Abstract: The recipient of a mailer, following pre-printed instructions, severs a marginal portion in order to separate a cover sheet, through a window of which the initial mail-to address label was visible, from a return envelope. The recipient then detaches a remittance document from the separated cover sheet and places it in the return envelope, e.g. together with a bank check or other form of payment, seals the return envelope and peels off the initial mail-to address label, thus exposing the pre-printed return mail to address. The peeled-off label is to be re-applied up in the upper left corner sender's return address position. The initial mail-to address label and the underlying return mail to address may be provided on the respective layers of a so-called piggyback label.

The assembly comprises, second, a longitudinally spaced series of form sets attached to the carrier form stubs. The carrier web further includes spacer sheets alternating with the carrier form stubs. The spacer sheets provide leaders for printer feed tractors, for small quantity computer printer users.

Abstract: A label showing insurance data or the like having a transparent film attached thereto by a first adhesive layer between the label and the film, and a second adhesive layer on the opposite side of the film for attaching the combined label and film to the inner surface of a glass pane of an automotive vehicle.

Abstract: A carbon security system is provided for a customer using a credit card to get all of the carbons when the customer copy is taken. Security is achieved because all carbons are connected to the customer copy and are removed together with the customer copy. A set made up of the customer copy and all carbons may be folded over so that the carbons are left inside of the folded customer copy. A strip of adhesive attached to the top side or underside of the stub retains the folded set together. Thus, there results a very good way for the customer to retain the carbons without getting a mess on his or her hands and without risking fraudulent use of credit card data obtained from the carbons.

Abstract: An identification band, particularly suited for use in hospitals or the like, comprises a single elongated strip of non-irritating material having an adhesive coating on one surface, and being adapted to receive data on the opposite surface. The strip is foldable about a centrally disposed longitudinal axis and, on one side of the axis is separable into a relatively short tab component at one end, and a relatively long body component extending to the other end, so that the body component may be folded about the axis to bring its adhesive surface into contact with the adhesive surface on the opposite side of the axis to form a relatively thin band component, the free end of which may be brought into overlapping relationship with the adhesive surface opposite the tab portion, with the tab portion then being bent over to bring its adhesive surface against the free end of the band portion in order to complete a circular band.

Abstract: A two-dimensional coordinate measuring pad for use, for example, to recognize handwriting. A high resistivity sheet is bounded by a lower resistivity border connected to a switched voltage source to cause a current to flow first in one direction and then in a perpendicular direction through the resistive sheet. Potential measurements at an array of precisely predetermined points are employed to generate a set of correction values which are stored in a programmable read-only memory. Thereafter, to indicate the position of an arbitrarily selected contact point on the sheet, the stored correction values for the nearest points are fetched form the memory and combined with the measured values to produce adjusted output values which more accurately indicate the positional coordinates of the contact point.

Abstract: A continuous business form assembly of a plurality of webs is disclosed. Two webs form a series of envelopes. Other webs form envelope inserts substantially free and loose in the envelopes. The inserts are joined to the assembly through only abbreviated tear tabs which are behind envelope tear strips and joined to insert web attachment strips formed into the envelopes.

Abstract: A continuous, filled envelope assembly includes continuous, envelope forming webs and laterally abbreviated insert webs. The insert webs are capable of accurate feeding with the envelope webs, and also adapted to be processed independently, and include a row of spaced feed holes of one web superimposed on a non-marginal row of spaced feed holes of an adjacent web.

Abstract: A chromogenic mixture capable of forming a black image with zinc-modified phenolic resins is disclosed that includes an orange chromogen, a green or single component black chromogen and a blue, indigo or violet chromogen.

Abstract: A carbonless system having improved imaging characteristics by the use of microcapsules containing only solvent is disclosed. The solvent-only capsules are disposed within a carbonless system to enhance the resulting image without the use of additional dye precursor.

Abstract: A two-way envelope has a front and rear surface formed of a single rectangular sheet folded upon itself about a transverse central foldline. The envelope comprises overlying front and rear return envelope panels, overlying front and rear data bearing panels, and front and rear transverse lines of separation parallel to the central transverse foldline and separating the return envelope panels from the data bearing panels. The transverse lines of separation are offset to define on one surface of the envelope a return envelope flap adjoining one of the return envelope panels by a line of weakness. Adhesive is disposed on the inner surface of the return envelope flap, and sealing means secures the three free edges of the two-way envelope about the central foldline except those portions of the edge coincident with the return envelope flap.

Abstract: A method of forming microcapsules by in-situ polymerization is disclosed. The microcapsules are prepared by forming an organic solution containing a polyfunctional amine curing agent and an epoxy resin select from the group consisting of 4-glycidyloxy-N, N-di-glycidyl aniline and methylolated bisphenol A based epoxy resins. This organic solution is then dispersed or emulsified within an aqueous continuous phase. The amine agent then polymerizes the epoxy resin, which migrates to the interface between the continuous and discontinuous phases to form the microcapsular wall. The resulting microcapsules are characterized by relatively high impermeability and are especially useful in carbonless copying systems.

Abstract: A serrated rotary die having a minimum die cutback angle .theta., wherein ##EQU1## where CL DIST is the centerline distance between punch and die axes of rotation, ##EQU2## MD is a die internal diameter at the die teeth roots, and HT is the height of the die over midpoint.

Abstract: In the perforation of webs, such as in the perforation of paper webs in the production of business forms, a single perforating cylinder is utilized in cooperation with two anvil cylinders. Perforating elements, such as interrupted blades, extend outwardly from the periphery of the perforating cylinder and are rotated into operative association with the web passing between a first anvil cylinder and the perforating cylinder, and a second anvil cylinder and the perforating cylinder, to form first and second sets of perforations spaced a predetermined desired amount along the web. The length of the web between the first and second anvil cylinders is adjustable to control precisely the spacing of the first and second sets of perforations along the web, as by passing the web over a compensator roller mounted between the first and second anvil cylinders and movable toward and away from the perforating cylinder.

Abstract: A method of microencapsulation is disclosed whereby two or more organic-in-aqueous emulsions, each containing a reactive component in the organic phase, are mixed together causing the reactive components to react and form polymeric walls around the organic droplets. Either, neither or both emulsions may contain one or more fill materials in their organic phases.

Abstract: A continuous business form assembly provides for printing internal and external information on a single web in one, single-sided printing operation.
