Abstract: In the manufacture of multi-layer printed-circuit boards having rigid and flexible regions, either only rigid layers, with a maximum thickness of 0.1 mm are used, or, in the case of thicker rigid layers, after non-electrical metallizing, the flexible regions are electrically insulated by strip-shaped material coating in the rigid- flexible boundary region and slotting between flexible regions and parts to be separated, so that either the galvanic covering (Riston foil) of the rigid-flexible step is not damaged or any tearing of the galvanic covering remains inconsequential, as a consequence of the island structure in the flexible region and outlet openings for the bath fluids are moreover produced to this end. <IMAGE>

Abstract: A method and apparatus for controlling the density of dispensed hot melt thermoplastic adhesive foam in order to assure uniform foam characteristics. In order to create the hot melt adhesive foam, air or any relatively inert gas is mixed with the thermoplastic adhesive while the adhesive is in the molten state, and the mixture is then pressurised so as to force the gas into solution with the molten adhesive. As the molten adhesive/gas solution is dispensed at atmospheric pressure, the gas is released from solution and becomes entrapped in the adhesive so as to form a homogenous closed cellular adhesive foam. According to the invention, the supply of gas is periodically discontinued so as to prevent an excess volume of gas from being admixed with the molten adhesive whenever foamed adhesive is not being dispensed, thereby stabilising the density of the adhesive foam.

Abstract: In an article suitable for wiping surfaces which comprises an elongate web substrate impregnated with a liquid composition, migration of the liquid along the length of the substrate is substantially prevented by dividing the substrate into a plurality of individual areas by means of a repeating pattern of liquid- repellent barrier material, for example, wax or certain resins, extending across the whole width of the substrate. This measure prevents fluid loss by capillary action and evaporation when the wet substrate is stored in a dispenser. The wet substrate is preferably used in conjunction with a dispenser having a relatively tight closure, especially one in which the closure is formed by two resilient diaphragms with out-of-register apertures. The wet substrate delivery system may be used, for example, for hand hygiene in hospitals, washrooms or kitchens.

Abstract: The invention is concerned with a method and a mould in continuous slide-casting of large-size concrete objects or corresponding elements for compacting high-viscosity casting mix. The slide-casting mould (33) comprises a bottom plane (34), side walls (38,39) of the mould, as well as means (37) for pressurizing the casting mix mechanically. According to the invention, before the parallel side walls (44, 54) at the outlet end of the slide-casting mould (33), within the casting line concerned, walls or wall portions (40 to 43, 50 to 53) are provided as fitted to each other or to their corresponding portions, provided as pairs, as pivotable always in the same direction around substantially vertical shafts (45 to 49, 55 to 59) included in their planes. The moving parts of the side walls (38, 39) may be displaced in pairs in the lateral direction, relative the casting direction, e.g., by means of cylinder-piston devices (61 to 63). Thereat, repeated parallel dislocations back and forth are produced in the various regional zones of the mechanically pressurized high-viscosity casting mix (35) present in the slide-casting mould (33), and in particular in parallel dislocation planes of casting mix (35) in the mould (33), placed perpendicularly to the longitudinal direction of the casting base.

Abstract: In a centrifuge sieve drum, wherein the inner surface of the drum is lined with a support arrangement carrying wear-resistant sieve or screen rods, there is obtained a compensation of the different thermal expansions of the sieve rods and the support arrangement in that, the sieve rods comprise an axially extending web and the support arrangement comprises identically shaped grooves or slots engaged by the webs. Each web and its associated groove or slot may be designed, for example, as a dovetail guide. Thus, while the sieve rods may expand or contract in longitudinal direction or in the direction of the lengthwise axis of the drum, the sieve rods are, however, immovable in radial direction and in circumferential direction. Such a support arrangement can be efficiently manufactured by simultaneously cutting, such as by milling the grooves or slots and sieve openings or slots in a convex outer surface using a triple cutter, such as a milling cutter, and by subsequently bending the supporting arrangement to form a concave surface and inserting the same into the drum.

Abstract: A method and a repeating instrument are provided for applying a plurality of ligating clips seriatim. Handles are provided for closing a pair of jaws which are normally biased to an open position. A circular magazine is mounted for rotation on the instrument behind the jaws and holds a plurality of clips in a spaced-apart circular array. A flexible pusher member is provided for pushing a clip out of the magazine and into the jaws when the handles are dosed. The flexible pusher member is wound on a wheel which is driven by a gear engaged with a gear segment on one of the handles of the instrument. Partial closure of the handles initially withdraws a flexible pusher member from the jaws. Subsequent further closure of the handles acts through a ratchet and pawl mechanism to rotate the magazine to present a new clip in position behind the jaws and in front of the retracted flexible pusher member. At the same time, the jaws of the instrument are squeezed to latch the clip closed about tissue. Subsequent opening of the handles causes the flexible pusher member to be advanced from the magazine to position the new open clip at the jaws.
