Title: Regenerated cellulose fibers and process for welding same
Inventor: ANDERER JOSEPH H
IPC: D21H13/08
Filed: 1959-07-20
Abstract: Regenerated cellulose fibres having an average wall thickness not exceeding about 3 microns, a tensile strength not exceeding about two grams per square micron of cross-sectional area and a water-retention of at least about double that of solid fibres of like mass and composition, and further characterized by being at least partially collapsed and at least partially ruptured along their lengths, are produced by dispersing by vigorous agitation in viscose, containing a small proportion of a surface active agent, a gas in the form of bubbles whose average diameter at atmospheric pressure does not exceed about half the diameter of the spinneret orifices, and extruding the viscose into an acid spinning bath to form continuous filaments.  The proportion of gas in the viscose may be one c.c. of gas measured at atmospheric pressure to about 0,1 to 5 grams of cellulose in the viscose.  The surface active agent may be sodium oleate, sodium lauryl sulphate, Turkey red oil or secondary amide derivatives of higher fatty acids and may be present in the viscose in proportions of about 0,1 to 5%, based on the weight of the cellulose.  In an example, nitrogen at a gauge pressure of 50 p.s.i. and sodium lauryl sulphate are simultaneously pumped into viscose in a closed mixing chamber, the proportion of sulphate based upon the cellulose in the viscose being 1% and the nitrogen : cellulose ratio being 1 c.c. of gas per 5 grams of cellulose.  The viscose is then passed through a second closed mixing device and extruded through a spinneret into a coagulating and regenerating bath containing 9,2% of sulphuric acid, 8% of zinc sulphate and 18% of sodium sulphate and maintained at about 60 DEG C., to produce a tow of 1,5 denier filaments.  The filaments are then stretched 85% in 2,5% aqueous sulphuric acid maintained at about 95 DEG C.  Regenerated cellulose fibres produced according to the invention may be used to form water-laid sheet (see Group VIII).  Specification 596,772 is referred to.

Moist, finely ground coal having a maximum granule size of 1 to 3 mm. and a moisture content of less than 11 %, is formed in a briquetting press, Fig. 4, into briquettes having a weight of more than 35 grams and united by a web of at least 2 mm. thickness, to form a string of briquettes which, after emergence from the press, breaks up irregularly, the briquettes and web not breaking up much more before they enter a coke oven. As shown the coal from bunker 1, Fig. 2, traverses a chain conveyer 2, discharge pipe 3 and hopper 4, having a vibration device 6, to the briquetting press 5, which consists of a pair of rollers 20 having mould cavities 21, the shortest distance between the rollers being 10 to 15 mm. The string of coal 22 emerging from the press breaks up irregularly and slides down the shaking conveyer 7 to buckets 8 of a conveyer 9. In a modification a vibrating spiral conveyer replaces the bucket conveyer. The briquettes reach the bunker 10 of a charging car. On charging the coke oven 15, Fig. 3, the closing member 12 is opened whereupon the briquettes pass through a funnel 16, in a jacket 13 surrounding the member 12, and enter the oven 15 through the hole 14. Air and gases evolved during charging pass through the annular passage between funnel 16 and jacket 13 to a pipe 17 leading to the atmosphere.

Abstract: 190,801. Boxell, S. Sept. 29, 1921. Heating buildings, steam-traps.-In order to drain away the water of condensation from a steam-heating system, the system is connected bv a pipe F with a water-cooled tank A in which a vacuum is intermittently and automatically formed by the condensation of steam admitted through a pipe C, the inflow of steam being regulated by a floatcontrolled valve E and the flow of condensed water through the outlet G being controlled by a second float-controlled valve I. In action, when sufficient water of condensation has collected in the tank A, the valve E closes the steam admission pipe, the lower end of an air release pipe M is sealed, and the steam above the water condenses forming a vacuum and withdrawing further water of condensation from the system. This causes the float H to rise and by means of an arm J having a lost motion connection with a link K the valve I is opened and remains open until a definite amount of the condensed water has been discharged, when the series of operations is repeated.
