Abstract: Disclosed is an improved form of a mosaic printer of the bar helix type. The helical raised threads on the printer drum instead of being continuous are broken into segments which are offset axially on the drum. This produces a significant increase in throughput by reducing waiting time for the drum to rotate a section of continuous thread into alignment with a hammer at the start of a new helical pattern.

Abstract: The present invention relates to an assembly of electromagnetic actuators (A, B, C, D, E) for the hammers of an impact printer arranged side by side and extending along a line. Each actuator comprises a first stator part (41) formed with at least one pole piece, a second stator part (42) formed with at least one pole piece and positioned relative to the first stator part so that the pole pieces are spaced apart so as to form a gap therebetween. A single coil (43) is associated with one of the stator parts. Each actuator also includes an armature member (44) formed with a body of non-magnetisable material, at least one armature element of magnetisable material and a hammer head (67). The armature member is supported between the stator parts so that the armature element is located adjacent to the gap. Energisation of the coil causes the generation of a flux which passes across the gap and through the armature element tending to move the armature element into the gap and to cause the hammer head to move into a print position,According to the invention the components of adjacent actuators are complementary in shape so that projecting components (43) of each actuator engage in recessed components (53) of the adjacent actuator whereby the overall length of the assembly along the line is less than the sum of the overall widths of the individual actuators.

Abstract: A ribbon cartridge for an endless loop inked ribbon suitable for use with a wire matrix printer, for example, is disclosed in which the cartridge includes elongated guide members to confine the path of the loop of ribbon outside of the cartridge to a predetermined path and to allow for insertion of the cartridge into a using machine without the necessity of threading inky ribbon through fixed guides on the machinery.

Abstract: A loop of the ribbon passes along the feeler member, emerging at one side from the housing and reentering it on the other. The housing (1) has a fixed guide track (4, 6) for the ribbon (5), having an opening in the front part (6) for the passage of a printing head in the space enclosed by the track and the housing. The tracks can be slightly curved at the front, while components on the typewriter engage in the stiffened corners (12, 30) near the housing and at a point near the front guide, in order to stretch it. Clips (8) can be used to hold the ribbon to the track.

Abstract: A printer is disclosed in which a character forming print head is disposed on a carriage which pivots about a central point to describe an arcuate path, adjacent to which is situated an arcuate platen. The media to be marked upon conforms to the arcuate shape of the platen. The print head oscillates or reciprocates from one end of the arc to the other, and back. The arcuate path length may be varied to encompass printing in one or more coplanar stations on an arc in the plane of the print head and pivot.
