Abstract: An intermediate plate positioner means for a multiple disk friction clutch assembly (10) is disclosed. A plurality of apertures (24a) are formed about the periphery of the intermediate plate (24). A positioner pin (42) is inserted in each of the apertures (24a) extending between the flywheel (12) and the cover (28) of the clutch assembly (10). Each positioner pin (42) is sized relative to its respective aperture (24a) so as to provide an interference fit therebetween. The force required to axially slide each positioner pin (42) through its respective aperture (24a) is predetermined to be less than the force generated by clutch springs (40), which urge the clutch assembly (10) toward an engaged position, but greater than the force exerted by the drive straps (34, 36) of the clutch assembly (10), which urge the intermediate plate (24) toward a disengaged position. As the friction faces (14a, 16a) of the clutch assembly (10) wear thinner during use, the position of the intermediate plate (24) relative to the clutch cover (28) in the disengaged position is varied by engagement of the positioner pins (42) with the flywheel clutch cover (28).

Abstract: A method for optimizing resource allocations in commercial enterprises that are characterized by a linear set of constraint relationships of the controllable parameters. The method is particularly useful in enterprises where the cost function to be minimized is piece-wise linear and convex, or where the cost function is linear and the constraint relationships are such that the enterprise can conveniently be decomposed into a plurality of relatively independent subentities and a correlating portion that expresses the interrelationships among the subentities. More specifically, in accordance with the disclosed method, an enterprise with a linear system of constraint equations that can be decomposed into a master problem and a plurality of subproblems leads to a need to solve a system of equations (corresponding to the master problem) where the cost function is piece-wise linear and convex. The piece-wise linear problem is solved by a method that is a modification of the algorithm invented by Karmarkar. The method moves iteratively within the polytope of feasible solutions (as in Karmarkar's invention) in a move direction that improves the value of the cost function. The move direction is ascertained scaling of the problem and determining a descent direction through a sensitivity vector evaluation, and the step size is determined through a line search along chosen direction to the best set of allocation values along that direction. Whenever possible, that direction corresponds to the steepest descent direction. The iterations are repeated until an optimal solution is found, whereupon the last evaluated set of allocations (controllable parameters of the system) is communicated to the system.

Abstract: The invention relates to a method in multi-colour silk screen printers for adjusting print in respective print positions. This is effected by registering print mate­rial to be calibrated in a laying-on position (7˝), and reading the position of the print material and storing the values obtained. The print material (7) is then printed in a first printing station, a second printing station, and so on, having knowledge of the positional settings of stepping motors (13,14,15), these positional settings being stored in a computer memory. The posi­tions of respective prints on the print material are evaluated (10′, 12′) in a laying-off position or station in the printer. 
     The next print in line can now be printed with the minimum of discrepancy, by first establishing the posi­tion of the print material in the laying-on station, with knowledge of the positions of the earlier prints and the then prevailing positional settings of the stepping motors.

Abstract: Disclosed is an optical disk handling system 124), called an autochanger, having two control systems (150Y, 150Z) to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders (62, 72) on two motors (60, 70) of the two control systems, and current or voltage feedback from the motors, for all positioning, and for detecting the location of the mechanisms during, and at the end of, moves. The shaft encoders (62, 72) are used to position a mechanism close to the eventual move location, then motor current or voltage feedback is used to determine the opposition to the movement of the mechanism, which tells the control system whether the mechanism has reached its destination. A human operator can enter a cartridge into the system through a mailslot (41), which is rotatable to properly receive or eject cartridges. The control systems use a flip assembly (49) in the autochanger to turn the cartridge over, allowing either side of the disk to be arranged for reading or writing by the optical drive. The control systems use a lateral displacement assembly (51) to move a cartridge from a cell in one of the two columns of the autochanger to a cell in the other column, or to move a cartridge between the optical drive, which is located in one of the columns, to a cell in the other column. The control systems use a cartridge engaging assembly (45) to attach to an exposed end portion of a cartridge positioned in a cell or the optical drive. A longitudinal displacement assembly (47) is used by the control systems to move the cartridge, after   attachment, out of the cell or optical drive. After positioning the cartridge vertically and laterally, the longitudinal displacement assembly (47) is then used to move the cartridge into a cell or the optical drive, where the engaging assembly (45) releases the cartridge. An important aspect of the invention is that the longitudinal displacement assembly (47), the flip assembly (49), the lateral displacement assembly (51), the engagement assembly (45), and the mailslot assembly (41) are operated by one of the two control systems. The other of the two control systems is used for vertical displacement of the cartridge.

Abstract: A sonobuoy system and method for deploying an array of transducers in a substantially horizontal line at a desired depth belowe the surface of a body of water. The trailing end of the array is deployed first, allowed to descend, and suspended at the desired operating depth. The leading end of the array is then released, allowed to descend slowly, and suspended at the desired operating depth. A drag device attached to the trailing end of the array causes the trailing end of the array to be stretched out away from the leading end, thereby maintaining the array in a substantial horizontal line at the desired depth. The system and method make it possible to deploy horizontal line arrays in a minimum of time and at shallow depths.

Abstract: A system is disclosed for predicting and modifying broadband periodic and aperiodic signals in real time. A signal to be predicted is detected and successively sampled over time and stored. An adaptive filter (28) predicts a next successive signal based on the sum of a predefined number of stored, successive samples(50). Each one of the stored samples is multiplied by a corresponding filter coefficient (61). The predicted signal generated by the adaptive filter is used to modify or cancel the detected signal. A residual error (e(n)) is determined from the predicted signal and the detected signal. The filter coefficients are modified(70) based on the residual error and the energy (E) of the stored signal samples.

Abstract: A process is described for eliminating acid impurities and heavy metal impurities from liquids, in particular acidic waste waters and also from the acidic concentrates draining from the chimneys of industrial and municipal incineration plants, in which process the liquid is passed into a vessel containing a basic neutralisation medium and is conducted away after a reaction time sufficient for the neutralisation. The neutralisation is carried out with a pelleted material containing essentially bases of the 2nd main group of the Periodic Table, in particular magnesium hydroxide, the liquid, prior to entry into the neutralisation step, being first passed through a packing of pellets containing organo-bentonite and after the neutralisation through a packing of pellets essentially containing iron III hydroxide. To eliminate the acid impurities and heavy metal impurities from the acidic concentrates draining from the chimneys of industrial and municipal incineration plants, in a precleaning stage to eliminate the volatile acid-forming pollutants contained in the flue gases, the flue gases are passed through one packing each of pelleted reaction materials, which essentially contain magnesium hydroxide and/or manganese dioxide and/or dimanganese trioxide.
