Abstract: 1,109,994. Character recognition systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 17 Sept., 1965 [17 Sept., 1964], No. 39690/65. Heading G4R. A circuit identifies to which of a number of fields characters represented by a pulse train belong, by reference to special pulses one of which is generated at the commencement of each field, each special pulse not specifying an individual field, and comprises a stage for each field, each stage comprising a bi-stable switched on in response to a particular one of the special pulses either when there is no lower order stage responsive to the same special pulse or when the bi-stable of any stage between the highest such lower order stage and the preceding stage inclusive is on, the highest order stage of which the bi-stable is on representing the field. During the reading of a bank cheque, four special pulses delineating the fields may be produced on respective lines, some more than once. A replaceable printed circuit card (or permanent wiring or plugs) in each stage causes it to be responsive to a pulse on a particular one of the four lines, to switch the bistable in the stage on only if (a) there is no lower order bi-stable responsive to the same special pulse line which is off and not of lower order than some bi-stable which is on, and (b) neither the bistable in question nor any higher order bi-stable is at present on. Any stage may be effectively ignored (in. hibited). An error indication is given if the highest order bi-stable corresponding to a given special pulse is on and the same special pulse then occurs again. Switches are provided to by-pass the printed circuit card (or &c.) to utilize permanent wiring, for testing purposes. A modified lowest order stage is described in which an auxiliary bi-stable produces a signal identifying the first field on detection of the first character if the special pulse which should precede the character signals from the first field is missing.

Title: Combined traversing and thread-cutting mechanism for lathes and like machine tools
IPC: B23G1/04
Filed: 1959-11-25
Abstract: 869,325. Screw-cutting lathes. ETABLISSEMENTS A. CAZENEUVE, and BRUET, H. R. Nov. 25, 1959 [Dec. 16, 1958], No. 40086/59. Class 83 (3). A combined traversing and screw-cutting mechanism for a lathe or like machine-tool comprises a lead-screw 1, Fig. 2, driven by the usual change-speed mechanism (not described) engaging a worm-wheel 6 secured to a crossshaft 8 in the saddle apron 5. A pinion 7, secured to the worm-wheel, drives a pinion 9 on a parallel cross-shaft 10 and one of a number of gears 11, 12, &c. may be keyed to rotate with this shaft and drive a wheel-block 18 at different speeds. The wheel-block 18 is loose on the shaft 8 and integral with a number of discs 19, 20 provided with recesses on their peripheries (see below). The wheel-block 18 drives gear 23 fixed on a further cross-shaft 24. The latter has, slidably keyed to it, a dogclutch member which can be moved by a handle and rack pinion gear to engage, either, a pinion 25 which drives a wheel 26 and pinion 28 for the rack-and-pinion saddle traverse, or, a gear 30 which drives a pinion 31, Fig. 3, keyed to the cross-slide screw 32. With the dog-clutch in the neutral position, a lever 63, Fig. 1, may be depressed which, through a torsion spring, moves a bell-crank lever 49, 50, so that a roller 48, on the end of the lever, engages one of the recesses in one of the discs 20, 21, &c. The bell-crank lever may be shifted laterally to select a different disc by moving a knob 52, Fig. 2. Engagement of the roller 48 in a recess holds the discs and gearwheels 11, 12, &c., against rotation so that the worm-wheel is also held and thus acts as a nut in co-operation with the lead-screw for screw-cutting operations. The employment of the discs with different numbers of recesses enables the threading mechanism to be reengaged for further cuts ensuring the proper positioning of the lead-screw and worm-wheel. A disc is selected in conjunction with the pitch of the thread being cut and according to which of the gear-wheels 11, 12 is employed. A stop (not shown) brings the saddle to rest at the end of the thread cutting and the worm wheel and disc selected then commence rotation and slip past the roller 48 which is pushed out of its recess. Release mechanism is operated simultaneously to withdraw the cross-slide a distance d, Fig. 3, to remove the tool from the cut. A gauge 82 is set to give the desired relief d and when the lever 63 is moved to start threading a lever 77 is moved to compress a spring 75 in the cross-slide and a catch 72 slips over a collar 73 to hold the spring and cross-slide. When the roller 48 is pushed out of its recess at the end of a thread-cutting operation the catch 72 is tripped by the movement of the bell-crank lever. Cuttings, catching. The lead-screw is supported close up to the worm-wheel by roller bearings 2, 3, Fig. 10, and the whole screw is protected by telescopic covers 90-92 and 93-95 arranged at each end.

Filed: 1974-09-18
Abstract: 1479968 Selective signalling FERRANTI Ltd 15 Sept 1975 [18 Sept 1974] 40663/74 Heading G4H In testing system, inputs are scanned under control of a train of pulses sent over a single wire from a central unit at which the pulses are also counted to control input-indication means when a predetermined-condition-detected signal arrives over the wire from a scanned input, the signals sent in the two directions being interleaved. In order to monitor circuit faults, the central unit sends clock pulses over the wire to a scanner, the pulses being counted at the scanner and at the central unit. The count at the scanner is decoded to scan fault sensor gate. If a gate is receiving a fault signal when it is scanned, it sends a pulse via a respective resistor and the wire to the central unit to cause the current count at the the central unit to be displayed, the production of clock pulses being slowed briefly. One of the sensor gates has a permanent "fault" input and a smaller resistor, to produce a larger pulse on the wire which resets the counter at the central unit, thus synchronizing it and the counter at the scanner. To distinguish absence of faults from malfunction of the system, the reset pulse may be used to flash a decimal point indication in the display or another lamp. As a modification, groups of fault inputs may be scanned, the inputs of a given group being scanned individually only if one of them is signalling a fault condition. A plurality of scanners may be provided, linked to the central unit via respective wires and a selector switch.

An apparatus for stretching and thereafter heat setting under controlled shrinkage conditions artificial filaments comprises a pair of positively driven feed rolls 2 which feeds a monofilament or multifilament yarn 1 to a snubbing pin 3 and thence to a positively-driven draw roll 4 rotating at a peripheral speed several times that of the feed roll 2. The thread travels in several helical turns 6 round the draw roll 4 and a freely rotatable thread advancing roll 5 driven by the thread. The thread then travels upward from the roll 5 over and in sliding contact with a convex surface 7 of the stationary heating member 17 to a tapering or frusto-conical second thread advancing roll 8 from which it travels downwards over and in sliding contact with the convex surface 9 of the heating member 17 to the roll 5 from which it again travels upwards over the surface 7. The thread continues to travel in this manner and to advance in a series of helical turns 9<SP>1</SP> over the rolls 5 and 8 and the heating member 17. The thread then leaves the smaller diameter end of the conical roll 8 and travels by way of a traversing device 10 to the packaging bobbin 12 driven by the friction roll 13. In travelling over the surfaces 7 and 9 of the heated member 17 in the series of loops 9<SP>1</SP> the thread becomes heated to a predetermined temperature and is thereby caused to contract or relax to an extent determined by the degree of taper of the roll 8 towards its delivery end. Instead of travelling directly from the roll 8 to the wind-up bobbin 12 the thread may be caused to travel from the roll 8 to a second draw roll and a thread advancing roll co-operating therewith and thence to a ring-twisting device.
