Title: Method of controlling polarization properties of a photo-induced device in an optical waveguide and method of investigating structure of an optical waveguide
Inventor: INNISS DARYL
IPC: G02B6/27
Filed: 1995-01-25
Abstract: A method of controlling the polarization properties of a photo-induced device in an optical waveguide and a method of investigating the structure of a light guiding body such as an optical waveguide are disclosed.  A device, such as gratings, is written by exposing one side of the optical waveguide to light.  The unexposed side is then exposed to an amount of light sufficient to impart the desired birefringence to the written device.  The birefringence can be minimized in the written device by exposing the opposite side to light in an amount sufficient to minimize the amount of birefringence.  The light guiding body is investigated by cleaving the elongated light guiding body, such as an optical waveguide, to expose its cross-section.  The cleaved section is then treated to expose difference between the core and cladding.  Treatment may include etching in an acid or base.  The cross-section is then profiled with a scanning probe microscope such as an atomic force microscope to investigate the structure of the light guiding body.  The difference in refractive index can be determined across the cleaved endface based on differences in the etched depth.
Patent CA-2141783-A1 (CA)
Title: Phase responsive fluid delivery
Inventor: CLARK JOHN K
IPC: F17C7/02
Filed: 1993-08-09
Abstract: A system for delivering fluid, e.g. liquefied petroleum gas or "LPG", through a delivery path (10) under pressure. A delivery control valve (16) is selectably operable to close and open the delivery path (10) and monitors a parameter of the fluid, e.g.  dielectric constant, and to sense the presence of vapour or gas phase in the fluid. A control means (30) responsive to the indicating signal from the sensing means (20) causes the delivery control valve (16) to close the delivery path upon sensing the presence of a significant proportion of vapour or gas phase in the fluid. A gas introduction point (35) upstream of the sensing means (20) enables gas to be introduced so as to knowingly expose the sensing means (20) to fluid containing gas phase and thereby enable controlled testing of the correct functioning of the sensing means (20).  In the case of the fluid being liquefied gas, pumping  means (45) upstream of the sensing means (20) can continue operation after closure of the delivery control valve (16) so that the gas or vapour phase will undergo compression and as a result will liquify and the control means (30) will then cause re-opening of the delivery control valve (16). The closure of the delivery control valve (16) prevents liquefied gas having a significant proportion of gas or vapour phase passing through a metering means (15) downstream of the sensing means (20).

Inventor: MEYERS PHILIP E
IPC: A01F12/44
Filed: 1995-02-10
Abstract: An air flow deflector panel for insertion into existing combines of the axial flow type without modification to the combines for changing the direction of air flow from the cleaning fan to the sieve section.  The air flow deflector panel includes a plate having mounting brackets for attachment to the existing structure of the combine for holding the plate which extends across the separation chamber behind the outlet of the throat of the cleaning fan.  The plate includes an angled portion for directing a required portion of the air beneath the sieves past the front portion thereof.  The air flow deflector panel accomplishes more effectively separation of the straw and chaff from the grain being collected below the sieve section than is currently possible with certain models of combines of the axial flow type and further eliminates the use of a higher air flow which can in any event result in a portion of the grain being expelled with the debris.
