Title: Reverse sample genome probing of sulphate-reducing bacteria
Inventor: VOORDOUW GERRIT
IPC: C12Q1/68
Filed: 1991-05-10
Granted: 2002-12-03
Abstract: A reverse genome probe process for detecting the presence of sulfate-reducing bacteria consists of: (a) obtaining an individual culture of at least one "selected standard" (which selected standard may be either a single sulfate-reducing bacterium or a group of more than one sulfate-reducing bacteria having homologous, cross-hybridizing genomes); (b) affixing a nucleic acid preparation from each selected standard to a solid surface; (c) preparing a "reverse" probe by labeling a nucleic acid preparation obtained from a sample taken from an oil field environment; (d) contacting the reverse probe with the solid surface under conditions which permit hybridization; and (e) detecting the presence of any reverse genome probe.      By using the "reverse" probe (i.e. a probe prepared from the sample, as opposed to a probe prepared from a selected microorganism), a single incubation may be used for the initial characterization of an unknown sample.

Title: Controlling plunger drives for fluid injection in animals
IPC: A61M5/172
Filed: 1994-08-02
Granted: 1999-03-09
Abstract: A computer-controlled injector (40) of the type having a motor which advances and retracts a plunger (12) located within a syringe housing (10) toward and away from a nozzle located in the front of the syringe to inject fluid into or withdraw fluid out of an animal subject.  Manual motion is induced by operating a manual motion control  (44-48);  the  operator  can manipulate  the  control  to indicate the desired direction and velocity of motion.  The manual motion control also has a locking mode in which manual motion of the plunger will continue once initiated without requiring the operator to continue manipulating the manual motion control.  The injector performs injections in accordance with one of several pre-programmed protocols, and automatically tracks the fluid volume remaining. The injector compensates for plunger extenders found in some partially pre-filled syringes by applying a stored offset value to the computed plunger position.
