The invention provides a knock-down, lightweight, thermally insulating, shipping container made at least in part from a polymer core covered by a thermoplastic sheet layer. In an embodiment of the invention, the shipping container is modular, being adjusted to suit the item(s) to be shipped. In an embodiment of the invention, the base, top panel and walls are made of expanded polystyrene core and combined with high impact polystyrene surface. In one embodiment, a mesh is introduced into the core to strengthen the core making the shipping container tamper proof. A shipping container bag that is light weight, strong, made of a fire retardant material and which forms an ultra violet light, weather and dust barrier can be used to store the shipping container. A system and method for supplying, dispensing, positioning, tracking, transporting, forwarding and storing the light weight shipping containers based on the shipping container bag is disclosed.

Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes an encoder wheel assembly in addition to or instead of a chip for determining toner load. It may be desirable to alter the encoder wheel or part of the cartridge, either by the printer or the cartridge, to permit a deliberate end of life function situation that requires the replacement of the cartridge, encoder wheel, or encoder wheel assembly components. This thereby controls the remanufacture or replacement of the toner cartridge in a way that is desirable to the manufacturer and prevents unauthorized refilling of the cartridge.

A backwashable filter element consists essentially of a fabric of polyacrylonitrile fibres wherein the diameter of the fibres is in the range 10 to 50 microns and the density of the element is in the range 0.05 to 0.50 g/cc. The element is suitable for use in filtering sea water, particularly for sea water injected into petroleum reservoirs to assist in the recovery of crude oil.

Emulsions of oil and water are broken by treating them with a demulsifier which is a polysiloxane polyalkylene oxide copolymer in which the polyalkylene oxide segment is composed of random ethylene oxide and propylene oxide units.The demulsifier is particularly useful in breaking emulsions of water in crude oil which are normally difficult to separate and in breaking emulsions at relatively low temperatures, e.g. 30.degree. to 45.degree. C.
