The poly(meth-)acrylate contains free carboxyl groups and has a degree of esterification of 0.55 to 0.9. The adhesive has a wide range of applications and can be transparent.

Abstract: The present invention relates to a typewriter ribbon made up of a flexible thin support and a transferable mass placed on the flexible thin support. The transferable mass comprises a surface-active dispersing agent and a surface-active resin dissolved in a medium-boiling solvent.This ribbon is useful for correctable typing on delicate or treated paper, e.g., photocopied paper.

Abstract: The device, suitable for use in a hand roller, for transferring a film from a carrier tape to a substrate is a cartridge containing a feed reel and a windup reel. The tape travels by way of a protruding stiff applicator bar which has a pressure-applying edge for pressing the tape against the substrate. The stiff applicator bar is on a spring support member which can be deflected until a protrusion on the bar encounters a detent fixed on the housing. The application bar has its pressure-applying edge appropriately shaped to facilitate the transfer action.

Abstract: An applicator for adhesive film to a surface has a supply spool for tape carrying the film and a take-up member coupled to the supply spool by a drive mechanism. The tape passes around an applicator member which is resiliently mounted on the housing and can press the tape against the substrate so that the adhesive film is transferred to the latter.

Abstract: A hand-operated device for transferring a film from a carrier tape to a substrate has a housing made up of two parts connected by a swivelable linkage. The housing has two rotatable pivot pins coupled to each other by a clutch coupling. A cartridge is held in position in this housing by a suitable arrangement of pins and receptacles. This cartridge has, conrotatably linkable to the pivot pins, a feed reel and a wind-up reel for the tape, and has an applicator element at one end over which the tape runs and which is used to press the tape against the substrate for transfer of the film.

Abstract: A fabric printer ribbon impregnated with a transfer medium comprised of a vehicle liquid and coloring agent dispersed in the vehicle liquid. The fabric printer ribbon may further contain property-improving additives. As the coloring agent, the ribbon contains a color reaction product in the form of a Lewis-acid/Lewis base color complex comprised of an organic chromogen and a color developer. The coloring agent is dissolved and/or dispersed as fine particles in the vehicle liquid. Such a fabric printer ribbon displays the advantage of correctability by means of an inhibitor of the color reaction. The corrected sheet can be typed over in customary fashion by means of the fabric printer ribbon in a second track of a fabric printer ribbon.

Abstract: At least two trays are positioned over each other which are lockable by a cover. One of the trays is a drawer which is lockable in an inserted position with the cover. The paint box can have an upper and a lower tray and the upper tray can comprise a rectangular housing with a foldable cover. The rectangular housing has double side walls extending downwardly and forming a guide for the lower tray which is the drawer. The undersurface of the drawer can form the supporting surface for the housing while the upper tray housing rests on the drawer. The double side walls of the rectangular housing end with a small space above the bottom plane of the drawer and the inserted edge of the drawer can be lowered an amount corresponding to that small space. The pulled out end of the drawer can have a strap which projects upwardly over the upper tray and engages under the edge of the foldable cover.

Abstract: A thermal transfer ribbon consisting of a color-transfer layer on a foil or film substrate band is provided with a wax coating which appears to facilitate transfer with high resolution even to rough papers.

Abstract: A method of and apparatus for the production of wicking tips for pens and markers in which the blanks, pointed at their ends, are first notched on opposite sides and are then cut through between the notches to form two tips from each blank. The invention simplifies the sharpening and dressing required of the tools which are used.

Abstract: A thermocolor ribbon comprises a plastic support foil, a fusible color layer attached to one side of the plastic support foil and an organic coating layer covering the other side of the plastic support foil. The organic coating layer is composed of a nonfibrous, pressure-stable wax or waxlike substance. A process for making the thermocolor ribbon from a plastic support foil having a fusible color layer thereon comprises application of a solution containing an organic coating material to the side of the foil not having the fusible color layer bonded thereto, followed by solvent evaporation. Alternatively, the side of the support foil bearing the fusible color is brought into intimate contact with opposite side of the foil whereupon the latter is heated for a time sufficient for transport of material from the fusible color layer to the uncoated side of the foil to form the organic coating layer thereon.

Abstract: An indicating cap for a writing instrument has an insert with a blind passage adapted to fit over the tip of e.g. a felt or fiber tip pen or marker and axially movable in a sleeve forming a cap between two limiting positions. One of these positions is defined by a spring detent shoulder against which a shoulder of the insert abuts when the cap is withdrawn from the writing implement. When the cap is thrust properly onto the writing implement the insert is pressed into its second position in which a pin of appropriate color is visible through an end of the sleeve where the projecting pin can be protected by a hood or basket.

Abstract: A printing ink for capillary or jet printers adapted to form a mechanically erasable image, comprises a latex-based aqueous polymer dispersion including a water-soluble or organic-solvent soluble dyestuff coloring the particles of the dispersion without the use of additional solvent.

Abstract: A writing instrument having a capability tip is formed by piercing a membrane between the mouth of the housing and the reservoir with a tool to provide an opening of the size and shape of the shank of the nib which is then introduced into the opening.

Abstract: A multiple overstrike carbon ribbon utilizes a low-viscosity oil base in the form of mineral oil with 25 to 50% of aromatics and nevertheless does not permit the transferred color to bleed on the substrate. The ribbon is particularly useful for daisy wheel and like high-velocity printers.

Abstract: A writing wick for felt markers and pens is formed by an elongate bundle of individual monofilament thermoplastic strands. Longitudinal channels are defined between the strands. The strands are selectively merged parallel to the direction of the longitudinal axis of the bundle sealing and isolating the longitudinal channels from each other and outwardly enclosing the channels. The longitudinal channels defined by selectively merged strands are operatively interconnected by radial capillary ring grooves (14) or by axially extending capillary incisions 15 penetrating from the outside of the bundle inwardly in the vicinity of the writing tip of the wick. Several longitudinal channel and interconnecting capillary ring grooves (14) or capillary incisions (15) may be used.

Abstract: A multiuse carbon transfer material, e.g. a carbon "paper" or carbon ribbon has a synthetic resin support film or foil having a coating which contains, in addition to a synthetic resin binder, a coloring agent of an oil base type. The oil forming the base for this coloring agent is a polyoxyethylene tenside which forms a plasticizer for the synthetic resin material of the binder.

Abstract: A portable, electronic, desk-top information display device for office use in recording and selectively displaying information, comprising a keyboard the keys of which are operable to control the operation of electronic circuitry forming part of the device, and a stationary display panel on which the said electronic circuitry is adapted to produce a matrix array of illuminated dots of other discrete display items in a multiplicity of substantially equi-distant columns, with each dot being illuminated independently of all the others, so as to permit a plurality of letters, numbers or other symbols to be displayed simultaneously across the panel with the majority of such symbols having a width of at least two columns.
