摘要:
A system and method for distributing digital copyright work having a copyright owner is described herein. The method comprises selecting, by a download customer, a digital copyright work for inquiry. A digital copyright work is associated with an advertising sponsor based on attributes at least partially selected by the advertising sponsor. Upon selection of said digital copyright work for download, the sponsoring advertiser is charged according to said attributes. The advertising sponsors is provided with the capability of full sponsorship or partial sponsoring. The association of digital copyright data with advertising sponsors is augmented by an analytical engine, which receives and aggregates data regarding rates of successful downloads, download charges paid by the download user, and other information. The digital copyright works may be music, movies, or graphics files that are typically downloaded onto a portable device, such as a cellular phone, portable music player, or personal digital assistant (PDA).

Disclosed are brushes for cleaning toilet bowls and the like. The brushes have a permanent handle and can be used with a replaceable/disposable brush head that is flushable after use. The brush is a stack of sheets of water-dissolvable material. The sheets are compressed to both bind them together into a stack and create axial/longitudinal undulations. A wand provides a remote system for clamping and unclamping the brush head. The wand has a jaw whose mouth has corresponding undulating configurations. A side opening in the jaw may also be provided to facilitate assembly, as may a rear catch portion on the brush head.

In an area to be monitored, first signaling information is deliberately emitted to synthetically create conditions which force the mobile radio terminals that are to be detected to transmit second signaling information as a reaction. The second signaling information is then processed in order to detect mobile radio terminals which are not switched off.

The invention provides compounds of formula I ##STR1## wherein X, Y, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined in the description, and a process for preparing them. The compounds of formula I are useful as pharmaceuticals.
摘要:
Compounds from the class consisting of the phthalocyanines, naphthalocyanines, the aminium compounds of aromatic amines, the methine dyes or the azulenesquaric acid dyes, which have their absorption maximum in the range from 600 to 1,200 nm and a fluorescence maximum in the range from 620 to 1,200 nm, are used as crack-detecting agents.
摘要:
Methine dyes of the formula ##STR1## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, X, Y and the rings A and B each have specific meanings, and methine dyes obtainable by reacting an organic mono- or polyisocyanate with such a methine dye of the abovementioned formal where only the radicals R.sup.1 and/and R.sup.4 have a group reacting with an organic mono- or polyisocyanate are useful in optical recording media.
摘要:
Azulenesquaric acid dyes of the formula ##STR1## where L is substituted or unsubstituted C.sub.1 -C.sub.12 - alkylene,R.sup.1 is C.sub.1 -C.sub.20 - alkyl, C.sub.5 -C.sub.7 - cycloalkyl or substituted or unsubstituted phenyl andR.sup.2, R.sup.3, and R.sup.5 are each independently of the others hydrogen or substituted or unsubstituted C.sub.1 -C.sub.12 -alkyl,with the proviso that when R.sup.5 is hydrogen the positions of the substituents CH.sub.2 --L--O--CO--NHR.sup.1 and R.sup.4 on an azulene ring may also be interchanged within a ring in either or both of the azulene rings, derived from azulene intermediates that contain urethane groups, are suitable for use in an optical recording medium.
摘要:
Bislactams of the general formula I ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another are each C.sub.1 -C.sub.4 -alkyl, or R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4 form a tetra- or pentamethylene radical, and R.sup.5 is hydrogen, carbonyl-C.sub.1 -C.sub.8 -alkyl, benzoyl, C.sub.1 -C.sub.8 -alkyl, C.sub.7 -C.sub.10 -phenylalkyl, the phenyl nucleus being unsubstituted or substituted by one or two C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkyoxy, fluorine, chlorine or bromine radicals, or is C.sub.1 -C.sub.3 -cyanoalkyl, C.sub.2 -C.sub.4 -hydroxyalkyl or C.sub.2 - or C.sub.3 -aminoalkyl, and the acid addition salts and hydrates of these compounds.The compounds (I) are stabilizers for organic materials.
