Title: An apparatus for ascertaining the amount of blood or haemoglobin present in a diluent liquid
IPC: A61M1/02
Filed: 1962-11-09
Abstract: 1,020,536. Photo-electric measuring apparatus; photometers. LAPS LJUNGBERG & CO. A.B. Nov. 9, 1962 [Nov. 30, 1961], No. 42375/62. Headings G1A and G1P. [Also in Divisions A5 and G2] In an apparatus for measuring the amount of blood or haemoglobin lost by a patient undergoing surgery, the swabs or other items containing the blood are placed in a known quantity of blood solvent liquid (for example an alkali) contained in the vessel 5 which liquid is then agitated and pumped to an analyser cell 14 where the amount of blood is photo-electrically determined. Before the blood soaked swabs are placed in the vessel 5 the liquid tight container 25 is filled with the pure solvent, the bladder 27 being collapsed. Some of this solvent through the valve 29 to fill the syringe 31. The solvent in the vessel 5 is then pumped through the pipe 9, the valve 10 and the pipe 11 back into the vessel 5. The orifice 12 on the pipe 11 causes pressure to rise on the pipe 26 thus dilating the bladder 27 which in turn ejects the pure solvent in the container 25 through the pipe 24, and the peripheral duct 42 in the valve 10 to fill the syringe 20. For calibration a light beam is passed through the transparent cell 14 (filled by means of a pipette with a sample of known dilution through the filter 16 to the photo-cell 17. A zero reading is obtained by replacing the known sample with pure solvent from the syringe 31 by rotating the valve 29, the piston 32, 33, 34 falling under its own weight. In use the swabs are placed in the vessel 5 and agitated by the stirrer 6. The valve 10 is rotated 90 degrees clockwise (Fig. 2 not shown) so that the peripheral duct 42 connects the pipes 9 and 13. The liquid to be tested is then pumped through the cell 14 and continuous readings taken on the meter 18. If the concentration of blood is large it is stated to be advantageous to stop the continuous flow, wash out the analyser cell 38 with pure liquid from the syringe 31 and to turn the valve 10 through an additional 90 degrees (Fig. 3 not shown) thus further diluting the solution remaining in the pipe 13 with the known quantity of solvent contained in the syringe 20.

Title: Starch fractionation
IPC: C08B30/20
Filed: 1960-12-12
Abstract: A method of fractionating starch comprises heating a mixture of starch and water containing more than 2,5% of starch to a temperature of 121 DEG -177 DEG C. under superatmospheric pressure for a period of up to 30 minutes so as to form a "fluid" solution without substantial degradation of the starch, cooling the solution to the atmospheric b.p., and then further cooling the solution to a temperature of 49 DEG C. at a viscosity of less than 1500 centipoises (adjusting the concentration, if necessary) in a period of at least 8 hours so as to "stabilize" the solution and form and grow a separable amylose-rich solid fraction suspended in a solution of amylopectin. The starch may be cold water swelling or cold water soluble, and may be slightly modified or dextrinized.  Corn, rice, wheat, tapioca, sago, sorghum, or potato starch may be treated.  Heating may be effected by steam under pressure as in Specification 895,215, or in an autoclave or coiled tube.  The heating is preferably effected rapidly with agitation. A heating temperature of 138 DEG -160 DEG C. is preferably maintained for a period of 0,5-15 minutes.  The solution is preferably cooled to the atmospheric b.p. by rapidly reducing the pressure.  The solution is preferably cooled slowly to the stabilizing temperature with the minimum of agitation.  The solution preferably contains 7-13% starch during cooling.  The solution may be seeded.  The amylose particles are preferably permitted to grow until at least 50% have a size of more than 20 microns.  A preservative, e.g. phenyl mercuric acetate, may be present during crystal growth.  The amylose particles may be separated by centrifugation or settling.  The separated amylose may be washed successively with water, methanol, and acetone, and dried at 110 DEG C.  Alternatively, after washing with water the separated amylose may be spray, roll, or vacuum dried.  The amylopectin solution fraction may be similarly dried, or used without drying. Examples are given.

Filed: 1967-09-25
Abstract: 1,141,139. Coiling wire. SCHLOEMANN A.G. 25 Sept., 1967 [29 Sept., 1966], No. 43445/67. Heading B3E. A method of depositing lengths of wire in non-concentric overlapping turns upon a continuously moving conveyer is characterized in that the turn layer, during the time interval between the laying of the last turn of one length of wire and the laying of the first turn of the next length, is retracted in a direction opposite to the direction of conveyance of the turns of wire, and during the depositing of the succeeding length of wire, is advanced in the direction of conveyance of the turns of wire. An apparatus for performing the method comprises a rotatable laying tube 2 which forms wire turns which are tripped by an edge 3 to fall on to the conveyer 4. The laying tube 2 is fed through a horizontal tube 7 which telescopes into a fixed tube 8. The tube 2 and its driving means 1 are mounted on a carriage 5 which is movable along rails 6 in a direction parallel to movement of the conveyer 4. A length of wire or rod from a rod-mill is laid in turns on the conveyer 4 and after the last turn of a length has been laid, the coiling head is quickly withdrawn from the dotted line position shown in Fig. 1 to the full line position. The first turn of the succeeding length of wire or rod is thus spaced from the last turn of the preceding length on the conveyer. During the laying of the turns resulting from the coiling of the wire, the head is slowly advanced to its original position, the conveyer speed being increased for the duration of the advance so that the turn spacing remains the same.
