Abstract: A process for finishing armoured resin products or thermoplastic resin products is characterized by applying on the surface of the resin product A at least one layer or sheet D of suitable heated thermoplastic material; applying to said layer D a pneumatic pressure to cause this to adhere integrally and evenly to the surface of the product; and cooling the whole so that, in contracting, said layer penetrates and secures itself firmly to the surface of the product. The process is particularly suitable for finishing protective helmets. <IMAGE>

Abstract: A press section of a paper machine comprises, in the direction of web run, at least three separate press nips for removing water from a web, the web passing between two fabrics in each of the three nips. Dewatering of the web takes place through both faces of the web at least in the first press nip which is formed between two open-faced press rolls. The second and third press nips are formed between an open-faced roll and one of an open-faced roll and a smooth-faced roll. According to the invention, the press section includes two upper fabrics and two lower fabrics, the first upper and lower fabrics in the direction of web run being water-receiving press fabrics, one of which constitutes a press fabric only in the first press nip, the other fabric constituting a press fabric both in the first and second press nips. One of the second upper and lower fabrics is a water-receiving press fabric, the other being a water-non-receiving transfer fabric adapted to receive minimal amounts of water, if any. The web is transferred on the transfer fabric after the third press nip as a closed draw into the drying section which follows the press section.

Abstract: Method of effecting zoning in wood with the aid of fungus cultures. The wood is pretreated by sterilizing it, setting a suitable moisture content and impregnating it. Impregnation with nutrients ensures that the fungi are sustained by the nutrients added and not by the wood. Special patterns can be achieved by using inhibitors. Pretreated wood is inoculated with one or more fungus cultures and stacked in sandwich fashion. An interlayer is inserted into the inoculated sandwich to produce the desired zoning pattern. Incubation is performed with controlled moisture contents and moisture gradients in the wood, as well as the composition of the gas phase, and may be carried out as a two-step process. The method is performed entirely or partially in a closed system.

Abstract: Until now, sound protection hoods or sound-insulation material have been used for noise attenuation. Both types have, however, the disadvantage that a heat build-up has occurred. The use of crystals brought no technically satisfactory solution, since these point-shaped sound sources effected cancellation of the sound only at the intermediate frequency points. It is the object of the invention to reduce or to compensate noise arising preferably in the case of electrical machines or devices. In this case, the sound-emitting body or the housing surrounding the body is enveloped in a film, known per se, made from a polymeric material. A signal of phase opposite to the sound waves is applied to this film, on the side facing away from the body. By means of this invention it is for the first time possible to provide sound-emitting bodies of large surface area with protection against sound or noise.
