METHOD OF APPLYING INSULATING MATERIAL TO WINDINGS IN ELECTRICAL MACHINERY ABSTRACT OF THE DISCLOSURE A method of applying solventless varnish to stator windings in electrical machinery. A magnetic core having a plurality of stator windings disposed in the slots of the core is positioned above a tank containing a solventless varnish, and the tank is then raised to immerse the end turns of the windings on one end of the core into the varnish. The windings are energized to heat them and the varnish which adheres to the end turns. The tank is then lowered and the stator and windings are inverted so that a portion of the varnish which adheres to the end turns flows downwardly through the slots of the stator. This is repeated until varnish begins to flow freely through the slots to the other end, thereby indicating that good coating of the winding within the slots has been accomplished. Next, the current through the windings is increased to raise the temperature of the end turns of the windings to the gel point of the varnish, and the end turns on both ends of the stator are then alternately dipped into the varnish bath to build up a protective coating on the end turns. Once a sufficient thickness has been achieved, the current through the windings is increased further to raise the temperatures of the windings to the point where the adhered varnish cures. The stator is then placed in an oven for several minutes to cure the varnish on components that are not heated by the resistance heating of the windings, such as the winding leads and slot insulation.

Allocation of pilot signatures for channel estimation in a cellular radio communications system

The invention relates to a method for generating pilot signatures for channel estimation in a cellular radio communications system comprising a transmitting user station and a receiving base station that is allocated to a radio cell, said stations being interconnected via an upward channel. The channel estimation for the upward channel is based on an analysis of a pilot signature that is transmitted by a user station. According to the invention, a different column vector of a Hadamard matrix is allocated as a pilot signature to each user station of the radio cell. Said inventive method leads to a negligible degradation of the signal-to-noise ratio.

Impeller locking collar

Technologies are generally described for holding an impeller of a pump assembly in place axially with an impeller locking collar by loading the collar against a ring element. In a centrifugal pump assembly, one side of the shaft has a larger diameter for the impeller to abut against. The other side of the shaft may be fitted with an impeller locking collar comprising two portions that can be threaded together and hold the impeller in place by tightening against a ring element such as a split ring or spiral lock. Anti-rotation to avoid loosening of the impeller locking collar may be achieved by providing counter threads against a shaft rotation. Secondary anti-rotation may be provided by one or more set screws in the impeller locking collar.

Predicting binary outcomes of an activity

A binary outcome of an activity is predicted based on samples of the activity. The activity is characterized by features that can take on any of a set of mutually exclusive levels. An initial candidate pool of terms is selected. The terms are feature levels or combinations of feature levels. The candidate terms are used to create two ordered pools of terms, one including terms that are positively predictive and another including terms that are negatively predictive. The terms in each pool are ordered by strength of predictiveness and diversity of predictiveness relative to terms higher in the order. A final set of terms is selected by combining terms from these two pools.
