Abstract
A clock comprising concentric rings of slots slits for indicating time by fully illuminating an appropriate one of the slots. Full illumination is propagated from one slot to an adjacent slot by causing all of the slots in a ring of slots to briefly light up sequentially, thus causing a flash of light to propagate around the ring of slots, thus more clearly showing passage of a second, a minute et as the illumination was switched from the one slot to the adjacent slot.
Claims57
A clock comprising a static surface with a number of narrow apertures, each corresponding to a representation of an instant of time in a predetermined unit, and a rotatable shutter with a number of narrow apertures arranged so that light propagating through a selected one of the apertures in the rotatable shutter can also propagate through one of the apertures in the static surface so as to indicate said instant of time;
- wherein the number of apertures in the rotatable shutter differs from the number of apertures in the static surface;
- and
- further comprising means for rotating the rotatable shutter from a position in which said one of the apertures in the rotatable shutter is in alignment with one of the apertures in the static surface to a position in which the same one of the apertures in the rotatable shutter is in alignment with an adjacent one of the apertures in the static surface when incrementing the instant of time indicated by one unit.
(canceled)
A clock comprising a static surface with a number of apertures each corresponding to a representation of an instant of time in a predetermined unit, and a rotatable shutter with a number of apertures arranged so that light propagating through at least one of the apertures in the shutter can also propagate through one of the apertures in the static surface;
- wherein the rotatable shutter is arranged to perform one full rotation in a period defined by the number of apertures in the static surface displaying the unit of time multiplied by the unit of time associated with the apertures in the static surface;
- and
- wherein the number of apertures in the static surface differs from the number of apertures in the rotatable shutter.
A clock comprising an escapewheel, a pair of pallets and a pallet carrier, wherein the pallets are arranged to, in use, be positively driven into and out of alignment with the escapewheel.
43-50. (canceled)
A clock comprising a motor arranged to rotate pallets, and a pallet controlled escapement driven by the motor continuously, in use;
- wherein the escapement is, in use, intermittently prevented from rotating by the pallets;
- the clock further comprising an energy storage device arranged between the motor and the escapement arranged to, in use, sequentially store driving energy produced by the motor and release said energy to drive the escapement.
52-55. (canceled)
A clock comprising means for running the clock at least first and second, different speeds.
57-61. (canceled)
A clock having a pallet controlled escapement wheel comprising means by which the sound caused by an escapement wheel tooth contacting a pallet face can be changed whilst the clock is running.
63-66. (canceled)
A clock having an escapement mechanism wherein an escapewheel is arranged radially outside a clock face and extends around a majority of a periphery of the clock.
68-72. (canceled)
A clock having a striking mechanism which is operative only when the clock is being run backwards.
74-77. (canceled)
A clock having an escapement mechanism driven by a first motor and a pendulum driven by a second motor.
79-80. (canceled)
A clock whose motion is controllable interactively by an observer.
82-84. (canceled)
