Title: Improvements in and relating to new reactive dyestuffs containing azo-diazine groups
Inventor: RAZAVI DJAVAD
IPC: C09B62/24
Filed: 1964-05-22
Abstract: The invention provides water-soluble reactive azo-diazine dyes which contain at least one group of formula <FORM:1071041/C4-C5/1> in which one X is a halogen atom and the others are halogen atoms or are substituted or unsubstituted amino groups.  The dyes may be azo, anthraquinone or phthalocyanine dyes, and may be prepared by coupling the diazo derivative of an aromatic primary amine with barbituric acid and reacting the products with phosphorus oxychloride, the dyestuff product may then be reacted with ammonia or an amine such that at least one halogen atom remains in the group as above. Red-blue shades are obtained on cellulosic materials.ALSO:Water-soluble reactive dyes which contain at least one group of the formula <FORM:1071041/D1-D2/1> in which one X is a halogen atom and the others are halogen atoms or are substituted or unsubstituted amino groups are used to dye cellulosic materials. Normal padding or printing processes in presence of acid removing agents followed by steaming or dry-heat fixing at temperatures of 120-160 DEG C are employed.

Specified compounds are (4-see-amylbenzyl) - tris - n - amyl-, (4 - see - amylbenzyl)-trimethyl-, and (4-see-amylbenzyl)-phenyldimethyl-ammonium chloride.  The compositions also contain an inert carrier, which may be water together with a dispersing, emulsifying or wetting agent, e.g. a mixture of a polyethylene glycol derivative and an alkyl benzene sulphonate.  Dispersing or emulsifying agents are desirable when oil-in-water emulsions (with petroleum or coal tar oils) are required.  The active compounds may be employed in dusting preparations or in conjunction with known water-insoluble insecticides and/or fungicides in organic solution.

IPC: B22F3/02
Filed: 1954-07-26
Abstract: 807,434. Making briquettes. COAL INDUSTRY (PATENTS) Ltd. July 26, 1955 [July 26, 1954 ; Oct 14, 1954], Nos. 21775/54 and 29633/54. Class 87(2). Briquettes are made by compressing particles in a closed mould 10, Fig. 1, shaped to produce a main portion with a tapered zone 12b and a protruding portion of smaller cross-section 12a which is then forced wholly or partly into the main portion whereby the mass undergoes angular shear strain of such magnitude and distribution as to produce a briquette of high strength, the required conditions being found experimentally as disclosed in Specification 807,433. A plate 11 is moved sideways and the briquette is ejected by further movement of the plunger 13. In a double plunger mould, Fig. la, the particles are first lightly pressed by a plunger 22 in a support 23 and the compacted mass is moved in the support to the position shown in dotted lines and then pushed into the mould 20 against a stationary plunger 24 and the end of a sleeve 25, forming a body P with a tapered zone and a plug, Fig. Ic. With the plunger 22 stationary the plunger 24 advances and forces the plug into the main compressed body. The plunger 24 then stops and the plunger 22 retracts, followed by the plunger 24 which, by a collar 26, advances the sleeve 25 and thereby ejects the moulded briquette. The plungers 22, 24 may be operated by single speed reversible hydraulic rams under the control of cams. The length of the compressed plug depends on the position of the collar 26. The arrangement in Fig. 1, may be duplicated by having an additional plunger opposite the plunger 13 and a throat and tapered portion corresponding to the mould portions 12a, 12b.

Title: An invention for the cutting of sugar cane and similar agricultural products by mechanical power
IPC: A01D45/10
Filed: 1919-09-08
Abstract: 156,298. Wertheim, M. Sept. 8, 1919. Sugar-cane cutting-machines.-A machine for cutting sugar canes comprises means for cutting the canes near the ground, for levelling and cutting off the tops, and for discharging the cut canes on to the ground. The machine shown comprises a timber and metal frame 1 mounted on four adjustable wheels 4, the axles of the front ones being mounted in brackets on their angular standards 5. The canes are cut by a rotary knife 40 and fall into a pivoted and approximately balanced carrier 19 in a trough 16 having a splayed upper end which may be formed of tubing 17 and woven wire. After the canes have been loosely bound, the carrier is raised and turned into a vertical position so that the top ends of the canes are levelled by contact with the bottom of the trough, after which the binding-cord is tightened. The carrier is then returned to its original position and pushed lengthways on suppcrting-rollers 19x until the canes are in a position to be topped by a rotary knife 53, which is brought down upon them. After the tops have been removed, the canes are discharged by again turning the carrier into the vertical position and releasing the binding cord or chain. The canes are guided into the trough 16 by guide arms which are adjustable by means of cords and weights. The trunnions 20 of the carrier 19 work in rightangled slots in the trough 16 and carry lever arms 21 which engage with rollers 22 when the carrier is raised, and turn it into the vertical position. The carrier is raised by means of ropes or chains wound on drums 26 on shafts 25, 30 which are connected by spur and chain gearing and are operated by a handle 24. The cutter 40 is driven by flexible shafting 41 and a clutch from a shaft 51 driven by chain gearing from an engine 42, which is cooled by means of a fan 63. The cutter 40 is manipulated by means of handles 43 and is provided with a casing 49 and with ball bearings. The topping-cutter 53 is mounted in ball bearings carried by a pivoted and counterweighted arm 54 which may be held in position by a segment 57 and pin 58. The cutter 53 is driven by chain gearing and a clutch from the shaft 51, and is provided with a casing 62. The machine may be propelled by the engine 42, or drawn by animals. The carrier 19 may be operated by power from the engine. Two or more carriers may be employed. In a modification, the machine has six wheels, the central pair of which is replaceable by others of different size, the carrier is raised by means of racks and pinions, and the topping-cutter is movable laterally and is adapted to be thrown back from operative to inoperative position by means of a handle pivoted on its shield.
