Abstract: A method and apparatus for inhibiting scaling in an electrodeionization system or in a combined reverse osmosis/electrodeionization system for water treatment and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit to inhibit precipitation of metal cations contained in the feed water and for increasing efficiency of the electrodeionization system. Water to be purified is passed through a electrodeionization unit in which a concentrate stream recycling through concentrating compartments and anode and cathode compartments contains effective amounts of an antiscalant to inhibit precipitation of scale. One or more preliminary reverse osmosis units in series with the electrodeionization unit preferably receives a portion of the antiscalants in the concentrate stream. The antiscalant in the water fed to the reverse osmosis unit can be supplemented and adjusted.

The frequency ambiguities which result from sampling an input signal below the Nyquist rate are resolved by simultaneously sampling the signal at multiple sample frequencies and then using a lookup table to identify the unique mapping of the common signal into the multiple sample frequency baselines.

Abstract: A vehicle with an electric power steering system has a steering shaft with a resonant frequency of free rotational oscillation and a control which derives a driver assist torque signal, a return to center torque signal and an active damping torque signal and sums these signals to provide a motor command signal to the electric motor. The active damping torque signal is derived by filtering a generated steering shaft position signal in a filter having amplitude and phase characteristics of a differentiator from zero Hertz only through the resonant frequency of free rotational oscillation of the steering shaft and multiplying the filtered steering shaft position signal by a vehicle velocity factor derived from sensed vehicle velocity. Preferably, the electric motor is provided with one or more rotor position sensors used in the control thereof and rotor position signals from the rotor position sensors are provided as the steering shaft position signal.

Abstract: When a computer system is upgraded, such as by adding a more advanced processor chip and/or a new operating system, a different page size may be employed. The page size is altered for data previously stored in a storage medium such as a hard disk in the computer system, without removing all of the data from the medium and rewriting it. Data is stored in the medium in blocks or sectors which have headers defining the block. Also, tables define memory objects and segments, and locate virtual memory addresses in physical memory. The headers and/or tables can be changed without rewriting all of the data in the sectors or pages in physical memory, so the page size is changed to accommodate the new system components, without excessive burden on system hardware or undue expenditure of time.

Each arm has an inside surface with a spindle connected thereto and an outer shirttail surface. Each spindle projects generally downwardly and inwardly with respect to its associated arm, has a generally cylindrical upper end portion connected to the associated inside surface, and has an inner sealing surface on the upper end portion. A number of rotary cone cutters equal to the number of arms are each mounted on respective spindles.

Abstract: A cavity is charged with particulate material by positioning a predetermined quantity of the material in a box (140). The box has substantially the same horizontal cross-sectional shape as the cavity and is closed at the bottom by at least one door (78) on which the material rests. In order to level the material, the box (140) is moved to and fro horizontally a plurality of times with the energy imparted to the material being progressively reduced during the movements. The door (78) is then opened sufficiently rapidly that the particulate material falls out of the box (140) into the cavity substantially as a unit.

Abstract: The body of a PIN photodiode is of a silicon semiconductor material. The PIN photodiode has a large area incident surface on which light impinges and is operated at high voltages. In the fabrication of a PIN photodiode, as described, a high concentration of N-type dopant is deposited on the body. It has been discovered that if a phosphorus silicate glass, as a source of N-type dopant, is in contact with a surface of the PIN photodiode body in a high temperature ambient and for an extended period of time, lattice damage on the surface of the silicon body results. These lattice defects are responsible for premature voltage breakdown in the device. In a first method of fabrication of PIN photodiode devices the phosphorus silicate glass is on the silicon surface for about 12 minutes after which it is removed and then any phosphorus atoms in the surface of the body are diffused into the body.
