Abstract: An electrical cord which comprises electrical conductors bundled together and electrically insulated from one another to prevent shorting therebetween and having an outer body applied around the cord. The outer body has a series of sections that sequentially follow one another along a length dimension of the cord, with each section comprising a body material that is sufficiently rigid to prevent the body material from being bent by a child during normal use or play. The cord is bendable between the rigid sections.

Abstract: Novel non-elastomeric biomedical adhesive compositions for calcified tissues, are described. The compositions are characterized by a network structure which is obtained by the reaction of a polyisocyanate having at least two isocyanate groups with at least one polyol which possesses surface wetting properties with the participation of compounds selected from calcium and phosphorus, optional in the presence of a catalyst. The polyisocyanate is selected from aliphatic, alicyclic and aromatic compounds and preferred amounts are in the range of 20% to 80% by weight of the total amount of reactants. The polyol is selected from polyalkylene ether glycols and polyester glycols containing between 25 to 75 carbon atoms and preferred amounts are in the range of 10% to 80% by weight of the total amount of reactants. The adhesive compositions were found to produce a fast bonding of the calcified tissues, with a joint strength of above 0.5 N/sq.mm.
