Title: Manufacture of new compounds of the acridinium series
IPC: C07D219/08
Filed: 1933-05-13
Abstract: Acridinium compounds containing a substituted arsonic acid residue attached to the nuclear nitrogen atom are prepared by treating an acridinium compound, having both an alkyl group and an anion of a mineral acid or lower carboxylic acid attached to the nuclear nitrogen atom, with a water-soluble salt of an acylamino-arylarsonic acid.  The acridine nucleus may be substituted, e.g. by amino, alkyl or alkyloxy groups.  The products possess therapeutic properties.  An example is given of the treatment of 3 : 6-diamino - 10 - methylacridinium chloride with sodium p-glycollylaminophenylarsonate in aqueous solution. The samples furnished are prepared by the interaction of:--(1) 3 : 6 - diamino - 10 - methylacridinium chloride and 3 - acetylamino - 4 - hydroxy - 5 - chlorophenyl - 1 - arsonate; (2) 2 : 7 - dimethyl - 3 : 6 - diamino - 10 - methylacridinium chloride and sodium 4-glycollylaminophenyl - 1 - arsonate; (3) 3 : 6 - diamino - 10 - methylacridinium chloride and sodium 4 - acetylamino - 2 - phenoxyacetic acid - 1 - arsonate; and (4) 3 : 6-dimethoxy-10-methylacridinium chloride and sodium 4-glycollylaminophenyl-1-arsonic acid.  The formul  of the products are given.  The Specification as open to inspection under Sect. 91 also describes the use of aromatic or heterocyclic-aromatic arsonic acids containing no primary amino group; in addition, it states that the acridinium compound may contain an aralkyl or hydroxyalkyl group, in place of the alkyl group, attached to the nuclear nitrogen atom. Examples are given, not only of the processes now described with reference to Samples (1), (2) and (3) above, but also of the interaction of (4) 3 : 6 - diamino - 10 - methylacridinium chloride or acetate with sodium 2 : 4 - dihydroxyphenyl - 1 - arsonate, sodium benzoxazolone - 6 - arsonate and sodium 3 - methylbenzimidazole - 6 - arsonic acid, and (5) 3 : 6 - dimethoxy - 10 - methylacridinium chloride with sodium 4-phenylglycinamide - 1 - arsonate.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to loading machines
IPC: E21D9/12
Filed: 1944-07-21
Abstract: 590,555. Loading machines. JOY MANUFACTURING CO. July 21, 1944, No. 14002. Convention date, Sept. 6, 1943. [Class 78(i)] In a coal loading machine of the kind in which a loading conveyer projecting forwardly therefrom delivers to a conveyer disposed transversely thereto, the latter conveyer is movable longitudinally in opposite directions to project from either side of the machine and can be driven in opposite directions. The loading conveyer 77, Fig. 3, is mounted on a framework 76 which is pivoted to the machine at 83 and is adjusted by the piston 82 of a hydraulic cylinder 81. The upper end of the conveyer 77 is disposed above a transverse conveyer 100, Fig. 4, the upper run of which .is supported by a concave plate 103. Rods 130, which are curved similarly to the plate 103, are secured to the framework of the conveyer 100 and slide in recessed guide members 131 on the machine. This conveyer is moved longitudinally in opposite directions by cables 139, 142 each of which is anchored to the base of the conveyer and to one of the endless track units supporting the machine. Between the anchorages the cable 139.is passed round two pulleys 137 carried by a piston 134 and a pulley 138 mounted on the end of a cylinder 132. The cable 142 is passed round similar pulleys mounted on a piston and cylinder which are disposed oppositely to the piston 134 and cylinder 132. Pipes 72, 73, Fig. 1, connect the cylinders to hydraulic control valves 69, the arrangement being such that as pressure fluid is admitted to one cylinder, the fluid in the other cylinder is discharged to the oil tank 66. The cylinder 81 is connected by a pipe 71 to the control valves 69. An electric motor 56 drives a pump 60 which is connected by hoses 61, 62 to a four-way valve 63. The flow of oil into and out of the pump is reversed by turning the handle of the valve 63. This must be done when the motor 56 is reversed to drive the conveyer in the opposite direction. The inlet to the valve is connected by a hose 64 to the oil tank 66. The valve outlet is connected by a hose 68 to the control valves 69. The ends of the shafts 104, 106, which carry the sprockets of the conveyer 100, are provided with sprockets 113 around which passes a driving chain 114. This chain extends over idler sprockets 116, 117 mounted in brackets 121 and around a driving sprocket 118 which is connected by a spring-loaded clutch to a sprocket 57 driven by the motor 56. The brackets are pivotally mounted on the top of the transverse shaft 4 and are connected by a rod 123 slidably mounted in rotatable pins 122 projecting from them. Springs 124 mounted on the rods force the brackets towards each other. When one side of the chain 114 is under tension, the bracket on that side is forced downwards and the other bracket is swung upwards by the rod and springs to take up the slack on the other side. Stops 127 limit the downward movement of a bracket.

Filed: 1972-03-24
Abstract: 1388203 Rolling tubes MANNESMANN-MEER AG 24 March 1972 [31 March 1971] 14015/72 Heading B3 A feed mechanism for a cold pilger rolling mill incorporates two feed slides 14 and 15 for feeding a tube 1 between the rolls 3 of the mill, the slides being carried on right and left-hand threaded portions of a feed spindle 13. The slides alternately grip and release the tube and are shifted axially both by rotation of, and axial movement of, the spindle. The spindle is rotated through gears 19-26 and 28-30 from a shaft 4 which is driven from the reciprocating drive assembly for the stand 2 of the mill. A reversing clutch 27 determines the sense of rotation of the spindle 13 and hence the direction of movement of the slides. A pulley assembly 21 allows the speed ratio of the drive to be adjusted. Axial movement of the spindle is also effected by a lever 10 acting directly on the end of the spindle. The lever is pivoted at 16 and carries a cam follower 17 at one end which co-operates with a continuously rotating cam 9. By changing the position of the pivot 11 of the lever, the amount of axial movement of the spindle can be varied. When one slide 14 or 15 is feeding the tube, the other is returning to a feed position without gripping the tube so that it can, in turn, take over the feeding. The adjustable pivot 11 and pulley assembly 21 are used to provide a degree of deformation of the tube consistent with the tube material used.

Abstract: 1,181,703. Removing SO2 from gases. J. DERKA, R. KLIMECEK and V. VEVERKA. 28 March, 1967 [31 March, 1966], No. 14031/67. Heading C1A. SO2 is removed from waste gases in 2 stages, by contacting the gases (i) with an ammonium sulphite-bisulphite solution, which is regenerated (by boiling off an SO2/steam mixture then crystallizing out (NH4)2SO4) and recycled, and (ii) with the condensate obtained by cooling the SO2/steam mixture, this condensate then being passed to the first stage. The SO2/steam mixture may be precooled (and desorbed of any NH3) by passing it in heat exchange (14) with the loaded solution from the first stage absorber (13) before regeneration, and H2O is then condensed out (at 16) by cooling to 35‹ C. The condensates from heat exchanger (14) and condenser (16) are passed in heat exchange (17) with the SO2/steam mixture before it enters 14 to desorb any SO2, then cooled to 35‹ C. (18) and passed to a receiver (22), to which NH3 is also fed. Water may be added to receiver (22) or drawn off from cooler (18) as necessary. The second stage solution circulates through receiver (22) and second stage absorber (23) where it contacts the gas from absorber (13). The loaded solution from absorber (13) is regenerated (15) by boiling at 105-110‹ C., and cooled to 35‹ C. (19 and 20) to crystallize out (NH4)2SO4 which is centrifuged (21), the liquors being mixed with the solution from 22 and recycled to absorber (13). Some NH3 may also be added to the first stage circuit, and H2SO4 may be introduced, e.g. into regenerator (15) to increase the yield of (NH4)2SO4. This H2SO4 may have been used to dry the product SO2. The numerals refer to Fig. 2 (not shown).
