Abstract: This invention provides an image-forming and image-transferring sheet comprising a base layer having a first surface and a second surface. The base layer is impregnated with a first image-forming reactant whereas each of the surfaces of the base layer has coated thereon a microporous membrane layer having a gradient in elasticity across the thickness thereof. The more elastic surface of the membrane is in contact with the base layer. The other surface of the membrane is coated with a second image-forming reactant. Upon impact by an image instrument such as a typewriter key, the membrane becomes extended to allow diffusion of the first reactant through the membrane to react with the second image-forming reactant on the surface of an adjacent sheet to form an image on the surface of the adjacent sheet. A method of preparing an image-forming and image-transferring sheet is also provided.

Abstract: A plurality of fingerprints of a person are recorded by applying a solution of a first substantially colorless chemical reagent to the fingertips. Essentially invisible fingerprints are obtained by gently pressing the fingers having the solution of the first chemical reagent thereon on a suitable recording sheet. Subsequently the recording sheet is exposed to sublimed vapors of a second chemical reagent. The first and second chemical reagents are selected to react with one another to yield a highly colored substance which is formed on the surface of the recording sheet providing a visible image of the fingerprints. Ferric chloride and a 8-hydroxyquinoline are ideally suited chemical reagents for use in this invention. An apparatus of unitary construction incorporating a replaceable dispensing pad having the solution of the first chemical, is disclosed.

Abstract: A portable thread dyeing kit comprises, preferably, a plurality of separate compartments each containing a liquid dye with an integral felt piece inside the compartment, the felt piece reaching into the dye and being soaked with same. Near the top of each compartment is a pair of orifices in opposite side walls of the compartment for transversely passing a needle through the container and through the respective felt piece. Accordingly, as a white thread is passed through the appropriate felt piece, the thread is dyed to the respective color. The device is extremely simple and thus inexpensive to produce as it avoids split arrangement of absorbent pads used for the same purpose in prior art.

Abstract: A low cost line printer character chain lubricating device that provides an accurate amount of lubricant between a line printer character chain and the hard, smooth support surface about which the chain rotates. The lubricating device is located in a depression in the hard, smooth support surface and includes a piece of flexible, abrasion-resistant, microporous nitrile rubber that is impregnated with lubricating oil. The nitrile rubber has a smooth convex arcuate surface for contacting the character chain. A bracket semipermanently mounts the nitrile rubber in the depression in the support surface such that the convex arcuate surface of the nitrile rubber contacts the side of the character chain that normally contacts the hard, smooth support surface as the chain rotates. Depressions in the nitrile rubber beside the arcuate surface serve as charging reservoirs for the lubricating oil.

Abstract: An inking device and a method of inking business machines are disclosed in which the inking device has a spool-like body with a central ink reservoir, and an ink conducting washer-like pad of cellular plastic material is in communication with the ink reservoir to receive ink from the reservoir near its inner periphery and to conduct it by capillary action to its exposed outer periphery situated beneath a tubular inking pad mounted on the hub of the spool-like body. The bottom of the inking pad is in contact with the exposed periphery of the ink conducting pad near the outer surface of the inking pad to pick up ink therefrom and to transmit ink upwardly of the inking pad by capillary action. Ink is delivered from the inking pad to a ribbon, or to a type slug, which contacts the inking pad to pick up ink therefrom as the ribbon or type slug moves past the inking pad.

Thereafter the next label in said stack is automatically advanced to said ready position and remains in this position until it also is manually removed. The use of such a label dispensing and moistening arrangement greatly facilitates the manual grasping of successive moistened labels and the application thereof to items that are to labeled.

Abstract: A water applicator includes a closed water main reservoir connected to a holding member for supporting the core of a tape roll. An auxiliary water reservoir is disposed in an upper portion of the main water reservoir with a water absorbing member positioned in the auxiliary water reservoir to contact the tape as it is withdrawn from the holding member. A scraper is disposed on the holding member in front of the absorbing member to remove excess water from the tape to prevent the tape from dripping. The applicator is convenient to carry and free of dripping even when turned upside down.

Abstract: A hi-fi stamp pad comprising a pad vessel, a substrate whereupon a kind of fiber is vertically planted and thus a flock surface formed thereon, a bolster which is buried under the substrate and contained in the pad vessel whereby to hold ink for stamp use, and a ringlet compulsively rounded the inner brink of the pad vessel to set steadily the substrate upon the bolster. Being first filtered through the substrate, the ink is absorbed upward from the bolster by the flock and accordingly, appropriately wets the flock surface thereof. Once a stamp or seal touches the flock surface, the latter brushes the ink evenly upon the engraved character surface and breaks the ink surface tension built thereupon whereby to regulate the ink adhesion and to make the stamped characters very clear.

Abstract: A method and device for applying ink to a ribbon, such as a typewriter ribbon or the like. The device is characterized by a pair of ink-absorbent pads resiliently supported in a mutually opposed relationship for transferring ink to a ribbon as the ribbon is drawn between the pads in face-to-face engagement therewith.

Abstract: A tape dispenser for applying electrially conductive adhesive tape or foil on a flat surface. When applied on a flat surface, the tape forms a part of an electrical alarm system. The dispenser includes a housing having a tape storage chamber in which is rotatably mounted a roll of tape. The housing has an extension on the front side thereof through which the tape is dispensed. A pressure member is mounted on the housing extension over the point at which the tape is discharged from the housing extension for use in pressing the tape on a flat surface as it is discharged from the dispenser. The housing is provided with a guide means for guiding the dispenser in a straight line. The guide means is used for engagement with a window frame for guiding the dispenser as it moves over the window pane. The tape dispenser can also be used for making a right angle turn when applying tape to a flat surface.

Abstract: A gummed tape dispenser has a pair of V-shaped cutting blades for making successive V-shaped cuts in the ends of a length of tape drawn from the dispenser to provide arrow-shaped lengths of tape. The tape dispenser has a tape moistener whose central portion is masked to keep the central portion of the tape dry as it is drawn across the moistener so that the central portion of the tape will not stick to a surface (e.g. the flaps of a box) to which the moistened tape is glued. Thus the unglued tip of the pointed end of the tape can be subsequently grasped and the tape can be stripped away to facilitate opening of the box.

Abstract: An apparatus for forming an electrically insulating semi-cured or cured in situ polymer containing material over a surface of an electrode can of an electrical device. The apparatus includes an applicator forming a film of curable polymer containing material over the can and means semi-curing or curing in situ the film to form an electrically insulating semi-cured or cured polymer containing material over the surface of the electrode can. The film is formed by contacting a surface of the electrode can with curable polymer containing material dispensed from the applicator and moving the surface of the electrode can contacted with the material over the applicator to distribute the curable polymer containing material over the surface of the electrode can as a film.
