Title: Character type discriminator for character readers
IPC: G06V10/10
Filed: 1972-07-20
Abstract: 1366011 Character recognition systems: reversible counters TOKYO SHIBAURA ELECTRIC CO Ltd 20 July 1972 [21 July 1971] 33983/72 Headings G4R and G4A A character recognition system scans a document carrying two or more frames in each of which characters are written. The characters in a frame are of the same form, e.g. typewritten or hand-written, and a frame containing characters of one form differs from any containing characters of another form. The features distinguishing the frames may be, for example, the frame height. The system determines the nature of the frame being scanned and operates accordingly, e.g. by selecting recognition circuitry appropriate to the form of the characters in the frame. The document is scanned by a flying spot cathode-ray tube and photomultiplier scanner. The photomultiplier output is digitized and fed to a control circuit comprising a pair of counters which control the vertical and horizontal deflection of the c.r.t. beam. The beam is initially moved vertically from a datum point P, Fig. 4, until it reaches the bottom of a mark 18 which is horizontally aligned with the horizontal axis of frame 16. By taking account of the settings of the vertical counter as the beam passes the top and bottom of mark 18 the counter can be stepped back by an amount equal to half the thickness of the mark. The beam is now moved horizontally until the right and left hand edges of the right hand limb of the frame are detected. The beam is stepped back to the centre of the limb and then moved vertically down and up to determine the height of the limb. The circuitry controlling the counters provides a signal (S5 or S8) of duration corresponding to the thickness of the right hand limb of frame 16 or to the height of the limb. A circuit responds to the duration of the signal to select the appropriate recognition circuitry. In a modification a sensor responsive to the colour of the frame is provided, the recognition selection circuit being inhibited unless a frame of the correct colour is sensed. The counters are reversible and comprise a number of JK bi-stables connected in cascade, Fig. 3. The direction of counting is controlled by signals on lines 43, 44. The bi-stables receive clock pulses on line 42. The counter can be set to a required value by energizing line 51 while the value is present on lines 52-1 to 52-4.

Abstract: 1386750 Ships &c. FREDERIKSHAVN VAERFT & TORDOK AS 17 July 1973 [16 Aug 1972] 33990/73 Headings B7A and B7S A vessel's hull 1 is formed with a longitudinal stern well 2 for receiving a train of cargo barges 4 floating on their load waterline. Well 2 is provided with first upper 18 and lower 16 vertically adjustable coupling means adapted to engage second upper 15 and lower coupling means on the barges, and securing means 24, 25, 26 adapted to secure the first coupling means 16, 18 to the hull 1. Each of the first coupling means is mounted on a column 9 vertically slidable in a vertical guide 8 provided in the wall of well 2, each column 9 being connected to an actuating mechanism for raising and lowering the column. The lower end of column 9 includes the first lower coupling means 16 which engages the second lower coupling means when the column is raised, and the upper end of the column includes the first upper coupling means 18 which engage the second upper coupling means 15 on the barge 4 to apply a downward force thereto, whereby the barge 4 is urged against the first lower coupling means 16 of the column 9. As shown, a vessel having a catamaran stern is provided in the walls of the well 2, with vertical guides 8 in each of which a column 9 is slidable by means of a cylinder 14 and cable 10. Each column 9 has a pin 16 at its lower end for engaging an opening in the barge and a socket 18 at its upper end for engaging a pin 15 on the barge. Socket 18 is formed on an arm 19 which is pivoted to the column 9 and is attached to another pivoted arm 20 by a link 21 which is acted on by the piston rod 22 of a cylinder 23 to cause the arm 19 to move from the position of Fig. 3, to that of Fig. 4, in which the barge is clamped between socket 18 and pin 16. The upper rear surface of the column 9 is provided with a toothed bar 24 which may be brought into engagement with a toothed bar 25 on the guide 8 by means of a cylinder 26 thus locking column 9 and guide 8 together. A stern barge 5 with an inclined bottom 6, part of which is adjustable, is attached to the end of the barge train to improve the flow lines of the loaded vessel. In operation, a tug pushes a barge train into the well 2; when the leading barge strikes the wooden buffer 3 a locking mechanism (32), Fig. 2 (not shown), near the stern of the vessel is actuated to prevent horizontal movement of the barges. The columns 9 are then raised by cylinders 14 until pins 16 engage the barges and the cylinders 23 are actuated to cause sockets 18 to engage pins 15. Columns 9 are then clamped to guides 8 by cylinders 26 and are locked mechanically. After the stern barge has been secured in place and the angle of its bottom adjusted, the vessel is ready to sail.

Title: Process for making crimped thermoplastic synthetic linear polymer filaments
Inventor: SPEAKMAN RAYMOND HOLDEN
IPC: D02G1/00
Filed: 1955-11-30
Abstract: Potentially crimped continuous thermoplastic synthetic linear polymer filaments are made by heating moving continuous filaments non-uniformly while passing over a narrow surface heated to a temperature above 270 DEG  C. and above the melting temperature of the filaments, in such a way that they are heated on one side only continuously along their length, while under a tension to give a stretch of not more than 10 per cent.  The latent crimp in the potentially crimped filaments is brought out when they are subjected to a heat treatment under a tension which permits free or controlled shrinkage.  This second heating, which may be carried out immediately after passing over the narrow heated surface or at a later stage of manufacture, is preferably carried out at a temperature above the second order transition temperature and below the melting point of the filaments and may be by treatment with hot inert fluids, e.g. liquids or gases, radio-frequency heating, contact with a heated metal plate or in an oven.  The narrow heated surface, which is preferably convex and with a circular or semi-circular section, may be an electrically heated wire, a pin or a bar.  The filaments, which may be wet, e.g. with a lubricant spin finish, are passed transversely in contact across the narrow heated surface at such a rate that they are heated non-uniformly, with as little change in direction as possible to avoid filament breakages.  Fibre-forming polyamides and the highly polymeric polymethylene terephthalates, as well as copolymers of these containing minor amounts of non-fibre-forming polymers, e.g. polyethylene isophthalate, may be treated.  The filaments may be cut into staple fibres before or after the second heating.

Filed: 1955-12-01
Abstract: 847,605. Valve amplifying circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 22, 1956 [Dec. 1, 1955; Dec. 9, 1955], Nos. 34372/55 and 35360/55. Class 40(6). In a distributed amplifier mismatch is employed in the grid and/or anode lines, in order to obtain increased gain in certain parts of the pass band and decreased gain in others. The arrangement is primarily intended for use as a distribution amplifier, in which desired signals are restricted to a number of bands within the total pass band of the amplifier. In one embodiment, both grid and anode lines are mismatched to their terminating impedances, comprising resistor 32, Fig. 1 and resistive load 14 respectively, and in addition similar phase-shifting networks of known type, 31, 13 respectively are interposed between the lines and their terminating impedances to cause reflections in desired parts of the passband. The anode line is unterminated at its input end. Attenuation of the higher frequencies due to the input resistances of the valves may be compensated by adjustment of the value of the terminating resistance 32 of the grid line: alternatively, positive feedback may be applied from the anode line over a transformer 53. Negative feedback may be applied to the amplifier by means of a condenser 52 connected between the input ends of the two lines. The resonant frequencies of the grid and anode lines may slightly differ in order to obtain a bandpass effect and flatten the response in the regions of increased gain. In another embodiment, Fig. 2 (not shown) the anode line is directly terminated at its output end by a matching resistive load, and reflections are obtained by terminating the input end of this line in a reactive network. The coupling between the anode line 10, Fig. 3 of one stage of distributed amplification and the grid line 54 of a succeeding stage may comprise a phase-shifting network 13 and mismatched load 14, as in the arrangement of Fig. 1, followed by a series reactance 55, the lines 10, 54 being designed to form the two resonant circuits of a bandpass network. The reactance 55 may comprise a line giving the correct coupling reactance within each of the desired bands.
