Patent DE-3382402-D1 (DE)
Inventor: WILKINSON RICHARD L
IPC: G11B7/26

Granted: 1991-10-10
Abstract: An optical recording medium for use with a recording apparatus of the type that focuses onto the medium, as the medium is moved in a prescribed fashion, a beam of light that is modulated in intensity in accordance with a data signal to be recorded. The recording medium includes a substrate having a smooth, planar upper surface, with a thin light-absorbing coating overlaying the surface, such coating including an explosive material such as nitrocellulose, and a light-absorbing dye. As the medium is moved with respect to the intensity-modulated beam, the explosive coating is selectively energized by the beam to induce spaced explosions therein, whereby corresponding optically readable irregularities, representative of the data signal, are formed in the outer surface of the coating. A light-reflecting material is then deposited over the coating containing the surface irregularities, and, if desirable, a plastic protective layer is deposited over the light-reflecting layer. Two of such mediums can be bonded back-to-back to form a two-sided record.

Title: Method of making a gasket
Inventor: BATE CECIL ALBERT
IPC: F02F11/00
Filed: 1984-09-03
Granted: 1987-12-23
Abstract: A gasket of the kind comprising particles of compressed expanded graphite bonded to an apertured reinforcement plate is made by pressing the graphite particles onto the face of the plate without lateral support of those particles at the periphery of the plate, as by pressing between two compressor belts. In thus dispensing with vertical moulding elements, the method enables a more uniform density of graphite to be obtained over the surface of the plate, and yet leaves the graphite coating at the periphery acceptably uniform with the remainder. 
<??>The method is specially applicable to the manufacture of gaskets for the cylinder head of an internal combustion engine.

Title: Formaldehyde-free insolubilizers for binders for paper coating compositions
Inventor: LIPOWSKI STANLEY A
IPC: C08G12/12
Filed: 1984-02-23
Granted: 1988-09-08
Abstract: A highly efficient formaldehyde-free coating composition insolubilizer is prepared by reacting about 3 moles of glyoxal with 1 mole of urea resulting in a formation of a low molecular weight oligomer in a yield of 95-96%. The molar ratio of glyoxal to urea is very critical in obtaining the highest efficiency and is kept within narrow limits. The coating compositions of the present invention possess 2 till 4 times higher wet-rub resistance than the prior art compositions.
