Title: Manufacture of intermediate products for dyestuffs
IPC: C07C65/11
Filed: 1922-03-18
Abstract: The reaction between 1-oxynaphthalene-2-carboxylic acid and a tetrahalogenmethane in presence of a neutralizing agent as described in the parent Specification yields, besides a dyestuff, 4 : 41-dioxy - 1 : 11-dinaphthylketone-3 : 31-dicarboxylic acid and 1-oxynaphthalene-2 : 4-dicarboxylic acid which may be isolated from the reaction product by taking advantage of the differences between the solubilities of their alkali and alkaline earth salts.  According to examples (1) the alcoholic mother liquor from the dyestuff of example 3 of the parent Specification is acidified and the precipitate filtered and dissolved in sodium carbonate; by salting out the disodium salt of 4 : 41-dioxy-1 : 11-dinaphthylketone-3 : 31-dicarboxylic acid is precipitated; on acidification the filtrate precipitates 1-oxynaphthalene-2 : 4-dicarboxylic acid which is purified by extracting with baryta water and acidifying the extract: (2) the aqueous mother liquor from the dyestuff of example 2 of the parent Specification is similarly treated; in this case the oxyketone-dicarboxylic acid may first be isolated by salting out and then the dyestuff and 1-oxynaphthalene-2 : 4-dicarboxylic acid successively by cautious acidification; the dyestuff may also be separated first as magnesium salt and the other products isolated from the filtrate.  The formation of dyestuff in this reaction may be diminished by increasing the proportion of tetrachlormethane and using diluted caustic potash as neutralizing agent.

Filed: 1974-02-22
Abstract: 1427865 Ice cream manufacture GLACIER INDUSTRIES INC 22 Feb 1974 [13 March 1973] 8181/74 Heading A2B [Also in Division B8] A carriage 20 (Figs. 3-6) is periodically accelerated from rest up to the speed of an adjacent endless conveyor, the carriers 2 (Fig. 3) of which, support either ice cream blocks 4, or ice cream cones in recesses A, the carriage then performing respectively either a stick insertion or a cone-filling operation. In the event of faulty operation causing jamming of the carriage 20, the drive means of the latter is disengaged. Sticks 5 are contained in a magazine 18 carried on the frame of the apparatus. A pusher 94 is reciprocated by a piston/cylinder 100 to push out a stick 5 from a groove 92 in the upper surface of the carriage 20. Each stick 5 passes to the groove 92 as the latter passes under an opening 93 in line with the shoot 18. The carriage has ball bearing bushes 54, 54, which run on rods 22, 22, under the action of a drive bar 26. Movement of the latter is generated by the action of a cam mechanism (Fig. 2). Synchronisation of the carriage with the conveyor may be achieved by adjusting a frame (88) (Fig. 10, not shown) carrying jockey wheels (68) (76) about which the drive chain (64) for the cam 42 passes. The motion of the drive bar 26 is conveyed to the carriage via a follower wheel 48 (underneath plan view Fig. 6) which is driven by a piston cylinder 52 so as normally to engage a recess 46 in the bar 26. In the event of a jam, the follower 48 is forced out of the recess 46, and this causes actuation of a microswitch 56. By the action of pneumatic circuitry (Fig. 7, not shown) the pressure in the cylinder 52 is reversed, so as to completely release the bar 26 from the carriage 20, and also sound an alarm. When the apparatus is used for filling cones from a filler device (8) (Figs. 1 and 11, not shown), a connecting rod 28 Fig. 2 between the bar 26 and the follower 30 of the cam 42, is replaced by a shorter connecting rod linking with the device 8.
