A cellular telephone access control, identification, and intruder alarm activation and deactivation system (15) that uses transmitters which generate a dual tone, multi-frequency (DTMF) modulated signal. Thus, persons who have standard portable, cellular or mobile telephone can use the telephone to obtain access to controlled areas and/or to activate and deactivate home or commercial building alar...

Rigid foams containing urethane groups and predominantly isocyanurate groups are obtained by reaction of 1) polyisocyanates with 2) compounds containing at least two isocyanate-reactive hydrogen atoms and having a molecular weight of 400 to 10,000 in the presence of 3) organic blowing agents and 4) flameproofing agents and 5) compounds containing at least two isocyanate-reactive hydrogen atoms and...

Reticulated polymer foams permitting a through and return flow of gasses have many uses, such as in conventional filters and 'heat and moisture exchange' devices. The thermal capacity of these foams is relatively low in comparison to other materials such as metals. In order to increase the efficiency of foams when used in HME's this invention provides for the incorporation of a filler material, su...

A method of removing the binder phase from the surface of a hard material body consisting of hard constituents in a binder phase based on cobalt and/or nickel and with a binder phase enriched surface zone is disclosed. By carrying out a blasting process using particles with a size of 400-1500 mesh, a favorable combination of even removal of the cobalt layer, essentially no damage to the carbide gr...
