Abstract:
A jewelry ring re-sizer is disclosed. The re-sizer is roughly cylindrical in shape, and has an aperture extending longitudinally along the directrices of the cylinder for accommodating the ring. The re-sizer is thicker in the middle, and tapered to be thinner toward either end, thereby providing improved snugness.
Abstract:
A timepiece comprising a date display, comprising a date display assembly comprising a date ring, a first gearing assembly being meshingly coupled to the date ring for causing the rotation of the date ring; and a stepping motor comprising a rotor, wherein the rotor of the stepping motor is rotateable coupled to the at least one or more wheels of the first gearing assembly, wherein the rotation of the rotor causes the date ring to rotate; a date-keeping assembly operatively coupled to the date display assembly, comprising: at least a second gearing assembly comprising at least an hour wheel and a detection wheel assembly, wherein at least certain rotational increments of the detection wheel, and the clockwise or counterclockwise direction thereof, causes the rotor of the stepping motor to rotate so that the date ring can be rotated in one of a clockwise or counterclockwise direction; whereby the rotation of the hour wheel through a predetermined midnight position results in that the stepping motor causes the date ring to rotate a predetermined number of degrees, thereby advancing either in the forward or backward direction a displayed digit on the date ring representing a valid date. Methodologies for setting and adjustment are also provided.
Abstract:
A timing device for visually indicating the passage of a duration of time is disclosed. The timing device and system, in accordance with the embodiments of the invention, is sectioned into zones with different rates of reactivity and/or sensitivity, such that the zones change color or darken over a range of times. The timing device, in accordance with further embodiments of the invention, comprises a film, that is a color film, a black and white film or a combination thereof, with a photographic layer and a developer layer, which when brought together activate the device. The photographic film can be pre-exposed to light or heat to control the rate that the film changes color or darkens after being activated. Pieces of timing film, in accordance with further embodiments of the invention, have adhesion layers for attaching the pieces of timing film to perishable articles or packages containing perishable articles and are preferably configured to be dispensed from a roll or stack of the timing film.
