Abstract: 1339175 Amylose films K HAYASHIBARA 19 Jan 1971 [26 Jan 1970] 2661/71 Heading B5B Amylose films are prepared by a process which comprises forming films by conventional methods from starch material containing a mixture of starch having an amylose content of greater than 50% by weight and a hydrolyzate obtained by the hydrolysis of a common starch with α-1,6, glucosidase. Preferably the starch is an amylomaize starch or amylose separated from common starch and the starch hydrolyzate comprises amylose having a degree of polymerization of less than 50 and is obtained by fractionation of the product of hydrolysis of a waxy starch. Examples 1-3 relate to the enzymatic treatment of amylomaize starch to produce hydrolyzates containing a high proportion of short chain amylose (D.P. less than 50) and in Examples 4-8 these hydrolyzates'are combined with amylomaize starch or commercial amylose and formed into films. The filmforming procedure comprises dissolving the starch mixture in an aqueous alkali solution containing NaOH, Na 2 SO 3  and glycerin, filtering, degassing, casting the resultant solution on to a glass plate and coagulating the cast film by immersion in an aqueous bath comtaining H 2 SO 4  and Na 2 SO 4 . After washing with water the films are plasticized by immersion in glycerin solutions and are then dried at 30‹ C.

The copolymer of acrylonitrile may have a relative viscosity (# rel.) within the range 1À7 to 2À7 as measured at 20‹ C. in dimethyl formamide at a concentration of 0À5 g./100 ml. The sulphobetaine content of the copolymer component of the conjugate filaments may be 5 to 10% by weight. The conjugate filaments produced may be stretched, e.g. at a stretch ratio of 4 : 1, and at a temperature of about 100‹ C. They may then be heat-set at a temperature within the range of 70‹ to 150‹ C. The unsaturated hydrazide sulphobetaines used in the examples are In the example the copolymer of which the components of the conjugate filaments are composed are separately dissolved in dimethyl formamide and the resulting spinning solutions simultaneously extruded through each extrusion orifice of a spinneret into a gaseous evaporative medium as in normal dry spinning.

Abstract: 746,978. Rotary pumps. SMOOT, L. P., and MOREHOUSE, G. H.. [trading as MOREHOUSE INDUSTRIES]. Feb. 2, 1954 [May 25, 1953], No. 3045/54. Class 110(2) [Also in Group XXIX] An apparatus for removing air bubbles from a substance such as grease comprises a pump, through which the substance may be continuously circulated, or, under valve control, the pump delivery may be discharged, e.g. to containers. The continuous circulation may be carried out while a filled container is being replaced by an empty one at an outlet 39, to prevent the stopping of the pump. As shown in Fig. 1, a pump 5 with gears 11 sucks grease containing air or gas bubbles from a port 19 to which the grease is supplied by way of a pipe 40 under control of a restricting valve 41, Fig. 2 (not shown). Due to the partial vacuum applied to the grease, as it leaves the valve 41, air bubbles expand and burst, and further de-aeration occurs when the grease is passed through a screen 35. The grease is discharged through a passage 36 in a rotary valve 18. The valve may be rotated in bearings 24, through a handle 31, see Fig. 4, to shut off the delivery port 36, the grease then circulating through the pump. To prevent locking of the pump, during the rotation of the valve 18, recesses 47 are formed in the valve body so that communication between ports 21, 22 will not be broken until the upper end of the passage 32 has partially overlapped the port 21.
