Title: Manufacture of organic compounds containing halogen and phosphorus
IPC: C07F9/40
Filed: 1952-09-18
Abstract: The invention comprises compounds of the general formula <FORM:0744360/IV(a)/1> in which R1 represents an alkyl residue, which residue may contain substituents, R2 represents an aryl residue, which may contain substituents, X and Y each represent -O- or =N-Alkyl, Z represents oxygen, R4 represents hydrogen, halogen or halogen-alkyl, R5 represents hydrogen, an alkoxy group, a substituted or unsubstituted alkyl or phenyl group or a dialkylamino group and Hal represents a halogen atom.  Such compounds are obtained by reacting a compound of the general formula <FORM:0744360/IV(a)/2> in which R3 has the same meaning as R1 or R2 with a polyhalogeno-compound which contains in the a -position to a -CO- group more than one halogen atom and corresponds to the formula <FORM:0744360/IV(a)/3> a compound Hal-R3 being split off during the reaction. Aliphatic radicals which R1 and R3 may represent include straight and branched saturated and unsaturated radicals such as methyl, ethyl, propyl, isopropyl, butyl, hexyl, 2-ethyl-butyl, octyl, 2-butyl octyl, lauryl, octadecyl, allyl and 2-chloroethyl groups, and also radicals containing thiocyanic acid, cyano or ester groups. Aromatic radicals which R2 and R3 may represent may be mono- or polynuclear and include 2- or 4-chlorophenyl, 2:4-dichlorophenyl, 4-methoxyphenyl, 4-nitrophenyl, naphthyl and 4-diphenyl groups.  As polyhalogeno-compounds of the above formula are specified aldehydes such as dichloracetaldehyde, butylchloral, bromal and chloral, ketones such as polyhalogen-methyl ketones, e.g. 1 : 1-dichloracetone, 1 : 1 : 3- or 1 : 1 : 1-trichloracetone, 1 : 1 : 3 : 3 - or 1 : 1 : 1 : 3 - tetrachloracetone, penta- or hexa-chloracetone, o -trichloroacetophenone, 4 - chloro - o  - trichloracetophenone, 4 - methyl - o  - trichloracetophenone, esters in which R5 represents an alkoxy group such as esters of halogenated acetic acid, especially of trichloracetic acid, and amides in which R5 represents the residue of a primary or secondary amine, e.g. trichloracetic acid dimethylamide.  The reaction may be effected in a solvent.  The products have animal and vegetable pest-combating properties.  Examples describe the reaction of (1) p-chlorophenyl diethyl phosphite and chloral. Instead of chloral, 1 : 1 : 3 : 3 - tetrachloracetone can be used; (2) 2 : 4-dichlorophenyl diethyl phosphite and chloral.  Instead of chloral butyl chloral or trichloracetic acid ethyl ester can be used; (3) chloral and diethyl (methyl-phenyl amido) phosphite (C6H5N(CH3).P(OC2H5)2); (4) pentachlorophenyl diethyl phosphite and chloral.

Title: Separation of uranium, plutonium and fission products
IPC: G21C19/46
Filed: 1949-09-15
Abstract: 840,105. Separation of uranium and plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 15, 1949 [Sept. 20, 1948], No. 23812/49. Drawings to Specification. Class 39(4). Uranium and plutonium are recovered from neutron-irradiated uranium by extracting an aqueous nitric acid solution of the irradiated uranium with an organic solvent of low solubility in the aqueous solution. The uranium and plutonium pass into the solvent phase leaving fission products in the aqueous phase. The initial solution may be 2N-4N in nitric acid and the organic solvent may be acidified with nitric acid to 1À8N. The extract containing uranium and plutonium may be neutralised with a base, treated with a reducing agent to reduce the plutonium to the tervalent state and extracted with an aqueous nitrate solution, which removes the plutonium, leaving the uranium in the organic phase. Suitable organic solvents are dibutoxy-diethyl ether, ethylene glycol dibutyl ether, and methyl isobutyl ketone. The aqueous nitrate solution may contain ammonium, aluminium, calcium, or zinc nitrate. Reducing agents specified are hydroxylamine, hydroxylamine nitrate and hydrochloride, hydroquinone, hydrazine and salts thereof, ferrous sulphamate, sulphur dioxide, and a mixture of ferrous sulphate and hydrazine. Bases used for neutralisation are ammonium hydroxide, aluminium hydroxide, calcium hydroxide, and zinc oxide and hydroxide. The extraction may be carried out continuously using packed extraction columns and three processes are described with reference to flow diagrams. The organic solution of uranium from which plutonium has been separated is contacted with water or dilute nitric acid ; uranium passes into the aqueous layer and the organic layer is treated with charcoal and distilled to recover the solvent. In a modification of the process, uranium and plutonium are both removed from the solvent extract by washing with water, the organic solvent is recirculated and the aqueous solution neutralised, reduced, and contacted with solvent and salt solution to yield an organic phase containing uranium and an aqueous phase containing plutonium. Matter claimed in Specification 805,000 is disclaimed.

Title: Improvements relating to electric selective systems

Filed: 1934-08-18
Abstract: 437,766. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, London. Aug. 18, 1934, No. 23839. [Class 40 (iv)] Different classes of subscribers' lines are distinguished by the speed of operation of their cut-off relays, and the class of a called line is recognized in the final selector by whether or not a relay connected up upon energization of the test relay has time to operate before the cut-off relay pulls up. When the marking switch MS has been set by the incoming digits, relay C (not shown), falls back and connects up latch magnet L in series with U(ii) to advance the final selector to the marked line, relay TA being short-circuited. Test relay T, which may be a high-speed relay of the kind described in Specification 405,436, [Group XXXVII], energizes in series with cut-off relay CO, opening the circuit of L and U(ii) and removing the short-circuit from TA, which energizes in series with L. Relay CO upon operating removes the shunt resistance CR, thus increasing the impedance of the test circuit sufficiently to cause T to relapse momentarily. If this occurs before TA has operated, a circuit is closed over back contact ta1 for relay V, which locks, while if TA has already operated, V remains inoperative. A relay similar to V may be connected to front contact ta1 to respond in the latter case. While relay T is back, the line is guarded by virtue of the fact that the increase of impedance which causes its release also prevents the operation of a second relay T. The arrangement may be used to determine whether or not ringing is to take place.

Abstract: 1,066,972. Heating steam boilers by hot liquids. FOSTER WHEELER Ltd. June 19, 1964 [June 19, 1963; Jan. 16, 1964], Nos. 24423/63 and 2085/64. Heading F4A. In a once-through steam boiler heated by a liquefied metal, e.g; sodium, coolant of a nuclear reactor and comprising a vertical, cylindrical pressure vessel 10 containing an' open-topped vessel 12 with a sodium inlet 40 and outlet 44, the vessel 12 contains a number of vertical ducts 25 extending between plates 15, 22 and passing through an intermediate plate 14. Sodium leakage occurs where the ducts pass through plates 14, 22 to establish a small flow through space 46, the major flow being through the ducts, the sodium entering at 42 and leaving through their open lower ends. The vessel 10 is pressurized by an inert gas. Within each duct is housed a boiler unit consisting of a cluster of vertical tubes extending between headers 28, 30, each cluster comprising a central downcomer tube which connects a feedwater inlet 36 directly with the lower header 30 and a number of riser tubes which discharge steam into the upper header 28 whence it leaves the boiler through an outlet 38. Similar units may be used as economizers, superheaters and reheaters. With this arrangement the consequences of a tube failure are localized in the particular duct and tube replacement is facilitated, the faulty unit being lifted into a sealed flask, after sealing the inner container by plugs 18, removing the cover 47 and cutting the connections 36, 38. In a modification, Fig. 4 (not shown) the boiler unit connections 36, 38 are brought down through an axial duct and leave the vessel 10 through its bottom wall.
