Patent CA-1191579-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed   is   a  method  and  apparatus   for estimating yaw error and roll and yaw disturbance torques from measured roll error and yaw momentum on a continuous on-orbit basis in an orbiting satellite.  The information thus obtained can be used to continuously correct for the yaw error by means of,  for example, activating a magnetic torquer.  Two control loops are used in this invention, a fast  loop to damp  nutations  by changing  momentum wheel speed, and a slow loop of the Luenberger observer variety. The latter is a yaw error correction loop which also serves to  unload  yaw  momentum.   The  satellite  in  which  the invention  was  first  incorporated  is  of the  type having three momentum wheels, all situated in the plane orthogonal to the roll axis.  In normal operation,  two wheels,  each having major momentum component along  the pitch axis and minor momentum component along the yaw axis, are operable. A third backup wheel  aligned  along  the yaw axis becomes operable only in the eventuality that one of the primary wheels  suffers  a  breakdown  during  the  life  of  the satellite.  The slow speed yaw loop is used to adjust a magnetic coil torquer.  It can be implemented in a number of forms  including a hard-wired analog form or a digital computer with certain constant scaling factors programmed into the memory of the computer.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for continuously using ink and dampening fluid in a printing system includes removing ink and dampening fluid from a form roller after the form roller engages the printing plate. Mixing of the removed ink and dampening fluid to form a substantially homogeneous printing liquid is accomplished by circulating the removed ink and dampen-ing fluid to a reservoir where it is mixed with ink in the reservoir by an auxillary blender.  The homo-geneous mixture is further circulated to the center of a metering nip between two rollers and flows lon-gitudinally of the rollers at a rate to prevent separ-ation of the dampening fluid from the ink.  Unused printing ink and dampening fluid is returned to the reservoir with the ink and dampening fluid removed from the form roller.

Abstract: ABSTRACT OF THE DISCLOSURE           A control circuit is used during slow or stop-motion playback operation of a video tape device to drive video tape intermittently.  In order to avoid errors in the stopping position of the tape, a pulse width modulated (PWM) signal is provided to a motor controller circuit associated with the capstan motor of the video tape device.  A frequency signal generator coupled to this motor generates a frequency signal that varies with the capstan motor speed, and this frequency signal is provided to a retrigger monostable multivibrator which generates a PWM signal whose duty ratio changes in proportion to the capstan motor speed.  A drive pulse generator and a brake pulse generator provide drive start and brake start signals, respectively, when it is desired to commence and stop movement of the tape.  A drive circuit, including the retrigger monostable multivibrator, receives the drive start signal, the brake start signal, and the frequency signal to generate the PWM signal which is supplied to the motor controller circuit.  The frequency signal is selected to have a pulse rate several tens of times the ripple frequency of the motor's torque ripple characteristic so that inaccuracies in stopping position of the motor are eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE       An assembly of top and bottom plates spaced apart vertically by peripheral and intermediate spacer bars forming a shelf of freeze drying or other processing equipment, is held together on a movable base support-by peripheral clamps mounted removably at selected positions on the base support.  A hollow framework carriage is mounted on the base support for movement above and relative to the shelf assembly and it supports a pair of elongated, laterally spaced clamp bars for retractable movement toward and away from the base support for releasab-ly clamping therebetween interposed portions of the shelf assembly.  A laser welder then is moved relative to the clamp assembly to weld the components together in the clamped areas.  Upon completion of the welding operation, the clamp bars are retracted and the framework moved over the base support and assembly to the area next to be welded, whereupon the clamp bars are extended into clamping position and the welding operation is repeated.

Abstract: ABSTRACT     In conventional electrical circuits interface or contact resistance between two current carrying conductors produce one of the most uncontrollable, and hazardous parts of the circuits.  Due to numerous factors including wear, corrosion. temperature cycling and loss of temper, the contact resistance rises above its original design value after the equipment has been in use.  This increase in contact resistance causes an increase in heat generated at the electrical interface, and as a result, further deterioration of the interface.  The resulting cumulative increase in contact resistance is one of the major contributing factors in electrical failures and fires.  This invention utilizes the undesired heat generated as electrical current passes through contact resistance to limit and/or reduce the value of the contact resistance, and thereby limit heat generated by the passage of the electrical current through the contact resistance.  This invention significantly reduces the danger of electrical failures and fires, and increases the useful life expectancy of a wide variety of electrical fittings, devices, and equipment,

Abstract: ABSTRACT OF THE DISCLOSURE      A grinding system is controlled by (1) determining the exact nature of a power function relationship between (a) the rate at which material is removed from one of the surfaces at a rubbing interface and (b) the feed rate at which the rubbing surfaces are fed into each other, for a particular grinding operation, i,e., a particular grinding wheel and other specified conditions affecting the rate of material removal at the rubbing interface; and (2) controlling, measuring or setting the material removal rate or the feed rate in such a grinding operation in accordance with said power function relationship.     In one embodiment for grinding a workpiece at a desired grind rate GR while simultaneously truing the grinding wheel, the control system includes the steps of determining the relationship between the wear rate R'wg of said grinding wheel and the feed rate Fw at which said grinding wheel is fed into said workpiece; grinding said workpiece with said grinding wheel while simultaneously truing the grinding wheel with a truing element; determining the wheel wear rate R'wg (at the grinding interface) corresponding to the desired grind rate GR from the previously determined relationship between R'wg and Fw; advancing the grinding wheel toward the workpiece at a controlled rate Fws which is approximately equal to the sum of the desired grinding rate GR, the corresponding wheel wear rate R'wg (at the grinding interface), and the rate R'wt of reduction in the wheel radius at the truing interface; and feeding the truing roll toward the grinding wheel, on the opposite, side of said wheel from the workpiece, at a controlled rate Fts which is approximately equal to the sum of R'wg and R'wt.

Abstract: ABSTRACT      A door closer for regulating the movement of a door panel with respect to its frame has a body enclosing a chamber and an adjacent cylinder having a head.  A piston is reciprocable in the cylinder toward and away from the head and in accordance with the door panel motion.  A spring in the chamber urges the piston toward the head. A duct through the piston controlled by a check valve permits liquid flow from the chamber to the cylinder, but not vice versa.  A passage in the body extends between the cylinder, near the head, and the chamber.  In that passage near the head is a throttle valve for restricting liquid flow, and in the passage near the chamber is a by-pass valve for restricting liquid flow and for permitting increased flow under increased liquid pressure.  There is also a bore in the body extending between the passage intermediate the throttle valve and the bypass valve and an adjacent part of the cylinder traversed by the piston.
