Title: Improvements in the manufacture of phosphorus oxychloride
IPC: C01B25/10
Filed: 1958-11-20
Abstract: <PICT:0893096/III/1> Phosphous oxychloride is produced in a continuous process by introducing phosphorus trichloride and a gas containing free oxygen separately into a liquid heel composed of POCl3 and unreacted PCl3, the POCl3 being present in the liquid heel in an amount of at least 70 wt. per cent at all times throughout the process.  The reaction is carried out at 15 DEG -70 DEG C. and atmospheric to 30 p.s.i.g. pressure with air, O2-enriched air, or O2. The liquid heel is withdrawn from surge tank 1 (whence product containing 80-90% POCl3 is withdrawn at 8), through 2 by circulating pump 3 and PCl3 is added at 5.  O2 is added to the discharge at 6 and the mixture passes through water-cooled pipe reactor 4.  The volume ratio of liquid to gas at the inlet 6 is 2/1 to 4,2/1, and the time in the reactor is 0,05-0,5 mins.  The reaction mixture is returned to surge tank 1.  The flow in the pipe reactor should be turbulent and the minimum liquid velocity in the first 5-8 vol. per cent of the reactor should be 8-11 ft./sec.  Velocity in the remainder of the reactor is 4-6 ft./sec. and this difference in flow velocity is obtained by variation in pipe diameter.  A simple heat-exchanger jacketed reaction kettle equipped with an agitator (Fig. 1, not shown) is also described where PCl3 is fed in just below the surface of the liquid heel, and O2 is fed in through a distributer at the bottom.  Specification 727,950 is referred to.

Abstract: 523,066. Repeating systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 23, 1938, No. 37461. Convention date, Dec. 27, 1937. [Class 40 (iv)] [Also in Group XL] In a carrier telephone system in which signals, e.g., dialling signals, are sent by means of the carrier, which is suppressed during speech, the signal currents traverse only a part of the channel filters. As shown, each channel has at the transmitting end a filter section Fl which passes the side-band but not the carrier frequency currents and a filter section F2 which passes both, and the signalling connection is made between these sections. The receiver is. connected between a similar pair of filter sections F4, F3 and includes a filter F5 sharply tuned to the carrier frequency. Fig. 2 shows a preferred form of filter. Preferably the filter sections have a high input impedance looked at from the point at which the signal circuit is connected since this enables the coupling transformer 9 to be replaced by a resistance 11.

Inclusions in a hot workpiece are detected by determining the temperature difference between two locations on the workpiece. The investigation which may be by remote infra-red detectors is carried out whilst the metal is still hot after for example volting. The locations may be relatively transverse to the direction of motion, in line longitudinally, or, one on each of opposite faces. The workpiece may be force cooled by air or water to accentuate the difference from a spot in which the heat flow to a cooled area is reduced by an inclusion. Temperature measurements may be taken on a running strip above and below trowelwise of the area of cooling. Differences above or below a predetermined level, according to the system used, may effect a cutting control or give an indication. More than two locations may be investigated to detect for example both pipe inclusions and edge faults.
