Abstract: 1523451 Stranding machines FUJI ELECTRIC WIRE CO Ltd 6 Aug 1975 32941/75 Heading D1T A stranding machine comprising a plurality of co-axial supply drums 1, Fig. 1, each mounted on a shaft 17 includes a main shaft 4 that is parallel with the shafts 17, means 50, 52 for driving each drum 1 from the main shaft 4, and an arm 29 for each drum 1, clutch means operative to drivably interconnect each drum to its associated arm member in one direction only, each arm 29 rotating around its drum to draw off the material therefrom and guide it into a hollow portion of the shaft 17, the resulting plurality of filamentary materials that emerge from the last shaft 17 being twisted together and then wound up onto a drum. In Fig. 2 there is a one way clutch 35 between the drum 1 and the arm 29 to ensure that when the machine stops the drum 1 does not overun the arm 29. The arm 29 is rigid with a shaft 26 driven by a belt 27 coupled to the shaft 4. The drum 1 is driven by the shaft 4 via a magnetic clutch 52 energized by an electric current. If the magnetic clutch 52 has a weak magnetization a small driving force is applied by the clutch 52 to the drum 1 and this gives rise to a weak tension in the material 2 being unwound. If on the other hand, the clutch 52 is energized to give a strong magnetization an enhanced driving force is applied to the drum 1 and this gives rise to a strong tension in the material 2. To remove an empty drum 1 a pin 43 is withdrawn from a locking relationship between a handle 41 and plate 44. The handle 41 can then be turned relatively to the plate 44 and this causes a shaft 25 to move axially away from the drum 1.

Title: Improvements relating to the removal of carbonic acid from gas by washing
IPC: C10K1/12
Filed: 1937-12-02
Abstract: <PICT:0496431/III/1> A washing liquid used for removing carbon dioxide from gases is regenerated by passing the pre-heated liquid into a two-part trickle tower between the upper and lower parts thereof, the gaseous component flowing upwards through the upper part and the liquid component flowing downwards through the lower part; the gaseous component being washed by water flowing down through the upper part and the liquid component being aerated by air flowing up through both parts; and the washing from the upper part being added to the regenerated washing liquid, thus compensating for its loss of water.  Gases containing carbon dioxide are washed in packed towers 1 by a counterflow of potassium carbonate solution which enters the tower at about 60-70 DEG  C.  The bicarbonate containing washing solution flows to a storage tank 2 and is pumped through a heat exchanger 4 to a heater 5 in which it is heated to 95-105 DEG  C.  At this temperature the bicarbonate solution yields carbon dioxide.  The residual solution still containing some carbon dioxide is then passed into the two-part packed tower 6 between the upper and lower parts. Air is blown into the lower part 17 from below by an air pump 7, whilst water is sprayed from above into the upper part 18.  The two parts 17 and 18 are separated by a partition 11 having through passages 12 covered by hoods 13.  This allows the upward passage of gases but prevents the downward flowing liquid from passing from the part 18 into the part 17.  This liquid collects on the partition 11 and is delivered by a pipe 14 to the bottom of the lower part 17 where it mixes with the washing solution.  The mixture passes through the pre-heater 4 to a receptacle 8 from which it is pumped to the towers 1.  Alternatively, the liquid collecting on the partition 11 may be led by a pump 15 directly to the receptacle 8.
