This invention relates to noncaloric saccharine artificial sweetening compositions, and more particularly to sweetening compositions which are free of cyclamate, contain only saccharine as the artificial sweetener, but which contain additives which do not add calories but nevertheless eliminate the undesired bitter aftertaste of the saccharine. The additives which are used according to this invention, and which must be used in combination because the only sweetening agent is saccharine, are gluc...

The present invention relates to a free-wheel constituting a one-way coupling device and comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to co-operate with said jamming members, a synchronization cage for housing said jamming members, said cage being subjected to an elastic restoring action, and two lateral closure ring...

The instant invention is directed to the production of essentially lead-free and cadmium-free frits which are eminently suitable for the production of decorative glazes and enamels to be used with glass, glass-ceramic, and ceramic articles. The frits exhibit good glass stability, demonstrate coefficient of thermal expansion (20.degree.-300.degree. C.) between about 52-65.times.10.sup.-7 /.degree.C., display excellent resistance to attack by acids and bases, and can be fired to fusion at temperat...

This invention is related to the production of glazes and enamels for decorating glass, glass-ceramic, and ceramic articles. The glass frits suitable therefor exhibit good glass stability, coefficients of thermal expansion (20.degree.-300.degree. C.) between about 65-75.times.10.sup.-7 /.degree.C., demonstrate excellent resistance to attack by acids and bases, and, being essentially free from toxic heavy metals such as lead, are eminently useful in food preparation and service applications. The ...

Novel triarylmethyl free radicals, their use as image enhancing agents in MRI, in particular to their use in Overhauser enhanced MRI of a sample for determining oxygen concentration of said sample.

A power and free conveyor system is provided which utilizes a difference in height between the wipe in power trolley and the wipe out power trolley, with or without a camming down of a retractable wide dog of the free trolley, to allow the wipe in power chain to wipe in over the retractable dog without any possibility of lateral interference. Thereafter the elevation of the wipe in power trolley and the wipe out power trolley are the same. Improved stop means operating to push down the retractab...

The present invention relates to certain novel triaryl methyl free radicals and their use as image enhancing agents in magnetic resonance imaging (MRI) as well as to contrast media containing such radicals and to the use of such radicals and their non-radical precursors in the manufacture of MRI contrast media.

The invention provides novel persistent free radicals useful in Overhauser MRI being triarylmethyl radicals having as at least one aryl group a group of formula ##STR1## (wherein each X which may be the same or different is an oxygen or sulphur atom or a group CO or S(O).sub.n, (where n is 1 to 3) with the proviso that at least one group X is a sulphur atom or a S(O).sub.n group; R.sup.1 is a hydrogen atom or group of formula --M, --XM, --X--Ar.sup.2, or --Ar.sup.2 where M is a water solubilizin...

The present invention is concerned with improvements in free-wheel mechanisms adapted to couple together or to disconnect two members capable of relative rotation. The free-wheel mechanism is intended to cooperate with two circular tracks, an inner track and an outer track, one of said tracks comprising ramp means, a plurality of jamming members such as rollers, an assembly cage for said jamming members, said cage having a circular series of windows adapted to receive said jamming members, elast...
