Abstract: Aqueous alkaline sulfidic waste effluents are often subjected to air oxidation processes that for economic sizing oxidise the sulfides only to thiosulfates. Thiosulfates are still immediate oxygen demanders and thus their concentration in the effluent must normally be reduced to below a threshold level before the effluent can be discharged. The effectiveness of hydrogen peroxide for this purpose can be significantly improved both as to rate of reaction and extent of removal by employing a coppper catalyst in solution.

Abstract: The invention relates to a new vaccine comprising a native protein capable of inducing the production of protective antibodies in a host, together with an adjuvant amount of certain proteins or peptides which, as such, are not capable of inducing substantial protective antibody titres but considerably enhance the immunizing activity of said native protein. The amino acid sequences of the adjuvant proteins and peptides show homology with the native proteins. Combination of inactivated picornavirus, such as poliovirus, with adjuvant amounts of denatured picornavirus, such as poliovirus, capsid proteins, in a vaccine, is highly advantageous.

Abstract: A method for introducing gas like oxygen, air or carbon dioxide into water, in which a water flow enriched in the gas is passed through a reaction chamber so that the flow rotates around and moves along the longitudinal axis, a sudden pressure minimum is provided in a section of this axis where gas comprised in the flow gets collected and mixed with vapor, the pressure is increased after the minimum, whereby gas is swallowed by water so that gas molecules get bound to water molecules. The apparatus for carrying out the method comprises a closed recirculating path with the reaction chamber (15), the flow is maintained by a pump (14), and the gas is introduced in the water either by a vortex stream or by a water jet pump. The so obtained water comprises the gas in stable and bound state in a concentration exceeding normal saturation. The dielectric constant and certain physical parameters of such water differ from those of pure water.

Abstract: A concertina structure between two flexibly connected tracked or other road vehicles is made of a polymer-coated fabric, the cross-linking of the polymer being changed partially or irreversibly by the input of energy (e.g. by irradiation). The material is pref. irradiated with electrons or X-rays; the treatment can be attuned to make relative hard polymers softer or vice versa. If the material is rendered stiffer, the sides of the concertina structure can be used vertically without needing a mechanical support. On the other hand where flexibility is desirable the material can be treated accordingly, to have max. service life.

Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.
