Abstract: A set of magnetic assemblies for treating fluids including water and liquid and gaseous fuels wherein each assembly includes a construction of permanent magnets and pole pieces arranged to optimize a "Figure of merit" number defined as the integral of the absolute value of magnetic field intensity over region occupied by the fluid. In one embodiment, each assembly includes an elongated magnet with permeable pole pieces at each end bent back toward each other to form a gap equal to one half the length of the magnet. In another arrangement, each assembly includes a permanent magnet having a pole piece leading around toward the flux surface at the other end of the magnet, adjacent to the fluid carrier. Dimensions of the area of the pole end surface are selected based on the permeability of the pole piece, magnetization intensity of the permanent magnet material and pipe diameter to maximize the Figure of merit. Figure of merit is maximized by placing an odd number of assemblies around the conduit.

Abstract: A bearing system including one or more bearings for optimizing stiffness of each bearing which includes an individual regulator, pressure meter and flow meter to each bearing. The meters send instantaneous values of pressure an flow rate to a computer system which performs an algorithm using the values and computes target signal values for each individual bearing. These values are then transmitted to the respective pressure regulators. The pressures applied by the regulators are maximum values with which the bearing can operate without going into vibration. One algorithm that the computer uses is to compute an "impedance" value of the bearing which is defined to be P/S where P is the pressure measured by the pressure meter and S is the flow rate measured by the flowmeter. This approach assumes that the actual effective pressure in the bearing is at last proportional to the pressure measured at the meter.

Abstract: A carrier for transporting delicate devices (articles) expecially integrated circuits comprising a tube with a row of openings in its wall and separators attached to an elongated member wherein each separator fits into one of the openings thereby separating the interior of the tube into a row of spaces such that a device is positioned in each space and maintained out of contact with other devices. The separator may have one of several forms including a short wall or a stub. In one embodiment, the elongated member is a channel that straddles the tube in one position where the separators are inserted into the interior of the tube and in another position where the separators are withdrawn from the interior of the tube.

Abstract: A device for measuring force of bending of a head-flexure assembly by a given amount characterized by the distance between a clamping surface for one end of the flexure and the plane (recording surface) in contact with the head at at the other end of the flexure. The device includes a load cell with a cell reference surface adjustably supported on a cell base which is slidably mounted on a main base. Adjustment of the location of the cell reference surface with respect to the clamp surface is achieved by a shaft threaded into the load cell with a first thread and threaded into the main base with a second thread so that by turning the shaft, the distance between the two reference surfaces can be very accurately adjusted. When the load cell is deformed by application of the head loading force to the cell reference surface, a signal from the load cell actuates a mechanism maintaining the cell reference surface in its initial location thereby maintaining the initial flexion of the flexure.

Abstract: A method and device for reordering items stored as groups in an inventory of items which includes an order sheet and a group of labels deposited with each group of items. Each label has a part number corresponding to the item and an index mark printed on one side and a second side treated with a peelable adhesive. When an item is withdrawn from a group of items, a label is attached to a sheet which thus becomes an order sheet. Index marks are printed on the order sheet which are aligned with index marks printed on each label. When the customer desires to order items to replenish depleted stock, he mails or "faxes" the order sheet to the supplier. The supplier may then (either manually or with character reading equipment) identify the item to be ordered and the quantity to be ordered from the number of labels on the order sheet. He may then compute price, taxes, etc., and print out an order form using this information. The index marks may simply be lines.
