Abstract: 991,193. Orthopaedic traction apparatus. A. M. GOODMAN. June 14, 1962 [July 18, 1961], No. 22928/62. Heading A5R. [Also in Division G1] An orthopaedic traction device comprises one or more elasticized webbing members with a graduated empirical poundage scale marked thereon, each member having means for connecting it between a rigid support and a traction halter, corset or cuff. A head halter is connected at each end through an elasticized webbing strap 2 having the scale marked thereon, to an adjustable non-elastic webbing loop 5 to a rigid support, e.g. a door frame, bed or chair. Alternatively, an adjustable elasticized webbing loop (Fig. 2, not shown) connects each end of the halter with the support. A pointer 8 fixed to one end of the elasticized webbing strap or loop indicates the tension applied on the scale 9.

Abstract: In modifying and simultaneously gelatinizing an aqueous suspension of starch, e.g. for sizing textiles and paper, the suspension containing a soluble zinc salt furnishing divalent zinc cations, e.g. the chloride, acetate or sulphate, is heated under superatmospheric pressure to a temperature above 250 DEG F.  Between 0,25 and 1,5 g. of zinc in the form of the salt may be used for each pound of starch present.  An aqueous slurry containing about 1 pound of starch and between 0,5 and 3 g. of zinc chloride per gallon may be pumped through a heat-exchanger or cooker, constructed as described in Specification 649,324 and brought to a temperature between 250 DEG and 310 DEG F., the pressure on the slurry being in excess of the vapour pressure of water at this temperature.  The slurry may be kept at the elevated temperature and pressure for at least two minutes and the pressure may then be released to flash-cool the slurry to a temperature below its atmospheric boiling point.  The slurry may be heated to a temperature of about 290 DEG F. and held at a temperature between 280 DEG  and 290 DEG F. for an optimum period of 4 minutes.

Abstract: <PICT:1045733/C1/1> <PICT:1045733/C1/2> Curved glass sheets are toughened by subjecting both faces of the heated sheet to the action of chilling fluid jets which move with a periodic motion which is so arranged that the pressures on both sides of the sheet remain in balance and thus prevent the sheet from moving during quenching. Preferably the quenching jets are moved in a direction parallel to the central linear portion of a glass sheet having at least one curved end, the movement being such that as one set of quenching jets approaches the curved end so does the other.  As shown a curved glass sheet is suspended between a pair of quenching frames 10, 11 mounted in carriages 16, 17, the carriages being horizontally reciprocated in frames 18, 19 under the action of eccentrics 27, 28 and the latter frames being mounted for vertical movement in guides 20, 21 under the action of cams 22, 23.

Abstract: 510,761. Artificial filaments etc.; dyeing. BRITISH CELANESE, Ltd. Aug. 16, 1938, No. 24092. Convention date, Aug. 25, 1937. [Classes 2(ii) and 15(ii)] Artificial filaments, straws, ribbons or the like, particularly those having a basis of a cellulose ester or a cellulose ether, have a neutral grey shade or a black colouration due to colloidal graphite being distributed throughout their substance. The graphite may be incorporated in a spinning solution, and after being spun into a setting medium to produce filaments of a neutral grey shade, the materials are coloured by a dyestuff having direct affinity therefor ; by this method only a small quantity of the dyestuff is used. The spinning solution is prepared by shaking together a thick paste containing the colloidal graphite and the ingredients of the spinning solution, with a quantity of the solvent employed in the solution, the weight of the solvent being from eight to twelve times that of the paste. By varying the quantity of graphite employed from 0.02 per cent. to 3.0 per cent. of the weight of materials produced, the depth of shade can be varied from pale neutral grey to jet black.
