Patent DE-4008046-A1 (DE)
IPC: B32B38/08
Filed: 1990-03-14
Abstract: A moulding is produced from thermosetting melamine resin foam by treating the foam with a thermosetting binder and moulding it hot. Pref. binders are phenolic or melamine resin in various forms. - Foam sheeting (2) is fed into two counter-rotating rollers (5,6) via guides, the gap between (5) and (6) being less than the foam (2) thickness. Foamed binder (3) is fed in also from supply tubes (7,8). The action of the rollers (5,6) applies the binder (3) on to the main foam (2). A device (9) traps excess binder. When the foam leaves the rollers (5,6) it expands again to its original thickness, and surfacing mats (10,11) can then be applied if desired. If the mats are used the assembled materials are passed through two more counter-rotating rollers (12,13) and the flat product is cut into lengths. These are finally hot press moulded to desired shape.

Title: Animal skin component separating - uses pressure jet stream of fluid medium directed at an angle to the surface
Inventor: FIEDLER ULRICH DIPL ING
IPC: C14B1/02
Filed: 1990-03-30
Abstract: For the selective sepn. of components from animal skins and pelts, for further processing such as in the pharmaceutical or cosmetics industries, a medium is used at a pressure of 0.5-15.0 Mpa directed at an acute angle in one or more streams at the surface being worked of the skin or pelt, or parallel to the surface. A transport system gives relative movement between the surface of the skin or pelt in relation to the jet or jets. The gap between the surface of the skin or pelt and the jets remains constant. A fluid, pref. water, is used as the medium, or air can be used, or the medium can be an air/water mixt. The pressure of the medium is adjusted according to the nature of the skin or pelt and whether the components to be separated are soluble or insoluble. The adjustments are made over time according to the working. The selection of the angle of the medium stream against the skin surface and the deg. of relative movement and movement direction are also determined according to the nature of the material and whether the sepd. components are soluble or insoluble. The medium is delivered intermittently. ADVANTAGE - The system gives a selective removal of components from animal skin or pelt, with min. appts. and maintenance.
