Title: Production of polyurethane foam having no cell membrane
Inventor: KUMASAKA SADAO
IPC: C08J9/38
Filed: 1985-05-01
Abstract: PURPOSE:To obtain a polyurethane foam having good air permeability, by applying an org. solvent to an open-cell non-rigid, polyurethane foam sheet and simultaneously blowing compressed air thereon to remove cell membranes. CONSTITUTION:An org. solvent is applied to an open-cell non-rigid polyurethane foam sheet to allow it to swell. Compressed air is blown on the swollen foam sheet to remove cell membranes. Examples of the org. solvents are halogenated hydrocarbons, aliph. hydrocarbons, arom. hydrocarbons, alcohols and ketones. They may be used either alone or as a mixture thereof. Low-boiling halogenated hydrocarbon solvents are particularly preferred from the viewpoints of activity and workability.

IPC: B26F3/06
Filed: 1994-05-06
Abstract: PURPOSE:To enhance the aligning accuracy in stacking metal sheets and eliminate likelihood of material-originating trouble in the next stage of process by putting each product item and parent material in tight attachment to the surface of a table made of electrical insulating material using sheet holders, and separating the cut piece produced from the fusion cutting process while it is held in the flat attitude. CONSTITUTION:When a current is fed while an electrode 5 is pressed to a product item 2, a parent material 1 and the item 2 positioned near a micro-joint part 13 are put in tight attachment to a table 3. On the electrode 5 side, a sheet holder 9 is pressed from above by an air cylinder 11, while sheet holder 10 is from above pressed by another air cylinder 12 on the counter-electrode 5 side. Thereby the parent material 1 and product item 2 can be tightly attached to an electrical insulating plate 4. If current is fed in this condition for performing the fusion cutting, it is possible to ensure a segregated structure free from attachment of any molten particles. As a result, molten particles drip and solidify, and there is no risk that they attach to the undersurface of the product item 2 to build projection (s) protruding in the direction across the thickness.
