Title: Digital data coding system
IPC: B41B27/00
Filed: 1970-10-30
Abstract: 1328266 Cathode-ray tube displays; facsimile systems INTERNATIONAL BUSINESS MACHINES CORP 30 Oct 1970 [4 Nov 1969] 51646/70 Heading H4F and H4T In a photocomposing system in which typographical images are produced on the screen of a cathode-ray display tube (and recorded on photographic film) under the control of a digital data code derived from a remote location or from a computer the code is produced in a "compressed" form by employing run-length coding for both the X and Y co-ordinates of each image the "compressed" code being "expanded" for controlling the production of the display. Thus, the lower case character "e" shown in Fig. 2 is coded in terms of the grid pattern (in practice a much finer grid is employed) by initially deriving a count (counting upwardly from the bottom of the grid) of the number of bits in vertical column 4 of the white portion of the display, i.e. 13 bits and a count of the number of bits of the black portion of the display (the first vertical segment of the character), i.e. 7 bits. Vertical column 5 is then analysed and a count of the difference between the white and black portions, i.e. - 3 and + 5 respectively is derived. Vertical columns 6 and 7 are analysed in similar manner giving count differences of - 2, + 4 and - 1, + 2 respectively. When, however, the number of White-Black transitions changes (columns 4 to 7 each have two such transitions whereas column 8 has four and column 9 has six transitions) it is necessary to derive a full count of the bits, i.e. column 8 has 6, 7, 3, 10 and column 9 has 5, 6, 5, 3, 2, 6 after which difference are produced for columns 10 to 24 all of which have six transitions. Column 25 which has four transitions is derived in a full length count 6, 6, 4, 10, columns 26 to 28 as difference count and columns 29 which has two transitions as a full length count 16, 4. Character data coded in the manner described is stored in a computer 10 (Fig. 1) and when required is sent to a data expander 12 in an eight bit per byte binary code the expander and the display control 13 (detailed in Fig. 3, not shown) supplying the beam blanking and unblanking signals which are required to reproduce successively the vertical column 4 to 29 of Fig. 2 during successive fixed position vertical scans on the display tube 14 the horizontal positions of each column on the photographic film 16 being controlled by a moving lens responsive to display controls 13. The detailed operation is described.

Abstract: 1,186,487. Tentering fabrics. BEVIS INDUSTRIES, Inc. 31 Oct., 1968, No. 51650/68. Heading D1S. [Also in Division F2] A two-speed belt drive, especially for a tentering machine, consists of a low ratio train incorporating a one-way clutch, and a high ratio train operated by a friction clutch, the one-way clutch permitting overrunning of the driven shaft when the higher ratio is engaged. As shown a motor pulley 140 drives a pulley 112 on a main shaft 100 which in turn drives two half shafts 101, 110. The normal low speed drive is taken through pulleys 113, 116, and 146, 146A incorporating one-way clutches 135, 135A, while the high speed drive is taken through pulleys 128, 117 and 132, 132A incorporating pneumatic friction clutches 125, 125A. Pulleys 136, 136A on shafts 101, 110 may drive overfeed mechanisms 75, Fig. 1 or, as shown in Fig. 4, the shafts may drive the sprockets 25, 26 of the tenter clip chains through bevel pinions 214, 215. In the event of skew correction being required the appropriate clutch 125 or 125A is engaged to increase the speed of the desired half shaft 101 or 110, the associated one-way clutch 135 or 135A permitting overrunning of the shaft.

Abstract: 1364346 Tape splicing machine KING INSTRUMENT CORP 13 Nov 1972 [4 Oct 1972] 52349/72 Heading G5R [Also in Divisions G2 and B5] A tape trimming and splicing machine comprises two splicing blocks 30, 32 for supporting two sections of tape, the tape ends initially projecting beyond confronting, spaced faces 45, 47 of the blocks, and a cutter assembly 10 which is passed between the blocks to cut off the projecting tape ends, the blocks then being brought together, Fig. 6, so that adhesive splicing tape may be applied to the joint. The blocks are then separated and the cutter assembly 10 withdrawn therebetween to lift the spliced tape therefrom. The splicing head 8.-The blocks are reelprocable horizontally together and apart on rods 22, (24), Fig. 2 (not shown), by pneumatic actuators (34, 36). Each block has a groove (54, 56), Fig. 4 (not shown), in which tape is held by suction through openings (60). The cutter assembly 10 comprises two cutter blocks 78, 80, Fig. 6, rotatably mounted on a block 72 which is recipricable vertically between the separated blocks 30, 32 by a pneumatic actuator 66. Cams 82, 84 rotatable with the cutter blocks 78, 80 engage guide surfaces 86, 88 to ensure that the blocks 78, 80 initially adopt the tilted positions of Fig. 1. During the cutting operation, cutting faces 78A, 80A strike the blocks 30, 32 and are rotated to the parallel position of Fig. 6. A resilient pad 96 limits the descent of the assembly 10. A splicing tape dispenser/applicator unit 12 may be included, which is reciprocable vertically on rods (128, 130), Fig. 2 (not shown), by a pneumatic actuator (144). The splicing tape 172, Fig. 7, is advanced from a reel 170 by means of a one-way clutch 184 actuated when the unit 12 is lowered by rotation of an arm 188 located between pins 260, 262. The tape 172 then projects into a channel 225 through a slot 256. A plunger 238 is then lowered in the chinnel 225 by a pneumatic actuator 228, and a cutter 244 thereon severs the projecting tape 172, which is then held against a resilient pad 246 on the plunger bottom by suction applied through holes 250, until the tape 172 is applied to the joint. A unit 14, which includes a roller 118 mounted on an actuator 100, may be provided for pressing the splicing tape on to the joint, the roller 118 being lowered on to the block 32 upon clockwise rotation of the actuator 100 by a further actuator 112. The actuator 100 then extends to roll the roller 118 across from block 32 to block 30. Automatic sequential operation of all the actuators is achieved by a plurality of cams (282A-282G), Figs. 9, 10 (not shown), driven by a single motor (280).
