Novel substituted propanols of the general formula wherein X is hydrogen, fluorine, chlorine, bromine, or C 1-4  alkyl, and Y is either 2,6-dimethylmorpholino or 3,5-dimethylmorpholino, and the acid addition salts (including penicillinates) thereof, are prepared by reacting the corresponding phenyl Grignard reagent with a lower-alkyl 2-methyl-3-(2,6-dimethylmorpholino) or (3,5-dimethylmorpholino) propionate. Methyl 2 - methyl - 3 - (3,5 - dimethylmorpholino) propionate is made by heating a mixture of methylmethacrylate, 3,5-dimethylmorpholino and acetic acid. Therapeutic compositions contain the above novel substituted propanols or their pharmacologically acceptable acid addition salts as the active ingredient. The 2,6-dimethylmorpholino derivatives have an anoresigenic effect and the 3,5-dimethylmorpholino compounds can be used to protect animals against thiosemicarbazide and nicotine convulsions.

Filed: 1928-04-10
Abstract: 289,023. Barrett Co., (Assignees of Miller, S. P.). April 20, 1927, [Convention date]. Scrubbing and condensing processes.-Tar is distilled by spraying it into contact with hot gases produced from a battery of coal ovens or retorts, and the gaseous products are scrubbed with tar or pitch to give clean gases from which the oils are subsequently condensed, while pitch is obtained from the scrubbing operation. The ascension pipes 6 from part of a battery of coal retorts 5 lead to a short collector main 7 into which tar is sprayed through nozzles 14. The resulting vapours are led to a scrubber 38, where they are sprayed with tar or pitch from nozzles ,31, and then pass to a condenser 38. The tar from the hydraulic main is collected in a tank 13 from which it is pumped to the strays 14 through a preheater 25. Ammonia liquor is decanted through an outlet 23. By introducing tars and pitches of different characteristics through the sprays 31, pitches of different characteristics are precipitated in the scrubber 38 and are removed through a line 35 to a storage tank 36. Specifications 184,507, 286,278, 287,900, and 288,270 are referred to.

The cement may be portland cement or aluminate cement. The silica may have a particle size less than 10 microns and may be added as a colloidal solution. The suspension may be aqueous and contain up to 90 wt. per cent water, 10 to 80 wt. per cent silica particles as well as 0À001 to 80 wt. per cent surface active substance and 0-20 wt. per cent of an amphiphilic substance and/or hydrocarbon forming in the water phase a lyotropic liquid crystalline phase. The surface active substance may be sodium lauryl sulphate or nonyl phenyl polyethylene oxide glycol ether. The amphiphilic substance may be a carboxylic acid, alcohol, monoglyceride, phosphate, aldehyde, amine or an alkyl glycol ether having less than 3 ether groups. The hydrocarbon may be benzene, hexane or p-xylene. The surface of the concrete article may be made more durable and hydrophobic by being treated with a polymer (e.g polyurethane or silicon polymers or copolymers thereof). In examples, into concrete mixtures comprising cement, gravel and macadam were stirred additives comprising water, aryl glycol ether, silica (0À1 to 1 micron, about 0À1 micron or colloidal in size) and also, in most examples, pxylene. The concrete mixture of Example 14 also contained a lignosulphonate, red pigment and a red liquid paint.

[Classes 92 (ii) and 119] [See also Group XXXVII] Machine guns which normally fire live cartridges are by the provision of pelletfeeding means and means for controlling the supply or compressed air, adapted to discharge pellets for practice purposes. In place of the usual breech mechanism, a block having air supply passages 13, 28, lift valve 14 and pellet-feeding means 20, 17 is fastened within the gun casing by a bolt 11, so as to abut through the medium of a fibre packing 19 against the rear end of a tube 24 fitted as a liner to the ordinary machine gun barrel x. The normal cartridge-feed casing is removed and replaced by a casing 31 carrying an electric motor 23 which drives through reduction gear a cam 16 for operating the air-supply valve 14 and a spindle 30 carrying a notched pellet-feed member 17, Fig. 3, with spiral periphery for moving the pellets from the feed tube 20 to the support 19 immediately behind the bore of the tube 24. The nozzle conveying the compressed air is connected to the passage 13. The usual handle-block at the rear of the gun casing is replaced by a plug 5 carrying a spring-controlled switch button 2 which is pressed by a lever 1 to start the gun. Pressure on the button first closes contacts 4, 25, Fig. 2, to start the motor 23 at full voltage. Further pressure on the button closes contacts 4, 8 to place in the armature circuit a resistance 26 which can be varied to suit the speed of motor required for the desired speed of firing. Alternatively, the gun may be driven by clockwork.

Title: Improved method of manufacturing rubber articles from sensitized latex
Filed: 1949-04-25
Abstract: 659,136. Moulding rubber articles; treating sensitized latex. CHASSAING, F. April 25, 1949, No. 10941. Convention date, May 10, 1948. [Classes 70 and 87 (ii)] Rubber articles are obtained by moulding and coagulating sensitized latex to form a wall of rubber which is then subjected to a stress causing its elongation, and then released so that it contracts and expels a great amount of the serum, the resulting irregular surface wall thus obtained being then heated to about 60‹ C., thus causing a further contraction whereupon the wall may be very quickly dried. In an example, the mould consists of an inner portion in the form of a hollow sphere 31 (Fig. 16) provided with a neck 32 and made of plaster or any other brittle material, and an outer shell 33 consisting of two parts bolted together. Sensitized latex is then poured in to fill space 34 and the whole assembly heated in tank 35 to 60‹ C. to cause coagulation of the latex. The mould is then opened and the rubber sphere expanded with compressed air, the air released, the fragile inner mould portion crushed and the pieces removed from the neck and the rubber sphere then immersed in water at 60‹ C., causing the rubber to contract and assume a very smooth surface. In other examples an inner tube (Figs. 1-14, not shown) and a rubber sheet (Figs. 23-26, not shown) are produced.

A bipolar electrode comprises a plastic barrier member 21 having compartments 23, 24 to receive positive and negative active materials 12a, 12b. The compartments contain grids 25 which extend through the barrier and are welded together at 26. Conductive plastic films 27, 28 are placed between the grids and active material. After the parts have been assembled, the bipolar electrode so formed is compressed and heated so that the binder in the films becomes softened and unites the parts together. The rim 22 of the member 21 is threaded so that a number of electrodes can be screwed into a threaded casing 51, as shown in Fig. 1, adjacent electrodes being separated by insulating sheets 16b. Alternatively the electrodes may be enclosed in a casing by a moulding process. The active material 12a may consist of spongy silver. The material 12b may be zinc made by sintering compressed zinc oxide or by dispersing zinc particles throughout a binder. Mercury oxide may be mixed with the zinc or deposited on the surface of the electrode. Each separator 16b may consist of three sheets, the middle one consisting of a porous carrier of asbestos or synthetic resin impregnated with an ion-exchange resin, the outer sheets consisting of microporous polyethylene. The films 27, 28 may consist of polyethylene containing silver particles. The electrodes may be formed before assembly, or after the battery has been enclosed in its casing. In the latter case the electrodes and separators are impregnated with potassium hydroxide solution before assembly. Any hydrogen evolved during charging diffuses through the casing.
