  • Process and device for recognizing foreign bodies in viscous or fluid, lump-containing foodstuffs
    Patent number: 6324901
    Abstract: A process and device are disclosed for recognizing foreign bodies in viscous or fluid masses with lumpy foodstuffs. The mass to be checked runs through a measurement section, in which, pulsed ultrasonic signals are emitted through the mass, are reflected after passing through the mass, and after passing again through the mass they are received and compared with the ultrasonic echo of the reflection surface. When the changes of the received signals exceed a predetermined threshold value, a warning or actuating signal is generated to interrupt mass advance. The parameters to be evaluated for the signal may be their amplitudes, as well as the speed of change of their amplitudes or the propagation times.

  • N-[3-(1'-3"-O xapentamethylene-amino-ethylideneamino)-2,4,6-triiodobenzoyl]-.beta.-amin o-.alpha.- methylpropionitrile in process to make corresponding acid
    Patent number: 4375543
    Abstract: The present invention relates to the novel compound N-[3-(1'-3"-Oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.methylpropionitrile which due to the sparing solubility in water, can be purified readily in a simple manner and can be used for the preparation of the known active compound for agents for peroral rapid cholecystography N-[3-(1'-3"-oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.-methyl propionic acid.
