Title: Composite foamed articles and process for their production
Inventor: BRADBURY JOHN ALBERT AVERY
IPC: B32B5/18
Filed: 1983-05-27
Abstract: Composite foamed organic materials made by impregnating an open-celled organic foam (flexible or non-flexible) with an aqueous suspension of an insoluble solid additive to deposit the solid particles within the cells, and then drying. Organic foams and additives may be varied widely, but preferred foam is a rubber or polyurethane and preferred additives are layer-mineral type, especially a vermiculite, montmorillonite or bentonite. Products can be impregnated uniformly or have impregnant locally concentrated in controlled fashion, e.g. in surface zones, to get specialised properties. Additives can impart filling or other properties, but especially fire-retardancy, which can be combined with rigidising or retention of resiliency. Impregnated products can be given optional after- treatments, e.g. surface coating.

Title: Testing for the presence of living organisms at the surface of an object
Inventor: IRISH DOUGLAS
IPC: G01N21/76
Filed: 1985-08-07
Abstract: A method of determining the quantity of living organisms at the surface of an object involves applying a bioluminescent agent, for example firefly luciferin-luciferase enzyme, onto the surface, conveniently by spraying. NRB nucleotide releasing reagent is then sprayed onto the surface wetted with the enzyme solution. As the ATP-bearing cells of any micro organisms present at the surface of the sample are disrupted by the releasing agent, the ATP is released into an environment of firefly enzyme whereby bioluminescence is emitted in the immediate vicinity of the cell from which the ATP was released. The luminescence is then monitored by apparatus which has a display device which may be calibrated to indicate the level of the emitted luminescence, or where a particular organism is to be detected directly in quantity of organism per unit area.
