Title: Improvements in machines for treating textile goods and other articles with liquids
IPC: D06B5/00
Filed: 1921-01-18
Abstract: 172,238. Morgan, E. W. Jan. 18, 1921. Agitating materials and liquids together; vats, heatinq contents of. - A barrel 5 or similar vessel is provided with perforated partitions 15 for showering dyeing or other liquid contained in the barrel on to textile goods &c. retained between the partitions. The barrel is surrounded by a steam-jacket 9 mounted between tubular trunnions supplying to, and drawing off, steam from the jacket, and is rotated intermittently and held stationary by mutilated gear-wheels. In operation, the goods are inserted through a charging-opening 10 in the central chamber provided with supports 22, such as wire-work, to prevent the goods from becoming matted together. The dve is passed through a pipe 36 to the barrel, which is perferably filled to the level of its axis. If the dye is to be heated, steam is admitted through a pipe 26 and valve 27. The mutilated gearing, by rotating the barrel half a turn at a time, brings the dye to the top segmental space 16, whence some of it is sprayed through small perforations in the partition 15 to the goods in the central chamber, while the rest flows through larger and adjustable holes 17 at the ends of the partition and through passages 20 to the bottom segmental space 16, where some of it rises through the bottom partition 15 to immerse the lower portion of goods in the central chamber. The next half-turn of the barrel causes the dye to flow back in the reverse direction. The plates 18, 19 forming part of the side passages 20 may be perforated, and the partitions 15 may have upstanding ribs 15<1> for retaining the dye. A gauge-glass and thermometer are provided on the barrel. The barrel may be used without the supports 22, which may therefore be made removable.

Title: Ignition system for internal combustion engines
IPC: F02P1/08
Filed: 1968-01-22
Abstract: 1,209,691. Ignition generators. AMBAC INDUSTRIES Inc. 22 Jan., 1968 [23 Jan., 1967], 3175/68. Heading H2A. In an ignition system permanent magnets 24, 26 mounted on the flywheel, generate a voltage waveform in winding 34 mounted on E-shaped stator core 33, the positive-going portion being fed over rectifier 42 to charge capacitor 40, Fig. 8 (not shown), while the negative part is absorbed by circuit 44, 46. At a later time, a wave is generated in winding 56, the positivegoing portion of which is fed over rectifier 62 to cause thyristor 52 to conduct, whereupon capacitor 40 discharges through the primary of transformer 10 to develop a voltage in the secondary sufficient to fire the sparking plug 16. Automatic advance.-he winding 58 is reversely wound with respect to winding 56 so that the waveform generated therein has a small positive part followed by a larger negative part, corresponding to the positive part of the wave from winding 56. When the flywheel rotates at a sufficiently high speed, the positivegoing part of the waveform from winding 58 is increased so that it overcomes the Zener voltage of diode 66 and is fed through rectifier 64 to cause thyristor 52 to conduct earlier and give an advanced spark. In a modification. Fig. 7 (not shown), the winding 58 is replaced by a further separate winding (124) and core in advance of the slow speed firing winding (120), and is provided with fewer turns. As a result, it is ineffective until the flywheel speed increases sufficiently for the amplitude of the generated pulses to fire the thyristor (52<SP>1</SP>).
