Inventor: SQUIRE JOHN GASCOIGNE
IPC: F27B3/22
Filed: 1916-02-18
Abstract: 101,998. Squire, J. G. Feb. 18, 1916. Calcining-furnaces; charges, agitating. - In a superposed - hearth muffled furnace for calcining copper ores, having rotary air-supplying rabbles, the heating-tiues beneath the hearths are arranged to produce concentric zones increasing or decreasing in intensity from the periphery to the centre. In a three-hearth furnace, the gases from fire-places 4 pass through two sets of flues 5 beneath the uppermost hearth from the periphery to the centre, as shown by the arrows in Fig. 2, and are then led through flues 6 to the outermost of similar flues 7 beneath the middle hearth. From the inner flues 7, the gases pass through flues 8 to the innermost of flues 9, Fig. 4, beneath the lowest hearth, which they traverse from the centre to the periphery, finally escaping by the flues 10. The ore is fed. near the middle of the uppermost hearth, and thus passes through zones of increasing heating intensity on the first hearth, and of decreasing intensity on the remainder. The four rabble arms 12 in each chamber are carried by a hollow shaft 13 mounted in bearings 14, 15, the latter of which can be adjusted vertically by gearing 53, 54 to raise or lower the rabble teeth relatively to the hearths. The rabble arms are hollow, and their under faces 24 are formed with grooves for the reception of flanges on the tubular T-heads 17 of the rabble teeth 16. The ends of the T-heads 17 abut to form a conduit, through which air is supplied to the ore through passages 18 in the stems or the teeth. Either hot or cold air may be supplied to the calcining - chambers, and to effect this, three two-way valves 26 are provided, by which the supply pipes 22 in the central shaft can be put in communication with a hotair chamber 36 through the dampered conduit 35, annulus 31, and pipe 27, or with a supply fan 29 through the pipes 28. Seals 30, 32, 47 prevent escape of air and gases, and a fourth valve is provided by which cold air can be admitted to the hollow shaft 13 for cooling purposes. This air is heated in traversing the shaft and is supplied to the uppermost chamber through the openings 57. The air supplied to the chamber 36 is heated in peripheral flues 39, 41 beneath the lowermost and middle hearths, and a portion of the air from the flue 41 is led through a vertical passage to an annular flue 43 in communication with the fire-places. The rabble teeth are set at different angles on the four arms for each hearth, and are so arranged that two of the arms neutralize one another so far as the inward or outward movement of the ore is concerned, the third arm moves the ore outwards or inwards according to the hearth, while the teeth on the fourth arm are set radiallv and act as distributors. In a modification, the air-supply fittings are at the upper end of the shaft.

Abstract: 583,227. Measuring continuous lengths of material. TRIGGS, W. W. (Bliss Co., E. W.). Feb. 15, 1944, No. 2803. [Class 42 (ii)] [Also in Group XXII] In a machine for drawing, forming &c. sheet steeb &c. S, the feed rollers 10, 11 driven by an electric motor, are slowed and then stopped, after a predetermined measured length has been fed, by means of switches 87, 88, Fig. 2, operated by a cam 52 to which a torque is applied by an oil-operated motor G, Fig. 4, a shaft 33, and a friction clutch 56, but rotation only occurs as permitted by the rotation of a worm 74, Fig. 1, which is in engagement with a worm wheel 48, fixed to the shaft 33, and is driven by the sheet S through a roller 15 and shaft 70. The clutch 56 is held in driving position by oil pressure in a chamber 53, supplied through a bore in the shaft 33 and a pipe 34, but the switch 88, which stops the electric motor, also cuts off the oil pressure to the pipe 34 and to the motor G, so that a spring 61 returns the cam 52 to its original position. This is determined by a stop 90 on a graduated disc 18 mounted concentric with, and loose on an extension 17 of, the shaft, this disc being adjusted, in accordance with the length of strip required to be fed, by hand-driven worm 82 engaging the worm wheel 84. The cam 52. in returning, releases the switches 87, 88 and thus restarts the electric-motor and reapplies the oil pressure to the motor G and pipe 34. The motor G comprises two pinions 38, 39 in mesh like a gear pump. The ball bearing 36 has a vent to avoid rise of oil pressure therein.

Abstract: <PICT:0832088/III/1> Polyethylene terephthalate is made continuously by mixing dimethyl terephthalate, ethylene glycol and a catalyst in a vessel 1 heated to 145-180 DEG  C. and supplying the mixture via a valve 5 to a U-shaped vessel, the tube 2 of which is heated to 170-190 DEG  C. while the other tube 3 is heated to 197-230 DEG  C. Methanol vapours containing a small amount of ethylene glycol ascend through the pipe 6 and are condensed, the ethylene glycol being returned to the tube 2.  The re-esterification product rising in tube 3 flows through a bridge 7 into a film-evaporator 4 heated to 230-270 DEG  C. and glycol fractions liberated in vessels 3 and 4 return to vessel 2 via a pipe 9.  During the reaction an inert gas is fed into vessels 2, 3 and 4 via pipes 8.ALSO:Polyethylene terephthalate is made continuously by preheating dimethyl terephthalate and ethylene glycol in a first stage to 145-180 DEG  C., feeding the product to a second stage maintained at 170-190 DEG  C., feeding this product to a third stage maintained at 197-230 DEG  C. wherein the reaction mixture is freed from ethylene glycol, feeding the third stage product to a fourth stage maintained at 230-270 DEG  C. in countercurrent to an inert gas and thereafter continuously discharging the resulting polyethylene terephthalate from the fourth stage, the ethylene glycol distilling off from the third and fourth stages being returned to the second stage.  Dimethyl terephthalate (1 mol.), ethylene glycol (2 mols.) and a zinc acetate catalyst are mixed in a vessel 1 heated to 145 DEG  C., and the mixture supplied via valve 5 to a U-shaped vessel, the tube 2 of which is heated to 190 DEG  C. while the other tube 3 is heated to 210 DEG  C.  Methanol vapours containing a small <PICT:0832088/IV (a)/1> amount of ethylene glycol ascend through the pipe 6 and are condensed, the ethylene glycol being returned to the tube 2.  The re-esterification product rising in tube 3 flows through a bridge 7 into a film-evaporator 4 heated to 250 DEG  C. and glycol fractions liberated in vessels 3 and 4 return to vessel 2 via pipe 9.  The polyethylene terephthalate is withdrawn through a valve 10 and may be heated for a short time in the form of a melt or in solvents to produce a spinnable product. During the reaction an inert gas is fed into vessels 2, 3 and 4 via pipes 8.  Specification 578,079 is referred to.
