Title: An improved web-feeding mechanism for bag-making and other machines
IPC: B65H20/04
Filed: 1928-08-08
Abstract: 318,725. Triggs, W. W., (Bates Valve Bag Corporation). Aug. 8, 1928. No Patent granted (Sealing fee not paid). Feeding webs.-A web-feeding mechanism for a bag-making or other machine comprises two pairs of continuously driven feed rollers, one roller of each pair being movable towards and away from the other roller but normally pressed into contact therewith, and a cam at each end of each movable roller operable to separate the rollers when desired for threading or adjusting the web, all the cams being connected to a lever for simultaneous operation. Each pair of rollers comprises a lower roller 6, Fig. 2, and an upper roller in the form of a number of discs 3 adjustably secured to a shaft 4, the bearings of which are normally pressed downwards by springs 15, Fig. 1, the pressure of which is adjustable by screws 16. Between the bearings of the rollers are arranged cams 10 secured to shafts 11, provided at their ends with hand levers 13 connected together by a link 14. Each pair of rollers is connected together by gears 18 and an idler gear 30, Fig. 1, connects the lower gears 18 together. The rollers are driven by a gear 18a on the shaft 7 of one of the rollers 6 connected through gears 23, 25 with a driving gear 28. The gear 23 is carried by links 24 mounted on the shaft 7 and the shaft 29 of the gear 25. The gear 28 also drives, through a gear 39, a pair of cutting rollers 38, 40 having cutting members carried by blocks 34, 41, moved outwardly at the correct time by rollers 37 operated by fixed cams 35. The length of the sheets is determined by the size of the gear 39, and to allow of different gears being employed, the gear 28 is carried by a bracket 26 adjustable about the shaft 29 and secured by a bolt 49. Beyond the cutting rollers are a pair of rollers 43, 44 having gripping blocks 45 which move at a slightly higher speed than the web so that a sudden pull is applied to the web at the moment is is cut so as to facilitate severance. The strong grip on the web by the second pair of feed rollers 6, 3 prevents this pull from being transmitted to the bag-making part of the machine. The feed discs 3 are adjusted so as to grip the tubular web 31 at parts clear of the folds. The feed rollers are mounted in a carriage 8 movable on guides 9 by screws 19 operated by gearing 20 and a hand wheel 22 so that small longitudinal adjustments of the web, particularly of a. previously printed web, can be effected.

Title: Improvements in the production of gaseous olefins by cracking hydrocarbons
Inventor: MARKERT FERDINAND
IPC: C10G9/00
Filed: 1958-07-23
Abstract: <PICT:0824913/IV (b)/1> In the preparation of olefines, particularly ethylene and propylene, by the high-temperature cracking of hydrocarbons the gaseous reaction stream is quenched by supplying laterally to the stream one or more compact jets of liquid in an amount sufficient to cool the gas by at least 100 DEG  C. and with a pressure head such that the liquid penetrates the gas and is disintegrated therein. Cracking may be effected in the presence of a fluidized solid, at 650-850 DEG  C., and 1-5 atmospheres, e.g. in reactor 1, to which oxygen is also supplied.  Solids are removed from the product stream by cyclone 2 from which the gaseous product leaves by pipe 4.  Jets of liquid, e.g. liquid reaction products boiling below 300 DEG  C., are injected into the gas from jets 6.  Preferably the product of (a) the ratio of the pressure head of liquid to that of the gas (measured at the point of entry to the cooling chamber) and (b) the ratio of the mean diameter of the liquid jet to that of the gas, should lie in the range 0.01 to 3.  Where several jets are used such products may differ for each jet and the jets may be in different planes.  The walls of the cooling chamber are preferably washed with the cooling liquid, e.g. from atomizer 7. Products leave by line 8.
