Patent GB-1289897-A (GB)
IPC: H01J49/02
Filed: 1970-06-09
Abstract: 1289897 Mass spectrometers UNITED KINGDOM ATOMIC ENERGY AUTHORITY 27 May 1971 [9 June 1970 26 Nov 1970] 28001/70 and 56397/70 Addition to 1171700 Heading H1D The apparatus of the parent Specification is modified in that the first apertured electrode 8, preceding the first retarding electrode 9 and at which secondary electrons are produced by ions repelled from said retarding electrode, instead of.being grounded, is provided with a connection whereby it is maintained at a potential which is high relative to that of the apertured input electrode 6 of the measuring apparatus and of opposite polarity to the potential applied to said first retarding electrode 9. The effect is firstly to increase the energy of repelled ions which strike electrode 8, thereby increasing the secondary electron coefficient, secondly, the emitted electrons strike the scintillator 10 with increased energy, thereby increasing the light output to the photo-cathode 12 of the photomultiplier tube located beyond window 11. A further electrode 7 may precede electrode 8 and may be held slightly, e.g. 200 v., negative thereto, thus providing an increased p.d. relative to electrode 9. Electrode 8 then serves also to suppress any secondary electrons produced by the incident beam 4 striking electrode 7. The slit in electrode 7 may include a grid to increase the uniformity of the field. A second retarding electrode may be provided as described in the parent Specification to determine the energy range of ions that may be detected. In a modification (Fig. 2, not shown), electrode 8 has a semi-cylindrical raised portion located to one side of and parallel to the slit in the electrode to provide a transverse field component which prevents positive ions being repelled by electrode 9 back through the slit. In this arrangement an earthed electrode may immediately follow electrode 6.

Abstract: 1316748 Crystallization apparatus IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Sept 1970 [27 Oct 1969] 52440/69 Heading B1G In a process for separating a crystallizable compound from a melt or solution containing it the liquid is fed into an elongate purification chamber through an inlet and the spent liquor removed from an outlet remote from the inlet. Within the chamber the liquid runs along and between closely adjacent confronting surfaces, one of which is heated and the other cooled, the crystals which separate on the cooled surface being mechanically impelled towards an outlet remote from both the above-mentioned inlet and outlet. The crystals are moved by means of a rotary movement between the cooled surface and a displacement means preventing an oblique surface to the crystals. In the embodiment shown in Fig. 1, an inner cylinder 1 is cooled by liquid flowing through it, and outer cylinder 2 is heated by liquid flowing between it and a heating jacket. The liquid containing the crystallizable compound is fed in via inlet 12, the spent liquor being removed via outlet 14 and the purified crystals via outlet 13. The crystals are moved towards outlet 13 by means of the relative motion of cylinder 1 and helical fins 3 on cylinder 2; this motion being achieved by rotation of cylinder 1.  In other embodiments the outer tube may be cooled, or the inner tube have fins, the inner tube may be conical or may be replaced by a flat rotatable disc.

For the method of making the foamed resin see C3 abridgment. Specified thermoplastic resins include polyolefins, especially high density polyethylene, and polyamides, especially nylon 6. Desirably, the proportion of cells that contain perforated cell walls is from 70 to 100 per cent and the number of holes in the majority of the perforated cell walls exceeds 50. Preferably the holes in the majority of the perforated cell walls take up from 10 to 60 per cent of the total surface area of the cell wall under consideration. The majority of these holes may be from I to 50 microns in width, and most of the cells may have a diameter within the range of from 0.005 to 0.01 inch. Desirably, the foamed themoplastic resin has a hardness of from 75 to 90 per cent, and the resilience of the resin is from 90 to 100 per cent. The pressure drop across the filtering element is suitably less than 10 cms. water gauge for a sample 15 mm. in length, at a flow rate of 1050 ccs. of air per min. The smoke filtering element may be made by extruding a rod of the foamed resin, the rod having a transverse cross-section substantially corresponding to that derived in the final elements, and cutting or otherwise dividing the rod into pieces the length of an individual filter element. Conveniently, an extruded rod of the resin of length 2 to 10 times that of an individual element and of transverse cross-section corresponding to that of an element may be extruded and cut into a number of cigarette smoke filtering elements.

Abstract: 1329893 Valves CONCENTRIC CONTROLS Ltd 19 April 1972 [20 April 1971] 10141/71 Addition to 1329243 Heading F2V The metering gas tap according to the parent is modified in that bleed port (17) and counterbore (18) in the earlier plug are replaced by an elongate port 47 co-operating with a supplementary port 46 in the body, the latter port receiving gas from inlet passage 12 via passages 40, 33, 34, 42 under the control of a screw 35 which is retracted from the end of passage 34 when town gas is used but which is advanced to restrict flow when natural gas is used. A sleeve 30 limiting retraction of screw 35 also acts to limit rotation of the plug by engaging a radial pin (23) in the spring-biased operating spindle (21) received in the plug at (19). Port 47 is wide enough to ensure that flow therethrough continues even in the fully-on position, and is located such that flow begins after 48 degrees of rotation, with the simmering range commencing at 55 degrees with town gas and 65 degrees with natural gas. Groove 48 starts to register with passage 12 after 82 degrees, and main port 17 in the plug starts to register with passage 12 after 110 degrees, total rotation being limited to 170 degrees. Pin (23) in the plug moves in slot 26 which defines an off-position at (27) and an intermediate simmer-position at (28). Passages 40, 42, 44 are each sealed at their outer ends by a ball forced into the respective passage.

Abstract: 1355372 Automatic control of arc discharge and position P G TOWLSON 1 May 1972 [3 May 1971] 12638/71 Heading G3R Electromagnetic radiation is produced by an arc discharge between two electrodes. The electrode separation is automatically adjusted in response to an arc characteristic to a value less than that at which a minimum occurs in the arc voltage/separation curve. In the arrangement shown, an arc is produced between an anode 31 and cathode 32. Radiation from the arc is transmitted by a mirror or lens system to a workpiece 54 to be heat-treated. The electrode separation is maintained at a value less than that of an arc lamp in order to produce a concentrated transferred arc with high infrared emission. The position of the anode tip 35 is stabilized by a system 37 including a lens 46 transmitting radiation to a pair of photo-transistors 49, 50 arranged in a bridge circuit, Fig. 4, (not shown). The bridge output operates a servomotor 38 to control the anode position. The cathode position, and thus the electrode separation, may be controlled by a similar arrangement, or the measured arc voltage may be compared with a reference voltage 43 in an error signal forming circuit 42. The error signal is used to operate a cathode servomotor 40 through a switch 45 which is set according to the polarity of the voltage/separation curve characteristic slope.
