Patent CA-2129688-A1 (CA)
Title: Granular spreader
Inventor: WHITELL DAVID
IPC: E01C19/20
Filed: 1994-08-02
Abstract: A spreader for granular material such as sand comprises a trailer adapted to be pulled behind a vehicle such as a tractor or other utility vehicle.  A frusto-conical bin forms a hopper for a granular material to be dispensed and directs the material into a spreader housing where the material is impelled outwardly through a discharge opening by a rotating impeller.  The impeller and an orbital rotating bin sweep arm are driven by coaxial drive shafts via a belt and pulley mechanism.  A frictional tire engages the upper rim of the bin and propels the sweep arm in an orbital path.  The material discharge rate and discharge pattern are controllable by a slide gate and interchangeable cover plates which vary the size of the discharge opening.  The impeller and bin sweep assembly may be driven by an internal motor or from the towing vehicle by a power take-off drive.

Title: Semiconductor modulator with a shift
Inventor: YU JUN
IPC: G02F1/015
Filed: 1996-05-08
Abstract: A MQW semiconductor Mach Zehnder phase modulator is formed by two Y-junctions (12, 32), each having a single waveguide (14) optically coupled with two branch waveguides (18, 20). The branch waveguides of the two Y-juntions are optically coupled in Mach-Zehnder configuration that, under zero bias conditions, has one interferometric arm longer than the other to provide a .pi. phase shift. The additional length is preferably accommodated in the branches of the Y-junctions. The phase shift, in combination with voltage dependent absorption properties and non-linear phase variations of the MQW guided regions in the Mach-Zehnder modulator results in a negative chirp and high extinction ratio for an equal, push-pull device configuration.
