Abstract: Fremgangsmåte for personsøking, hvori en første bruker (A) ønsker å søke etter og overføre en melding til en andre bruker (B) ved hjelp av en søketjeneste. Den første bruker (A) forespør om søking etter den andre bruker (B) ved en søke- sentral (1) som tilbyr en alerteringstjeneste og en meldingstjeneste som supplementerer alerte- ringen sammen med meldingen. Søkesentralen (1) alerterer den andre bruker (B) ved hjelp av alerteringstjenesten. Oppfinnelsen er kjenneteg- net ved at søketjenesten ikke har tilknytning til et spesielt telekommunikasjonsnett, men kan utføres i minst ett telekommunikasjonsnett (for eksempel i N1 og N5) utvalgt blandt minst to telekommunikasjonsnett (N1-N5). Meldingstjenes- ten blir også gjort uavhengig av alerterings- tjenesten, ved at meldingstjenesten ikke blir aktivisert før det blir mottatt en forespørsel om dette fra den andre bruker. Alerteringstjene- sten benytter nevnte første telekommunikasjons- nett (N1-N5) mens meldingstjeneten bruker minst ett telekommunikasjonsnett (N1-N5) som selektivt er forskjellig fra førstnevnte nett (NI og N5). Meldingen blir ikke sendt ut før nevnte fore- spørsel blir mottatt.

Abstract: A method of bonding powdered material to a surface comprising placing at least one layer of powdered material onto a support of ductile material, positioning a surface to be coated by the powdered material in facing spaced relation with the powdered material and placing an explosive charge on the support on the surface thereof opposite the powdered material. The explosive charge is then detonated to produce acceleration of the support and the powdered material thereon towards the surface to be coated to cause impact of the powdered material with the surface to be coated and welding thereof. The detonation of the explosive charge proceeds along the length of the charge to progressively bring the powdered material into impact contact with the surface to be coated. The speed of detonation of the explosive charge is less than the speed of sound in the powdered material or support.
