Abstract: 1,247,450. Packaging. ILLINOIS TOOL WORKS Inc. 18 Sept., 1969 [18 Sept., 1968], No. 46102/69. Heading B8C. Cans 10, frictionally-retained in a plastics carrier 16 by the upturned lip 24 of each canreceiving aperture in the carrier, are each individually rotated in the carrier until its respective label or other identifying mark faces outwardly. Groups of cans assembled in their respective carrier are advanced by a continuously-driven conveyer 30 (Fig. 8) to a clamping station 40 whereat a pair of opposed pivotable and reciprocable clamps 44, 46 (Fig. 1) engage the first of the succession of can packs and transfer the first can pack to a working station 42 at which the individual cans are rotated to the desired orientation. The clamps are guided on longitudinal rails 36, 38 and are each reciprocatably driven by a cam and crank disc 56, 58 through a slotted crank 86, 88 and connecting rod 98, 100 so that, after the clamps engage the first of the can packs, the clamps are accelerated to separate the first pack from the successive packs. During this movement, enlarged cam segments 132, 134 on the crank discs acting through cam rollers 136, 138, 148, 150, Fig. 5 (not shown), on cam surfaces hold the clamps in engagement with the cans. On reaching the working station 42, the cam segments are no longer effective and a spring 126 pivots the clamps laterally away from the cans and holds them in this position whilst they are reciprocated back to the clamping station for engagement with the next can pack. At the working station, the top of each can is simultaneously raised into frictional engagement with a respective one of a plurality of continuously driven rotating pads 164 (Fig. 2) by a respective one of a plurality of heads 166, which are carried on a lifting frame 174. The frame is raised by cam and cam follower linkage 176, 178, 180, 184, Fig. 3 (not shown), so that each head urges each can upwards into driving engagement with its respective pad. Each head is rotatably mounted on a spindle 170 which is supported in a spring- loaded cup 192. Each cup is slidably mounted in a sleeve 172 and is held in an extended position therein by a latch plate 202. On engagement of the cans with the pads 164, the cans are rotated in the carrier until a photo-cell 216 associated with each can is actuated by a label or mark on the can when the can reaches its desired orientation and energizes a solenoid plunger 214 (Fig. 2) to release the latch plate so that the respective cup and head are urged downwardly by the cup spring 200 thus lowering and declutching the respective can from its drive pad. When all the cans of the pack have been thus orientated, the lifting frame is lowered, this movement automatically raising the cup against the cup spring to its extended position and resetting the latch plate to hold the cup in the extended position. The next pack is moved into the working station and pushes the processed pack on to a discharge conveyer 34.

Title: Process and apparatus for the production of sodium tripolyphosphate of the low temperature form
IPC: C01B25/41
Filed: 1962-12-19
Abstract: <PICT:1026675/C1/1> The low temperature form (form II) of sodium tripolyphosphate is produced in two treatment stages, viz.:-(i) solutions of mixed orthophosphate are dried to give an intermediate solid, and (ii) said solid is calcined with hot gases, said gases being furnace gases which are brought to a relative humidity of at least 16%, by being mixed with re-cycled process gases, before being utilized in the calcining stage.  Exhaust gases are removed from the recycling circuit through the calcining stage and used along with other furnace gases for heating the first or drying stage.  In the Figure, 1 represents the first treatment stage an atomizing drier fed by a solution of mixed orthophosphates which is evaporated with furnace gases from furnace 2 which gases are cooled to a desired temperature, e.g. 400 DEG  C., in a chamber 3 by being mixed with air and some of the exhaust gases from the calcining stage from pipe 15. The solid product from 1 is lead by line 7 into the plate oven 8 where it is calcined by gases from furnace 9 which are brought to a desired temperature and humidity, e.g. 500 DEG  C. and 20-25% relative humidity, in chamber 14 by being mixed, via line 13, with exhaust gases from oven 8 which have been cleaned in dust-separator 12.  Since the gases from line 13 may still have a temperature of, for example 400 DEG  C., only a small amount of furnace gas is required to produce the desired calcining temperature, but the quantity is also governed by the requirements of humidity, and mixtures containing at least three and preferably at least four to six times as much exhaust gas as furnace gas have been found suitable.  To provide a suitable calcining atmosphere on starting up the process, steam is introduced into the furnace gases from line 16. The exhaust gases from the first stage (evaporator 1) are cleaned in dust separator 4 and pumped via pump 5 to concentrator 6 where their waste heat is utilized.  One furnace may, if desired, replace the two furnaces 2 and 9, with appropriate division of the furnace gases to feed the two treatment stages.
