Title: Improvements in or relating to the reduction of aromatic nitro-compounds by means ofalkali metal amalgams
Filed: 1949-04-01
Abstract: Aromatic nitro-compounds are reduced by an alkali metal amalgam and a reagent which is decomposed by the amalgam to give free hydrogen, the nitro-compound, amalgam and decomposition agent being brought together in the presence of carbon which may be impregnated with ferric chloride.  The decomposition agent may be water together with a solvent for the nitro-compound, e.g. when reducing nitrobenzene it may be 50-80 per cent aqueous alcohol, especially 70 per cent alcohol.  The carbon may be in the form of graphite, coke, electrode carbon or activated carbon (powder or moulded).  By this process, nitrobenzene is reduced progressively to azoxybenzene, azobenzene and hydrazobenzene, practically no aniline being formed.  Graphs are given of the amount of alkali metal used for each stage of reduction, using graphite lumps with or without impregnation with ferric chloride solution.  The process may be carried out continuously, the reactants being brought together and a corresponding quantity of product simultaneously removed.  Suitable apparatus is shown for continuous operation in two or more stages, the amalgam and solution moving in counter-current and reduction taking place successively in different reactors.  The hydrazobenzene produced may be separated from azobenzene by crystallization from alcohol. Specifications 200,167 and 203,059 are referred to.  The Specification as open to inspection under Sect. 91 refers to the reduction of organic and inorganic compounds in general by bringing them into contact with alkali metal amalgam and a decomposition agent in the presence of any substance or substances by which the decomposition is accelerated. The reduction of aromatic and aliphatic aldehydes and ketones to the corresponding alcohols is mentioned.  This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 refers to the reduction of inorganic and organic compounds in general by bringing them into contact with an alkali metal amalgam, a reagent which is decomposed by the amalgam to give free hydrogen (e.g. water) and a substance or substances to accelerate such decomposition.  The decomposition accelerator may be carbon in the form of graphite, coke, electrode carbon or activated carbon (powder or moulded) and may contain iron, introduced, e.g. by impregnation with aqueous ferric chloride and drying.  The process is stated to be applicable to the preparation of sodium hyposulphite from sodium bisulphite.  This subject-matter does not appear in the Specification as accepted.

Title: A process for improving effects mechanically produced on textile materials containing cellulose
IPC: D06Q1/08
Filed: 1936-03-30
Abstract: Pattern and cr<\>zepe effects, pleatings and like mechanical effects on natural or artificial cellulose piece-goods, knitted fabrics, loose material and threads, are rendered stable to water by subsequent conversion of the cellulose, with rentention of its structure, into a cellulose ester.  If the esterification process involves treatment with an aqueous solution, the pattern &c. effect must be produced after this step of the process In the case of loose material, or thread, the effect takes the form of wave or crimping. In examples, viscose piece-goods are impregnated with potassium acetate solution, dried, then pressed on an embossing calender, and finally treated with acetic anhydride dissolved in benzine; cotton piece-goods are passed through an embossing calender and then through a solution of acetic anhydride and zinc chloride in acetic acid; cotton piece-goods are pleated by hot pressing, and then treated with a solution of benzoyl chloride in pyridine.  Other esterifying agents that may be used are propionic, butyric, valerianic, isovalerianic, monochloracetic, and phthalic anhydrides, and acetyl, propionyl, butyryl, palmityl, stearoyl and benzoylchlorides.  The Specification as open to inspection under Sect. 91 refers to treatment with an etherifying agent such as benzyl chloride.  This subject-matter does not appear in the Specification as accepted.

The apparatus comprises a rod 10 extending from the pilot's pedals and connected to a link 13 having bifurcated arms connected by a cross pin 34 which extends through a slot 24 in a link 16. The link 16, which supports an actuator 28, the piston-rod 30 of which is connected by a pin 32 to link 12, is mounted by a bifurcated lug 19 and pin 18 on a U-shape frame 22 which is supported on fixed structure by pivots 36 and connected at 38, 42 to a trim actuator 40. The upper end of link 16 is connected to an output rod 14 extending to the pitch control mechanism. The actuator 28 comprises a cylinder 44 and piston 46 connected to rod 30, the piston being urged to the bottom of the cylinder by a spring 48. The piston-rod 30 is hollow to accommodate a hollow rod 52 fastened by nut 54 and housing a piston 56 urged downwardly by a spring 60 and extended upwardly by a rod 58 terminating in a head 65 which positions locking balls 66 above a shoulder formed by an enlarged bore 67 in rod 30. Pressure fluid inlet and outlet connections 72, 80 in cylinder 44 connect to a control valve (not shown) automatically responsive to the position of the collective pitch control stick and engine torque, so that when the rotors go into autorotation pressure fluid admitted at 72 urges piston 56 and head 65 upwardly, thereby freeing balls 66 and allowing pressure fluid acting on piston 46 against spring 48 to move rod 30, and link 12 upwardly until pin 34 reaches the top of slot 24. In this condition movement of rod 10 will produce a direction of movement of rod 14 opposite to the direction which would apply when pin 34 was seated at the bottom of slot 24.

Abstract: 913,726. Dispensing measured quantities by means of screws. HESSER, MASCHINENFABRIK-A.G., Fr. March 15, 1961 [March 18, 1960], No. 9426/61. Class 78 (1). [Also in Group XVII] Powder from shoot 40 is distributed at 41 on to rotating disc 4. Disc 4 carries a plurality of hoppers 3 each having its respective discharge screw 1. The material falls from disc 4 into a hopper 3 and is discharged therefrom in predetermined amount by screw 1 into the containers P carried by belt 5b. Clutch mechanism.-Screw 1 is driven from fixed rack 7 via gear 8, clutch 27, 32 and gears 11, 12. Screw 1 is driven for a predetermined number of revolutions in order to insert into respective container P a predetermined quantity of powder. In order that the number of revolutions of screw 1 should be exact it is arranged that the two clutch parts 27 and 32 should be at the same speed when they are brought into engagement. To effect this, clutch part 27 carries a nut which engages with helix 30, and the said part is also operated by cam rail 15 through pivoted lever 17 so that when gear 8 begins to be driven by rack 7 clutch part 27 is moved downwards by cam 15. The two rotary movements thus imparted to clutch part 27 cancel out each other so that the two clutch parts 27 and 32 come into engagement when they are both substantially at rest. Cam rail 15 is carried by a cam piece 15a and this in turn is carried by arm 60 adjustable at 61 when motor 68 is operated. By this means the operation of arm 17 may be set to give the predetermined number of revolutions for screw 1. Likewise arm 60 carries cam rail 46 which operates roller 47 to actuate brake 42 to bring the screw 1 to rest. Agitators 75 and 76 are caused to rotate inside hopper 3 by a drive from shaft 14 via gearing 78, 79 and 77.
