Abstract: The typing arrangement includes a character-bearing member of the "daisy wheel" type, the symbols of which can be printed at the point of printing either alone or in the form of combinations of successive strikes of certain symbols for constituting a font of printable characters and other symbols which is appreciably greater than the number of symbols on the daisy wheel, and adapted to meet the printing requirements of all the graphical symbols derived from one common alphabetical stem. Each printable character has an individual code which is recognizable by the control circuits of the arrangement which put into operation one or several printing cycles using selection of the symbol or of the symbols on the daisy wheel which make up the character and the displacements of the daisy wheel associated with the printing of the various component symbols.

Abstract: Glass having improved hydrolytic and chemical resistance as well as improved water repellency and mechanical characteristics is obtained by reacting the glass surface with an organoborosiloxane polymer, substituted by one or more of alkyl, aryl, alkoxy, acyl radicals, said organoborosiloxane polymer containing no free hydroxy groups in the presence of one or more organic Ti, Zr, Sn, v compounds at a temperature comprised between 200.degree. and 400.degree.C in order to obtain, through a grafting reaction, a superficial layer of modified glass.
