Abstract: The invention relates to a method for prophylactic treatment in order to eliminate the formation of tromboses and embolis in deep veins after surgical incisions in lower body regions, whereby a local anesthetic compound of the group consisting of lidocaine, mepivacaine, bupivacaine, tocainide, prilocaine, and ethidocaine is administered, as well as pharmaceutical preparations herefore.

Abstract: A process for the production of electroplated aluminium stock, such as strip or wire, comprises passing the stock continuously through a bath having a high dissolving power for aluminium oxide, such as strong aqueous sulphuric acid and phosphoric acid and subsequently through an electroplating bath, the first bath having a cathode electrode and the electroplating bath having an anode electrode so that the stock is anodic in the first bath. The stock may pass through one or more intermediate non-electrolytic treatment stages, such as immersion tinning or zincating. It may also pass through one or more electrolytic pretreatment stages during its passage between the first bath and the electroplating bath. In such pretreatment stages, such as the application of a bronze strike, there may be an anode electrode at the same potential as the anode in the electroplating bath.

Abstract: A mixture of powdered aluminum brazing alloy and a powdered flux consisting essentially of potassium fluoaluminate complexes is applied, in an aqueous vehicle, to aluminum surfaces which are to be joined, and the surfaces are then heated to brazing temperature while being maintained in juxtaposed relation to produce a brazed joint.
