  • Patent number: 9547281
    Abstract: An electronic interval timer in a dodecahedron case is described. The timer is set by turning uppermost one of 11 faces; and reset by turning uppermost the 12th face. In one embodiment, the timer is free of buttons, knobs, springs, time displays, electronic visual indicators and openings in the case. Time interval completion is announced via audible tones or speech. An aggregate time interval may be set equal to the sum of legends on more than one face. The timer detects carrying such that a running time interval is not modified. The timer may be programmed via a sequence of uppermost sides. Modes may be selected via shaking or tapping. Time remaining may be announced, an interval cleared, or an interval restarted responsive to detected motion. Other polyhedral shapes may be used. Claims include a method of setting a time interval; and specific ordering of face legends.

  • Patent number: 6799885
    Abstract: The method of dramatically speeding up the time it takes for sand, mercury, or water, or other like substances to flow from the upper compartment to the lower compartment of an hour-glass, usually in an hour but not specifically required in this method, entails the use of a premolded clear flexible polymer or any component similar, with the same flexibility properties, molded in the basic shape of an hour-glass, in which one can open the flow canal, which is a hole located in the center of the hour-glass, through the application of applying pressure directly to the above said flexible premolded polymer shape. The process of flexing this premolded form will permit the sand or other like substance to run between the upper and lower compartments of the hour-glass, allowing the above said substances to run through a wider and larger flow canal, from the upper compartment to the lower compartment. Thus, making the hour-glass work more efficiently.

  • Patent number: 5528561
    Abstract: A color-changing, position-reversible hourglass assembly having two transparent bulbs one above the other and a storage compartment adjacent each bulb, the bulbs and compartments being joined together by a neck. Intercoupling the bulbs and the compartments is a crossover network which passes through the neck to couple each bulb to the compartment adjacent the other bulb. In operation, when one bulb and its adjacent compartment are in an up position and are respectively loaded with sand of different color, then sand of one color appears to trickle from the up bulb into the compartment in the down position while sand of another color appears to trickle from the up compartment into the down bulb. The resultant apparent flow of sand from a higher to a lower level creates the illusion that sand flowing out of the up bulb is undergoing a color transformation as it flows into the down bulb.

    Abstract: An elapsed time indicator can easily indicate time periods of over a month, and is extremely versatile, for example being utilizable in a cap of a water bottle. The indicator includes a substantially transparent and substantially straight tube having first and second ends, an interior and an exterior, with a viscous liquid substantially filling the interior of the tube. A visible indicator, such as a polypropylene spherical bead, a magnetite/wax bead, or a fluid immiscible in the viscous liquid, is immersed in the viscous liquid and dimensioned and positioned with respect to the tube so that it can travel from the first to the second end in a known predetermined period of time when the tube is generally vertical. The time it takes for travel may be precisely calculated. The indicator may be held in a stationary position at one end of the tube, e.g. by clamping a flexible tube end, or using a magnet, prior to initial use.

  • Patent number: 5117405
    Abstract: A one-piece, quickly resettable gravity-flow timer consisting of a sealed container which integrally houses a base at one end and a reset reservoir at the other and, intermediate these, a receptacle, having a loading orifice nearest the reservoir and a metering orifice nearest the base. The receptacle is partially defined by indentations fo the container in such a way that all flowable medium in the base is instantly directed around the sides of the receptacle, through return channels between the two side walls of the container and the receptacle, and into the reset reservoir upon any manner of inversion of the timer. Partial definition of the receptacle by such indentations makes the timer manufacturable in two-part molds. Baffles between the reservoir and the body of the timer define an aperture positioned above and many times smaller than the loading orifice of the receptacle and direct and flowable medium into the receptacle when the timer is returned from an inverted to an upright position.

The timing device is formed from a transparent plastics material and it comprises a first chamber (18), a second chamber (19) and a narrow neck (20) interconnecting the two chambers. A particular material (21) is located within the device and it is flowable, under the influence of gravity, to pass from the first to the second chamber and vice versa by way of the neck (20). A passageway (24) interconnects the first and second chambers (18 and 19) and provides an unimpeded passage through which the material (21) can be directed, by appropriately orientating the device, as an alternative to trickling it through the neck (20).

    Abstract: A dietary control eating utensil is disclosed for indicating when food can be eaten therewith. The handle of the utensil includes a gravity-powered timing device. The device includes an elongated transparent material chamber for containing immiscible fluids having different densities such as air and mineral oil. The lighter density fluid forms a visible signal within the chamber that is moveable between the distal and proximal ends. The period associated with the movement of the visible signal depends on the different elevations of the chamber ends. The shape of the chamber along with the density of the two fluids also contributes to the time period the visible signal takes to move between the two ends of the chamber. When the air bubble moves to a predetermined position within the chamber, this indicates when the utensil may be used for consuming food.

    Abstract: A counting device with ball actuated, aligned, rotatable indicating elements is disclosed that is particularly useful as a clock. The device includes a plurality of indicating elements rotatable around parallel axes, arranged side by side in three columns. Each indicating element includes a display portion and a ball actuated flange, mounted on a common axle with the flanges of adjacent elements in each column forming a ball conveying track. The elements are successively rotated to the upward display position by a ball whose continued presence atop an element's flange causes an appropriate rotation of that element. The balls are continuously recycled by a synchronous motor elevator which collects the balls at their lowest position and returns them to their highest position in communication with the ball conveying tracks. After all of the indicating elements in a column have been raised to their display position, the ball resets the first rotated element causing it to reset the adjacent elements.

  • Patent number: 4332096
    Abstract: A gravity flow display device which is usable for selectively and alternatingly exhibiting two different but conceptually related displays. The device has two thin transparent walled half-hourglass compartments through which displays at their rears are visible. The device further contains non-transparent particulate matter which is capable of flowing from compartment to compartment in response to gravitational force and which is of a sufficient quantity to almost completely fill only whichever of said compartments contains it. When said non-transparent particulate matter is contained within one of the two transparent compartments, the display attached to said compartment is blocked from view.

  • Patent number: 4228649
    Abstract: A timing device comprises a container of a transparent material, a channel in said container, and a flotation liquid and a float in said channel, said float having a density different from that of said flotation liquid. Flotation liquid compositions are disclosed which provide a transit time of said float through said channel which is essentially independent of temperature over the normal ambient room temperature range. A number of the embodiments provide for adjustment of the transit times over a substantial range of times.
