There are described new immunomodulator peptides of the general formula R1-aa1-aa2-aa3-aa4-aa5-Pro-aa7-aa8-aa9-aa10-aa11-aa12-aa13-aa14-aa15-R2 in which R1 represents H, R2 represents OH, or else R1 and R2 represent each an amino acid residue or peptide chains, equal or different, containing from 2 to 10 amino acid residues, in such a way that when R1=H and R2=OH, the formula represents a pentadec...

An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction. This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded...

A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone ocnduction. The hearing is believed to use channels of communications to the brain that are not normally used for hearing. These alternative channels do not deteriorate significantly with age as does the...

A process on an open-end spinning rotor to produce core stretch yarn has staple fibre introduced to the rotor which is spun with an elastane base from a reel at the back of the rotor. This is unwound by tension rollers and fed into a passage coupled to the rotor, then the multicomponent yarn is drawn through another set of rollers, driven at a proportionately higher speed. ADVANTAGE - There is imp...
