Abstract: An apparatus for adjustably retaining an expendable medium for writing or drawing such as for a crayon core, a wax or oil based pencil (colored pencil) core, a chalk core or a pastel core includes a tubular barrel, at least one elongated arcuate body element, and a follower in abutting engagement with a portion of the body. The follower has a helical surface feature corresponding with spaced surface features of the body. The follower is configured to receive a non-writing end of an expendable core. The apparatus is configured such that the outer barrel of the apparatus can be made from a paper based material such as paperboard or other fibrous material that is more eco-friendly than other material such as plastics.

Abstract: A vented output device for uniformly mixed liquid comprising a barrel defining a reservoir for containing the uniformly mixed liquid, and at least one vent channel extending from a first vent opening in fluid flow communication with an exterior of the device and second vent opening in fluid flow communication with the reservoir. A binary ink storage assembly includes multiple glass ampoules arranged in pairs, which are placed inside the barrel in parallel. The invention provides a reliable, simple and low-cost output device for solving the problem of not allowing the liquid to be uniformly mixed and output when a chemiluminescent marker or pen is activated.

Abstract: An adjustable device projection system includes a main housing, a base, and a device holder. The main housing has a lens defining a focal axis. The base is coupled to and extends from the main housing. The device holder is coupled to the base and is configured to hold a mobile device generally in optical alignment with the at least one lens. The system may include an adjuster to adjust the mobile device relative to the lens or adjust an orientation of the focal axis. The adjuster may include a track along which the device holder adjustably slides. The adjuster may include a support configured to adjust an orientation of the focal axis. A kit including the adjustable device projection system and a light board system configured to display images projected via the projection system.

Abstract: Disclosed herein are a water and wax-based ink, a marking instrument comprising the water and wax-based ink, and a kit comprising the marking instrument and a marking element comprising a non-porous surface, wherein a mark applied on the non-porous surface using the marking instrument is substantially removable without application of any solvent. The water and wax-based ink composition comprises an opacifying waxy material, a dispersant, water, and optionally a dye.

Abstract: A marking system includes a composition having at least one color precursor, a moldable substrate having a color developer, and a marking instrument for applying the composition to the moldable substrate to form at least one mark on the moldable substrate. A method of producing a colored three-dimensional molded object includes the steps of manipulating a moldable substrate having a color developer into a molded shape having an outer surface; and applying, on the outer surface of the molded shape, a first composition having at least one color precursor to a first portion of the molded shape.

Abstract: A non- or low-boron putty base includes a crosslinked reaction product of at least one polydiorganosiloxane that has at least two reactive functional groups and at least one crosslinker capable of reacting with the reactive functional groups to form the crosslinked reaction product. The putty base is dilatant and may include 0 to 0.1 weight percent of a boron-containing compound. Dilatant putties made from the putty base and fillers are also provided. A method of making a dilatant putty includes: providing at least one polydiorganosiloxane including at least two reactive functional groups; providing an additive; providing at least one crosslinker capable of reacting with the reactive functional groups; and combining the polydiorganosiloxane, the filler, and the crosslinker to form the dilatant putty having less than 0.1 wt % boron.

Abstract: The present invention provides writing compositions that are capable of being erased or changed in color chemically. The present invention also provides erasing media for erasing or changing the color of marks produced with the writing compositions, as well as writing systems and incorporating the erasing media and the writing compositions. The present invention further provides writing instruments produced using the writing compositions.

Abstract: A thermoplastic writing composition includes at least one particulate filler including one or more of days, silicates, or carbonates, at least one thermoplastic binder material including one or more of high density polyethylene, polypropylene, and styrene, one or more waxes chosen from soy wax, paraffin wax, and beeswax, at least one colorant, and optionally, at least one surfactant.

Abstract: The marking system includes one or more ink compositions and a color-change agent composition. The ink composition applied to a substrate such that it is a first color, but when a color-change agent is applied, one or more secondary colors appear. The ink compositions each have a respective ink color and include a respective: at least one first dye composition having a respective first color and at least one second dye composition having a respective second color. The first dye composition can react with the color-change agent composition. When the color-change agent composition contacts the ink composition, each respective first dye composition reacts with the color-change agent composition, 10 thereby producing each respective second color. Each respective first color is different from each respective second color, and each respective second color is different from each respective ink color.
