摘要:
This invention relates generally to methods for removing adherent materials, for example, residues, scale, contaminants, fouling, precipitates, and the like objectional materials from various internal surfaces of fluid transport or delivery systems and parts thereof. In particular, the method employs an improved media comprising core/shell particles. The media can be propelled against or along the surface by a fluid carrier to remove the unwanted surface material. In one embodiment, the media may be propelled by a liquid along a surface, such as the interior walls of a pipe, to remove undesirable adherent materials.

The present invention is a photographic element which includes a support, at least one silver halide emulsion layer; and at least one layer containing a binder and polymer particles. The polymeric particles are prepared by the process of mechanically forming droplets having a size less than 400 nm of an ethylenically unsaturated monomer having hydrophobic groups, the hydrophobic groups having a logP.sub.(calc) greater than a logP.sub.(calc) of the ethylenically unsaturated monomer by at least 1 unit, and polymerizing said droplets so that the polymerized droplets have a size of less than 400 nm. The present invention also is a photographic element which includes a support, at least one silver halide emulsion layer; and at least one layer containing a binder and polymer particles. The polymeric particles are prepared by the process of mechanically forming droplets having a size less than 400 nm of an ethylenically unsaturated monomer having a logP.sub.(calc) greater than 4, preferably greater than 6, and polymerizing said droplets so that the polymerized droplets have a size of less than 400 nm.

An electric motor (2) for a clothes washing machine including the motor and a drive, the motor having a stator (25) held outboard of a frame carrying bearings (37, 38) in which a shaft (11) rotates, the shaft carrying the rotor (21) outboard of the stator (25), and permanent magnets (17) on an inner face of the rotor. The stator (25) is formed as an annular helical yoke edgewise wound from a strip of magnetic material and having an inner face and an outer face, the strip having pole pieces (8) formed integrally therewith extending from one edge of the strip and the strip being edgewise wound whereby the pole pieces coincide in stacked groups to form a plurality of poles arranged at equally spaced intervals extending radially outwardly from the outer face of the yoke. Energizable stator windings (26) are wound directly on the poles (8) of the stator and are adapted to be energized through an electronic commutation circuit (65,66) and the rotor (21) is mounted for rotation exteriorly of and relative to the stator, the rotor comprising a backing ring (16) of magnetic material and a series of permanent magnets (17) held at spaced-apart intervals on an inner surface of the backing ring (16) and opposing the poles (8) of the stator (25).

An electric motor, a drive and a clothes washing machine including the motor and drive, the motor having a stator held outboard of a frame carrying bearings in which a shaft rotates, the shaft carrying the rotor outboard of the stator, the rotor having permanent magnets on an inner face thereof. The shaft carries an agitator and a spin tub of the clothes washing machine, and interconnecting members between a part rotatable with the agitator and a part rotatable with the spin tub are movable axially on the shaft relative to each other by a buoyancy system which is operated by the absence or presence of water in a container of the clothes washing machine to connect the spin tub and the agitator, to be driven by the shaft continuously in one direction for spinning clothes when water is at a low level in or absent from the container, and to disconnect the spin tub from the shaft, leaving the agitator still connected to the shaft when sufficient water is in the container so that rotation of the shaft backwards and forwards by the motor washes clothes in the spin tub by backwards and forwards movement of the agitator.
