Patent number: 5338129Abstract: A method and apparatus for applying colored foam markers to road surfaces as a means of temporarily changing or outlining traffic patterns. In the preferred embodiment, dissoluble foam markers would be periodically deposited upon the road behind a work crew to alert motorists of a potential hazard ahead, in order to avoid any collisions between the motorist and the work crew. As the work crew would move up on the road, the foam markers would naturally dissipate and substantially disappear over a predetermined or a relatively short period of time so that the roadway automatically returned to its original traffic pattern when the work crew has left the area. Foam markers according to the present invention would enhance the safety of a work crew's operations and increase work output by freeing the work crew from the obligation of retrieving the markers after they are used.Type: GrantFiled: October 13, 1992Date of Patent: August 16, 1994Inventor: Alan D.

Patent number: 5289846Abstract: An automatic water replenishing system is designed for use with multiple dye vats used for tinting eyeglass lenses, but the broad principles of the invention could apply to other systems used for replenishing individual ones of plural vats or reservoirs with water or some other liquid. A rotary water distributor rotates about an arc when it is signaled by water level sensors that the water in a particular vat is low. As the rotary distributor reaches the low reservoir, the LED carried by the distributor actuates a photo transistor adjacent the particular reservoir that needs replenishing, causing the motor to stop and the water supply solenoid valve to be actuated, filling the reservoir until a brief period of time after the level sensor indicates a full condition to the central control system.Type: GrantFiled: December 26, 1991Date of Patent: March 1, 1994Inventors: Tariq J.

The slide houses a plurality of optic fibers with one end of each fiber terminating at a light-receiving panel and the other end of each fiber terminating at a digital read-out panel. The ends of the fibers at the digital read-out panel are arranged to form, e.g., a generic "88" configuration, from which the digits 0-99 may be formed. In operation, the band is pulled through the opening in the slide and light passes through the transparent areas of the band and into the light receiving panel. The light continues through the optic fibers and lights up a particular digital configuration at the digital read-out panel. The slide and band may be useful e.g., as a belt-like device for measuring one's waist, or as a carpenter's tape measure.Type: GrantFiled: June 16, 1983Date of Patent: November 20, 1984Assignee: Toybox CorporationInventors: Hajime Matsumoto, Kouji Okada, Nobuo Sano

Patent number: 4479996Abstract: The film disclosed in the application is secure against forgeries and serves for marking articles, in particular high-quality branded goods. It is comprised of at least one transparent polyester film oriented by stretching and containing in its composition an organic dyestuff which is heat stable at temperatures above about 260.degree. C. Preferably, a laminate is used which is comprised of two films, one of which contains a different colored dyestuff than does the other.Type: GrantFiled: July 28, 1981Date of Patent: October 30, 1984Assignee: Hoechst AktiengesellschaftInventors: Helmut Sch/a/ fer, Manfred Unger

Patent number: 4475476Abstract: A signal device for indicating, by day or by night, the location of a person adrift on the surface of a body of water, consisting of a vividly colored inflatable tube made of thin, flexible but nearly inextensible material, provided with a one-way valve for inflation by mouth, and a miniature electric lamp coupled to a water-activated battery. The tube is permanently attached to a life jacket or other garment and has a flag secured to its free end. The tube or the flag or both contain a metallic pigment or are covered with a layer of such material so as to be radar detectable.Type: GrantFiled: August 10, 1981Date of Patent: October 9, 1984Inventor: Thomas L.

Patent number: 4466588Abstract: This travel direction indicator is for model railroads, and serves to indicate the direction a model train will travel on a track. Primarily, it consists of a pair of spaced-apart optical fiber rods, each having arrow head like indentations, the group on one rod facing in one direction and the other group, of the other rod, facing in the opposite direction. It further includes a panel for mounting the rods, and a switch is coupled to a pair of bulbs in the panel to illuminate each rod selectively, which will indicate the direction a train will travel, by the lighting up of the arrow-like indentations.Type: GrantFiled: June 21, 1982Date of Patent: August 21, 1984Assignee: J.

Patent number: 4445163Abstract: A boat light is especially adapted to be mounted upon the transom or stern of a cabin cruiser, speedboat, small yacht, or the like. A holder for a lamp unit has a spherically curved outer surface engaging a complementary inner surface of a housing attachable to the hull of the boat. The holder is universally adjustable to selected angular positions of adjustment relative to the housing. In a typical adjustment, the beam of the lamp unit may be projected horizontally despite the inclination of the transom from the vertical. In the selected position of adjustment, the tightening of screws by which the device is assembled and mounted on the transom is effective to preserve the lamp unit holder adjustment. This occurs when a shield closing the inner end of the housing is caused to bear against a rearwardly projecting surface of the holder. The holder, or at least the shield-engaging surface thereof, is of a deformable material.Type: GrantFiled: April 26, 1982Date of Patent: April 24, 1984Inventor: Theodore Ziaylek, Jr.

Patent number: 4439346Abstract: Polydiacetylene gel compositions, comprised of a polydiacetylene and a gel-forming liquid therefor, are described which undergo a change in color and in physical state to a solution when heated to a predetermined temperature. The gel compositions exhibit hysteresis temperature characteristics which allow the original color change to be maintained and recorded until the solution is cooled below the predetermined temperature. Thus, the gel compositions are useful in temperature-indicating devices for reversibly monitoring a wide range of temperatures. A novel class of polydiacetylene compounds is also described, useful in forming the gel compositions, formed from monomeric diacetylenediol bis(alkoxycarbonylmethylurethanes).Type: GrantFiled: August 30, 1978Date of Patent: March 27, 1984Assignee: Allied CorporationInventors: Gordhanbhai N. Patel, Dawn M. Ivory

Patent number: 4422402Abstract: An apparatus for detecting the remaining amount of rolled paper, the diameter of which decreases as it is unrolled, comprises a detection lever which is swingable in a manner such that its free end is always in contact with the decreasing outer diameter of the roller paper. The detection lever includes a magnet piece which actuates a magnetism sensor for actuating an alarm device indicating the time for exchanging the roller paper when the diameter of the paper roll decreases to a predetermined diameter.Type: GrantFiled: February 20, 1981Date of Patent: December 27, 1983Assignee: Ricoh Company, Ltd.Inventor: Masato Ogihara

Patent number: 4419070Abstract: A method of producing a decorative movement of metal particle display in a pool of molten wax of a burning candle. Portions of a wax crayon containing colored metallic particles different from the color of the candle wax is melted in the flame of the candle and directed to fall into the molten pool for observation.Type: GrantFiled: April 2, 1981Date of Patent: December 6, 1983Assignee: Chicago Digital IncorporatedInventor: Alexander Z.
