    Abstract: A web-spooling apparatus for winding a thin web on a core is constructed to control any tendency of the web to telescope. A drive roller rides on the periphery of the web as it winds the web on the core. The drive roller includes web-penetrating radial spikes and has a pair of flanges at the top and bottom which extend radially beyond the spikes and contact the edges of the web should the web tend to move axially off the core. The core is mounted on a spindle in such a way as to permit the core to yaw about the spindle. Contact between the web and a flange causes the core to be yawed about the spindle and thereby provides an angle of small magnitude between the core and web, thus causing the web to move axially in a direction opposite to its first such action, thereby tending to correct the telescoping condition.

    Abstract: BI-DIRECTIONAL, SELF IMAGING GRATING DETECTION APPARATUS An optical position sensing apparatus utilizing a grating having two sets of opaque and transparent lines thereon, one of the sets being off-set from the other is associated with a source-detector assembly, the source and detector assembly including pairs of light sources and detection devices with at least one of the devices of one of the pairs being aligned with one set of light interrupting opaque lines and the other device of the pair being aligned with the other set of light interrupting opaque lines so that the image of the area illuminated by the opposing source is projected back upon the area of the grating in front of its respective detector as by an imaging reflect surface, preferably a concave mirror. Inasmuch as the illuminated areas are of the same phase, the projected images will also be of a similar phase. The grating lines in front of the detectors, however, are 90.degree. off-set due to the off-set of the grating lines. This causes the output signal from the detectors to have a phase relation which will permit direction sensing as to the movement of, for example, the carrier in an ink jet printer.

    Abstract: LIQUID ABSORBING ASSEMBLY An ink absorbing assembly has a first porous material disposed close to a paper against which ink jet droplets impact to print. Ink from an ink mist, which is produced from the droplets striking the paper, is absorbed by the first porous material and then transferred to a second porous material, which is in contact with the first porous material and of a different porosity than the first porous material. This enables the surface of the first porous material adjacent the paper in the print area to be relatively dry so as to not allow airborne particles to cling to this surface. By making the porous material of smaller porosity relatively thick in comparison with the other porous material, a relatively large quantity of ink can be absorbed by the porous material of smaller porosity without the surface of the porous material adjacent the paper in the print area becoming wet before replacement is necessary.

    Abstract: 1284373 Ink ribbon mechanism INTERNATIONAL BUSINESS MACHINES CORP 7 May 1971 [30 June 1970] 13616/71 Addition to 1,183,173 Heading B6F Ink ribbon mechanism includes a drive roller 16 engaging the outer turn of ribbon 12 on a take-up spool 14, the spool 14 being capable of tilting with respect to a spindle 13, and guide means 17, 19 are provided to limit displacement of successive turns of the ribbon axially with respect to the spool. The guide means 17, 19 may be in the form of flanges on the drive roller 16 as shown. The winding mechanism may be employed with thin ribbons in cartridges of the kind described in the parent Specification.
