Title: Racemization process for optically active carboxylic acids or salts or esters thereof
Inventor: MANIMARAN THANIKAVELU
IPC: C07C51/487
Filed: 1997-06-10
Abstract: Optically active carboxylic acids, salts or esters, such as the profen-type compounds, are racemized in the presence by nitrogenous bases such as methylbenzyl-amine by heating an aqueous solution of such optically active compounds at a temperature of from 80 ~C to 200 ~C in the presence of a catalytically effective amount of an alkali metal hydroxide. The process not only enables conversion of inactive or undesirable enantiomers of compounds such as Naproxen or Ibuprofen into a usable, desirable enatiomers in an efficient and economical manner, but avoids conversion of the nitrogenous base into amide. Thus the deleterious consequences of amide formation are avoided.

Patent CA-2271559-A1 (CA)
Inventor: SYMONDS DANIEL H
IPC: B26D1/18
Filed: 1997-11-06
Abstract: A pattern for a casting process machined from a billet material according to a basic, programmed, five-axis machining process to form multiple copies of a reproducible complex pattern body (18). Machining the complex patterns (18) and producing variations by changing the machine program permit multiple bit patterns of variable forms to be produced without need for building an intermediate, reusable pattern mold that would require multiple mold pieces. The pattern is machined in a single chucking operation in a machine tool (26) adapted for machining plastics in a three-dimensional global process. Bit patterns formed in the process have forward canted blades (35) that are machined from mating planar surfaces to simplify the machining process. Forward canting makes the blades (35) stronger and thus permits the blades (35) to be thinner than non-canted blades to increase the clearance between blades (35), which improves the movement of cutting past the bit.

Title: Method and apparatus for reducing windage losses in rotating equipment and electric motor/generator employing same
Inventor: NIGGEMANN RICHARD E
IPC: H02K5/12
Filed: 1998-03-17
Abstract: A rotating flood cooled machine having reduced windage losses comprises a stator having an inner periphery and a rotor rotatably positioned within the stator separated from the stator by a gap which is filled with fluid. A film divider is rotatably positioned within this gap and is allowed to rotate freely. In such a machine, when the rotor rotates at a speed .omega., the film divider is caused to rotate at a speed of approximately .omega./2. At this speed, the film divider obtains a radial position during rotation of approximately midway between the outer periphery of the rotor and the inner periphery of the stator. This radial position is preferably maintained by the hydrodynamic bearing action of the fluid within the gap, or alternatively through the use of radial positioning or retaining mechanisms. The use of axial constraint mechanisms to maintain the film divider within the air gap under the shear forces of the fluid during operation is also contemplated. The film divider may also include a plurality of holes to facilitate a flow of fluid within the air gap. This flow may be further facilitated within and through the air gap by dividing the film divider in two halves along a midline. A method of reducing the windage loss of a rotating flooded machine, such as, e.g., an electric motor or generator, comprises the steps of placing a film divider in the gap between the rotor and stator and allowing this divider to rotate freely therein during operation.
