Patent JP-H0425941-B2 (JP)
IPC: C07C69/96
Filed: 1984-08-24
Abstract: Process for the preparation of  alpha -chlorinated chloroformates with the formula   <IMAGE>   where R is H, an aliphatic or aromatic hydrocarbon radical or heterocyclic radical, substituted or non-substituted and n an integer. The process consists of reacting ClCOOCCl3 or Cl3COCOOCCl3 with an aldehyde with formula R-(CHO)n in the presence of a compound, which in the medium releases a pair of ions, the anion of which being a halide which can attack the aldehyde function, because of the weak attractive power of the cation of this compound.
Patent JP-H0413127-B2 (JP)
IPC: D21F3/02
Filed: 1987-08-04
Abstract: The invention relates to a method of the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines. With known manufacturing methods for such press bands, the provision of a structured surface for liquid discharge on the outer surface of the press band, which faces the fibrous web or the felts, is achieved either by reversing the press band after removal from the casting mould so that the structured surface becomes the outer surface of the band while the smooth surface forms the inside thereof, or by grinding drainage ducts into the outer surface of the press band. But especially in the case of small band diameters, reversing of such cast press bands causes serious problems and entails considerable expenditure, wherein the risk of damage to the band cannot be excluded and grinding of the drainage ducts is just as expensive. To simplify the manufacturing process and to eliminate reversing of the press band after removal thereof from the casting mould, the inner wall of the centrifugal tube is provided with cavities and/or depressions which upon casting of the free-flowing mixture are filled therewith to form raised surface portions on the outer surface of the finished press band, so that in a subsequent pressing operation liquid to be discharged may be drained between said raised portions, and the completely cast press band is ground to finished size on the inside thereof.

Abstract: In synchronizing mechanisms for clutches having arranged between the clutch body (10) and the axially displaceable gear shift sleeve, each of which are provided with a toothing, a synchronizing ring (14) with teeth (33) having inclined check faces (35, 36) provided on their ends facing the gear shift sleeve, which check faces (35, 36) coact with matching check faces (37, 38) on the ends of the teeth (34) of the gear shift sleeve, it is provided for the purpose of reducing cold scratch that the check faces on the ends of the teeth (34) of the gear shift sleeve are designed asymmetrically in such a manner that the check faces (37) leading in the sense of rotation (28) have a greater axial extension than the check faces (38) trailing in the sense of rotation. This ensures that accelerated synchronization occurs after attainment of synchronous speeds when due to the existence of high braking moments in the transmission, in particular due to the high viscosity of cold transmission oil, the transmission is braked too rapidly in a manner interfering with the synchronization process. A similar effect can be achieved also with the aid of pressure elements which guarantee that the synchronizing ring is rotated radpily into the locked position opposite the sense of rotation. Particularly favorable effects are obtained when the inclined faces described before are employed in combination with such pressure elements.

Abstract: In order to prepare crystalline sodium disilicates having a sheet structure, a molar ratio of SiO2 to Na2O of (from 1.9 to 2.1):1 and a water content of less than 0.3% by weight, a water glass solution is first obtained by reacting sand with aqueous sodium hydroxide in a molar ratio SiO2 to Na2O of (from 2.0 to 2.3):1 at temperatures of from 180 to 240 DEG C and pressures of from 10 to 30 bar. This water glass solution having a solids content of at least 20% by weight is treated in a spray dryer with hot air of from 200 to 300 DEG C to form a powdered amorphous sodium disilicate having a water content (determined as loss at red heat at 700 DEG C) of from 15 to 23% by weight and a bulk weight of at least 300 g/l. The spray-dried powdered amorphous sodium disilicate is pre-ground. The pre-ground sodium disilicate is introduced into a rotary kiln which is equipped with devices for moving solids, is heated externally via its wall and in its interior has a plurality of different temperature zones, the sodium disilicate being treated therein at temperatures of from 400 to 800 DEG C for from 1 to 60 minutes to form crystalline sodium disilicate.

Abstract: Method using oxygen removal for extending the useful shelf-life of refrigerated red blood cells. A cost-effective, 4 DEG  C. storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. Preservation of adenosine triphosphate levels and reduction in hemolysis and in membrane vesicle production of red blood cells stored at 4 DEG  C. for prolonged periods of time is achieved by removing oxygen therefrom at the time of storage; in particular, by flushing with an inert gas. Adenosine triphosphate levels of the stored red blood cells are boosted in some samples by addition of ammonium phosphate.
