Abstract: A stuffed, sealed envelope assembly has superimposed front and back plies with insert material within the envelope unattached to the plies so as to be freely disposed therein. At least one cut line or a line of perforations defining a removable portion is provided in one of the envelope plies in the vicinity of an edge of the insert to facilitate opening of the envelope for exposing the insert for extraction. Chip elements, provided for immobilizing the insert within the envelope, underlie the removable portion and are secured thereto so as to be moved away from the insert upon removal (wholly or partially) of the removable portion. An outline of a simulated flap is applied to the outer surface of the one envelope ply so as to overlie or be delimited by the cut line or line or perforations. Other fold lines may be applied to the same outer surface so as to give the impression together with the flap outline of a folded-flap envelope construction.

Abstract: Disclosed are improved microcapsules comprising a core of fill material, at least one generally continuous wall encapsulating the core, and the reaction product of a methylolated epoxy compound and material of the outermost wall as at least a portion of the outermost surface of the microcapsule, the reaction product, among other things, tending to close discontinuities in the encapsulating wall. When containing a colorless dye precursor and utilized in carbonless copying systems, the improved microcapsules help to reduce discoloration caused by leakage or premature rupture and release of the dye precursor while still providing good image intensity of marks produced by the system. Also disclosed are methods of making the improved microcapsules.

Abstract: An improved two part mailing wrapper for magazines and the like is disclosed and includes a first, outer sheet adapted to be wrapped about the magazine during mailing and to have the name and address of the subscriber printed on its outer face. The improved mailing wrapper also includes a second, inner sheet which may be utilized to transmit subscriber personalized information, such as a subscription renewal order notice and a business reply envelope, to the subscriber of the magazine. The inner and outer sheets are constructed and arranged so that both the two part mailing wrapper and the magazine may be mailed at second class publication postal rates.

Abstract: A set of manifold business forms includes at least three plies having selected mating surfaces thereof coated with chemicals which are capable of reacting with one another to produce a colored mark. An intermediate ply of the set is of tissue material having its back surface coated with a color precursor in the form of a microencapsulated liquid, and the bottom ply of the set is of an opaque material having its front surface coated with a composition of a generally solid record-developing material. The top ply of the set is likewise of an opaque material so that, upon the application of pressure to the set, an image thereof is developed on the top surface of the bottom ply. The use of a coated-back tissue avoids capsular damage during the printing operation of the forms since all that is printed is a coated front sheet.

Abstract: A stuffed, sealed envelope assembly has superimposed front and back plies with insert material within the envelope removably attached thereto along at least one marginal edge of the insert. At least one cut line or a line of perforations is provided in only one of the envelope plies in the vicinity of another marginal edge of the insert to facilitate opening of the envelope for exposing the insert for extraction. An outline of a simulated flap is applied to the outer surface of the one envelope ply so as to overlie or be delimited by the cut line or the line of perforations. Other seam lines may be applied to the same outer surface so as to give the impression, together with the flap outline, of a folded-flap envelope construction which is capable of being opened for exposing the insert in a manner similar to that of a folded envelope.

Abstract: An improved business forms stationery assembly including plurality of continuous record webs that are disposed one on top of the other and that may be folded in zig-zag fashion, into a pack of alternate fold lengths. The record webs are joined together by a plurality of paper staple tongues that are oppositely directed in alternate fold lengths of the stationery assembly.

Abstract: A continuous stationery assembly particularly intended for use with typewriters, terminal printers, mini-computers and so on, whether or not such devices embody pin feed driving mechanisms, wherein the assemblies are fed through the machine and refolded effectively, comprising a front and a back outer record web, both with marginal feed apertures, at least one intermediate web with transfer material associated with it, respectively secured to the web next above it, and wherein the two outer webs extend beyond the longitudinal side edges of the intermediate web to form side margins at opposite sides of the assembly, securing means within the respective margins joining the front and back webs together and a further securing means joining the intermediate web to at least one of the outer record webs, longitudinal lines of perforations in the front and back webs adjacent the side edges of the intermediate record web to facilitate removal of the margins and longitudinal lines of perforations in each of said webs t

Abstract: Continuous superimposed webs are interlocked together along opposite marginal edges by sets of superimposed tongues provided in the webs which interengage to effect an interlock. Each set includes at least a pair of superimposed tongues disposed along a line forming an angle with an adjacent marginal edge so that one of the tongues is staggered relative to the other in the direction of feed of the webs through a web processing machine. Thus, during separation of the plies in the direction of feed the forwardmost superimposed tongues are separated before the rearwardmost tongues thereby avoiding simultaneous separation of the tongues and decreasing the resistance offered by the tongues upon ply separation.

Abstract: An improved letter sheet continuous stationery assembly is disclosed, and includes a front web and a backing web. Longitudinal and transverse cuts are made in the front web, but not the backing web, so as to define a plurality of letter sheets. The front and backing webs are permanently secured together along their side margins by lines of adhesive. The letter sheets produced in the front web are temporarily secured to the backing web by other lines of adhesive during the time the assembly is fed through additional forms handling equipment such as a computer controlled printer.

Abstract: Disclosed are normally substantially colorless chromogenic 9-dialkylamino-spiro[6H-[1]benzopyrano[3,2-g]quinoline-6,1'(3'H)-isobenzof uran]-3'-one color precursor compounds having the following structural formula: ##STR1## wherein each R.sub.1 represents a lower alkyl group having from one to five carbon atoms and wherein each of R.sub.2 and R.sub.3 represents either a methyl group or a group which includes a methylene bridge resonance path having up to four carbon atoms, but wherein when R.sub.3 is a methylene bridge resonance path-containing group, R.sub.2 is not a methyl group. These compounds are initially substantially colorless but are capable of becoming highly colored when brought into reactive contact with many Lewis acid materials and the like. Accordingly, these compounds are highly useful as a component of pressure-sensitive copying papers.

Abstract: A series-connected business form is adapted to be fed through the printing means of a business machine and includes a continuous pair of superimposed outer webs each having a row of spaced superimposed feed holes extending along at least one marginal edge thereof for engagement with the feed means of the business machine so that the form may be thereby advanced into and past the printing means. At least one intermediate web is disposed between the outer webs with transfer material lying on opposite sides of such intermediate web, and the intermediate web is secured to only one of the outer webs.

Abstract: A stuffed, sealed envelope assembly has superimposed front and back plies with insert material within the envelope unattached to the plies so as to be freely disposed therein. At least one cut line or a line of perforations is provided in one of the envelope plies in the vicinity of an edge of the insert to facilitate opening of the envelope for exposing the insert for extraction. An outline of a simulated flap is applied to the outer surface of the one envelope ply so as to overlie or be delimited by the cut line or line of perforations. Other seam lines may be applied to the same outer surface so as to give the impression, together with the flap outline, of a folded-flap envelope construction. The envelope assembly is therefore capable of being opened for exposing the insert in a manner similar to that of a folded-flap construction.

Abstract: Information is recorded on the surface of a recording member by signal-controlled non-impact printing means, such as a jet printer or meniscus printer. The recorded information is not necessarily visible, and comprises deposits formed by ion or electron or molecular donor material. The thus-recorded information is detected by pressure contacting the surface of the recording member with a dielectric surface to form a latent image thereon. The latent image may be read or detected as a voltage analog or it may be rendered visible by the attraction thereto of electroscopic marking particles. The deposit formed by such marking particles can be transferred onto a copy sheet or the like.

Abstract: Disclosed is a process for preparing improved microcapsules which are useful in connection with carbonless copying systems. Also disclosed are the microcapsules themselves which comprise minute discrete droplets of liquid fill material including an initially colorless chemically reactive color forming dye precursor and a carrier therefor encapsulated within individual, rupturable, generally continuous polyamide shells formed thereabout. The process comprises the step of incorporating in the fill material, an amount of an epoxy resin or a polystyrene resin effective to render the microcapsules resistent to inadvertent release and transfer of the fill material.

Abstract: A stubless unit set of multiple plies of the type including at least superimposed top, intermediate and bottom plies is made by removably interconnecting the top and bottom plies together and by removably interconnecting the intermediate and bottom plies together. The top and bottom plies are interconnected by providing a fold flap along an edge of the top ply, applying detachable adhesive to the flap, folding the flap to underlie the bottom ply and contacting the bottom ply with the adhesive, and the intermediate and bottom plies are interconnected by providing at least one hole in the bottom ply and extending a portion of the adhesive through the hole so as to contact the intermediate ply. Each of the plies is devoid of any tear lines which may form a stub.

Abstract: A tri-level output sensor senses faulty window construction in a web of continuous business forms of stationery, for controlling visual and audible indicators, including a display of the relative position of the faulty sensed window construction, within a continually fanfolding end stack. Pulsing circuitry drives tri-level-to-digital processing circuitry, conjointly providing referencing information to process the sensor output and timing information to sample the processing circuitry, and drives a pair of counters for fanfold position indication and consecutive-fault-occurrence determination, dependent on the processing output.

Abstract: A forms decollator for separating superimposed continuous forms into separate plies has a pair of abrasive rolls rotatable in opposite directions away from one another and a separator roll bearing thereagainst and wholly supported thereby so that, together with the abrasive rolls, the forms may be separated as they are moved between the abrasive rolls and through the nips of the separator roll and each abrasive roll so as to be directed over guide elements and refolded over pack breakers which permit the separated plies to be neatly refolded. The guide elements have undercut portions near their terminal ends to avoid interference with the separated plies during the process of refolding.

Abstract: A unit set of multiple plies includes superimposed top, intermediate and bottom plies each being devoid of any tear lines which may form a stub, and each being coated on selected surfaces thereof with chemicals which are capable of reacting with one another to produce a colored mark. The top and bottom plies are interconnected by means of a removable glue flap, and portions of the glue extend through holes lying along a margin of the bottom ply so as to thereby interconnect the intermediate and bottom plies together. The top ply is coated front and back and the intermediate ply is coated on its back surface with a micro-encapsulated color precursor, while the bottom ply is coated front and back and the top surface of the intermediate ply is coated with a record-developing material. Upon application of pressure to the set, colored marks are formed on the intermediate and bottom ply top surfaces as the reactive components of the coatings on mating surfaces react.

Abstract: Sets of manifold business forms are coated on selected surfaces thereof with chemicals which are capable of reacting with each other to produce a colored mark. In one arrangement at least one intermediate sheet is coated on one surface with a composition of a record-developing material (which is generally solid) and a non-compatible color precursor (which is generally in the form of a microencapsulated liquid) to thereby function as both a record-receiving and a color-transfer surface upon reacting with the coating of at least another separate sheet of the set containing another compatible color precursor and/or another record-developing material on the surface thereof. In another arrangement, some of the sheets are coated front and back with a record-developing material, while others are coated front and back with a microencapsulated color precursor.
