Patent EP-0003194-A1 (EP)
Inventor: TROTTER JIMMY RAY
IPC: C09J7/02
Filed: 1979-01-05
Abstract: This invention relates to blends of plasticizing oils and compatible tackifying resins with substantially amorphous or semicrystalline olefin copolymers containing a C 3  to C 5 linear a-olefin and 15 to 60 mole percent of a C 6  to C 10  linear a-olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer base resins have melt viscosities in the range of 5,000 cp up to 1,000,000 cp at 190°C. The addition of the plasticizing oils and compatible tackifying resins to the copolymer base resin causes an unexpected increase in the shear adhesion failure time in addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.

Abstract: Stationary heat transfer coefficient fields are made visible by applying a swelled photographic film (original wet film) in daylight to the article to be exposed to the flow. The wet film obtained after it is exposed to a gas flow and removed from the article, is squeezed onto an unexposed dry photographic film. The separated wet copy (latent image) is seeded with reactive gas (H2S) to make the moisture profile visible, and is developed into a wet-copy photogram (black-and-white picture), the sharp contours of which (line equidensities, isohumids) can optionally be translated into colors, corresponding to the stationary mass transfer distribution, and with which definite heat transfer coefficients can thereby be correlated.

Abstract: A process for the accurately timed registration of mineshaft signals and operating conditions of the conveyor in mineshaft installations is distinguished in that the given mineshaft signals, any change in an operating condition and the path of travel with direction recognition with an indication of the date and time, are expressed to an accuracy of the order of the second on a single registration strip. For improved temporal resolution and registration of a plurality of signals or changes to operating conditions which occur at short intervals or almost simultaneously and which are independent of one another, the speed of advance of the registration strip is increased from a normal value to a suitable value and the printing speed is increased. The registration device is operated with the supply voltage for the mineshaft signal installation or switched over automatically to accumulator supply for the built-in quartz clock, if the supply voltage fails, so that the start and end of a period of power supply failure are also recorded. <IMAGE>

Abstract: A non-destructive thermal imaging method for detecting the presence of a liquid such as water within a sealed container (10). The process includes application of a low amplitude heat pulse to an exterior surface area of the container, terminating the heat input and quickly mapping the resulting surface temperatures. The various mapped temperature values can be compared with those known to be normal for the container material and substances in contact. The mapped temperature values show up in different shades of light or darkness that denote different physical substances. The different substances can be determined by direct observation or by comparison with known standards. In the past, destructive testing methods have been used which were slow and resulted in exposed solid waste that must be re-contained prior to disposal. The non-destructive method permits quick and accurate detection of the presence of free liquid in sealed containers.
