Title: Improvements in and relating to generators of ultra short electromagnetic waves
IPC: H01J25/72
Filed: 1947-06-10
Abstract: 666,681. Electric discharge tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 10, 1947 [Aug. 30, 1946], No. 15220/47. Class 39 (i). A high-frequency current generator using secondary emission and a space resonance cavity, the oscillations taking place in said cavity producing several maxima of the electric field, is characterized in that the cavity is constituted by a box of conducting material in which secondary emission electrodes are mounted in pairs opposite each other, the electrodes being connected to the negative pole of a source of continuous voltage, the positive pole of which is connected to the box. In the construction shown in Fig. 1 a resonant cavity box Q of copper or of other metal or glass covered on the inner side with a layer of a good conductor and preferably of non-magnetic material, has openings O1 O<SP>1</SP>1, 02, 012 which may be latticed to allow the passage of electrons from the secondarily emissive circular plate electrodes a and b to a<SP>1</SP> and b<SP>1</SP>, and vice versa. The openings O<SP>1</SP> and O<SP>1</SP>1 and 02 and 012 are situated at distances from the ends of the box Q of a quarter of its length. An electromagnet producing a field parallel to the lines joining the centres of a and a<SP>1</SP> and of band b<SP>1</SP> or other means is used for focusing the electrons. A continuous voltage Vo is applied between the box Q and the electrodes a, a<SP>1</SP>, b, b<SP>1</SP>. The emitting electrodes constitute the bottoms of cylindrical condensers P, the plates p of which are connected to the box Q. The electrodes are supported by dome-shaped members R. Four or any number of electrode systems may be used and the box Q and electrodes may be of any shape. The emitting surfaces may be incorporated in the walls of the box or may be deposited thereon. The electrodes may be made of any material which has a coefficient of secondary emission much greater than unity for the electronic speeds that are used, such as alloys composed of light metals with the addition of a small quantity of iron and a metalloid as described in Specification 488,688 and French Specification 845,087. The box Q may be provided with hollow re-entrant parts, as shown in Fig. 6, in order that the time of passage of the electrons can be controlled. In the construction shown in Fig. 7 two incandescent starting electrodes I1, I2 which may comprise small balls covered with emitting oxides and heated by filaments f1, f2 are used. In order to increase the stability of operation thin conducting wires such as mn, Fig. 7, joining the centres of the faces of the box are used or the faces of the box are of the form shown in Fig. 8. Energy is extracted by a wire loop. Specification 625,901 also is referred to. The Specification as open to inspection under Sect. 91 states that the cavity resonator need not itself constitute a vacuum enclosure, the electrode systems being mounted in separate vacuum enclosures. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to yarn testing equipment
Inventor: BAMFORD HERBERT
IPC: G01N33/36
Filed: 1953-06-03
Abstract: 745,451. Cathode-ray oscilloscopes. T.M.M. (RESEARCH), Ltd. Aug. 18, 1954 [June 3, 1953], No. 15309/53. Class 37. [Also in Groups IX and XL (c)] A length of textile yarn is examined to detect periodic variations in its thickness by intensity modulating the rectangular raster of a cathode-ray oscilloscope with an electrical signal whose amplitude varies in time according to variations along the yarn of its thickness, said signal being first recorded on a magnetic tape and then subsequently reproduced and applied to the oscilloscope, so that the horizontal lines of the display raster correspond to successive equal-length portions of the yarn and the display corresponds to a two-dimensional arrangement of the yarn in which said successive portions are laid side-by-side so that any periodic variation in thickness which would give rise to an undesirable pattern effect when the yarn is woven into cloth will be visible as a pattern on the display. When a saw-tooth line time-base is employed the display corresponds to an arrangement of the yarn in which the successive portions are laid down in the same direction but when a triangular wave line timebase is employed the display corresponds to an arrangement in which the yarn is laid down in a zig-zag fashion. As shown in Fig. 1, a suitable length, e.g. 1000 yards, of yarn 1 is drawn by rollers 2 through a capacitor 3 connected to a circuit 4 giving an electrical output proportional to the thickness of the yarn, said output being recorded at 5 on one track of a twin-track magnetic tape which is driven synchronously with the rollers 2. The ends of the tape are then joined to form an endless loop which is passed continuously, e.g. sixteen times/sec., through a play-back device. 6, the yarn record track being passed through a pick-up head 7 whose output is applied to modulate the intensity of the beam of a cathode-ray oscilloscope which is scanned in a rectangular raster by line and frame time bases 11 and 12. The other track travels past a permanent magnet 9 and pick-up head 10 which emits a synchronizing pulse which is applied to timebases 11 and 12 when the join in the tape passes through pick-up 10 such that a new frame is started at each repetition of the magnetic record. The number of lines in the display can be varied to give the effect of different cloth widths by varying the speed of the timebases 11 and 12 or by varying the speed of the tape through the play-back device 6. In a modification, Fig. 2 (not shown), the tape is run through the play-back device once only at a slow speed, the output from pick-up 7 being recorded on a cathode-ray storage tube whose recording beam is scanned by low velocity timebases synchronized with the output from pickup 10 and the signal so recorded is reproduced repitatively on the display tube at a higher speed, the reading beam of the storage tube and the modulated beam of the display tube being scanned synchronously by high-speed time. bases.

Title: A process for the catalytic polymerisation of ethylene and catalyst compositions therefor
Inventor: ARLMAN EVERT JOHANNES
IPC: C08F10/00
Filed: 1960-05-02
Abstract: A process for preparing a pre-catalyst which can be converted by heating to a catalyst for use in the polymerization of ethylene comprises mixing (a) one or more dihalides of titanium with (b) one or more azo compounds which may be non-polar and more particularly may be such that those of its carbon atoms which are directly bound to a nitrogen atom are also bound to at least one hydrogen atom.  The preferred components are titanium dichloride and 4,41-azoheptane but titanium dibromide, azo-omega-toluene, azo-octane and azo-ethane are also specified. The relative molar proportion of (a) to (b) may be between 1:1 and 1000:1.  The pre-catalyst may be made by suspending or immersing (a) in a solution of (b) in a volatile inert solvent which is subsequently removed by evaporation or, alternatively, in the case of a volatile azo compound such as azo-ethane, by contacting (a) with the vapour of (b) at 80 DEG -200 DEG  C.  An example of the use of the catalyst derived from the pre-catalyst is given (see also Group IV(a)).  The Provisional Specification describes, in addition, the polymerization of olefins which may be ethylene, propylene or butylene and of dienes which may be butadiene or isoprene; also, the pre-catalyst comprises one or more azo compounds together with one or more solid halides of transition metals which may be ZrCl2, VCl2, VCl3, CrCl2, MnCl2, FeCl2, CoCl2, NiCl2, CuCl, WCl3 and MoCl3 and the corresponding bromides.ALSO:Ethylene is polymerized by contacting it at an elevated temperature, preferably 80 DEG -200 DEG C., with a catalyst obtained by heating a precatalyst prepared by mixing one or more dihalides of titanium with one or more azo compounds (see Group III).  The polymerization may take place in the absence of liquid diluents or solvents, the catalyst being prepared from pre-catalyst particles in an upward stream of a gas comprising ethylene.  The pressure of the ethylene may range from subatmospheric to 5-200 atmospheres. Alternatively the polymerization may take place in the presence of a diluent such as iso-octane, cyclohexane or toluene.  An example is given in which the purified polyethylene has a melting point of 124 DEG C. and an intrinsic viscosity of more than 5.  In the Provisional Specification propylene, butylene, butadiene and isoprene are also polymerized.

Title: Heat pumps
IPC: F25B30/00
Filed: 1962-04-19
Abstract: 942,636. Refrigerating; heat pumps. B. N. HOFFSTROM. April 19, 1962 [May 3, 1961], No. 15336/62. Heading F4H. An air cycle heat pump comprises a cylindrical rotor 32 mounted within a cylindrical casing 20, the rotor having axial holes 62 near its periphery communicating at an air inlet end of the rotor with radial passages formed by vanes 58 located between a wall 50 and a hollow hub 30 of the rotor and at an air outlet end with radial passages formed by vanes 60 located between a wall 52 and a hollow hub 40 of the rotor. The vanes 58 and 60 are milled from the hubs 30 and 40 and cemented to the rotor walls 50 and 52, and the rotor is driven by a motor 22 through a planet step-up gear system 82. The holes 62 may be replaced by milled axial slots in the rotor over which a sleeve is shrunk. As shown the heat pump is arranged to cause a flow of cold air through a domestic refrigerator. In operation the vanes 58 draw ambient air through the hollow hub 30 and cause it to flow outwardly to the holes 62 at the same time compressing and consequently heating it. In flowing along the axial holes 62 the air gives up heat to a stream of cold air flowing from the refrigerator through a channel 102 between the rotor 32 and the casing 20, and dust particles are deposited by centrifugal forces in the holes 62. The air is decompressed and consequently cooled as it passes inwardly over the vanes 60 and any condensate produced is thrown by centrifugal forces on to the inner wall of the hub 40 which is slightly tapered to allow the condensate to run into the rotor and thence through bleed openings 106. The cold air stream from the hub 40 passes over a set of stationary radial diffuser vanes 64 and thence through a duct 94 to the refrigerator, the return air stream from the refrigerator passing through a duct 96 and slots 100 in the casing 20 to the channel 102 which it leaves via slots 104 in the casing. The diffuser vanes are milled from an annular wall member 66 and cemented to another wall member 68. The heat pump may be used as a space heater by conducting the warm air from the slots 104 to the space, in which case the rotor 32 may be provided with vanes near the slots 104 to give an increased flow of air through the channel 102 and the ducts 94 and 96 communicate with the outside ambient air. With a suitable conduit arrangement the heat pump may be used for simultaneous heating and cooling.
