Patent CA-2074827-A1 (CA)
Inventor: JAEGER NICOLAS A
IPC: G01R1/067
Filed: 1991-01-31
Abstract: An integrated optics Pockels cell for use in a voltage sensor includes a crystal exhibiting the electro-optic effect in which an integrated straight line wave guide substantially aligned with a z axis of the crystal is incorporated.  The wave guide has two substantially orthogonal polarization axes substantially aligned with an x and y axis of the crystal respectively. In operation light polarized at a selected angle of orientation to the x and y axes of the crystal is applied to one end of the wave guide and polarized light leaving the wave guide and polarized along two substantially orthogonal axes one of which is at about the same orientation to the x and y axes as the polarized light entering the wave guide is detected to determine the electric field to which the sensor has been subjected.     Preferably the sensor will include polarization maintaining optical fibres appropriately oriented to the wave guide for delivering and receiving polarized light to and from the wave guide.

Title: Process for the desulphurization treatment of pig iron melts
Inventor: ABELE KARL-HEINZ
IPC: C21C1/02
Filed: 1992-08-24
Abstract: ABSTRACT          The invention relates to a process for the desulphurization treatment of a pig iron melt in a container.  The characterizing feature of the invention is that the treatment is performed in three phases:          In the initial phase such solids are injected that deoxidize the initial slag and increase its basicity and also produce a circulatory movement of the melt and form a basic deoxidized cover slag.  In the middle phase the desulphurizing agent is injected for the main desulphurization and in the final phase such solids are injected that purify the melt and produce a final desulphurization and also so influence the desulphurization slag formed that its content of iron granules is low.

Title: Filaments dispersing device
Inventor: ISHII HIROSHI
IPC: D04H3/16
Filed: 1992-04-09
Abstract: ABSTRACT       An object of the present invention is to provide a dispersing device which can disperse filaments uniformly and widely on a moving collector surface by suppressing the turbulence of an air flow as a carrier medium for the filaments to thereby reduce the disturbance of the fila-ments.     The dispersing device (1) of the present invention is formed as a dispersing pipe consisting of a pair of dis-persing plates (2) vertically extending so as to be op-posed to each other and a pair of side plates (3) connect-ing the dispersing plates.  The dispersing pipe has an upper end formed with a filaments inlet and a lower end formed with an oblong filaments outlet (5) surrounded by the dispersing plates and the side plates.  The dispersing pipe has a shape such that a space t between the dispers-ing plates is decreased with an increase in distance z from the filaments inlet toward the filaments outlet (5) and that a space w between the side plates is increased with the increase in the distance z.  According to the dispersing device of the present invention  the turbulence of the carrier air flow is reduced to thereby uniformly and widely disperse the filaments on the moving collector surface (14).  Accordingly, a web having a good appearance with less nonuniformity and less yarn bundles can be ob-tained.

Abstract: Abstract FIBER-OPTIC AMPLIFIER WITH        CONTROL OF THE PUMP LIGHT WAVELENGTH     In fiber-optic amplifiers, for example those including a light waveguide piece (1) doped with Er3+, the wavelength of the pump light generated by the pump light source (2) must lie as precisely as possible at that wavelength that is desired as the pump light wavelength for the amplifying light waveguide piece (1).  Deviations from this wavelength considerably adversely influence the performance of the optical amplifier.  According to the invention, the fiber-optic amplifier includes a control device which regulates the wavelength of the pump light generated by the pump light source (2) to the absorption maximum lying at the desired wavelength.  Preferably this is done in that part of the pump light is coupled into a reference light waveguide piece (10) which has its maximum absorption at the same wavelength as the amplifying light waveguide piece (1) and in that the absorption in the reference light waveguide piece (10) is used as a criterion for the regulation.

IPC: B05B9/01
Filed: 1993-05-31
Abstract: A paint spray gun having a dual operating mode trigger. The trigger pivots on a gun body about an axis. The two operating modes are selected by radially positioning the trigger relative to the axis. In a first operating mode, fluid flow to a nozzle is gradually increased as the trigger is gradually squeezed to permit fluid flow control for feathering the applied coating. In this mode, the trigger is mechanically linked for actuating a valve needle. In asecond operating mode, a small actuating movement of the trigger operates a valve which causes a piston to move the valve needle to its fully open position. The second operating mode provides only on-off fluid control with a very short trigger stoke and a low trigger force.
