Filed: 1967-06-27
Abstract: 1166704 Preventing corrosion BROWN BOVERI & CO Ltd 27 June 1967 [29 June 1966] 29618/67 Headings CSG and G10A In a thermal power-plant wherein combustion gas gives up its heat to a steam circulating system via the heat exchange surface 3 of a boiler, sodium carbonate, in dust form is introduced with combustion air into the combustion space 1 of an oilfired boiler to combine with the SO 3  and NO 2  present forming water soluble sodium salts which are separated out from the combustion gas partly at a dust trap 4 and partly at a washing appliance 5 which comprises a circulating pump 6 and an atomizer 7. The sodium salts collected at the points B are passed in aqueous solution to an ionexchanger, in the ammonium form, where ammonium is exchanged for sodium. The resultant solution of ammonium sulphates and nitrates is further processed to form a commercial fertilizer. The ion-exchanger is then regenerated to the ammonium form, and sodium carbonate is recovered to be recirculated to the combustion space 1. Alternatively sodium bicarbonate may be formed and introduced into the space 1, or under certain conditions sodium hydroxide, formed in the recovery process, may be used. A cooling jacket 2 is provided to parts of the plant over which combustion gas passes to keep the wall temperature below the melting point of the sodium salts. The above process may be applied to an MDH steam power-plant Fig. 2 (not shown) wherein potassium compounds, which also serve as seed material, are additionally added to the combustion air.

Abstract: 1424589 Automatic voltage control  TOKYO SHIBAURA ELECTRIC CO Ltd 22 June 1973 [23 June 1972] 29841/73 Heading G3R A voltage regulator for a battery-charging vehicle alternator includes a switching transistor connected in series with the alternator field winding and controlled in dependence on the battery charging voltage. If the sensed voltage approaches zero, the transistor is turned off by connecting its base to earth.  As shown, battery 6 is charged over main rectifiers 4, and field winding 3 is energized by way of auxiliary rectifiers 7 and connected in series with a Darlington transistor pair 8, 9. A potentiometer 17, 18 senses the battery terminal voltage, and when a Zener diode 14 breaks down, a transistor 12 is turned on causing transistors 8, 9 to be switched off. A resistor 25 is also connected to voltage sensing lead 19, and if the sensed voltage falls to a low level due to disconnection or severing of the lead, a transistor 24 is turned off and a further transistor 22 becomes conductive and connects the base of transistor 9 to earth, so that the field winding 3 is de-energized. Resistor 25 may alternatively be connected to the mid-point of potentiometer 17, 18, Fig. 2, (not shown), and transistor 24 may be connected to the base of transistor 9 by way of resistor 23 and a diode, Fig. 3 (not shown). In a further embodiment, Fig. 4 (not shown), a second voltage sensing lead is connected between the output of the auxiliary rectifiers 7 and the Zener diode 14 so that the alternator voltage is limited if the charging lead from the rectifiers 4 to the battery is disconnected or severed.

Title: Improvements in or relating to incandescent cathode rectifiers
IPC: H01J17/04
Filed: 1927-11-08
Abstract: 280,550. Meyer, F., and Spanner, H. J. Nov. 15, 1926, [Convention date]. Addition to 276,303. Vacuum tubes.- In incandescent - cathode rectifiers with conductive shielding plates between the anodes as in the parent Specification, the plates are connected to the cathode through an auxiliary source of potential so that they are negative with respect to the cathode during the parts of the cycle when the corresponding anodes are negative. The plates may comprise grids wholly or partly surrounding the electrodes. At high voltages, the potential applied to the plates by the source deflects or neutralizes rapidly moving positive ions and prevents destruction of the electrodes. At low voltages, particularly with large currents, destruction of the electrodes due to heat produced by ionic currents is prevented. In a rectifier with shielding grids 7, 7<1>-, Fig. 1, around the anodes 4, 4<1>, the anodes are connected to one secondary 5 of the supply transformer, the cathode is heated by a second secondary 2 and the grids 7, 7<1> are connected to the ends of a third secondary 8, the centres of the secondaries 2, 8 being connected. Resistances 10, 10<1> reduce grid currents. The grids may comprise semicircular slotted plates or flat plates with punchedout, bent tongues. In a modification with a single shielding grid around the cathode between the anodes, this grid is made negative by a battery connected between it and the cathode. The cathode may be divided as in Specification 279,024.

Title: Heterocyclic pyrophosphate esters and the production thereof
IPC: D06M13/292
Filed: 1954-10-19
Abstract: The invention comprises heterocyclic pyrophosphate esters of the formula <FORM:0770419/IV(b)/1> wherein R, R1, R2, R3 and R4 each represent hydrogen or an alkyl group, and n is 0 or 1.  The pyrophosphate esters may be prepared by reacting a 2-halo-2-oxo-1,3,2-dioxaphospholane or dioxaphosphorinane <FORM:0770419/IV(b)/2> wherein Hal = chlorine or bromine, under substantially anhydrous conditions with the anhydrous alkali metal or ammonium salt of a saturated mono-, di- or tri-carboxylic acid, at a temperature between 50 DEG  and 200 DEG  C., preferably 50 DEG  and 100 DEG  C.  The phosphorus-containing reagent is preferably added slowly to a suspension of the salt in an inert solvent for the product.  The novel compounds may also be prepared by reacting the above halogeno compound with water in the presence of just enough of a base, preferably pyridine, to take up the hydrogen halide formed. In either preparation, the reaction mixture is washed with water and with aqueous alkali metal bicarbonate and the oily layer is stripped by distillation to a temperature of 100 DEG  C. under 2 mm. pressure to remove solvent and water.  Suitable salts for use in the first method are alkali metal and ammonium salts of fatty acids having one to 18 carbon atoms, di-salts of oxalic, glutaric, succinic, adipic, pimelic and sebacic acids and tri-salts of tricarballylic acid. According to examples, to a suspension of anhydrous sodium acetate in toluene at 100 DEG  C. is added the appropriate 2-chloro-2-oxo-1,3,2-dioxaphosphorinane or phospholane to give (1) 2,21-oxy-bis (2-oxo-4-propyl - 5 - ethyl - 1,3,2 - dioxaphosphorinane); (2) 2,21 - oxy - bis (2 - oxo - 4 - methyl - 1,3,2 - dioxaphospholane); (3) 2,21 - oxy - bis (2 - oxo - 5 - 5 - butyl - 5 - ethyl - 1,3,2 - dioxaphosphorinane); (4) 2,21 - oxy - bis (2 - oxo - 5,5 - diethyl - 1,3,2 - dioxaphosphorinane); (5) 2,21 - oxy - bis (2 - oxo - methyl - 1,3,2 - dioxaphosphorinane); (6) 2,21 - oxy - bis (2 - oxo - 4,6 - dimethyl - 1,3,2-dioxaphosphorinane).  In Example (7) sodium butyrate in toluene is used giving the same product as (1)); (8) the halo-oxo-dioxaphosphorinane is dissolved in benzene, water and pyridine are added thereto and the mixture is heated, giving the same product as (1).  The products may be useful as plasticisers, as dyeing assistants and in biological applications.

Abstract: 365,071. Actuating drum controllers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Oct. 9, 1930, No. 30244. Convention date, Oct. 9, 1929. [Class 38 (iii).] Checked by motor current.-The control drum of an electrically driven vehicle is driven by automatic ratchet mechanism, the electrical operation of which is controlled by a hand or foot-actuated lever, which also operates directly a mechanical control device for the ratchet gear. When a pedal p is depressed a controller d is moved step by step by selfa c t i n electromagnetically operated pawl-and-ratchet mechanism o, r, s, v, until the final position VII is reached, when the circuit of the electromagnet o is interrupted at the controller d. When the pedal is released it first interrupts the circuit of the electromagnet o at k, then its neb 1, Fig. 2, engages a member 2 to lift the pawl 7 from the ratchet wheel r, and finally the member 2 lifts a detent w so that a spring t returns the controller d to its original position. The controller d may be moved to any desired position by slightly lifting the pedal p when that position is reached. To prevent too rapid movement of the controller d, contacts m in the circuit of the electromagnet o are controlled by a coil g in the motor circuit. Alternatively the coil g may act on the core of the driving magnet o. The magnet o may be a rotary magnet, and the drive may be electropneumatic instead of electromagnetic.

In a system for recording a large number of variables digitally on magnetic tape, in particular variables relating to an aircraft in flight, 200 analogue variables are sub-multiplexed in groups, each less than 10, to 30 pulse duration converters (P.D.C.), each of which produces a pulse train of constant frequency but in which the width of the pulses represent the data, the P.D.C. outputs are multiplexed, in suitable groups, to three pulse code converters (P.C.C.) which digitize the duration significant pulses by counting high frequency clock-pulses for the duration of one of the duration significant pulses, and the count reached is recorded in parallel on magnetic tape. The three P.C.C's use different capacity counters, and therefore require different numbers of tracks. The six-bit coder operates at half the speed of the other two coders and its six bits are recorded as two groups of three bits on three tracks. Provision is also made for recording the time of day, intercom speech, and various other variables which are sensed by digital transducers.

Abstract: 310,496. Michelin et Cie. April 27, 1928, [Convention date]. Dynamometers.-The intensity of vibrations or shock to which a body, such as a vehicle, is subjected over a period is determined by measuring the change in state, either physical or chemical, of a body or bodies to which the vibrations, &c. are transmitted. In one example as shown in Fig. 1 a container A is provided with a thermometer B and is partly filled with mercury, glycerine or other liquid which is agitated by the vibrations to cause a rise in temperature, the change in temperature affording a measure of the mean value of the shocks. The container may be fitted with vertical and horizontal baffles and have an insulated covering. The bottom of the container may contain a viscous liquid or particles of solid material. In another example unmiscible liquids of different densities, reacting chemically, such as mercury and iodine dissolved in potassium iodide, or ortho chloro-phenol and ether, may be employed, the rise of temperature due to shock being measured by a thermometer. In another example, Fig. 5, solutions 7<1>, 8 capable of dissolving colouring matter are employed. These solutions may be sulpho-cyanide of cobalt and amyl alcohol. The solution 7<1> may be replaced by an absorbent body such as activated carbon and the liquid 8 be a solution of methylene blue. In another example the measurement of a gas liberated as the result of the chemical action of an acid on a metal compared with that given off under stationary conditions affords a measure of the vibrations. In another example, Fig. 8, the container A is provided with a chamber 13 for a liquid or solid in powdered form and with an aperture 14 through which the contents escape when subjected to vibration. The change in weight of the container A or chamber 13 is a measure of the vibrations.
