Abstract: ABSTRACT OF THE DISCLOSURE             A continuous paper web is fed in a longitudinal path.  Glue is applied in transverse strips at regular in-tervals along the longitudinally disposed continuous web over a part only of the width of the web.  A first plow folds over a portion of the web having the transverse glue strips to a position above an adjacent flat portion of the web.  An insert or stuffer is fed into the web between the folded over portion and the flat portion and against an inner crotch thereof formed by the fold line.  The  space between the folded over portion and the flat portion away from the fold is open and forms a wide mouth to readily re-ceive the inserts delivered thereto.  This first folded over portion is then closed down over the inserts lying on the flat portion causing the glue strips to seal onto the flat portion.  The folded over portion and the flat portion of the web contain inserts between each of the transverse glue strips.  A glue strip is applied longitudinally to the web on the flat portion thereof not having a folded over por-tion thereabove.  A second plow acts to fold the longitu-dinally glued flap strip over onto the top of the folded over portion to thereby seal the top of the formed envelope.           The continuous web is then sheared transversely at each transverse glue strip to thus divide the continuous web into multiple individual stuffed and sealed envelopes.

Abstract: APPARATUS FOR THE EVALUATION OF COINS                   ABSTRACT OF THE DISCLOSURE A method and apparatus for evaluating coins on an objective basis.  A support structure displays facsimile coins representative of the obverse and reverse sides of a given class of coins.  The facsimile coins within the obverse and reverse groups are further divided into sets.  Each set contains facsimile coins representative of a particular type of coin defect or imperfection.  The facsimile coins within a set are arranged according to increasing or decreasing extents to which the coin defect is exhibited.  Each of the facsimile coins has assigned to it a number representative of the relative value of the facsimile coin in regard to that particular coin defect.  The obverse and reverse sides of a test coin are compared with the facsimile coins within each set.  The numeric values of the facsimile coins which exhibit the coin defects to the same extent as the test coin are noted and summed to arrive at a total numeric value for the coin.  The monetary value of the test coin is then determined by a table which correlates the total numeric value of the test coin with its monetary value.

Abstract: ABSTRACT OF THE DISCLOSURE      A hermetic electrical terminal construction adapted for connection to the outer housing of a hermetic motor compressor unit so that current may be carried to the compressor motor from an external source.  The terminal comprises a body member welded or otherwise secured to the compressor outer housing and a plurality of conductor pins secured to and extending through the body member.  Each of the conductor pins, which may be made of stainless steel, copper or other suitable material, comprises a first segment disposed within the housing, a second segment disposed outside the housing, and an intermediate segment connecting the first and second segments, the intermediate segment being disposed primarily within the body member.  Electrical insulating and sealing material, such as glass or epoxy potting, surrounds the pin intermediate segment and forms a hermetic seal between the pin intermediate segment and the body member.          The intermediate segment has a larger transverse cross-sectional area than the segment disposed outside the compressor housing with a concomitant larger current carrying capacity so that under irreversible overcurrent conditions, the normal diameter external segment will melt thereby interrupting the supply of current.  Since the intermediate portion is of a greater cur-rent carrying capacity, it will remain intact and the seal between the potting material and pin will not be disturbed so that the pressurized refrigerant within the compressor housing will not be discharged.

Abstract: ABSTRACT A hot-duct system is equipped with heating conductors for feeding molten synthetic material to an injection-mould, preferably a multiple injection-mould with spot-injection for each moulding.  A plurality of hot-duct sections are coupled together in unit-construction style and consist of a housing having at least one inlet- and one outlet-aperture and a heating conductor adapted to be connected to an electrical supply.  The individual heating conductors in the hot-duct sections are adapted to be operated electrically independently of each other.  The unit-construction design of the hot-duct system, in the form of individual hot-duct sections, makes it possible to use the same components, namely the same hot-duct sections, for injection-moulds of totally different designs.  The individual hot-duct sections may also be used to build up a hot-duct system when the original injection-moulds have become worn and must be replaced. Thus full use may be made of the life of the hot-duct sections, independently of the service-life of the injection-mould.  Since each hot-duct section has a heating conductor, which can be operated electrically independently of the adjacent, or some other, hot-duct sections the hot-duct system according to the invention makes it possible to heat up the individual hot-duct sections to different degrees. This permits thermal control of the molten synthetic material in various parts of the hot-duct system.
