Abstract: A method of manufacturing laminated plates, pencil boards or shafts for utensils for writing, drawing or painting, wherein the method includes initially producing in a container a pulp essentially composed of raw material powder and/or fibers and water, wherein the pulp is essentially free of binding agent, applying the pulp onto a screen and predrying the pulp in layers in the form of webs or foils so as to form a non-woven fabric, rolling the fabric onto a roller, applying between the material layers a connecting layer of binding agent, adhesives and/or other additives and cutting, dehydrating and drying the resulting plates and subjecting the plates to further processing.

Abstract: A compass with an adjusting mechanism for adjusting the compass legs and for changing the distance between the compass points, wherein each compass leg includes a pivot bearing and an adjustment bearing. Each compass leg is constructed as a two-armed lever, wherein a first lever arm of each lever extends along the compass leg axis from the pivot bearing to the compass leg point, on the one hand, and a second lever arm extends from the pivot bearing to the compass arm end. The adjustment bearing, or a tilting bearing constructed as the adjustment bearing, is arranged in the second lever arm of each two-armed lever forming a compass leg.

Abstract: An aqueous ink having an extended cap-off time and a process for manufacturing the ink, wherein the aqueous ink is composed of water as the predominant or exclusive solvent, hydrocolloid/hydrocolloids or polysaccharide/polysaccharides as binding agents or film-forming agents, moist-keeping agents, coloring agents, emulsifying agents and possibly additional additives, wherein the ink further includes gum arabic and bees wax as film-forming agents. The ink is particularly an ink for writing, drawing, painting, printing or marking on normal paper or other absorbent writing carriers. The ink is particularly intended for use in fountain pens, ballpoint pens or stencil writers, in so-called felt-tip pens or pencils, in ink jet systems and/or in other capillary duct writing devices or systems.

Abstract: The present invention relates to an ink or India ink for variable ink applications, for writing, drawing, painting and printing, especially in connection with ink-jet systems or other mechanical writing, printing, painting or marking methods and/or devices, made up of organic solvent, as well as of a coloring agent and, optionally, water, binding agent and/or further additives. The coloring agent includes at least two chromophoric components, of which, in the print image, or after the stroke application or color application, at least one coloring-agent component is water-soluble, and a further coloring-agent component is water-insoluble. The components should include various colorants and/or color pigments, and should have at least one colorant that is water-soluble in the stroke application--especially under the influence of heat--and one water-insoluble colorant and/or one water-insoluble color pigment.

Abstract: An ink set (TS) containing of a plurality of inks (T1, T2, T3, T4, T . . . ) of various ink colors, containing at least one red or magenta-colored ink, one blue or cyan-colored ink and one yellow ink plus optionally also a black ink, in particular for use in ink jet printers, where each ink (T1, T . . . ) contains at least one soluble dyestuff (FS1, FS . . . ) as the essential coloring agent (FM) and water (W) and/or organic solvent as the main solvent (LM) and one or more drying retardants (TV) and optionally preservative(s) (KM) and/or other additives (Z1, Z2, Z3, Z4, Z . . . ).

Abstract: An aqueous writing agent, drawing agent or painting agent as an application material is composed of water, binding agent, coloring agent, surface-active agent and possibly other additives, such as particularly preservatives, thickening agent, filler and/or other addition agents, wherein the binding agent is or contains a wax or a wax mixture in an emulsified or dispersed state. The application material is present as a liquid or pasty material and can be used in or with various application devices or can also be used for finger painting. Specifically, the agent contains 40% to 80% by weight water, 10%-50% wax or wax mixture, 0.1% to 2% by weight surface-active agent or emulsifying agent, 01% to 10% by weight coloring agent, and 0.01% to 20% by weight other additives.

Abstract: A writing or drafting instrument includes a writing medium container in the form of an exchangeable cartridge and a push member which is axially movable in the shaft of the instrument and is used as an ejector. The cartridge is held in the shaft by a clamping action or a positive locking action. The push member and shaft form a structural group in which the push member and the shaft are movable relative to each other. The push member acts on the cartridge at least during the ejection of the cartridge. The writing tip is exchangeably fastened in the cartridge or in the shaft.

Abstract: The invention concerns a rubber eraser made of a binder and plasticizer, as well as fillers, pigments and/or other additives, if applicable, which contains polyalkyl methacrylate (PAMA), especially polymethyl methacrylate (PMMA), polyethyl methacrylate (PEMA), polypropyl methacrylate (PPMA), polybutyl methacrylate (PBMA) and/or copolymerizates of these as the binder. Furthermore, the invention concerns processes for manufacturing such rubber erasers, where either first, a plastisol of fine-grain polyalkyl methacrylate and plasticizer is formed, and fillers, internal lubricants, pigments and/or other additives are then mixed into this plastisol, or according to which first, the PAMA powder, the filler as well as any other dry components such as internal lubricants, pigments, etc. are intimately mixed while dry, and the liquid plasticizer is then added to this mixture and mixed or kneaded in.

Abstract: A water based pigmented ink for writing, drawing, painting, printing or marking, is composed of coloring matter, additives, and water as solvent. The coloring matter is a pigment formed of one or more alkaline dyes and of a solid polymer dispersion component. The ink contains an acid group-free polyhydroxy compound as a stabilizer, and at least one surfactant and/or emulsifier, as well as a preservative.

Abstract: Protective cap for capillary writing instruments comprised of a relatively flexible outer casing and a relatively rigid inner casing. One end of the outer casing is adapted to form a substantially fluid tight seal on the body of a writing instrument. A flexible sealing means, e.g., spherical, is positioned between the inner sheath and the outer sheath so as to form a substantially fluid tight seal on the tip of a writing instrument inserted into the inner casing and placed in contact with the sealing means. In another embodiment the sealing means located between the outer casing and inner casing is eliminated and the outer casing forms a substantially fluid tight seal by directly contacting the writing instrument tip.

Abstract: A method and composition are disclosed for the preparation of pencil lead from clay, graphite and optionally other material, wherein the clay or the clay/graphite mixture is digested with water, pressed, dried and fired, and at least one alkali phosphate, alkali borate and/or alkali carbonate is added before or as part of the digestion of the clay or the clay/graphite mixture.

Abstract: A writing tip for ball point pens include a receiving bore for a writing ball worked into the tip housing, a circumferential support surface inclined towards a central feed bore and arranged between same and with receiving bore, feed channels discharging into the central feed bore and into the support surface and spherically-shaped support zones adapted to the ball. Capillarity increasing intermediate surfaces respectively between the spherically-shaped support zones and the feed channels.
