Patent CA-1221425-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         A fluorescent display tube power supply device in a microwave oven comprises circuitry for generating a stable voltage supply for a microcomputer by rectifying the output of a first secondary coil of an AC power transformer, and rectifying a half wave of the output from a second secondary coil of the transformer, one-half cycle of which is applied to a heater of the fluorescent display tube.  A rectifying circuit generates a double voltage from the out-put of the second secondary coil, the double voltage being mixed, in direction in which it becomes lower than the stable voltage of the microcomputer, thus providing a display erase  potential.  As a result, the luminance of the display can be maintained constantly unaffected without causing the voltage of the display tube to vary throughout ON-OFF opera-tions of the heating power source, thus achieving a highly satisfactory display effect.

Abstract: Abstract of the Disclosure A signal  coupling circuit suitable for use in a high-speed signal acquisition probe comprises separate high-frequency  and  low-frequency  signal  transmission paths  from  input  to  output.  The  low-frequency path includes  a  mechanism  for  variably  shifting  the  DC voltage level at the circuit input to offset quiescent or average voltage levels of an input signal. Values of impedance elements for both the high-frequency and low-frequency  transmission paths may  be  selected  to provide predetermined input and output impedances with-out  compromising  signal  fidelity  or  limiting  signal bandwidth.

Granted: 1988-06-14
Abstract: ABSTRACT OF THE DISCLOSURE      A specific binding assay method and reagent system based on the use of an inhibitory anti-enzyme, e.g., antibody or fragment thereof, as the label component.  Such method and reagent system have been improved by selection of anti-(glucose-6-phosphate dehydrogenase) [anti-G6PDH] as the anti-enzyme label.          The improved label is monitored by its ability to inhibit G6PDH.  The resulting assay is more sensitive, requires lesser quantities of reagents, is less sus-ceptible to sample interferences, and employs a reagent system having greater stability than the pub-lished prior art method employing an anti-peroxidase label.  The present invention is particularly applicable to homogeneous immunoassays for determining substances appearing at low concentrations in biological fluids such as urine and serum.

Abstract: Abstract On  a  safety  can  for the  storage  and  dispensing  of liquid fuel and other volatile liquids from which the contents usually are dispensed at more or less frequent intervals, the pouring spout of the can has a cover which is at a free end of a lever which is spring biased to normally keep the cover tightly closed. The can has a fixed lifting handle in the form of a flat arch in a central area of the top of the can with the top of the arch providing a hand grip removed from the spout and its cover,  a  secondary handle extending above the lever on which the cover is secured and pivotally secured through an upwardly offset connection  to the lever toward the free end of the biased lever terminates in a hand grip parallel with but spaced radially from the hand grip formed by the flat arch. The can may be lifted by grasping the two parallel hand grips but the spout cover will remain closed until one's hand, grasping both grips, is tightened to pull  the hand grip of  the secondary handle in a generally horizontal, or radial,    direction toward the first to controllably lift the spout cover from the end of the spout to an open posi-tion. Up and down movement of said secondary handle is ineffec-tive to open the cover, radial movement alone being ineffective except lifting the can with the secondary lever alone held the spout cover more tightly closed.

Abstract: "GRAIN PICK-UP TEETH ASSEMBLIES       ABSTRACT OF THE DISCLOSURE         Conventional pick-up teeth are inefficient in picking up and retaining relatively short grain stems in the swath particularly if the grain stems are relatively slippery such as is the case with barley.   The present device consists of a pair of main prongs or teeth extend-ing from a common base in spaced and parallel relation-ship and having additional or secondary teeth or prongs extending from along the length of said main teeth in spaced and parallel relationship.  This allows the grain to be retained more efficiently and permits slower speeds of operation thus reducing the possibility of disengage-ment of the stems or stalks from the teeth.

Abstract: ABSTRACT An adjustable torque limiting assembly includes a first wrap spring mechanism which provides a readily adjustable torque transmission limit and a second coaxially disposed wrap spring mechanism which provides a mechanical signal that the torque limit has been reached.  This signal may be utilized to terminate an energy supply to a prime mover associated with the torque limiting assembly.  The first wrap spring mechanism generally includes a wrap spring in which the spring moment and thus the slip or overrunning torque threshold may be readily adjusted.  The second wrap spring assembly likewise includes a wrap spring which is activated only subsequent to slip of the first wrap spring and enlarges to engage a concentrically disposed control sleeve.  The control sleeve then rotates and activates an associated shut-off mechanism.  Drive from the first wrap spring assembly to an output shaft is through an overrunning clutch assembly which allows energy in the wrap springs to dissipate and the springs to wind down and return to their start positions when power to the torque limiting assembly is removed.

Abstract: GATED FIBER OPTIC ROTATION SENSOR               WITH LINEARIZED SCALE FACTOR                         Abstract A fiber optic rotation sensor, employing the Sagnac effect comprising all  fiber optic components positioned along a continuous, uninterrupted strand of fiber optic material.  The rotation sensor includes a detection system utilizing a modulator or modulators for phase modulating at  first  and  second  frequencies  light  waves  which counter-propagate through a loop formed in the fiber optic strand.   The  second phase modulation is at a frequency much lower than the first frequency and comprises a phase ramp signal which is applied to the counter-propogating light  waves.    The  phase  difference  modulation  which results  from  application  of  the  phase  ramp  defines  a substantially DC value which may be adjusted to bias the counter-propogating   light  wave   phase  difference   to substantially null the phase shift produced in the phase difference by the rotation rate.   Because the phase ramp modulation signal is simulated from a periodic waveform, an output signal from the sensor is gated synchronously with  respect  to  the  phase  modulation  at  the  second frequency so that the detected optical output signal is provided only during those intervals when it is influenced by the ramped portion of the phase modulation signal;    A phase sensitive detector generates a feedback error signal proportional to the magnitude of the optical output signal  at the  first  phase  modulation  frequency.    The feedback error signal controls a modulator which controls the amplitude of the second frequency driving signal for the phase modulator  such  that  the  signal at the  first phase modulation frequency in the output signal from the rotation sensor is substantially cancelled by the phase difference modulation produced at the  second modulation frequency  during  the  interval  when  the  optical  output signal is present.
