  • Lead sharpener
    Patent number: 4124048
    Abstract: A lead sharpener comprises a housing formed by relatively rotatable lower and upper housing portions containing a milling cutter of which the operating face extends at an acute angle to the longitudinal axis of a guide passage through which the lead that is to be sharpened is introduced. To enable the sharpened point of the lead to have a selected configuration, the guide passage is provided in an insert member which is rotatable in a hole provided in the upper housing portion, the arrangement being such that the longitudinal axis of the guide passage does not coincide with the rotary axis of the insert member whereby, upon rotation of the insert member, the spacing and possibly also the angle between the longitudinal axis of the guide passage and the operating face of the milling cutter are changed.

  • Process for preparing acrylic acid or methacrylic acid ester polymer having a high isotacticity and a narrow molecular weight distribution
    Patent number: 4124751
    Abstract: Esters of acrylic acid and methacrylic acid may be polymerized with the aid of either free radical forming or ionically effective initiators. The stereospecificy of the polymers may be influenced by the selection of specific initiators; magnesium-organic compounds are suitable for the synthesis of isotactic polymers. Acrylic acid and methacrylic acid esters having a high degree of isotacticity and a narrow molecular weight distribution are obtained with the aid of substituted phenylmagnesium halides. They are suitable as gauge and as test substances.
