  • Publication number: 20240100296
    Abstract: A package for a medical device such as an intermittent catheter has a case and a cap connected by threads. The case includes a hollow tube which is closed at one end and open at the other. A shoulder is formed near one end of the case. Above the shoulder is a cylindrical ferrule that includes external threads. The cap has internal threads selectably engageable with the threads on the ferrule to form a liquid-tight seal between the cap and case when the cap is installed on the case.

  • Patent number: 4855074
    Abstract: A homogeneous concentrate suitable for use as an additive for lubricating oils is formed from a long chain succinimide and a benzotriazole by heating a mixture of these materials in the presence of water or alkoxylated amines or dihydrocarbylphosphites or dihydrocarbyl phosphonates (or mixtures of such materials) and then distilling the volatile component, from the resulting product. When this heating step is conducted in the additional presence of a boronating agent such as boric acid and the volatile component, is removed by distillation, not only is a compatible additive concentrate formed, but the long chain succinimide is boronated in the process.

  • Patent number: 4448974
    Abstract: A lubricating oil dispersant made by reacting an aldehyde (e.g. isobutyraldehyde) with an amine (e.g. tetraethylenepentamine) under conditions to form a Schiff base which is then reacted with a hydrocarbon-substituted succinic acid, anhydride or lower alkyl ester.

  • Patent number: 4331545
    Abstract: Friction of internal combustion engines is reduced by adding to the lubricating oil or fuel used in such engine a minor amount of a friction-reducing additive. The additive is the reaction product of a N-alkanol hydrocarbylamide such as N-ethanol oleamide with a boron compound such as boric acid.

  • Patent number: 4147640
    Abstract: Lubricating oils having improved antioxidant and antiwear properties are obtained by adding a minor amount of a reaction product made by reacting an olefinic hydrocarbon containing about 6-18 carbon atoms and about 1-3 olefinic double bonds concurrently with sulfur and hydrogen sulfide to obtain a reaction intermediate and reacting this intermediate with additional olefin hydrocarbon which may be the same or different.
