Title: Aliphatic mercaptoanilides and their use as herbicides
Inventor: LAUTERBACH RUDOLF
IPC: A01N33/10

Abstract: 1,141,183. Aliphatic mercaptoanilides. FARBENFABRIKEN BAYER A.G. 8 Aug., 1967 [9 Sept., 1966; 9 March, 1967; 11 April, 1967], No. 36371/67. Heading C2C. [Also in Division A5] The invention comprises aliphatic mercaptoanilides of the formula in which R 1  denotes an aliphatic hydrocarbon radical of 1-8 carbon atoms which may be substituted by halogen atoms and (or) hydroxy, alkoxy, carboxy, phenoxy or hydroxyphenoxy groups, R 2  denotes (a) an aliphatic hydrocarbon radical of 1-9 carbon atoms, which may be substituted by halogen atoms or hydroxy and (or) alkoxy groups or (b) a cyclopropyl, cyclobutyl or alkoxycyclopropyl group, R 3  denotes hydrogen or an alkyl group of 1-3 carbon atoms, X 1  denotes a hydrogen or halogen atom, an alkyl or alkoxy group of 1-4 carbon atoms or a haloalkyl group and X 2  denotes a hydrogen or halogen atom or a methyl or ethyl group. Many specific instances of the radicals R 1  and R 2  are given, including some alkyl, alkenyl or alkinyl groups which may carry substituents, as specified above. The compounds may be prepared (a) by reacting an arylamine of the formula with an appropriate carboxylic acid halide in the presence of a solvent and an acid-binding agent, or (b) by reacting an arylamine as defined above with an appropriate carboxylic anhydride, or (c) by reacting an arylamine as defined above with an ester of an appropriate carboxylic acid and an alcohol of 1-6 carbon atoms or phenol, or (d) by reacting an isocyanate of the formula with an appropriate carboxylic acid, carbon dioxide being split off, or (e) by reacting an arylalkyl ketone of the formula with hydroxylamine to yield the corresponding oxime, which is then subjected to the Beckmann re-arrangement. Method (d) is not applicable to the preparation of alkylmercaptoanilines which contain a carboxylic or hydroxy group in the side chain or which are alkylated on the nitrogen atom, and method (e) is applicable only when R 2  in the first formula above denotes an alkyl radical of 1-9 carbon atoms. Numerous examples are given. The products are useful as herbicides (see Division A5). 3 - Chloro - 4 - allylmercaptoaniline, an intermediate in the process, is prepared by treating 3,4 - dichloronitrobenzene with sodium sulphide to yield 2 - chloro - 4 - aminothiophenolate, which is then reacted with allyl chloride. A number of other intermediates obtained similarly from p-chloronitrobenzenes are listed.

Title: Anesthetic compositions comprising 2, 2, 2-trifluoroethyl vinyl ether and processes for producing the same
Inventor: SHUKYS JULIUS GEORGE
IPC: C07C43/14
Filed: 1955-12-19
Abstract: The invention comprises 2,2,2-trifluoroethyl vinyl ether free of toxic impurities such as acid-sensitive toxic impurities, and the preparation of substantially pure 2,2,2-trifluoroethyl vinyl ether by reacting 2,2,2-trifluoroethanol with acetylene in the presence of an alkali metal 2,2,2-trifluoroethanolate and washing the distillate obtained therefrom with acid.  The final step in the process may be carried out by washing the distillate with water, then with aqueous mineral acid, then with water and finally with aqueous caustic soda to remove the acid, drying the product obtained and distilling to obtain the desired compound.  A suitable mineral acid is hydrochloric acid.  The 2,2,2-trifluoroethyl vinyl ether may be stabilized by the addition of a pharmaceutically acceptable alkaline stabilizer such as an alkyl, cycloalkyl, or aryl amine particularly phenyl alpha naphthylamine, o- and p-phenylene diamine, triethanolamine, dicyclohexylamine and di-(2-ethylhexyl)amine, and the stabilizer may be added before or after each distillation in the above process.  One detailed example is given of the above process.ALSO:An anaesthetic composition contains oxygen or an oxygen containing gas such as air and as the active compound 2,2,2-trifluoroethyl vinyl ether free of toxic impurities, e.g. acid-sensitive acid impurities.  The composition may also incorporate a pharmaceutically acceptable alkaline stabilizer for the active ingredient such as an alkyl, cycloalkyl or aryl amine-particularly phenyl alpha-naphthylamine, o- and p-phenylene diamine, triethanolamine, di-(2-ethylhexyl)-amine and dicyclohexylamine.  Thus the composition may comprise the 2,2,2-trifluoroethyl vinyl ether, nitrous oxide and oxygen with or without the stabilizer.  The anaesthetic compositions may be prepared by volatilizing the 2,2,2-trifluoroethyl vinyl ether and mixing oxygen which may contain controlled amounts of a gaseous vehicle therewith.

[Also in Group XL (b)] A delay line or other sectionalized network comprises a stack of insulated panels having circuitry printed on them. The front face (Fig. 1) of each panel may have an inductor winding 1 and a capacitor electrode 2 printed on it. The reverse face (Fig. 2) carries the other electrode 4 of the capacitor and a lead 5 connected through the panel to the centre of the inductor winding 1. The material of the panel forms the dielectric of the capacitor. The electrode 4 may, like the electrode 2, be provided with a gap. The panels are mounted between three rods 11 connected at either end to the corners of triangular frames 9,10. Nuts 12 on the ends of the rods 11 enable resilient spacing washers 13 between the panels to be compressed and thus provide a degree of adjustment of the electric and magnetic coupling between the panels. The electrodes 4 of the panels may be earthed through one of the rods 11. Tappings may be made to terminal extensions 14 of the electrodes 2. Damping resistors may be connected across each panel circuit and may be constituted by graphite deposits on the panels.

The expansion and exhaust strokes are thus rendered longer than the induction and compression strokes. The stroke differences may be varied by using helicoidal wheels to connect the shafts 20, 14, one of the wheels being axially slidable. During the working stroke the angle between the lever 16 and the crank connecting it to the shaft 14 remains approximately constant.

The supply of material to a high frequency drying zone is controlled by an arrangement responsive to the D. C. power input of the generator producing the high frequency drying field. As shown, the amount of granular or pulverulent material 3 supplied to a heating zone 2 by a uniformly moving conveying means is controlled by a delivery means 8, such as a throttle, responsive to a control signal derived over a regulator 6 from the D. C. input 4 of the high frequency generator 1 supplying the heating zone 2. The arrangement ensures that the material is supplied to the zone 2 at a rate such that the generator 1 operates at full power without overloading. The control signal may be compared with a predetermined reference signal 7 in the regulator 6.

Dec. 12, 1930, No. 37598. [Class 3 (i).] In route and destination indicators and other display apparatus comprising a band wound on and off two rollers one of which is manually operated, one roller 13 is provided with a spring retractor and a stationary casing 14. The casing 14 has a longitudinal slot 15 through which the band 69 passes, and is furnished at its ends with tongues 16 which removably engage slots 17 in the housing 10. The band is provided at its free end with a pulling tab 24 and with a rod 23 which detachably engages hooks 22 at the ends of the manually operated roller 19. Various devices are described for preventing undesired rotation of the roller 19 by the pull of the spring roller 13. Fig. 2 shows the employment of worm gearing 26, 27 between the handle 25 and the roller 19. Fig. 5 indicates a handle shaft 33 slidable non-rotatably in an extension 30 of the roller 19. The shaft 33 has fixed to it one half 36 of a dog clutch, and a spring 38 normally presses this half 36 against the stationary other half 34. Inward pressure on the handle frees the clutch for rotation. Fig. 6 shows a handle 25, which when forced inwardly against a spring 40 brings its squared shaft end 44 into engagement with the roller 19. A locking pawl 49 pivots under the control of a ring 46 on the handle shaft into and out of engagement with teeth 53 on the roller 19. In Fig. 7 is depicted a brake formed of two spring- pressed ring blocks 58, 59 bearing respectively on the handle and on a stationary abutment 56. The spring 60 is preferably wound in such a direction that it tends to uncoil by rotation of the roller 19 in the direction in which it tends to be pulled by the roller 13, thus increasing the axial pressure on the blocks 58, 59.
