Title: Improvements in or relating to mass spectrometer leak detectors
Inventor: HALL LEWIS DANA
IPC: G01M3/20
Filed: 1968-11-26
Abstract: 1,245,153. Ion pumps. L. D. HALL. 26 Nov., 1968 [29 Nov., 1967], No. 55987/68. Heading HID. [Also in Division G1] A mass spectrometer leak detector system includes a high vacuum pump comprising a source of getter material 68A, 68B disposed within the main space 64 of an evacuable chamber 61 with a filament 69 for vaporizing the getter material on to the chamber walls 65 to absorb gas molecules coming into contact with the walls and, within an auxiliary space 76, cathodes 77A, 77B are disposed, in such a position that they have getter material from source 68A, 68B continually deposited thereon, and maintained at a negative potential with respect to the chamber walls, with a magnetic field 79 between the cathodes 77A, 77B such that gas molecules are ionised by the spiralling electrons and the positive ions created are absorbed on the cathodes and buried there by the continual getter deposition. Non-noble gases may be removed by the getter on the main chamber walls 65 and noble gases, e.g. helium which is very often the probe gas used in leak detection, are removed when they are ionized in the auxiliary space 76. The relative pumping rates of noble and non-noble gases is determined by the ratio of cathode area to main chamber wall area. The getter, e.g. titanium, need not be sublimed by electron beam bombardment from shielded cathode 69 but may, for example, be heated in an arc. The cathodes 77A, 77B may be of titanium but are preferably of iron. In the mass spectrometer leak detector system, Figs. 1 and 2 (not shown, see Division G1S, the high vacuum pump is used to obtain a pressure of about 10<SP>-6</SP> Torr in the mass spectrometer region. For the remainder of the high-vacuum system including the vessel under test the vacuum, e.g. of 10<SP>-3</SP> Torr, is produced by a mechanical roughing pump.

Abstract: 1,213,486. Ammoniation of acids. OCCIDENTAL RESEARCH & ENG. L t d. 11 Dec., 1967 [20 Nov., 1967], No. 56297/67. Heading ClA. [Also in Division B ' - In the ammoniation of acids, particularly phosphoric acid, by a fast chemical reaction, a mixture of the reactants, e.g. H 3 PO 4 , NH 3  and H 2 0, is formed and at least a portion of one of the reactants is allowed to react completely within a reaction period to form steam and a reaction product e.g. ammonium phosphate and ammonium polyphosphate. The steam is used to propel the product through and expel it it from the reaction zone. The product is then cooled e.g. by counter-current heat exchange with air. In the embodiment shown in Fig. 1 phosphoric acid, anhydrous NH 3  and water are admitted into reaction vessel 1 through conduits 2, 3, 4 respectively. The product is discharged into cooling tower 6 where it is cooled by a counter-current of air supplied by blower 7, and is then discharged into receiving vessel 9 and transferred to storage through conduits 10, 11. Ammonia is fed in through inlet 14, heat exchanger 13, valve 16, meter 17 to the inlet of reaction vessel 1. Water is fed to the inlet of conduit 30 through valve 32, meter 33 to reaction vessel 1. The NH 3  and acid can be admitted in the correct proportions to obtain a product having the desired pH, or a portion of the product may be routed through conduit 19, pH meter-controller 20 and conduit 21 back to receiving vessel 9. Valve 99 in conduit 15 is actuated by means 22 in response to an output signal from pH meter controller 20 and thus the flow of NH 3  is controlled. The specific gravity of the product can be controlled by regulating the flow of water through valve 34, which is controlled by actuator 35, which is responsive to the output signal from specific gravity indicator controller 28. In another embodiment the reaction vessel comprises a fluid receiving means for the reactants the lower portion of which is provided with apertures and extends into a reaction column. The column is composed of cylindrical sections and plates each having apertures obturate the column in spaced-apart relationship, and packing is disposed between the plates. An alternative reaction chamber comprises a reaction vessel with a centrally disposed perforated tube, and plates obturate the passage in the tube at intervals. Baffles close the passage between the tube and the inner wall of the reaction vessel, and one of each of the baffles is located intermediate the locations of two successive plates in the tube. The reaction vessel 1<SP>11</SP>, Fig. 3, is connected to the cooling tower 6<SP>1</SP> by a distributer 82 which has apertures 84. A de-entrainment means 86 is interposed between the distributer and a vent 85.
