IPC: C12P19/14
Filed: 1948-08-27
Abstract: Laundry starch is prepared by subjecting a slurry of starch to simultaneous gelatinization in hot water and mechanical disruption, followed by treatment with an enzyme capable of hydrolyzing starch at high temperatures, and then inactivating the enzyme and drying the product, whereby a material having not more than 12 per cent of linear polymer with an average degree of polymerization not exceeding 250, a branched polymer with an average degree of polymerization not less than 200, and less than 1.5 per cent of reducing sugars is obtained.  A starch slurry of approximately 17 DEG  B<\>e to which is added 0.1 per cent of calcium chloride has its pH adjusted to approximately 6.5 by the addition of soda ash and there is then added 3.0-7.5 per cent of boric acid and 0.4 per cent of a starch-liquefying heat-resistant amylase, e.g. a preparation of thermophilic bacteria such as bacillus mesentericus or bacillus subtilis.  The slurry is delivered to a heat-exchanger of the type consisting of a jacketed heat-transfer tube in which is mounted a rotator leaving a relatively narrow annular space and carrying scraper blades whereby the slurry is rapidly heated and agitated. The slurry is heated to a temperature of 170-196 DEG  F., preferably 190-192 DEG  F. and is kept at that temperature for 29-38 seconds. The slurry is then passed to a conversion coil wherein it is maintained at the requisite temperature for 20-30 minutes, the flow being at the rate of about 3 feet per minute and there being provision for tapping the coil to obtain material treated for different periods. The enzyme is then deactivated by heating to about 230-290 DEG  F. and the paste is subsequently dried in a roll dryer. If the paste is not to be dried immediately after deactivation of the enzyme, a stabilizer such as ammonium thiocyanate or dicyandiamide is added.

Abstract: 155,047. Haddan, A. J. H., (Sievert, H. A..). Sept. 19, 1919. Riding-saddles.-A saddle is arranged for automatic adjustment to the back of an animal, and for adjustment of the seat to suit different riders. The side-bars 10 are formed of pressed metal 16, convex on the inner side and covered with leather or the like 17. The concave side is filled with padding 15 held in place by surfacing 17<a>. The surfacings 17, 17<a> on the under and upper sides may be extended to form flaps 22, 21 between which the girth 23 i.s held. The side-bars are pivotally connected together through the pommel arch 11 and cantle arch 12. The cantle arch 12 is formed of a steel rod bent as shown, and its two ends 12<a>, Fig. 5, are bent at rightangles and passed through the rear walls 25 of the cantle 14, and are secured by nuts 26. The opening 28 in each wall 25 for the passage of the arch is made sufficiently large to permit the various relative movements. These points of connexion are somewhat removed from the central longitudinal vertical plane of the saddle and from the inner edges of the side-bars. The pommel arch 11, Fig. 2, is made of leather-covered metal bent and ribbed lengthways as shown, and provided with edge flanges 33. The pommel pivots are removed from the inner edges of the side-bars rather more than the cantle pivots, and they incline rearwardly and upwardly along lines which, if produced, would pass through the cantle pivots. Each pivot pin 32 passes through the front flange 33 of the arch and through two ears 34, Fig. 3, which are firmly connected to the metal body and project into the interior of the arch. The pin also engages with holes in a series of lugs formed on a bracket 35<a> attached to the side-bar 10. In this way the pommel may be adjusted forwardly or rearwardly to vary the length of the seat 13, Fig. 2, on the upper part of the side-bars 10 between the cantle and pommel. The front end 32a of the pivot pin is bent on itself, split, and spread, and the split end is passed through the flange 33 to prevent the pin from working out. The stirrups 40 are hung on straps 41 attached to the pommel arch, and may be adjusted slightly without ad. justing the pommel. The surcingle, formed by the upper part of the girth 23, is passed over the space 19 between the side-bars, and may be provided with a supporting arch made of spring metal and resting, at its ends on the side-bars. The rear wall of the cantle 14 may be left open, and the arch formed of two members mounted on the side walls 27 and pivoted together midway between the side-bars.
