Title: Error-prone dna polymerase i mutants and methods for targeted random mutagenesis in continuous culture using error-prone dna polymerase i mutants
Inventor: LOEB LAWRENCE A
IPC: C12N1/21
Filed: 2003-05-29
Abstract: Mutant forms of DNA polymerase I having mutations within motif A and/or motif B in the active domain that increase error rates during replication.  Expression plasmid constructs and cell lines for expressing these low-fidelity polymerase mutants are provided. Methods are also provided for utilizing these low-fidelity DNA polymerase I mutants for generating libraries of randomly-mutagenized genes, which may be prokaryotic or eukaryotic.

Title: Acoustic devices to measure ultrasound velocity in drilling mud
Inventor: MOLZ ERIC B
IPC: E21B47/10
Filed: 2003-11-18
Abstract: An apparatus and method is disclosed for measuring ultrasound drilling mud velocity downhole in real time. One or more generated acoustical pulses are detected upon traversing two separate path lengths, and ultrasonic velocity is determined from differences in the pulses upon traversing their respective path lengths. Alternately, a single measurement can be made using an acoustic pulse traversing a specified path length. A transducer is discussed having a piezoelectric crystal, a backing material having matching impedance, and a facing material disposed between the crystal and the fluid having an impedance intermediate to crystal and fluid. A concave front face of the crystal increases sensitivity to off-axis signals. Improved signal resolution can be achieved using a controlled shape input pulse optimized for certain drilling conditions. A method of echo detection using wavelet analysis is preferred.
