摘要:
The present invention relates to novel halohydrin dehalogenase polypeptides and the polynucleotides that encode them. These polypeptides are useful in the production of 4-substituted-3-butyric acid derivatives and vicinal cyano, hydroxyl substituted carboxylic acid esters. The invention also provides related vectors, host cells and methods.

A high volume air sampler is disclosed. The high volume air sampler is adapted to draw samples of air that will be passing through the interior of an airplane's interior fuselage. The air may be drawn from a bleed valve of a gas turbine engine that supplies the air to the airplane interior. The high volume air sampler draws a sufficient volume of air so that sampling methods and/or detectors can detect airborne impurities. The high volume air sampling system includes the use of flexible hose for receiving engine bleed air. The system also includes a collar that adapts the flexible hose for use with a sample canister.

A pressure reduction apparatus is disclosed. Air at high pressure and temperature may be drawn from a source such as a bleed valve of a gas turbine engine that supplies the air to an airplane interior. The air is passed to a pressure reduction vessel. The vessel has sufficient volume such that the high pressure air, upon entering the vessel, will reduce in temperature and pressure. The pressure reduction apparatus allows the air to depressurize and drop in temperature to near ambient conditions. Upon exiting the pressure reduction apparatus, the air is at a temperature and pressure sufficient to allow the air to be sampled and analyzed by conventional equipment used for testing for airborne impurities such as semivolatile compounds ad particulates.

A folder operable to cut a printed web received from a printing press. The folder includes a cutting section having cutting cylinders that cut the web into individual printed products, and a cutting motor that is operable to drive the cutting cylinders. A delivery assembly of the folder includes delivery belts that are operable to guide the individual printed products through the folder, and at least one delivery motor is operable to drive the delivery belts. The folder also includes a diverting assembly that diverts individual printed products to one of a plurality of collation paths, and a diverting motor that is operable to drive the diverting assembly. The cutting motor, the delivery motor, and the diverting motor are operable independently of one another.

The present invention generally relates to methods of rapidly and efficiently searching biologically-related data space. More specifically, the invention includes methods of identifying bio-molecules with desired properties, or which are most suitable for acquiring such properties, from complex bio-molecule libraries or sets of such libraries. The invention also provides methods of modeling sequence-activity relationships. As many of the methods are computer-implemented, the invention additionally provides digital systems and software for performing these methods.
摘要:
A method of treating early papillomavirus infection of an orifice of a human or animal body including any canal associated with an orifice, comprising applying a viral inactivation agent to the orifice and/or canal in an amount effective to inactivate a portion of the virus infecting the orifice or canal. Apparatus is also disclosed.
摘要:
An air contamination monitor includes a sample heater connectable to an air source such as an aircraft engine bleed air port. The heater causes any oil and other hydrocarbons in the sample air to decompose into CO.sub.2 and H.sub.2 O. A vacuum pump draws the heated air sample from the heater to a carbon dioxide analyzer. The response of the analyzer is recorded by means of a strip chart or paperless recorder.
摘要:
A gas meter assembly having a universal type connector subassembly. This gas meter assembly includes a gas meter, inlet piping, outlet piping, and a connector unit which has a U-shaped inlet pipe, a Z-shaped outlet pipe, and a strut fixedly connected to the U-shaped inlet pipe and connected to the Z-shaped outlet pipe. The strut has a first hole with a first axis receiving the inlet pipe and has a second hole with a second axis receiving an upper portion of the Z-shaped outlet pipe for rotating through a selective angle a lower portion of the Z-shaped outlet pipe with a third axis, so that the spacing between the first and third axes can be made either more or less than the spacing between the first and second axis, in order to match the spacing between inlet and outlet connections of the meter.
摘要:
A device for facilitating the placement of particulate solids into voids. In particular, the device allows boreholes to be filled with a particulate solid material with a reduction in the amount of turbulence thereby allowing the achieving of the proper density for the particulate material. The device includes an improved mantle mounted adjacent the outlet end of the particulate material supply tube for separating the particulate solid material from liquids and gases. The mantle has a perforated portion in contact with the supply tube and a solid portion in contact with the borehole.
摘要:
Compositions of matter suitable for use as a fertilizer and comprising a mixture of water; one or more materials capable of acting as a fertilizer; and at least one agent comprising at least one organic water soluble or water hydratable material capable of thickening said mixture and present in an amount sufficient to convert said mixture to a water resistant gel form.
