Abstract: 1327743 Knitting machines NORTH AMERICAN ROCKWELL CORP 11 Jan 1971 [1 April 1970] 1242/71 Heading D1C In a rotary cylinder circular knitting machine, pattern means acting on the pattern butts of jacks 11 comprises selector levers 15 moved by the trick butt pattern of a second trick drum 40 individually into active positions in which they are acted on by the trick butt pattern of a first trick drum 26 which is indexed round in a plurality of indexing movements while drum 40 only moves in one of these movements. A pivoted lever 15 corresponds to each level of pattern butts on rocking jacks 11, and each has nose portions 25, 37 which engage butts on drums 26, 40 mounted on pin 27 and stud 36 respectively. Drum 26 is rotated by ratchet 30 and pawl 31 pivoted to a lever 35 to which a pawl 42 is also pivoted which with ratchet 41 rotates drum 40. Springs 47, 50 bias the pawls into engagement with their ratchets. A butt pattern at one level on drum 40 acts on a lever 51 with a downwardly extending rod 53 for engagement with pawl 31 to hold it inactive. A lever 57 actuated by a Bowden wire 63 connected to a lever engaging the main cam drum has a nose portion 55 which engages a part 52 of pawl 42 to move it between normal inactive position as determined by adjustable stop screw 80 and active position. Pawl 42 is also controlled by a finger 82 on arm 57 which engages a butt pattern at one level on drum 40. Lever 35 is connected by link 85 to a lever 87 connected by an adjustable link 96 to one end of a lever 100 whose other end carries a follower 105 which engages a cam 106 on the drive shaft 107 which rotates once per revolution of the cylinder. The lobes 110 of cam 106 cause lever 35 to move pawls 31, 42 to the same extent in an indexing direction each rotation of shaft 107 while portions 111, 112 of different depth move the pawls to different extents in the resetting direction. Drums 26, 40 have the same number of tricks. Hence pawl 31 indexes ratchet 30 and trick drum 26 a single tooth following resetting movements thereof by both the low portion of cam 106 and pawl 42 indexes ratchet 41 and drum 40 a single tooth following a resetting movement thereof by only one of the low portions.

Title: Improvements in or relating to the sulphation of propylene
IPC: C07C303/24
Filed: 1942-02-06
Abstract: 555,142. Sulphation of propylene. DISTILLERS CO., Ltd., WOOD, W. L., SALT, F. E., and STUART, I. B. Feb. 6, 1942, No. 1601. [Class 2 (iii)] In the sulphation of propylene, up to the formation of the monoester, the acid and gaseous propylene are passed in the same direction through a reactor having a reaction zone long in relation to its cross sectional area at a velocity greater than the critical velocity. The latter is defined as that velocity above which there is a sudden drop in back pressure, due to the liquid acid being forced to spread as a thin film over the whole inner surface of the tubular reactor. The reactor may consist of horizontal or vertical coils or straight tubes coupled by return bends. The acid should preferably flow upwards when the coils are vertical but if jacketted tubes are used they should be inclined to the horizontal. The tubes may be air or water cooled or the reactor may consist of tubes of gradually increasing diameter, the heat-development being greatest at, the inlet. Alternatively the sulphation may be effected in a multi-stage unit comprising a number of reactors in each of which the reactants flow in the same direction, but in the unit as a whole the propylene and sulphuric acid flow in countercurrent, the propylene being treated in the early stages with partly esterified acid withdrawn from a later stage and only in the last stage with fresh acid. In examples: (1) gas containing 93 per cent. propylene is passed, with sulphuric acid into a reactor comprising 920 feet of half-inch bore tubing arranged in ten coils ; the resulting mixture of mono and di esters is hydrolized to isopropanol : (2) propylene is similarly absorbed in acid in 900 feet of one-and-a-half-inch bore tubing arranged in 20-foot lengths coupled by return bends.
