Technical Examples
- An interactive binder and platform system includes a remote multimedia source, a feedback unit electronically connected to the remote multimedia source, and a plurality of binders. Each binder includes a plurality of conductive pins and at least one fixed medium having a plurality of distinct circuits operatively connected to the binder and a plurality of touch points defining exposed portions of the distinct circuits. A transceiver electronically connected to at least one of the binders provides power to the at least one of the binders and transmits/receives signals to provide two-way communication between the remote multimedia source and the binders where selection of a particular touch point by a user electronically connects the distinct circuit associated with the particular touch point and the remote multimedia source, the output from the remote multimedia source associated with input sent to the remote media source by the selection of the particular touch point.
- Compounds of Formula (I), and their N-oxides and suitable slats, are disclosed which are useful as invertebrate pest control agents, wherein A and B are independently O or S; E is C or N; J is a phenyl ring, a naphthyl ring system, a 5- or 6-membered heteroaromatic ring or an aromatic 8-, 9- or 10-membered fused heterobicyclic ring system wherein each ring or ring system is optionally substituted with 1 to 4 R
- An undersea hydraulic coupling member having a seal retainer with a first inner ring and a second outer ring is disclosed. The first inner ring and second outer ring are concentric, at least part of the first inner ring inserted through the second outer ring. The second outer ring is threaded to the coupling member to provide sufficient torque to reduce or eliminate any gap between the seal retainer and the shoulder surface in the coupling member on which an elastomeric seal is positioned. Another elastomeric seal is held between the first inner ring and second outer ring of the seal retainer.
- A fitting for liquid or steam piping, comprising: an elastic sealing ring; a locating sleeve placed around said sealing ring; an internal teethed lock ring located on the locating ring outer end face; an inner ring located outside of the internal teethed lock ring, the inner surface of the inner ring matching with the outer surface of the pipe to be coupled, the inner ring further including a tapered surface and external threads on the outer surface of the inner ring; an outer ring with threads on its internal surface for matching the external thread on said inner ring, as well as methods for connecting pipes using the fitting.
- The invention relates to a process for the production of di- and polyisocyanates of the diphenylmethane series and mixtures thereof, in which aniline and formaldehyde are reacted in the presence of an acid catalyst to form di- and polyamines of the diphenylmethane series; the di- and polyamines of the diphenylmethane series are phosgenated, optionally in the presence of a solvent, to obtain a crude di- and polyisocyanate; from the crude di- and polyisocyanate, at least one fraction containing at least 5 wt. % 3-ring and multi-ring MDI and at least one fraction containing at least 95 wt. % 2-ring MDI are separated by distillation, and the acidities of the fraction containing at least 5 wt. % 3-ring MDI and multi-ring MDI, and/or the fraction containing at least 95 wt. % 2-ring MDI are determined analytically; and an acidic compound is added to the fraction containing at least 5 wt. % 3-ring MDI and multi-ring MDI, and/or the fraction containing at least 95 wt. % 2-ring MDI, so that the desired acidity is achieved.
