  • Patent number: 4932941
    Abstract: There is disclosed a disposable and non-reusable syringe which has its piston locked in its forward dispense position after it is used, and the plunger is pulled out from the piston if the plunger is sought to be retracted from the syringe. The non-reusable syringe is so constructed to prevent the piston from reengaging with the plunger, even if the plunger is retracted and sought to be reinserted.

  • Patent number: 4911186
    Abstract: A convertible hair roller includes first and second flexible outer sheets connected together in parallel spaced relation, two parallel memory wires positioned between the sheets and capable of repeated deformation between a straight configuration and a circular configuration, with each memory wire automatically deforming from the straight configuration to the circular configuration upon application of heat of a predetermined temperature thereto so that the first and second sheets also automatically deform into a cylindrical configuration; and heat sink wires positioned transversely with respect to the memory wires between the first and second sheets for retaining heat applied to the hair roller. When heat is removed from the formed memory wires, they retain their circular configuration, but can be manually biased back to their flat configurations.

  • Patent number: 4903840
    Abstract: A method of manufacturing adhesively-securable, fingernail coatings and an adhesively-securable fingernail covering product, too. The nail polish-like material is provided in semi-solid form on a sheet of adhesive-backed peel-off paper, which, when removed, exposes the adhesive of the fingernail coatings. The fingernail coatings are, after removal from a substantially air-tight package, cut into individual sections, located on the fingernails and pressed onto the fingernails to secure them there, temporarily, i.e., until they are desirably removed. The edges can then be cut to the length and width, as well as the curvature of the nail on which they are placed. The semi-solid nail enamel product is originally sealed in an air tight envelope to ensure that the coatings do not fully dry out during shipping and storage.

  • Patent number: 4893816
    Abstract: Dice game methods involving three dice and a doubling cube. The methods involve the providing of an objective total count to be reached to win the game, assigning a value to each face of the dice, permitting a first player to continue rolling as long as a certain minimum value is achieved for each roll, establishing an initial entry level beyond which the player can retain an accumulated count, permitting a player to stop rolling to fix his cumulative count and recommence accumulating a count during his next roll, returning the count to the last stopped cumulative count if the player does not achieve the minimum value on a given roll, and allowing the player whose turn is about to begin to offer the doubling cube to the opponent whereby the stakes are doubled if the opponent accepts the doubling cube or the game is won by the offering player if the opponent refuses to accept the doubling cube.

  • Patent number: 4878484
    Abstract: A water-tight endoscope comprising a flexible tube zone, a handle zone and a guide tube zone is disclosed. Each of the flexible tube zone, the handle zone and the guide tube zone has a water-tight structure, and moreover, a connecting part for each zone has a water-tight structure. An opening for connecting the interior of the endoscope to the outer air is formed in the guide tube zone and a waterproof and breathable filter is arranged in this opening. By this arrangement, the interior of the endoscope is connected to the outer air through the waterproof and breathable filter.

  • Patent number: 4862101
    Abstract: A system for producing spectrally pure optical pumping light at a resonant frequency is disclosed for molecular species and atomic isotopes. A Faraday filter is used as a transmission filter, and the frequency overlap between the output of a light source containing the atomic or molecular material and the spectrum of the Faraday filter allows optically pure pumping light to emanate from the filter. Cross-polarizers are used to further reduce background noise.

  • Patent number: 4777996
    Abstract: A plastic base for use with a cylindrical flask for the elimination of wax patterns prepared for making metal castings by the lost wax process is identified. The base is made of a plastic material which is used in place of conventionally found rubber bases. The base is constructed of a thin-walled resilient plastic material and allows for direct set up of the wax patterns, as well as increased speed in the preparation of the plaster mold in the cylinder for making metal castings. The plastic base comprises an inner annular raised platform comprising a shoulder and the cylindrical flask is pressed on the shoulder deforming the plastic about the bottom edge of the flask to form a seal between the base and flask.
