Class 360: Dynamic Magnetic Information Storage Or RetrievalThis class is an integral part of Class 369, Dynamic Information Storage or Retrieval, and is the specific class for apparatus and corresponding processes for the storage and retrieval of information based on relative movement between a magnetic record carrier and a transducer. It includes apparatus and corresponding processes for making copies or editing of records falling within the above definition. A magnetic record carrier within the meaning of this class is an element which consists of a magnetizable material or is comprised of a coating or impregnation of magnetizable material which is intended for the storage of more than a single bit of information.

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass E43.005: Selection of materials (EPO)
Class 324: Electricity: Measuring And TestingThis is the residual home for all subject matter, not elsewhere classified, relating to the measuring, testing (or sensing) of electric properties, (e.g., determining ground resistivity, determining frequency of an alternating current, determining kilowatt hour demand), or the measuring, testing or sensing of nonelectric properties by electric means (e.g., determining moisture, a nonelectric property, by measuring conductance with a resistance bridge; determining speed, a nonelectric property by use of an electric tachometer).
Subclass 207.21: Magnetoresistive
Subclass 210: Magnetic information storage element testing
Subclass 252: Semiconductor type solid-state or magnetoresistive magnetometers
Class 338: Electrical ResistorsElectrical resistors with solid, granular, or liquid resistance elements. These resistors may be either fixed or variable in resistance value. Semiconductors are included if limited by claimed subject matter to resistance properties, such as exists in photoconductive and thermistor type resistors. Included also are resistors with perfecting structure such as resistors whose resistance value is temperature compensated, or mounted on wheels or on a vehicle, resistors with heat dissipating projections, or with cooling gas or liquid circulation, or with heat storing, or with inductance or capacity reducing, or with electrical shields, or with a cleaner or a setting indicator in a mechanically variable resistor, or with a casing or housing, or with protecting structure spaced from the element, or with mounting or supporting means. Included also are resistors combined with or incorporated in other structure, as are resistors constructed as by shape or from material to change their resistance value particularly well in response to a particular condition or change in a particular condition such as current and/or voltage. Included are resistors usually of the mechanically variable type together with a condition sensing actuator which changes the mechanical adjustment of the resistor in response to a condition or a change in condition.
Subclass 32R: Magnetic field or compass (e.g., Hall effect type)
Class 228: Metal Fusion BondingMethod of joining the meeting faces of juxtaposed or engaged metal work parts or of the same part originally in a form-sustaining state, by the direct application of heat and/or mechanical energy to either of: (a) such work parts, to such an extent as to effect a flowing or blending together of some of the metal in neighboring regions of said work parts into a continuous metallic zone interconnecting said work parts, or (b) such work parts and a metallic filler, to such an extent as to effect a flowing or blending together of the filler and some of the metal of said work portions into a continuous metallic zone interconnecting said work portions with filler and thus with each other.

The coating may be hard or soft, permanent or transitory, supplied solely by extraneous materials or supplied wholly or in part by the base material. B. impregnating a base by causing a coating material to extend or penetrate into the base material, or into the interstices of a porous, cellular or foraminous material. C. taking preparatory treatments of the base material, subsequent treatments of the coated base material and other ancillary noncoating operations claimed, per se, processes limited to etching for making a base more compatible with, or adherent to, the coating wherein the base is the substrate (work) onto which a coating is applied are included.
