  • Patent number: 5350612
    Abstract: A multi-ply, wet-strength, removable label or coupon for packages intended for retail use, particularly suitable for items where refrigeration and/or condensation is a condition of the product life cycle. The coupon structure includes a base ply formed of moisture resistant, wet-strength paper with printable or coatable upper and under sides. The base ply is adhered to a removable top ply with a combination of bonding agents and release coatings. The top ply may also be moisture resistant.

  • Patent number: 4109647
    Abstract: An apparatus for measuring the flow parameter of blood flowing in an organ includes a laser and associated optics which effect the illumination of tissues. The laser light, scattered by the tissues, emerges with a spectrum broadened by Doppler effect due to motion of red blood cells in the micro-circulation vessels. The light from the tissues is fed to a photomultiplier tube or photodiode via a pinhole mask and interference filter. The photomultiplier tube or photodiode, as a result of beating of various components of the light it receives, produces as its output signals a homodyne or heterodyne spectrum or both. These output signals are fed, via a low pass filter, to a differentiator, which differentiates the output signals from the multiplier tube or photodiode, which are passed by the filter, with respect to time. The output of the differentiator is fed to a root-mean-square (RMS) detector. The low pass filter passes, for example, signals having a frequency up to about 20 KHz.
