Abstract: S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.

Title: Method and apparatus for surface austempering of cast iron parts
Inventor: KOVACS BELA V
IPC: C21D5/00
Filed: 1990-12-03
Granted: 1999-01-19
Abstract: A method for producing a selectively surface hardened cast iron part includes uniformly heating the surface of the part by immersion into a molten metallic bath until a desired thickness of surface austenite is produced, and thereafter quenching the heated cast iron part in a liquid quenching bath which is maintained at a temperature of between about 450 to about 800°F for about 10 minutes to about 4 hours.  The resultant selectively surface hardened cast iron part is surface hardened with the bulk of the body of the part remaining untempered.  An apparatus for performing this process includes a molten metal bath chamber for containing the molten metal and a molten salt bath quenching chamber for quenching the cast iron parts with a conveyor means extending between the molten metal bath and the molten salt bath chambers.  A second conveyor means removes the parts from the molten salt bath chamber.

Abstract: A communications network is implemented utilizing a transmission medium and a plurality of Network Interface Units passively coupled thereto. Communications among a first set of Network Interface Units is implemented on a predetermined channel in a first portion of the transmission medium. Simultaneous communications among a second set of Network Interface Units is implemented using the same predetermined channel in a second portion of the transmission medium. Interference between communications in the first and second portions does not occur because the passive couplers disposed between the portions attenuate the signal from each portion to a value less than a predetermined Network Interface Unit sensitivity level before the signal reaches the other portion.

Abstract: A manually operable device for detecting wood pole decay and a method of using the same are disclosed. A gamma ray emitter is provided with guide means enabling it to be piloted longitudinally along the wooden pole so that gamma rays from the emitter pass diametrically through the wooden pole along a longitudinal axis of the pole. The attenuation of the gamma rays are continuously recorded along the longitudinal axis, and a permanent record of the variation in gamma ray attenuation is made, from which it can be determined whether the pole is healthy or decayed, and if decayed, the location of the decay along the pole. In order to facilitate locating decay in the pole, the guide means includes an odometer programmed to provide an electrical pulse every 15cm which is recorded with the data of gamma ray attenuation. Once data on gamma ray attenuation has been recorded along one longitudinal axis of the pole, the device may be used on a longitudinal axis at 90 order to pinpoint the latitude and extent of decay points in the wooden pole.

Abstract: IMPROVED DATA COMPRESSION SYSTEM AND METHOD                        ABSTRACT Image data compression is implemented by partitioning an image into rela-tively small blocks of pixels, matching each block to an orthogonal icon, and extract-ing attributes associated with the icon. A table of these orthogonal icons and at-tributes represents a data compressed image. Each block is processed separately from all other blocks. Orthogonal processing is used to preserve orthogonal features while attenuating non-orthogonal features. An optimum set of orthogonal icons and an optimum set of attributes for each icon further improves data compression and fi-delity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a rib-bon icon, a corner icon, and a spot icon. An optimal set of attributes includes aver-age intensities, intensity transition position and separation, and angle of the principal axes.

Abstract: An insulating unit is disclosed having a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. Also disclosed is a spacer for use in insulating units including a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer. The unit has a long diffusion path to increase the time period in which insulating glass e.g. Argon gas may be retained in the compartment. The increased RES-value provides a unit that has a low thermal conducting edge. In this manner heat loss through the marginal edge of the unit is reduced.
