Patent EP-0464144-B1 (EP)
Title: A multilayer film and laminate for use in producing printed circuit boards
Inventor: IMFELD STEPHEN M
IPC: B32B15/08
Filed: 1990-03-22
Granted: 1997-08-06
Abstract: A multilayer film having as one surface layer thereof a support layer containing a thermoplastic resin able to withstand temperatures up to 200 degrees C. without softening and the other surface layer an adhesive layer containing a thermoplastic resin having a melting point ranging from about 100 to 200 degrees C. Optionally, a tie layer may be employed between the support layer and the adhesive layer. The multilayer film is useful as a protective carrier sheet for a cladding metal foil used in the production of printed circuit boards. The carrier sheet provides temporary, peelable surface protection for the cladding metal foil preventing contamination and physical damage to the foil both before and during printed circuit board formation. Adhesion of the carrier sheet to the cladding metal foil, measured using a 180 degree peel test is less than 0.4 pounds/in-width and greater than 0.005 pounds/in-width, and preferably less than 0.1 pounds/in-width and greater than 0.01 pounds/in-width.

Date Dec. 13, 1990.A frequency-doubled laser contains laser diodes as a pumped light source and a resonator (R) comprising in the stated order a first mirror (5), a laser medium (6), a Brewster plate (7) as a polarizer, a nonlinear crystal (8) for frequency doubling and a plane mirror (9) as an output mirror. The plane mirror ensures that shifts of rays taking place within the nonlinear crystal remain in the radiation area even when returning through the crystal, in contrast to the prior art which uses a concave mirror as an output mirror that causes shifted rays from the nonlinear crystal to be deflected out of the beam path. The inventive measure achieves a laser light that has high efficiency and is virtually free from intensity fluctuations.

Abstract: A contact component for the toolless contacting of insulated electric conductors consisting of a conductive metal core (62) and insulation surrounding it comprises a contact blade (26) having a slot (38) fitted with a cutting edge (40). The insulated electric conductor (52) may be drawn into the slot through an entry. Here the insulation is cut through so that the metal core (62) makes contact with the edges (42, 44) of the slot (38). To facilitate handling and make tools superfluous, the conductor (52) may be pushed into a concave guide surface (20). The contact blade (26) is arranged in such a relative position to the guide surface (20) that tension on the conductor draws it into the slot (38) and the free end (60) of the conductor (52) is supported against deflection on the wire supports (20).

Abstract: Closed system and process for the conversion of gaseous or vaporizable organic and/or organo-metallic compound to inert solid which is resistant to solvent extraction, and is itself essentially nontoxic or convertible through oxidation or other natural processes to a toxic material. This process involves a low temperature, low energy conversion in a close system, of an organic and/or organo-metallic material by initially fragmenting such material into its basic elements follow thereafter by randomly recombining such elements as a solid coating or deposit upon a substrate. In the preferred embodiments of this invention, the toxic and/or potentially toxic material is injected as a gaseous phase into a chamber where it is subjected to an RF energy source, thereby forming a plasma which is contained within the chamber by a magnetic field. The chamber, as well as, the other components of the conversion system are maintained under a negative pressure which allows for the transport of the plasma throughout the system to a second chamber where the elements of the plasma can recombine in a random fashion. The recombination of these elements as a solid allows for ease of handling and prevents their release into the atmosphere or ground water. Compounds which can be subjected to this process include chlorinatehydrocarbons i.e., methylenechloride, carbontetrachloride and chlorofluorocarbons (i.e., Freons).

Abstract: The invention concerns a gelling material for gelling aqueous fluids, medical wastes containing aqueous fluids, body fluids collected by suction in body fluid suction equipment. The gelling material comprises a water-absorbent composed of a water-absorbing resin in the form of powders or granules, the water-absorbent being wrapped in water-disintegrating paper or a water-soluble film or a laminate sheet obtained by laminating water-disintegrating paper and a water-soluble film. The invention also concerns a method of gelling aqueous fluid and medical waste by adding the gelling material to the aqueous fluid or medical waste. The aqueous fluid or medical waste can be gelled conveniently and in a short period of time. The gel thus produced never releases absorbed fluid even when an external pressure is applied to it. Thus, the invention is useful for the treatment of aqueous fluids such as sludge-like wastes produced in plants and also of medical wastes and body fluids. <IMAGE>
