Patent GB-688525-A (GB)
Title: Process and apparatus for the manufacture of phosphorus trichloride
IPC: C01B25/10
Filed: 1951-08-14
Abstract: <PICT:0688525/III/1> Chlorine gas is passed into liquid yellow phosphorus and the phosphorus trichloride formed is removed as a vapour and liquified.  In a continuous process chlorine is introduced through an inlet 6 into a current of liquid phosphorus circulating in a closed circuit under the the influence of the current of gas and thermosiphon action of the reaction heat. Phosphorus is introduced through inlet 5 and phosphorus trichloride vapour escapes through outlet 7.  Normal atmospheric pressures are generally employed but the vapour may be led off under reduced pressure or with the aid of an inert gas, e.g. nitrogen.  Cooling to prevent conversion to red phosphorus may be effected by the liquid phosphorus passing into the reaction vessel and also by introducing liquid phosphorus trichloride into the liquid phosphorus in the reaction vessel.

Title: Improvements in or relating to closed-cycle gas-turbine plants
IPC: F02C9/24

Abstract: 985,530. Closed circuit gas turbine plant. ESCHER WYSS A.G. May 25, 1962 [May 25, 1961], No. 20229/62. Heading FIG. [Also in Division F4] In a closed circuit gas turbine plant having means for varying the pressure level in the circuit, a storage reservoir is provided for receiving working medium withdrawn from the circuit upon reduction of the pressure level, the reservoir comprising a movable partition which sub-divides the reservoir into two spaces sealed off from each other, one of the spaces serving to store the working fluid of the gas turbine plant, and the other space being filled with a medium which is partly in the liquid phase and partly in the vapour phase for the purpose of varying the position of the partition and so the capacity of the storage space, means also being provided for varying the enthalpy of this medium. The plant shown comprises a compressor 1 in which the working fluid, say helium, is compressed to pressure P1, the helium then passing through a pre-heater 3 and then through a heater 4 before entering the turbine 5. The helium discharges from the turbine at pressure P2 and passes through the heat exchanger 3 where it serves to pre-heat the fluid discharging from the compressor, the helium then passing to the cooler 7 where it is cooled before flowing back into the compressor 1. A storage reservoir 9 is provided being divided by a partition 16 into two compartments 17, 18 of variable volume, the partition 16 being movable between the end positions 16<SP>1</SP> and 16<SP>11</SP>. The turbine circuit is connected to the compartment 17 by lines 11 and 14 containing valves 10 and 13 respectively, the line 11 being connected to the high pressure part of the circuit downstream of the compressor outlet, and the line 14 being connected to the low pressure part of the circuit between the heat exchangers 3 and 7. The compartment 18 of the reservoir 9 contains a fluid such as propane which is partly in the liquid phase and partly in the vapour phase. A heat exchanger device 22 is disposed within the liquid at the bottom of the compartment 18, whereby the liquid may be heated so increasing the vapour pressure, or cooled so decreasing the vapour pressure. For this purpose the heat exchanger 22 is connected by valve-controlled lines 27 and 30 to the cooling water circuit 24, 26 of the working fluid cooler 7. Thus if it is desired to cool the fluid in the compartment 18, the valves 29 and 25 are open and the valve 33 closed so cooling water flows through the cooler 7 and also through the line 30 to the heat exchanger 22 and then discharging through the valve 25 to the outlet 26. If it is desired to heat the fluid in the compartment 18, the valves 25 and 29 are closed and valve 33 opened, the water which has been heated in passing through the heat exchanger 7 then flowing to the heat exchanger 22 before discharging through outlet 34.
