Patent DE-19645240-A1 (DE)
Inventor: JONAS GERD DR
IPC: B65D81/26
Filed: 1996-11-02
Abstract: The invention concerns an absorbent insert for food packaging, the liquid-absorbing component of the insert being a superabsorbent polymer which, even at high pressure loads, can permanently absorb and hold large amounts of liquid in a previously unattainable manner, protects the food from bacterial attack, and prevents the packaged goods from contamination by migrating soluble constituents of the polymer. This combination of properties of the superabsorbent used is expressed by the quotient QSAP 0.3 from the equation: retention after the tea-bag test plus absorption against pressure (AAP) at 0.3 psi divided by the amount of soluble parts, the quotient being at least 20. Superabsorbents with properties of this type are obtained by using special crosslinking agent combinations. The invention further concerns a method of producing these inserts and their use in food packaging, as an ice-substitute and for protection against leakage in packaging for transport purposes.

Patent DE-19654053-A1 (DE)
Title: Ultrasonic determination of optical characteristics in biological tissue
IPC: G01N29/24
Filed: 1996-12-23
Abstract: A process for determining the local physical and chemical characteristics in biological tissue or in turbid liquids uses ultrasound to modulate simultaneous electromagnetic waves, preferably in the range of visible light, and to change optical characteristics. The ultrasound modulates amplitude and/or frequency. Light interacting with the substance under investigation not only reveals its characteristics but changes by interaction with the sound field. By the use of an appropriate filter, the emergent light from the tissue is separated into the modulated and non-modulated. The process improves local resolution and permits better determination of the optical characteristics of the material, both in quantitative and in qualitative analysis. The system is particularly useful in medical diagnosis, such as mammography.
