Patent GB-984739-A (GB)
Title: Improvements in or relating to the treatment of water
IPC: C02F5/00
Filed: 1961-08-24
Abstract: A process for the removal of carbon dioxide from an aqueous liquid containing carbon dioxide, comprising contacting the liquid with a refining agent comprising sintered, calcined dolomite in finely sub-divided form which has been stabilized with a silica-containing compound to combine most of the calcium oxide in the form of dicalcium and tricalcium silicate or both, whilst leaving the magnesium oxide substantially unchanged.  Suitable silica containing compounds are silicic acid, quartz sand, serpentine, talcum or other magnesia silicates, magnesium lime silicates or lime silicates.  The efficacy of the above material is improved if it is made porous, e.g. with aluminium powder, magnesium powder, calcium carbide or with foaming agents, mixed with water to form a paste and set hydraulically.

Abstract: 1322425 Scanning subscribers' lines for calling conditions INTERNATIONAL STANDARD ELECTRIC CORP 1 July 1971 [8 July 1970] 30891/71 Heading H4K A scanner looks at subscribers' lines serially and group by group and records line states in a buffer store, a dummy position at the end of the scan of each group being used to transfer to a call processor the parallel scan results accumulated for the group, the occurence of an off-hook scan condition causing the immediate sending to the call processor of the associated line identity. In order to distinguish originating off-hook conditions from the off-hook conditions exhibited by lines parked on junctor circuits, a lastlook comparison may be made with the result of the preceding scan as provided by and modified by the processor. By that means immediate applications to the processor may be confined to to the originating off-hook states. The current scan states accumulated for each group may be buffered before being compared with the lastlook results.

Title: Improvements in or relating to electric fluid heating apparatus
IPC: F24H9/20
Filed: 1931-11-09
Abstract: 378,716. Electric fluid-heating apparatus. CARLETON, R. A., 9115, Ridge Boulevard, Brooklyn, New York, U.S.A. Nov. 9, 1931, No. 30965. Convention date, July 31. [Class 39 (iii ).] A fluid heating apparatus comprises one or more chambers having narrowly spaced walls 23, 24 of insulating material, a number of thin metallic strips 22 of high resistance narrowly spaced apart and supported in an edgewise position, and held by split pins 26 between the walls 23, 24 so as to provide conduits 25 through which the fluid passes in direct contact with the strips, which are heated by passage of an electric current. Oil or other fluid so heated may be circulated through heat utilizing means such as jacketed kettles, or pipe coils. The heating means is contained in a shell 10, and enclosed in insulating material 18, and a fluid such as oil is supplied through a pipe 20, and, after being heated by contact with the strip 22, flows to an outlet 21, which is fitted witn a thermostat bulb 45 the control wires 46 from which vary the amount of current supplied to the heating elements. An automatic switch 47 in the inlet pipe 20 is provided to ensure that the current is only supplied to the heating elements when oil is flowing through the heater. When used for heating oil for circulation through the jacket of a kettle 51, Fig. 8, the outlet pipe 21 leads through a pipe 52 to the jacket 50, the return pipe 55 of which leads to a pump 56, and pipe 57 to the heater. A byepass 60, and expansion tank 62 are provided, excess of oil returning to circulation through a pipe 64. A branch 67 from the main electricity supply 66 operates through a switch 69 a motor 68 which drives the pump 56. Each of the three wires of the main 66 are connected to one end of each of the three heater units, and the other ends of the units are each connected to one of the poles of a magnetic switch 70 so that the three units form a # connection across the main. Another switch 71 connects all the wires from the heater units leading to the switch 70, and causes a reduced amount of current to pass through the circuit. Hand controlled, and magnetic controlled switches 72, 73 prevent current from reaching the heater units. The magnetic control is by wires 74, which lead to the control switch 47 operated by the pressure in the inlet pipe 20, and when oil is flowing, connection is made to wires 75 one of which is connected to each of the switches 70, 71, 73 and the other to the control switch 44 which in turn is connected by wires 46 to the magnetic switches. As the temperature rises, switch 70 is first opened, and finally switch 73 is opened cutting off the current. When used for heating the liquid in a tank 80, Fig. 9, pipes 52, 82 serve as flow and return pipes to the heater. The current is controlled by a thermostat 84, and also by a switch 85 which is operated when.the level of the liquid in the tank falls below a predetermined level. In a further modification the heater mav be located in a pressure chamber containing the liquid to be heated.

Title: New phosphorus nitrilo compounds
Inventor: IRVING ROGER JOHN
IPC: C07F9/6581
Filed: 1959-09-14
Abstract: The invention comprises compounds comprising PnNnX2n-m units linked together by other units of structure: <FORM:0921034/IV(a)/1> in which the constituents designated by X are halogen atoms or R, OR, NHR or NR1R2 radicals where R, R1 and R2 are hydrocarbon or fluorinated hydrocarbon groups e.g. fluoromethyl or fluorophenyl, and Y is a hydrocarbon or fluorinated hydrocarbon group, attached to phosphorus atoms of the said PnNnX2n-m units, n being at least 3, and in each PnNnX2n-m unit m being the number of <FORM:0921034/IV(a)/2> links to which the said unit is attached.  The constituents X which are not halogen atoms may all be different or any two or more of them may be identical.  At least one X may be an aryl amide group, e.g. a para-toluidide group.  The halogen is preferably chlorine.  Y may conveniently be an alkyl, e.g. CH3, C2H5, C3H7 or aryl group e.g. C6H5 or C6H4CH3 and n is conveniently 3 and is preferably not greater than 4.  The compounds may be obtained by reacting, preferably by heating, a phosphonic acid of formula: Y-P(O)(OH)2 with a phosphorus nitrilo compound of formula PnNnX2n where n is at least 3, at least one of the constituents designated by X is a halogen atom and any of the said constituents which are not halogen atoms are R, OR, NHR or NR1R2 radicals where Y, R, R1 and R2 are as defined above whereby the two reactants condense together by loss of hydrogen halide molecules. If only one of the constituents X is a halogen atom only two phosphonitrile units will be linked together and a dimer formed. When higher polymers are required more than one of the constituents X must be halogen atoms and it is preferred that the compound PnNnX2n contain only two halogen atoms otherwise branched chain compounds will be produced.  The two halogen atoms may be attached to the same or different phosphorus atoms.  The reaction is conveniently effected in solution and an inert solvent may be used, e.g. an aliphatic alcohol containing up to six carbon atoms.  Suitable reaction temperatures are between 70 DEG  and 100 DEG C.  A typical product is one having the structure:- <FORM:0921034/IV(a)/3> wherein X is the p-toluidine radical.  In an example the compound P3N3(p-CH3C6H4NH)4Cl2 and methyl phosphonic acid are refluxed in ethanol to yield a product containing an average of 3.5 phosphonitrile units.

Abstract: 774,677. Vapour burners. FRY, D. J. Dec. 9, 1953 [Dec. 2, 1952], No. 31216/52. Class 75(1) A vapour burner has a vaporizing section formed of one or more tube turns in heat conducting connection with the outer surface of a flame screen surrounding the flame and the burner nozzle is secured against movement of its longitudinal axes relative to the vaporization section. The flame screen formed as a tube 8 is attached to the ends of the arms of a U shaped member 14 secured to the fuel nozzle 12 by a nut 13. The liquid fuel contained in a tank 1 is kept under pressure by air pumped through a non-return valve 3 and is fed through a pipe 5 below the flame path to the forward end of the coils 9, where is it vaporized, and then through a tube 10 at the rear end of coils 9 and above the flame path to the nozzle 12. The vaporizing section is surrounded by a cowling 16 provided at its rear end with primary air openings and with a longitudinal slit above the pipe 5. A starting through 17 containing fine wire gauze or asbestos is mounted below the slit in the cowling 16. Fig. 4 shows the trough 17 as formed by the lower portion of a cylindrical casing 23 provided with primary air apertures at its rear end and eccentrically mounted with respect to the flame tube 8. An annular flame baffle 15 is welded to the inner periphery of the tube 8 and a stand 20 to the outer periphery thereof.
