    摘要： A microporous powder form polylactide which can take up a multiple of its own weight of active material and which can be used for the controlled release of that active material. The aforesaid microporous polylactide powder can be prepared by dissolving polylactide under warming in phthalicacid diethylester, preferably at a temperature over 150.degree. C. and then slowly cooling the clear solution. The resulting suspension is then subjected to filtering and any remain phthalicacid diethylester preferably removed by extraction. The microporous powder recovered is especially suitable for applying thereto therapeutically active substances for controlled release therefrom and is particularly suitable for utilization in veterinary and human medicine. The microporous powder in this form can be introduced into the body subcutaneously, intramuscularly and intraperitoneally.

    摘要： Process and apparatus for enriching liquids with oxygen by means of a catalyst and a liquid which gives off oxygen under the effect of that catalyst. The process involves passing the oxygen-yielding liquid through a porous molding, in the pores of which the catalyst is incorporated in known manner, thereby giving off oxygen, the side of the porous molding which gives off a greater quantity of oxygen being in contact with the liquid to be enriched with oxygen. The oxygen-yielding liquid is passed through the porous molding under its own static pressure, or under the effect of the excess pressure built up in the container through the formation of oxygen. Preferred embodiments include use of a 0.1 to 5% solution of hydrogen peroxide as the oxygen-yielding liquid; using ruthenium oxide or hydroxide as the catalyst. The apparatus for carrying out the process includes a storage vessel containing the liquid which gives off oxygen under the effect of a catalyst, connecting means, and a porous molding connected thereby to the storage vessel and containing the catalyst, the molding being completely immersible in the liquid to be enriched with oxygen. Alternatively, the storage vessel and the porous molding can be dipped into the liquid to be enriched with oxygen, so that at least the entire molding is immersed. Preferred embodiments include the porous molding being a tube having at least one empty space extending over its entire length, one end tightly sealed and the other end tightly connected to the storage vessel; the porous molding being a hollow body having an empty space with an internal diameter of at least 0.5 mm extending over its entire length; the porous molding being of polypropylene, MgO, Al.sub.2 O.sub.3 or clay; use of a metering pump for adjusting the supply of oxygen-yielding liquid; and provision of a vent connected to the porous molding.

    摘要： A fastener for securing an undercover panel to an underside of a vehicle is disclosed. The fastener includes a body having a bore for receiving a threaded bolt extending from the underside of the vehicle, a flange for engaging a first side of the undercover panel, a plurality of resiliently deformable engaging fingers for allowing insertion of the bolt into the bore and to resist removal of the bolt from the bore, and a plurality of resilient engaging members for enabling the engaging members to pass in a first direction through an aperture in the undercover panel, and to resist removal of the fastener from the panel. A plurality of reinforcing members extend from the body to engage a respective engaging member, as a result of forces urging said undercover panel towards the underside of the vehicle, to resist flexing of the engaging members away from the body.
