Patent GB-133020-A (GB)
IPC: D03D37/00
Abstract: 133,020. Crespi, S. B. Sept. 21, 1918, [Convention date]. Circular looms.-In a circular loom with electromagnetically operated shuttles, the warp threads between the shuttles 27, Fig. 5, and the poles of the magnets 19 are received in recesses between teeth 21 projecting upwards from the dents of a fixed circular reed 20 on which the shuttles run, so that the warp threads are protected from injury. The reed 20 is made of non-magnetic material, the teeth 21 are backed by a surface 22 welded thereto, and only each alternate reed dent may have a tooth 21. The warps pass upwards from warp beams arranged around the bottom of the loom frame, over and under guide-rods, through a fixed circular reed, and within a circular guiderod to lease rods, whence they pass through healds, operated against the action of springs or weights by eccentrics on a central rotating shaft, and through the reed 20 to a circular ferrule 24 at the lower edge of panels 25 forming a continuous circular surface gradually merging into flat surfaces, between the adjacent edges of which devices may be arranged to form false selvedges in the various pieces into which the cloth is cut. The pieces of cloth are wound on cloth beams driven through reducing-gear from the central shaft, which is driven through gearing by an electro-motor. The ferrule 24 is preferably arranged practically over the teeth 21 so that the inner warp threads are substantially vertical. The magnets 19 are carried by an annular cover 12 running in contact with horizontal and vertical rollers 10, 11 in a brass box 9 filled with oil, and a circular bevel rack 13 on the cover 12 gears with a bevel wheel on a shaft driven by the electro-motor. The magnets obtain electric current through brushes bearing on wire rings over the cover 12. The magnet poles are bent downwards and the magnetic circuit is open. The Specification as open to inspection under Sect. 91 (3) (a) states that the magnets 19 cooperate with soft-iron blocks 28, Fig. 6 (Cancelled), arranged at opposite ends of the curved shuttle and connected together by non-magnetic curved plates 29. At the outer edge of the rod 20 is arranged a soft-iron ring 23 to close the magnetic circuit between the magnet poles, and a soft-iron rib 30 on the shuttle connects the blocks 28 but offers greater magnetic resistance to the magnetic flux than does the ring 23, the arrangement being such that the shuttle is not unduly attracted towards the magnet poles. Better balancing of the shuttle is effected and its displacement prevented by forming the adjacent faces of the blocks 28 and the ring 23 to present obtuse angles towards one another. The shuttle runs on rollers 32 and wires 36 thereon serve to keep the diverged warp threads apart while the shuttle is passing. The beating or closing up of the wefts is effected by a wheel 35 mounted on each shuttle in front of a weft-laying member 34 to which the weft from the cop 31 is led for insertion in the shed at the fell. This subjectmatter does not appear in the Specification as accepted.

Title: Pulse generating systems
IPC: H03K17/54
Filed: 1947-05-19
Abstract: 627,790. Pulsing carrier frequencies. STANDARD TELEPHONES & CABLES, Ltd. May 19, 1947, No. 13405. Convention date, Dec. 30, 1943. [Class 40 (v)] Pulses of high-frequency current of the shape indicated in Fig. 2 are applied to feeders 4, 5 leading to an aerial 6 or other useful load and to a dummy load 7, and switching means are arranged to pass the central portion 13 of each pulse to the aerial, and the initial and final portions 14, 15 to the dummy load. In Fig. 1, the pulse generator 1 interrupts the oscillator 2 to produce high-frequency pulses of the form shown in Fig. 2. At distance gamma/4 from the junction of the feeders 4, 5, branch lines 8, 9 of length gamma/4 are connected and are terminated by valves 10, 11. Normally the grid of valve 10 is biassed to cut-off, and valve 11 is conducting, and owing to the impedance-inverting effect of the lines the aerial line 4 is shorted and the dummy load is energized. Pulses, derived if desired from the source 1, are applied in positive sense to the valve 10 and in negative sense to the valve 11. These pulses occupy the period t1, t2, Fig. 2, with the result that energy flows to the aerial during this period whilst the sloping flank portions 14, 15 are diverted to the dummy load. In a modification (Fig. 3, not shown), the valve 10 is replaced by a spark-gap at the end of the quarter-wave line 8, and another spark-gap is connected directly across the line 5 in place of the quarterwave line 9 and valve 11. These gaps are so adjusted that they break down when the pulse amplitude is above the level represented by t1, t2, Fig. 2.
