Abstract: An inker for applying ink to a transfer roll of a printing machine has an inking chamber extending longitudinally along the transfer roll and having an outlet also extending longitudinally along the transfer roll and open against the transfer roll and a first generally cylindrical mixing chamber centered on an axis, spaced transversely from and extending longitudinally along the transfer roll. A rotatable shaft extending along the axis in the mixing chamber carries a partition subdividing the mixing chamber into two axially adjacent and axially spaced mixing compartments open radially into the inking chamber. At least two inlet conduits open onto each of the compartments, and a pump feeds respective inks to the inlet conduits and therethrough into the mixing compartments.

Abstract: An extension of an inverse inference search engine is disclosed which provides cross language document retrieval, in which the information matrix used as input to the inverse inference engine is organized into rows of blocks corresponding to languages within a predetermined set of natural languages. The information matrix is further organized into two column-wise partitions. The first partition consists of blocks of entries representing fully translated documents, while the second partition is a matrix of blocks of entries representing documents for which translations are not available in all of the predetermined languages. Further in the second partition, entries in blocks outside the main diagonal of blocks are zero. Another disclosed extension to the inverse inference retrieval document retrieval system supports automatic, knowledge based training.

Abstract: This roll mounting assembly (100) for mounting an anilox roll between opposed sideframes (12) includes an anilox roll (120) and opposed end bearings (124). Each sideframe (12) includes an open ended flanged slot (130) receiving an associated bearing (124) at each end and a screw clamping assembly (140) is disposed at the other end of the slot (130) to apply a predetermined pressure to bearing (124) through the medium of a clamping pad (148).

Abstract: A roller for distributing a coating material such as ink in a press is mounted on a shaft for sliding axially on and rotating on the shaft. First and second internally threaded sleeves are fixed internally of the roller coaxially with each other and concentric to the shaft. One of the threads has a left hand twist and the other has a right hand twist. Two follower plungers, one having left hand thread segments and the other having right hand thread segments are meshed alternately with the left and right hand twist square threads. A link spans between double armed levers which connect to the follower plungers, respectively. When one plunger is automatically forced out of engagement with its cooperating thread in the one sleeve, a force is transmitted through the link to the other lever which causes the other follower plunger and its thread segments to mesh with the internal threads on the other sleeve so the roller changes the direction of its axial movement.

Abstract: A two color printer of the ink roll type which can attain change-over in color with high accuracy with a simple construction. The printer comprises a plurality of type wheels arranged in a row and a pair of ink rolls in which inks of different colors are impregnated. A change-over cam is integrally provided on an end one of the type wheels and has first and second cam sections formed in an axially and circumferentially displaced phase relationship thereon. The ink rolls are carrier on a roll carrier which is mounted for pivotal and sliding movement toward and away from the type wheels and has first and second cam pawls opposed to the first and second cam sections of the change-over cam, respectively, whereby the first and second cam pawls of the roll carrier are alternately engaged with the first and second cam sections of the change-over cam, respectively, to selectively contact one of the ink rolls with the type wheels.

Abstract: There is disclosed printing apparatus composed essentially of molded plastics material which has relatively few parts, is easy to manufacture and maintain, and is lightweight and portable. The apparatus is illustrated as being of the table top type which can print both standard type tags and labels, string tags and pin tickets. The apparatus has a print head operable in conjunction with an impression control device, a feed finger assembly with a registration adjustment, a simple drive arrangement operated by a cam with a single cam path, and a reel positionable at different attitudes, and the construction of the apparatus is readily adaptable to both manually operated and motorized versions.

Abstract: A serial printing apparatus is disclosed which has rotatable and axially slide-movable type wheels and means for supplying differently colored inks to the respective type wheels. The improvement in the printing apparatus made by the present invention comprises the provision of axially slide-movable hammers disposed opposed to the respective type wheels. Printing in different colors is performed by the hammers.

Abstract: A scale printing instrument wherein one or more printing toothed wheels are rotatably held by a tip end of a grip member, an arm is carried by said grip and a brush containing a printing composition such as ink is provided at a tip end of said arm. With this instrument, when the wheel or wheels are run on paper while keeping the wheel or wheels in contact with the paper, the ink is furnished to the toothed wheel to print a scale having given intervals on the paper.

Abstract: A printing device of a construction, wherein a plurality of printing hammers are arranged in parallel facing toward a character wheel provided on its outer peripheral surface with a plurality of character types to be struck by the printing hammers through a printing paper, etc., interposed between the printing hammers and the character wheel, and an ink applying device is kept in contact with the character wheel to apply printing ink onto the type face of the characters, the ink applying device having on its surface discrete sections to apply a printing ink of a color to a particular character to be struck by a particular printing hammer out of a plurality of the printing hammers, and another printing ink of another color to the remainder of the characters to be struck by the remainder of the printing hammers.

Abstract: There is disclosed an ink roller adapted to be used in a printing apparatus. The ink roller includes a hub having a roll-mounting section, a flange section, a first stub shaft adjacent the first flange section and a second stub shaft disposed opposite the first stub shaft and joined to the roll-mounting section. A second flange section telescopically receives and is axially aligned with the roll-mounting section. The second flange section is joined to the hub preferably by ultrasonic welding. There is also disclosed method of making the ink roller.

Abstract: A dichromic ink supply mechanism for use in a hand operated labeler which prints labels dichromically: the ink supply mechanism comprises holding means pivotally attached to a manual actuating lever, two inking rollers respectively impregnated with inks of different colors and both being rotatably and removably carried on the holding means, and guide passages in the frame of the labeler for guiding reciprocating motion of the holding means and the rollers.
