Inventor: BREZETTE MICHAEL W
IPC: B05C17/00
Filed: 1989-12-29
Abstract: ABSTRACT       A pad attachment for a paint roller assembly including a pad holder affixed to a roller type paint applicator.  The pad holder retains a paint trimming and smoothing material in a form of a fabric or foam.  The material retained by the holder is positioned to smooth or otherwise treat the paint being applied by the roller during a painting application.  In addition, the material may function to trim or "cut in" at the interface of a surface adjacent the surface being painted.  In an alternative embodiment, the invention may be part of a paint roller assembly having an adjustable splatter shield.  The pad holder is integrally formed with the shield and is removably retractable and extensible along with the shield.

Abstract: An improved process for the preparation of a valuable drug.  The present invention relates to an improved process for the preparation of Fluoxetine hydrochloride, used as an antidepressant, i.e. N-methyl-3-(p-trifluoromethylphenoxy)-3-phenyl-propylamine hydrochloride, by catalytic hydrogenation of 2-benzoyl-N-benzyl-N-methylethylamine base with the aid of Pt/C or Pd-Pt/C at a hydrogen pressure of 5 bar at 50°C, with ethyl acetate as a solvent, whereby 1-phenyl-3-(N-methylamino)-propane-1-o1 is produced.  This compound is etherified selectively by using 1-chloro-4-trifluoromethyl-benzene in N-methyl-pyrrolidone at 80°C in the presence of potassium iodide and by using potassium-t-butoxide as the base, whereby N-methyl-3-(p-trifluoromethylphenoxy)-3-phenyl-propylamine,, i.e.          Fluoxetine base, is formed, which is converted in a known manner into Fluoxetine hydrochloride, i.e. N-methyl-3-(p-trifluoro methylphenoxy)-3-phenyl-propylamine hydrochloride.  The yield of Fluoxetine hydrochloride is 85-87% of the theoretical yield.

Title: Solid state scanning transducer that utilizes low flux densities
Inventor: GOOCH BEVERLEY R
IPC: G11B5/33
Filed: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE A magnetic transducer arrangement includes a core with a gap and a body of magnetically anisotropic material in which a signal transfer region is defined. Control flux flows across the gap of the core and through the body in two opposite directions.  The two oppositely directed flux flows influence one another and tend to cancel each other to define a null zone. This null zone, in which the flow of control flux is very low, is sensitive to flux emanating from a adjacent magnetic storage medium and therefore defines the signal transfer region.  By varying the relative proportions of control flux flowing in the two opposite directions, the location of the null zone can be varied along the width of the magnetic transducer to thereby scan the signal transfer region.  The flux which is coupled from the magnetic storage medium into the null zone of the body does not flow through the magnetic core in a manner similar to a fringing flux.  Rather, this flux is used to modulate a bias flux, and this modulation is detected to reproduce the recorded information.  In a recording mode, information flux reduces the permeability of the signal transfer region, causing the flux to fringe from the body and be coupled into the storage medium.
