Title: Improvements in or relating to magnetrons
IPC: H01J25/56
Filed: 1946-09-16
Abstract: 616,866. Magnetrons. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Sept. 16, 1946, No. 27781. Convention date, Sept. 15, 1945. Addition to 574,551. [Class 39 (i)] In a magnetron according to the parent Specification, in which the anode comprises interdigitated members forming the inner wall of an annular chamber constituting a cavity resonator, parts of the cathode in which high-frequency currents are induced and which do not belong to the cavity resonator-oscillation system, are complemented to form a low radiation cathode - oscillation system tuned to minimize high-frequency losses in the magnetron. The cathode heater leads may comprise a Lecher line closed by a condenser. This condenser may comprise a valve acting as a variable condenser for modulating the magnetron oscillations. The cathode heating current is supplied over side plates supporting the cathode. Where the side plates and cathode are electrically separate from one another, each may be tuned by a separate Lecher line. In another arrangement a quarter-wavelength long concentric line acting as a choke to the high-frequency currents is inserted in one of the leads and may be either inside or outside the magnetron; it may be formed as a boring in one of the magnet polepieces. The output energy is abstracted from the magnetron by a loop inside the annular cavity resonator, or the high-frequency currents flowing in the cathode may provide the output energy, which is abstracted at 21 from the Lecher line constituting the cathode leads 3, Fig. 4. The Lecher line is tuned by the impedance 18 which may be a cavity resonator. The spiral cathode 1 has a low-loss conductor 19 connected in parallel with it through a condenser 20 to reduce' high-frequency losses in the circuit.

Filed: 1924-11-21
Abstract: 247,661. ]3randwood, J., Stocker, A., and Twyver Works, Ltd. Nov. 21, 1924. No Patent granted (Sealing fee not paid). Hank type.-In apparatus for treating hanks with liquids. the hank-supporting rollers 12 are fed in successive steps from one end of a frame 9 to the other beneath treating tanks 10 by placing their ends on travelling belts 28 between stops 32 on rails 31, adapted to be automatically lifted at regular intervals with respect to the frame 9, the rollers 12 being rotated by the belts 28 until the stops 32 are lifted, when they are moved forward a step by the belts so as to be positioned between a new pair of stops 32 when the latter descend. The belts are supported on anti-friction bowls 29 on L-section rails 30 bolted to the frame 9 and pass over end pulleys 14, 16. the pulleys 14 being mounted on a suitably driven shaft 22. Each pulley 14 is provided with a projection 37 adapted to coact with one end of a pivoted lever 35, the other end of which is connected by a rod 33 with the rail 31, so as to lift the rail and its stops 32 once during each revolution of the pulley 14. Means may be provided to prevent a roller being rotated by the belts at a certain point or points during its traverse through the frame. As shown in Fig. 6, this is effected by forming a recess 40 in the upper edge of a plate, 30<a> attached to the inside of one of the rails 30 and arranging the stops 32 at this point more apart than in other cases so that the roller 12 places itself obliquely as shown. Glass rods 41 supported in brackets 42 on the ends of the frame 9 keep the hanks suspended from a single roller apart as the roller traverses the apparatus.

Title: Sulphonation of alkylated aromatic hydrocarbons
Inventor: BROOKS RICHARD JAMES
IPC: C07C303/06
Filed: 1958-08-29
Abstract: A continuous process for sulphonating an alkylated aromatic hydrocarbon which is relatively insoluble as defined below in 75 to 86% sulphuric acid comprises continuously reacting an alkylated aromatic hydrocarbon with a sulphonating agent as defined below by simultaneously and intimately mixing the hydrocarbon with a stoichiometric excess of a sulphonating agent in the presence of recirculated previously formed sulphonation reaction mixture, the rate at which this previously formed reaction mixture is recirculated being at least 15 times the rate at which the hydrocarbon and sulphonating agent are introduced into the reaction mixture, splitting the thus produced mixture into a portion to be recirculated and a portion to be digested, recirculating the portion to be recirculated, digesting the portion to be digested for a period of time sufficient to assure substantially complete sulphonation of the hydrocarbon, adding water to the reaction mixture comprising substantially completely sulphonated hydrocarbon and excess sulphonating agent and forming a rapidly settling emulsion in which dilute excess sulphonating agent is the continuous phase and sulphonated hydrocarbon is the discontinuous phase and recovering the sulphonated hydrocarbon phase.  The sulphonic acid may be neutralized with a base, e.g. sodium hydroxide solution.  A flow diagram (not shown) is furnished.  The examples relate to the sulphonation of an alkyl benzene having 12-15 carbon atoms and pentadecyl benzene with fuming sulphuric acid, centrifugal pumps being employed to effect mixing of the reactants.  The expression "relatively insoluble" as applied to the sulphonated alkylated aromatic hydrocarbon means it is sufficiently insoluble in 75-85% sulphuric acid to separate rapidly as an upper phase from excess aqueous sulphonating agent as a lower phase.  The sulphonating agent employed is concentrated sulphuric acid or fuming sulphuric of up to 30% strength.

Abstract: 750,815. Purifying radio-isotopes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 12, 1953 [Oct. 15, 1952], No. 27979/53. Class 39 (4). To produce a radio-active preparation from the products of a nuclear reaction, the ions of radio-active metal are separated from the ions of the metal subjected to the reaction by adding to an aqueous solution containing the metals a metal intermediate between the metals of the reaction in the electromotive force series of elements, and then using either the added metal with the deposit produced thereon or the solution liberated therefrom to make the preparation. Mn<SP>52</SP> produced by bombarding Cr with deuterons is dissolved in HCl with the Cr which deposits on powdered Zn added to the solution. The Mn<SP>52</SP> is then extracted from the filtrate with isopropyl ether after depositing it with ferrichloride in the presence of NaOH and H 2 O 2 , the extraction with ether being repeated to remove the remaining iron ions. A purer Mn preparation is obtained from a HCl solution of the iron hydroxide/manganese precipitate formed by using ammonia and ammonium acetate and shaking out with a mixture of benzoyl acetone in toluene. Similarly, preparations containing CO<SP>56</SP>, CO<SP>57</SP>, CO<SP>58</SP>, Mn<SP>54</SP> are obtained after bombarding Fe with deuterons to produce these isotopes, using powdered Zn to deposit the Co from solutions containing Mn, Co, after removing the Fe with ether. Also preparations containing Cd<SP>109</SP> (ex d + Ag reaction) are produced after depositing the Ag on Sn filings.

Abstract: 1390647 Curing extruded cable covering BRITISH INSULATED CALLENDER'S CABLES Ltd 18 June 1973 [19 June 1972] 28681/72 Addition to 1201528 Heading B5A [Also in Division C3] In the parent Specification, an insulating covering extruded around an advancing core is cured by heated fluid at super-atmospheric pressure in passage through a chamber hermetically sealed to the extrusion die, and a predetermined fluid pressure differential is maintained between the chamber and a core tube within which the core passes through the extrusion die, to prevent the extruded covering being forced back along the tube. In the present application the chamber additionally effects radiant heating of the covering, and this may avoid condensation of the fluid medium, e.g. steam, on the covering which would inhibit escape of the cross-linking agent from the covering and cause bubble formation. The covering may comprise natural neoprene, butyl, silicone, or styrene butadiene rubber, or olefine polymers containing cross-linking agents. The fluid medium in the chamber may comprise steam, or carbon dioxide, but in the described embodiment comprises nitrogen. The core may comprise a previously covered or uncovered wire, or wire group. In the described embodiment, the polyethylene is applied to a preheated sector shaped base aluminium conductor which is drawn, from the die 11, through the chamber 5 which is downwardly inclined and through which nitrogen is circulated in the direction opposite to core movement at its upstream end, and which contains cooling water at its downstream end. A further cooling water means is provided downstream of the chamber. The chamber 5 is thermally insulated at 20 and heated by a plurality of axially spaced heating devices, each comprising a plurality of turns of mineral insulated heating cable and being independently automatically controlled from a thermocouple (19), Fig. 4 (not shown). The medium may be heated prior to introduction to the chamber 5. Where the medium is steam, it has a saturation temperature that does not exceed that at which the covering is cured. The heating device may alternatively be outside of, or within the chamber 5. The pressure difference across covering 8 is maintained constant by automatic control of the pressure of nitrogen in the chamber 5 and/or in the core tube 14, and/or by controlled leakage of nitrogen from the tube 14.

Abstract: 736,024. Washing-machines. HOOVER, Ltd. Nov. 11, 1953 [Nov. 14, 1952], No. 28794/52. Class 138 (2). A washing-machine having a pump for emptying the washing liquid container through a delivery pipe 20 is provided with means for introducing disinfectant or deodorant material into any residue of liquid not delivered from the pipe 20. In the example shown the pipe 20 is connected to a chamber 24 containing a block 25 of deodorant which is progressively softened by liquid flowing through a central bore 35 in the block. When the container is empty the pump is stopped and the residual liquid in the pipe 20 flows back into the pump and a sump below the container. The dissolved deodorant keeps this liquid hygienic. A bracket 26 for supporting one end of a wringer has a hollow elbow 28 the horizontal part 29 of which receives a flexible outlet hose (not shown). The bracket 26 has a screwed connection with the top 32 of the chamber 24, the chamber 24 and top 32 having a bayonet connection 33. In another example (not shown) the deodorant chamber is connected to the delivery pipe through a branch passage, and a venting valve allows air to leave the chamber so that liquid can enter it, but is closed by a float when the chamber is full of liquid. The valve opens again when liquid ceases to be delivered so that the liquid in the chamber can then flow back into the delivery pipe and pump. In this case the deodorant or disinfectant may be in the form of crystals. Specifications 612,737 and 701,977 are referred to.
