Granted: 1992-03-31
Abstract: ABSTRACT           A system for automatically controlling the gain bandwidth  product  of  multiple  operational  amplifiers fabricated on the same chip, in which one of the amplifiers forms a reference amplifier, and its gain bandwidth product is determined to provide a reference signal used to control a bias circuit determinative of the gain bandwidth products of all the amplifiers, the value of these products being determined by the frequency of a square wave control signal applied to  an  input  of the reference  amplifier.   The reference amplifier is highly compensated and placed in the configuration of voltage follower so as to generate an alternating exponential ramp signal,  which is rectified to provide a series of ramps of common polarity and applied to a voltage to current converter to provide a current signal dependent on the frequency of the control signal and the gain bandwidth product of the reference amplifier. The difference between this current and a reference current provides the reference signal.

Abstract: ABSTRACT OF THE DISCLOSURE         In a method of and a system for unpacking bales each tied by at least one strap, a contact plate member provided with a strap sensor unit is mounted, through a biasing arrangement, on a body frame for movement relative thereto.  The body frame is moved toward a confronting side face of the bale to bring the contact plate member into contact with the side face of the bale.  The body frame is further moved toward the bale while increasing biasing force of the biasing arrangement, until contact pressure, with which the contact plate member is urged against the side face of the bale, reaches a predetermined value.  When the contact plate member is urged by the bale in such a direction as to increase the biasing force during scanning of the strap sensor unit along the side face of the bale, the body frame is moved away from the bale to maintain the contact pressure at the predetermined value.  When the strap sensor unit detects a position of the strap of the bale, the body frame is moved to bring a strap handling unit such as cutter or clamps mounted on the body frame, into engagement with the strap.

Abstract: (in conjuction with Fig. 4) To increase the output of a packaging machine especially for hinge-lid packs produced from individual blanks, the latter are fed to folding member (folding turret 31) along two parallel tracks (blank tracks 39,40). To guarantee faultless and efficient conveyance of two blanks at a time, the blank tracks (39,40) are arranged at a distance from one another which is greater than the distance between pockets (32,33) of the folding turret (31), into which the blanks are to be introduced simultaneously. As a result of a transversely directed movement, the blanks are moved toward one another into the position for pushing into the pockets (32,33).

Granted: 1993-04-06
Abstract: VERSATILE INTERFACE MEANS FOR COMPUTER-BASED CONTROL SYSTEMS              ABSTRACT OF THE DISCLOSURE      A computer implemented control system which includes interface circuitry by which signal intelligence is taken in to the computer from external devices such as sensors and is fed out from the computer to external devices such as actuators which correctively adjust controlled parameters.  An interface circuit for each of the several external devices is made "universal" in that either an analog input, bistate input, analog output, or bistate output device may be connected to any given one of the terminal points.  A voltage follower amplifier sends the intelligence signal to an output device through a low-cost diode, with negative feedback taken from the downstream side of the diode.  When an input device is elected for a given terminal point, simple program editing assures that the diode will be reverse biased to isolate the amplifier from the input signal path. In addition, inaccuracies in the analog output voltage fed to an output device --arising from contact resistances in a separable connector-- are drastically reduced by a dual-path separable connector arrangement which provides two independent circuit convections for the output voltage and for negative feedback.

Filed: 1989-07-19
Granted: 1993-03-30
Abstract: Abstract of the Disclosure A method of using a mathematical model to adaptively control surface roughness when machining a series of workpieces or segments by: (a) linearizing a geometrical surface roughness model; (b) initializing said model essentially as a function of feed; and (c) subjecting the initialized model to computerized estimation based on roughness and feed values taken from the last machined workpiece, thereby to determine the largest allowable feed for attaining a desired surface roughness in subsequently machined workpieces or segments of the series.  The mathematical model is an algorithm of the form R = [1262.79]?2/r.  The model is linearized and initialized to give the form R = B1sRf+B2Rmax where R is the actual roughness and Rmax is desired roughness, f is actual feed, B1 and B2 are coefficients to be updated by estimation, and sR is a scale factor chosen to make the first term have the same order of magnitude as the second term.  Computerized estimation is carried out by converting the above initialized linear model to vector matrix notation with provision for the estimated coefficients in the form Rn = .THETA.Txn, where Rn is measured roughness, xn is a computed vector taken from measured feed, and .THETA. is a vector to be estimated with "T" denoting the transpose of the vector.  After inserting roughness and feed values into such vector model, taken from the last machined workpiece, the coefficients are recursively estimated by sequential regression analysis.

Granted: 1993-05-11
Abstract: VARIABLE RATE BOAT LOADER                ABSTRACT OF THE DISCLOSURE    A variable rate boat loader includes a frame having transverse front, rear-powered and rear-pivot rollers.  Two pulleys are mounted on the boat gunwales between the boat's bow and center of gravity.  Two winch lines are connected at one end to the powered roller in laterally spaced position.  Each line extends forward atop the vehicle, upward around the front roller, and back over the frame and lengthwise of the boat to the pulleys.  The lines extend through the pulleys, forward to the frame, over the pivot roller to be supported thereby, and down to the stern of the boat.  The lines are supportingly connected to the stern of the boat.  This arrangement provides a doubled mechanical advantage in lifting the boat from the ground up to the level of the frame.  From this level, as the effective load being lifted decreases, the mechanical advantage decreases while the lifting speed increases.  The winch lines automatically bind the boat to the front roller and pivot roller when the boat is fully loaded.
