| 20080248433 | PHOTOGRAPHIC ELEMENT CONTAINING A SPEED-ENHANCING COMPOUND - The invention provides a colour photographic element comprising at least one light-sensitive silver halide emulsion layer or a non silver-containing light-insensitive layer, in which at least one of these layers contains a colourless imidazole compound of formula (I) that undergoes less than 10% chemical or redox reaction directly with oxidized developer and which has a partition coefficient to enable the photographic speed of the element to be increased by at least 0.03 stop without increasing granularity, compared to the same element without the compound, wherein the compound of formula: (I) has the structure: wherein X is H or a substituent; Z represents the atoms necessary to complete an unsubstituted or substituted imidazole ring, which may form part of a fused unsubstituted or substituted ring system containing no further ring heteroatoms; wherein there is present at least one —NH group either in the imidazole ring or directly attached to the imidazole ring as part of X; provided that (a) when Z represents the atoms necessary to complete an unsubstituted or substituted benzimidazole ring, an —NH group is directly attached to the imidazole ring as part of X, and X is located between the imidazole nitrogen atoms; (b) when the —N—H group is located in the ring adjacent to the carbon atom bearing X, and X is located between the imidazole nitrogen atoms, the imidazole ring is not fused to a phenanthrene ring. The compounds of formula (I) increase speed without a concomitant increase in size of the light-sensitive silver halide grains. | 10-09-2008 |

| 20110115355 | APPLIANCE DOOR - The present invention relates to a door for an appliance. The door has a front panel and a rear panel and edges extending between the front panel and rear panel to create an internal cavity between the front panel and the rear panel. A filler material is contained in the internal cavity, and an intermediate material is interposed between a rear surface of the front panel and the filler material. The intermediate material or front panel is adapted to retain the front panel relative to the filler material by a magnetic field and release a portion of the front panel relative to the filler material upon excessive localized deformation of the filler material. | 05-19-2011 |
