Patent GB-273721-A (GB)
Abstract: 273,721. National Cash Register Co. July 5, 1926, [Convention date]. Keyboards.-Banks of ledger number or other non-registering keys are divided into two groups, one of which is under the control of the usual automatic releasing-mechanism while the keys in the other group can only be released by a manual operation. Fig. 1 shows a bank of the first group, the known detent plate d receiving at the end of each cycle of operation a clockwise displacement to release a depressed key by means of the shoulder h and the rod i carried by the release-shaft j. In the case of the second group, however, the detent plate hook l, Fig. 2, has no shoulder h and is not rocked by the release-shaft owing to a lost-motion pin and notch connection at p, Fig. 1, interposed between the fast arm k<1> and the arm o<1> supporting the rod n. By means of the usual error-correcting lever the shaft j may be given a counterclockwise movement to a greater extent than that automatically imparted so as to make the rod n effective upon the hook l.

Abstract: 648,572. Hoppers. BRITISH IRON & STEEL RESEARCH ASSOCIATION, and DIAMOND, E. L. Oct. 28, 1948, No. 28013. [Class 78 (i)] [Also in Group XII] In a blast furnace charging device of the conventional double-bell type, the lower bell 3 is movable through the centre of a fixed deflector 18 having an internal annular flange 19 and, as shown in Fig. 3, said bell may be arrested in any one of positions A, B and C, whereby charge material is deflected to the sides, near the centre, or intermediate the sides and centre of the blast furnace respectively. The lower bell rod 10 passes through a hollow rod 5 controlling the upper bell 2, and carries a circular boss 11 which, when position B or C is required, is supported by a pair . of fluidoperated pistons 12 with the bell 3 in a raised position. The lower bell rod 10 also carries a pair of trunnion wheels 13 co-acting with a pivoted arm 14 controlled by a cable 15 from ground level, which cable is used to close the bell 3 with the pistons 12 retracted when position A is required. Release of the cable then lowers the bell to position A, but if position B is required the pistons 12 engage the boss 11 as above, the arm 14 is lowered to its fullest extent tripping a valve to cut off the fluid pressure to said pistons 12 and allowing the bell to fall freely until the boss 11 contacts a crosshead 21 supported by a pair of hydraulically-controlled plungers 22. Position C is attained by raising the crosshead which is pivoted to one of the plungers out of the path of the boss 11 by means of a lever 24 and a cable 25 operated from ground level, thus allowing the boss 11 to fall on to a centrallydisposed hydraulically-controlled plunger 23. Alternatively, the supporting pistons 12, the bell lever 14 and the shock absorbing system may be dispensed with and the upward and downward movements of the bell 2 may be effected by connecting the rod 10 to the piston of a steam cylinder on top of the furnace.

Abstract: 1,011,534. Loom stop device. GEB LOEPFE A. G. July 20, 1962 [July 20, 1961], No. 28097/62. Heading D1E. A stop device for a loom adapted to be actuated by an electric signal derived from a rotary signalling member 2, Fig. 2, engaged and rotated by a moving thread 1. The member 2 may have a builtin magnet 3 which provides a rotating magnet field for co-operating with a coil to induce an alternating voltage therein modulated according to the speed of the member 2. Deviation from a predetermined range of this voltage is utilized in an electronic circuit to act on the stop device of the loom. In Fig. 3 a roller 5 with a magnet 6 is mounted in the loom shuttle 11 and rotated by the weft thread 8. As the shuttle moves along the sley 13 a voltage is induced, through a magnetic conductor 12, in a coil 14 on the sley. If the weft thread breaks the rotation of member 5 ceases and the stop device is actuated through an electrical circuit. The thread 8 is held against the roller 5 by a spring-loaded brake plate 7. Instead of the magnet 6 the rotary member may be provided with a light interrupting device co-operating with a photo-electric cell which produces an alternating voltage in accordance with the rotation of the rotary member. Preferably a trigger impulse is also induced apart from that produced by the rotary member and normally in opposition thereto. Thus, if the weft thread breaks, the trigger impulse is available to actuate the stop device. As shown in Fig. 7 this trigger impulse is obtained by a fixed magnet 28 on the shuttle 24 inducing a voltage in a coil 29 on the sley whilst the rotary member 27 actuated by weft thread 26 induces an alternating voltage in coil 30. The alternating voltage is amplified by a frequency responsive amplifier, rectified and smoothed and opposes the trigger voltage unless the thread is broken or missing when the stop device will operate.
