Patent CA-2073438-A1 (CA)
Title: Motor controller having a control loop for neutralizing rotor leakage and magnetizing reactances
Inventor: STAATS GUSTAV W
IPC: H02P25/24
Filed: 1991-01-11
Abstract: A motor controller (10) for a single or multiphase induction motor (51) with control loop (59a, 59b, 59c) including auxiliary winding (61), capacitor (63) and saturable reactor (65). Auxiliary winding (61) is electro-magnetically coupled to stator winding (53, 55, 57) so the capacitive reactance of control loop (59a, 59b, 59c) is in parallel with the magnetizing reactance and the rotor leakage reactance of motor (51). The control loop (59a, 59b, 59c) is devoid of any direct electrical connection to motor (51). By varying the magnitude of current in D-C control winding (69), the inductance of reactor (65) is adjusted so the capacitive reactance of control loop (59a, 59b, 59c), as electro-magnetically reflected into motor (51), is in resonance with the parallel combination of the magnetizing reactance and the rotor leakage reactance.  Adjustment of reactor inductance, and of the capacitive reactance of control loop (59a, 59b, 59c), may be stepwise or continuous, either instance dependent on motor speed or applied frequency. The magnitude of the motor current is maintained or even reduced even though output torque is increased.

Filed: 1991-02-01
Abstract: Abstract A mowing machine has a frame with driving wheels, which are adjustable in height, and a yoke carrying a cutter beam.  The yoke is suspended from the frame such that it can move up and down with respect to said frame, and the cutter beam is swingably journalled on the yoke.  The yoke and the beam are balanced by an upwardly directed spring force.  Minor elevations on the ground just make the cutter beam swing upwardly so that it is just the weight of the cutter beam itself which is accelerated.

Title: Portable spectrophotometer
Inventor: BERG BERNARD J
IPC: G01J3/02
Filed: 1993-04-30
Abstract: PORTABLE SPECTROPHOTOMETER                     ABSTRACT OF THE DISCLOSURE         A portable spectrophotometer includes a small-diameter optical sphere (101) as well as optical detectors (131, 136) and signal processing and display circuitry (140, 142) which allows the instrument to be taken to an object to be measured and which provides a readout of color values at the portable instrument.          The instrument is capable of providing specular-included and specular-excluded color readings simultaneously.  The interior of the integrating sphere is coated with a highly reflective, color-absorbing material, and light from an incandescent lamp (103) is diffused within the sphere prior to reaching the object to be measured.  The sphere is provided with a first aperture (120) which receives spectrally-included light and which is positioned to absorb a spectral component of the diffused source light.  A second aperture (125) positioned at a corresponding angular position with respect to the object measures specular-excluded light, excluding the specular component absorbed by the first aperture.  By appropriately combining the specular-included and specular-excluded light at one wavelength, a value for the specular component is derived.

Title: Quick change mounted packer system
Inventor: KIRSCH JASON R
IPC: A01C5/06
Filed: 1993-10-06
Abstract: A new combination farm implement is disclosed. A cultivator is equipped with detachable mounted harrows and detachable packers. When the cultivator is used for direct seeding, narrow openers cut through the earth, and seed, transported from an air seeder by pneumatic means, is placed immediately behind the openers. Thereafter a series of packers, mounted to the rear of the cultivator, pack the seed. The invention lies in spring tensioned support arms which support the packers or harrows. Through various adjustments, these support arms can generate packing pressures from .5 psi to 3.5 psi, depending upon soil conditions. The same implement with the narrow openers and packers removed can be equipped with sweeps and mounted harrows and seed while cultivating to kill weeds or act as a general soil preparation device. The adjustable spring tensioned support arms are adjusted to relax downward pressure when the harrows are mounted in field operation. The unit as a whole, therefore, serves as a seeding or general tillage device, saving the operator extensive capital costs in farm machinery.
