Abstract: A process for the manufacture of vancomycin which does not require preparation of a phosphate intermediate. The process consists of passing a vancomycin broth through a suitable adsorbent, followed by passing the vancomycin through a second adsorbent, producing a purified vancomycin. Purified vancomycin is then crystallized from the solution by adding a base solution that imparts a pH of above about 9.0 to about 9.5 to the purified vancomycin.  The crystallized vancomycin is separated from the solution, dissolved in solution and recrystallized by adding a base solution which imparts a pH of above about 9.0 to about 9.5 to the dissolved solution. The recrystallized vancomycin is dissolved and titrated with hydrochloric acid. Vancomycin .HCl is then precipitated from the solution using an organic solvent.

Abstract: Described is a shock absorber for improving the safety in passenger compartments of motor vehicles during impact accidents.  It is intended that the impact between the outer skin of bodywork parts such for example as doors and the associated inner lining in the passenger compartment shall be reduced.     For this purpose the shock absorber is in the form of an impact pot, in such a way that the energy absorption, at least to a considerable extent, is effected via a plurality of chronologically successive shearing procedures of the absorber material during an impact.  The impact pot is subdivided into shearing zones for the successive shearing procedures, which are defined along enclosed curves.  Advantageously, it is in the shape of a stepped pyramid or terrace arrangement with optional plan projections.

Abstract: A code division multiple access (CDMA) radio receiver (104) having gain receives a radio frequency (RF) signal (122) to produce a received signal (124). The quality (130) of the received signal (124) is determined (111). The quality (130) is preferably a ratio of an energy per chip of a desired signal (Ec) to a total power spectral density of the received signal (Io) (124). For alternative radio receivers (104) the quality (130) may be an error rate estimate of a demodulated signal (126). The gain of the radio receiver (104) is adjusted responsive to the quality (130) of the received signal (124) to optimize the quality (130) of the received signal (124). Further, since the adjusted gain also changes a received signal strength indication (RSSI) (242) of the received signal (124), the RSSI (242) of the received signal (124) is estimated (217) and compensated (218) responsive to the gain of the radio receiver (104) to produce a compensated RSSI (134) of the received signal (124) indicative of the RSSI of a desired RF signal (122).

Abstract: An input signal is supplied to a tapped-delay line adaptive filter to produce tap signals which are equally divided into groups. The tap signals are selectively coupled on a per group basis through a switch to coefficient generators where tap-weight coefficients are produced. The selected tap signals are weighted respectively by the coefficients and summed together to produce a correction signal, which is combined with an output signal which is a replica of the input signal. The coefficients are updated with a residual error of the correction signal. Using the coefficients, the hopping order for selecting a tap group and the dwell time of the tap group are determined. Total power of the selected tap signals is monitored. When the monitored power is lower than a threshold value, the determination of the hopping order and dwell time is disabled and the residual error is nullified for fast convergence.

Abstract: An aqueous pigment dispersion is formed of a pigment an aqueous medium and a dispersant resin. The dispersant resin contains a hydrophobic moiety and a hydrophilic moiety in its molecule. The hydrophobic moiety is a polyester linkage chain formed of ester linkages as primary linkages. The hydrophilic moiety is a water-soluble resin containing sulfonic groups or their salts. The water-soluble resin can be produced, for example, by reacting a polyol with maleic acid and/or fumaric acid to synthesize an unsaturated polyester resin and then adding acid sulfurous acid or its salt to the unsaturated polyester resin to form groups represented by the following formula (I):   <see formula I>   wherein M1 represents a hydrogen atom, an alkali metal, an ammonium group or a lower aliphatic quaternary ammonium group.
