Title: Improvements in sewing machine rufflers
IPC: D05B35/08
Filed: 1928-09-19
Abstract: 308,947. Fairweather, H. G. C., (Greist Manufacturing Co.). Sept. 19, 1928. Sewing-machine ruffling-attachments, of the kind in which the ruffle may be made at every stitch or after a varying number of stitches, have a pair of ratchet wheels, relatively adjustable to set the device, and moving together when set. In the example illustrated, two wheels 23, 24 are pivoted on a stud 22 and are relatively adjustable within the limits of the pin 24<c> and slot 23<d>. The wheel 23 has a pair of deep notches 23a and another deep notch 23b. When the wheel 23 is in the position of adjustment shown in Fig. 2, the deep notches 23<a> register with the deep notches 24<a> in the wheel 24. A pawl 26 will therefore fall into these notches and engage the shoulder 16<b>, Fig. 1, to move the actuating lever 16 of the ruffling blade carrier 17 at each six stitches, the pawl being prevented from engaging the shoulder when travelling over the shallow notches 23<c>, 24b. If the wheel 23 is adjusted so that the notch 23b is in register with one of the notches 24<a>, the forward stroke is only imparted to the ruffling blade at each revolution of the wheels, i.e. after each twelve stitches. If a ruffle has to be made at each stitch, the ratchet wheels are lowered by tilting the carrier 20, putting them out of reach of the pawl 26 which therefore strikes the shoulder 16<b> at each stitch. A finger 30 with a lug 30<a> is pivoted on the finger 16<a> to be swung up into the path of the screw 18 to impart a longer throw of the ruffling blade if desired.

Title: Improvements in or relating to separation of acid gases from coal carbonization gases
IPC: C10K1/12
Filed: 1950-11-08
Abstract: <PICT:0675348/III/1> In recovering acidic gases, e.g. hydrogen cyanide, hydrogen sulphide and carbon dioxide, from the actifier vapours of a hot-vacuum-actification process for fuel gas purification wherein the gases are passed successively through a condenser, a vacuum pump, and a second condenser, a solvent oil is vaporized into the gases before entering each condenser and subsequently condenses with any high melting point compounds e.g. naphthalene or phenanthrene in solution therein.  Coke oven gas is treated in scrubber 4 with a countercurrent of aqueous sodium carbonate-bicarbonate circulating in a closed circuit between scrubber 4 at 45-60 DEG C and actifier 12 heated to 55 DEG C under a vacuum of 4 inch mercury.  The recovered acid gases with ammonia, any high melting compounds and an excess of water vapour pass from actifier 12 to condenser 21 at the same pressure as the actifier.  A petroleum distillate boiling at 100-300 DEG C is led from tank 47 by pipe 50 to steam jacketted vaporizer 52 and thence into the gases through pipe 53, before they enter condenser 21. The gases are then passed, to remove ammonia, through scrubber 25 counter-current to water from spray 26 at the same temperature, 35-40 DEG C, as the gases, to prevent water condensation.  The gases then flow to condenser 30 after a further injection of oil from pipe 53, and thence through liquid trap 23 to vacuum pump 33.  The acid gases at 4-12 lb. pressure pass to final condenser 35, after treatment with excess fresh oil vapours through steam jacketted vaporizer 42 and pipe 43, are withdrawn at 36 for refining and separation.  The oil-water condensate from condensers 21, 30 is transferred by pipe 22 to separator 54; the water is separated and passed to tank 56 and may be recycled to make up the alkaline solution from actifier 12 through line 58 while the oil is separated and passed to tank 60 and may be recycled to tank 47 or used as fuel.  The oil-water condensate from condenser 35 is separated in separator 40 and the water is discarded while the oil passes to tank 47.  Live steam may be used to help vaporize the oil.  Condensers 21, 30 may be combined in one condenser with scrubber 25 between it and the pump 33.  The scrubbing liquid in the scrubber may be dilute mineral acid, e.g. sulphuric, hydrochloric, or phosphoric, in closed cycle.  Specifications 190,115, [Class 1(ii], and 612,122 are referred to.
