  • Patent number: 5223037
    Abstract: A plant for the manufacture of feedthrough (through-hole plated) printed-circuit boards or multilayers which comprises four modules (1, 11, 16, 21) through which the objects (3) to be treated are passed in a horizontal continuous process. In the first module (1) the surfaces to be coated are conditioned in an alkaline aqueous solution. An oxidative pre-treatment of the surfaces to be coated takes place in the second module (11). In the third module (16) a coating of organic monomers is deposited on the surfaces to be coated. Finally, in the fourth module (21) the deposited monomers are polymerized to form an electrically conductive coating. The printed-circuit boards or multilayers (3) thus treated and made electrically conductive on the lateral surfaces of the drill-holes are then passed on for the metallization of the lateral surfaces of the drill-holes (FIG. 1).

    Abstract: In a hot runner system for injection molding, a runner block (10) has a bore (14) in a casing (12) for facewise insertion of a heatable cartridge (16) comprising a core member (30) with an inside runner (34). A flow tube (32) having flow passages (35, 36) at its face ends and/or at its periphery carries an electrically insulated (39) heating coil (38) overcast with a thermoconductive mass (V) containing aluminium. Abutting members (18) seal the runner block (10) axially. Spaced radial supports (40, 49, 69) project over the outer diameter (D) of the core member (30), hollows or recesses (41, 44) serving for minimum heat transfer at the bearing area. An outer sleeve body (20) of the flow tube (32) may have sections (21 to 24) with a recessed central portion (46) sealingly engaging a collar-type support (40). Narrow peripheral ribs (42, 50) axially separate ring pockets (41) and outer compartments or spaces (52).

  • Patent number: 5213645
    Abstract: Here is disclosed a method for efficiently attaching elastic members around leg-holes of a garment such as a disposable diaper or the like without any futile use of material.Elastic members 04A, 04B are fed and bonded onto a web so that the respective elastic members described curves like sine curves with summits and troughs of these curves defining together respective annular elastic areas 16 and thereby a base web is formed. Then the base web is severed into strips 17' bearing thereon the individual annular elastic areas and these strips 17' are intermittently bonded to a web 07 to form a composite web 19. A separate web is bonded onto a top surface of the composite web 19 to form a composite web 20. Finally, the composite web 20 is severed along center lines of the respective annular elastic areas 16 into individual garments.

  • Patent number: 5209654
    Abstract: A fluid pump, particularly an extracorporeal blood pump, comprises a pump chamber (1) having an inlet opening (2) and an outlet opening (3), each connected to a respective non-return valve (4,5). The inlet (1) and the outlet (2) are movable in relation to each other and connected to a drive means (6) for periodic displacement of the inlet and the outlet alternately towards and away from each other, the interior volume of the pump chamber (1) being variable in correspondence with the relative distance between the inlet and the outlet. The pump chamber (1) is on its outside influenced by the surrounding pressure and has a wall of a flexible material constructed in such a manner that the pump chamber will collapse and reduce its volume, if the interior pressure in the pump falls below the surrounding pressure by an amount greater than the required opening pressure difference for the nomn-return valve connected to the inlet.
