IPC: C07D303/04
Filed: 1994-09-21
Abstract: Disclosed are improved processes for the recovery of 3,4-epoxy-1-butene (EpB) from an epoxidation effluent comprising EpB, butadiene, oxygen and butane obtained by the selective epoxidation of butadiene with an oxygen-containing gas in the presence of a catalyst and an inert gas. EpB is separated from the effluent by means of an absorption process using liquid mixture of butadiene and butane as the absorbent material. The inclusion of butane in the epoxidation and recovery processes permits the use of lower pressures in the absorption of the EpB product.

Title: Fixed quality source coder
Inventor: HARRIS RICHARD W
IPC: H04N19/94
Filed: 1995-03-27
Abstract: A fixed quality source coder (20) receives and performs VQ on an input signal ID. The fixed quality source coder (20) includes an encoder (28) and may also include a decoder (34). The encoder may include a lossy codec (52) that receives and encodes the signal ID to provide encoded information (38) to a multiplexer (30) regarding the signal ID. The lossy codec (52) also decodes the encoded signal to produce a decoded signal IVQ-I (62). A summer (66) receives ID and IVQ-I and determines an error signal ER (70) where ER equals ID -IVQ-I. A threshold circuit (74) receives the signal ER and passes a truncated error signal ET'. The threshold level T may be set to ensure that the maximum error allowed in the encoder (28) is equal to a particular desired maximum error.

Title: Composite pressure sensitive hydrophilic adhesive and method of preparing the same
Inventor: SULC JIRI
IPC: C09J9/00
Filed: 1995-05-10
Abstract: Composite pressure sensitive hydrophilic adhesive, permeable for water vapor and losing its adhesiveness in contact with liquid water, particularly suitable for temporary glueing medical means to the body surface, comprising a gelled mixture of: (a) a water swellable, water insoluble polymer, soluble in polar water-miscible solvents boiling at atmospheric pressure at temperatures higher than 100 .degree.C as well as in their mixtures with minor amounts of water, (b) a hydrophilic water swellable polymer, insoluble in water as well as in polar water-miscible solvents boiling at atmospheric pressure at temperatures higher than 100 .degree.C, (c) a polar water-miscible innocuous solvent boiling at atmospheric pressure at temperatures higher than 100 .degree.C, if desired mixed with a minor amount of water. A feature of the composite pressure sensitive hydrophilic adhesive of the invention is that the separate polymers (a) and (b) are replaced by a non-crosslinked copolymer of hydrophilic and hydrophobic monomers, only partially soluble in the component (c) but swellable therein. The invention further comprises a method of preparing the composite pressure sensitive hydrophilic adhesive of the invention consisting in the intensive stirring of the dry powdered polymer (a), the water swellable, water insoluble polymer, soluble in polar water-miscible solvents boiling at atmospheric pressure at temperatures higher than 100 .degree.C as well as in their mixtures with minor amounts of water and polymer (b), the hydrophilic water swellable polymer, insoluble in water as well as in polar water-miscible solvents boiling at atmospheric pressure at temperatures higher than 100 .degree.C, in the (c) a polar water-miscible innocuous solvent boiling at atmospheric pressure at temperatures higher than 100 .degree.C, if desired mixed with a minor amount of water, spreading the paste thus obtained on a pad, and setting it to a gelled layer. The method of using the composite pressure sensitive hydrophilic adhesive consists in that the mixing of components is with advantage carried out at temperatures not exceeding 15 .degree.C and the thus received mass is afterwards spread to the surface of the medical means to be glued to the body surface, and subsequently the spread layer is left to set at temperatures in the range of from 15 .degree.C to about 100 .degree.C either by prolonged storage or by heating.

Title: Pharmaceutical nanosuspensions for medicament administration as systems with increased saturation solubility and speed of dissolution
Inventor: KRUSS BERND
IPC: C09K23/56
Filed: 1995-11-09
Abstract: Systems with a strongly increased saturation solubility (Cs) are obtained by preparing nanosuspensions of medicaments. The saturation solubility of medicaments with low bioavailability may thus be increased. This additional increase of the saturation solubility increases the speed of dissolution beyond what can be achieved by simply enlarging the surface of the medicament.  Extremely stable nanosuspensions are obtained by using very low surfactant and stabiliser concentrations. Surfactant-free nanosuspensions may be prepared.  Large-scale production of nanosuspensions with a very low content of micrometric particles is made possible by cavitation, with its accompanying advantages. The preparation of nanosuspensions by cavitation was thought to be impossible because the powdered medicament particles were expected to block the more or less 25 µm wide gap. Alternatively, the nanosuspensions may be prepared by shearing or impact in flow dispersion machines while respecting the above principles of optimum stabilisation or surfactant-free preparation.
