Patent IE-810408-L (IE)
Title: Field flow fractionation.
IPC: B03B5/00
Filed: 1981-02-26
Abstract: The method described is useful in field flow fractionation techniques for reducing separation times and improving the convenience and accuracy of measuring sizes or molecular weights of particulates. In field flow fractionation, the particulates (particles or macromolecules) are subjected to a force field and a mobile phase while passing through a flow channel. This field strength is decreased exponentially as a function of time. Alternatively the flow velocity is increased exponentially as a function of time. The initiation of the change in field strength or flow velocity may be delayed a period of time. If this time delay is made equal to the time constant of the exponential decay, the range of particulate retention time that is linearly related to the logarithm of the particle size or molecular weight is increased. An apparatus for implementing the method is also described and teaches the use of a function generator for providing the desired exponential decay and delay time. The apparatus is described in implementations involving a force field.

Title: Elastomeric films and its products
IPC: B32B27/00
Filed: 1969-06-05
Abstract: Supple, microporous, breathable elastomeric films with a system of intercommunicating cells are described. The films which optionally contain inert organic or inorganic particles varying in size from about 0.02 microns to 150 microns are prepared by deposition from a solution spread on a suitable surface. Deposition is effected by exposure of the solution to a liquid which is miscible with the solvent but which does not dissolve the elastomer. The use of the film in the preparation of leather replacement compositions by integration as a grain layer in and on the surface of suitable substrates is described. For this use the selected substrate is wet with a liquid in which the elastomer is insoluble, coated with a solution of the elastomer in a solvent which is miscible with the liquid used to wet the substrate, and the wet, coated substrate is treated with additional liquid to deposit the elastomer extending into the upper strata of the substrate and above its surface.
