Title: Removing deposit from oyster shells - by high-frequency beating with non-round rotating body whilst supporting oysters on flexible surface
IPC: A22C29/04
Filed: 1979-11-15
Abstract: The arrangement is intended for removing deposits from the shells of shellfish such as oysters. The oysters are placed on a flexible support surface and the shells beaten with high frequency on their upturned faces. The shells may be cleaned by spraying after this operation. The support may be a driven flexible endless belt and have a number of beating elements arragned over it. Each element may consist of a rotating body with non-circular cross-section such as a link chain, which longitudinally extends across the belt at a short distance above it. Eliminates labour-intensive manual cleaning operation.

Patent NL-8105872-A (NL)
IPC: B01D33/00
Filed: 1981-12-28
Abstract: A washing column for the continuous separation between a solid chemical formed in a liquid multi-component system, on the one hand, and the mother liquor in which the solid chemical is suspended, on the other. In a cylindrical working space a stationary, straight, plane washing front is maintained in a packed bed of the solid chemical substance between the mother liquor, on the one hand, and a melt of the solid chemical, on the other. According to the invention, the washing column is double-walled to form an enveloping space, which contains a heat insulating medium and can be pressurized to conform to the pressure within the column. This construction permits the use of a relatively thin, glass inner wall of uniform wall thickness and inner surface. This renders the column resistant to corrosive chemicals, reduces the effect of heat exchange with the surroundings, and prevents instabilities in the washing front.

Patent NL-8602402-A (NL)
IPC: B01D71/40
Filed: 1986-09-23
Abstract: This invention relates to a process for the preparation of hydrophilic membranes by coagulation of a solution of at least one hydrophobic polymer and at least one hydrophilic polymer in a suitable solvent medium on a coagulation medium. The process according to the invention is characterized in that hydrophilic microfiltration and/or ultrafiltration membranes are prepared by cross-linking the hydrophilic polymer which is present in or on the obtained membrane matrix after the coagulation in an essentially non-swollen state and fixing same as such in or on the polymer matrix. Advantageously the solvents and the undesirable components of the coagulation medium are removed whereby the hydrophilic polymer is converted into an essentially non-swollen state prior to cross-linking. The removal of the undesirable components from the membrane takes place by means of a non-solvent for the hydrophilic polymer according to the invention. Finally the invention relates to hydrophilic microfiltration- and/or ultrafiltration membranes, flat or tubular of a hollow fibre structure.
