Abstract: ELECTRET FILTER MADE OF FIBERS CONTAINING POLYPROPYLENE AND POLY(4-METHYL-1-PENTENE                        ABSTRACT           A fibrous electret filter better sustains electret filtration enhancement upon exposure to aerosol oils when made of fibers containing polyolefin (preferably polypropylene) and at least one percent by weight of poly(4-methyl-1-pentene).  Even better stability is attained when the poly(4-methyl-1-pentene) content of the electret filter is ten percent by weight of total polyolefin.  When used as an air filter, such as in a respirator, the electret filter has surprisingly better filtration performance than does a comparable electret filter made of 100% polypropylene fibers.  The electret filter can be made either of melt-blown microfibers or of fibers of fibrillated film.

Title: Non-intrusive process for monitoring the production of recombinant proteins
Inventor: WONG PATRICK T T
IPC: C12N9/36
Filed: 1989-01-04
Granted: 1993-09-21
Abstract: Abstract:      A process is described for monitoring the production of recombinant proteins. It is based on the discovery that infrared spectra of E. coli strains and transformants which overproduce recombinant proteins can be measured as a func-tion of pressure, and a pressure-induced distinct shifting pattern can be observed in specific spectral parameters of transformants.  In particular, the difference in the pressure-induced shift of the amide III band, between the E. coli cells and the transforms over-producing the recombinant proteins provides an efficient and production of recombinant proteins in E. coli.

Title: Sensing a narrow frequency band of radiation and gemstones
Inventor: STEWART ANDREW D G
IPC: G01N21/86
Filed: 1989-05-08
Granted: 1995-03-28
Abstract: In order to sort diamond-bearing ore particles conveyed on a wide belt, exciting radiation strikes the belt along an extended line.  Diamonds are detected by passing the emitted radiation through a narrow band pass filter and sensing the Raman radiation with a photo-multiplier tube.  Only axial-parallel rays passing through the filter reach the photo-multiplier tube.  An array of side-by-side converging lenses can be used, the lenses being of rectangular shape as seen looking along the optical axis with their long axes at right angles to the line of radiation.  The ore particles are in the plane of the foci of the lenses, so that radiation emitted by each particle is passed in parallel rays through the filter.  In order to stop rays having an angle of incidence greater than the maximum permitted, to avoid identifying non-diamond material as diamond, a further converging lens is used to focus the rays at the plane of a telecentric stop.  The stop stops rays having too great an angle of incidence.  The position of the diamond can be detected for instance by a CCD array or by a time domain technique.  The apparatus can be monitored by giving a signal when the radiation from tracer stones and holes on either side of the belt, differs from predetermined values.

Abstract: ZERO-TORQUE EDDY CURRENT MOTOR SYSTEM    AND METHOD FOR CONTROLLING SAME                            ABSTRACT     A variable speed eddy current electric motor and method for controlling such an eddy current electric motor is disclosed.          The variable speed eddy current electric motor includes a zero torque  regulating  circuit  for  sensing  and  responding  to  the current flowing through an eddy current motor field coil.  As the magnitude of the field coil, current is changed by the eddy current motor's speed control circuit, the zero-torque regulating circuit supplies varying amounts of current to flow through the field coil in a direction opposite to that of the current applied thereto  by  the  speed  control  circuit.   Thus,  when  the  eddy current  motor's  speed  control  circuit  no  longer  causes  any current to flow through the field coil, the current supplied to the field coil by the zero-torque regulating circuit produces a magnetic filed that removes all torque from the eddy current motor's output shaft.
