Title: High level carbonate and/or oxidant hair colouring compositions
Inventor: MARSH JENNIFER MARY
IPC: A61K8/41
Filed: 2005-12-01
Abstract: The present invention relates to an oxidative hair colouring and bleaching composition comprising an oxidizing agent, a source of carbonate ions, and an alkalising agent, wherein the composition comprises at least 4% by weight of hydrogen peroxide or a source of carbonate ions, utilised at pH 9.5 and below and wherein said composition is free of a source of radical scavengers which result in improved lift and lightening for blonde shades, excellent dye deposition and colour and improved grey coverage.

Title: Device and method for retrieving debris from a well
Inventor: TELFER GEORGE
IPC: E21B21/12
Filed: 2006-05-12
Abstract: A device (12) is disclosed which is for use in retrieving debris from a well.  In one embodiment, the device includes an elongate body (20); a main bore (22) extending part way along a length of the body, along which fluid flows into the device; an opening (24) towards a lower end of the body; a main fluid chamber (28) in the body in fluid communication with the main bore; a flow restriction (30) provided in the main bore, through which fluid flows from the main bore and into the main fluid chamber; at least one chamber outlet (32) for . directing fluid from the main fluid chamber into an annulus defined between the device and a well borehole wall; a return flow passage (40) extending between the body opening and the main fluid chamber, for return flow of fluid from the annulus to the main fluid chamber, to facilitate retrieval of debris from the well; and at least one fluid exit (44), for flow of fluid returned to the main fluid chamber through the return flow passage out of the device. In use, fluid flowing through the main bore is accelerated through the restriction such that the pressure of fluid exiting the restriction is lower than at a location upstream thereof, to draw part of the fluid returned to the main fluid chamber through the return flow passage into and through the chamber outlet, thereby recirculating said part of the fluid into the annulus.  This assists in the retrieval of debris from the well.

Title: Transdermal drug delivery device comprising extensor-relaxor means
Inventor: CHOWDHURY DEWAN FAZLUL HOQUE
IPC: A61K9/00
Filed: 2005-06-06
Abstract: A transdermal drug delivery device comprises a reservoir layer (10), which consists of one or more chambers (24) for containing a drug. A lower surface of the reservoir layer (10) is bounded by a resilient membrane (12), which is perforated by pores (26) through which the drug may be delivered from the chambers (24). Connected to the reservoir layer (10) is an extensor means (18), which can be actuated by control means (22) to deform the reservoir layer (10) such that the chambers (24) are compressed and the pores (26) are enlarged, thereby forcing the drug from the chambers (24) through the pores (26) and into contact with the patient~s skin (30). When the resilient membrane (12) is adhered to the skin (30), the extension and relaxation of the device causes simultaneous stretching and relaxation of the skin (30), disrupting the barrier presented by the skin~s surface and enhancing delivery of the drug.

Title: Extraction of co2 gas from engine exhaust
Inventor: COPELAND MADISON M
IPC: B01D53/62
Filed: 2008-04-30
Abstract: A photo-bioreactor is used for extraction of carbon dioxide from exhaust gases of an engine used for compression of natural gas by providing a series of vessels and in each contacting the gases with a labyrinthine flow of water containing photo-synthetic organisms. Each vessel receives the gases in series and is controlled to manage the temperature and dwell time to take into account the reducing CO2 content. The gases are introduced using directional diffusers at the bottom of the bath which generate a flow in the water. Each vessel has a separate water supply and harvesting system so that the excess organisms grown are extracted from each for harvesting. A gas recirculation system is controlled to manage the gas dwell time in the vessel. The divider walls contain the electrically powered lights between two transparent sheets.
