Abstract: Abstract In the dual burner of a gas turbine or a hot gas generating system, the swirler (1) is formed from at least two doubly curved sheets (4, 5) subject to tangen-tial air inlet (7).  These sheets (4, 5) are folded along diagonals (10a, 10b) running conically outwards in the outlet flow direction.  One curved fold face forms an inner cone (4b, 5b) expanding in the outlet flow direction while the other curved fold faced forms an outer cone (4a, 5a) which contracts in the outlet flow direction.  The inner cones (4b, 5b) each carry at their ends a fuel main (8) whose fuel nozzles (9) are directed towards the inner zone of the swirler (1).  The liquid fuel (2a, 2b) is directed onto the outer cone (4a, 5a), the oil film (6) forming there being "rolled in" by the air (7) flowing into the outer cone (4a, 5a).

The tea concentrate comprises from about 0.4 to about 8% by weight tea solids, an edible gum selected from xanthan gum, cellulose gums, locust bean gum, guar gum and mixtures thereof in specified amounts, and optionally a solubilizer selected from the sugars, the polyols and mixtures thereof in specified amounts. The tea concentrate has a pH of about 4.6 or less at 20°C and is therefore stable against the growth of most microbial pathogens without the use of preservatives. Tea beverages prepared from this tea concentrate also have low astringency, fresh brewed tea flavor, and an enhanced mouthfeel.

Abstract: An electrical insulating oil composition which is excellent in low temperature characteristics and suitable for use in impregnating capacitors, and comprises (a) m-ethylbiphenyl, (b) p-ethylbiphenyl, (c) m-isopropyl-biphenyl and (d) p-isopropylbiphenyl, and is characterized in that the total amount of the ethylbiphenyls is not less than 40% by weight and the proportion of solid phase in the composition at a temperature of -40°C is not more than 45% by weight, the solid quantity of each component being calculated according to the following equation of solid-liquid equilibrium:       wherein Xi is the equilibrium mole fraction of a component i in the liquid phase of the composition, .DELTA.H? is the heat of fusion (cal.mol-1) of the component i, T? is the melting point (K) of the component i, T is the temperature (K) of the system, and R is the gas constant (cal.mol-1.K-1).

Abstract: GLUCOSE FREE MEDIA FOR STORING BLOOD PLATELETS     Abstract Novel methods and storage media for storing platelets in a viable condition for at least five days are disclosed.          The disclosed methods comprise the step of providing a platelet rich suspension of platelets and blood plasma extracting supernatant plasma from that suspension to leave between about 1 to 15 mls of plasma per unit of blood platelets with those platelets to produce a concentrated platelet button; adding 40 to 70 ml/unit of a glucose free aqueous solution to said concentrated platelet buttons agitating the resultant solution to resuspend the platelets to provide a synthetic suspension of those platelets; and storing that synthetic suspension in an oxygen permeable container at about 22°C until needed for use.  Two preferred glucose free aqueous platelet storage media are disclosed which generally comprise sodium citrate, sodium chloride, potassium chloride, and either sodium phosphate or calcium chloride, but not both.  The subject media also optionally comprise magnesium sulfate.  Results comparable to storing blood platelets in plasma are disclosed using media which free plasma for other uses and which may reduce the risk of disease transmission from platelet infusion.
