Abstract: In an electrographic printer, a resilient dielectric shield provides contact engagement across a paper sheet moving in synchronism with a dielectric belt at an upstream boundary of a toner transfer zone to prevent the paper which is not yet in contact with the image belt from being exposed to the electric field of a transfer corona.

Abstract: A sealer/conveyor aligns and conveys groups of form sheets, and seals them into form sets.

Abstract: A continuous business form assembly of mailer units, the units of which have slits for accommodating breaker knuckles used in the detaching operation.

Abstract: A business form assembly is provided in which the outer or top sheet is formed with a substantially rectangular window, which must be closed at the completion of the manufacturing stage. To this end, a patch or cover sheet with dimensions slightly larger than the window, is temporarily attached, by pressure sensitive adhesive, to the sheet next adjacent the top sheet but in overlying relationship with the window. The underside of the top sheet is provided with a heat activated adhesive pattern about the periphery of the window and facing the patch or cover. When the form is substantially complete, heat is applied to activate the various lines of adhesive utilized in the form, and including the pattern about the periphery of the window. In this manner, the patch or cover becomes permanently attached to the underside of the top sheet, and is easily removed from the adjacent sheet since the heat activated adhesive is stronger than the pressure sensitive adhesive.

Abstract: Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.). Each module has a main process driver which is not directly coupled to a web drive mechanism. Rather, the web driver is program controlled so as to effect the desired web process at controlled displacement intervals along the web. Accordingly, a plurality of successive but different form lengths or depths can be accommodated as the web surface is sequentially processed. A system of such modules can be physically wheeled into position as individual units and electrically connected together by suitable umbilical cords to rapidly configure a desired overall web finishing process. Nevertheless, the entire ensemble of modules performs as though it is a unitary special purpose web processing machine with its various process stations interconnected and synchronized by an electronic "drive shaft".

Abstract: A bifolded mailer is provided with head and foot panels which are individually shorter than its middle panel but collectively longer than its middle panel. The middle panel is provided with a window flap which remains joined along its lower margin. For variably printing the mailer on one face, the window flap is first folded down so that its outer face is exposed on the inner face of the mailer. After variable printing is applied, the form is processed foot first, in the source of which the window flap is folded back up and patched in place, the head panel is folded up and an insert body is deposited in the resulting trough, the foot panel is folded down, and adhesive bands, which have been applied to various marginal regions of the mailer panels, are activated, for instance by heated platens, creating seals at the left and right ends and in the lap between the head and foot on the outside rear of the mailer.

Abstract: By combining a pad having a repositionable adhesive with a carbonless imaging system, multiple copies of a writing on the top sheet of the pad are provided. These features have application in pads for memos, inter-office correspondence, and notes. A user may select the desired set of copies by removing the required number of sheets from the pad. If a divider is provided with each pad, e.g. a cardboard or a hard insert sheet, the multiple pages are imaged before they are removed from the pad by inserting the divider into the pad after counting the appropriate number of sheets to be copied. Thus, the divider prevents copying and imaging throughout the entire pad.

Abstract: A booklet having a spine constituted by serial pasting of like marginal regions of the pages is provided with a pasting gap at an intermediate site along the spine between two of the booklet pages. An envelope is thereby left with an end margin caught in the pasting gap. In order to ensure that this envelope remains in place until it is intentionally removed, a spot of adhesive is provided between at least one face of the end margin of the envelope and the spine of one envelope-confronting page of the booklet within the pasting gap. The envelope is easily intentionally removed by opening the booklet to the site of the envelope and tugging outwards, away from the spine, in order to sever the localized facial connection of the envelope to the booklet that was provided by the spot of adhesive.

Abstract: An improved process for the production of microcapsules by the use of hydrogen transfer polymerization in the presence of a mixture of emulsifiers including either an aqueous solution of a sodium salt of naphthalene-sulfonic acid-formaldehyde condensate or diphenyloxide disulfonate with a polyvinyl alcohol. The process is particularly useful for the production of microcapsules containing a colorless dye intermediate used in carbonless copy paper (CCP) applications.

Abstract: A return mailer assembly comprising a pair of outer webs and an intermediate web, the first and second outer webs forming a first envelope, and the intermediate and second outer webs forming a return envelope portion, separable from the other outer web. To facilitate and increase the speed of production of such assemblies, a dry-gummed paper stock is sued for one or both of the webs which form the return envelope portion. At least one of the inner surfaces of the return envelope forming webs, as well as an envelope sealing flap portion, are provided with a gummed composition, i.e., a rewettable adhesive. A moisture barrier is applied to preselected areas of one or both of the facing, inner surfaces of the intermediate and second outer webs to prevent activation of the gummed surface, except in peripheral border portions where the return envelope forming webs are joined.

Abstract: A two-part mailer incorporates a conventional return envelope thereinto. The return envelope is affixed to a back side of a first web part that is subsequently heat-sealed to a second web part to form a two-part mailer. The method of assembly has a step in which the return envelope is affixed to the back side of the first web part in such a manner that the return envelope will not interfere with a glassing patch and/or die-cut area in the first web part nor interfere with removal perforations along the web part nor cause excessive bulk in areas where the first web part is heat-sealed to the second web part to form the two-part mailer.

Abstract: In a web-type multiple-part business form stock having a succession of serially connected potential outgoing envelopes each containing one or more intermediate layers which may be withdrawn from the outgoing envelopes after the outgoing envelopes are received and opened by an addressee, the hitherto conventionally-used cross-web lines of cold glue used for defining the two opposite edges of the internal spaces of the potential outgoing envelopes is replaced by cross-web band patterns of hot melt adhesive applied in a customary location, but left attached only to the web surface to which it was applied, and which is not heat activated and used to adhere the respective webs together until after the form stock has been variably printed by the form manufacturer's customer, e.g. by an impact printer used in association with a carbon-type or carbonless between-layers coating provided internally of the form stock.

Abstract: This invention is concerned with a business forms assembly system for medical use, particularly in hospitals, which are capable of being able to record a medical test, for example, a blood test, which assembly comprises a backing sheet with one part of the backing sheet having a transparent sheet secured thereto to provide a bag to contain a medical sample and another part thereof intended to receive information about the medical sample. The system also utilizes a retainer for supporting the bag containing the medical samples.

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 which, except for the initial mail-to address, has an upside-down orientation relative to the mailer. The recipient then turns the return envelope right-side-up which places the initial mail-to address in the upper left hand corner, upside down, as a from address, and places the return mail-to address (which was formerly hidden, in an inverted orientation, by the cover sheet, right-side-up in a customary position. 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 mails it back.

Abstract: A security document having first and second areas on one side coated or treated with complementary compositions of the types that will leave a mark when pressed together, with some areas of one composition desensitized, so that the authenticity of the document may be tested by folding the document to place the areas together and then exerting pressure thereon.

Abstract: The business or other institution is provided with two complementary series of blank form parts. One of these contains one or more elements of a form of construction (multiple ply, window, glassine-patched window, glue spots, patches or strips) which would make it incompatable for use with today's commercially predominate non-impact printers. The other contains none of such elements and is suited for being run through a business computer-controlled non-impact printer for the purpose of printing of variable information thereon, and of being thereafter assembled and united increment for increment with form parts from the first series, using presently available assembling and uniting apparatus, whereupon the united forms may be successively severed into thus individualized communications and dispatched to their respective addresses.

Abstract: A pad is provided of a stack of preprinted sheets grouped set by set in at least one set, at least some sheets of which differ in some way from the others by virtue of the information, indicia, routing indicator, pattern of carbonless back-coating, color or the like. Within the pad, each sheet is serially connected to its neighbors along at least one respective margin of each, at least one of these connections in each set being by means of a strip of non-drying, lightly tacky pressure-sensitive adhesive, e.g. so as to provide a multiple part business form set or a pad of several multiple part business form part sets stacked in series, in which at least some of the sheets are connected to adjacent sheets at least generally in accordance with the way that is disclosed in Swiss Pat. No. 452,479.

Abstract: For providing an improved mailer/return envelope/remittance stub assembled set in which the remittance stub and check may be inserted by the consumer in the return envelope without folding either of them, which return envelope and contents may be sorted and read, if desired, by automated machines, and as to the parts of which the business may use a combination if impact and non-impact printers to print variable information on the parts prior to assembly, and use a relatively inexpensive sealer for assembling the parts into sets, three parts are provided. Of these, Part 2 at one stage forms a first face of a mailer and at another a second face of a return envelope; Part 1 at that other stage forms the first face of the return envelope and the flap for sealing the open end of the return envelope; and Part 3 at the one stage forms the second face of the mailer and, at the other stage, forms the remittance stub.

Abstract: Each unit of the stock for a match-the-hidden-indicia game includes a base sheet printed on one face with a visually ascertainable pattern of indicia, and a cover sheet also printed on one face with a visually ascertainable pattern of indicia which may or may not match the pattern on the base sheet. The one face of the base sheet on at least a band including the pattern of indicia, is provided with a transparent coating of permanent adhesive, and a liner layer is facially adhered thereto. The relative attraction of the permanent adhesive for the one surface of the base sheet and the liner layer is such that any attempt to remove the liner layer will substantially disrupt the one surface, thus giving evidence of an attempt to tamper with the pattern of indicia on the base sheet.

Abstract: A pad is made up of sheets adhered one to the next by a releasable adhesive in which the adhesive is distributed on the sheets over more than a minor area of the sheets to more positively hold the sheets down on a surface to which applied, but retaining free edges to facilitate lifting off of the sheets by the user.
