Title: Improvements in record material feeding means
IPC: B41L47/24
Filed: 1965-11-09
Abstract: 1,100,428. Feeding webs. PITNEYBOWES Inc. 9 Nov., 1965 [12 Nov., 1964], No. 47472/65. Heading B6B. A record web feeding mechanism comprises an elongated transversely flexible track for guiding the feeding movement of the web, means for selectively advancing and retracting the track away from a work station and means for feeding the record material along the track. As shown in Fig. 4, the web T, which runs perpendicular to the paper is guided in a track comprising a base 21 having at its edges narrow strips 22 overlying the web T. In an alternative form (Fig. 12) the whole of the track is made from plastics material the base being reinforced by springy metal. For easing the passage of the web the base may carry a distinct layer of polytetrafluorethylene, or it and the contacting surfaces 22 may be coated with this material. As shown in Fig. 2, the web and track are mounted within two concentric shells 11, 12 the whole assembly being mounted on a pivot 36 and urged upwardly by spring 37. The web T is unwound from a spool 6 and enters the track at a point just before the track passes through a hole in the inner shell 11. The track is riveted at this point, 26, and then passes along the annular space between the shells 11, 12 before emerging from a hole 27 in the latter. The track then passes under guide means 44 along a work table 2 to the roller 3 of a rotary printing machine or a reciprocatory printer (Fig. 3). The web is fed along the track by a roller 51 which is in contact with the web in the working position. When printing takes place a cam operated lever 60 rocks the shell assembly away from the roller 51 so that web feed is effected solely by roller 3. The track can also be moved to the non-operative position if the button 41 is moved partially to the right to depress the shell assembly sufficiently to disengage the web from the feed roller 51. The inner shell is then rotated to withdraw the track into the annular space between the shells. A full movement of the knob 41 further depresses the shells to allow a door 34 to close to provide a continuous working surface for other types of printing.

Title: Navigation Apparatus
IPC: G02B27/00
Filed: 1967-10-23
Abstract: 1,198,089. Photo-electric navigational apparatus. SINGER-GENERAL PRECISION Inc. Oct.23, 1967 [Oct.27, 1966], No. 48160/67. Heading G1A. In a navigational apparatus for an airborne vehicle a transparency bearing an image of a region of terrain over which the vehicle is expected to fly is positioned in the path of light through an aperture and a photo-detector is arranged to receive the light after it has passed through the transparency and to respond to correlation between the image on the transparency and the actual terrain below. As described the transparency is a cloud loop film strip bearing an image of a strip of terrain across which the vehichle is expected to fly at right angles. The image may be an actual photograph or an image of the most outstanding reflection characteristics e.g. a two level photograph. The apparatus shown allows for the possibility that the vehicle may not cross the strip of terrain at right angles in that the apparatus is mounted on a disc 40 rotatable by a motor 43 to bring the aperture 23 and the film strip 16 in correct orientation with the strips of terrain. The film strip if rapidly advanced across the aperture so that each frame of the film strip passes across the aperture which the vehicle flys over a corresponding area of terrain. When the vehicle flys over a portion of terrain shown on a frame of the film strips the light reflected from the terrain is attenuated least by that frame. This appears as a light spot which traverses a grating 22 giving a pulsating output to a photo-detector 46. This pulsating signal is filtered from the output signal of the photo-detector by a filter 46 and applied to a threshold detector 48 which gives an output indicating that the strip of terrain shown on the film is being crossed. A photo-detector 51 responds to edge markings on the film strip to increment a counter 50 which read when the threshold detector responds to give the particular frame and thus the particular portion of the strip of terrain that is being crossed. The film strip may be two superimposed strips bearing positive and negative images that are laterally offset. This causes two light spots (one light, one dark) to be produced side by side on the grating 22 which as shown is divided into two portions with their opaque strips offset. One spot falls on each portion. The background noise due to reception of light from terrain different from that of the film strip tend to cancel out at the photo-cell while the correlation signals add to produce an alternating signal. In order to obtain a number of different fixes at different points on the flight path a plurality of film strips stored in cartridges may be used or a broad strip carrying several images in parallel may be employed with means for repositioning the strip or the aperture.
