Abstract: 2-Amidobenzimidazole compounds of the structural formula <FORM:1111957/C2/1> wherein A is methyl or phenyl; X is oxygen or sulphur; R is hydrogen, alkyl of 1 to 10 carbon atoms, hydroxyalkyl of 1 to 10 carbon atoms, or benzyl; R1 is hydrogen, alkyl of 1 to 10 carbon atoms, or acyl of 1 to 10 carbon atoms; and Y and Z are hydrogen, alkyl of 1 to 10 carbon atoms, alkoxy of 1 to 10 carbon atoms, trifluoromethyl, amino, alkylamino, dialkylamino, cyano, acylamino, halo, hydroxy, nitro, alkyl-thio, carboxy, carbalkoxy, carbamoyl, alkyl-carbamoyl, or dialkylcarbamoyl, all of the undefined alkyl groups having 1 to 4 carbon atoms, are prepared by condesing a 2-amino-benzimidazole with a compound of formula <FORM:1111957/C2/2> preferably in the presence of a base in a solvent, e.g. pyridines. Compounds of formula I in which Y or Z is amino are prepared of catalytic reduction of the corresponding nitro compound preferably using a palladium-on-carbon catalyst.  Alternatively compounds of Formula I may be prepared by reacting the compound formed by reacting cyanamide with the selected carboxylic acid chloride in the presence of an acid-acceptor, e.g. pyridine or triethylamine, with an appropriately substituted o-phenylene diamine.  Compounds in which X is sulphur may be prepared by reacting the corresponding compound in which X is oxygen with phosphorus pentasulphide, preferably in a solvent.  The compounds of Formula I where R1 is alkyl and R is hydrogen are prepared by treating o-phenylene diamine with an alkyl isocyanate to form an alkyl o-aminophenylthiourea, which is cyclized to form a 2-alkylaminobenzimidazole, which is reacted with benzoyl or acetyl chloride to yield a 2-(N-alkylacylamino)benzimidazole. 1-Methyl-2-acetamidobenzimidazole and 2-(N,N-diacetylamino) - 1 - methylbenzimidazole are both prepared by the reaction of acetic anhydride with 1-methyl-2-aminobenzimidazole. Acid addition salts may be prepared in conventional manner.ALSO:Anthelmintic compositions comprise as active ingredient a 2-amidobenzidazole of the formula <FORM:1111957/A5-A6/1> wherein A is methyl or phenyl; X is oxygen or sulphur; R is hydrogen, alkyl or hydroxyalkyl of 1 to 10 carbon atoms or benzyl; R1 is hydrogen, alkyl or acyl of 1 to 10 carbon atoms; and Y and Z are hydrogen, alkyl or alkoxy of 1 to 10 carbon atoms, trifluoromethyl, amino, alkylamino, dialkylamino, cyano, acylamino, halo, hydroxy, nitro, alkylthio, carboxy, carbalkoxy, carbamoyl, alkylcarbamoyl or dialkylcarbamoyl, all of the undefined alkyl groups having 1 to 4 carbon atoms, or a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutical carrier.  The 2-amidobenzimidazole is preferably 2-benzamido-benzimidazole or 2-acetamidobenzimidazole and specified salts are the hydrochloride, hydrobromide, sulphate, phosphate, acetate or cyclohexylsulphamate. The compositions are administered orally in the form of an animal feed, drench or bolus, capsules, liquids or tablets which may be emperic coated or adapted for sustained release.

Title: Improvements in high frequency dynamo-electric machines
IPC: H02K19/20
Filed: 1919-09-16
Abstract: 166,259. Glass, A. M., (Lorenz Akt.-Ges., C.). Sept. 16, 1919. High-frequency machines; inductor-alternators; rotary converters; rotary machines; exciting; cores.-A high-frequency alternator comprises a toothed rotor, a smooth stator, an armature winding arranged in the stator, and an exciting winding also arranged in the stator in slots parallel with the rotor axis. In a modification the stator is formed with teeth of such a width that the width of a rotor tooth is equal to the combined widths of a tooth and a slot in the stator. In each of these constructions the total reluctance of the path of the exciting flux remains constant for all positions of the rotor. The exciting winding e may be concentrated in two slots in the stator or it may be distributed around the stator as shown in Fig. 4. The machine may be constructed as a, self-exciting generator by providing a continuous-current winding g, Fig. 10, in the rotor slots and connecting it to a commutator from which current is taken to the exciting winding. The commutator brushes may also be connected up to an external circuit so that the machine may function as a double current generator. The machine may be run as a rotary converter by supplying continuous current to the commutator winding. In order that the converter may be self-starting in all positions of the rotor, the latter is formed with oblique teeth, the deviation of which from the normal is less than 3/4 of the tooth pitch. The machine may be used as an ignition and lighting generator. For this purpose it is preferably provided with a permanent ring-shaped magnet N, S, Fig. 12, for producing an initial field. The ignition and lighting circuits are connected to the alternating-current winding w. In a further modification, particularly for use in wireless telegraphy, the machine is adapted to produce two alternating currents of different frequencies. The rotor is provided with a winding of the ordinary drum armature type connected to two slip-rings. The frequency of the current produced in this winding will correspond to the number of the principal field-magnet poles. The current of low frequency may be superimposed on the high-frequency current by connecting the rotor winding w, Fig. 7, in series with the exciting winding e. A mono-axial winding short-circuited on itself may take the place of the rotor winding w.

The air nozzle m, Fig. 2, has an internally threaded part engaging the stem of a stud p by means of which its position in relation to the nozzle o may be adjusted. In place of an eccentric air nozzle the nozzles may be concentric as shown at o, m, Fig 4, in which case the cover is locked in position by a central stud s, provided with a water passage, the amount of atomization being regulated by screwing the nozzle m more or less closely to the nozzle o. The liquid filter q is mounted as shown and a spring loaded valve r is provided in the liquid passage which may be regulated from outside the casing. This arrangement of filter and valve may be applied to the atomizer shown in Figs. 1 and 2 and the liquid nozzle may be provided with a screwed stem so as to hold the cover on the casing and with a body part of the form shown in Fig. 4. Interchangeable caps may be provided so that either the eccentric or concentric spraying nozzles may be used.

Title: Aromatic polycarbonates and polymers thereof
IPC: C08F18/08
Filed: 1944-11-22
Abstract: Esters of the general formula <FORM:0585775/IV/1> in which R is a hydrocarbon radical of the benzene series, X is hydrogen, alkyl or halogen, n is an integer from two to six, are obtained by reacting a polyhydric phenol with an allyl haloformate corresponding to the allyl radicals to be introduced into said phenol.  An acid acceptor may be present to take up the hydrohalic acid generated.  Specified haloformates are allyl, 2-alkallyl in which the alkyl group contains one to four carbon atoms, chlorallyl and bromallyl.  All polyhydroxy benzenes may be used, e.g. catechol, resorcinol, pyrogallol, orcinol, hydroquinone, phloroglucinol and hydroxy hydroquinone.  Specified acid acceptors are pyridine, piperidine, dimethyl aniline and alkali and alkaline-earth metal hydroxides, carbonates and acid carbonates. In examples: (1) allyl chloroformate is added drop-wise to a solution of catechol in pyridine at -10 DEG  C., producing catechol bis-(allyl carbonate); (2) resorcinol bis-(allyl carbonate) is produced as in (1) using resorcinol instead of catechol; (3) pyrogallol tris-(allyl carbonate) is produced as in (1) using pyrogallol instead of catechol; (4) hydroquinone bis-(allyl carbonate) is produced as in (1) using hydroquinone instead of catechol.  Polymerization products.-The compounds described above may be polymerized or copolymerized by the use of ultra-violet light or with a small amount of a polymerization catalyst such as benzoyl peroxide.  Copolymers are obtained by interpolymerization of two or more of the above esters, or mixtures of these esters with other monomers, particularly styrene, acrylonitrile, methacrylonitrile, methyl methacrylate, ethyl methacrylate, butyl acrylate, butyl methacrylate, vinyl chloride and vinylidene chloride.  The esters may be polymerized also in aqueous emulsion in the presence of an emulsifying agent, e.g. sodium oleate. The products in the examples are polymerized by heating with benzoyl peroxide.  The Specification as open to inspection under Sect. 91 also describes an alternative process consisting in reacting phosgene with the phenol and treating the resulting chloroformate with allyl alcohol to produce a phenol allyl carbonate.  This subject-matter does not appear in the Specification as accepted.
