Title: Substituted phosphoramide compounds and their conversion to substituted benzamide derivatives
IPC: C07C237/34
Filed: 1971-12-20
Abstract: 1353499 Preparing substituted benzamides; substituted phosphoramides SOC D'ETUDES SCIENTIFIQUES ET INDUSTRIELLES DE L'ILE-DE-FRANCE and TEIKOKU CHEMICAL INDUSTRY 20 Dec 1971 [21 Dec 1970] 59101/71 Headings C2C and C2P A substituted benzamide of the formula in which A is a C 1 -C 5  alkylene group, X is H or halogen, R 3  is H, OH or C 1 -C 5  alkoxy and R 1  and R 2  are each C 1 -C 5  alkyl, or salt thereof, is obtained by reacting a substituted benzoic acid of the formula: with a novel phosphoramide compound of the formula: or a salt thereof. The reaction is suitably effected by heating the reactants at 50-150‹ C. in an inert solvent and when the phosphoramide is used in the form of a salt, e.g. the hydrochloride, the product I is also obtained in the form of a salt. Examples are given for the production of substituted benzamides of Formula I in which (a) R 1  and R 2  are each ethyl, X is Cl and R 3  is OCH 3  and OH respectively, (b) R 1  and R 2  are each ethyl and R 3  and X are each H, the product being obtained directly as the hydrochloride by using the phosphoramide in the form of its trihydrochloride and (c) R 1  and R 2  are each ethyl, R 3  is methoxy and X is Br. When R 3  in the product I is OH the product can be converted to the corresponding compound in which R 3  is alkoxy and in one example 2 - methoxy - 4 - amino - 5 - chloro- (N,N-diethylaminoethyl) benzamide is obtained by treating the corresponding 2-hydroxy compound with dimethyl sulphate. Also, when X is H in the product the latter may be converted to the corresponding 5-chloro compound by treatment with a suitable chlorinating agent, e.g. phenyliodine dichloride, iodine trichloride or succinic imide chloride. The products have pharmacological activity. The novel phosphoramides of Formula III are obtained in the form of their trihydrochloride salts by reacting an appropriate N,N- dialkylene diamine, e.g. diethylethylene diamine, with phosphorus oxychloride and the resulting salt can be converted to the free base by adding an alkali to the trihydrochloride salt. 2 - Hydroxy - 4 - amino - 5 - chlorobenzoic acid is obtained by reacting p-aminosalicylic acid with an appropriate chlorinating agent, e.g. phenyl iodine dichloride, iodine trichloride, succinic imide chloride, or cyanuric chloride.

Patent GB-2011069-A (GB)
Title: Photoelectric leak detection
IPC: G01M3/38
Filed: 1978-11-24
Abstract: In apparatus to detect leaks in composite can ends (comprising metal and a sealing compound), can end 10 is held by clamp 12 and irradiated by stroboscopic lamp 13 mounted with reflector 14 and protective glass window 15. Only ultraviolet light is passed by filter 17 and since both metal and sealing compound are UV- opaque, light only impinges upon photomultiplier 16 in the presence of leaks. UV light is employed because the sealing compound may transmit optical wavelength light. The output of photomultiplier 16 may be used to control a sorting process. Filter 17 may alternatively be disposed between the can end and photomultiplier. <IMAGE>

Title: Improvements relating to wrap spring clutches
IPC: F16D27/105
Filed: 1979-10-05
Abstract: A wrap spring clutch enables drive to be made between a central drive shaft (1) and a drive member (2) carrying a sprocket (3). The drive member (2) is interconnected with a drum (4) through a helical clutch spring (5), a portion of the spring (5) being disposed loosely around a collar (10) which is integral with the shaft (1). The drum (4) is formed from a ferromagnetic material so that when an electromagnetic coil (8) is energised, the drum (4) will slow down causing the spring (5) to grip the collar (10) and thus connect drive through from the drive shaft (1) to the sprocket (3). Such a device is liable to fail if gaps are allowed to appear at positions (16 and 17) between relative moving parts. The parts are therefore kept in close contact by a spring loaded washer (11) carried by the drive shaft (1) and acting via a wear bearing (12). <IMAGE>

Title: Improvements Relating to Tunnelling
IPC: E21D11/38
Filed: 1980-02-05
Abstract: The invention is concerned with a method of constructing a lined tunnel using a tunnelling shield. In the method each ring section 4 of a tunnel lining is erected by first assembling its segments 5 to form the new ring section 4a in an unexpanded state within a tail skin 2 of the tunnelling shield while a thin rear extension 3 of the tail skin 2 overlaps the leading end of the previously erected and fully expanded ring section 4b and whereby an annular layer of resilient compressible material 6 is located around the newly assembled ring section 4a, the annular layer of resilient compressible material 6 being formed by layers of the material attached to the outer surfaces of the individual segments 5. The newly assembled ring section 4a is then pushed against the loading end face of the previously erected ring section 4b and is partially expanded so that the layer of compressible material 6 is partially compressed against the inside of the tail skin 2 and its extension 3 as shown. The tunnelling shield is then advanced until its thin rear extension 3 overlaps the leading end of the new ring section 4a, and the new ring section 4a is then further expanded until it reaches its fully expanded condition. <IMAGE>
