress below the patient to act as cooling for the patient. This air can have vapours, moisture or medicine added.
