Abstract: ABSTRACT OF THE DISCLOSURE     A muffler for attenuating core and turbine noise generated by a gas turbine engine is in the form of a housing of rectangular section spaced from and surrounding a duct defining a flow passage for the exhaust gases from the engine.  The enclosed space around the duct and within the housing is divided into a number of acoustic attenuators with opposite sides of the duct each containing a reactive attenuator chamber and a resonant attenuator chamber within the first chamber at the downstream end.  Opposite sides of the duct are perforated to provide acoustic communication between the passage on the one hand, and the downstream end of the reactive duct and the whole length of the resonant duct on the other hand.  The reactive duct is a closed cavity whose dimensions and shape determine its acoustic characteristics while the resonant duct is in the form of a number of individual attenuating cells.  The four attenuators are designed to attenuate sound primarily at different frequencies so that frequencies over a fairly wide range can be attenuated by a single muffler of compact construction.  The reactive attenuators are designed to attenuate engine core noise while the resonant attenuators are designed to attenuate turbine noise.

Abstract: ABSTRACT OF THE DISCLOSURE         An ultrasonic imaging system and method are disclosed which include a transducer (10) for pulse insonification (16) of an object (14).  Reflecting means (29) containing scatterers is acoustically coupled to object (14) opposite transducer (10).  Echo signals received from within reflecting means (29) are converted to electrical signals at the transducer (10), which electrical signals are supplied to a signal processor (30) for processing the same.  Echo signals obtained from a range zone (Z) within reflecting means (29) are integrated by integrator (42).  The amplitude of echo signals from the range zone (Z) is strongly dependent upon attenuation at the focal point (F) whereby the integrator (42) output (60) also is strongly dependent upon attenuation at the focal point (F).  The integrator (42) output (60) is supplied to a display (48) for use in establishing one pixel thereof.  A C-scan display is provided by scanning the focal point (F) in a focal plane (22) substantially normal to the beam axis (20).

Abstract: ABSTRACT                 DRUG PARTICLES HAVING CONSTANT RELEASE         AND IMMEDIATE RELEASE       Drug particles are disclosed which reduce the variation in dissolution rate with time frequently found with sustained-release dosage forms. Additionally the particles give very rapid absorption of the drug by the body. This is achieved by coating the drug particle with a first coating of an enteric material, a second coating of a material which is insoluble at any pH and acts as a diffusion barrier for the drug active and a final, third, coating of a mixture of the drug and hydrophilic excipients.

Title: Conversion of beta-aescin into alpha-aescin
Inventor: WAGNER JOSEF DR
IPC: D03C1/06
Filed: 1967-03-06
Abstract: Prepn. of alpha-aescin by maintaining beta-aescin (in the form of the free acid) in an aqueous soln. at pH 4.5-7.5 (pref. pH 6.0-6.9) at a relatively low temp. (e.g. 10-100 deg.C, pref. 60-90 deg.). By maintaining a pH of 4.5-7.5, the scission of acyl groups and conversion into aescinol are substantially avoided. The alpha-aescin obtained has a low haemolytic index (of the order of 1:15,000 to 1:22,000) and is soluble in water, whereas beta-aescin is relatively difficulty soluble in water. 1-10% aq. solutions of alpha-aescin can be heat sterilised without increasing haemolytic activity.

Abstract: A gas stream including the vapor of a solvent is passed through conduit (28) into a reflux heat exchange (40) so as to effect condensation of substantially all the solvent vapor. Cryogenic liquid is introduced through line (70) into condensate of the solvent vapor collecting in bottom section (42) of the condenser to cool the condensate and to stir or agitate it (such agitation preventing local freezing). Chilled solvent condensate is withdrawn from the bottom section (42) and is returned to overhead section (43) of the heat exchanger (40) via a conduit (66) and thus serves as reflux. A further portion of the chilled solvent may be returned to the condensate so as to augment the stirring or agitation of the liquid. Condensate may be withdrawn through the conduit (50) and passed to storage. 
<??>The gas stream may typically be passed first through a water-cooled heat exchanger (13) and then through a heat exchanger (23), cooled by uncondensed gas from the reflux heat exchanger (40), before entering the heat exchanger (40) so as to condense some of the solvent vapor it contains upstream of the heat exchanger (40).
