A heat-curable adhesive composition comprising a mixture of substantially solid particles of a first reactive component with separate substantially solid particles of at least a second reactive component, the first and second reactive components being capable of reacting together to effect curing when the composition is heated to the curing temperature and the particles having a size distributuion...

A sound wave receiving device associated with a probe lowered into a well at the end of a cable and applied against the wall of the well by opening anchorage arms. In the part of the probe in contact with the wall of the well there is disposed at least one receiver assembly comprising a sensor case connected by a resilient sheath and a sleeve, movable along a cylinder integral with the body, to th...

Steviosides can be obtained from dried material from Stevia rebaudiana Bertoni plants by extraction and purification, where an extract is obtained by treatment in water at a temperature from room temperature to about 65 DEG C and with stirring and subsequent filtration or centrifugation and is treated with calcium hydroxide, after which a precipitate is obtained by filtration or centrifugation and...

There are disclosed certain 6-piperazino-purine and heteroaromatic derivatives thereof which have oral hypoglycemic activity and with such ability to lower blood sugar are useful in the treatment of type II diabetes and/or obesity with associated insulin resistance. Processes for the preparation of such compounds and compositions containing such compounds as the active ingredient thereof are also ...

A softened, absorbent, composite structure is provided which structure is comprised of a fibrous web containing at least about 200 percent by weight of superabsorbent and containing a wicking layer subjected to microcorrugating in at least one direction and perf-embossing to yield an absorbent composite structure having a Taber stiffness value less than about 25, preferably less than about 10.
